In the absence of a standardized diagnosis system, many popular, informal classification systems or checklists, outside the DSM and ICD, were created out of clinical and parental experience within the field known as attachment therapy. These lists are unvalidated and critics state they are inaccurate, too broadly defined or applied by unqualified persons. Many are found on the websites of attachment therapists. Common elements of these lists such as lying, lack of remorse or conscience and cruelty do not form part of the diagnostic criteria under either DSM-IV-TR or ICD-10. Many children are being diagnosed with RAD because of behavioral problems that are outside the criteria. There is an emphasis within attachment therapy on aggressive behavior as a symptom of what they describe as attachment disorder whereas mainstream theorists view these behaviors as comorbid, externalizing behaviors requiring appropriate assessment and treatment rather than attachment disorders. However, knowledge of attachment relationships can contribute to the cause, maintenance and treatment of externalizing disorders.

The Randolph Attachment Disorder Questionnaire or RADQ is one of the better known of these checklists and is used by attachment therapists and others. The checklist includes 93 discrete behaviours, many of which either overlap with other disorders, like conduct disorder and oppositional defiant disorder, or are not related to attachment difficulties. Critics assert that it is unvalidated and lacks specificity.

The diagnostic complexities of RAD mean that careful diagnostic evaluation by a trained mental health expert with particular expertise in differential diagnosis is considered essential. Several other disorders, such as conduct disorders, oppositional defiant disorder, anxiety disorders, post traumatic stress disorder and social phobia share many symptoms and are often comorbid with or confused with RAD, leading to over and under diagnosis. RAD can also be confused with neuropsychiatric disorders such as autism, pervasive developmental disorder, childhood schizophrenia and some genetic syndromes. Infants with this disorder can be distinguished from those with organic illness by their rapid physical improvement after hospitalization. Autistic children are likely to be of normal size and weight and often exhibit a degree of intellectual disability. They are unlikely to improve upon being removed from the home.

For a child or adolescent to qualify for a diagnosis of ODD, behaviours must cause considerable distress for the family or interfere significantly with academic or social functioning. Interference might take the form of preventing the child or adolescent from learning at school or making friends, or placing him or her in harmful situations. These behaviours must also persist for at least six months. Effects of ODD can be greatly amplified by other disorders in comorbidity such as ADHD. Other common comorbid disorders include depression and substance use disorders.

The person's appearance, behavior, and history, along with a psychological evaluation, are usually sufficient to establish a diagnosis. There is no test to confirm this diagnosis. Because the criteria are subjective, some people may be wrongly diagnosed.

The previous edition of the Diagnostic and Statistical Manual of Mental Disorders, DSM IV-TR, defines histrionic personality disorder (in Cluster B) as:

The DSM-IV requires that a diagnosis for any specific personality disorder also satisfies a set of general personality disorder criteria.

Approaches to the treatment of ODD include parent management training, individual psychotherapy, family therapy, cognitive behavioral therapy, and social skills training. According to the American Academy of Child and Adolescent Psychiatry, treatments for ODD are tailored specifically to the individual child, and different treatment techniques are applied for pre-schoolers and adolescents. Several preventative programs have had a positive effect on those at high risk for ODD. Both home visitation and programs such as Head Start have shown some effectiveness in preschool children. Social skills training, parent management training, and anger management programs have been used as prevention programs for school-age children at risk for ODD. For adolescents at risk for ODD, cognitive interventions, vocational training and academic tutoring have shown preventative effectiveness. There is also limited evidence that the atypical antipsychotic medication risperidone decreases aggression and conduct problems in youth with disruptive behavioral disorders, such as ODD.

The utility of PTSD derived psychotherapies for assisting children with C-PTSD is uncertain. This area of diagnosis and treatment calls for caution in use of the category C-PTSD. Ford and van der Kolk have suggested that C-PTSD may not be as useful a category for diagnosis and treatment of children as a proposed category of developmental trauma disorder (DTD). For DTD to be diagnosed it requires a

'history of exposure to early life developmentally adverse interpersonal trauma such as sexual abuse, physical abuse, violence, traumatic losses of other significant disruption or betrayal of the child's relationships with primary caregivers, which has been postulated as an etiological basis for complex traumatic stress disorders. Diagnosis, treatment planning and outcome are always relational.'

