The most common instrument used to screen for "probable pathological gambling" behavior is the South Oaks Gambling Screen (SOGS) developed by Lesieur and Blume (1987) at the South Oaks Hospital in New York City. In recent years the use of SOGS has declined due to a number of criticisms, including that it overestimates false positives (Battersby, Tolchard, Thomas & Esterman, 2002).

The "DSM-IV" diagnostic criteria presented as a checklist is an alternative to SOGS, it focuses on the psychological motivations underpinning problem gambling and was developed by the American Psychiatric Association. It consists of ten diagnostic criteria. One frequently used screening measure based upon the DSM-IV criteria is the National Opinion Research Center DSM Screen for Gambling Problems (NODS). The Canadian Problem Gambling Inventory (CPGI) and the Victorian Gambling Screen (VGS) are newer assessment measures. The Problem Gambling Severity Index, which focuses on the harms associated with problem gambling, is composed of nine items from the longer CPGI. The VGS is also harm based and includes 15 items. The VGS has proven validity and reliability in population studies as well as Adolescents and clinic gamblers.

Gambling self-exclusion (voluntary exclusion) programs are available in the US, the UK, Canada, Australia, South Africa, France, and other countries. They seem to help some (but not all) problem gamblers to gamble less often.

Some experts maintain that casinos in general arrange for self-exclusion programs as a public relations measure without actually helping many of those with problem gambling issues. A campaign of this type merely "deflects attention away from problematic products and industries," according to Natasha Dow Schull, a cultural anthropologist at New York University and author of the book "Addiction by Design" who was interviewed for The Fifth Estate (TV series) aired by the Canadian Broadcasting Corporation.

There is also a question as to the effectiveness of such programs, which can be difficult to enforce. In the province of Ontario, Canada, for example, the Self-Exclusion program operated by the government's Ontario Lottery and Gaming Corporation (OLG) is not effective, according to investigation conducted by the television series, revealed in late 2017. "Gambling addicts ... said that while on the ... self-exclusion list, they entered OLG properties on a regular basis" in spite of the facial recognition technology in place at the casinos, according to the Canadian Broadcasting Corporation. As well, a CBC journalist who tested the system found that he was able to enter Ontario casinos and gamble on four distinct occasions, in spite of having been registered and photographed for the self-exclusion program. An OLG spokesman provided this response when questioned by the CBC: "We provide supports to self-excluders by training our staff, by providing disincentives, by providing facial recognition, by providing our security officers to look for players. No one element is going to be foolproof because it is not designed to be foolproof".

Different assessment tools can be used to determine if an individual is addicted to exercise. Most tools used to determine risk for exercise addiction are modified tools that have been used for assessing other behavioral addictions. Tools for determining eating disorders can also show a high risk for exercise addiction.

The Obligatory Exercise Questionnaire was created by Thompson and Pasman in 1991, consisting of 20 questions on exercise habits and attitudes toward exercise and body image. Patients respond to statements on a scale of 1 (never) to 4 (always). This questionnaire aided in the development of another assessment tool, the Exercise Addiction Inventory.

The Exercise Addiction Inventory was developed by Terry "et al" in 2004. This inventory was developed as a self-report to examine an individual's beliefs toward exercise. The inventory is made up of six statements in relation to the perception of exercise, concerning: the importance of exercise to the individual, relationship conflicts due to exercise, how mood changes with exercise, the amount of time spent exercising, the outcome of missing a workout, and the effects of decreasing physical activity. Individuals are asked to rate each statement from 1 (strongly disagree) to 5 (strongly agree). If an individual scores above 24 they are said to be at-risk for exercise addiction.

Since people buying more than they need is usual and accepted, even the most excessive behaviour takes a long time before being considered pathological. Shopping addiction generally manifests between 20–30 years old,

but is not usually detected until several years after, when the addiction has led the person to ruin and bankrupt.

