Distress tolerance (DT), the perceived or actual ability to tolerate negative emotional or physical states, is inversely related to posttraumatic stress disorder (PTSD) symptoms in civilian, community samples. No studies to date have examined the relationship between DT and PTSD in clinical samples of veterans with a comorbid diagnosis of PTSD and a substance use disorder (SUD). Thus, the present study examined the relationship between DT and PTSD in a sample of predominately African American, male veterans (n = 75) diagnosed with comorbid PTSD and SUD (according to a structured clinical interview). Results of hierarchical linear regression models indicated that DT was inversely related to total PTSD symptom severity score, above and beyond depressive symptoms and SUD severity. Of the 4 symptom clusters, DT was inversely associated with intrusions and hyperarousal. These findings are discussed in light of previous work with civilian samples. Determining whether treatment incorporating DT skills would be useful for veterans undergoing PTSD treatment should be evaluated. 相似文献
The present study examined the flexibility with which people can adopt different category schemes in the spatial domain. In
a location memory task, participants viewed and estimated the locations of four kinds of objects that were spatially grouped
by object identity. This identity-based arrangement was either congruent or incongruent with the perceptually based, geometric
categories that have been reported in previous research. Four experiments examined the conditions under which these different
category schemes are used to inform estimates of locations. The results showed that use of identity information depended on
the number of objects to be remembered during a trial: When one or two objects were remembered at a time, only geometric categories
affected estimates, but when four objects were to be remembered, both geometric categories and identity groupings affected
estimates. As memory load increases, participants rely on additional sources to inform their estimates of location. 相似文献
Interpersonal problems are significant markers of personality disorders (PDs). There is little research examining the specific interpersonal problems which lead to social impairment in PD. This study used canonical correlation analyses to examine the relationship between interpersonal competence and PDs, first as categorized by DSM-IV diagnoses, then as categorized by empirically-derived factors, in a sample at risk for recurrence of major depression. The most significant sources of shared variance were social inhibition and self-disclosure competence. The empirically-derived PD categories accounted for more variance in interpersonal competence than the DSM-IV diagnostic categories. Social skills training in initiation and self-disclosure may be useful for treating individuals with PD who experience interpersonal problems. Empirically-derived categories of PD symptoms may capture interpersonal problems experienced by individuals with PD which DSM-IV categories do not. 相似文献
The authors tested the cognitive vulnerability hypotheses of depression with a retrospective behavioral high-risk design. Individuals without current Axis I diagnoses who exhibited either negative or positive cognitive styles were compared on lifetime prevalence of depressive and other disorders and the clinical parameters of depressive episodes. Consistent with predictions, cognitively high-risk participants had higher lifetime prevalence than low-risk participants of major and hopelessness depression and marginally higher prevalence of minor depression. These group differences were specific to depressive disorders. The high-risk group also had more severe depressions than the low-risk group, but not longer duration or earlier onset depressions. The risk group differences in prevalence of depressive disorders were not mediated by current depressive symptoms. 相似文献
Women have been active in the American Psychological Association (APA) almost from the beginning. In general, however, they did not attain high-level office, editorships, and significant committee posts at the same level as their male counterparts. During one 51-year period, for example, no women were elected to the APA presidency. Despite protests, little changed. Finally, in the 1970s, the climate in the APA shifted. The Committee on Women in Psychology was formed, as was the APA Division of the Psychology of Women. From then on, women's issues have remained an important concern of the association. 相似文献
Apathy is common in HIV, separable from depression, and has been associated with non-adherence to antiretroviral therapy (ART). We examined the associations between apathy and critical psychological determinants of ART adherence, as per the information-motivation-behavioral model, in 85 persons living with HIV. Apathy was measured using a composite of the apathy subscale of the Frontal Systems Behavioral Scale and the vigor-activation scale of the Profile of Mood States. Independent of major depressive disorder, apathy was related at small-to-medium effect sizes with motivation to adhere and self-efficacy for health-related decision-making and medication management, but not with HIV knowledge or medication management skills. These findings suggest that apathy plays a unique role in several critical health adherence determinants and support the importance of assessment and management of apathy to maximize health outcomes among individuals with HIV disease.
To inform ethical procedures for human subjects research using mobile health (mHealth), we examined perceived risks and benefits of study participation among emerging adults (N = 54) with drug use who completed text message assessments of substance use and sexual behaviors. Most participants reported comfort with participation and some reported perceived benefits, such as improved relationships. Perceived risks were infrequently reported, including negative emotions and legal or financial concerns. In conclusion, participants from a vulnerable population reported few perceived harms of participation in longitudinal mHealth assessments of sensitive behaviors. Researchers should continue characterizing participants’ perspectives on ethical aspects of mHealth research. 相似文献
