Comparing the predictive capacity of observed in-session resistance to self-reported motivation in cognitive behavioral therapy

Self-report measures of motivation for changing anxiety have been weakly and inconsistently related to outcome in cognitive behavioral therapy (CBT). While clients may not be able to accurately report their motivation, ambivalence about change may nonetheless be expressed in actual therapy sessions as opposition to the direction set by the therapist (i.e., resistance). In the context of CBT for generalized anxiety disorder, the present study compared the ability of observed in-session resistance in CBT session 1 and two self-report measures of motivation for changing anxiety (the Change Questionnaire & the Client Motivational for Therapy Scale) to (1) predict client and therapist rated homework compliance (2) predict post-CBT and one-year post-treatment worry reduction, and (3) differentiate those who received motivational interviewing prior to CBT from those who received no pre-treatment. Observed in-session resistance performed very well on each index, compared to the performance of self-reported motivation which was inconsistent and weaker relative to observed resistance. These findings strongly support both clinician sensitivity to moments of client resistance in actual therapy sessions as early as session 1, and the inclusion of observational process measures in CBT research.     

Resistance and outcome expectations in cognitive‐behavioural therapy for generalised anxiety disorder

Greater client resistance has been consistently found to be negatively associated with outcome in psychotherapy. However, the pathways through which resistance impacts such outcomes are underexplored. Given that client outcome expectation (OE) has been identified as an important common factor in psychotherapy, the goals of the present study were to examine: (a) the impact of resistance on subsequent client and therapist OE (COE & TOE, respectively); and (b) whether COE and/or TOE mediate the relationship between resistance and outcome. These relationships were tested among 44 clients with severe generalised anxiety disorder treated with cognitive‐behavioural therapy in the context of a randomised controlled trial (Westra, Constantino, & Antony, 2016). Resistance was measured at a mid‐treatment session, and COE and TOE were assessed at baseline and immediately after the resistance session. Treatment outcome was measured via client‐rated worry severity at post‐treatment. As predicted, higher resistance was associated with lower subsequent COE and TOE; B = ?.73, p < .001 and B = ?.46, p < .001, respectively. In turn, lower post‐resistance COE predicted higher post‐treatment worry (B = ?.5, p < .001), indicating mediation. In contrast, TOE did not mediate the relationship between resistance and outcome (B = ?.02, p = .876). These results suggest that resistance can be demoralising to both clients and therapists. However, only lower client morale may be detrimental to therapy outcome. This study contributes to understanding outcome pathways through two common therapy processes.     

Mediators in psychological treatment of social anxiety disorder: Individual cognitive therapy compared to cognitive behavioral group therapy

According to cognitive-behavioral models of social anxiety disorder (SAD), four of the important maintaining mechanisms are avoidance, self-focused attention, anticipatory processing and post-event cognitive processing. Individual cognitive therapy (ICT) and cognitive behavioral group therapy (CBGT) both have substantial empirical support. However, it is unclear whether they achieve their effects by similar or different mechanisms. The aim of this study was to investigate whether changes in the four maintenance processes mediate clinical improvement in ICT and CBGT for SAD. We analyzed data from participants (N = 94) who received either ICT or CBGT in two separate RCTs. The results showed that ICT had larger effects than CBGT on social anxiety and each of the four potential mediators. More pertinently, moderated mediation analyses revealed significant between-treatment differences. Whereas improvement in ICT was mainly mediated by reductions in avoidance and self-focused attention, improvement in CBGT was mediated by changes in self-focused attention and in anticipatory and post-event processing. These results support the importance of the putative mediators, but suggest that their relative weights are moderated by treatment type.     

