Psychometric Properties of the Positive Mental Health Scale (PMH-Scale) Among Turkish University Students

Abstract

Abstract. Background: The PMH-scale is a person-centered, brief and psychometrically sound scale measuring positive mental health. Considering the practicality of the scale and the good psychometric properties reported previously, the adaptation of the PMH-scale to Turkish may provide professionals and researchers a beneficial tool to assess well-being. Aims: This study was designed to investigate the psychometric properties of the Positive Mental Health Scale among Turkish university students by utilizing a cross-sectional correlational survey model. Method: For the adaptation of the scale, different validity and reliability tests were performed. Confirmatory factor analysis was run for construct validity. Convergent validity was assessed by examining relations of the scale with Life Orientation Test, Short Depression-Happiness Scale, Depression Anxiety Stress Scale, and General Self-Efficacy Scale. Reliability was assessed with internal consistency and composite reliability. Measurement invariance across genders was tested through Structural Equation Modelling. Results: Validity and reliability analyses provided satisfactory results. Results of confirmatory factor analysis revealed that current data fit the original unidimensional model. Besides, measurement invariance analysis provided validity evidence in terms of gender invariance. Limitations: Findings of the present study were limited to university students, most of whom were female. Conclusion: In conclusion, the Turkish Positive Mental Health Scale was found to be valid and reliable in the sample of university students.