There are usually two stages in coping with the problem. First, people around the addict or the health or social services detect the problem and try to treat it. When, because of the seriousness of the case, it is not possible to solve it in this way, specialised professionals, such as psychologist or psychiatrics, take part. The diagnosis and evaluation of shopping addiction is based on the analysis of confirmed behaviours and their consequences. Specific tests or questionnaires, as the FACC-II (Questionnaire on the psychological aspects of consumer addiction, debt and personal spending habits) are also used. These specific questionnaires or tests are useful in the diagnosis and evaluation of shopping addiction problems, and to drive the therapies in a proper way. FACC-II is one of the most specific and widest. The Edwards Scale is another approach which measures the tendency to compulsively buy. All these resources, as well as personal interviews of the addict and people who surround them, reports and other documents, enable knowledge of when people buy, what they buy and the methods of payment used.

A short 11-question Internet game screen called the BIGS was developed by reSTART to assist in the screening of problematic video game and Internet use.

Screening for problematic use in individuals due the ever-changing digital landscape. Researchers Northrup, Lapierre, Kirk and Rae developers of the Internet Process Addiction Test (IPAT) propose that tools measure different processes utilized over the Internet, such as video game play, social networking, sexual activity and web surfing, may be more helpful than a measure of Internet addiction itself, as the Internet is simply a medium which facilities a variety of interactions, some of which are highly addictive, and others less so.

Some experiences of self-help groups and group therapy have been carried out in a very similar way to those used in other addictions. Preliminary evidence suggests that group for compulsive shoppers colud be effective.>.

Treatment involves becoming conscious of the addiction through studying, therapy, group work, etc...

Research done by Michel Lejoyeux and Aviv Weinstein suggests that the best possible treatment for CB is through cognitive behavioral therapy. They suggest that a patient first be "evaluated for psychiatric comorbidity, especially with depression, so that appropriate pharmacological treatment can be instituted." Their research indicates that patients who received cognitive behavioral therapy over 10 weeks had reduced episodes of compulsive buying and spent less time shopping as opposed to patients who did not receive this treatment (251).

Lejoyeux and Weinstein also write about pharmacological treatment and studies that question the use of drugs on CB. They declare "Few controlled studies have assessed the effects of pharmacological treatment on compulsive buying, and none have shown any medication to be effective" (252). The most effective treatment is to attend therapy and group work in order to prevent continuation of this addiction.

Selective serotonin reuptake inhibitors such as fluvoxamine and citalopram may be useful in the treatment of CBD, although current evidence is mixed. Opioid antagonists such as naltrexone and nalmefene are promising potential treatments for CBD. A review concluded that evidence is limited and insufficient to support their use at present, however. Naltrexone and nalmefene have also shown effectiveness in the treatment of gambling addiction, an associated disorder.

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.

Most research has focused on adult population or on college students, but little is known about epidemiology of behavioral addictions in adolescence. A study conducted by Villella "et al" looked at a group of students and the prevalence of various addictions. His results showed exercise addiction was the second most prevalent, after compulsive buying.

High risk groups that appear to be addicted to exercise include athletes in sports encouraging thinness or appearance standards, young and middle-age women, and young men.

The consequences of oniomania, which may persist long after a spree, can be devastating, with marriages, long-term relationships, and jobs all feeling the strain. Further problems can include ruined credit history, theft or defalcation of money, defaulted loans, general financial trouble and in some cases bankruptcy or extreme debt, as well as anxiety and a sense of life spiraling out of control. The resulting stress can lead to physical health problems and ruined relationships, or even suicide.

The phenomenological similarity and the suggested common basic biological dynamics of kleptomania and OCD, pathological gambling and trichotillomania gave rise to the theory that the similar groups of medications could be used in all these conditions. Consequently, the primary use of selective serotonin reuptake inhibitor (SSRI) group, which is a form of antidepressant, has been used in kleptomania and other impulse control disorders such as binge eating and OCD. Electroconvulsive therapy (ECT), lithium and valproic acid (sodium valproate) have been used as well.

The SSRI's usage is due to the assumption that the biological dynamics of these conditions derives from low levels of serotonin in brain synapses, and that the efficacy of this type of therapy will be relevant to kleptomania and to other comorbid conditions.

Opioid receptor antagonists are regarded as practical in lessening urge-related symptoms, which is a central part of impulse control disorders; for this reason, they are used in treatment of substance abuse. This quality makes them helpful in treating kleptomania and impulse control disorders in general. The most frequently used drug is naltrexone, a long-acting competitive antagonist. Naltrexone acts mainly at μ-receptors, but also antagonises κ- and λ-receptors.