Since C-PTSD or DTD in children is often caused by chronic maltreatment, neglect or abuse in a care-giving relationship the first element of the biopsychosocial system to address is that relationship. This invariably involves some sort of child protection agency. This both widens the range of support that can be given to the child but also the complexity of the situation, since the agency's statutory legal obligations may then need to be enforced.

A number of practical, therapeutic and ethical principles for assessment and intervention have been developed and explored in the field:

- Identifying and addressing threats to the child's or family's safety and stability are the first priority.

- A relational bridge must be developed to engage, retain and maximize the benefit for the child and caregiver.

- Diagnosis, treatment planning and outcome monitoring are always relational (and) strengths based.

- All phases of treatment should aim to enhance self-regulation competencies.

- Determining with whom, when and how to address traumatic memories.

- Preventing and managing relational discontinuities and psychosocial crises.

The ICD-10 includes a diagnostic guideline for the wide group of personality and behavioural disorders. However, every disorder has its own diagnostic criteria. In case of the organic personality disorder, patient has to show at least three of the following diagnostic criteria over a six or more months period. organic personality disorder is associated with a large variety of symptoms, such as deficits in cognitive function, dysfunctional behaviours, psychosis, neurosis, emotional changes, alterations in expression function and irritability. Patients with organic personality disorder can present emotional lability that means their emotional expressions are unstable and fluctuating. In addition, patients show reduction in ability of perseverance with their goals and they express disinhibited behaviours, which are characterised by inappropriate sexual and antisocial actions. For instance, patients can show dissocial behaviours, like stealing. Moreover, according to diagnostic guideline of ICD-10, patients can suffer from cognitive disturbances and they present signs of suspiciousness and paranoid ideas. Additionally, patients may present alteration in process of language production that means there are changes in language rate and flow. Furthermore, patients may show changes in their sexual preference and hyposexuality symptoms.

Another common feature of personality of patients with organic personality disorder is their dysfunctional and maladaptive behaviour that causes serious problems in these patients, because they face problems with pursuit and achievement of their goals. It is worth to be mentioned that patients with organic personality disorder express a feeling of unreasonable satisfaction and euphoria. Also, the patients show aggressive behaviours sometimes and these serious dysfunctions in their behaviour can have effects on their life and their relationships with other people. Specifically patients show intense signs of anger and aggression because of their inability to handle their impulses. The type of this aggression is called "impulsive aggression". Furthermore, it is worth to be mentioned that the pattern of organic personality disorder presents some similarities with pattern of temporal lobe epilepsy (TLE). Specifically patients who suffer from this chronic disorder type of epilepsy, express aggressive behaviours, likewise it happens to patients with organic personality disorder. Another similar symptom between Temporal lobe epilepsy and organic personality disorder is the epileptic seizure. The symptom of epileptic seizure has influence on patients' personality that means it causes behavioural alterations". The Temporal lobe epilepsy (TLE) is associated with the hyperexcitability of the medial temporal lobe (MTL) of patients. Finally, patients with organic personality disorder may present similar symptoms with patients, who suffer from the Huntington's disease as well. The symptoms of apathy and irritability are common between these two groups of patients.

Dissociative disorders (DD) are widely believed to have roots in traumatic childhood experience (abuse or loss), but symptomology often goes unrecognized or is misdiagnosed in children and adolescents. There are several reasons why recognizing symptoms of dissociation in children is challenging: it may be difficult for children to describe their internal experiences; caregivers may miss signals or attempt to conceal their own abusive or neglectful behaviors; symptoms can be subtle or fleeting; disturbances of memory, mood, or concentration associated with dissociation may be misinterpreted as symptoms of other disorders.

In addition to developing diagnostic tests for children and adolescents (see above), a number of approaches have been developed to improve recognition and understanding of dissociation in children. Recent research has focused on clarifying the neurological basis of symptoms associated with dissociation by studying neurochemical, functional and structural brain abnormalities that can result from childhood trauma. Others in the field have argued that recognizing disorganized attachment (DA) in children can help alert clinicians to the possibility of dissociative disorders.

