Measurement and mismeasurement of mood: recurrent and emergent issues 总被引:12,自引:0,他引:12
The affective explosion in psychology has led to tremendous advances in mood measurement. Mood ratings reflect a hierarchical structure consisting of two broad dimensions-Positive Affect and Negative Affect-and multiple specific states. Brief scales have been developed that reliably assess Positive and Negative Affect across different populations and time frames, in both between- and within-subject data. We examine controversies related to (a) the content of these higher order scales and (b) the independence of Positive and Negative Affect. Regarding the latter, we show that Positive and Negative Affect scales remain largely independent across a wide range of conditions, even after controlling for random and systematic error. Finally, there remains little consensus regarding the lower order structure of affect. This lack of a compelling taxonomy has substantially slowed progress in assessing mood at the specific affect level. 相似文献

An apparatus was developed to study social reinforcement in the rat. Four Long-Evans female rats were trained to press a lever via shaping, with the reinforcer being access to a castrated male rat. Responding under a fixed-ratio schedule and in extinction was also observed. Social access was found to be an effective reinforcer. When social reinforcement was compared with food reinforcement under similar conditions of deprivation and reinforcer duration, no significant differences were observed. 相似文献

The influence of subject and interviewer characteristics on the reliability of self-reports of alcohol consumption among young adults was investigated. Data were gathered from black and white college students of both sexes (N's=24) using a time-line procedure. The results snowed that these young adults provided highly reliable self-reports regarding their use of alcohol. Test-retest correlations for a criterion interval of 90 days were .96, .93, and .97 for the numbers of abstinent, moderate-drinking, and heavy-drinking days, respectively. Analyses also showed that white female subjects generally provided more reliable reports of abstinent and heavy-drinking days and that white female interviewers gathered more reliable reports across the three drinking disposition categories. These findings suggest that nonalcoholic young adults' retrospective reports of their drinking behavior can be reliably assessed using the time-line methodology. Future research is required to determine the validity of these self-reports and to understand the differential influence of subject and interviewer characteristics on the levels of reliability found. 相似文献

Factor analyses were carried out on the responses of 115 cigarette smokers to the Smoking Questionnaire of Russell et al. (1974), to the Situational Smoking Questionnaire of Frith (1971) and to certain items of a biographical smoking questionnaire. In the analysis of Russell's questionnaire, a set of six factors was extracted, bearing some resemblance to the six factors found by the authors of the questionnaire, although the matching of factors was by no means perfect. However, the results did support Russell et al.'s finding of a major dimension of degree of dependence upon cigarettes, together with an orthogonal factor contrasting pharmacological with non-pharmacological dependence. The analysis of the Situational Smoking Questionnaire confirmed Frith's finding that the first principal component represented a general desire for cigarettes while the second contrasted desire to smoke in high- and low-arousal inducing (or stressful and relaxing) situations; and these two components corresponded fairly well with the first two components extracted from Russell's questionnaire, pharmacological dependence being associated with smoking in stressful situations. 相似文献

An adaptive psychometric procedure that places each trial at the current most probable Bayesian estimate of threshold is described. The procedure takes advantage of the common finding that the human psychometric function is invariant in form when expressed as a function of log intensity. The procedure is simple, fast, and efficient, and may be easily implemented on any computer. 相似文献

Previous research has suggested that left-handedness relates to delinquency and violence. In an effort to pinpoint the nature of this apparent relationship, we compared the MMPIs of 72 left- and 687 right-handed men 60 yr. old or less on an alcohol treatment ward. No significant differences appeared. The results are compared to earlier research and hypotheses for further research are suggested. 相似文献

Tripartite model of anxiety and depression: psychometric evidence and taxonomic implications 总被引:58,自引:0,他引:58
We review psychometric and other evidence relevant to mixed anxiety-depression. Properties of anxiety and depression measures, including the convergent and discriminant validity of self- and clinical ratings, and interrater reliability, are examined in patient and normal samples. Results suggest that anxiety and depression can be reliably and validly assessed; moreover, although these disorders share a substantial component of general affective distress, they can be differentiated on the basis of factors specific to each syndrome. We also review evidence for these specific factors, examining the influence of context and scale content on ratings, factor analytic studies, and the role of low positive affect in depression. With these data, we argue for a tripartite structure consisting of general distress, physiological hyperarousal (specific anxiety), and anhedonia (specific depression), and we propose a diagnosis of mixed anxiety-depression. 相似文献