Implementation trial of a cognitive behavioural therapy programme for reducing student stress in the final year of secondary school

The final year of secondary school has been shown to be associated with heightened student stress. Psychological interventions have been shown to be effective in reducing and preventing distress in students during this school period, although the widespread adoption of these interventions into school settings is limited. There have been recent calls for research to examine the implementation success of evidence-based programmes when used by schools in school settings. The present study aimed to evaluate the implementation success of an evidence-based cognitive-behavioural therapy programme (Study without Stress) using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. At one Australian high school, all tutor group teachers were trained by the school counsellor to deliver the programme in standard school classes to students in the lead up to their final year of secondary school. Students (n = 80) and teachers (n = 11) reported on programme success against the RE-AIM framework at pre-intervention, post-intervention, and three-month follow-up. The findings indicated that SWOS was implemented successfully by the school. SWOS was associated with maintaining student stress levels at normal levels over time, as well as reducing the severity of stress for initially highly distressed students. The findings provide evidence from implementation science that SWOS can be adapted and delivered effectively by school staff to manage stress in final year secondary school students.     

A comparison of cognitive-behavior therapy with interpersonal and cognitive behavior therapy in the treatment of generalized anxiety disorder

Objective: The aim of this study was to compare the effectiveness of cognitive behavior therapy with the combination of cognitive behavior therapy and interpersonal therapy on decreasing the excessiveness of pathological worry and increasing happiness of the individuals with generalized anxiety disorder.

Method: The sample consisted of 36 female undergraduate students who referred themselves to the Isfahan University Counseling Center and met the criteria for GAD. They were randomly assigned into three groups; namely, two experimental groups and one control group. Before receiving the interventions all of the groups completed Penn State Worry Questionnaire and Oxford Happiness Inventory. One of the experimental groups underwent cognitive behavior therapy and the other one received the integration of cognitive behavior therapy and interpersonal therapy. The control group received no intervention.

Result: The statistical analyses indicated that the differences between the CBT and CBT+ IPT groups on excessive worry and happiness in the post tests were not significant. But significant mean differences were observed in the follow-ups regarding pathological worry and happiness between two groups.

Conclusion: It can be concluded that the integration of cognitive behavior therapy and interpersonal therapy can be applied as an effective intervention for decreasing the rate of GADs’ relapses after cognitive behavior therapy.     

A brief cognitive behavioural therapy psychoeducational group for Chinese people with chronic illnesses: an evaluation study

This pilot study attempted to examine the effectiveness of a brief cognitive behavioural therapy (CBT) psychoeducational group for Chinese people with chronic illness in Hong Kong. It adopted a single group design, and 52 participants joined the group. A questionnaire with three outcome measures, measuring general mental health, quality of life and dysfunctional attitudes and beliefs, was administered to participants at pre-test, post-test and six month follow-up. Repeated measures ANOVAs were employed and revealed positive changes in most of the outcome measures across the three time points. Cohen’s d showed a moderate to large effect size for most outcome measures. From a step care perspective, a culturally attuned brief CBT psychoeducational group may serve as an early intervention and a triage to attract suitable people with chronic illness to engage in the treatment process.     

The impact of religious cognitive behavioural therapy (RCBT) on general health among Iranians

The aim of this study was to determine the efficacy of religious cognitive behavioural therapy (RCBT) on general health among Iranians. This study was a randomised, single-blinded clinical trial from April 2017 to October 2017. One hundred forty-four Yazd citizens were selected using a cluster sampling method and randomly assigned to experimental or control groups. The experimental groups received 10 sessions of RCBT, lasting 45 minutes once a week and the control group remained on the waiting list. The results showed that mean general health scores in the experimental groups were significantly lower than those in the control group on the post-test. RCBT had the most positive impact on somatic symptoms, anxiety/insomnia, social dysfunction, depression, and mental health. Based on these findings RCBT can be considered a significant and effective practical therapy for improving both general and psychological health.     

