Are 60-minute prolonged exposure sessions with 20-minute imaginal exposure to traumatic memories sufficient to successfully treat PTSD? A randomized noninferiority clinical trial.

The study aims to determine whether 60-minute sessions of prolonged exposure (PE) that include 20 minutes of imaginal exposure (IE) are noninferior to the standard 90-minute sessions that include 40 minutes of IE in treating posttraumatic stress disorder (PTSD) and to explore the relationship of treatment outcome to within- and between-session habituation and change in negative cognitions. Thirty-nine adult veterans with chronic PTSD were randomly assigned to 90-minute (n=19) or 60-minute (n=20) sessions of PE. PTSD symptoms were assessed by an unaware independent evaluator before and after treatment and at 6-month follow-up. Self-reports of depression and negative cognitions were assessed before and after treatment. Participants in both conditions showed significant reductions in PTSD symptoms. Sixty-minute sessions were found to be noninferior to 90-minute sessions in reducing PTSD symptoms, as the upper bound of the 95% confidence interval for the difference between conditions in the PTSD Symptom Scale-Interview (posttreatment: 6.00; follow-up: 6.77) was below the predefined noninferiority margin (7.00). Participants receiving shorter sessions showed less within- and between-session habituation than those receiving longer sessions, but no group differences in reductions in negative cognitions were found. The current findings indicate that the outcomes of 60-minute sessions of PE do not differ from those of 90-minute sessions. In addition, change in trauma-related cognitions and between-session habituation are both potential mechanisms of PE.

How does the therapeutic alliance develop throughout cognitive behavioral therapy for panic disorder? Sawtooth patterns, sudden gains, and stabilization

Abstract Objective: There has been little research on the development of the therapeutic alliance in cognitive behavioral therapy (CBT). This study aims to examine the development of therapeutic alliance in CBT for panic disorder. Method: Nineteen patients were treated with CBT for panic disorder. Pre- and post-session data of the therapeutic alliance and panic symptoms and cognitions were collected. Results: Several patterns were observed, including a sawtooth pattern (within-session improvements followed by decline between sessions; 63% of the patients), sudden gains in the alliance (58%), and late stabilization (89%). The sawtooth pattern was related to less symptom reduction between sessions (explained variance = 20–48%). Though not statistically significant, there were moderate effect sizes for the relationships between outcomes and early alliance and sudden gains (explained variance = 13–17%). Conclusions: Overall, results suggest that intensive data collection is likely to yield understanding of the relationship between therapy processes and outcomes.

Does cognitive reappraisal reduce anxiety? A daily diary study of a micro-intervention with individuals with high social anxiety.

OBJECTIVE To examine emotion regulation (ER) among individuals with high (HSA) and low social anxiety (LSA) and the effects of 1 week of practiced cognitive reappraisal using self-report, daily diary measures and lab tasks. METHOD HSAs received reappraisal (HSA-R; n = 43) or monitoring (HSA-M; n = 40) instructions. LSAs received monitoring instructions (LSA-M; n = 41). Self-report measures of social anxiety and ER, and a lab task of reappraisal were administered at baseline and after 1 week. Daily diaries of anxiety and ER were also collected. RESULTS At baseline, HSAs compared with LSAs reported lower self-efficacy of reappraisal and higher frequency and self-efficacy of suppression, but no differences emerged in the reappraisal task. Following the intervention, the HSA-R compared with the HSA-M reported lower symptom severity, greater self-efficacy of reappraisal but equal daily anxiety. HSA-R used reappraisal mostly combined with suppression (74.76% of situations). Post hoc analyses demonstrated that clinical diagnosis, but not severity, moderated the intervention effect. CONCLUSIONS The results demonstrate the efficacy of a short intervention in social anxiety, and provide additional areas of research for improving its treatment.

Are individuals diagnosed with social anxiety disorder successful in regulating their emotions? A mixed-method investigation using self-report, subjective, and event-related potentials measures

BACKGROUND Models of social anxiety emphasize the role of emotion dysregulation, but the nature of these impairments needs clarification. METHODS We utilized a mixed-method approach to examine impairments in cognitive reappraisal and expressive suppression in social anxiety disorder. Forty nine treatment-seeking individuals diagnosed with social anxiety disorder and 35 healthy controls completed self-reports and a lab-based task of suppression and reappraisal. Unpleasantness ratings and event-related potentials (ERPs) were collected while participants regulated their emotions in response to shame-arousing pictures. ERP analyses focused on the late positive potential, a measure of increased attention to emotional stimuli that is reduced during emotion regulation. RESULTS Participants with social anxiety reported less frequent and effective use of reappraisal and more frequent and effective use of suppression than controls. Counter to most models and our hypotheses, participants with social anxiety were more successful than controls in lab-based reappraisal as measured by unpleasantness ratings, but no differences emerged for ERPs. No differences were found in measures of lab-based suppression. LIMITATIONS Use of standardized, and not participant-generated, materials in the lab-based task of emotion regulation may limit the generalizability of the findings. CONCLUSIONS Subjective appraisals of self-efficacy and frequency suggest strong impairments in emotion-regulation in social anxiety that are not revealed in the laboratory. Models and treatment protocols should specify the exact nature of emotion dyregulation in social anxiety, highlighting difficulties in implementation of potentially intact emotion regulation abilities.

