Cost-effectiveness of cognitive-behavioural therapy for mental disorders: implications for public health care funding policy in Canada

The effect of mindfulness meditation on depressive symptoms during the COVID-19 pandemic: a systematic review and meta-analysis

Currently, 280 million people worldwide experience depression, ranking it third in the global burden of disease. The incidence of depression has risen due to the COVID-19 pandemic, making it essential to examine evidence-based practices in reducing depressive symptoms during this unprecedented time. This systematic review and meta-analysis aim to analyze randomized controlled trials during the COVID-19 pandemic that evaluated the effect of mindfulness meditation on depressive symptoms in individuals with depression. Four databases (PubMed, Embase, Web of Science, and Scopus) were searched in November 2023 using search terms including meditation, mindfulness, depression, and depressive symptoms. The meta-analysis was conducted using Review Manager 5.4 software (Cochrane Collaboration). A random model and Standard Mean Difference analysis with 95% CIs were used for continuous variables. The systematic review included 26 RCT studies. The meta-analysis showed significant effects of mindfulness meditation interventions (SMD = - 1.14; 95% CI - 1.45 to - 0.83; P < 0.001) in reducing depressive symptoms compared to comparison groups. The findings suggest a positive effect of mindfulness meditation on depressive symptoms in individuals with depression during the COVID-19 pandemic.

Action recommendations review in community-based therapy and depression and anxiety outcomes: a machine learning approach

BACKGROUND

While the positive impact of homework completion on symptom alleviation is well-established, the pivotal role of therapists in reviewing these assignments has been under-investigated. This study examined therapists' practice of assigning and reviewing action recommendations in therapy sessions, and how it correlates with patients' depression and anxiety outcomes.

METHODS

We analyzed 2,444 therapy sessions from community-based behavioral health programs. Machine learning models and natural language processing techniques were deployed to discern action recommendations and their subsequent reviews. The extent of the review was quantified by measuring the proportion of session dialogues reviewing action recommendations, a metric we refer to as "review percentage". Using Generalized Estimating Equations modeling, we evaluated the correlation between this metric and changes in clients' depression and anxiety scores.

RESULTS

Our models achieved 76% precision in capturing action recommendations and 71.1% in reviewing them. Using these models, we found that therapists typically provided clients with one to eight action recommendations per session to engage in outside therapy. However, only half of the sessions included a review of previously assigned action recommendations. We identified a significant interaction between the initial depression score and the review percentage (p = 0.045). When adjusting for this relationship, the review percentage was positively and significantly associated with a reduction in depression score (p = 0.032). This suggests that more frequent review of action recommendations in therapy relates to greater improvement in depression symptoms. Further analyses highlighted this association for mild depression (p = 0.024), but not for anxiety or moderate to severe depression.

CONCLUSIONS

An observed positive association exists between therapists' review of previous sessions' action recommendations and improved treatment outcomes among clients with mild depression, highlighting the possible advantages of consistently revisiting therapeutic homework in real-world therapy settings. Results underscore the importance of developing effective strategies to help therapists maintain continuity between therapy sessions, potentially enhancing the impact of therapy.

School-based social skills group training (SKOLKONTAKT™): a pilot randomized controlled trial

Purpose

Differences in socio-communicative behaviors contribute to social challenges for autistic learners at school and, in turn, are associated with increased risks of educational underachievement, social exclusion, and mental health issues. Given that intervention delivery in natural contexts may enhance skills generalization, build support capacities in society, and have practical advantages for youth and families, SKOLKONTAKT™ has been adapted from the clinically based social skills group training KONTAKT™ for mainstream educational settings to mitigate these risks.

Methods

A pilot, randomized controlled trial with active controls was conducted in a mainstream Swedish high school. Autistic learners and students with social skills challenges (N = 33; MAGE = 17.5) were randomized to SKOLKONTAKT™ (n = 17) or active control (n = 16). Efficacy was measured at post and follow-up (3 months) on social skills [Social Skills Group Assessment Questionnaire (SSGQ); primary outcome] by parent-, self-, and (masked) teacher-report as well as self-reported life quality and social goal attainment.

Results

Despite COVID-19 challenges, 70.6% (n = 12) completed SKOLKONTAKT™, and 87.5% (n = 14) completed control groups. SKOLKONTAKT™ improved on a series of items on SSGQ as well as subjective life quality beyond controls. A larger proportion of social goals were attained, and side-effects were of little impact and proportionally fewer in SKOLKONTAKT™.

Conclusion

SKOLKONTAKT™ is a safe, feasible, and promising intervention option for autistic learners in mainstream educational settings. A larger-scale study is desirable to confirm the effects identified in this pilot study.

Cost-Utility and Cost-effectiveness of MoodSwings 2.0, an Internet-Based Self-management Program for Bipolar Disorder: Economic Evaluation Alongside a Randomized Controlled Trial

BACKGROUND

Internet-delivered psychosocial interventions can overcome barriers to face-to-face psychosocial care, but limited evidence supports their cost-effectiveness for people with bipolar disorders (BDs).

OBJECTIVE

This study aimed to conduct within-trial cost-effectiveness and cost-utility analyses of an internet-based intervention for people with BD, MoodSwings 2.0, from an Australian health sector perspective.

METHODS

MoodSwings 2.0 included an economic evaluation alongside an international, parallel, and individually stratified randomized controlled trial comparing an internet-based discussion forum (control; group 1), a discussion forum plus internet-based psychoeducation (group 2), and a discussion forum plus psychoeducation and cognitive behavioral tools (group 3). The trial enrolled adults (aged 21 to 65 years) with a diagnosis of BD assessed by telephone using a structured clinical interview. Health sector costs included intervention delivery and additional health care resources used by participants over the 12-month trial follow-up. Outcomes included depression symptoms measured by the Montgomery-Åsberg Depression Rating Scale (MADRS; the trial primary outcome) and quality-adjusted life years (QALYs) calculated using the short-form 6-dimension instrument derived from the 12-item version of the short-form health survey. Average incremental cost-effectiveness (cost per MADRS score) and cost-utility (cost per QALY) ratios were calculated using estimated mean differences between intervention and control groups from linear mixed effects models in the base case.

