The current study aimed to explore sleep habits, maternal psychological symptoms, and other risk factors in children with childhood masturbation (CM). The study was conducted with 80 children with CM and 44 children as a control group. Sleep habits were assessed with the Children's Sleep Habits Questionnaire and mothers' psychiatric symptoms were screened using the Symptom Checklist-90. In the CM group, sleeping in the same room with parents, history of unplanned pregnancy, and not playing with the child every day were more common than in the control group. Sleep problems (in particular, night waking) are associated with increased incidence of CM. The simple act of parents playing with their children every day may protect against children engaging in CM. Maternal psychiatric symptoms were more common among children with CM than in the control group. By expanding our knowledge about potential risk factors associated with CM, clinicians can distinguish between desirable and undesirable behavior and intervene in pathological cases.
