The purpose of this paper is to provide psychometric data on the Parental Attitudes Toward Psychological Services Inventory (PATPSI), which is a revised measure to assess parents' attitudes toward outpatient mental health services. Using a sample of adults (N = 250), Study 1 supported a 3-factor structure (RMSEA = .05, NNFI = .94, and CFI = .94), adequate internal consistency (ranging from .72 to .92), and test-retest reliability (ranging from .66 to .84). Additionally, results indicated that individuals with previous use of mental health services reported more positive views toward child mental health services. Study 2 provided confirming evidence of the 3-factor structure (NNFI = .94, RMSEA = .08, and the CFI = .95) and adequate reliability (ranging from .70 to .90) using a parent-sample (N = 260). Additionally, discriminate validity of the PATPSI was supported. Implications for research and clinical practice are discussed.
