Reliability and validity of Turkish version of stress resilience item bank 10 item short form

The aim of this study was to adapt the Stress Resilience Item Bank 10-Item Short Form, originally developed in German, into Turkish for patients diagnosed with psychosomatic disorders, and to evaluate its psychometric properties, validity, and reliability.

The study included 507 patients aged 18-65 years whose conditions were historically categorized under psychosomatic disorders and who were diagnosed with Mental Factors Affecting Other Medical Conditions according to DSM-5 criteria, along with 74 healthy controls. Sociodemographic data were collected using a structured data form completed by patients and, when applicable, their relatives. Participants completed the Stress Resilience Item Bank 10-Item Short Form, the Connor-Davidson Resilience Scale, the Brief Resilience Scale, and the ICD-10 Symptom Rating Scale.

The mean age of the patients was 45.9 ± 15 years, and 74.2% were female. In the reliability analysis, Cronbach's alpha was 0.79. Test-retest reliability indicated a high correlation between the two measurements (r = .675, p < .001). In validity analyses, exploratory factor analysis yielded a two-factor structure explaining 49.2% of the total variance. Confirmatory factor analysis supported this structure, with acceptable model fit indices (RMSEA = 0.062, CFI = 0.942, GFI = 0.962). The Stress Resilience Item Bank 10-Item Short Form showed significant correlations with the Connor-Davidson Resilience Scale and the Brief Resilience Scale (r = .73, p < .001; r = .67, p < .001, respectively).

The Stress Resilience Item Bank 10-Item Short Form, has been identified as a suitable, valid, and reliable measurement tool for use in the Turkish patient population with psychosomatic disorders, the majority of whom are women.
