Virtual reality in the treatment of spider phobia: a controlled study

This study explored whether virtual reality (VR) exposure therapy was effective in the treatment of spider phobia. We compared a treatment condition vs. a waiting list condition in a between group design with 23 participants. Participants in the VR treatment group received an average of four one-hour exposure therapy sessions. VR exposure was effective in treating spider phobia compared to a control condition as measured with a Fear of Spiders questionnaire, a Behavioural Avoidance Test (BAT), and severity ratings made by the clinician and an independent assessor. Eighty-three percent of patients in the VR treatment group showed clinically significant improvement compared with 0% in the waiting list group, and no patients dropped out. This study shows that VR exposure can be effective in the treatment of phobias.     

Brief cognitive therapy for social phobia: a case series

Social phobia is a common and disabling anxiety disorder. The most effective psychological treatments for social phobia are cognitive therapy and exposure. However, the degree of improvement across these treatments is variable, and their implementation is costly and time-consuming. This study aimed to conduct a preliminary clinical evaluation of the effectiveness of a brief, new form of cognitive therapy based on a recent cognitive model of social phobia. Six consecutively referred patients with social phobia were treated using established single case series methodology. Brief cognitive therapy was effective with all patients demonstrating clinically significant improvements in all measures. Treatment gains were maintained at follow-up. The mean number of treatment sessions delivered was 5.5 and improvements compare favourably with previous treatment studies. Brief cognitive therapy for social phobia appears promising and it is potentially cost-effective. Future randomised and controlled evaluations of this brief treatment are warranted.     

Effectiveness of cognitive behavioural group therapy for social phobia in a community clinic: a benchmarking study

This study used a benchmarking strategy to investigate the transportability of cognitive behavioural group therapy (CBGT) for social phobia to a community mental health clinic. The influence of common exclusion criteria on effect sizes was also examined. Patients (N=153) attended seven 4-h sessions of CBGT, which resulted in significant reductions in symptoms of social anxiety and depression. Effect sizes compared favourably to previous efficacy and effectiveness studies of both group and individual treatment. More than half of the treatment completers achieved reliable change. One-third achieved clinically significant change (CSC) on the Social Phobia Scale and the Beck Depression Inventory, but fewer achieved CSC on the Social Interaction and Anxiety Scale. Restricting the sample on the basis of depression symptoms, age above or below 50 years, comorbidity, alcohol problems, or student status did not significantly moderate effect sizes for social anxiety. It is concluded that CBGT is effective within community mental health clinics.     

Cognitive therapy for social phobia: individual versus group treatment

Cognitive-behavioural group treatment is the treatment of choice for social phobia. However, as not all patients benefit, an additional empirically validated psychological treatment would be of value. In addition, few studies have examined whether a group treatment format is more effective than an individual treatment format. A randomized controlled trial addressed these issues by comparing individual cognitive therapy, along the lines advocated by Clark and Wells (Clark, D.M. and Wells, A., 1995. A cognitive model of social phobia. In: R. G. Heimberg, M. Liebowitz, D. Hope and F. Schneier (Eds.), Social Phobia: Diagnosis, assessment, and treatment (pp. 69-93). New York: Guilford.), with a group version of the treatment and a wait-list control condition. 71 patients meeting DSM-IV criteria for social phobia participated in the trial, 65 completed the posttreatment assessment and 59 completed a six-month follow-up. Social phobia measures indicated significant pretreatment to posttreatment improvement in both individual and group cognitive therapy. Individual cognitive therapy was superior to group cognitive therapy on several measures at both posttreatment and follow-up. The effects of treatment on general measures of mood and psychopathology were less substantial than the effects on social phobia. The results suggest that individual cognitive therapy is a specific treatment for social phobia and that it's effectiveness may be diminished by delivery in a group format.     

Intensive cognitive behavioural group treatment for social phobia: a pilot study

The aim of this pilot study was to examine the effectiveness of an intensive form of cognitive behavioural group treatment practised routinely in a psychiatric clinic. A total of 27 outpatients with social phobia of long duration were assigned to a 41-hour treatment administered over 2 periods of 3.5 and 4.5 days, 1 week apart. Four groups, each comprising 6-8 patients, participated in the study. All except 1 patient (26/27) completed the treatment and 20 patients participated in all follow-up sessions after 3, 6 and 12 months. Treatment significantly reduced fear and avoidance of social interaction and performance, anticipatory anxiety and symptoms' influence on daily life. Follow-up assessments indicated maintained or increased improvement from post-test to 1 year and large sensitivity to treatment at both post-test and 1 year. Of the patients in the study, 85% were taking a prescribed drug, and 70% had taken medication for at least 1 year before they entered the treatment. At 1-year follow-up 52% had discontinued medication.     