Clinicians and researchers also stress the importance of using a developmental model to understand both symptoms and the future course of DDs. In other words, symptoms of dissociation may manifest differently at different stages of child and adolescent development and individuals may be more or less susceptible to developing dissociative symptoms at different ages. Further research into the manifestation of dissociative symptoms and vulnerability throughout development is needed. Related to this developmental approach, more research is required to establish whether a young patient’s recovery will remain stable over time.

As it has already been mentioned, patients with organic personality disorder show a wide variety of sudden behavioural changes and dysfunctions. There are not a lot of information about the treatment of this mental health disorder. The pharmacological approach is the most common therapy among patients with organic personality disorder. However, the choice of drug therapy relies on the seriousness of patient's situation and what symptoms are shown. The choice and administration of specific drugs contribute to the reduction of symptoms of organic personality disorder. For this reason, it is crucial for patients' treatment to be assessed by clinical psychologists and psychiatrists before the administration of drug.

Additionally, the dysfunctions in expression of behaviour of patients with organic personality disorder and the development of symptom of irritability, which are caused by aggressive and self-injurious behaviours, can be dealt with the administration of carbamazepine. Moreover, the symptoms of this disorder can be decreased by the administration of valproic acid. Also, emotional irritability and signs of depression can be dealt with the use of nortriptyline and low-dose thioridazine. Except from the symptom of irritability, patients express aggressive behaviours. At the onset of drug therapy for effective treatment of anger and aggression, the drug of carbamazepine, phenobarbital, benztropine and haloperidol can be administrated in order to reduce the symptoms of patients with organic personality disorder. In addition, the use of propranolol may decrease the frequent behaviours of rage attacks.

Finally, it is important for patients to take part in psychotherapy sessions during the period of drug therapy. In this way, there is prevention and patients can be protected by negative effects of drugs on their organism and their behaviour. Furthermore, the clinicians can provide useful and helpful support to patients during these psychotherapy sessions. Thus, the combination of drug therapy with psychotherapy can lead to the reduction of symptoms of this disorder and the improvement of patients' situation.

The lifetime prevalence of dissociative disorders varies from 10% in the general population to 46% in psychiatric inpatients. Diagnosis can be made with the help of structured interviews such as the Dissociative Disorders Interview Schedule (DDIS) and the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D), or with the Dissociative Experiences Scale (DES) which is a self-assessment questionnaire. Some diagnostic tests have also been adapted and/or developed for use with children and adolescents such as the Children's Version of the Response Evaluation Measure (REM-Y-71), Child Interview for Subjective Dissociative Experiences, Child Dissociative Checklist (CDC), Child Behavior Checklist (CBCL) Dissociation Subscale, and the Trauma Symptom Checklist for Children Dissociation Subscale.

There are problems with classification, diagnosis and therapeutic strategies of dissociative and conversion disorders which can be understood by the historic context of hysteria. Even current systems used to diagnose DD such as the DSM-IV and ICD-10 differ in the way the classification is determined. In most cases mental health professionals are still hesitant to diagnose patients with Dissociative Disorder, because before they are considered to be diagnosed with Dissociative Disorder these patients have more than likely been diagnosed with major depression, anxiety disorder, and most often post-traumatic disorder.

An important concern in the diagnosis of dissociative disorders is the possibility that the patient may be feigning symptoms in order to escape negative consequences. Young criminal offenders report much higher levels of dissociative disorders, such as amnesia. In one study it was found that 1% of young offenders reported complete amnesia for a violent crime, while 19% claimed partial amnesia. There have also been incidences in which people with dissociative identity disorder provide conflicting testimonies in court, depending on the personality that is present.

