We present PTSD-trajectories of resilience, delayed onset, recovery, and chronicity.•We investigate the predictive role of locus of control and coping style related to membership of these trajectories.•Internal locus of control decreases the risk of belonging to the symptomatic trajectories.•Less use of emotion-focused coping decreases the risk of symptomatic trajectory membership.•Less use of problem-focused coping increases the risk of membership of symptomatic trajectories. While longitudinal posttraumatic stress responses are known to be heterogeneous, little is known about predictors of those responses. We investigated if locus of control (LOC) and coping style are associated with long-term PTSD-trajectories after exposure to combat. Six hundred and seventy five Israeli soldiers with or without combat stress reaction (CSR) from the Lebanon war were assessed 1, 2, and 20 years after the war. Combat exposure, LOC, and coping style were then investigated as covariates of the trajectories of resilience, recovery, delayed onset, and chronicity. Symptomatic trajectories in the CSR and the non-CSR group were significantly associated to varying degrees with perceived life threat during combat (ORs: 1.76–2.53), internal LOC (0.77–0.87), emotional coping style (0.28–0.34), and low use of problem-focused coping (2.12–3.11). In conclusion, assessment of LOC and coping can aid prediction of chronic PTSD outcomes of combat exposure.
