Validity and reliability study of the Turkish version of the Bipolar recovery questionnaire in Bipolar affective disorder
Abstract
The aim of this study was to assess the validity and reliability of the Turkish versions of the Bipolar Recovery Questionnaire (BRQ) and to examine the clinical variables associated with personal recovery. This was a single-center cross-sectional study. Outpatients with the diagnosis of Bipolar I Disorder (BD I) were included in the study. The BRQ was translated from English into Turkish and back-translated into English. Internal consistency was assessed using Cronbach’s alpha, corrected item-total correlations, and Cronbach’s alpha if item deleted. Structured Clinical Interview for DSM-5,Clinical Version (SCID-5/CV), administered by the clinician, was used to confirm the diagnosis BD I. Subjective Recovery Assessment Scale (SubRAS), Personal and Social Performance Scale (PSP) and Global Assessment of Functioning (GAF) were used to examine convergent validity. The clinician-administered Hamilton Depression Rating Scale (HAM-D) and Young Mania Rating Scale (YMRS) were used to evaluate symptom severity in patients. Multivariable regression analysis was performed to evaluate the clinical variables associated with BRQ total scores. Cronbach’s alpha coefficient for BRQ was 0.888 and showed very good internal consistency. Corrected item-total score correlation coefficients ranged from − 0.114 to 0.742. Total BRQ score had moderate positive correlations with PSP (ρ = 0.432 , p < 0.001) and SubRAS (ρ = 0.383, p < 0.001), a weak positive correlation with GAF (ρ = 0.304 , p = 0.004), and a weak negative correlation with the HAM-D total score (ρ = -0.301 , p = 0.004). A weak positive correlation was observed between the total score of BRQ and the total duration of education (ρ = 0.265 , p = 0.012). Multivariable regression analysis showed that having a university degree was associated with higher BRQ scores compared with the reference education category. The present study provides preliminary evidence supporting the reliability and validity of the Turkish version of the BRQ for assessing personal recovery in individuals with BD I.
