Attitudes is a key help-seeking construct that influences treatment seeking behavior via intention to seek help, per the theory of planned behavior (TPB). This article presents the development and psychometric evaluation of the Mental Help Seeking Attitudes Scale (MHSAS), designed to measure respondents' overall evaluation (unfavorable vs. favorable) of their seeking help from a mental health professional. In Study 1 (N = 857 United States adults), exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and item response theory (IRT) analysis were used to identify an optimal set of 9 items that demonstrated initial evidence of internal consistency, unidimensionality, and strong measurement equivalence/invariance (ME/I) across gender, past help-seeking experience, and psychological distress. Initial convergent evidence of validity was demonstrated via theoretically anticipated relationships between the MHSAS and key variables in the help-seeking nomological network (e.g., subjective norms, perceived behavioral control, intention, public stigma, self-stigma, anticipated risks and benefits, gender, previous help seeking). Initial incremental evidence of validity was demonstrated when the MHSAS demonstrated the ability to account for unique variance in help-seeking intention, beyond that accounted for by the Attitudes Toward Seeking Professional Psychological Help-Short Form scale (ATSPPH-SF) and the Psychological Openness subscale of the Inventory of Attitudes Toward Seeking Mental Health Services (IASMHS-PO). Study 2 (N = 207 United States adults at Times 1 and 2) provided initial evidence of test-retest reliability over a 3-week period. The MHSAS offers mental health professionals a new tool for measuring attitudes that may avoid limitations of current help seeking-attitudes measures (e.g., construct-irrelevant variance).

A theory of MHL can guide future researchers to clearly delineate important constructs and their interrelationships. For practitioners, a theory of MHL can help inform how to improve MHL at both the individual and community level.

People's intention to seek help from a mental health professional is thought to be the proximal cause of help-seeking behavior and thus is a dependent variable frequently measured by help-seeking researchers. Using a research design that accounted for actual future help-seeking behavior, the present study documented the dimensionality, internal consistency, and predictive evidence of validity of 3 intention instruments: the Intentions to Seek Counseling Inventory (ISCI), General Help Seeking Questionnaire (GHSQ), and Mental Help-Seeking Intention Scale (MHSIS). The sample was composed of 405 community-dwelling adults who self-identified as currently experiencing a mental health concern. Results provided support for the ISCI's 3-factor structure and the internal consistency of its 3 subscale scores. In contrast, the GHSQ did not demonstrate clear evidence of adequate measurement model fit or internal consistency in the present sample. Results also tentatively suggested that the 3-item MHSIS is a unidimensional instrument that produces an internally consistent total score with appropriate construct replicability. The ability of these instruments to predict who would seek help from a mental health professional in the next 3 months was also examined. The MHSIS demonstrated the strongest evidence of predictive validity (about 70% of participants were correctly classified), followed by the GHSQ and ISCI. (PsycINFO Database Record