RESULTS

In total, 304 participants were randomized. Average health sector cost was lowest for group 2 (Aus $9431, SD Aus $8540; Aus $1=US $0.7058) compared with the control group (Aus $15,175, SD Aus $17,206) and group 3 (Aus $15,518, SD Aus $30,523), but none was statistically significantly different. The average QALYs were not significantly different among the groups (group 1: 0.627, SD 0.062; group 2: 0.618, SD 0.094; and group 3: 0.622, SD 0.087). The MADRS scores were previously shown to differ significantly between group 2 and the control group at all follow-up time points (P<.05). Group 2 was dominant (lower costs and greater effects) compared with the control group for average incremental cost per point decrease in MADRS score over 12 months (95% CI dominated to Aus $331). Average cost per point change in MADRS score for group 3 versus the control group was dominant (95% CI dominant to Aus $22,585). Group 2 was dominant (95% CI Aus $43,000 to dominant) over the control group based on lower average health sector cost and average QALY benefit of 0.012 (95% CI -0.009 to 0.033). Group 3, compared with the control group, had an average incremental cost-effectiveness ratio of dominant (95% CI dominated to Aus $19,978).

CONCLUSIONS

Web-based psychoeducation through MoodSwings 2.0 has the potential to be a cost-effective intervention for people with BD. Additional research is needed to understand the lack of effectiveness for the addition of cognitive behavioral tools with the group 3 intervention.

Social Skills Group Training for Students with Neurodevelopmental Disabilities in Senior High School-A Qualitative Multi-Perspective Study of Social Validity

Including students with neurodevelopmental disabilities (NDDs) in regular classrooms has become a law-enforced common practice in many high- and middle-income countries. Still, without appropriate actions supporting the implementation of inclusive pedagogical practice, students with NDDs remain at increased risk for absenteeism, bullying and underachievement. There is limited knowledge on the feasibility of social skills group training (SSGT) in naturalistic settings. Using a qualitative approach, the objective of this study was to explore the lived experiences of (i) students diagnosed with autism or attention-deficit hyperactivity disorder and those showing subclinical social difficulties receiving either SSGT or active social control activities in a regular senior high school setting, (ii) teachers providing SSGT or the active control activity and (iii) school leaders facilitating the implementation of these actions. Due to the impact of the COVID-19 pandemic, comparison between real life versus digital administration of SSGT was also examined. Within a randomized controlled pilot trial of the school-tailored SSGT SKOLKONTAKT^®, the primary perspectives of 20 students, teachers and school leaders on SSGT or the social control activities were explored. All groups perceived SSGT to enhance school attendance and academic achievement of students, as well as teacher inclusion skills and the social school climate. Findings indicate that SSGT is largely feasible and socially valid, and broader implementation of SSGT in school settings appears meaningful.

Assessing Causal Pathways and Targets of Implementation Variability for EBP use (Project ACTIVE): a study protocol

Background

Advancing causal implementation theory is critical for designing tailored implementation strategies that target specific mechanisms associated with evidence-based practice (EBP) use. This study will test the generalizability of a conceptual model that integrates organizational constructs and behavioral theory to predict clinician use of cognitive-behavioral therapy (CBT) techniques in community mental health centers. CBT is a leading psychosocial EBP for psychiatric disorders that remains underused despite substantial efforts to increase its implementation.

Methods

We will leverage ongoing CBT implementation efforts in two large public health systems (Philadelphia and Texas) to recruit 300 mental health clinicians and 600 of their clients across 40 organizations. Our primary implementation outcomes of interest are clinician intentions to use CBT and direct observation of clinician use of CBT. As CBT comprises discrete components that vary in complexity and acceptability, we will measure clinician use of six discrete components of CBT. After finishing their CBT training, participating clinicians will complete measures of organizational and behavior change constructs delineated in the model. Clinicians also will be observed twice via audio recording delivering CBT with a client. Within 48 h of each observation, theorized moderators of the intention-behavior gap will be collected via survey. A subset of clinicians who report high intentions to use CBT but demonstrate low use will be purposively recruited to complete semi-structured interviews assessing reasons for the intention-behavior gap. Multilevel path analysis will test the extent to which intentions and determinants of intention predict the use of each discrete CBT component. We also will test the extent to which theorized determinants of intention that include psychological, organizational, and contextual factors explain variation in intention and moderate the association between intentions and CBT use.

Discussion

Project ACTIVE will advance implementation theory, currently in its infancy, by testing the generalizability of a promising causal model of implementation. These results will inform the development of implementation strategies targeting modifiable factors that explain substantial variance in intention and implementation that can be applied broadly across EBPs.

Preference, Knowledge, and Attitudes of Parents Toward Cognitive Behavioral Therapy for Their Children in Riyadh, Saudi Arabia

Introduction: Cognitive behavioral therapy (CBT) for children and adolescents has shown efficacy in treating different psychiatric disorders. It has been added to multiple clinical guidelines as the first-line treatment. However, despite more studies of its efficacy, CBT is underutilized in clinical settings due to a lack of rigorous training programs and qualified CBT therapists. The limited knowledge of parents in this intervention and their negative attitudes toward it have been considered as possible reasons. Methods: This is a cross-sectional survey-based study among 464 Saudi parents living in Riyadh city. We aimed to evaluate the preference, knowledge, and attitudes of Saudi parents toward CBT for their children. We compared the difference in the level of knowledge and attitudes toward CBT in relation to the characteristics of parents. An online questionnaire that included 39 questions was carefully reconstructed from four validated scales, approved by an expert panel, and piloted. Participants were recruited to participate through online social media. Results: Saudi parents had average knowledge about CBT; however, they had positive attitudes toward the therapy itself and its role in treating the behavioral issues of children. Male participants showed better knowledge than female participants. Participants with higher education and those with high income had more favorable attitudes toward CBT than others. Conclusion: The knowledge of parents is considered inadequate and indicated the need for more awareness and perhaps mass education. In contrast, they maintained positive attitudes and were interested in evidence-based treatment, with more preference toward non-psychopharmacological interventions.

