Introduction     
A dynamic model of affect suggests that positive and negative affect (PA and NA) are normally relatively independent of one another, whereas the heightened apprehensiveness and narrowed cognitive attention in persons with anxiety may contribute to a more unidimensional affect structure. This possibility was examined in a sample of 230 patients seeking treatment for anxiety and depressive disorders in the Netherlands. Two methods, a multiple-group confirmatory factor analysis (CFA) and Fisher's z test of correlations, were used to test these predicted relationships within a sample of persons diagnosed with either a depressive or an anxiety disorder. Both methods supported these predictions, with the depressed group exhibiting relatively independent PA and NA while the anxious group's affects were more strongly inversely correlated.  相似文献

Social anxiety is theorised to arise from sustained over-activation of a mammalian evolved system for detecting and responding to social threat with corresponding diminished opportunities for attaining the pleasure of safe attachments. Emotional forecasting data from two holidays were used to test the hypothesis that greater social anxiety would be associated with decreased expectations of positive affect (PA) and greater anticipated negative affect (NA) on a holiday marked by group celebration (St. Patrick's Day) while being associated with greater predicted PA for daters on a romantic holiday (Valentine's Day). Participants completed symptom reports, made affective forecasts and provided multiple affect reports throughout each holiday. Higher levels of social anxiety were associated with greater anticipated PA for Valentine's Day daters, but lower experienced PA on the holiday; this was not found for trait anxiety and depression. Alternatively, trait anxiety, depression and social anxiety were associated with less predicted PA for St. Patrick's Day, greater anticipated NA and diminished experienced PA/greater NA during the holiday. Results are discussed in light of perceived hope for rewarding safe emotional contact for those daters in contrast to the greater possibility for social threat associated with group celebration typical of St. Patrick's Day.  相似文献

Examined the relation of the depression aspect of the tripartite model of depression and anxiety to the diagnostic status and future symptoms of two samples that included 74 child and adolescent psychiatric inpatients, ages 7 to 17 years (M = 13.57, SD = 2.39), some with either internalizing or externalizing diagnoses. The tripartite model suggests that anhedonia (low positive affect, or PA) differentiates depression from other conditions, whereas generalized negative affect (NA) also characterizes depression but is not specific to it. In this study, differences among children in PA and NA were associated with depressive versus externalizing diagnostic status and with future symptoms of depression. Depressive disorder diagnoses were associated with the combination of low levels of PA and high levels of NA. Changes over time in depression, but not in anxiety, also were associated with the combination of low PA and high NA. Results provide support for the applicability, clinical utility, and extension of the tripartite model with children.  相似文献

Positive (PA) and Negative (NA) Affect scales were analyzed using the Pleasure-Arousal-Dominance (PAD) Emotion Model. PA was weighted by high arousal, pleasure, and dominance (listed in order of beta weights), thus approximating exuberance in PAD space. NA and markers of somatic anxiety were weighted by displeasure, high arousal, and submissiveness, approximating anxiety in PAD space. PA (or exuberance) represented only one of four basic variants of positive affect (exuberant, relaxed, dependent, docile) and NA (or anxiety) represented only one of four basic categories of negative affect (hostile, anxious, disdainful, bored). Thus, PA and NA lacked validity as general and balanced measures of positive and negative affect, respectively. Indeed, the counterintuitive mutual independence of PA and NA was possible only because PA (and NA) dealt narrowly with selective aspects of positive (negative) affect. The PAD alternative to the tripartite model showed anxiety and depression shared unpleasant and submissive temperament characteristics but differed because anxiety involved more arousability than depression.  相似文献

The applicability of the tripartite model of emotion, which distinguishes the shared aspect of depression and anxiety, negative affect (NA), from their respective specific components of low positive affect (PA) and physiological hyperarousal (PH), was examined in 472 elementary and high school students. The relations among depression, anxiety, and the three tripartite dimensions were examined for the total sample and across four subgroups based on age and gender. High school girls reported more depression, anxiety, NA, and PH than the other groups, and lower PA as assessed by the PANAS-C, but not the AFARS. Using structural equation modeling, the tripartite model proved to be a reasonably good fit for the total sample. Among the subgroups, the best fit was found for high school girls. However, several findings for the total sample and for individual subgroups were not consistent with the tripartite model, raising issues related to the independence and specificity of the tripartite constructs and their measurement. Alternative age- and gender-specific models to better account for the shared and unique aspects of depression and anxiety in children need to be explored.  相似文献

