Evaluating a Parent-Focused Privacy, Bodily Autonomy, and Personal Safety Education: Effects on Knowledge and Affective Outcomes

Children with neurodevelopmental disabilities may need explicit, developmentally appropriate support regarding bodily autonomy, privacy, consent, and personal safety. This randomized pretest-posttest controlled study evaluated a six-session parent-focused module situated within comprehensive sexuality education. Sixty parents were assigned to intervention or wait-list control groups. Knowledge gains were significantly greater in the intervention group, although a posttest ceiling limited interpretation of effect magnitude. Subscale analyses showed a significant group-by-time effect for anxiety, reflecting lower anxiety in the intervention group. The attitude interaction did not remain significant after Holm adjustment, and no differential change was detected for self-efficacy. The findings indicate immediate gains in knowledge-test scores and a reduction in reported anxiety but do not establish behavioral change, maintenance, scalability, or policy effectiveness.
