Received Social Support Scale for Persons With Mental Illness: Psychometric Properties, Validity and Reliability of the Turkish Version

This methodological study aimed to assess the validity and reliability of the Received Social Support Scale for Persons with Mental Illness (rSSS-MI), developed by Chronister et al. (2022), by adapting it into Turkish. The study consisted of 274 people who applied to the psychiatry outpatient clinic of a state hospital between April 2023 and April 2024. Data were collected using a Personal Information Form, the Received Social Support Scale for Persons with Mental Illness, and the Multidimensional Scale of Perceived Social Support. The Turkish version of the rSSS-MI demonstrated a 3-factor structure consisting of 21-items, and the items' factor loadings ranged from 0.82 to 0.96. The goodness of fit indices were χ2/df = 3.335, GFI = 0.823, NFI = 0.933, TLI = 0.944, IFI = 0.952, CFI = 0.952, RMSEA = 0.092, and SRMR = 0.024. Additionally, Cronbach's alpha coefficient of the rSSS-MI was calculated as 0.98, and item-total score correlation coefficients were between 0.80 and 0.92. These findings indicate that the Turkish version of the rSSS-MI is a valid and reliable measurement tool.
