Changing core beliefs with trial-based cognitive therapy may improve quality of life in social phobia: a randomized study

Abstract

Objective:

To determine whether there are differences in quality of life (QoL) improvement after treatment with the trial-based thought record (TBTR) versus conventional cognitive therapy (CCT) in patients with social anxiety disorder (SAD).

Method:

A randomized trial comparing TBTR with a set of CCT techniques, which included the standard 7-column dysfunctional thought record (DTR) and the positive data log (PDL) in patients with SAD, generalized type.

Results:

Repeated measures analysis of variance (ANOVA) revealed a significant time effect in the general health, vitality, social functioning, and mental health domains of the Short Form 36. It also indicated significant treatment effects on the bodily pain, social functioning, role-emotional, and mental health domains, with higher scores in the TBTR group. One-way analysis of covariance (ANCOVA), using pretreatment values as covariates, showed that TBTR was associated with significantly better QoL post-treatment (bodily pain, social functioning and role-emotional) and at follow-up (role-emotional). A significant treatment effect on the role-emotional domain at 12-month follow-up denoted a sustained effect of TBTR relative to CCT.

Conclusion:

This study provided preliminary evidence that TBTR is at least as effective as CCT in improving several domains of QoL in SAD, specifically when the standard 7-column DTR and the PDL are used.

Introduction

Social anxiety disorder (SAD), also called social phobia, is a chronic and disabling condition. It is assumed to be the most common anxiety disorder, with a lifetime prevalence of 12%,11. Kessler RC, Berglund P, Demler O, Jin R, Merikangas KR, Walters EE. Lifetime prevalence and age-of-onset distributions of DSM-IV disorders in the National Comorbidity Survey Replication. Arch Gen Psychiatry. 2005;62:593-602. and a 12-month prevalence of 7%. A total of 70% of cases are categorized as severe or moderate.22. Kessler RC, Chiu WT, Demler O, Merikangas KR, Walters EE. Prevalence, severity, and comorbidity of 12-month DSM-IV disorders in the National Comorbidity Survey Replication. Arch Gen Psychiatry. 2005;62:617-27. Cognitive behavioral therapy (CBT) has been shown to be effective in SAD,33. Acarturk C, Cuijpers P, van Straten A, de Graaf R. Psychological treatment of social anxiety disorder: a meta-analysis. Psychol Med. 2009;39:241-54. but 40 to 50% of patients show little or no improvement after treatment.44. Heimberg RG, Liebowitz MR, Hope DA, Schneier FR, Holt CS, Welkowitz LA, et al. Cognitive behavioral group therapy vs phenelzine therapy for social phobia: 12-week outcome. Arch Gen Psychiatry. 1998;55:1133-41. Although CBT has recently been refined to target more specific cognitive processes believed to maintain and exacerbate symptomatology,55.

Quality of life (QoL) is highly compromised in SAD.8. Safren SA, Heimberg RG, Brown EJ, Holle C. Quality of life in social phobia. Depress Anxiety. 1996-1997;4:126-33. 9. Wittchen HU, Fuetsch M, Sonntag H, Muller N, Liebowitz M. Disability and quality of life in pure and comorbid social phobia. Findings from a controlled study. Eur Psychiatry. 2000;15:46-58. 8-1010. Simon NM, Otto MW, Korbly NB, Peters PM, Nicolaou DC, Pollack MH. Quality of life in social anxiety disorder compared with panic disorder and the general population. Psychiatr Serv. 2002;53:714-8. In a sample of predominantly untreated patients with SAD symptoms recruited over two decades, QoL was significantly reduced in both pure and comorbid SAD, especially in scales measuring general health, role-limitations due to emotional health, social functioning, general mental health, and vitality. Together, at least 50% of all patients suffering from moderate and severe SAD had a markedly reduced QoL, compared to 4.6% in the control group.99. Wittchen HU, Fuetsch M, Sonntag H, Muller N, Liebowitz M. Disability and quality of life in pure and comorbid social phobia. Findings from a controlled study. Eur Psychiatry. 2000;15:46-58. Studies suggest that even patients with SAD who do not have significant comorbid depression or anxiety are substantially impaired in mental health and social functioning.1010. Simon NM, Otto MW, Korbly NB, Peters PM, Nicolaou DC, Pollack MH. Quality of life in social anxiety disorder compared with panic disorder and the general population. Psychiatr Serv. 2002;53:714-8.