The implementation of guided Internet-based cognitive behaviour therapy for panic disorder in a routine-care setting: effectiveness and implementation efforts

Panic disorder is a common mental disorder. Guided Internet-based cognitive behavioural therapy (Guided Internet-based cognitive behaviour therapy (ICBT)) is a promising approach to reach more people in need of help. In the present effectiveness study, we investigated the outcome of guided ICBT for panic disorder after implementation in routine care. A total of 124 patients were included in the study, of which 114 started the treatment. Large within-group effect sizes were observed on the primary panic disorder symptoms (post-treatment: d = 1.24; 6-month follow-up: d = 1.39) and moderate and large effects on secondary panic disorder symptoms and depressive symptoms at post-treatment and follow-up (d = .55–1.13). More than half (56.1%) of the patients who started treatment recovered or improved at post-treatment. Among treatment takers (completed at least five of the nine modules), 69.9% recovered or improved. The effectiveness reported in the present trial is in line with previous effectiveness and efficacy trials of guided ICBT for panic disorder. This provides additional support for guided ICBT as a treatment alternative in routine care.     

Applied relaxation vs. cognitive therapy in the treatment of generalized anxiety disorder

The present study investigated the efficacy of a coping-technique, applied relaxation (AR) and cognitive therapy (CT), in the treatment of generalized anxiety disorder. Thirty-six outpatients fulfilling the DSM-III-R criteria for generalized anxiety were assessed with independent assessor ratings and self-report scales before and after treatment and at a 1 yr follow-up. The patients were randomized and treated individually for 12 weekly sessions. The results showed that both treatments yielded large improvements, which were maintained, or furthered at follow-up. There was no difference between AR and CT on any measure. The drop-out rate was 12% for AR and 5% for CT. The proportions of clinically significantly improved patients were 53 and 62% at post-treatment and 67 and 56% at follow-up for AR and CT, respectively. Besides affecting generalized anxiety the treatments also yielded marked and lasting changes on ratings of worry, cognitive and somatic anxiety and depression. The conclusion that can be drawn is that both AR and CT have potential as treatments for generalized anxiety disorder but they have to be developed further in order to increase the efficacy to the level usually seen in panic disorder, 80-85% clinically improved.     

Randomised controlled trial of group cognitive behavioural therapy for comorbid anxiety and depression in older adults

Anxiety and depression are commonly comorbid in older adults and are associated with worse physical and mental health outcomes and poorer response to psychological and pharmacological treatments. However, little research has examined the effectiveness of psychological programs to treat comorbid anxiety and depression in older adults. Sixty-two community dwelling adults aged over 60 years with comorbid anxiety and depression were randomly allocated to group cognitive behavioural therapy or a waitlist condition and were assessed immediately following and three months after treatment. After controlling for cognitive ability at pre-treatment, cognitive behaviour therapy resulted in significantly greater reductions, than waitlist, on symptoms of anxiety and depression based on a semi-structured diagnostic interview rated by clinicians unaware of treatment condition. Significant time by treatment interactions were also found for self-report measures of anxiety and depression and these gains were maintained at the three month follow up period. In contrast no significant differences were found between groups on measures of worry and well-being. In conclusion, group cognitive behavioural therapy is efficacious in reducing comorbid anxiety and depression in geriatric populations and gains maintain for at least three months.     

A pilot randomized trial of metacognitive therapy vs applied relaxation in the treatment of adults with generalized anxiety disorder

Metacognitive Therapy (MCT) and Applied Relaxation (AR) were compared in a pilot treatment trial of generalized anxiety disorder (GAD). Twenty outpatients meeting criteria for DSM-IV-TR GAD were assessed before treatment, after treatment and at 6 m and 12 m follow-up. The patients were randomized and treated individually for 8-12 weekly sessions. There was no drop-out from MCT and 10% at 6 m follow-up from AR. At post-treatment and at both follow-up points MCT was superior to AR. Standardized recovery rates for MCT at post-treatment were 80% on measures of worry and trait-anxiety compared with 10% following AR. At 6 m follow-up recovery rates for MCT were 70% on both measures compared with 10% and 20% for AR. At 12 m follow-up recovery rates for MCT were 80% (worry) and 60% (trait-anxiety) compared with 10% and 20% following AR. The recovery rates for MCT are similar to those obtained in an earlier uncontrolled trial (Wells & King, 2006). The effect sizes and standardized recovery rates for MCT suggest that it is a highly effective treatment.     

