The aim of this study was to test the confirmatory factor structure and validation of the Parent-Adolescent Conflict Questionnaire in a nonclinical sample of 13 to17 year old adolescents. The study was descriptive and cross-sectional. Seven hundred and forty eight students were selected from the high schools of Qods (a district of Tehran province) by multistage random sampling. The participants completed the Parent-Adolescent Conflict Questionnaire (Adolescent Form; Asadi Younesi, 2011), the Children's Perceptions of Inter parental Conflict Scale (Grych, Seid, & Fincham, 1992), the Youth Self-report (Achenbach, 1991)), the Family Communication Scale (Olson, 1995), and the Family Satisfaction scale (Barnes & Olson, 1985). The results of confirmatory factor analysis supported the fourteen-factor of the Parent-Adolescent Conflict Questionnaire. To investigate divergent and criterion validity, the Pearson correlation coefficient was used. The results indicated that the correlation of the Parent-Adolescent Conflict Questionnaire with the other instruments of the study were between 0.21 and 0.57.These results were more satisfactory for the intensity of the conflict part of the parent-adolescent conflict questionnaire than for the frequency part of the questionnaire. The Cronbach alpha coefficient was 0.97 for the frequency of the parent-adolescent conflict and was 0.96 for the intensity of parent- adolescent conflict. The test-retest coefficients were 0.76 and 0.75 for the frequency of parent- adolescent conflict and the intensity of the parent-adolescent conflict, respectively. The findings suggest that the Parent-Adolescent Conflict Questionnaire have good psychometric properties and can be used in research settings and family counseling in Iran.