Preliminary evaluation of a culturally adapted CBT-based online programme for depression and anxiety from a lower middle-income country

Online cognitive behaviour therapy (CBT), self-help and guided self-help (GSH) interventions have been found to be efficacious and cost-effective for treatment of anxiety and depression, but there are limited data from low- and middle-income countries on culturally adapted digital interventions for these common mental disorders. The aim of this study was to investigate the feasibility and acceptability of an online culturally adapted CBT-based guided self-help (CaCBT-GSH) for patients with anxiety and depression in Pakistan. This randomized controlled trial recruited 39 participants from primary care in Karachi, Pakistan and randomized them to two groups. The intervention group received seven modules of CaCBT-GSH plus treatment as usual (TAU) over 12 weeks. The control group was a waitlist control plus TAU. The primary outcomes were feasibility and acceptability. Clinical outcomes included results from the Hospital Anxiety and Depression Scale (HADS) and the WHO Disability Assessment Schedule 2 (WHODAS 2). Assessments were carried out at baseline and at 12 weeks. All 39 individuals who met eligibility criteria for the study agreed to participate. Adherence to the intervention was excellent, with 85% (17/20) completing more than five modules. Statistically significant improvements were found in all clinical outcomes in the intervention group. This was the first trial of an online CaCBT-GSH intervention, which was found to be feasible and acceptable to Pakistani patients with anxiety and depression. CaCBT-GSH may help improve symptoms, depression, anxiety and overall functioning in this population. The results provide rationale for a larger, confirmatory randomized controlled trial of digital CaCBT-GSH.

Return on investment of internet delivered exposure therapy for irritable bowel syndrome: a randomized controlled trial

Background

Irritable bowel syndrome (IBS) is a debilitating and costly disorder. Cognitive behavior therapy (CBT) is effective in the treatment of IBS, both when delivered over the internet and in face-to-face settings. CBT consists of different components and little is known about their relative importance. We have in an earlier study showed that inclusion of exposure in the CBT for IBS makes it even more effective. In the present study we wanted to evaluate the economic effects for society of inclusion vs exclusion of exposure in an internet delivered CBT for IBS.

Methods

We used data from a previous study with 309 participants with IBS. Participants were randomized to internet delivered CBT with (ICBT) or without exposure (ICBT-WE). We compared direct and indirect costs at baseline, after treatment, and 6 months after treatment (primary endpoint; 6MFU). Data was also collected on symptom severity and time spent by therapists and participants. The relative Incremental Cost Effectiveness Ratio (ICER) was calculated for the two treatment conditions and the return on investment (ROI).

Results

Results showed that ICBT cost $213.5 (20%) more than ICBT-WE per participant. However, ICBT was associated with larger reductions regarding both costs and symptoms than ICBT-WE at 6MFU. The ICER was − 301.69, meaning that for every point improvement on the Gastrointestinal Symptom Rating Scale—IBS version in ICBT, societal costs would be reduced with approximately $300. At a willingness to pay for a case of clinically significant improvement in IBS symptoms of $0, there was an 84% probability of cost-effectiveness. ROI analysis showed that for every $1 invested in ICBT rather than ICBT-WE, the return would be $5.64 six months after treatment. Analyses of post-treatment data showed a similar pattern although cost-savings were smaller.

Conclusions

Including exposure in Cognitive Behavior Treatment for IBS is more cost-effective from a societal perspective than not including it, even though it may demand more therapist and patient time in the short term.

The effectiveness of cognitive behaviour therapy for reducing anxiety symptoms following traumatic brain injury: A meta-analysis and systematic review

BACKGROUND

Anxiety is a common neuropsychological sequela following traumatic brain injury (TBI). Cognitive Behaviour Therapy (CBT) is a recommended, first-line intervention for anxiety disorders in the non-TBI clinical population, however its effectiveness after TBI remains unclear and findings are inconsistent.

OBJECTIVE

There are no current meta-analyses exploring the efficacy of CBT as an intervention for anxiety symptoms following TBI, using controlled trials. The aim of the current study, therefore, was to systematically review and synthesize the evidence from controlled trials for the effectiveness of CBT for anxiety, specifically within the TBI population.

METHOD

Three electronic databases (Web of Science, PubMed and PsycInfo) were searched and a systematic review of intervention studies utilising CBT and anxiety related outcome measures in a TBI population was performed through searching three electronic databases. Studies were further evaluated for quality of evidence based on Reichow's (2011) quality appraisal tool. Baseline and outcome data were extracted from the 10 controlled trials that met the inclusion criteria, and effect sizes were calculated.

RESULTS

A random effects meta-analysis identified a small overall effect size (Cohen's d) of d = -0.26 (95%CI -0.41 to -0.11) of CBT interventions reducing anxiety symptoms following TBI.

CONCLUSIONS

This meta-analysis tentatively supports the view that CBT interventions may be effective in reducing anxiety symptoms in some patients following TBI, however the effect sizes are smaller than those reported for non-TBI clinical populations. Clinical implications and limitations of the current meta-analysis are discussed.

Sahaj Samadhi meditation vs a Health Enhancement Program in improving late-life depression severity and executive function: study protocol for a two-site, randomized controlled trial

Background

Recent estimates suggest an 11% prevalence of current late-life depression (LLD) and a lifetime prevalence of 16–20%. LLD leads to cognitive disturbance as well as a nearly two to three times increased risk of dementia. We conducted a recent randomized controlled trial (RCT) which demonstrated that Sahaj Samadhi meditation (SSM), an easy-to-implement, meditation-based augmentation strategy, led to higher rates of symptom remission when compared to treatment as usual (40.0 vs 16.3%; odds ratio, 3.36; 95% CI 1.06–10.64; p = 0.040). Here we present a protocol describing a two-site, blinded, RCT, comparing an SSM arm to an active-control arm – a Health Enhancement Program (HEP) intervention – in their ability to reduce depressive symptoms and improve executive functioning, among several other exploratory outcomes.

