Posttraumatic stress after a motor vehicle accident: a six-month follow-up study utilizing latent growth modeling.

Features of posttraumatic stress disorder (PTSD) for 596 survivors of motor vehicle accidents were examined by self-report measures at 1 week, 1 month, 3 months, and 6 months after the motor vehicle accident (MVA). Latent growth modeling was utilized to study the trend and predictors of the level of distress. Results indicated that 5-20% of the participants reported to have a significant level of posttraumatic stress in one, two, or three of the PTSD symptom clusters within the period studied. Survivors with significant acute stress 1 week after the MVA had a higher risk for developing chronic posttraumatic stress. Although the severity of intrusive and hyperarousal symptoms decreased over time, the severity of avoidance symptoms remained unchanged. Factors predicting the course of PTSD after an MVA are identified.

Psychological responses to outbreak of severe acute respiratory syndrome: a prospective, multiple time-point study.

This study examined anxiety and coping responses to the outbreak of severe acute respiratory syndrome (SARS) in Hong Kong. Trait anxiety, situation-specific coping strategies, and coping flexibility were proposed as predictors of state anxiety during the early phase of the SARS epidemic. Seventy-two Hong Kong undergraduates (31 men, 41 women) participated in a prospective, multiple time-point study. Participants' trait anxiety and coping flexibility had been assessed in an earlier study. Five months later, they reported their anxiety and coping at each of the four time points during the outbreak. Results revealed fluctuations in state anxiety across time points. Results from hierarchical linear modeling showed that trait anxiety as well as the situation-appropriate coping strategies of avoidance and personal hygiene practice accounted for changes in state anxiety.

Cognitive processes underlying coping flexibility: differentiation and integration.

This study investigates how individuals formulate flexible coping strategies across situations by proposing differentiation and integration as two stress-appraisal processes. Results showed that participants who coped more flexibly adopted the dimensions of controllability and impact in differentiating among different stressful situations. They also deployed an integrated strategy: the deployment of more monitoring in situations perceived as controllable but less of this strategy in situations perceived as uncontrollable. Participants who coped less flexibly did not adopt any given dimensions and tended to use more monitoring regardless of situational characteristics. These results suggest that individuals with different extents of coping flexibility differ in the cognitive processes. Individuals who cope more flexibly display a greater extent of differentiation and integration than do those who cope less flexibly. These findings are translated into strategies for stress management workshops.