There have been no controlled studies of the psycho-pharmacological treatment of kleptomania. This could be as a consequence of kleptomania being a rare phenomenon and the difficulty in achieving a large enough sample. Facts about this issue come largely from case reports or from bits and pieces gathered from a comparatively small number of cases enclosed in a group series.

Cognitive-behavioural therapy (CBT) has primarily substituted the psychoanalytic and dynamic approach in the treatment of kleptomania. Numerous behavioural approaches have been recommended as helpful according to several cases stated in the literature. They include: hidden sensitisation by unpleasant images of nausea and vomiting, aversion therapy (for example, aversive holding of breath to achieve a slightly painful feeling every time a desire to steal or the act is imagined), and systematic desensitisation. In certain instances, the use of combining several methods such as hidden sensitisation along with exposure and response prevention were applied. Even though the approaches used in CBT need more research and investigation in kleptomania, success in combining these methods with medication was illustrated over the use of drug treatment as the single method of treatment.

Impulse-control disorders have two treatment options: psychosocial and pharmacological. Treatment methodology is informed by the presence of comorbid conditions.

Cash, Rae and Winkler, in a paper titled "Internet Addiction: A brief summary of research and practice", describe early interventions used in the treatment of Internet addiction (IAD), and Internet Gaming Disorder (IGD).

Cognitive Behavior Therapy is designed to help individuals learn how to control their thoughts and feelings. This control is to prevent harmful functions that may trigger impulses to escape into the virtual world. The therapy is setup for three stages. The first stage is to instruct the patient to identify there is a problem and how much a problem computers are creating. Identification is done by using a log to document duration, events, day, of online activity. This can be used to show in black and white how much time is spent online and to help create a realistic goal for patients to strive for. Using this log the patients interact with a therapist to make a schedule for online activity to promote new healthier habits. The second aspect of the treatment program is more for the cognitive aspect, as in, digging into what triggers the excessive online activity. The third phase is to confront or resolve the issues in the patient's life that lead to them seeking escape things via the Internet.

One source states that a major reason the Internet is so appealing is the lack of limits and the absence of accountability.

Professionals generally agree that, for Internet overuse, controlled use is a more practical goal than total abstinence.

Families in the People's Republic of China have turned to unlicensed training camps that offer to "wean" their children, often in their teens, from overuse of the Internet. The training camps have been associated with the death of at least one youth. In November 2009, the government of the People's Republic of China banned physical punishment to "wean" teens from the Internet. Electro-shock therapy had already been banned.

In August 2013, researchers at the MIT Media Lab developed a USB-connected keyboard accessory that would "punish" users – with a small electric jolt – who spent too much time on a particular website.

In July 2014, an internet de-addiction center was started in Delhi, the capital city of India by a non profit organization, Uday Foundation. The Foundation provides counseling to the children and teens with internet addiction disorder.

In August 2009, "ReSTART", a United States-based residential treatment center for "problematic digital media use, internet addiction, and video game addiction", opened near Seattle, Washington, United States. It offers a 7- to 12-week intensive program for adolescents and adults intended to help people set device limits, and address digital distractions.

In 2005, Professor Kiesler called Internet addiction a fad illness. In her view, she said, television addiction is worse. She added that she was completing a study of heavy Internet users, which showed the majority had sharply reduced their time on the computer over the course of a year, indicating that even problematic use was self-corrective.

Formal diagnosis may be performed by a psychologist, psychiatrist, clinical social worker, or other licensed mental health professional. To be diagnosed with OCD, a person must have obsessions, compulsions, or both, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM). The Quick Reference to the 2000 edition of the DSM states that several features characterize clinically significant obsessions and compulsions. Such obsessions, the DSM says, are recurrent and persistent thoughts, impulses or images that are experienced as intrusive and that cause marked anxiety or distress. These thoughts, impulses or images are of a degree or type that lies outside the normal range of worries about conventional problems. A person may attempt to ignore or suppress such obsessions, or to neutralize them with some other thought or action, and will tend to recognize the obsessions as idiosyncratic or irrational.