Methods/design

One hundred and ninety-two (n = 192) participants with LLD will be recruited at two sites (London, ON, Canada, and Montreal, QC, Canada). Participants will undergo stratified randomization with regards to site and the presence of treatment-resistant-LLD (TR-LLD) or not, to either SSM or HEP. We will assess change in (1) depression severity using the Hamilton Depression Rating Scale (HAM-D), (2) executive functioning, and (3) other exploratory physiological and mood-based measures, at baseline (0 weeks), post intervention (12 weeks), and 26 weeks after baseline. Raters, clinicians, and care providers will be blinded to group allocation while participants will be blinded to the study hypotheses.

Discussion

This study should more definitively assess whether SSM can be used as an augmentation strategy in routine clinical care for patients suffering from LLD and TR-LLD. If the effects of SSM are significantly better than HEP, it will offer support for the routine use of this intervention to manage LLD/TR-LLD and comorbid declines in executive dysfunction. The results of this study could also inform whether SSM can improve/prevent cognitive decline in LLD.

Integrated Psychological Care is Needed, Welcomed and Effective in Ambulatory Inflammatory Bowel Disease Management: Evaluation of a New Initiative

BACKGROUND AND AIMS

Inflammatory bowel disease is associated with psychosocial issues which reduce quality of life and impair medical management. However, these issues are rarely addressed in routine care. A model of integrated psychological screening and intervention was trialled to measure prevalence, patient participation, and potential benefits to mental health and/or quality of life.

METHODS

During a 12-month period, 490 adult patients at an established hospital-based service were approached to complete screening instruments for anxiety, depression, general distress, quality of life and medication adherence. Disease-specific and demographic data were also collected. Patients who scored highly on screening questionnaires were offered psychological intervention (in-service or externally referred). Participants were reassessed after 12 months.

RESULTS

Psychological screening was well accepted with 68% (N = 335) participating. Psychological care was 'needed', with 55% (N = 183) scoring highly for anxiety, depression and/or general distress. Half of those 'in need' (N = 91) accepted intervention. In those who accepted, levels of anxiety (mean at intake [M1] = 12.11 vs mean at follow-up [M2] = 9.59, p < 0.001), depression (M1 = 8.38 vs M2 = 6.42, p < 0.001), general distress (M1 = 17.99 vs M2 = 13.96, p < 0.001), mental health quality of life (M1 = 54.64 vs M2 = 59.70, p < 0.001) and overall quality of life (M1 = 57.60 vs M2 = 64.10, p < 0.001) each improved between intake and follow-up. Engagement in psychological intervention was six times greater for those treated in-service vs externally referred (χ2[1] = 13.06, p < 0.001, odds ratio = 6.47).

CONCLUSIONS

Mental health issues are highly prevalent in people with inflammatory bowel disease. Patients are open to psychological screening and treatment. Psychological care can improve patient mental health and quality of life, and works best when integrated into routine management.

Understanding the behavioural determinants of opioid prescribing among family physicians: a qualitative study

BACKGROUND

Longstanding variation in the views of family physicians (FPs) on the role of opioids seems to translate into widely varying prescribing rates. Improvement interventions are unlikely to achieve change if they do not understand and explicitly target the factors that determine physician prescribing behaviour. The aim of this work was to understand (1) the perspectives of FPs as it relates to opioid prescribing, and (2) the perceived barriers and enablers to guideline-adherent opioid prescribing and management of chronic non-cancer pain.

METHODS

A qualitative study involving one-on-one, semi-structured interviews with a sample of FPs in Ontario, Canada. Interviews were analyzed using a directed content analysis informed by the Theoretical Domains Framework. A framework approach was used to explore interaction across behavioural determinants (factors influencing behaviour) as well as demographic sources of variation. The behaviour of interest for the current study was the prescribing of opioid medications (including initiation, renewal, and dose reduction) for patients with chronic, non-cancer pain. Associated issues in the overall management of such patients were also explored.

RESULTS

Interviews were conducted with 22 FPs. Behavioural determinants interacted with one another to influence FPs prescribing behavior. The TDF domain Beliefs about Consequences played a central role in explaining physician prescribing behaviours as they related to the management of chronic non-cancer pain. Individual beliefs about prescribing consequences and patient behaviour interacted with prescriber beliefs about capabilities and perceptions of the FP's professional role to influence prescriber behaviour. Emotion and the environmental context influenced the impact of these determinants on opioid prescribing and the management of chronic non-cancer pain.

CONCLUSIONS

FPs face a wide range of complex (and often interacting) challenges when prescribing opioid therapy to their patients. Solution-based strategies should target these determinants directly using evidence-based strategies that move beyond guideline dissemination and general education. Shared decision-making strategies and patient-facing decision aids are likely to decrease the tension experienced in challenging conversations.

Mobile and traditional cognitive behavioral therapy programs for generalized anxiety disorder: A cost-effectiveness analysis

Background

Generalized anxiety disorder (GAD) is a debilitating mental health illness that affects approximately 3.1% of U.S. adults and can be treated with cognitive behavioral therapy (CBT). With the emergence of digital health technologies, mobile CBT may be a cost-effective way to deliver care. We developed an analysis framework to quantify the cost-effectiveness of internet-based CBT for individuals with GAD. As a case study, we examined the potential value of a new mobile-delivered CBT program for GAD.

Methods

We developed a Markov model of GAD health states combined with a detailed economic analysis for a cohort of adults with GAD in the U.S. In our case study, we used pilot program efficacy data to evaluate a mobile CBT program as either prevention or treatment only and compared the strategies to traditional CBT and no CBT. Traditional CBT efficacy was estimated from clinical trial results. We calculated discounted incremental costs and quality-adjusted life-years (QALYs) over the cohort lifetime.

