Abstract In social cognitive theory, perceived self-efficacy to exercise control over potential threats plays a central role in anxiety arousal. Threat is a relational property reflecting the match between perceived coping capabilities and potentially hurtful aspects of the environment. People who believe they can exercise control over potential threats do not engage in apprehensive thinking and are not perturbed by them. But those who believe they cannot manage threatening events that might occur experience high levels of anxiety arousal. Experimental analyses of the microrelation between perceived self-efficacy and anxiety arousal reveal that perceived coping inefficacy is accompanied by high levels of subjective distress, autonomic arousal and catecholamine secretion. Environmental events are not always completely under personal control and most human activities contain some potential risks. The exercise of control over anxiety arousal, therefore, requires not only development of behavioral coping efficacy but also efficacy in controlling dysfunctional apprehensive cognitions. It is not frightful cognitions per se but the perceived self-inefficacy to turn them off that is the major source of anxiety arousal. Analyses of the causal structure of self-protective behavior show that anxiety arousal and avoidant behavior are mainly co-effects of perceived coping inefficacy. 相似文献

Abstract Stress has been operationalized in numerous ways across studies of physical and mental health, raising questions about the appropriate definition of stress and the construct validity of stress measures. The present paper discusses the theoretical and operational strengths of three prominent approaches to stress definition and then attempts to integrate them into a comprehensive and robust multidimensional definition of stress. In a study of socioeconomically disadvantaged pregnant women, structural equation modelling techniques were used to test whether a single latent construct underlies environmental, perceptual, and response-based indicators of stress. Results suggested a two-factor, rather than a single-factor, model of stress. Stress perception and emotion were part of a single underlying latent factor, a phenomenological stress construct, whereas environmental conditions in the form of major life events represented a second and distinct component of stress. Failure to find a single latent stress construct is interpreted as evidence for the importance of individual perception or appraisal as a mediator of response to difficult environmental conditions. The findings suggest that multidimensional models of stress are theoretically justified and that enhancement of stress measurement in this manner may enable researchers to better identify health effects of stress. 相似文献

Abstract This study examined discrepancies between subjective and objective measures of state anxiety as a function of test anxiety in undergraduates. Under evaluative stress conditions, state anxiety was assessed in terms of (a) self-reported cognitive and somatic anxiety, (b) behavioral reactivity (motor and facial tension, avoidance comments and avoidance of eye contact), (c) physiological arousal (heart rate and skin resistance), and (d) cognitive and motor task performance. Participants high in test anxiety showed disproportionately greater self-reported than objective state anxiety. In contrast, those low in test anxiety showed lower self-reported than objective anxiety. The high- and the low-test-anxiety groups differed only in self-reported emotional reactivity. In line with current cognitive theories of anxiety, overestimation of reactivity in high-test anxiety, as well as underestimation in low-test anxiety, are conceptualized as a hypervigilance bias and an avoidance bias, respectively, in processing internal cues, i.e., prioritization and inhibition of attention to one's own behavioral and physiological signs of distress. 相似文献

Abstract It is suggested that worry has not been given serious academic attention due to problems of definition, and a prevailing belief that it is an unnecessary addition to the theorists vocabulary given the term “anxiety”. However, an increasing awareness of the importance of cognitive factors in emotional disorders makes the study of worry a necessary endeavour. Furthermore, inclusion of worry in DSM III-R as the principle diagnostic index of Generalised Anxiety Disorder has given the term clinical credibility. Three theoretical approaches to the subject of worry are considered: the test anxiety literature, which has focused on the effects of worry on performance, and two largely clinical accounts, a tripartite theory of worry and anxiety proposed by Borkovec, Metzger, and Pruzinsky (1986), and the model of anxious apprehension proposed by Barlow (1988). All approaches are critically evaluated, and suggestions made for future formulations. 相似文献

Abstract This study examined the proposition that the efficacy of social support depends upon situational and personality variables. Specifically, it was hypothesized that women high on trait anxiety or undergoing their first experience of childbirth, would profit more from the presence of the husband during delivery than women low on trait anxiety or who had previously given birth. One hundred and twenty new mothers were asked to rank the level of state anxiety, state anger, tension and pain they had experienced during childbirth. Changes in their blood pressure and the amount of tranquilizing medication they had received were also measured. Results obtained with negative affectivity measures almost fully confirmed the hypotheses. Hypotheses regarding blood pressure were confirmed in part, but no support was found when using pain level and amount of tranquilizing medication as dependent variables. The findings are discussed in relation to the stress-buffering hypothesis and the manner in which trait anxiety might mediate the relationship between level of social support and individuals' stress reactions. 相似文献