Emotional Reactions to Facial Expressions in Social Anxiety: A Meta-Analysis of Self-Reports

The current meta-analysis reviews 24 studies on self-reported emotional reactions to facial expressions (social rejection, social acceptance, and neutral) in socially anxious versus nonanxious individuals. We hypothesized that socially anxious individuals would perceive all face types as less approachable, more negative, and more arousing. After correcting for biases, results showed that socially anxious individuals, compared to controls, reported lower approachability to all types of expressions and higher arousal in response to neutral expressions. Variances among effects usually could not be explained by the proposed moderators. This suggests that current conceptualizations of social anxiety should take into account the willingness to approach social stimuli rather than global measures of emotion or arousal.

A pilot randomized clinical trial of cognitive behavioral therapy versus attentional bias modification for social anxiety disorder: An examination of outcomes and theory-based mechanisms

No studies have compared face-to-face cognitive-behavioral therapy (CBT) and attention bias modification (ABM) for social anxiety disorder (SAD) and their purported mechanisms. We asked: 1) Is CBT more effective than ABM? and 2) Are changes in attentional biases and cognitions temporally related to symptom change? Forty-three patients were randomly assigned to 8 sessions of ABM or up to 20 sessions of individual CBT. Intent-to-treat results revealed that CBT was superior to ABM in response rates and on symptom measures at endpoint, but not on other measures. No differences were found on measures in rates of change between CBT and ABM. Frequency of negative cognitions changed in both groups and negative beliefs changed only in CBT. Attentional bias did not change in either group. Cognitive changes bidirectionally correlated with symptom change in cross-lagged analyses in CBT, but not in ABM, suggesting a reciprocal relationship. Trial-level bias away from negative faces was simultaneously related to symptom change in ABM only. Results suggest that CBT is superior to ABM when administered at their typical doses, but raise questions given the similar rates of change. In addition, results support theories of cognitive change and raise questions about changes in attentional biases in CBT.

Emotion regulation in social anxiety: a systematic investigation and meta-analysis using self-report, subjective, and event-related potentials measures

ABSTRACT Recent models of social anxiety disorder emphasise the role of emotion dysregulation; however, the nature of the proposed impairment needs clarification. In a replication and extension framework, four studies (N = 193) examined whether individuals with social anxiety (HSAs) are impaired in using cognitive reappraisal and expressive suppression. Self-reports and lab-based tasks of suppression and reappraisal were utilised among individuals with high and low levels of social anxiety. A meta-analysis of these studies indicated that, compared to controls, HSAs reported less frequent and effective use of reappraisal and more frequent and effective use of suppression. Counter to most models and our hypotheses, HSAs were more successful than controls in lab-based reappraisal of shame-arousing pictures as measured by subjective ratings, but not by event-related potentials. HSAs were less successful than controls in lab-based suppression of shame-arousing pictures as measured by subjective ratings, but not by event-related potentials. The results held even when participants were under social stress (impromptu speech anticipation). Overall, subjective reports of HSAs reveal strong deficits in emotion regulation whereas lab-based measures provided less conclusive evidence of such deficits. These results suggest that individuals with social anxiety experience difficulties implementing their reappraisal abilities in daily life.

Emotion Regulation Strategies in Cognitive Behavioral Therapy for Panic Disorder

Emotion regulation (ER) has been incorporated into many models of psychopathology, but it has not been examined directly in cognitive behavioral therapy (CBT) for panic disorder with agoraphobia (PD/A). In this study, a preliminary model of ER in CBT for PD/A is proposed based on existing theories, and several propositions of the model are tested. We hypothesized that increases in cognitive reappraisal would precede decreases in biased cognitions, decreases in expressive suppression would follow decreases in biased cognitions, and a reduction in symptom severity would follow decreases in expressive suppression. Twenty-nine patients who received CBT for PD/A completed weekly self-report measures of symptom severity, anxiety sensitivity, reappraisal and expressive suppression. In addition, patients were compared to a matched normal sample. Cross-lagged analyses partially supported the hypotheses. Reappraisal did not change until late stages of therapy and was generally not associated with treatment outcome. Suppression decreased significantly and exhibited a reciprocal relationship with biased cognitions. Symptom reduction followed decreases in suppression as hypothesized. However, patients did not differ in ER from matched controls at either pre- or posttreatment. Results suggest the important distinction between reappraisal and appraisal, and stress the role of session-by-session decreases in suppression as a predictor of symptom reduction.
