Patients indicated that they made less use of the defense mechanism of principalization than control subjects. No other differences between patients and controls were significant. Platelet 5-HT concentration was positively correlated with the subjectively reported anxiety. Plasma norharman concentration was negatively correlated with the defense mechanisms of principalization and repression and positively correlated with coping strategies involving palliation. The positive correlations of norharman levels with projection and self-comforting fell short of significance and existed in the patient group only. No correlation was apparent between levels of plasma norharman and scores on anxiety. It was concluded that norharman is not a marker for panic disorder or trait anxiety, but that it might reflect intrapsychic and coping processes.<\/jats:p>","DOI":"10.2466\/pr0.1997.80.1.51","type":"journal-article","created":{"date-parts":[[2011,8,31]],"date-time":"2011-08-31T14:34:59Z","timestamp":1314801299000},"page":"51-59","source":"Crossref","is-referenced-by-count":2,"title":["Trait Anxiety, Coping with Stress, and Norharman"],"prefix":"10.1177","volume":"80","author":[{"given":"Ren\u00e9","family":"Verheij","sequence":"first","affiliation":[{"name":"Section Pathophysiology of Behavior, Erasmus University Rotterdam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leo","family":"Timmerman","sequence":"additional","affiliation":[{"name":"Delta Psychiatric Hospital, Poortugaal, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Passchier","sequence":"additional","affiliation":[{"name":"Department of Medical, Psychology and Psychotherapy, Erasmus University Rotterdam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Durk","family":"Fekkes","sequence":"additional","affiliation":[{"name":"Section Pathophysiology of Behavior, Erasmus University Rotterdam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lolke","family":"Pepplinkhuizen","sequence":"additional","affiliation":[{"name":"Section Pathophysiology of Behavior, Erasmus University Rotterdam"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1997,2,1]]},"reference":[{"key":"bibr1-pr0.1997.80.1.51","first-page":"190","volume":"59","author":"Airaksinen M.
