This study investigates the construct validity, composite reliability, and concurrent validity of the Inventory of Attitudes toward Seeking Mental Health Services (IASMHS; Mackenzie, Knox, Gekoski, & Macaulay, 2004). A large sample of Irish police officers (N = 331) participated in the study. Confirmatory factor analysis supported the 3-factor structure of the scale, while composite reliability results demonstrated that the IASMHS possessed excellent internal reliability. Structural equation modelling indicated that help-seeking propensity was the strongest predictor of intentions to engage in psychological counselling followed by psychological openness. Neuroticism was a weak, significant predictor of intentions.Implications of these results are discussed in relation to improving utilization rates of mental health services.