Studies assessing QoL in SAD after CBT are scarce. However, the impact of SAD on self-perceived QoL immediately after treatment88. Safren SA, Heimberg RG, Brown EJ, Holle C. Quality of life in social phobia. Depress Anxiety. 1996-1997;4:126-33. and at 6-month follow-up have been investigated.1111. Eng W, Coles ME, Heimberg RG, Safren SA. Domains of life satisfaction in social anxiety disorder: relation to symptoms and response to cognitive-behavioral therapy. J Anxiety Disord. 2005;19:143-56. Studies suggested that patients with SAD had very low self-rated QoL scores, which varied with symptomatic distress and impairment. This research has also found that socially anxious patients showed significant improvement in self-perceived QoL immediately after cognitive-behavioral group therapy (CBGT).88. Safren SA, Heimberg RG, Brown EJ, Holle C. Quality of life in social phobia. Depress Anxiety. 1996-1997;4:126-33. Such gains were maintained from post-treatment to 6-month follow-up.1111. Eng W, Coles ME, Heimberg RG, Safren SA. Domains of life satisfaction in social anxiety disorder: relation to symptoms and response to cognitive-behavioral therapy. J Anxiety Disord. 2005;19:143-56. A more recent study of SAD patients who received 12 to 20 2-hour CBGT sessions concluded that, although symptoms of SAD and some aspects of QoL improved for up to 12 months after CBGT, the social functioning domain did not change, suggesting the need for better treatments for this condition.1212. Watanabe N, Furukawa TA, Chen J, Kinoshita Y, Nakano Y, Ogawa S, et al. Change in quality of life and their predictors in the long-term follow-up after group cognitive behavioral therapy for social anxiety disorder: a prospective cohort study.

The trial-based thought record (TBTR),1313. de-Oliveira IR. Trial-Based Thought Record (TBTR): preliminary data on a strategy to deal with core beliefs by combining sentence reversion and the use of analogy with a judicial process. Rev Bras Psiquiatr. 2008;30:12-8. a novel approach used in trial-based cognitive therapy (TBCT),1414. de-Oliveira IR. Common Language for Psychotherapy (CLP) procedures [Internet]. Trial-based thought record. 2011 [cited 2013 Jul 2]. http://www.commonlanguagepsychotherapy.org/fileadmin/user_upload/Accepted_procedures/trial-based.pdf
http://www.commonlanguagepsychotherapy.o...
was developed to address negative core beliefs (CBs) in CBT. In TBTR, the therapist engages the patient in a simulation of a legal trial, stimulating the activation of negative CBs and associated negative emotions, with the aim of reducing their effect with disconfirming evidence. The repeated use of TBTR may eventually deactivate negative dysfunctional CBs, as more credible evidence in support of functional CBs is produced.1515. de-Oliveira IR. Use of the trial-based thought record to change negative core beliefs. In: Standard and innovative strategies in cognitive behavior therapy. de-Oliveira IR, editor. Rijeka: InTech; 2012. p. 35-60.

In the present study, we hypothesized that TBTR would reduce symptoms of social anxiety by restructuring CBs. The objective was to assess the short- (4-month) and long-term (12-month) efficacy of TBTR in SAD. Findings regarding QoL are reported in the present study, while a detailed description of results involving other clinical outcomes has been previously published.1616. de-Oliveira IR, Powell VB, Wenzel A, Caldas M, Seixas C, Almeida C, et al. Efficacy of the trial-based thought record, a new cognitive therapy strategy designed to change core beliefs, in social phobia. J Clin Pharm Ther. 2012;37:328-34.

