Please see Table 1 for descriptive statistics and zero-order correlations. PTS symptom severity was significantly positively related to marijuana use coping motives (r = .37, p < .01), and significantly negatively related to DT (r = −.47, p < .01). Furthermore, DT was significantly negatively related to marijuana use coping motives (r = −.37, p < .01). PTS symptom severity was also significantly related to marijuana use expansion motives (r = .24, p < .01), while DT levels were not significantly related to marijuana use expansion motives (r = .11, p > .01). Overall, only the marijuana use coping motives variable was significantly related to both PTS and DT levels.