Case study results

In the base case, for a cohort of 100,000 persons with GAD, we found that mobile CBT is cost-saving. It leads to a gain of 34,108 QALYs and 81,492 QALYs and a cost reduction of $2.23 billion and $4.54 billion when compared to traditional CBT and no CBT respectively. Results were insensitive to most model inputs and mobile CBT remained cost-saving in almost all scenarios.

Limitations

The case study was conducted for illustrative purposes and used mobile CBT efficacy data from a small pilot program; the analysis should be re-conducted once robust efficacy data is available. The model was limited in its ability to measure the effectiveness of CBT in combination with pharmacotherapy.

Conclusions

Mobile CBT may lead to improved health outcomes at lower costs than traditional CBT or no intervention and may be effective as either prevention or treatment.

Understanding clinician attitudes towards implementation of guided self-help cognitive behaviour therapy for those who hear distressing voices: using factor analysis to test normalisation process theory

BACKGROUND

The Normalisation Process Theory (NPT) has been used to understand the implementation of physical health care interventions. The current study aims to apply the NPT model to a secondary mental health context, and test the model using exploratory factor analysis. This study will consider the implementation of a brief cognitive behaviour therapy for psychosis (CBTp) intervention.

METHODS

Mental health clinicians were asked to complete a NPT-based questionnaire on the implementation of a brief CBTp intervention. All clinicians had experience of either working with the target client group or were able to deliver psychological therapies. In total, 201 clinicians completed the questionnaire.

RESULTS

The results of the exploratory factor analysis found partial support for the NPT model, as three of the NPT factors were extracted: (1) coherence, (2) cognitive participation, and (3) reflexive monitoring. We did not find support for the fourth NPT factor (collective action). All scales showed strong internal consistency. Secondary analysis of these factors showed clinicians to generally support the implementation of the brief CBTp intervention.

CONCLUSIONS

This study provides strong evidence for the validity of the three NPT factors extracted. Further research is needed to determine whether participants' level of seniority moderates factor extraction, whether this factor structure can be generalised to other healthcare settings, and whether pre-implementation attitudes predict actual implementation outcomes.

Barriers to disseminating brief CBT for voices from a lived experience and clinician perspective

Access to psychological therapies continues to be poor for people experiencing psychosis. To address this problem, researchers are developing brief interventions that address the specific symptoms associated with psychosis, i.e., hearing voices. As part of the development work for a brief Cognitive Behaviour Therapy (CBT) intervention for voices we collected qualitative data from people who hear voices (study 1) and clinicians (study 2) on the potential barriers and facilitators to implementation and engagement. Thematic analysis of the responses from both groups revealed a number of anticipated barriers to implementation and engagement. Both groups believed the presenting problem (voices and psychosis symptoms) may impede engagement. Furthermore clinicians identified a lack of resources to be a barrier to implementation. The only facilitator to engagement was reported by people who hear voices who believed a compassionate, experienced and trustworthy therapist would promote engagement. The results are discussed in relation to how these barriers could be addressed in the context of a brief intervention using CBT techniques.

Mental Health Service Provision in Low- and Middle-Income Countries

This article discusses the provision of mental health services in low- and middle-income countries (LMICs) with a view to understanding the cultural dynamics-how the challenges they pose can be addressed and the opportunities harnessed in specific cultural contexts. The article highlights the need for prioritisation of mental health services by incorporating local population and cultural needs. This can be achieved only through political will and strengthened legislation, improved resource allocation and strategic organisation, integrated packages of care underpinned by professional communication and training, and involvement of patients, informal carers, and the wider community in a therapeutic capacity.

Efficacy of transdiagnostic cognitive-behavioral group therapy for anxiety disorders and headache in adolescents

Anxiety disorders and headache are both among the most prevalent disorders among adolescents. Although cognitive behavioral therapy (CBT) has proved its efficacy with each of these disorders individually, there are several barriers to its utilization, including cost, gaps in knowledge about treatment delivery and modes, and its utility with comorbid disorders. The current study examined the comparative efficacy of a 12 week TCBT Group treatment (n=32) versus treatment as usual group (n=31) (TAU) in adolescents with anxiety disorders and headache in a north Indian hospital based setting. Results from 63 adolescents suggested while both conditions improved significantly on the Headache Impact Test and Children's Global Assessment Scale, those receiving TCBT showed significantly greater improvement than those in the TAU condition. Participants receiving TCBT, but not those in the TAU condition, showed significant improvement on the State Trait Anxiety Inventory. The study provides evidence supporting the efficacy of TCBT in adolescents with anxiety disorders and headache. Further, group TCBT has the benefits of easy dissemination and increased access to evidence-based treatment, thus, lowering costs and therapist time.

Effect of Psychotherapy on Health Care Utilization in Children With Inflammatory Bowel Disease and Depression

OBJECTIVES

Pediatric patients with inflammatory bowel disease (IBD) are at an increased risk of developing depression compared with community controls. Depression often negatively influences illness behaviors such as resource utilization. We sought to investigate the effects of treating depression on utilization of medical resources in depressed pediatric patients with IBD by comparing rates of health care utilization 1 year before and after psychotherapy.

METHOD

Two hundred seventeen subjects ages 9 to 17 years with IBD and depression received 3 months of psychotherapy for depression as part of a multicenter randomized controlled trial. Of these 217 subjects, 70 had utilization data available 1 year prior and 1 year after receiving 3 months of psychotherapy. Primary outcomes included frequency of hospitalizations, inpatient hospital days, outpatient gastrointestinal visits, and number of emergency room visits, radiological examinations, and endoscopies. Within subject analyses were completed comparing health care utilization 12 months before psychotherapy compared with the 12 months after the conclusion of psychotherapy.

RESULTS

Fifty-one and 19 patients had CD and UC, respectively. A total of 55.7% of patients had major depression and 44.3% had minor depression. Overall, all study measures of health care utilization were significantly reduced after psychotherapy (P < 0.01)-including gastrointestinal-related (mean values) hospitalization frequency, inpatient days, outpatient visit, emergency room visits, radiological examinations, and endoscopies.