Methods

The method used in this study is described in greater detail elsewhere,1616. de-Oliveira IR, Powell VB, Wenzel A, Caldas M, Seixas C, Almeida C, et al. Efficacy of the trial-based thought record, a new cognitive therapy strategy designed to change core beliefs, in social phobia. J Clin Pharm Ther. 2012;37:328-34. but a brief description of the main methodological aspects is provided below.

Advertisements in local newspapers and interviews about social anxiety given by the first author to local radio and television stations were used to recruit the patients. Only people who met DSM-IV criteria for generalized SAD were included in the study. All patients were assessed at an anxiety disorders clinic in a university teaching hospital.

Forty-seven patients who completed initial assessments were randomized to treatment, with 25 of these allocated to TBTR and 22 to conventional cognitive therapy (CCT) (Figure 1). However, differently from the clinical outcomes described elsewhere,1414. de-Oliveira IR. Common Language for Psychotherapy (CLP) procedures [Internet]. Trial-based thought record. 2011 [cited 2013 Jul 2]. http://www.commonlanguagepsychotherapy.org/fileadmin/user_upload/Accepted_procedures/trial-based.pdf
http://www.commonlanguagepsychotherapy.o...
the final sample for QoL analyses in the present study included only the 16 patients in the TBTR group and 14 in the CCT group who had attended all 12 treatment sessions.

The study was a two-arm randomized trial comparing TBTR with a set of CCT techniques, which included the standard dysfunctional thought record (DTR) and the positive data log (PDL).1717. Tompkins MA, Persons JB, Davidson J. Cognitive-behavior therapy for depression: schema change methods [DVD]. Washington: American Psychological Association; 2006. [cited 2010 Jun 24]. http://www.apa.org/pubs/videos/4310776.aspx

The researcher conducting randomization was blind to the treatment protocol. After signing the informed consent form, participants were assessed with the Mini International Neuropsychiatric Interview (MINI).1818. Sheehan DV, Lecrubier Y, Sheehan KH, Amorim P, Janavs J, Weiller E, et al. The Mini-International Neuropsychiatric Interview (M.I.N.I.): the development and validation of a structured diagnostic psychiatric interview for DSM-IV and ICD-10. J Clin Psychiatry. 1998;59:22-33;quiz 34-57. Participants of any gender or ethnic group, aged 18 to 70, able to read and write, who fulfilled DSM-IV criteria for SAD, generalized type were included in the study. Exclusion criteria comprised major comorbid Axis I psychiatric disorders (e.g., major depression, schizophrenia, bipolar disorder), alcohol or substance use/abuse in the past 6 months, suicide risk, or presently being in psychotherapy.

Treatment consisted of 10 weekly 1-hour individual sessions of either TBTR (experimental group) or CCT, and two 1-hour biweekly sessions in the last 4 weeks. Sessions 1 to 5 in both treatment conditions involved psychoeducation about the cognitive model and cognitive distortions. From session 6 onward, both treatments focused on restructuring CBs with either the TBTR or CCT, specifically the standard 7-column DTR and the PDL. TBTR techniques differed from the CCT techniques in that (in addition to simulating a legal trial) patients were actively stimulated to disqualify the evidence that did not support the negative CBs (e.g., "I am awkward"). Afterwards, by means of a sentence-reversal approach, the therapist engaged the patients in a second round exploring the evidence that supported the positive CBs (e. g., "I am normal"). TBTR also differed from the CCT techniques in that in TBTR the new positive CBs were uncovered by means of the upward arrow technique. From sessions 6 through 12, both approaches (TBTR and CCT) were focused on uncovering and bolstering the new positive CBs. Although the DTR was not designed by Beck et al.1919. Beck AT, Rush AJ, Shaw BF, Emery G. Cognitive therapy of depression. New York: Guilford Press; 1979. or modified by Greenberger and Padesky2020. Greenberger DG, Padesky CA. Mind over mood. New York: Guilford Press; 1995. to change CBs, it is one of the most commonly used techniques for this purpose. Furthermore, the PDL was specifically designed to change CBs,1717. Tompkins MA, Persons JB, Davidson J. Cognitive-behavior therapy for depression: schema change methods [DVD]. Washington: American Psychological Association; 2006. [cited 2010 Jun 24]. http://www.apa.org/pubs/videos/4310776.aspx
http://www.apa.org/pubs/videos/4310776.a...
which is why it was included in the contrast group.