There are a variety of mainstream prevention programs and treatment approaches for attachment disorder, attachment problems and moods or behaviors considered to be potential problems within the context of attachment theory. All such approaches for infants and younger children concentrate on increasing the responsiveness and sensitivity of the caregiver, or if that is not possible, changing the caregiver. Such approaches include 'Watch, wait and wonder,' manipulation of sensitive responsiveness, modified 'Interaction Guidance,'. 'Preschool Parent Psychotherapy,'. Circle of Security', Attachment and Biobehavioral Catch-up (ABC), the New Orleans Intervention, and Parent-Child psychotherapy. Other known treatment methods include Developmental, Individual-difference, Relationship-based therapy (DIR) (also referred to as "Floor Time") by Stanley Greenspan, although DIR is primarily directed to treatment of pervasive developmental disorders Some of these approaches, such as that suggested by Dozier, consider the attachment status of the adult caregiver to play an important role in the development of the emotional connection between adult and child. This includes foster parents, as children with poor attachment experiences often do not elicit appropriate caregiver responses from their attachment behaviors despite 'normative' care.

Treatment for reactive attachment disorder for children usually involves a mix of therapy, counseling, and parenting education. These must be designed to make sure the child has a safe environment to live in and to develop positive interactions with caregivers and improves their relationships with their peers.

Medication can be used as a way to treat similar conditions, like depression, anxiety, or hyperactivity; however, there is no quick fix for treating reactive attachment disorder. A pediatrician may recommend a treatment plan. For example, a mix of family therapy, individual psychological counseling, play therapy, special education services and parenting skills classes.

Attachment disorder is a broad term intended to describe disorders of mood, behavior, and social relationships arising from a failure to form normal attachments to primary care giving figures in early childhood. Such a failure would result from unusual early experiences of neglect, abuse, abrupt separation from caregivers between 6 months and three years of age, frequent change or excessive numbers of caregivers, or lack of caregiver responsiveness to child communicative efforts resulting in a lack of basic trust. A problematic history of social relationships occurring after about age three may be distressing to a child, but does not result in attachment disorder.

The term attachment disorder is used to describe emotional and behavioral problems of young children, and also applied to school-age children, teenagers and adults. The specific difficulties implied depend on the age of the individual being assessed, and a child's attachment-related behaviors may be very different with one familiar adult than with another, suggesting that the disorder is within the relationship and interactions of the two people rather than an aspect of one or the other personality. No list of symptoms can legitimately be presented but generally the term attachment disorder refers to the absence or distortion of age appropriate social behaviors with adults. For example, in a toddler, attachment-disordered behavior could include a failure to stay near familiar adults in a strange environment or to be comforted by contact with a familiar person, whereas in a six-year-old attachment-disordered behavior might involve excessive friendliness and inappropriate approaches to strangers.

There are currently two main areas of theory and practice relating to the definition and diagnosis of attachment disorder, and considerable discussion about a broader definition altogether. The first main area is based on scientific enquiry, is found in academic journals and books and pays close attention to attachment theory. It is described in ICD-10 as reactive attachment disorder, or "RAD" for the inhibited form, and disinhibited attachment disorder, or "DAD" for the disinhibited form. In DSM-IV-TR both comparable inhibited and disinhibited types are called reactive attachment disorder or "RAD".

The second area is controversial and considered pseudoscientific. It is found in clinical practice, on websites and in books and publications, but has little or no evidence base. It makes controversial claims relating to a basis in attachment theory. The use of these controversial diagnoses of attachment disorder is linked to the use of pseudoscientific attachment therapies to treat them.

Some authors have suggested that attachment, as an aspect of emotional development, is better assessed along a spectrum than considered to fall into two non-overlapping categories. This spectrum would have at one end the characteristics called secure attachment; midway along the range of disturbance would be insecure or other undesirable attachment styles; at the other extreme would be

non-attachment. Agreement has not yet been reached with respect to diagnostic criteria.

Finally, the term is also sometimes used to cover difficulties arising in relation to various attachment styles which may not be disorders in the clinical sense.

Not only are there significant health risks associated with compulsive hoarding, but scientists are also trying to pinpoint how significant the interference is with occupational and social functioning in a hoarder's daily life. In a pool of compulsive hoarders, 42% found their behavior problematic to the 63% of their family and friends who saw the behavior as problematic. The findings suggest that individuals who hoard may exhibit impaired sensitivity to their own and others’ emotions, and conversely, relate the world around them by forming attachments to possessions rather than to people. Lower emotional intelligence among hoarding patients may also impact their ability to discard and organize their possessions. With such detrimental characteristics, comprehensive research has been performed to find a cure. Although this is ongoing research, most investigations have found that only a third of patients who hoard show an adequate response to these medications and therapeutic interventions.

