Opposing results have been interpreted as resulting from methodological differences between studies.We investigated the diurnal profile of salivary cortisol in a population of highly traumatized adult males from Rwanda with and without PTSD, who spent the whole day of examination together under amaximally standardized schedule. Besides the detection of PTSDrelated alterations in cortisol release we aimed at determining physiologically relevant effects of cumulative trauma exposure on HPA functioning in interaction with or independent of diagnosis. There were no differences in the diurnal pattern of cortisol release between subjects with and without PTSD. We observed an increasing prevalence of PTSD with increasing number of different traumatic event types experienced, replicating earlier results on a building-block effect of multiple traumatization. However, size of cumulative exposure was not related to any of the cortisol measures. The results suggest that besides methodological constraints also confounding factors not previously controlled for, e.g., sex differences or current life stress, might contribute to the diverging results of lowered, unchanged or enhanced cortisol secretion in PTSD. Future research should therefore closely monitor these possible confounds to optimize models for cortisol in research on stress-dependent illnesses.</dcterms:abstract> <dc:contributor>Elbert, Thomas</dc:contributor> <dc:contributor>Kolassa, Stephan</dc:contributor> <dcterms:issued>2009</dcterms:issued> <dc:contributor>Kolassa, Iris-Tatjana</dc:contributor> <dc:creator>Elbert, Thomas</dc:creator> <dc:creator>Engler, Harald</dc:creator> <dc:language>eng</dc:language> <dcterms:bibliographicCitation>First publ. in: Psychoneuroendocrinology ; 34 (2009), 4. - S. 523-531</dcterms:bibliographicCitation> <dc:format>application/pdf</dc:format> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/10998"/> <dc:creator>Riether, Carsten</dc:creator> <dc:contributor>Eckart, Cindy</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-25T09:24:37Z</dcterms:available> <dcterms:title>No PTSD-related differences in diurnal cortisol profiles of genocide survivors</dcterms:title> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
