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.

Approximately 1 to 5% of school-aged children have school refusal, though it is most common in 5- and 6-year olds and in 10- and 11-year olds, it occurs more frequently during major changes in a child’s life, such as entrance to kindergarten, changing from elementary to middle school, or changing from middle to high school. The problem may start following vacations, school holidays, summer vacation, or brief illness, after the child has been home for some time, and usually ends prior to vacations, school holidays, or summer vacation, before the child will be out of school for some time. School refusal can also occur after a stressful event, such as moving to a new house, or the death of a pet or relative.

The rate is similar within both genders, and although it is significantly more prevalent in some urban areas, there are no known socioeconomic differences.

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.