The authors assessed the reliability and validity of the Affect and Arousal Scale for Children (AFARS; Chorpita, Daleiden, Moffitt, Yim, & Umemoto, 2000). The AFARS is a new measure of children's positive affect (PA), negative affect (NA), and physiological hyperarousal (PH). In the first study, 176 school children, 7 to 17 years of age, were administered measures of childhood worry, anxiety sensitivity, and autonomic arousal and their parents completed a child behavior problem checklist. In a second study, two groups of 100 and 114 school children, 8 to 18 years of age, were administered measures of childhood depression and anxiety, respectively, Also, 120 of these children took part in a 1-week retest administration of the AFARS. These studies provided preliminary evidence of acceptable 1-week test–retest reliability, convergent validity, and discriminant validity for the AFARS PA, NA, and PH scales. However, the predicted pattern of convergent and discriminant relations with parent-reported criterion only emerged for children over 11 years of age. Further, a consistent positive relation emerged between NA and PH, yet each of these scales accounted for unique variance in the prediction of criterion measures.  相似文献

The ability to differentiate anxiety and depression has been a topic of discussion in the adult and youth literatures for several decades. The tripartite model of anxiety and depression proposed by L. A. Clark and D. Watson (1991) has helped focus the discussion. In the tripartite model, anxiety is characterized by elevated levels of physiological hyperarousal (PH), depression is characterized by low levels of positive affect (PA), and negative affect (NA) or generalized emotional distress is common to both. The advent of the model led to the development of measures of tripartite constructs and subsequent validity studies. The tripartite model and resultant activity concerning the model was largely devoted to adult samples. However, those interested in anxiety and depression among youth are now incorporating the tripartite model in their work. This paper examines the current influence of the tripartite model in the youth literature, especially with regard to measuring anxiety and depression.  相似文献

Using a combined sample (N = 1,215) of referred children and children from the general population aged between 8 and 14 years, the present study addressed two research goals: First, latent mean differences (depending on the individual’s sex or psychopathology level) in anxiety, depression, Positive Affect (PA), Negative Affect (NA) and Physiological Hyperarousal (PH) were examined. Secondly, the structure of anxiety and depression was investigated from a tripartite model perspective in boys and girls with high versus low levels of psychopathology respectively. When relating the latent mean level differences in NA, PA, and PH with those in anxiety and depression, the results suggest that higher levels (depending on the individual’s sex and psychopathology status) of anxiety or depression are associated with higher levels of PH and lower levels of PA, whereas no consistent pattern was found between mean level differences in NA on the one hand and mean level differences in anxiety/depression on the other. Results further demonstrated that a better fit was obtained for the dual than for the unitary construct representation in boys or girls with high or low levels of psychopathology, thereby suggesting that a valid distinction can be made between anxiety and depression in children between 8 and 14 years old, irrespective of their sex or level of psychopathology. However, when looking at the structural relations of the dual construct representation of anxiety and depression with NA, PA and PH in each of the four groups separately, it became evident that the PH and PA tripartite dimensions could not account for the unique aspects of anxiety and depression respectively. Moreover, PH rather than NA was found to be common for anxiety and depression.  相似文献

The current study was the 1st to examine the psychometric properties of the Positive and Negative Affect Schedule for Children-Parent Version (PANAS-C-P) using a large school-based sample of children and adolescents ages 8 to 18 (N = 606). Confirmatory factor analysis supported a 2-factor (correlated) model of positive affect (PA) and negative affect (NA). The PANAS-C-P scale scores also demonstrated acceptable internal consistency and convergent and divergent validity. The PANAS-C-P PA and NA scale scores also related to measures of anxiety and depression in a manner consistent with the tripartite model. Scale means and standard deviations were reported by grade and sex to provide normative data for the PANAS-C-P scales. Results from the present study provide initial support for the PANAS-C-P as a parent-reported perspective of youth PA and NA among school-based youths.  相似文献