CONCLUSIONS

Psychotherapy for comorbid depression in pediatric patients with IBD is associated with decreased GI-related health care utilization. The present study highlights the importance of screening for depression in a pediatric population with IBD, and that psychotherapy may be a reasonable adjunctive treatment for pediatric patients with IBD and comorbid depression.

The Effect of Borderline Personality Pathology on Outcome of Cognitive Behavior Therapy

Cognitive behavioral therapy (CBT) is an evidence-based psychotherapeutic approach which has been shown to be an effective intervention for most psychiatric disorders. There are conflicting data in the literature regarding whether a comorbid personality disorder worsens the prognosis of CBT for depression, anxiety, and other complaints. This study examined data collected before and after courses of CBT for patients with significant borderline (n=39, 11.5%) or obsessive-compulsive (n=66, 19.4%) personality pathology or no personality disorder (n=235, 69.1%). A diagnosis of personality pathology was not a significant predictor of outcome in CBT as measured by the reliable change index. However, patients with borderline personality pathology did demonstrate a greater response to CBT than other patients in terms of improvement on several measures of symptoms. Patients with borderline personality pathology appear to enter therapy with greater subjective depression and interpersonal difficulty than other patients but achieve larger gains during therapy. Implications and directions for future research are discussed.

Personality and coping in first episode psychosis linked to mental health care use

A body of literature focuses on associations of neuroticism, extraversion, passive coping and active coping with the course of psychotic illness. Less is known about other personality and coping variables - and underlying causal mechanisms between variables remain unclear. We explored causal effects from personality, coping and symptoms on mental health care consumption over two years in 208 first episode patients. Causal inference search algorithms lead to formation of a hypothetical causal model based on presumptions on (non-)mutuality between variables and consistent with data. Structural equation modelling estimated effect sizes conditionally on the causal model. Our observed model implies that none of the coping or personality variables have any effect on the number of days of hospitalisation, whereas general psychopathology symptoms do have a direct positive effect. For ambulatory care it is proposed that openness to experience, depressive symptoms and age have direct positive effects. Reassuring thoughts as a coping strategy seems to have a direct negative effect on the use of ambulatory care and mediates indirect effects of other personality and coping variables on ambulatory care. Furthermore, while previously established relations between personality and symptoms are confirmed by our model, it challenges traditional ideas about causation between personality and symptoms.

We need psychologists!

Paediatricians are more likely than ever to encounter patients with mental health problems on a daily basis. There is a need for investment in proven treatments, such as psychology-based interventions, for children identified with mental health disorders. There are four main arguments supporting the engagement of psychologists for children with mental health problems: there is clear evidence that psychological interventions can effectively treat a wide range of mental health disorders; many parents and children are more open to exploring psychological therapies rather than medication for mental health problems; psychologists are trained and licensed to perform psychoeducational assessments, which can provide invaluable information about a child's learning profile, attention problems and overall intelligence; and behaviour problems in children can be prevented or improved through parent-based interventions. The authors' strongly advocate for the public funding of psychology services - both in collaborative primary care models and in the school setting.

Impact of personality psychopathology on outcome in short-term cognitive-behavioral therapy for Axis I disorders

Cognitive behavioral therapy (CBT) is efficacious for many Axis I disorders, though its effectiveness in the real world, for patients with Axis II comorbidity is less well known. This study examines the effectiveness of CBT for Axis I disorders in three groups of patients: those with personality disorders, those with personality disorder traits and those with no Axis II pathology. Consecutive referrals of patients with non-psychotic Axis I disorders were assessed for short-term CBT in a University Teaching Unit. While the acceptance rate was lower for individuals with personality disorders, there were no group differences in dropout rates. Of those who completed therapy (mean number of sessions=17.8, SD=11.2), those in the Personality Disorders group (n=45) had 4 sessions more on average than the Personality Disorder Traits group (n=42) or the No Axis II Group (n=266). All 3 groups were equally successful, whether the outcome was therapist opinion of success, the clinical global impression, or the reliable change index based on patient-reported symptom change. Intent to treat analysis results paralleled those of the completer analysis. Our findings indicate that the presence of a personality disorder does not negatively impact therapy adherence or success in short-term CBT for an Axis I disorder.

U-CARE: Internet-based stepped care with interactive support and cognitive behavioral therapy for reduction of anxiety and depressive symptoms in cancer--a clinical trial protocol

Background

Approximately 20–30% of patients with cancer experience a clinically relevant level of emotional distress in response to disease and treatment. This in itself is alarming but it is even more problematic because it is often difficult for physicians and nurses to identify cancer patients who experience clinically relevant levels of anxiety and depression symptoms. This can result in persistent distress and can cause human suffering as well as costs for individuals and to the community.

Methods

Applying a multi-disciplinary and design-oriented approach aimed at attaining new evidence-based knowledge in basic and applied psychosocial oncology, this protocol will evaluate an intervention to be implemented in clinical practice to reduce cancer patient anxiety and depression. A prospective randomized design will be used.

The overarching goal of the intervention is to promote psychosocial health among patients suffering from cancer by means of self-help programmes delivered via an Internet platform. Another goal is to reduce costs for individuals and society, caused by emotional distress in response to cancer.

Following screening to detect levels of patient distress, patients will be randomized to standard care or a stepped care intervention. For patients randomized to the intervention, step 1 will consist of self-help material, a chat forum where participants will be able to communicate with each other, and a Frequently Asked Questions (FAQ) section where they can ask questions and get answers from an expert. Patients in the intervention group who still report symptoms of anxiety or depression after access to step 1 will be offered step 2, which will consist of cognitive behavioral therapy (CBT) administered by a personal therapist. The primary end point of the study is patients’ levels of anxiety and depression, evaluated longitudinally during and after the intervention.

Discussion

There is a lack of controlled studies of the psychological and behavioral processes involved in this type of intervention for anxiety and depressive disorders. Since anxiety and depressive symptoms are relatively common in patients with cancer and the availability of adequate support efforts is limited, there is a need to develop evidence-based stepped care for patients with cancer, to be delivered via the Internet.

