Among those with trauma exposure and PTSD symptoms, the group receiving more behaviorally intensive, contingency management treatment had significantly greater reductions in PTSD symptomatology than did the group receiving less\u2010intensive treatment. Regression analyses revealed that greater positive distraction coping and lower negative avoidance coping at baseline, in addition to changes in avoidance coping over the 6\u2010month study period, were significantly related to greater symptom and severity reductions. The study provides some initial evidence of important treatment outcomes other than abstinence in addiction\u2010related interventions.<\/jats:p>","DOI":"10.1002\/jts.20239","type":"journal-article","created":{"date-parts":[[2007,8,25]],"date-time":"2007-08-25T02:22:39Z","timestamp":1188008559000},"page":"565-575","source":"Crossref","is-referenced-by-count":15,"title":["Impact of behavioral contingency management intervention on coping behaviors and PTSD symptom reduction in cocaine\u2010addicted homeless"],"prefix":"10.1002","volume":"20","author":[{"given":"Kristin M.","family":"Lester","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse B.","family":"Milby","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph E.","family":"Schumacher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rudolph","family":"Vuchinich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharina","family":"Person","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olivio J.","family":"Clay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,8,22]]},"reference":[{"key":"e_1_2_1_2_1","volume-title":"Diagnostic and statistical manual of mental disorders","author":"American Psychiatric Association","year":"1994"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/10550490050172227"},{"key":"e_1_2_1_4_1","volume-title":"Cognitive therapy: Basics and beyond","author":"Beck J.
