İki Boyutlu Yas Ölçeği’nin Türkçe Formunun Geçerlik ve Güvenirlik Çalışması

SUMMARY Objective: The aim of this study was to determine the reliability and validity of the Turkish version of Two-Track Model of Bereavement Questionnaire (TTBQ-T) (Rubin et al 2009), a 70-item questionnaire for comprehensively evaluating the process of bereavement. Materials and Methods: The questionnaire was initially translated from English into Turkish, and then back translated. Subsequently, it was administered to 205 bereaved individuals that lost a significant other within the last 5 years. In order to assess the questionnaire’s construct validity the Beck Depression Inventory (BDI) and the Impact of Event Scale-Revised (IES-R) were also administered to the participants. The factor structure, reliability, and test-retest reliability of TTBQ-T were evaluated. Results: Factor analysis yielded results that were, for the most part, similar with those yielded by the original study; however, there were some cross loading items that yielded a 5-factor solution (Relational active grieving, Close and positive relationship with the deceased, Traumatic perception of the loss, Conflictual relationship with the deceased and Social dysfunction). Cronbach’s alpha coefficients for these 5 factors were 0.91, 0.88, 0.82, 0.78, and 0.65, respectively. In order to determine if the responses were loaded under 2 tracks, a higher order factor analysis was conducted. The relationships between BDI and IES-R, and TTBQ-T total scores were examined in order to determine the construct validity of TTBQ-T. The present findings indicate that TTBQ-T has construct validity. Conclusions: The findings indicate that TTBQ-T is a reliable and valid questionnaire for use in Turkey. The findings are discussed in the light of the literature.