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.     

Integrating cognitive bias modification into a standard cognitive behavioural treatment package for social phobia: A randomized controlled trial

ObjectiveThe aim of the current study was to integrate recent developments in the retraining of attentional biases towards threat into a standard cognitive behavioural treatment package for social phobia.Method134 participants (M age – 32.4: 53% female) meeting DSM-IV criteria for social phobia received a 12-week cognitive behavioural treatment program. They were randomly allocated to receive on a daily basis using home practice, either an additional computerised probe procedure designed to train attentional resource allocation away from threat, or a placebo variant of this procedure. Measures included diagnostic severity, social anxiety symptoms, life interference, and depression as well as state anxiety in response to a laboratory social threat.ResultsAt the end of treatment there were no significant differences between groups in attentional bias towards threat or in treatment response (all p's > 0.05). Both groups showed similar and highly significant reductions in diagnostic severity, social anxiety symptoms, depression symptoms, and life interference at post-treatment that was maintained and in most cases increased at 6 month follow-up (uncontrolled effect sizes ranged from d = 0.34 to d = 1.90).ConclusionsThe current results do not indicate that integration of information processing-derived attentional bias modification procedures into standard treatment packages as conducted in this study augments attentional change or enhances treatment efficacy. Further refinement of bias modification techniques, and better methods of integrating them with conventional approaches, may be needed to produce better effects.     

Mindfulness and acceptance-based group therapy versus traditional cognitive behavioral group therapy for social anxiety disorder: A randomized controlled trial

Recent research has supported the use of mindfulness and acceptance-based interventions for Social Anxiety Disorder (SAD).     

Mindfulness-based cognitive therapy as a treatment for chronic depression: A preliminary study

This pilot study investigated the effectiveness of Mindfulness-Based Cognitive Therapy (MBCT), a treatment combining mindfulness meditation and interventions taken from cognitive therapy, in patients suffering from chronic-recurrent depression. Currently symptomatic patients with at least three previous episodes of depression and a history of suicidal ideation were randomly allocated to receive either MBCT delivered in addition to treatment-as-usual (TAU; N = 14 completers) or TAU alone (N = 14 completers). Depressive symptoms and diagnostic status were assessed before and after treatment phase. Self-reported symptoms of depression decreased from severe to mild levels in the MBCT group while there was no significant change in the TAU group. Similarly, numbers of patients meeting full criteria for depression decreased significantly more in the MBCT group than in the TAU group. Results are consistent with previous uncontrolled studies. Although based on a small sample and, therefore, limited in their generalizability, they provide further preliminary evidence that MBCT can be used to successfully reduce current symptoms in patients suffering from a protracted course of the disorder.     

Generalized social phobia versus avoidant personality disorder: a commentary on three studies.

The findings of Herbert, Hope, and Bellack (1992), Holt, Heimberg, and Hope (1992), and Turner, Beidel, and Townsley (1992) are largely consistent. Avoidant personality disorder and generalized social phobia appear to be overlapping constructs that have only minor differences with respect to severity of dysfunction. This commentary addresses the implications of the findings with respect to the validity of the categorical distinction in the Diagnostic and Statistical Manual of Mental Disorders (rev. 3rd ed.; American Psychiatric Association, 1987) between avoidant personality and generalized social phobia, revisions of their respective diagnostic criteria, and their reclassification as either an anxiety or a personality disorder. Methodological and substantive suggestions for future research are also discussed.     

Assessing post-event processing after social situations: a measure based on the cognitive model for social phobia

In their cognitive model of social phobia, Clark and Wells (1995) described a process called post-event processing that is characterized by prolonged ruminative and negative thinking about a past social event. Referring to this concept, Rachman and colleagues (2000) developed a questionnaire that has been used in several studies subsequently (Post-Event Processing Questionnaire (PEPQ)). Our aim was to examine a German version of the PEPQ and, where necessary, modify this measure. In Study 1 (N=130 students), we inspected the psychometric properties of the German version of the PEPQ. According to the item analyses, problematic items were identified and eliminated or reformulated. To map aspects of post-event processing that were missing in the original questionnaire, new items were developed. In Study 2, the psychometric properties of the revised instrument were analyzed in a sample of students (N=268).The revised instrument showed excellent internal consistency and a meaningful pattern of correlations with anxiety, depression, and dysfunctional self-consciousness. With regard to the factorial structure of the construct, our data suggest that a four-factorial model may be more appropriate than the one-dimensional structure proposed by Rachman and colleagues.     

