Does the judicious use of safety behaviors improve the efficacy and acceptability of exposure therapy for claustrophobic fear

Exposure therapy is traditionally conducted with an emphasis on the elimination of safety behaviors. However, theorists have recently suggested that the judicious use of safety behaviors may improve the tolerability of this treatment without reducing its efficacy. The present study tested this notion by randomly assigning participants with high claustrophobic fear to receive a single-session intervention with or without access to safety aids during early exposure trials. Improvement was generally equivalent between the treatment conditions, and no reliable benefits or drawbacks were associated with the judicious use of safety behaviors. The theoretical and clinical implications of these findings are discussed.

Theory-based training strategies for modifying practitioner concerns about exposure therapy

Despite the well-established efficacy of exposure therapy in the treatment of pathological anxiety, many therapists believe this treatment carries an unacceptably high risk for harm, is intolerable for patients, and poses a number of ethical quandaries. These beliefs have been shown to account for two related problems: (a) underutilization of exposure therapy, and (b) overly cautious and suboptimal delivery the treatment, which likely attenuates treatment outcomes. At present, there is little guidance for those who train exposure therapists to address these concerns. This article reviews therapist negative beliefs about exposure therapy and discusses their modification based on findings from social and cognitive psychology pertinent to belief change, including dual-processing in reasoning, the need for cognition and affect, and attitude inoculation. A number of strategies are offered for augmenting training in exposure therapy in order to promote positive beliefs about the treatment. These strategies involve: (a) therapists engaging in simulated exposure therapy exercises and presenting arguments in defense of exposures safety, tolerability, and ethicality, and (b) training therapists using emotion-based appeals (e.g., case examples) to supplement research findings. Directions for future research on practitioner concerns about exposure therapy are discussed.

Cognitive defusion versus cognitive restructuring in the treatment of negative self-referential thoughts: An investigation of process and outcome

Within traditional cognitive therapy, cognitive restructuring is often used to challenge the veracity of dysfunctional thoughts. In contrast, acceptance and commitment therapy (ACT) uses “cognitive defusion” techniques to change the function of negative thoughts rather than modify their content. Previous research has shown that a cognitive defusion technique known as the “milk exercise” (rapidly repeating a self-referential, one-word thought such as “fat”) reduces the discomfort and believability associated with negative thoughts. This study sought to replicate and extend these findings by comparing the impact of cognitive defusion with that of cognitive restructuring in a sample of participants distressed by negative thoughts about their body shape. Participants received a detailed rationale and training followed by instructions to practice the assigned technique as homework for 1 week. Results indicated that both cognitive techniques produced substantial improvements that generalized well beyond the specific thoughts targeted for treatment. Clear differences in treatment process and the course of improvement were evident. Findings are discussed in the context of theoretical and practical similarities and differences between these two approaches.

Do Cognitive Reappraisal and Diaphragmatic Breathing Augment Interoceptive Exposure for Anxiety Sensitivity

Interoceptive exposure (IE) is an effective procedure for reducing anxiety sensitivity (AS) and the symptoms of panic disorder. However, considerable variance exists in how IE is delivered among clinicians, and the extent to which IE is enhanced by the concurrent use of cognitive reappraisal (CR) and diaphragmatic breathing (DB) is unclear. Participants (N = 58) with high AS were randomly assigned to one of four single-session interventions: (a) IE only, (b) IE 1 CR, (c) IE 1 CR 1 DB, or (d) expressive writing control. IE was superior to expressive writing in reducing AS and associated anxiety symptoms. The addition of CR and DB did not enhance the benefits of IE at either posttreatment or 1-week follow-up. These findings highlight the specific efficacy of IE in reducing AS and call into question the common practice of combining IE with cognitive and breathing strategies. Theoretical and clinical implications are discussed.

Probability and Cost Biases in Social Phobia: Nature, Specificity, and Relationship to Treatment Outcome

Social phobia is maintained in part by cognitive biases concerning the probability and cost of negative social events. More specifically, individuals with social phobia tend to believe that negative social events are extremely likely to occur, and that if such events were to happen, the consequences would be awful or unbearable. The aim of the present review is to critically evaluate research on the nature and specificity of probability and cost biases in social phobia. Changes in probability and cost estimates during treatment and their relationship to treatment outcome are detailed. The review concludes with a discussion of how current cognitive behavioral interventions target these biases. Directions for future research are proposed.

Targeting the probability versus cost of feared outcomes in public speaking anxiety.

Cognitive-behavioral theory suggests that social phobia is maintained, in part, by overestimates of the probability and cost of negative social events. Indeed, empirically supported cognitive-behavioral treatments directly target these cognitive biases through the use of in vivo exposure or behavioral experiments. While cognitive-behavioral theories and treatment protocols emphasize the importance of targeting probability and cost biases in the reduction of social anxiety, few studies have examined specific techniques for reducing probability and cost bias, and thus the relative efficacy of exposure to the probability versus cost of negative social events is unknown. In the present study, 37 undergraduates with high public speaking anxiety were randomly assigned to a single-session intervention designed to reduce either the perceived probability or the perceived cost of negative outcomes associated with public speaking. Compared to participants in the probability treatment condition, those in the cost treatment condition demonstrated significantly greater improvement on measures of public speaking anxiety and cost estimates for negative social events. The superior efficacy of the cost treatment condition was mediated by greater treatment-related changes in social cost estimates. The clinical implications of these findings are discussed.

Development and Validation of the Shy Bladder Scale

Paruresis, characterized by the difficulty or inability to urinate in a variety of social contexts, is a scientifically under-studied phenomenon. One reason for this state of affairs is the paucity of reliable and valid measures for assessing this problem. The present article attempted to address this limitation by investigating the psychometric properties and validity of a new measure of paruresis: the Shy Bladder Scale (SBS). In two undergraduate samples, the SBS demonstrated excellent internal consistency and a stable factor structure assessing difficulty urinating in public, impairment and distress, and paruresis-related fear of negative evaluation. Undergraduate students evidenced very low levels of paruresis-related concerns. In contrast, SBS scores were markedly elevated among individuals recruited from an online support network who appeared to meet diagnostic criteria for paruresis-specific social phobia. Our findings highlight the SBSs potential utility as a measure of paruresis in clinical and research contexts.

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.

Breathing Retraining for Individuals Who Fear Respiratory Sensations: Examination of Safety Behavior and Coping Aid Hypotheses

Cognitive behavioral theorists have suggested that breathing retraining may be used as a safety behavior. Safety behaviors are acts aimed at preventing or minimizing feared catastrophe and may maintain pathologic anxiety by hindering resolution of maladaptive cognitive processes. An opposing position is that breathing retraining is an effective coping aid. This study examined the safety behavior and coping aid hypotheses as they apply to breathing retraining. Individuals high in fear of respiratory sensations were randomly assigned to a psychoeducation control condition (EDU; n = 27) or a psychoeducation plus breathing retraining condition (EDU+BR; n = 30). As compared to psychoeducation alone, the addition of breathing retraining neither limited improvement of cognitive processes (e.g., anxiety sensitivity) nor added to the gains observed on measures of coping (e.g., perceived control). The findings are evaluated in light of the available literature regarding breathing retraining and the safety behavior and coping aid hypotheses.
