This analysis examined chronic medical problems as a risk factor for depressive symptomatology using longitudinal survey data from a sample of rural Tennesseans. Two waves of data (1977 and 1983) were collected on 532 rural Middle-Tennessee residents. An initial investigation found chronic medical problems a powerful predictor of depression. Furthermore, internal and external resources (personal resources and social support) operated as moderating factors between the stress of medical problems and psychiatric impairment. Panel regression analyses indicated that Time 1 depression level as well as medical problems at Time 2 (t2) were significant predictors of depression at t2 in rural areas of the mid-South. Finally, the buffering effects of both social support and personal resources were explored. 相似文献

The basis of judgment by laypersons in the self-evaluation of difficulties with anger control is examined. Responses to a set of 10 specific criteria of anger control problems and a self-rating of degree of problem were obtained on 190 subjects. The criteria and problem ratings were found to have satisfactory testretest reliability. Stepwise multiple regression analysis showed that certain criteria entered more than others into the self-judgments of anger control problems. Exploratory factor analysis produced three factors, interpreted as Personal Difficulties with Anger, Aggression, and Hostility, which replicated some of the previous research. Implications of the findings for a social constructivist view of self-judgment of anger and aggression and the development of self-report instruments are discussed. Additional studies with other samples are suggested. 相似文献

I wish to thank Peter Hylton, from whom I have learned much in discussion of these issues, and whose comments upon a previous draft of this paper helped to give it its present shape. I must also thank two anonymous referees, who were most helpful on both specific and general points, and Axel Boldt, who helped with the German. 相似文献

CHRONIC NOISE AND PSYCHOLOGICAL STRESS 总被引:1,自引:0,他引:1
Abstract— This article illustrates the value of incorporating psychological principles into the environmental sciences Psycho physiological, cognitive, motivational, and affective indices of chronically exposed to aircraft noise We demonstrate for the first time that chronic noise exposure is associated with elevated neuroendocnne and cardiovascular measures, muted cardiovascular reactivity to a task presented under acute noise, deficits in a standardized reading test administered under quiet conditions, poorer long-term memory, and diminished quality of life on a standardized index Children in high-noise areas also showed evidence of poor persistence on challenging tasks and ambulation to auditory distraction on a signal-to-noise task They reported considerable annoyance with community noise levels, as measured utilizing a calibration procedure that adjusts for individual differences in rating criteria for annoyance judgments 相似文献

Data are summarized from 152 single-subject analyses of the reinforcing functions of self-injurious behavior (SIB). Individuals with developmental disabilities referred for assessment and/or treatment over an 11-year period were exposed to a series of conditions in which the effects of antecedent and consequent events on SIB were examined systematically by way of multielement, reversal, or combined designs. Data were collected during approximately 4,000 experimental sessions (1,000 hr), with the length of assessment for individuals ranging from 8 to 66 sessions (M = 26.2) conducted over 2 to 16.5 hr (M = 6.5). Differential or uniformly high responding was observed in 145 (95.4%) of the cases. Social-negative reinforcement (escape from task demands or other sources of aversive stimulation) accounted for 58 cases, which was the largest proportion of the sample (38.1%). Social-positive reinforcement (either attention or access to food or materials) accounted for 40 (26.3%) of the cases, automatic (sensory) reinforcement accounted for 39 (25.7%), and multiple controlling variables accounted for 8 (5.3%). Seven sets of data (4.6%) showed either cyclical or inconsistent patterns of responding that were uninterpretable. Overall results indicated that functional analysis methodologies are extremely effective in identifying the environmental determinants of SIB on an individual basis and, subsequently, in guiding the process of treatment selection. Furthermore, an accumulation of assessment data from such analyses across a large number of individuals provides perhaps the most rigorous approach to an epidemiological study of behavioral function. 相似文献

We evaluated the feasibility of local school personnel conducting functional analysis and reinforcement-based treatment procedures within actual classroom settings. Following an initial in-service workshop on functional assessment and differential reinforcement procedures, on-site technical assistance was provided two to four times per month to local school personnel working in transdisciplinary teams. Overall results suggest that local school personnel were able to implement all procedures adequately with periodic technical assistance. In addition, functional analysis was effective in identifying individual maintaining contingencies, the derived treatments were effective, and the results were maintained throughout the approximate 18 months of this investigation. 相似文献

Thirty-two 10-month-olds completed an habituation procedure where a male or female face was paired with a specific object. Results reveal 10-month-olds can form categories based on correlations among attributes of social information. Basic processes involved in gender role formation are present in 10-month-olds. 相似文献

Meta-monitoring has been defined as a secondary feedback system in which people monitor their rates of progress in attaining their primary self-regulatory goals. The purpose of this study was to explore the effects of adding an explicit version of meta-monitoring to a long-term cognitive-behavioral treatment program for obesity. It was expected that meta-monitoring in this therapeutic context might increase positive affect and, thereby, improve self-regulated cognitive and behavioral changes. Four obese women who were in treatment for 1 to 2 years prior to the study served as subjects. They meta-monitored by rating their self-monitoring, affect, and eating and thinking patterns for each of 34 weeks. Weight changes and measures of self-monitoring, affect, and eating/thinking patterns suggested some initially positive effects (during the first 2 weeks, especially). While the duration of the impact of meta-monitoring in this clinical trial seemed modest, the approach may have promise as a means of reenergizing self-regulatory efforts during lapses or slumps. Experiments on various methods of operationalizing meta-monitoring, examining its effects on different problems, and testing its hypothesized mechanisms seem warranted. 相似文献
