| pubmed-article:7055277 | pubmed:abstractText | The authors designed a study to identify those independent variables which would statistically discriminate between a group of Viet Nam veterans who were experiencing posttraumatic stress disorder and those who were not. DSM-III criteria for diagnosis were used to measure and operationally define posttraumatic stress disorder. Five variables distinguished between groups: veterans with the disorder reported a negative perception of their family's helpfulness on return home, a higher level of combat, a more immediate discharge after the war, an external locus of control, and a more supportive attitude toward the war before they entered the service. The authors discuss the implications and limitations of these findings. | lld:pubmed |