We examined the roles of trait curiosity and social anxiety (and the contributions of the behavioral inhibition and activation systems; BIS, BAS) in predicting positive and negative affect (PA; NA) during social interactions. In Study 1, individuals interacted with same-sex confederates on topics that gradually escalated in emotional self-disclosure. In Study 2, cross-sex pairs of students were randomly assigned to a closeness-generating or small-talk interaction. There were several consistent findings across studies. Higher curiosity uniquely predicted greater interpersonally generated PA. Higher social anxiety uniquely predicted greater interpersonally generated NA in Study 1, and in Study 2, this relationship varied by social context. Specifically, high compared to low socially anxious individuals reported greater NA during small-talk, with no differences during intimate interactions. Furthermore, Study 2 demonstrated that individuals with stronger BAS’s experienced greater PA in the intimate compared to small-talk condition. There appear to be important traits that differentially contribute to appetitive and aversive interpersonal experiences.  相似文献

Traditional cognitive-behavioral therapy (CBT) for anxiety disorders has been designed to target reductions in negative affect (NA) associated with defense-related processes. However, a subset of anxiety disorders, including social anxiety disorder (SAD), are also characterized by low positive affect (PA) resulting from separate deficits in appetitive-related processes. In contrast to CBT, “third-wave” approaches, such as acceptance and commitment therapy (ACT), align more consistently with motivational processes and, as a result, PA. However, the differential effect of CBT and ACT on PA and NA has yet to be investigated. Using secondary data from a randomized controlled trial, the present study sought to compare CBT’s (n = 45) and ACT’s (n = 35) effect on PA and NA in SAD. Findings were compared to a wait-list (WL) control condition (n = 31), as well as normative data from a general adult sample. Baseline PA and NA were also examined as moderators and predictors of theory-relevant treatment outcomes. NA decreased significantly in both CBT and ACT from pre to posttreatment. Although ACT outperformed WL in reducing NA, this effect was not observed for CBT. PA increased significantly in both CBT and ACT from pre to posttreatment, with neither ACT nor CBT outperforming WL in increasing PA. Neither PA nor NA were found to moderate theoretically relevant treatment outcomes. Findings suggest that ACT and CBT share common treatment mechanisms, making them more similar than distinct. Further efforts should be focused on optimizing CBT’s and ACT’s influence on threat and reward learning, and elucidating common processes of change.  相似文献

The purpose of this research is to examine the association between attachment insecurities (anxiety and avoidance) and both subjective well‐being (positive affect [PA] and negative affect [NA] and life satisfaction) and relationship satisfaction. There were 174 Spanish heterosexual couples with a mean length of relationship of 13.9 years who participated in the study. The hypotheses were tested according to the actor–partner interdependence model. We proposed a model in which PA and NA could mediate the association between attachment insecurities and life and relationship satisfaction. Results show that (1) actor effects are more frequent than partner effects; (2) anxious attachment tends to be related to NA and avoidant attachment to PA; (3) avoidance is more detrimental than anxiety for relationship satisfaction at individual and dyadic levels, and (4) there are some mediational effects of NA and PA in the association between attachment insecurities and life and relationship satisfaction.  相似文献

The structure of affective well-being and the relationship between positive affect (PA) and negative affect (NA) have rarely been examined among adolescents. The aim of the present research was to investigate the question of bipolarity versus independence of PA and NA as measured by the PANAS across three studies in adolescent samples. The results of Study 1 (N = 1038) showed that a two-factor structure of the PANAS, with correlated PA and NA and allowed correlated errors between similarly worded items provided the best fit to data. Study 2 included three independent samples (total N = 1071), and showed that PA and NA differed in terms of their relationship to various well-being indicators. Study 3 (N = 482) tested the predictive validity of PA and NA in a 5 month follow-up design, and showed that both PA and NA had independent predictive benefits for depression, risky behaviors and life satisfaction, and that PA had no unique role in the prediction of stress and anxiety, while NA had no unique role in the prediction of academic achievement. The results of the present research provided strong support for the relative independence of PA and NA as measured by the PANAS among adolescents.  相似文献

