Validity and Reliability of Turkish Version of the Balanced Index of Psychological Mindedness

The purpose of current study was to explore psychometric properties of the Turkish version of the Balanced Index of Psychological Mindedness (BIPM). Studies regarding psychological mindedness (PM) are still limited in Turkey; and there are few valid instruments to measure PM. The Turkish version of the BIPM and the 20-Item Toronto Alexithymia Scale (TAS) was administered to 654 voluntary undergraduate students. Confirmatory factor analysis indicated a good fit for the model including two subscales (interest and ability dimensions of PM) with a total of 14 items (x2/df = 3.11, p < .001, RMSEA = 0.060, S-RMR = 0.059, GFI = 0.95, AGFI = .0.93, CFI = 0.94). McDonald’s Omega (ω) for scores on the overall scale was .85, .73 for scores on the Interest Subscale and .76 for scores on the Insight Subscale. Test–retest reliability coefficients were found as .61 for the scores on the BIPM total score, .55 for scores on the Interest subscale and .56 for scores on the Insight subscale (p < .01). As expected, the BIPM total scale score were negatively correlated with TAS total score (r = -.59).
