The effectiveness of group cognitive behaviour therapy for unipolar depressive disorders

Training addiction counselors to implement CBT for depression

Many clients in publicly funded substance abuse treatment programs suffer from depression yet lack access to effective mental health treatment. This study sought to examine whether addiction counselors could be effectively trained to deliver group CBT for depression and to ascertain client perceptions of the treatment. Five counselors were trained in the therapy and treated 113 clients with depression symptoms. Counselors demonstrated high fidelity to the therapy and client perceptions of the therapy were positive. Our results suggest that training addiction counselors to deliver group CBT for depression is a promising integrated treatment approach for co-occurring depression and substance disorders.

An effectiveness trial of group cognitive behavioral therapy for patients with persistent depressive symptoms in substance abuse treatment

CONTEXT

Although depression frequently co-occurs with substance abuse, few individuals entering substance abuse treatment have access to effective depression treatment.

OBJECTIVE

The Building Recovery by Improving Goals, Habits, and Thoughts (BRIGHT) study is a community-based effectiveness trial that compared residential substance abuse treatment with residential treatment plus group cognitive behavioral therapy for depression delivered by substance abuse treatment counselors. We hypothesized that intervention clients would have improved depression and substance use outcomes compared with those of clients receiving usual care.

DESIGN

A nonrandomized controlled trial using a quasi-experimental intent-to-treat design in which 4 sites were assigned to alternate between the intervention and usual care conditions every 4 months for 2½ years.

SETTING

Four treatment programs in Los Angeles County.

PARTICIPANTS

We screened 1262 clients for persistent depressive symptoms (Beck Depression Inventory-II score >17). We assigned 299 clients to receive either usual care (n = 159) or usual care plus the intervention (n = 140). Follow-up rates at 3 and 6 months after the baseline interview were 88.1% and 86.2%, respectively, for usual care and 85.7% and 85.0%, respectively, for the intervention group.

INTERVENTION

Sixteen 2-hour group sessions of cognitive behavioral therapy for depression.

MAIN OUTCOME MEASURES

Change in depression symptoms, mental health functioning, and days of alcohol and problem substance use.

RESULTS

Intervention clients reported significantly fewer depressive symptoms (P < .001 at 3 and 6 months) and had improved mental health functioning (P < .001 at 3 months and P < .01 at 6 months). At 6 months, intervention clients reported fewer drinking days (P < .05) and fewer days of problem substance use (P < .05) on days available.

CONCLUSIONS

Providing group cognitive behavioral therapy for depression to clients with persistent depressive symptoms receiving residential substance abuse treatment is associated with improved depression and substance use outcomes. These results provide support for a new model of integrated care.

Dejian mind-body intervention on depressive mood of community-dwelling adults: a randomized controlled trial

The present study evaluated the effectiveness of a short-term mind-body intervention program on improving the depressive mood of an adult community sample. Forty adult volunteers with various degrees of depressive mood were randomly assigned to the experimental group (Dejian Mind-Body Intervention, DMBI) and control group (Cognitive-Behavioral Therapy, CBT). For each group, a total of four 90-min weekly sessions were conducted. Treatment-related changes were measured using the Beck Depression Inventory (BDI-II), an electroencephalographic indicator of positive affect (i.e., prefrontal activation asymmetry), and self-report ratings on physical health. Results indicated that both the DMBI and the CBT group demonstrated significant reduction in depressive mood. However, among individuals with moderate to severe depressive mood at baseline, only those in the DMBI but not the CBT group showed significant reduction in depressive mood. Besides, only the DMBI group demonstrated a significant increase in prefrontal activation asymmetry, suggesting increase in positive affect. While most psychological therapies for depressive mood normally take several months to show treatment effect, the present findings provided initial data suggesting that the DMBI was effective in improving depressive mood of community adults after 1 month of training.

Mindfulness-based cognitive therapy vs cognitive behaviour therapy as a treatment for non-melancholic depression

AIM

To examine the comparative effectiveness of Mindfulness-Based Cognitive Therapy (MBCT) and Cognitive Behaviour Therapy (CBT) as treatments for non-melancholic depression.