OBJECTIVE: To characterize the influence of state and trait affect on HIV risk behaviors. DESIGN: Men who have sex with men (N = 155) completed reports of trait affect and daily reports of affect and sexual behaviors each night for up to 30 days. MAIN OUTCOME MEASURES: Analyses focused on the role of state and trait positive activation (PA), negative activation (NA), anxious arousal (AA), and sexual activation (SA) on sexual risk taking, operationalized as having a sex partner, a partner-related risk composite, and an HIV risk behavior composite. RESULTS: State SA was positively associated with having a sex partner and HIV risk behaviors; trait SA was positively associated with partner-related risk. State AA was negatively associated with having a sex partner and positively associated with HIV risk behaviors. Trait AA had a negative association with partner-related risk and moderated the effects of state AA. State PA was negatively associated with HIV risk behaviors, and trait PA had a main effect on having a sex partner. NA had no significant trait or state effects. CONCLUSION: These data suggest a role for multiple affective states in sexual risk taking. Models of HIV risk-taking behaviors should be extended to include affective processes.  相似文献

The current study examined the nature of retrospective recall of affect in depressed participants and nonclinical controls. Utilising the Experience Sampling Method, we compared average momentary affect reports to retrospective summaries of the same period of time. Both groups exhibited exaggerated retrospective summaries of positive affect (PA) and negative affect (NA). Greater bias for PA than NA was found in the controls but not the depressed. Across groups, depressed individuals exhibited more absolute inaccuracy in their recall of NA but not PA. For depressed and nonclinical individuals, retrospective summaries of PA were better predicted by an average of all weekly momentary PA than a combination of the most intense (“peak”) PA and most recent (“end”) PA experiences. For nonclinical participants, retrospective NA was better predicted by an average of all weekly momentary NA. For depressed individuals, however, no clear advantage to predicting retrospective NA by average weekly NA relative to a combination of peak NA and end NA was found. Based on our findings, clinicians should realise that depressive cognition may not lie in recall that is less positive and more negative than “reality” but in retrospective intensifications of all affect that are, compared to normal, relatively greater for negative than for positive affect.  相似文献

Neuroendocrine dysfunction is hypothesized to be an early emerging vulnerability marker for depression. We tested whether the main and interactive effects of maternal psychopathology and early child temperamental vulnerability for depression assessed at age three predicted offspring’s basal cortisol function at age 6 years. 228 (122 males) children participated in the baseline and follow-up assessments. At age three, maternal lifetime psychopathology was assessed with a diagnostic clinical interview, and child temperamental positive affectivity (PA) and negative affectivity (NA) were assessed using laboratory observations. At age six, children’s waking and evening cortisol were assessed on 2 days. Maternal lifetime anxiety predicted offspring’s higher morning cortisol at age six. Child temperamental NA at age three predicted higher evening cortisol at age six. There was a significant interaction between maternal lifetime depression and child temperamental PA at age three in predicting offspring’s morning cortisol at age six. For the offspring of mothers with lifetime depression, higher PA at age 3 predicted lower morning cortisol at age 6. These findings highlight the importance of examining the main and interactive effects of maternal psychopathology and early child temperamental vulnerability in predicting the development of offspring’s stress physiology. Findings hold significance in identifying etiological mechanisms of risk and delineating the complex developmental pathways to psychopathology.  相似文献

