Individuals infected with human immunodeficiency virus (HIV) are at elevated risk for depressive conditions, which in turn can negatively impact health-related behaviours and the course of illness. The present study tested the role of autobiographical memory specificity and its interaction with perceived stress in the persistence of depressive symptoms among dysphoric HIV-positive individuals. Additionally, we examined whether rumination and social problem solving mediated these effects. Results indicated that memory specificity moderated the impact of perceived stress, such that perceived stress was more strongly associated with follow-up depressive symptoms among those with greater memory specificity. Rumination, but not social problem solving, mediated this effect. Implications of these findings are discussed.  相似文献

Reasoning about mechanisms is one of the hallmarks of disciplined inquiry in science and engineering, but comparatively little is known about its precursors and development. Children at grades 2 and 5 predicted and explained the motion of simple mechanical systems composed entirely of visible linkages (levers). Students' explanations of device behavior suggested four forms of knowledge: simple recognition of device components, noting of structural relations among components, construction of cause-effect rules derived by observation of regularities in device behavior, and identification of essential system components and interactions among components that accounted for cause–effect rules. Only a few children coordinated multiple essential components to constitute a mechanistic causal scheme. Mechanistic causal schemes, in turn, were associated with successful prediction of the output motion of a system. Device tracing via gesture and talk appeared to support this form of knowledge development, and hence may inform future instructional design.  相似文献

A service academy military education seeks to develop character. Twenty-four character strengths measured by the Values in Action – Individual Strengths instrument are examined longitudinally to determine effects on character from a service academy education. Significant growth equations were obtained for Citizenship-Teamwork, Hope-Optimism, Fairness, Capacity to Love and be Loved, Appreciation of Beauty, Industry-Perseverance, Zest-Enthusiasm, Spirituality, Creativity, Leadership, Humor-Playfulness, Judgment, and Love of Learning from a mixed models analysis (overall Type 1 error set at .05). Based upon differences expected from a cross-sectional national sample it was inferred that the military college education differentially affected all character strengths except Gratitude, Citizenship-Teamwork, Creativity, Hope-Optimism, Capacity to Love and be Loved, Humor-Playfulness, Perspective, Modesty-Humility, Appreciation of Beauty, and Judgment.  相似文献

Empowerment is an interdisciplinary construct heavily grounded in the theories of community psychology. Although empowerment has a strong theoretical foundation, few context-specific quantitative measures have been designed to evaluate empowerment for specific populations. The present study explored the factor structure of a modified empowerment scale with a cross-sectional sample of 296 women in recovery from substance use who lived in recovery homes located throughout the United States. Results from an exploratory factor analysis identified three factors of psychological empowerment which were closely related to previous conceptualizations of psychological empowerment: self-perception, resource knowledge and participation. Further analyses demonstrated a hierarchical relationship among the three factors, with resource knowledge predicting participation when controlling for self-perception. Finally, a correlational analysis demonstrated the initial construct validity of each factor, as each factor of empowerment was significantly and positively related to self-esteem. Implications for the application of psychological empowerment theory and research are discussed.  相似文献

A multiple group confirmatory factor analysis was used to test the invariance of an attention-deficit/hyperactivity disorder-inattention, attention-deficit/hyperactivity disorder-hyperactivity/impulsivity, oppositional defiant disorder toward adults, academic and social competence five-factor model across of independent groups of Thai adolescents with the Child and Adolescent Disruptive Behavior Inventory (CADBI). Mothers and fathers’ ratings on 872 adolescents were compared to mothers and fathers’ ratings on a different group of 983 adolescents. The design allowed four invariance analyses (i.e., mothers’ ratings of the first group compared to mothers’ ratings of the second group; fathers’ ratings of first group compared to fathers’ ratings of the second group; mothers’ ratings of first group compared to fathers’ ratings of the second group; and fathers’ ratings of first group compared to mothers’ ratings of second group). Support was found for the invariance of like-symptom loadings and symptom intercepts as well as like-factor variances, covariances, and factor means across the four invariance analyses. The findings further expand the construct validity of the CADBI. The paper also introduces a multiple indicators by multiple traits by multiple methods by multiple sources by multiple occasions by multiple groups’ measurement matrix to guide the evaluation of the construct validity of ADHD/ODD rating scales.  相似文献