With the modifications to the DSM, insurance coverage for treatments will change as well as special education programs.

Reactive strategies include:

- Redirection: distracting the person by offering another activity, or changing the topic of conversation. Offer the person a choice of 2 or 3 things, but no more than 3, because this can be overwhelming. In offering a choice, make sure to pause to allow the person time to process the information and give a response.

- Talking to the person and finding out what the problem is

- Working out what the person's behaviour is trying to communicate

- Crisis management

According to Michael First of the DSM-5 working committee the focus of a relational disorder, in contrast to other DSM-IV disorders, "is on the relationship rather than on any one individual in the relationship".

Relational disorders involve two or more individuals and a disordered "juncture", whereas typical Axis I psychopathology describes a disorder at the individual level. An additional criterion for a relational disorder is that the disorder cannot be due solely to a problem in one member of the relationship, but requires pathological interaction from each of the individuals involved in the relationship.

For example, if a parent is withdrawn from one child but not another, the could be attributed to a relational disorder. In contrast, if a parent is withdrawn from both children, the dysfunction may be more appropriately attributable to a disorder at the individual level.

First states that "relational disorders share many elements in common with other disorders: there are distinctive features for classification; they can cause clinically significant impairment; there are recognizable clinical courses and patterns of comorbidity; they respond to specific treatments; and they can be prevented with early interventions. Specific tasks in a proposed research agenda: develop assessment modules; determine the clinical utility of relational disorders; determine the role of relational disorders in the etiology and maintenance of individual disorders; and consider aspects of relational disorders that might be modulated by individual disorders."

The proposed new diagnosis defines a relational disorder as "persistent and painful patterns of feelings, behaviors, and perceptions" among two or more people in an important personal relationship, such a husband and wife, or a parent and children.

According to psychiatrist Darrel Regier, MD, some psychiatrists and other therapists involved in couples and marital counseling have recommended that the new diagnosis be considered for possible incorporation into the Diagnostic and Statistical Manual of Mental Disorders (DSM IV).

Proactive strategies to prevent problems can include:

- Change the environment: This can include increasing opportunities for access to a variety of activities, balancing cognitively and physically demanding activities with periods of rest, providing a predictable environment in order to reduce the level of cognitive demands on the person, trying to provide consistent routines (be mindful of events that may not occur, try not to make promises that cannot be kept, if unable to go out at a particular time then say so), checking for safety in the home environment (e.g. changing/moving furniture).

- Teach a skill: These can include general skills development of useful communication strategies, coping skills (e.g. teach the person what to do when feeling angry, anxious)

- Individual behaviour support plans: These involve reinforcing specific desirable behaviour and ignoring the specific undesirable behaviour (unless it is dangerous, the priority is to keep both people safe through a crisis plan which might involve removing sharp objects or weapons, escaping to a safe place, giving the person time to calm down), avoiding things you know upsets the person, strategies to increase engagement in activities.

Broadly speaking, when the behaviour occurs, assertively in a nonjudgemental, clear, unambiguous way provide feedback that the behaviour is inappropriate, and say what you prefer instead. For example, "Jane, you're standing too close when you are speaking to me, I feel uncomfortable, please take a step back", or "I don't like it when you say I look hot in front of your wife, I feel uncomfortable, I am your Attendant Carer/Support Worker, I am here to help you with your shopping". Then re-direct to the next activity. Any subsequent behaviour ignore. Then generally, as almost all behaviour is communication, understand what the behaviour is trying to communicate and look at ways to have the need met in more appropriate ways.

The PCL-R, the PCL:SV, and the PCL:YV are highly regarded and widely used in criminal justice settings, particularly in North America. They may be used for risk assessment and for assessing treatment potential and be used as part of the decisions regarding bail, sentence, which prison to use, parole, and regarding whether a youth should be tried as a juvenile or as an adult. There have been several criticisms against its use in legal settings. They include the general criticisms against the PCL-R, the availability of other risk assessment tools which may have advantages, and the excessive pessimism surrounding the prognosis and treatment possibilities of those who are diagnosed with psychopathy.

