An educational intervention increased knowledge and self-efficacy for pediculosis prevention in mothers, indicating effective strategies for head lice management.
This study investigates the impact of an educational intervention based on the Health Belief Model (HBM) on mothers of elementary school girls suffering from head lice infestations in Fasa, Iran. A total of 80 mothers were randomly assigned to either an intervention group or a control group. The intervention included a structured educational programme delivered via WhatsApp, focusing on HBM constructs such as perceived sensitivity, severity, benefits, cues to action, and self-efficacy. Data collected through a validated questionnaire revealed a significant increase in knowledge and preventive behaviours among mothers in the intervention group compared to the control group (p ≤ 0.001). The effect size was large (Cohen’s d = 0.99), indicating a substantial impact of the intervention. Furthermore, students whose mothers participated showed a 95% improvement in managing head lice. The findings suggest that targeted education for mothers can enhance protective behaviours against head lice in their daughters.
