Cross-cultural adaptation and primary approbation of the Russian version of Posttraumatic Growth and Depreciation Inventory - Expanded version

Abstract

Numerous studies suggest that caring for someone with a chronic disease is often associated with the various negative consequences for the patient's informal caregivers. At the same time, positive changes caused by the stress influence of patient's disease can be also noted. For example, the so-called posttraumatic growth. Currently, there is a lack of assessment tools in domestic psychology, that allow to investigate the relation between constructive (developmental) and destructive aspects of the relative’s mental response in a situation of chronic illness of a loved one.The aim of this work was to carry out cross-cultural adaptation and primary approbation of the Posttraumatic Growth and Depreciation Inventory - Expanded version (PTGDI-X). Primary approbation was performed on a focus group of relatives of patients with cerebral pathology (n = 61, mean age 51,2 [SD = 15,3] years). Convergent and discriminant validity of the PTGDI-X assessed using World Assumption Scale (WAS), Symptom Checklist-90-Revised (SCL-90-R), Level of Relatives’ Emotional Burnout Questionnaire (LREB). In addition, a specially adapted for the research Burden questionnaire was used.The analysis revealed good psychometric characteristics of the PTGDI-X Russian version in terms of: internal subscales consistency (Cronbach’s α coefficients varied from 0,73 to 0,86), internal and external construct validity.
