A pseudophobia is a purported irrational aversion or fear whose existence is as yet unproven. Examples of this type of condition include schoolphobia and separation anxiety. The term has also been applied to first time fathers and mothers who have an exorbitant fear of hurting their own infant child due to an exaggerated perception of their fragility. John Bowlby has described the agoraphobic condition as a pseudophobia. These features may in actuality encompass a reaction to a lack of a secure refuge or other underlying pathological processes. Its origin typically derives from some dreaded memory.

Certain children who are particularly attached to their mother or other family figure due to separation anxiety and/or attachment theory often suffer the onset early, in pre-school, crèche or before school starts.

School phobia is diagnosed primarily through questionnaires and interviews with doctors. Other methods like observation have not proven to be as useful. This is partly because (school) anxiety is an internal phenomenon. An example of a modern multidimensional questionnaire is the "Differential Power Anxiety Inventory 'approach, with twelve scales to diagnose four different areas: anxiety-inducing conditions, manifestations, coping strategies and stabilization forms."

- Cognitive and lifestyle exploration

School refusal is the refusal to attend school due to emotional distress. School refusal differs from truancy in that children with school refusal feel anxiety or fear towards school, whereas truant children generally have no feelings of fear towards school, often feeling angry or bored with it instead. Children's Hospital Boston provides a chart showing the difference between the school refusal and truancy.

Besides calling it School Refusal, it can also be called schooliophobia, school phobia was coined by a former editor. Schooliophobia is coined as all phobias are derived from Greek. In such cases, School in Greek is σχοείο. The term "school refusal" was coined to reflect that children have problems attending school for a variety of different reasons and these reasons might not be the expression of a true phobia, such as separation or social anxiety.
