ABSTRACT
PURPOSE/OBJECTIVE:
This study investigated the psychometric properties of a newly developed Received Social Support Scale for Persons with Serious Mental Illness (rSSS-SMI). The rSSS-SMI measures three support domains Day-to-Day Living support, Mental Health Support, and Adherence Support. RESEARCH METHOD/DESIGN:
(a) to examine the item quality of the rSSS-SMI, (b) to investigate the construct validity and verify the dimensionality of the rSSS-SMI, and (c) to investigate the reliability and validity of the rSSS-SMI scores. A sample of 267 community-based case management service recipients with SMI completed the rSSS-SMI and three additional scales (Interpersonal Support Evaluation List-Short Form [ISEL-12]; Symptom Checklist-6 [SCL-6]; Satisfaction with Life Scale [SWLS]).RESULTS:
Three items were dropped from the scale resulting in a 21-item scale. Confirmatory factor analysis and Item Response Theory analyses revealed our proposed three-factor model fit the data best, with average loadings at .74 (SD = .09). The three-factor model had higher item discrimination and item difficulty parameters than the one-factor model. The rSSS-SMI achieved strong internal consistency with estimates of .94 (full scale), .83 (Day-to-Day Living Support), .84 (Mental Health Support) and .76 (Adherence Support). The three-week interval test-retest reliability coefficient was .59. Convergent and discriminant validity evidence revealed a small, positive correlation between the rSSS-SMI and perceived support (ISEL-12) and symptom distress (SCL-6) and a small, negative, nonsignificant relationship with life satisfaction (SWLS).CONCLUSION:
This study provides preliminary reliability and validity evidence for the rSSS-SMI and confirms our proposed three-factor structure (Day-to-Day Living Support, Mental Health Support, Adherence Support). (PsycInfo Database Record (c) 2022 APA, all rights reserved).