All the therapists were psychologists and certified cognitive therapists previously trained in both approaches. Therapists had attended a 2-year cognitive therapy specialization course organized by two of the authors (IRO and VBP). They were invited to participate in the study because they were among those who had the best performance during training. The course included 384 h of theory, 60 h of clinical experience with patients and 86 h of supervision. Also, knowledge and competence were assessed through a total of 23 monthly written exams throughout the course. In addition to having completed the specialization course, all therapists had at least 1 year of experience in private practice as certified cognitive therapists at the time the clinical trial began. All therapists received training together, so that therapists in both arms (i.e., TBCT and CCT) had equivalent experience and expertise in both approaches.

Assessment of QoL was performed with the Brazilian version2121. Ciconelli RM, Ferraz MB, Santos W, Meinão I, Quaresma MR. [Brazilian-Portuguese version of the SF-36. A reliable and valid quality of life outcome measure]. Rev Bras Reumatol. 1999;39:143-50. of the Short Form 36 (SF-36),2222. Ware JE Jr., Sherbourne CD. The MOS 36-item short-form health survey (SF-36). I. Conceptual framework and item selection. Med Care. 1992;30:473-83. a 36-item self-report questionnaire addressing the following domains: physical functioning, role-physical, bodily pain, general health perception, vitality, social functioning, role-emotional and mental health. The questionnaire was administered at pre-treatment, post-treatment (4 months), and 12-month follow-up.

All patients who provided at least two SF-36 assessments (baseline and post-treatment) were included in the analyses (completers). However, a last observed carried forward (LOCF) intention-to-treat approach was employed for the 12-month follow-up analyses, so that analyses included completers at post-treatment and intention-to-treat (ITT) at follow-up.

A mixed (repeated measures) analysis of variance (ANOVA) was implemented to evaluate the efficacy of the interventions, with the number of assessments (pre-treatment, post-treatment and follow-up) being computed as a within-subject factor (time) and treatment modality (TBCT and CCT) as a between-subjects factor. We also conducted a one-way analysis of covariance (ANCOVA) using baseline scores as covariates. Level of significance was set at .05. Analyses were conducted with the SPSS 17.0 software.

Within-subjects Cohen's d effect sizes were also calculated.2323. Borenstein M, Hedges LV, Higgins JPT, Rothstein HR. Introduction to meta-analysis. Chichester: John Wiley & Sons; 2009. Effect sizes (ESs) of 0-0.32 were considered small, scores of 0.33-0.55 were considered moderate, while those between 0.56 and 1.2 were interpreted as large. ESs greater than 1.2 were assumed to be very large.

Results

A mixed (repeated measures) ANOVA revealed a significant time effect in the general health, vitality, social functioning and mental health domains of QoL, and the results of this analysis are displayed in Table 1. This table also displays significant treatment effects in the bodily pain, social functioning, role-emotional, and mental health domains, with higher scores in the TBTR group. A one-way ANCOVA, taking pre-treatment values as covariates, showed that TBTR led to significantly better post-treatment (bodily pain, social functioning and role-emotional) and follow-up (role-emotional) results than the CCT techniques. There was also a significant treatment effect on the role-emotional domain at follow-up, showing a sustained effect of TBTR relative to CCT.