The interaction model of anxiety was examined by assessing both state and trait anxiety in 64 male military personnel on a Basic Parachutist Course. Two separate tests of the interactional model of anxiety were conducted, involving physical danger and social evaluation situations. The same subjects participated in both studies. In both physical danger and social evaluation studies, measures of state anxiety and cognitive appraisal (perception) of anxiety were obtained in both high-stress and non-stress conditions. Measures of social evaluation and physical danger trait anxiety were obtained in a low-stress condition. The interactional model was strongly supported for the physical danger situation. As predicted, high physical danger trait anxiety subjects experienced greater increases in state anxiety than low physical danger subjects proceeding from the non-stress to the high stress physical danger condition. The interaction model was not supported in the social evaluation situation; although not significant, mean levels of state anxiety were in the predicted direction. Results are discussed in the context of person perception and the need for testing personality models in realistic field settings. 相似文献

Abstract This study examined the role of social support in the relationship between work demand and psychological distress (GHQ 12) in correctional officers (N=419), a high stress occupational group. Work demands were positively associated with strain. There was no evidence that social support buffered the negative impact of work demands. Rather, consistent with most previous research findings, support showed direct benefits and these were discussed in the context of worker participation and control. The hypothesis that officers high in negative affectivity, as measured by trait anxiety would show greater reactivity to work demands was not supported. However, trait anxiety appeared to inflate the relationship between work stressors (work demand and work support) and psychological distress supporting recent suggestions that the role of trait anxiety in occupational stress should not be disregarded. Trait anxiety combined additively with work demand to predict individual differences in psychological distress, however social support moderated the impact of trait anxiety on strain. 相似文献

Abstract The hypothesis that domain-specific self-related cognitions (self-concept of own competence and control orientations) are predictors of text anxiety in students is tested by longitudinal data. At the beginning and at the end of a school year the following variables were measured twice in a sample of 346 secondary school students (grades six to ten): (1) self-concept of own competence in mathematics, (2) three aspects of locus of control for problem-solving behavior (internality, powerful others control, and chance control), (3) generalized locus of control of reinforcement, (4) test anxiety as well as manifest anxiety. The cross-sequential developmental gradients point toward symmetries in the development of self-related cognitions and test anxiety. The results of cross-lagged correlation analyses show that the null hypothesis (no causal relations exist between the self-related cognitions and test anxiety) can be rejected for the domain-specific aspects of (a low) self-concept of own competence and locus of control (low internality and high chance control), which are confirmed as preceding test anxiety. However, longitudinal results also show that findings of cross-sectional studies tend to overestimate the relations between self-related cognitions and test anxiety in a developmental perspective. 相似文献

The focus of this study was to investigate the consistency of observed overt behaviors, psychophysiological measures, and reported cognitions in high and low socially anxious psychiatric patients. Forty-seven psychiatric patients (25 high and 22 low socially anxious ones) were exposed to two situations: the initiation of a conversation and the refusal of a request. For both groups of subjects, consistency across situations (Situations) and trait indicators (Reactions) was highest for psychophysiological measures. Observed overt behaviors showed the lowest consistency across Situations and Reactions. Substantial evidence was found for the consistency of Persons x Situations and Persons x Reactions interactions. Moreover, high socially anxious subjects showed a higher consistency than low socially anxious patients with respect to observed overt behaviors and reported cognitions. Using psychophysiological measures, low socially anxious patients showed higher consistency than high socially anxious subjects. The implications for the assessment of social anxiety are discussed. 相似文献

To ascertain whether psychiatric outpatients can be classified into distinct types according to their self-reported symptoms of anxiety, the Beck Anxiety Inventory (BAI) was administered to 655 outpatients diagnosed with DSM-III-R anxiety disorders. Cluster analysis identified three internally consistent subscales representing subjective, somatic, and panic symptoms. Further analysis revealed six types of outpatients reflecting below average, panic-subjective, low subjective, low somatic-panic, above average, and subjective-somatic anxiety. The types were differentiated with respect to age, primary diagnosis, clinically rated anxiety, and both self-reported and clinically rated depression. 相似文献
