Anxiety is the most pervasive childhood mental health disorder today. This study examined the parent component of a school-based universal prevention and early intervention program. Participating parents (N = 122) completed four measures on anxiety, the Anxiety Sensitivity Index, the Center for Epidemiological Studies-Depression, the Penn State Worry Questionnaire, and the Screen for Child Anxiety Related Emotional Disorders, before and after the parent program. The effectiveness of the program was investigated by analysing mean scores of the parent self-reported anxiety symptoms and parent reports of child anxiety symptoms. The main analyses conducted were 2 × 2 between-within ANOVAs for each measure. The hypothesis that parents who participated in the program (n = 20) would report reduced anxiety symptoms for themselves and for their children when compared to parents who did not attend (n = 120) was not confirmed. The parent's satisfaction level with the program was also studied, with high acceptability ratings providing strong social validity for this program. Implications of the findings, strengths, limitations and suggestions for further research are discussed.
