Background and Objectives: The social support deterioration model (SSDM) posits that individuals who do not receive adequate support following a disaster are vulnerable to losses in community solidarity and perceived support, as well as the development of persistent distress. However, limited longitudinal research has evaluated the relations among support and these outcomes among disaster-affected individuals. Design: The current study utilized random intercept cross-lagged panel modeling (RI-CLPM) to examine reciprocal relations among received support, community solidarity, perceived support, and posttraumatic stress disorder (PTSD) symptoms among rural Hurricane Florence survivors (n = 261) assessed 5-8 months post-hurricane (T1), and then at two more timepoints at three-month intervals (T2 and T3). Results: Results of the RI-CLPM supported that lower received support at T2 was associated with decreases in community solidarity at T3, and higher perceived support at T1 was associated with increases in received support at T2. In supplemental analyses, higher received support at T2 was associated with lower PTSD symptoms at T3. Conclusions: Consistent with the SSDM, individuals who receive less support post-disaster are vulnerable to losses in community solidarity and potentially persistent PTSD symptoms. Conversely, those with stronger support networks may be better able to access needed support in the longer-term.
