  1. No Reported SI includes either “No” or “Don’t Know” responses; it does not include subjects who did not respond. Bold cells are those significant by post hoc test. NS: p-value greater than 0.05. Self-injurious behavior indicates presence or absence of common behaviors associated with PWS, such as skin picking, nail pulling, rectal digging, etc. Unknown includes both “Don’t know” and no answer. Diagnosis questions only asked if symptom question answered yes. Cramer’s V: Measure of Association (Effect size ranging 0 to 1)
