Validation of a Multi-Dimensional Social Support Measure for Individuals Who Are Incarcerated

Purpose: This study sought to validate the psychometric properties of the Network Composition Survey (NCS), a multi-dimensional conceptualization of social support for individuals who are incarcerated. Methods: Data included 1,539 individuals recruited in 50 prisons across four states to participate in the pilot trial of a prison reentry program. Exploratory factor analysis using the first support person data identified a factor structure, and confirmatory factor analysis verified that structure using the second and third support person data conducted with Mplus 8.2. Results: Two of the hypothesized dimensions, informational and emotional support, were confirmed, and a third factor of companionship was identified. Conclusion: The reduced NCS is a reliable and valid measure of multi-dimensional social support for individuals during incarceration. The NCS reflects a more nuanced assessment of the complexities of interpersonal dynamics with support figures. The NCS also provides utility services targeted for social support during reentry.