Discussion

The present study shows that both CCT and TBTR, a novel cognitive behavioral approach,2424. de-Oliveira IR. Kafka's trial dilemma: proposal of a practical solution to Joseph K.'s unknown accusation. Med Hypotheses. 2011;77:5-6. improved several domains of QoL, namely general health, vitality, social functioning, and mental health. As far as we know, this is the first study comparing QoL measures following a new CBT approach with standard CBT techniques in SAD. Moreover, we are aware of no studies comparing the long-term outcomes of different CBT approaches.

An earlier study1212. Watanabe N, Furukawa TA, Chen J, Kinoshita Y, Nakano Y, Ogawa S, et al. Change in quality of life and their predictors in the long-term follow-up after group cognitive behavioral therapy for social anxiety disorder: a prospective cohort study. BMC Psychiatry. 2010;10:81. of SAD patients found modest improvement in aspects of QoL following treatment, which were maintained at the 12-month follow-up. The Cohen's d ESs seen in the CCT group in the present study (Table 2) were similar or slightly larger than those found in the aforementioned study.1212. Watanabe N, Furukawa TA, Chen J, Kinoshita Y, Nakano Y, Ogawa S, et al. Change in quality of life and their predictors in the long-term follow-up after group cognitive behavioral therapy for social anxiety disorder: a prospective cohort study. BMC Psychiatry. 2010;10:81. However, TBTR had large to very large ESs at post-treatment in the mental health (ES = 1.09) and social functioning (ES = 1.41) domains, as well as large ESs in the social functioning domains (ES = 0.76) at follow-up, and these results were not accomplished neither in the CCT contrast group of our study nor in that study.1212. Watanabe N, Furukawa TA, Chen J, Kinoshita Y, Nakano Y, Ogawa S, et al. Change in quality of life and their predictors in the long-term follow-up after group cognitive behavioral therapy for social anxiety disorder: a prospective cohort study. BMC Psychiatry. 2010;10:81. A possible explanation for this finding is that TBTR had a more significant effect on fear of negative evaluation (FNE) scores than CCT techniques, as shown in a previous publication of this study.1616. de-Oliveira IR, Powell VB, Wenzel A, Caldas M, Seixas C, Almeida C, et al. Efficacy of the trial-based thought record, a new cognitive therapy strategy designed to change core beliefs, in social phobia. J Clin Pharm Ther. 2012;37:328-34. The one-way ANCOVA showed a significant treatment effect (F[1, 33] = 5.47; p = 0.03) at mid-treatment and at post-treatment, with participants in the TBTR group scoring lower on FNE assessments than participants in the CCT group.

Clearly, results from this study should be interpreted in light of its limitations. Firstly, the sample size was small. Secondly, patients were recruited by means of advertisements and interviews on radio and television, which may mean this sample is not representative of the treatment-seeking SAD population, even though all participants fulfilled DSM-IV criteria for generalized SAD. Thirdly, all patients received the same intervention in the initial phase of the study (i.e., first 5 sessions), so the comparison is based on a short duration of treatment (weeks 6 to 12). Nevertheless, even with this short duration of treatment, significant differences emerged on several SF-36 domains. A final limitation was that comparison was performed with a contrast group rather than a control group. The latter would have added value to this study.

In summary, this pattern of findings allows us to conclude that TBTR is significantly more effective than CCT, specifically the standard 7-column DTR and the PDL, in improving several domains of QoL in the short- (namely bodily pain, social functioning and role-emotional) and long-term (namely role-emotional). These results suggest that it would be valuable to investigate the efficacy of TBTR, as well as the broader approach, TBCT,2424. de-Oliveira IR. Kafka's trial dilemma: proposal of a practical solution to Joseph K.'s unknown accusation. Med Hypotheses. 2011;77:5-6. in a larger sample of patients with SAD, as well as in patients with other psychiatric disorders characterized by dysfunctional CBs.2525. de-Oliveira IR, Hemmany C, Powell VB, Bonfim TD, Duran EP, Novais N, et al.