Compulsions become clinically significant when a person feels driven to perform them in response to an obsession, or according to rules that must be applied rigidly, and when the person consequently feels or causes significant distress. Therefore, while many people who do not suffer from OCD may perform actions often associated with OCD (such as ordering items in a pantry by height), the distinction with clinically significant OCD lies in the fact that the person who suffers from OCD "must" perform these actions, otherwise they will experience significant psychological distress. These behaviors or mental acts are aimed at preventing or reducing distress or preventing some dreaded event or situation; however, these activities are not logically or practically connected to the issue, or they are excessive. In addition, at some point during the course of the disorder, the individual must realize that their obsessions or compulsions are unreasonable or excessive.

Moreover, the obsessions or compulsions must be time-consuming (taking up more than one hour per day) or cause impairment in social, occupational or scholastic functioning. It is helpful to quantify the severity of symptoms and impairment before and during treatment for OCD. In addition to the peron's estimate of the time spent each day harboring obsessive-compulsive thoughts or behaviors, concrete tools can be used to gauge the people’s condition. This may be done with rating scales, such as the Yale–Brown Obsessive Compulsive Scale (Y-BOCS). With measurements like these, psychiatric consultation can be more appropriately determined because it has been standardized.

OCD is sometimes placed in a group of disorders called the obsessive–compulsive spectrum.

When treating addictive personalities, the primary or presenting addiction needs to be treated first. Only once the behavior is under control can the person truly begin to do any of the therapeutic work necessary for recovery.

Common forms of treatment for addictive personalities include cognitive behavioral therapy, as well as other behavioral approaches. These treatments help patients by providing healthy coping skills training, relapse prevention, behavior interventions, family and group therapy, facilitated self-change approaches, and aversion therapy. Behavioral approaches include using positive reinforcement and behavioral modeling. Along with these, other options that help with treating those who suffer with addictive personality include social support, help with goal direction, rewards, enhancing self-efficacy and help teaching coping skills.

Another important skill to learn in treatment, which can be overlooked, is self-soothing. People with addictive personalities use their addictions as coping mechanisms when in stressful situations. However, since their addictions do not actually soothe them, so much as they provide momentary relief from anxiety or uncomfortable emotions, these individuals feel the need to use their addiction more often. Thus, self-soothing and other mindfulness-based interventions can be used for treatment because they provide healthier coping mechanisms once the addictive behavior has been removed. These strategies relate to the use of dialectical behavior therapy, another useful technique. DBT provides ways to tolerate distress and regulate emotions, both of which are challenging to someone with an addictive personality. DBT may not be the most effective treatment for all substance abusers, but there is evidence that it is helpful for most alcoholics and addicts, as well as in eating disorders, and those with co-occurring conditions.

Another form of treatment that has been considered for people with addictive personalities who tend towards substance abuse is medication. A medication called Disulfiram was created in 1947. This pill was used for alcoholics and would cause adverse effects if combined with alcohol. This medication is still used today but two others have been made to help treat alcohol dependence (Acamprosate and Naltrexone). Along with alcohol addictions, Naltrexone is also used for opioid addiction.

Although these medications have proven results in decreasing heavy drinking, doctors still have to consider the patients' health and the risky side effects when prescribing these medications.

Pyromania is best prevented by parents taking the time to educate their children on fire safety and the dangers of fires. Parents should also keep all fire lighting devices out of reach of children and any teenagers to reduce the risk of their starting any fires .

In the case of pathological gambling, along with fluvoxamine, clomipramine has been shown effective in the treatment, with reducing the problems of pathological gambling in a subject by up to 90%. Whereas in trichotillomania, the use of clomipramine has again been found to be effective, fluoxetine has not produced consistent positive results. Fluoxetine, however, has produced positive results in the treatment of pathological skin picking disorder, although more research is needed to conclude this information. Fluoxetine has also been evaluated in treating IED and demonstrated significant improvement in reducing frequency and severity of impulsive aggression and irritability in a sample of 100 subjects who were randomized into a 14-week, double-blind study. Despite a large decrease in impulsive aggression behavior from baseline, only 44% of fluoxetine responders and 29% of all fluoxetine subjects were considered to be in full remission at the end of the study. Paroxetine has shown to be somewhat effective although the results are inconsistent. Another medication, escitalopram, has shown to improve the condition of the subjects of pathological gambling with anxiety symptoms. The results suggest that although SSRIs have shown positive results in the treatment of pathological gambling, inconsistent results with the use of SSRIs have been obtained which might suggest a neurological heterogeneity in the impulse-control disorder spectrum.

