Post-traumatic stress disorder in primary-care settings: prevalence and physicians' detection.

BACKGROUND: Little is known about the prevalence of PTSD in primary-care settings and regarding the ability of primary-care physicians to detect PTSD. The current study examines prevalence of PTSD in a national sample of primary-care attenders and primary-care physicians' detection of PTSD and general psychological distress in PTSD patients. METHODS: Data are from a national study of 2975 primary-care attenders in Israel. Demographic data, responses to the GHQ-28, PTSD Inventory and physicians' diagnoses were examined. RESULTS: Twenty-three per cent of all patients who attended clinics (N = 684) reported traumatic events, 39% of whom (males 37%, females 40%) met criteria for PTSD on the PTSD Inventory. Eighty per cent of the males and 92% of the females with PTSD were distressed according to the GHQ. According to physicians, 37% of persons who reported trauma (40% of the women, 32% of the men) suffered from psychological distress. Only 2% of patients meeting PTSD criteria on the self-report measure were given a diagnoses of PTSD by physicians. CONCLUSIONS: Many primary-care patients suffer from PTSD, which is usually accompanied by major psychological distress. Attention by primary-care physicians to a history of trauma could improve physicians' detection of this disabling disorder.

Does a threat appeal moderate reckless driving? A terror management theory perspective.

A series of two studies examined the effects of threat appeals on reckless driving from a terror management theory perspective. In both studies, all the participants (N = 109) reported on the relevance of driving to their self-esteem, and, then, half of them were exposed to a road trauma film and the remaining to a neutral film. In Study 1, the dependent variable was the self-report of intentions to drive recklessly in hypothetical scenarios. In Study 2, the dependent variable was actual behavior (driving speed) in a driving simulator. Findings indicated that a road trauma film led to less reported intentions of reckless driving, but to higher driving speed than a neutral film. These effects were only found among participants who perceived driving as relevant to their self-esteem. The discussion emphasized the self-enhancing mechanisms proposed by the terror management theory.

The impact of mortality salience on reckless driving: a test of terror management mechanisms.

A series of 4 studies, based on terror management theory (TMT), examined the effects of mortality salience on risk taking while driving. In all the studies, participants (N = 603) reported on the relevance of driving to their self-esteem. Then half of them were exposed to various mortality salience inductions, and the remaining to a control condition. The dependent measures were either self-reported behavioral intentions of risky driving or driving speed in a car simulator. In Study 4, half of the participants in each condition received positive feedback about their quality of driving. Findings showed that mortality salience inductions led to more risky driving than the control condition only among individuals who perceived driving as relevant to their self-esteem. The introduction of positive feedback about driving eliminated this effect. The results were discussed in light of the self-enhancing mechanisms proposed by TMT.