METHOD

Participants who met criteria for a current episode of major depressive disorder were randomly assigned to either an 8-week MBCT (n=19) or CBT (n=26) group therapy condition. They were assessed at pre-treatment, 8-week post-group, and 6- and 12-month follow-ups.

RESULTS

There were significant improvements in pre- to post-group depression and anxiety scores in both treatment conditions and no significant differences between the two treatment conditions. However, significant differences were found when participants in the two treatment conditions were dichotomized into those with a history of four or more episodes of depression vs those with less than four. In the CBT condition, participants with four or more previous episodes of depression demonstrated greater improvements in depression than those with less than four previous episodes. No such differences were found in the MBCT treatment condition. No significant differences in depression or anxiety were found between the two treatment conditions at 6- and 12-month follow-ups.

LIMITATIONS

Small sample sizes in each treatment condition, especially at follow-up.

CONCLUSIONS

MBCT appears to be as effective as CBT in the treatment of current depression. However, CBT participants with four or more previous episodes of depression derived greater benefits at 8-week post-treatment than those with less than four episodes.

A review on assessment and treatment for depression in malaysia

This paper aimed to review the literature on depression that focused on its assessment and treatment in Malaysia. PsycINFO, Medline, local journals were searched, and 18 published articles were included in this paper. Results indicate that research on depression in Malaysia, particularly validation studies and psychotherapy research, was weak and fragmented, with minimal empirical evidence available. Pharmacotherapy still dominated the treatment for depression, and, in terms of psychotherapy, Cognitive Behavioural Therapy (CBT) was recently practiced, but only a few studies have reported on the treatment efficacy of CBT. Major limitations of studies were noted, and, consequently, the problems that are associated with the implementation and future direction of clinical and research on depression in Malaysia were discussed. In short, the contribution of empirical research on the assessment and treatment for depression remained inconsistent and fragmented and urgently in need of further empirical investigation.

Australians living with and managing hepatitis C

This paper discusses the psychosocial impact of being diagnosed with hepatitis C virus (HCV). The paper clarifies some of the key misconceptions about the virus, especially the impact HCV has on people who have been recently diagnosed. An individual's reaction to the HCV diagnosis and the subsequent lifestyle challenges to maintain health, well-being, family, and social networks are discussed, particularly the issues surrounding mental health in respect to a recent chronic illness diagnosis and how to manage the trajectory of the illness in the community and individually. HCV disclosure and its effect on intimacy are also detailed. For people living with both a diagnosed mental illness and HCV, managing the illness can be complicated. Not only are these individuals concerned about their mental illness, its treatment, and the social stigma and discrimination associated with it, they also may be alarmed over their future physical health. The paper is preliminary to research using the psychotherapeutic approach of Cognitive Behavioural Therapy (CBT) in groups of persons with a dual diagnosis of mental illness and HCV.

Mechanisms of change in negative thinking and urinary monoamines in depressed patients during acute treatment with group cognitive behavior therapy and antidepressant medication

This naturalistic study investigated the mechanisms of change in measures of negative thinking and in 24-h urinary metabolites of noradrenaline (norepinephrine), dopamine and serotonin in a sample of 43 depressed hospital patients attending an eight-session group cognitive behavior therapy program. Most participants (91%) were taking antidepressant medication throughout the therapy period according to their treating Psychiatrists' prescriptions. The sample was divided into outcome categories (19 Responders and 24 Non-responders) on the basis of a clinically reliable change index [Jacobson, N.S., & Truax, P., 1991.

CLINICAL SIGNIFICANCE

a statistical approach to defining meaningful change in psychotherapy research. Journal of Consulting and Clinical Psychology, 59, 12-19.] applied to the Beck Depression Inventory scores at the end of the therapy. Results of repeated measures analysis of variance [ANOVA] analyses of variance indicated that all measures of negative thinking improved significantly during therapy, and significantly more so in the Responders as expected. The treatment had a significant impact on urinary adrenaline and metadrenaline excretion however, these changes occurred in both Responders and Non-responders. Acute treatment did not significantly influence the six other monoamine metabolites. In summary, changes in urinary monoamine levels during combined treatment for depression were not associated with self-reported changes in mood symptoms.

