although trichotillomania may , at first sight , often impress as an apparently inexplicable persistent habit , further analysis shows that this symptom often develops in a climate of psychosocial stress in the family , e.g. , hospitalizations of child or mother , the additional stress inherent in moving to a new house , or developmental problems such as sibling rivalry , inability to focus activities and play in the younger child , and school problems in the older child .
