Specificity of cost and probability biases in social anxiety: Comparing status and belongingness threats.

BACKGROUND: Social anxiety (SA) is characterized by concerns about the expected occurrence (probability) and anticipated distress (cost) of social threats. Unclear is whether SA correlates specifically with biased expectations of belongingness or status threats. AIMS: We aimed to discern if SA is uniquely tied to biased expectancies of either belongingness or status threats. MATERIALS AND METHODS: We assessed 757 participants' perceptions of exclusion and put-down scenarios, analysing associations between SA and threat perceptions. DISCUSSION: Our findings support the status-sensitivity hypothesis, suggesting individuals with high SA are particularly attuned to the perceived cost of status threats, potentially informing treatment approaches. CONCLUSION: Understanding SA's link to status concerns enhances therapeutic strategies, emphasizing the need to address status-related situations, cognitions, and emotions in interventions.

Probability, cost, and interpretation biases' relationships with depressive and anxious symptom severity: differential mediation by worry and repetitive negative thinking.

People high in depressive or anxious symptom severity show repetitive negative thinking, including worry and rumination. They also show various cognitive phenomena, including probability, cost, and interpretation biases. Since there is conceptual overlap between these cognitive biases and repetitive negative thinking - all involve thinking about potential threats and misfortunes - we wondered whether repetitive negative thinking could account for (mediate) these cognitive biases' associations with depressive and anxious symptom severity. In three studies, conducted in two languages and cultures, cost bias and (in two studies) interpretation bias only predicted symptom severity via worry and repetitive negative thinking; this suggests these biases are actually associated with repetitive negative thinking, rather than with symptoms. In contrast, probability bias showed direct relationships with depressive (all studies) and anxious (two studies) symptom severity, suggesting its relationships with symptoms are partly independent of repetitive negative thinking. These results show the value of studying relationships among the various cognitive features of psychopathology. Furthermore, new interventions which target cognitive biases in depression or anxiety must show that they can improve upon cognitive behavioural therapy, which is already widely available, targets both repetitive negative thinking and probability bias, and is highly effective.

Attentional control and estimation of the probability of positive and negative events.

People high in negative affect tend to think negative events are more likely than positive events ("probability bias"). Studies have found that weak attentional control exaggerates another negative affect-related cognitive bias - attentional bias - but it is not clear why this might be. We therefore wanted to know whether weak attentional control would be related to probability bias too. Four studies, with predominantly female student samples (N = 857), revealed correlations of around -.38 between attentional control and probability bias. This remained significant when trait anxiety and depression were controlled; there were no interactions between attentional control and negative affect. Studies 3 and 4 found that attentional control's relationship with probability bias was partly mediated by emotion regulation ability. These results suggest attentional control is important for regulating affect-related cognitive biases, and for emotion regulation in general. Furthermore, because cognitive biases are thought to be important for maintaining emotional disorders, these results are also consistent with weak attentional control being a risk factor for these disorders.

A novel computer task to assess outcome probability bias.

This research describes the development of a novel computer task to assess outcome probability bias for social anxiety - the tendency to make unrealistically high evaluations of the probability of experiencing a negative outcome when anticipating a social encounter - that improves upon existing measures by using images and by assessing the construct at automatic and controlled levels of processing. The first study evaluated the images selected for the task and the extent to which the task elicited automatic responding, and the second study evaluated the task's reliability and validity. Across both studies, 203 college students completed the outcome probability bias computer task, standardized self-report questionnaires of outcome probability bias, outcome cost bias, depression and stress, and safety behaviors, and completed a behavioral avoidance task. The task demonstrated good to excellent internal consistency (α = 0.82 - 0.96) and significant positive correlations with a standardized measure of outcome probability bias (r = 0.33 - 0.48). With one exception, all hypotheses regarding the convergent, discriminant, construct, and criterion validity of the task were supported. Pending replication and additional evaluation, the outcome probability bias computer task may advance research on social anxiety disorder and may be adapted for use with other related disorders.

Biased probability estimates in trait anxiety and trait depression are unrelated to biased availability.

BACKGROUND AND OBJECTIVES: People high in trait anxiety or depression overestimate the probability of negative events, and underestimate the probability of positive events, relative to people low in trait anxiety and depression. Although this probability bias may be fundamental to some emotional disorders, its causes are not well understood. The dominant explanations are based on the availability heuristic: people relatively high in anxiety or depression find it relatively easy to imagine reasons why bad things might happen to them, and this affects their probability estimates. We tested, for the first time, whether individual differences in the availability of such reasons mediate the relationships between trait anxiety or depression and probability bias, in a nonclinical sample. METHODS: Two hundred and seventy-eight undergraduates generated reasons why a set of positive and negative events might vs. might not happen to them, before rating those events' probability and potential impact on their lives. RESULTS: Individual differences in the availability of reasons why good and bad events might vs. might not happen did not mediate the sizeable relationships between trait anxiety and probability bias, and between trait depression and probability bias; these relationships remained significant when availability was controlled. Results for the impact of events ('cost bias') were less clear. LIMITATIONS: Replication with patient groups would be invaluable; different operationalisations of availability may change the results. CONCLUSIONS: Availability can influence probability estimates, but it does not explain why we see probability bias in people with high trait anxiety or depression.

Social Cost Bias, Probability Bias, and Self-Efficacy as Correlates of Behavioral Action in Social Anxiety.

The present study investigated the role of social cost bias, probability bias, and self-efficacy as correlates of behavioral action in a nonclinical sample of 197 individuals, using a series of vignettes and self-report measures. The findings indicated that, as hypothesized, social cost bias, probability bias, and self-efficacy were associated with social anxiety. While social anxiety was associated with behavioral action, the three cognitive factors were associated with behavioral action above and beyond the contribution of social anxiety. However, contrary to the hypothesis, self-efficacy was the only cognitive factor directly associated with behavioral action when all variables were in the model. This information has implications for potential methods and target mechanisms for increasing client engagement with exposures and behavioral experiments in treatments for social anxiety.

A Comparison of Cognitive and Behavioral Approaches for Reducing Cost Bias in Social Anxiety.

Cognitive-behavioral theories suggest that anxiety is maintained in part by estimates of the probability and cost of feared negative outcomes. Social phobia may be unique among the anxiety disorders in that it is characterized by overestimates of the cost of events that are objectively noncatastrophic (e.g., committing social mishaps). As such, treatment approaches that target cost bias may be particularly effective in reducing social phobia symptoms. This study examined the efficacy of 2 cost-specific techniques in a single-session intervention for social anxiety. Individuals (n = 61) with elevated social interaction anxiety were randomly assigned to an expressive writing control condition, a cognitive restructuring condition, or a behavioral experiment condition. Results demonstrated that the cognitive restructuring condition produced significantly greater improvement in indices of social anxiety than the other conditions. Reduction in cost bias fully mediated the significantly greater improvement in social interaction anxiety in the cognitive restructuring condition relative to the behavioral experiment condition. The present findings highlight the value of techniques designed to reduce cost biases in social anxiety. Clinical implications are discussed.