Assessing suitability for short-term cognitive-behavioral therapy in psychiatric outpatients with psychosis: a comparison with depressed and anxious outpatients

OBJECTIVE

The Suitability for Short-Term Cognitive Therapy (SSCT) rating procedure has predicted outcome in depressed and anxious patients. This study examines its relevance in assessing patients with psychosis.

METHOD

Outpatients with psychosis (n=56), depression (n=93), and anxiety (n=264) received cognitive- behavioral therapy in a university hospital teaching unit (mean number of sessions=16, SD=11). Demographic, clinical, and suitability variables were assessed as potential predictors of dropout and success as measured by the Reliable Change Index.

RESULTS

Despite lower suitability scores in the psychosis group, dropout and success rates were similar across groups, although the magnitude of symptom reduction was less in the psychosis group. Across diagnoses, dropout was predicted by unemployment and by reluctance to take personal responsibility for change. In the psychosis group only, dropout was predicted by hostility. Success of completed therapy was predicted by higher baseline agoraphobic anxiety and "responsibility for change" scores.

CONCLUSION

Attention to hostility early in therapy may reduce dropout in psychotic patients. Fostering acceptance of responsibility for change may improve both treatment retention and success across diagnoses. Agoraphobic fear is associated with success, possibly reflecting the effectiveness of behavioral interventions in psychosis and anxiety alike.

Systematic review of intervention practices for depression in the workplace

DESIGN

Systematic Review.

OBJECTIVE

To determine which intervention approaches to manage depression in the workplace have been successful and yielded value for employers in developed economies.

DATA SOURCES

We searched MEDLINE, EMBASE, CINAHL, Central, PsycINFO, and Business Source Premier up to June 2010 using search terms in four broad areas: work setting, depression, intervention, and work outcomes.

STUDY SELECTION

Two independent reviewers selected potential articles that met the following criteria: working age individuals with mild or moderate depression; interventions or programs that were workplace-based or could be implemented and/or facilitated by the employer; inclusion of a comparator group in the analysis; outcomes of prevention, management, and recurrences of work disability or sickness absence, and work functioning.

METHODS

Two reviewers independently reviewed each article for quality and extracted data using standardised forms. Following guidelines from the GRADE Working Group, the quality of evidence addressing each outcome was graded as high, moderate, low, or very low on the basis of six criteria: study design, risk of bias, consistency, generalisability, data precision, and economic benefit. Using this information and following Cochrane Collaboration guidelines, the findings for each intervention were summarised and key messages were developed.

RESULTS

We identified ten randomised trials and two non-randomised studies from various countries and jurisdictions that evaluated a wide range of intervention practices. The evidence was graded as "very low" for all outcomes identified. Therefore, no intervention could be recommended.

CONCLUSIONS

To date, there is insufficient quality of evidence to determine which interventions are effective and yield value to manage depression in the workplace.

Effectiveness of cognitive-behavioural therapy plus pharmacotherapy in inpatient treatment of depressive disorders

BACKGROUND

Meta-analyses show benefits for patients from a combination of medication and cognitive-behavioural psychotherapy. However, it is still unclear whether or not additional cognitive-behavioural therapy (CBT) also produces a better treatment outcome in a naturalistic psychiatric setting.

METHODS

Two-hundred six consecutively registered acute psychiatric inpatients with a unipolar depressive disorder were treated with additional CBT. This combined therapy was then compared with psychiatric primary care in an inpatient setting (clinical management). In addition to pharmacological treatment, 105 of the 206 patients also received symptom-focused CBT after hospitalization. Seventeen-item Hamilton Rating Scale for Depression (HAMD, primary outcome criterion), Beck Depression Inventory (BDI), Dysfunctional Attitude Scale, Clinical Global Impression Scale and the Global Assessment of Functioning were performed with all patients.

RESULTS

Patients who were treated with additional CBT revealed a considerably greater reduction of depressive symptoms than in patients who received inpatient primary care only (HAMD: -22.21 versus -19.86, p = 0.027; BDI: 14.99 versus 11.36, p = 0.031). Moreover, remission rates were significantly higher (HAMD: 72% to 51%, p = 0.045; BDI: 58.8% versus 43.1%, p = 0.044) in the combined treatment group than in the primary care only group.

LIMITATION

The naturalistic design and the inconsistent pharmacological treatment are design flaws.

CONCLUSION

The results show that additional cognitive-behavioural treatment of depressive disorders notably improves outcome over standard procedure in acute psychiatric treatment.

KEY PRACTITIONER MESSAGE

There is a need for treatment strategies to accompany medication. In the Sequenced Treatment Alternatives to Relieve Depression trial (STAR*D), only 33% of the patients reached remission criteria after the first antidepressant treatment step and only 50% after the second step. The strict inclusion criteria of randomized controlled trials often render their patient populations unrepresented. For an accurate view of treatment effectiveness, their results need to be complemented with results gained from trials in clinical practice. Additional cognitive-behavioural treatment notably improves treatment outcomes compared with standard treatments in the acute psychiatric treatment of depressive disorders. The results of this study under naturalistic conditions are an important addition to findings from randomized and controlled studies.

The costs of guideline-concordant care and of care according to patients' needs in anxiety and depression

AIM

To describe the direct and indirect costs for people with anxiety and depressive disorders where guidelines are adhered to and patients' perceived needs are fully met.

METHOD

Data were derived from the Netherlands Study of Depression and Anxiety. At baseline, adult patients were interviewed and they completed questionnaires to measure DSM-IV diagnoses, socio-demographic characteristics and perceived need for care. Actual care data were also derived from electronic medical records. Criteria for guideline adherence were based on general practice guidelines, issued by the Dutch College of General Practitioners. Direct and indirect costs were inferred from the Perceived Need for Care Questionnaire administered at baseline, and the Trimbos and iMTA questionnaire on Costs associated with Psychiatric illness administered at 1-year follow-up.

RESULTS

For 568 patients with a current anxiety or depressive disorder a complete dataset on health care use and absenteeism was available. Guideline adherence was significantly associated with increased care use and corresponding costs, while fully met perceived need was unrelated to costs. Socio-demographic characteristics, severity of symptoms and guideline adherence all affected the societal costs of patients with fully met perceived needs compared with patients with perceived unmet needs.