Randomized trial of a meditation-based stress reduction program and cognitive behavior therapy in generalized social anxiety disorder

Mindfulness-based stress reduction (MBSR) has been reported to reduce anxiety in a broad range of clinical populations. However, its efficacy in alleviating core symptoms of specific anxiety disorders is not well established. We conducted a randomized trial to evaluate how well MBSR compared to a first-line psychological intervention for social anxiety disorder (SAD). Fifty-three patients with DSM-IV generalized SAD were randomized to an 8-week course of MBSR or 12 weekly sessions of cognitive-behavioral group therapy (CBGT). Although patients in both treatment groups improved, patients receiving CBGT had significantly lower scores on clinician- and patient-rated measures of social anxiety. Response and remission rates were also significantly greater with CBGT. Both interventions were comparable in improving mood, functionality and quality of life. The results confirm that CBGT is the treatment of choice of generalized SAD and suggest that MBSR may have some benefit in the treatment of generalized SAD.     

Predictors and consequences of sudden gains in transdiagnostic cognitive-behavioural therapy for anxiety disorders

Sudden gains—substantial stable symptom improvements between consecutive therapy sessions—are a common phenomenon. As condensed points of change, examination of sudden gains can provide insight into mechanisms of therapeutic change. This study investigated the association between sudden gains and cognitive change, therapeutic alliance, and/or client engagement in transdiagnostic group cognitive-behavioural therapy for anxiety disorders. Of 58 treatment initiators, 21% (n = 12) exhibited a sudden gain. Consistent with previous research, sudden gainers demonstrated significantly greater pre- to post-treatment symptom improvement than non-sudden gainers. Observational coding of therapy sessions found that sudden gains were associated with elevated levels of cognitive change and client engagement in the pre-gain session, and elevated levels of cognitive change and therapeutic alliance in the post-gain session. However, these results varied by use of within- and between-subject control comparisons, highlighting the value using a dual control methodology. In context of previous research, the results on cognitive change replicate previous findings in depressive populations, and clarify mixed findings in anxiety populations. The results on therapeutic alliance replicate previous findings for the first time in an anxiety sample, although the between-subject control comparisons revealed complexity previously undetected. This study was also the first to investigate and thus establish the relation between client engagement and sudden gains.     

Therapist empathy,homework compliance,and outcome in cognitive behavioral therapy for generalized anxiety disorder: partitioning within- and between-therapist effects

Although client-perceived therapist empathy relates to positive therapy outcomes, including in cognitive behavioral therapy (CBT), little is known about how empathy exerts its ameliorative effect. One possible way is by promoting clients’ subsequent homework compliance, a variable that also predicts positive outcomes in CBT. The present study sought to investigate simultaneously, in the context of 43 therapist–client dyads receiving 15 sessions of CBT for generalized anxiety disorder, (1) the association of early client-perceived therapist empathy (averaged over sessions 1, 3, 5) with mid-treatment client homework compliance (averaged over sessions 6, 8, 10); (2) the association of mid-treatment homework compliance on client posttreatment worry severity; and (3) the indirect effect of early perceived therapist empathy on posttreatment worry through mid-treatment homework compliance. Given that clients were nested within therapists, we examined both within- and between-therapist differences in clients’ ratings of therapist empathy and homework compliance, and tested both of these indices as predictors of the relevant dependent variables in a multilevel model. At the within-therapist level (i.e., differences between clients within a given therapist’s caseload), greater early empathy was associated with greater mid-treatment homework compliance. At the between-therapist level (i.e., differences between therapists across all of their cases), greater between-therapist homework compliance was related to lower posttreatment worry. Finally, homework compliance was not found to mediate the relationship between empathy and posttreatment outcome. The results underscore the importance of parsing client and therapist effects, and are discussed with regard to their training and research implications.     

