The tripartite model of anxiety and depression: symptom structure in depressive and hypertensive patient groups 总被引:2,自引:0,他引:2
Marshall GN Sherbourne CD Meredith LS Camp P Hays RD 《Journal of personality assessment》2003,80(2):139-153
The structure of self-reported symptoms representative of the tripartite model was examined using data drawn from the Medical Outcomes Study (Tarlov et al., 1989). Participants were persons who had been diagnosed 48 months previously as suffering from either depression (N = 315) or hypertension (N = 403). Results of confirmatory factor analyses were broadly consistent with the tripartite model (L. A. Clark & Watson, 1991). Factors emerged corresponding to each of the 3 posited first-order dimensions of negative affect, positive affect, and physiologic arousal. Nonetheless, some discrepancies were found between the observed data and the hypothesized tripartite model. First, the obtained physiologic arousal factor was best viewed as reflecting nonspecific somatic distress rather than physiologic arousal. Finally, although differentiable in the strictest statistical sense, all three domains were significantly correlated (.36 to.86, absolute value). In particular, contrary to the tripartite model, positive and negative affect covaried markedly (-.81 to -.86). Findings raise issues concerning the utility of the tripartite model as a heuristic framework for enhancing understanding of individual differences in normal mood as well as mood disorders. 相似文献

Women perform better than men on tests of verbal memory, but the nature of this advantage has not been precisely established. To examine whether phonemic memory is a factor in the female advantage, we presented, along with other verbal memory tasks, one containing nonsense words. Overall, there was the expected female advantage. However, an examination of the individual tests showed female superiority in recall of the real words but not the nonsense words. 相似文献

The safety and efficacy of medications for preventive treatment of migraine is the subject of current concern and investigation in health care. Two single-center, double-blind, placebo-controlled studies were conducted to evaluate the efficacy and safety of topiramate for migraine prophylaxis. Seventy patients with a diagnosis of migraine were randomly assigned to topiramate-treated and placebo groups. The studies consisted of a 4-week baseline phase, a 6-8 week titration, and 8-12 weeks of maintenance. Topiramate was titrated from an initial dose of 25 mg/day to a target dose of 100 mg BID. The primary efficacy measure, the mean 28-day migraine frequency, was lower in topiramate-treated patients than in the placebo group (3.2 versus 3.8, P=.001). Similarly, topiramate treatment resulted in a significantly greater mean reduction in migraine frequency than did placebo (1.55 versus 0.47, P=.001) and a significantly higher responder rate (35.3% versus 8.3%, P=.008). Paresthesia was the most common side effect reported with topiramate treatment. Other topiramate-associated adverse events included altered taste, memory impairment, diarrhea, and appetite suppression/weight loss. The rates of discontinuation were similar for the topiramate group (n=10) and the placebo group (n=8). These results suggest that topiramate is effective and well tolerated in the preventive treatment of migraine headaches. 相似文献

As many as one in five women worldwide will be sexually assaulted over the course of her lifetime (United Nations 2008), yet myths that downplay the prevalence and severity of sexual assault are still widely accepted. Are myths about sexual assault (rape myths) more likely to be accepted in cultures that endorse more traditional gender roles and attitudes toward women? To explore the relationships among rape myth acceptance, attitudes toward women, and hostile and benevolent sexism, data were collected from 112 Indian and 117 British adults, samples from two cultures differing widely in their gender role traditionalism. Analyses confirmed a cultural difference in rape myth acceptance, with the more traditional culture, India, accepting myths to a greater extent than the more egalitarian culture, Britain. Indian participants’ greater rape myth acceptance was explained by their more traditional gender role attitudes and hostile sexism. We discuss ways in which promoting gender egalitarianism may help to break down negative beliefs and reduce the stigma surrounding sexual assault, especially in India, for example through interventions which increase exposure to women in less traditional roles (e.g., those in positions of power). 相似文献

In order to better integrate research on personality pathology, interpersonal problems, and social skills, we applied the traditional methods of these three research strands (questionnaires, interviews, and interpersonal role-plays) to the same sample. Participants who attributed higher levels of interpersonal problems to themselves in general were also more critical of their own role-play performances, but these impressions were not mirrored by observer-ratings. Self-observer agreement in judging overall role-play performance was essentially zero. Interviewer-ratings of personality pathology had incremental validity over self-ratings in predicting observer-rated role-play performance. Self-reports of interpersonal functioning leave relevant behavioral variance untapped and thus should be complemented by other sources of information. 相似文献