The objective of this study was to evaluate the efficacy of a couple-tailored print (CTP) intervention on colorectal cancer screening (CRCS), CRCS intentions, and on knowledge and attitudes among couples in which neither partner is on schedule with regard to CRCS. A total of 168 married couples with both members non-adherent with CRCS were randomly assigned to receive either a CTP pamphlet accompanied by a generic print (GP) pamphlet or a GP pamphlet only. Couples completed measures of CRCS, intentions, relational perspective on CRCS, discussions about CRCS, spouse support for CRCS, spouse influence strategies, CRC knowledge, perceived CRC risk, and CRCS benefits and barriers. Results indicated there was no significant benefit of CTP vs. GP on CRCS, but there was a significant increase in CRCS intentions in CTP compared with GP. There was also a significant increase in relationship perspective on CRCS, a significant increase in husbands’ support of their wives’ CRCS, and a significant increase in CRCS benefits in CTP. In summary, CTP did not increase CRCS practices but increased intentions and perceived benefits of CRCS as well as improving couples’ ability to view CRCS as having benefit for the marital relationship.  相似文献

Previous research into face processing in autism spectrum disorder (ASD) has revealed atypical biases toward particular facial information during identity recognition. Specifically, a focus on features (or high spatial frequencies [HSFs]) has been reported for both face and nonface processing in ASD. The current study investigated the development of spatial frequency biases in face recognition in children and adolescents with and without ASD, using nonverbal mental age to assess changes in biases over developmental time. Using this measure, the control group showed a gradual specialization over time toward middle spatial frequencies (MSFs), which are thought to provide the optimal information for face recognition in adults. By contrast, individuals with ASD did not show a bias to one spatial frequency band at any stage of development. These data suggest that the “midband bias” emerges through increasing face-specific experience and that atypical face recognition performance may be related to reduced specialization toward optimal spatial frequencies in ASD.  相似文献

Abstract

Participants (N = 101) scoring high or low on a new scale for assessing fear of dissociative sensations (Dissociation Sensitivity Index) underwent an audio/visual sensory challenge using a device called the D.A.V.I.D. Participants' report of subjective fear and level of dissociation were measured before and after completing the audio/visual sensory challenge. Consistent with prediction, participants scoring high on the DSI responded to the challenge with significantly greater increases in subjective fear and dissociative symptoms relative to those scoring low on the DSI. Contrary to prediction, the DSI performed poorer than the Anxiety Sensitivity Index in predicting participants' response to the audio/visual sensory challenge. Theoretical and clinical implications of the findings are discussed.  相似文献

Abstract

Stress, coping, and appraisal were explored in order to better understand the factors associated with smoking cessation. Employees from 61 worksites received one of three programs which incorporated the use of self-help manuals, incentives, social support groups, and cognitive-behavioral techniques. Results indicated successful quitters perceived less stress in their lives, used more problem-focused coping and less emotion-focused coping, and perceived more control over their stressors than participants who were not able to quit smoking.  相似文献

Subitizing, the fast and accurate enumeration of up to about 3 or 4 objects, has often been thought to be dependent on limited-capacity preattentive mechanisms. We used an attentional blink paradigm to investigate the extent to which subitizing requires attentional resources. On each trial, subjects identified a target letter in an RSVP stream and then enumerated dots presented in the stream that were either simultaneous with the target letter or followed it by up to 400 ms. For numerosities from 2 to 9, evidence of an attentional blink was observed; only enumeration of 0 or 1 elements was independent of lag. Thus, even enumeration of 2–3 objects, which is within the traditional subitizing range, appears to require attentional resources. The relation of this work to studies on the attentional requirements of detecting a unique item among distractors, a supposedly preattentive discrimination, is briefly discussed.  相似文献
