Summary
This study confirms the reliability of a social support scale for measuring material, emotional, informational, affective, and social interaction dimensions. The instrument is suitable for assessing social support
Area of Science:
- Psychometrics
- Occupational Health
- Social Sciences
Context:
- Assessing social support is crucial for understanding employee well-being.
- Reliability of measurement tools is essential for valid research outcomes.
- The Pro-Health Study in Rio de Janeiro requires validated instruments.
Purpose:
- To evaluate the test-retest reliability of a social support scale.
- To determine the internal consistency and stability of five social support dimensions.
Summary:
- A scale measuring five dimensions of social support (material, emotional, informational, affective, positive social interaction) was administered to 192 university employees twice, 15 days apart.
- Reliability was assessed using intraclass correlation coefficient (ICC), weighted kappa, and log-linear models, with internal consistency evaluated by Cronbach's alpha.
- Results indicated adequate reliability (ICC: 0.78–0.87) and high internal consistency (Cronbach's alpha: 0.75–0.93), with no significant variations across demographic groups.
Impact:
- The validated social support scale can be reliably used in the Pro-Health Study.
- Findings support the use of this instrument for assessing social support's association with health in occupational settings.
- Establishes a dependable tool for future research on social support and health-related outcomes.
