Examining the reliability and validity of the Turkish version of the Trait Meta-Mood Scale

The aim of the study was to investigate the reliability and validity of the Trait Meta-Mood Scale in a Turkish sample. Trait Meta-Mood Scale (TMMS), The Satisfaction with Life Scale (SWLS), Ruminative Response Scale (RRS), and Beck Depression Inventory (BDI)were administered to 387 (271 females and 113 males) university students with a mean age of 21.77 (SD = 1.65).In the present study, the Turkish model and the original model of TMMS were tested to examine which of the two model yields the better goodness of fit to the Turkish sample. Moreover, internal consistency coefficients were performed to examine the reliability of the original model. The results suggested that the original three-factor model fits the current sample better with valid and reliably scores for Turkish university students. The scale also showed acceptable inter-item reliability and adequate criterion-related validity. Particularly, Clarity of Feelings and Mood Repair were positively correlated with life satisfaction but Attention to Feelings was not. Additionally, rumination was negatively correlated to Clarity of Feelings and Mood Repair, but it was not significantly correlated to Attention to Feelings. Finally, depression was negatively correlated to all subscales of TMMS