The interrater reliability of the PCL-R can be high when used carefully in research but tend to be poor in applied settings. In particular Factor 1 items are somewhat subjective. In sexually violent predator cases the PCL-R scores given by prosecution experts were consistently higher than those given by defense experts in one study. The scoring may also be influenced by other differences between raters. In one study it was estimated that of the PCL-R variance, about 45% was due to true offender differences, 20% was due to which side the rater testified for, and 30% was due to other rater differences.

To aid a criminal investigation, certain interrogation approaches may be used to exploit and leverage the personality traits of suspects thought to have psychopathy and make them more likely to divulge information.

Mental retardation is coded on Axis II of the DSM-IV-TR. The diagnostic criteria necessary in order to diagnose intellectual disability consists of:

There are varying degrees of intellectual disability, which are identified by an IQ test.

Mental retardation, Severity Unspecified: This unspecified diagnosis is given when there is a strong assumption that the child is mentally retarded, but cannot be tested because the individual is too impaired, not willing to take the IQ test or is an infant.

Complex post-traumatic stress disorder (C-PTSD; also known as complex trauma disorder) is a psychological disorder thought to occur as a result of repetitive, prolonged trauma involving harm or abandonment by a caregiver or other interpersonal relationships with an uneven power dynamic. C-PTSD is associated with sexual, emotional or physical abuse or neglect in childhood, intimate partner violence, victims of kidnapping and hostage situations, indentured servants, victims of slavery, sweatshop workers, prisoners of war, victims of bullying, concentration camp survivors, and defectors of cults or cult-like organizations. Situations involving captivity/entrapment (a situation lacking a viable escape route for the victim or a perception of such) can lead to C-PTSD-like symptoms, which include prolonged feelings of terror, worthlessness, helplessness, and deformation of one's identity and sense of self.

Some researchers argue that C-PTSD is distinct from, but similar to PTSD, somatization disorder, dissociative identity disorder, and borderline personality disorder, with the main distinction being that it distorts a person's core identity, especially when prolonged trauma occurs during childhood development . It was first described in 1992 by Judith Herman in her book "Trauma & Recovery" and an accompanying article. Though peer-reviewed journals have published papers on C-PTSD, the category is not yet adopted by either the American Psychiatric Association's (APA) "Diagnostic and Statistical Manual of Mental Disorders", 5th Edition (DSM-5), or in the World Health Organization's (WHO) "International Statistical Classification of Diseases and Related Health Problems", 10th Edition (ICD-10). However, it is proposed for the ICD-11, to be finalized in 2018.

As noted by Altman, McGoey & Sommer, it is important to observe the child, "in multiple contexts, on numerous occasions, and in their everyday environments (home, daycare, preschool)". It is beneficial to view parent and child interactions and behaviors that may contribute to SAD.

Dyadic Parent-Child Interaction Coding System and recently the Dyadic Parent-Child Interaction Coding System II (DPICS II) are methods used when observing parents and children interactions.

Separation Anxiety Daily Diaries (SADD) have also been used to “assess anxious behaviors along with their antecedents and consequences and may be particularly suited to SAD given its specific focus on parent–child separation” (Silverman & Ollendick, 2005). The diaries are carefully evaluated for validity.

At the preschool-aged stage, early identification and intervention is crucial. The communication abilities of young children are taken into consideration when creating age-appropriate assessments.

A commonly used assessment tool for preschool-aged children (ages 2–5) is the Preschool Age Psychiatric Assessment (PAPA). Additional questionnaires and rating scales that are used to assess the younger population include the Achenbach Scales, the Fear Survey Schedule for Infants and Preschoolers, and The Infant–Preschool Scale for Inhibited Behaviors.

Preschool children are also interviewed. Two interviews that are sometimes conducted are Attachment Doll-Play and Emotional Knowledge. In both of the assessments the interviewer depicts a scenario where separation and reunion occur; the child is then told to point at one of the four facial expressions presented. These facial expressions show emotions such as anger or sadness. The results are then analyzed.

Behavioral observations are also utilized when assessing the younger population. Observations enable the clinician to view some of the behaviors and emotions in specific contexts.