Bulimia nervosa (BN) is characterized by a pattern of binge eating and compensatory behaviors as well as an overemphasis on body weight and shape in self-evaluation. Although cognitive behavioral therapy (CBT) is efficacious, recent reviews suggest that only 30% of patients reach abstinence at posttreatment. One potential reason for these poor outcomes is that CBT fails to adequately reduce elevated negative affect (NA) and shape and weight concern, which have been shown to be correlated with poorer treatment outcomes in BN. Therefore, novel treatment components that focus on improving NA and shape and weight concern are needed in order to enhance outcomes. Promoting physical activity (PA) is a promising avenue through which to reduce NA and improve body image in healthy individuals, other clinical populations (e.g., individuals with depression or anxiety), and individuals with eating disorders. While prescribing PA for individuals with BN has been controversial (due to concerns that exercise maybe be used to compensate for binge episodes or become driven or compulsive), this approach may have many benefits, including promoting healthy lifetime exercise habits that reduce likelihood of relapse through the improvement of emotion regulation skills and weight regulation.Given the promise of PA for targeting key maintenance factors of BN, we developed a 12-session healthy PA promotion intervention for BN and tested initial feasibility, acceptability, and preliminary target engagement in an iterative case series design (n = 3). The treatment provided cognitive-behavioral skills designed to identify, practice, and achieve behavioral goals while asking patients to engage in up to 150 minutes of moderate-to-vigorous PA per week, which was preplanned during each session with the client’s therapist.Results suggested that the healthy PA promotion intervention was both feasible and acceptable to deliver. In addition, the intervention resulted in a clinically significant decrease in BN symptom frequency in each participant. Further, participants showed clinically significant decreases in NA and shape and weight concern.The current study demonstrates that healthy PA interventions can have beneficial effects on BN symptoms, NA, and shape and weight concern. However, due to the small sample size, conclusions must be treated with caution. Future research should investigate additional approaches for promoting healthy PA and include a larger sample in order to further test initial efficacy of this treatment approach.  相似文献

The Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988) is one of the most widely used affect scales. Nevertheless, the relation between its two scales, positive affect (PA) and negative affect (NA), is still controversial. Previous results that suggest independence between NA and PA were limited to manifest variables. In this study, the relation between PA and NA for both state and trait instructions was analyzed by means of structural equation modeling. Two hundred ninety-two participants responded to the PANAS at three occasions of measurement. No association was found between trait PA and NA, but significant negative correlations between state PA and NA emerged. In the second step, the observed variance of state PA and NA was decomposed into a dispositional component, an occasion-specific component, a method-specific component, and a component due to measurement error by employing a multi-construct latent state–trait model. This analysis confirmed and extended the results of our first analysis: the dispositional components of state PA and NA were unrelated. In contrast, the situation-specific components were negatively associated. Thus, the negative correlation between state PA and NA could be traced back to situation-specific effects.  相似文献

Depression disturbs mood, but a clear picture of diurnal mood rhythms in depression has yet to emerge. This study examined variations in positive affect (PA) and negative affect (NA), two dimensions of mood that generate diurnal patterns among healthy individuals. Repeated measurements of NA and PA in daily life were obtained over 6 days from 47 depressed outpatients and 39 healthy individuals using the Experience Sampling Method. Relative to healthy individuals, depressed individuals exhibited increasing PA levels during the day with a later acrophase. In contrast, depressed persons' NA exhibited a more pronounced diurnal rhythm and was more variable from moment to moment than healthy individuals'. Ambulatory mood measurements in depression suggest distinct diurnal disturbances of positive and negative affect.  相似文献

ABSTRACT

The differentiation of trait anxiety and depression in nonclinical and clinical populations is addressed. Following the tripartite model, it is assumed that anxiety and depression share a large portion of negative affectivity (NA), but differ with respect to bodily hyperarousal (specific to anxiety) and anhedonia (lack of positive affect; specific to depression). In contrast to the tripartite model, NA is subdivided into worry (characteristic for anxiety) and dysthymia (characteristic for depression), which leads to a four-variable model of anxiety and depression encompassing emotionality, worry, dysthymia, and anhedonia. Item-level confirmatory factor analyses and latent class cluster analysis based on a large nation-wide representative German sample (N?=?3150) substantiate the construct validity of the model. Further evidence concerning convergent and discriminant validity with respect to related constructs is obtained in two smaller nonclinical and clinical samples. Factors influencing the association between components of anxiety and depression are discussed.  相似文献
