The aim of this study was to assess psychometric properties of Parent Irrational Beliefs Scale on parents having children attending secondary school. The research sample comprised of 489 parents (248 mothers and 241 fathers). A Demographic Data Form prepared by the researchers, Irrational Beliefs Scale (IBS) and Dysfunctional Attitute Scale (DAS) were used in order to obtain data. The results of the confirmatory factor analysis showed that Parent Irrational Beliefs Scale having two-factor including 29-items fit the data well enough. To examine the validity of the scale, the correlations between the scores on the expectations subscale of Parent Irrational Beliefs Scale and Dysfunctional Attitude Scale (DAS) (.33), Irrational Belief Scale (IBS) (.24) were assessed. The perfectionism subscale of Parent Irrational Beliefs Scale was correlated with DAS (.62), and IBS-S (.45). The test-retest correlations were .81 for expectations subscale and .71 for perfectionism subscale respectively. Cronbach Alpha internal consistency coefficients were .85 for expectations subscale and .82 for perfectionism subscale. The results obtained from this study demonstrate that Parent Irrational Beliefs Scale is a valid and reliable for assessing irrational beliefs of parents having children attending secondary school.