Cost-effectiveness of Internet-based cognitive behavior therapy vs. cognitive behavioral group therapy for social anxiety disorder: results from a randomized controlled trial

Social anxiety disorder (SAD) is highly prevalent and associated with a substantial societal economic burden, primarily due to high costs of productivity loss. Cognitive behavior group therapy (CBGT) is an effective treatment for SAD and the most established in clinical practice. Internet-based cognitive behavior therapy (ICBT) has demonstrated efficacy in several trials in recent years. No study has however investigated the cost-effectiveness of ICBT compared to CBGT from a societal perspective, i.e. an analysis where both direct and indirect costs are included. The aim of the present study was to investigate the cost-effectiveness of ICBT compared to CBGT from a societal perspective using a prospective design. We conducted a randomized controlled trial where participants with SAD were randomized to ICBT (n = 64) or CBGT (n = 62). Economic data were assessed at pre-treatment, immediately following treatment and six months after treatment. Results showed that the gross total costs were significantly reduced at six-month follow-up, compared to pre-treatment in both treatment conditions. As both treatments were equivalent in reducing social anxiety and gross total costs, ICBT was more cost-effective due to lower intervention costs. We conclude that ICBT can be more cost-effective than CBGT in the treatment of SAD and that both treatments reduce societal costs for SAD.     

Changes in proposed mechanisms of action during an acceptance-based behavior therapy for generalized anxiety disorder

Based on the theory that generalized anxiety disorder (GAD) is maintained through a reactive and fused relationship with one's internal experiences and a tendency towards experiential avoidance and behavioral restriction, an acceptance-based behavior therapy (ABBT) was developed to specifically target these elements. Since ABBT has been shown to be an efficacious treatment in previous studies, the current study focuses on proposed mechanisms of change over the course of therapy. Specifically, the current study focuses on session-by-session changes in two proposed mechanisms of change: acceptance of internal experiences and engagement in meaningful activities. Overall, clients receiving ABBT reported an increase in the amount of time spent accepting internal experiences and engaging in valued activities. Change in both acceptance and engagement in meaningful activities was related to responder status at post-treatment and change in these two proposed mechanisms predicted outcome above and beyond change in worry. In addition, change in acceptance was related to reported quality of life at post-treatment.     

Brief report: sudden gains in cognitive-behavioral group therapy and group psychotherapy for social anxiety disorder among college students

The present study examined sudden gains (SGs; large symptom improvements between adjacent treatment sessions) and its association with treatment outcome in a randomized-controlled trial comparing cognitive-behavioral group therapy (CBGT) versus group psychotherapy (GPT; designed to incorporate only non-specific factors) for social anxiety disorder (SAD). SAD symptoms were assessed after each treatment session in a sample of 45 college students. Independent assessors evaluated symptom severity at baseline, post-treatment and follow-up. A total of 10 (22.2%) participants experienced SGs during treatment. No differences were found in symptom improvement at post-treatment or follow-up between individuals with and without SGs. SGs appeared at similar rates across both treatments but were associated with greater improvements at post-treatment and follow-up in GPT compared to CBGT. Majority of SGs in CBGT occurred early in treatment before the provision of specific treatment techniques. These results suggest that non-specific treatment factors may be important in promoting SGs.     

The impact of cognitive behavioral therapy on post event processing among those with social anxiety disorder

Individuals with social anxiety are prone to engage in post event processing (PEP), a post mortem review of a social interaction that focuses on negative elements. The extent that PEP is impacted by cognitive behavioral therapy (CBT) and the relation between PEP and change during treatment has yet to be evaluated in a controlled study. The current study used multilevel modeling to determine if PEP decreased as a result of treatment and if PEP limits treatment response for two types of cognitive behavioral treatments, a group-based cognitive behavioral intervention and individually based virtual reality exposure. These hypotheses were evaluated using 91 participants diagnosed with social anxiety disorder. The findings suggested that PEP decreased as a result of treatment, and that social anxiety symptoms for individuals reporting greater levels of PEP improved at a slower rate than those with lower levels of PEP. Further research is needed to understand why PEP attenuates response to treatment.