Recognizing and treating comorbid ADHD in adults with depression

The National Comorbidity Survey Replication by Kessler and colleagues found that of adult patients with major depressive disorder (MDD), 9.4% met Diagnostic and Statistical Manual of Mental Disorders, Third Edition-Revised criteria for attention-deficit/hyperactivity disorder (ADHD). Among those with dysthymia, 22.6% also met criteria for ADHD. In addition, it is estimated that approximately a third of the United States population experiences MDD symptoms at any point in time. Kessler and colleagues also conducted a retrospective study on impairment of adults with ADHD and found that ADHD has a prevalence of ∼4.4% in the US adult population, which suggests that ∼9 million US adults may have ADHD.

Clinical effectiveness of a cognitive behavioral group treatment program for anxiety disorders: a benchmarking study

Previous research has established efficacy of cognitive behavioral therapy (CBT) for anxiety disorders, yet it has not been widely assessed in routine community clinic practices. Efficacy research sacrifices external validity to achieve maximum internal validity. Recently, effectiveness research has been advocated as more ecologically valid for assessing routine clinical work in community clinics. Furthermore, there is a lack of effectiveness research in group CBT. This study aims to extend existing research on the effectiveness of CBT from individual therapy into group therapy delivery. It aimed also to examine outcome using not only symptom measures, but also measures of related symptoms, cognitions, and life quality and satisfaction. Results from a cohort of patients with various anxiety disorders demonstrated that treatment was effective in reducing anxiety symptoms to an extent comparable with other effectiveness studies. Despite this, only 43% of individuals showed reliable change, and 17% were 'recovered' from their anxiety symptoms, and the post-treatment measures were still significantly different from the level of anxiety symptoms observed in the general population.

A nonrandomized effectiveness comparison of broad-spectrum group CBT to individual CBT for depressed outpatients in a community mental health setting

Controlled trials have established the efficacy of cognitive-behavior therapy (CBT) for depression. However, the relative effectiveness of individual versus group treatment formats in real-world settings is less well established. The current study evaluated the effectiveness of group CBT (n=157) compared to individual CBT (n=77) for depressed outpatients in a naturalistic setting. Symptom improvements for depression, anxiety, and quality of life were compared between treatment formats in intent-to-treat and completer analyses. Effect sizes and rates of recovery were examined. Results showed that both individual and group CBT were effective, even in the presence of high levels of comorbidity. Whereas individual CBT was associated with larger effect sizes and significantly higher rates of recovery, group CBT compared favorably to outcomes established by past research. A broad-spectrum group CBT program may be a viable treatment option when depression symptoms are less severe and when this format of treatment delivery is desirable.

A pilot randomised controlled trial of a brief cognitive behavioural group intervention to reduce recurrence rates in late life depression

OBJECTIVES

To standardise the delivery of a brief group cognitive behaviour therapy intervention (CBT-G). To apply the intervention in a research setting and to estimate its effect on recurrence rates in recently depressed older adults, in preparation for a definitive study.

METHOD

A CBT-G therapy manual was produced and the Cognitive Therapy Rating Scale (CTS-R) modified to assess therapy delivery. Forty-five adults aged 60 and over who had met ICD-10 criteria for major depression in the previous year and were still taking antidepressant medication were randomly allocated to CBT-G/antidepressant combination or antidepressant alone. Depression severity was measured at baseline, randomisation and 6 and 12 months after start of CBT-G using the Montgomery Asberg Rating Scale for Depression (MADRS).

RESULTS AND CONCLUSION

One-year recurrence rates on the MADRS were encouragingly lower in participants receiving CBT-G [5/18 (27.8%)] compared with controls [8/18 (44.4%)] although this did not achieve statistical significance (adjusted RR 0.70 [95% CI 0.26-1.94]). In contrast, overall scores on the secondary outcome measure, the Beck Depression Inventory, increased in participants receiving CBT-G. The CBT-G manual was successfully implemented and therapy delivery achieved an overall satisfactory level of competence. We believe that evaluation of this promising intervention in a full-scale trial is warranted.