CONCLUSION

It appears that guideline-concordant care for anxiety and depression costs more than non-concordant care, while care that has fulfilled all of a patient's needs seems not to be more expensive than care that has not met all perceived needs. However, randomized controlled trials should first confirm this conclusion.

Effectiveness and cost offset analysis of group CBT for hypochondriasis delivered in a psychiatric setting: an open trial

Hypochondriasis is highly prevalent in medical settings, has detrimental effects for affected individuals, and is associated with high societal costs. Although cognitive behavior therapy (CBT) has been shown to be effective in the treatment of hypochondriasis, it is not widely available because of a lack of properly trained therapists. Therefore, it is essential to evaluate therapy forms that require less therapist time. The authors investigated the effect and economic impact of group CBT delivered in a psychiatric setting among 24 people with hypochondriasis. A within-group design with prolonged baseline was used, and all participants received 10 weeks of group-based treatment. The primary outcome measures were the Health Anxiety Inventory and the Illness Attitude Scales. Results indicate significant improvement on both measures at posttreatment and 6-month follow-up (Cohen's d = 1.03-1.72). Medical and nonmedical costs were substantially lowered. The authors conclude that group-based CBT delivered in a psychiatric setting is an effective and potentially highly cost-effective treatment for hypochondriasis.

The sequenced treatment alternatives to relieve depression (STAR*D) trial: a review

OBJECTIVE

The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial is the largest open-label, pragmatic trial that has been undertaken to examine the treatment of major depressive disorder. At a cost of US$35 million over 6 years, STAR*D sought to test the effectiveness both of pharmacotherapy and of cognitive therapy, and to ascertain whether certain treatments are more optimal after one or more failed trials.

METHOD

Patients (n = 2876) who presented to either a psychiatry or family practice setting seeking treatment for depression were included in the STAR*D analysis. In the 4 levels of STAR*D, patients were randomized to various treatment monotherapies, combinations, or augmentation strategies. The primary outcome was remission, based on the Hamilton Depression Rating Scale. Secondary outcomes were response, as measured by clinician and patient self-report as well as various measures of patients' level of function and (or) quality of life.

RESULTS

Remission rates for treatment levels 1 to 2 and 3 to 4 were 18% to 30% and 7% to 25%, respectively. There was no difference in effectiveness between any treatments at any treatment level. Patients with longer index episodes, more concurrent psychiatric or general medical disorders, and (or) lower measures of baseline function were less likely to achieve remission. There were no major differences between outcomes in patients treated in primary, compared with specialist care, nor were there significant differences between depression rating scores obtained through clinician ratings, compared with self-report.

CONCLUSION

Results of the STAR*D trial have shed important light on the effectiveness of current treatment strategies for patients with depression.

Cognitive behaviour therapy for improving social recovery in psychosis: cost-effectiveness analysis

A randomised trial was conducted in order to estimate the clinical and cost-effectiveness of social recovery orientated cognitive behavioural therapy (SRCBT) for people diagnosed with psychosis, compared to case management alone (CMA). The mean incremental health and social care cost, and the mean incremental quality adjusted life year (QALY) gain, of SRCBT was calculated over the 9 month intervention period. The cost-effectiveness of SCRBT was in turn estimated, and considered in relation to the cost-effectiveness threshold of 20000 UK pounds per QALY. The level of uncertainty associated with that decision was estimated by calculating the cost-effectiveness acceptability curve for SRCBT. N=35 received SRCBT and N=42 received CMA. The mean incremental cost was estimated to be 668 UK pounds, and the mean incremental QALY gain 0.035. SRCBT was estimated to be cost-effective as it had a cost per QALY of 18844 UK pounds, which was more favourable than the assumed cost-effectiveness threshold of 20000 UK pounds per QALY. At that threshold the probability of being cost-effective was however estimated to be 54.3% according to the CEAC, suggesting that further research may be warranted in order to reduce the level of uncertainty associated with the decision as to whether SRCBT is cost-effective.

Preventing panic disorder: cost-effectiveness analysis alongside a pragmatic randomised trial

BACKGROUND

Panic disorder affects many people, is associated with a formidable disease burden, and imposes costs on society. The annual influx of new cases of panic disorder is substantial. From the public health perspective it may therefore be a sound policy to reduce the influx of new cases, to maintain the quality of life in many people, and to avoid the economic costs associated with the full-blown disorder. For this purpose, prevention is needed. Here we present the first economic evaluation of such an intervention.

METHODS

Randomised trial of 117 people with panic disorder symptoms not meeting the diagnostic criteria of DSM-IV panic disorder. The interventions were time-limited cognitive-behavioural therapy v care-as-usual. The central clinical endpoint was DSM-IV panic disorder-free survival over 3 months. Costs were calculated from the societal perspective. Using the bootstrap method, incremental cost-effectiveness ratios were obtained, placed in 95% confidence intervals, projected on the cost-effectiveness plane, and presented as acceptability curves.

RESULTS

The median incremental cost-effectiveness ratio is euro6,198 (95% CI 2,435 - 60,731) per PD-free survival gained, which has a likelihood of 75.2% of being more acceptable from a cost-effectiveness point of view than care-as-usual when a willingness-to-pay ceiling is assumed of euro10,000 per PD-free survival. The most significant cost driver was therapists' time. A sensitivity analysis indicated that cost-effectiveness improves when the number of therapist hours is reduced.

CONCLUSION

This is the first economic evaluation alongside a prevention trial in panic disorder. The small sample (n = 117) and the short time horizon of 3 months preclude firm conclusions, but our findings suggest that the intervention may be acceptable from a cost-effectiveness point of view, especially when therapist involvement can be kept minimal. Nevertheless, our results must await replication in a larger trial with longer follow-up times before we can confidently recommend implementation of the intervention on a broad scale. In the light of our findings and given the burden of panic disorder, such a new trial is well worth the effort.
