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

BACKGROUND

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.

METHOD: 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.

RESULTS

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).

CONCLUSION

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.
