Psychometric Properties of the Three Dimensional Meaning in Life Scale (3DM) among Turkish-Speaking Adults
Abstract
Previous research supports the tripartite framework of meaning in life (MiL). The Three Dimensional Meaning in Life Scale (3DM) is a self-report measure drawing upon the tripartite framework. 3DM includes coherence, purpose, and significance. The primary goal of the present research was to evaluate the psychometric properties of the Turkish version of the 3DM, and to assess how 3DM and its subscales relate to mental health and psychopathology indicators in a Turkish-speaking adult sample. The present research recruited a sample of 702 participants (Female = 540). Confirmatory factor analysis, measurement invariance analyses, Pearson’s correlation tests, reliability analyses, regression analyses, and independent samples t-tests were utilized. The first-order confirmatory factor analysis confirmed that the Turkish version replicated the 11-item three-factor structure of the 3DM: [(χ2= 181, df =40, p =.00)], CFI = .98, TLI = .97, RMSEA = .071, 90%CI[.060, .081], SRMR = 0.03. Internal consistency coefficients of the subscales and the 3DM total showed strong reliability with strong item-total correlations. The correlation coefficients of the 3DM supported concurrent and divergent validity. The 3DM predicted well-being and psychopathology indicators. Measurement invariance analyses of the subscales demonstrated that coherence, purpose, and significance scales were consistent and equivalent across gender. The results indicate that the Turkish version of the 3DM is a valid and reliable scale when administered among adult Turkish-speaking people.