Obsessive-compulsive disorders are treated with various serotonergic antidepressants including the tricyclic antidepressant clomipramine and various SSRI medications. With existing drug therapy, OCD symptoms can be controlled, but not cured. Several of these compounds (including paroxetine, which has an FDA indication) have been tested successfully in conjunction with OCD hoarding.

In November 2016, the American Association of Sexuality Educators, Counselors and Therapists (AASECT), the official body for sex and relationship therapy in the United States, issued a position statement on Sex Addiction which states that AASECT "does not find sufficient empirical evidence to support the classification of sex addiction or porn addiction as a mental health disorder, and does not find the sexual addiction training and treatment methods and educational pedagogies to be adequately informed by accurate human sexuality knowledge. Therefore, it is the position of AASECT that linking problems related to sexual urges, thoughts or behaviors to a porn/sexual addiction process cannot be advanced by AASECT as a standard of practice for sexuality education delivery, counseling or therapy."

In 2017, three new USA sexual health organizations found no support for the idea that sex or adult films were addictive in their position statement.

In November 16, 2017 the Association for the Treatment of Sexual Abusers (ATSA) published a position against sending sex offenders to sex addiction treatment facilities. Those centers argued that "illegal" behaviors were symptoms of sex addiction, which ATSA challenged they had no scientific evidence to support.

The appropriate treatment for pyromania varies with the age of the patient and the seriousness of the condition. For children and adolescents treatment usually is cognitive behavioral therapy sessions in which the patient’s situation is diagnosed to find out what may have caused this impulsive behavior. Once the situation is diagnosed, repeated therapy sessions usually help continue to a recovery . Other important steps must be taken as well with the interventions and the cause of the impulse behavior. Some other treatments measures include parenting training, over-correction/satiation/negative practice with corrective consequences, behavior contracting/token reinforcement, special problem-solving skills training, relaxation training, covert sensitization, fire safety and prevention education, individual and family therapy, and medication. The prognosis for recovery in adolescents and children who suffer from pyromania depends on the environmental or individual factors in play, but is generally positive. Pyromania is generally harder to treat in adults, often due to lack of cooperation by the patient. Treatment usually consists of more medication to prevent stress or emotional outbursts in addition to long-term psychotherapy . In adults, however, the recovery rate is generally poor and if an adult does recover it usually takes a longer period of time .

Compulsive talking goes beyond the bounds of what is considered to be a socially acceptable amount of talking. The two main factors in determining if someone is a compulsive talker are talking in a continuous manner, only stopping when the other person starts talking, and others perceiving their talking as a problem. Personality traits that have been positively linked to this compulsion include assertiveness, willingness to communicate, self-perceived communication competence, and neuroticism. Studies have shown that most people who are talkaholics are aware of the amount of talking they do, are unable to stop, and do not see it as a problem.

Some medical systems, including those of at least 15 states of the United States, refer to an Addiction Severity Index to assess the severity of problems related to substance use. According to DARA Thailand, the index assesses potential problems in seven categories: medical, employment/support, alcohol, other drug use, legal, family/social, and psychiatric.

Food addiction impacts relationships, especially those within the family. This is because the person with the addiction is vastly more involved with food than with people – it becomes their safest, most important and meaningful relationship. Other connections to friends and family take a back seat. This often leads to a deep sense of isolation from others.

The naturally occurring sugar inositol has been suggested as a treatment for OCD.

Nutrition deficiencies may also contribute to OCD and other mental disorders. Vitamin and mineral supplements may aid in such disorders and provide nutrients necessary for proper mental functioning.

μ-Opioids, such as hydrocodone and tramadol, may improve OCD symptoms. Administration of opiate treatment may be contraindicated in individuals concurrently taking CYP2D6 inhibitors such as fluoxetine and paroxetine.

Much current research is devoted to the therapeutic potential of the agents that affect the release of the neurotransmitter glutamate or the binding to its receptors. These include riluzole, memantine, gabapentin, N-acetylcysteine, topiramate and lamotrigine.
