This study examined posttraumatic stress (PTS) and posttraumatic growth (PTG) among 226 Tibetan refugees across two generations. Additional objectives were to (i) examine the sex and generation differences on the scores of trauma, PTS, and PTG, (ii) explore the relationship between traumatic experiences, PTS and PTG, and (iii) investigate the mediating effect of cognitive-emotional regulation strategies between the traumatic experiences and PTS as well as PTG. Females scored higher on trauma, PTS, and PTG. The trauma, PTS, and PTG scores of the two generations were significantly different. Acceptance and putting into perspective partially mediated the relationship between traumatic experience and PTS. Positive refocusing, refocus on planning, putting into perspective, and catastrophisizing partially mediated the relationship between traumatic experiences and PTG. © 2011 Wiley Periodicals, Inc.