Cognitive-behavioral therapy (CBT) is a commonly implemented therapeutic intervention for compulsive hoarding. As part of cognitive behavior therapy, the therapist may help the patient to:

- Discover why he or she is compelled to hoard.

- Learn to organize possessions in order to decide what to discard.

- Develop decision-making skills.

- Declutter the home during in-home visits by a therapist or professional organizer.

- Gain and perform relaxation skills.

- Attend family and/or group therapy.

- Be open to trying psychiatric hospitalization if the hoarding is serious.

- Have periodic visits and consultations to keep a healthy lifestyle.

This modality of treatment usually involves exposure and response prevention to situations that cause anxiety and cognitive restructuring of beliefs related to hoarding. Furthermore, research has also shown that certain CBT protocols have been more effective in treatment than others. CBT programs that specifically address the motivation of the sufferer, organization, acquiring new clutter, and removing current clutter from the home have shown promising results. This type of treatment typically involves in-home work with a therapist combined with between-session homework, the completion of which is associated with better treatment outcomes. Research on Internet-based CBT treatments for the disorder (where participants have access to educational resources, cognitive strategies, and chat groups) has also shown promising results both in terms of short- and long-term recovery.

Other therapeutic approaches that have been found to be helpful are:

1. Motivational interviewing: originated in addiction therapy. This method is significantly helpful when used in hoarding cases in which insight is poor and ambivalence around change is marked.

2. Harm reduction rather than symptom reduction: also borrowed from addiction therapy. The goal is to decrease the harmful implications of the behavior, rather than the hoarding behaviors.

3. Group therapy: reduces social isolation and social anxiety and is cost-effective compared to one-on-one intervention.

4. Eye movement desensitization and reprocessing (EMDR) has been employed, although there is insufficient evidence for EMDR to be considered effective for treating compulsive hoarding (as for treating obsessive-compulsive disorders in general).

Individuals with hoarding behaviors are often described as having low motivation and poor compliance levels, and as being indecisive and procrastinators, which may frequently lead to premature termination (i.e., dropout) or low response to treatment. Therefore, it was suggested that future treatment approaches, and pharmacotherapy in particular, be directed to address the underlying mechanisms of cognitive impairments demonstrated by individuals with hoarding symptoms.

Mental health professionals frequently express frustration regarding hoarding cases, mostly due to premature termination and poor response to treatment. Patients are frequently described as indecisive, procrastinators, recalcitrant, and as having low or no motivation, which can explain why many interventions fail to accomplish significant results. To overcome this obstacle, some clinicians recommend accompanying individual therapy with home visits to help the clinician:

Likewise, certain cases are assisted by professional organizers as well.

Following the DSM-5 work groups’ recommendation to remove the bereavement-exclusionary criteria, there is some concern that the addition of CGD may increase the possibility of medicalizing the grieving process. However, proponents of CGD claim that with proper clinical assessment only those with abnormally incapacitating levels of grief will receive this diagnosis and benefit from treatment. Furthermore, despite the possibility of diagnosis-related stigma the clinical necessity for treatment is a priority for those suffering from CGD.

Emotional dysregulation (ED) is a term used in the mental health community to refer to an emotional response that is poorly modulated, and does not fall within the conventionally accepted range of emotive response.

Possible manifestations of emotional dysregulation include angry outbursts or behavior outbursts such as destroying or throwing objects, aggression towards self or others, and threats to kill oneself. These variations usually occur in seconds to minutes or hours. Emotional dysregulation can lead to behavioral problems and can interfere with a person's social interactions and relationships at home, in school, or at place of employment.

Emotional dysregulation can be associated with an experience of early psychological trauma, brain injury, or chronic maltreatment (such as child abuse, child neglect, or institutional neglect/abuse), and associated disorders such as reactive attachment disorder. Emotional dysregulation may present in people with psychiatric disorders such as attention deficit hyperactivity disorder, bipolar disorder, borderline personality disorder, narcissistic personality disorder, and complex post-traumatic stress disorder. ED is also found among those with autism spectrum disorders. In such cases as borderline personality disorder, hypersensitivity to emotional stimuli causes a slower return to a normal emotional state. This is manifested biologically by deficits in the frontal cortices of the brain.