A randomised controlled trial of cognitive-behaviour therapy for clinical perfectionism: a preliminary study

Perfectionism can be a problem in its own right and it can impede the progress of treatment of Axis I disorders. This study reports on a preliminary randomised controlled trial of cognitive-behaviour therapy (CBT) for "clinical perfectionism". Twenty participants were randomly assigned to either immediate treatment (IT) (n=10) or a wait list (NL) (n=10). Treatment consisted of ten sessions of CBT over eight weeks. Two participants did not complete the follow-up assessments (10%). Fifteen of the original 20 participants (75%) were clinically significantly improved after treatment and the effect size was large (1.8). Treatment gains were maintained at 8-week and 16-week follow-up.     

Social skills, social outcomes, and cognitive features of childhood social phobia.

Social skills, social outcomes, self-talk, outcome expectancies, and self-evaluation of performance during social-evaluative tasks were examined with 27 clinically diagnosed social phobic children ages 7-14 and a matched nonclinical group. Results showed that, compared with their nonanxious peers, social phobic children demonstrated lower expected performance and a higher level of negative self-talk on social-evaluative tasks. In addition, social phobic children showed social skills deficits as assessed by self- and parent report, an assertiveness questionnaire, and direct behavioral observation. Furthermore, compared with the control group, social phobic children were rated by themselves and others as significantly less socially competent with peers and were found to be less likely to receive positive outcomes from peers during behavioral observation. Implications for the assessment and treatment of childhood social phobia are discussed.     

Group cohesion in cognitive-behavioral group therapy for social phobia

Cognitive-behavior therapy (CBT) for Social Phobia is effective in both group and individual formats. However, the impact of group processes on treatment efficacy remains relatively unexplored. In this study we examined group cohesion ratings made by individuals at the midpoint and endpoint of CBT groups for social phobia. Symptom measures were also completed at the beginning and end of treatment. We found that cohesion ratings significantly increased over the course of the group and were associated with improvement over time in social anxiety symptoms, as well as improvement on measures of general anxiety, depression, and functional impairment. In conclusion, findings are consistent with the idea that changes in group cohesion are related to social anxiety symptom reduction and, therefore, speak to the importance of nonspecific therapeutic factors in treatment outcome.     

A randomized pilot study of mindfulness‐based cognitive therapy and group cognitive‐behavioral therapy for young adults with social phobia

Piet, J., Hougaard, E., Hecksher, M. S., & Rosenberg, N. K. (2010). A randomized pilot study of mindfulness‐based cognitive therapy and group cognitive‐behavioral therapy for young adults with social phobia. Scandinavian Journal of Psychology, 51, 403–410. Twenty‐six young participants, 18–25 years, with social phobia (SP) were randomly assigned to eight 2‐hour sessions of group mindfulness‐based cognitive therapy (MBCT) and twelve 2‐hour sessions of group cognitive‐behavioral therapy (CBT) in a crossover design with participants receiving treatments in reversed order. Outcome was assessed after treatments, and at 6‐ and 12‐month follow‐ups. MBCT achieved moderate‐high pre‐post effect sizes (d = 0.78 on a composite SP measure), not significantly different from, although numerical lower than those of CBT (d = 1.15). Participants in both groups further improved in the periods following their first and second treatment until 6‐months follow‐up (pre‐follow‐up ds = 1.42 and 1.62). Thus, MBCT might be a useful, low cost treatment for SP, although, probably, less efficacious than CBT.     

Imagery and interpretations in social phobia: support for the combined cognitive biases hypothesis

Cognitive-behavioral models of clinical problems typically postulate a role for the combined effects of different cognitive biases in the maintenance of a given disorder. It is striking therefore that research has tended to examine cognitive biases in isolation rather than assessing how they work together to maintain psychological dysfunction. The combined cognitive biases hypothesis presented here suggests that cognitive biases influence each another and can interact to maintain a given disorder. Furthermore, it is proposed that the combined effects of cognitive biases may have a greater impact on sustaining a given disorder than if the biases operated in isolation. The combined cognitive biases hypothesis is examined in relation to imagery and interpretation in social phobia. Individuals with social phobia experience negative images of themselves performing poorly in social situations, and they also interpret external social information in a less positive way than those without social anxiety. Evidence of a reciprocal relationship between imagery and interpretations is presented, and the mechanisms underlying the combined effects are discussed. Clinical implications and the potential utility of examining the combined influence of other cognitive biases are highlighted.
