Cognitive behavioral therapies for depression and anxiety in people with chronic disease: A systematic review and meta-analysis.

OBJECTIVE: Anxiety and depression in chronic disease are common and burdensome co-morbidities. There has been growing interest in cognitive and behavioral therapies (CBTs) for anxiety and depression in chronic disease, however their efficacy has not been well-established. This study examined the efficacy of CBTs for depression and/or anxiety symptoms within chronic disease and explored the moderating role of clinical and methodological characteristics. METHODS: Following prospective registration, electronic databases were searched up to 2023 for randomized controlled trials (RCTs) examining CBTs for depression and/or anxiety in any adult chronic disease population. RESULTS: We included 56 RCTs. The overall effect of CBTs was g = 0.61 (95% CI, 0.49, 0.72) for depression and g = 0.56 (95% CI, 0.42, 0.70) for anxiety. A range of methodological features significantly moderated the effect sizes obtained, including type of control group and the outcome measure used. Risk of Bias ratings indicated some concerns regarding RCT conduct and reporting. CONCLUSIONS: CBTs lead to moderate improvements in both depression and anxiety symptoms among people with chronic disease. However, the efficacy of CBT should be interpreted considering certain study and sample characteristics. It is recommended that future studies make improvements to study methodology and reporting.

An open trial of the Things You Do Questionnaire: Changes in daily actions during internet-delivered treatment for depressive and anxiety symptoms.

Many psychological treatments aim to reduce symptoms of depression and anxiety by modifying maladaptive patterns of cognitions, behavior, and other actions. The Things You Do Questionnaire (TYDQ) was developed to measure the frequency of actions that are associated with psychological health in a reliable and valid manner. The present study examined treatment-related change in the frequency of actions measured by the TYDQ. Using an uncontrolled single-group design, 409 participants with self-reported symptoms of depression, anxiety, or both received access to an 8-week internet-delivered treatment course based on cognitive behavior therapy. Most (77 %) participants completed the treatment, completed questionnaires at post-treatment (83 %), and obtained significant reductions in symptoms of depression (d = 0.88) and anxiety at post-treatment (d = 0.97), as well as improvement in a measure of satisfaction with life (d = 0.36). Factor analyses supported the five-factor structure of the TYDQ, including Realistic Thinking, Meaningful Activities, Goals and Plans, Healthy Habits, and Social Connections. Those participants who, on average, engaged in the identified actions on the TYDQ at least half the days of the week reported lower symptoms of depression and anxiety at post-treatment. The psychometric properties of both a longer 60-item (TYDQ-60) and shorter 21-item (TYDQ-21) version were acceptable. These findings provide further evidence that there are modifiable activities that are strongly associated with psychological health. Future studies will test the replicability to these results in in a broader range of samples, including those seeking psychological treatment.

The Chronic Conditions Course: A Randomised Controlled Trial of an Internet-Delivered Transdiagnostic Psychological Intervention for People with Chronic Health Conditions.

INTRODUCTION: Psychological adjustment to chronic health conditions is important, as poor adjustment predicts a range of adverse medical and psychosocial outcomes. Psychological treatments demonstrate efficacy for people with chronic health conditions, but existing research takes a disorder-specific approach and they are predominately delivered in face-to-face contexts. The internet and remotely delivered treatments have the potential to overcome barriers to accessing traditional face-to-face treatment. OBJECTIVE: The current study examined the efficacy and acceptability of an internet-delivered transdiagnostic psychological intervention to promote adjustment to illness, based on cognitive behaviour therapy principles. METHODS: In a two-arm randomised controlled trial, participants (n = 676) were randomly allocated to the 8-week intervention or a waitlist control. Treatment included five core lessons, homework tasks, additional resources, and weekly contact with a psychologist. Primary outcomes included depression, anxiety, and disability, assessed at pre-treatment, post-treatment, 3-month follow-up, and 12-month follow-up. RESULTS: The treatment group reported significantly greater improvements in depression (between-groups d = 0.47), anxiety (d = 0.32), and disability (d = 0.17) at post-treatment (all ps <0.001). Improvements were sustained over the 3-month and 12-month follow-ups. High treatment completion rates (69%) and levels of satisfaction (86%) were reported by participants in treatment. The intervention required a mean clinician time of 56.70 min per participant. CONCLUSIONS: The findings provide preliminary and tentative support for the potential of internet-delivered transdiagnostic interventions to promote adjustment to chronic health conditions. Further research using robust control groups, and exploring the generalisability of findings, is needed before firm conclusions can be drawn.

The Pain Course: a randomised controlled trial and economic evaluation of an internet-delivered pain management program.

ABSTRACT: There is interest in the potential of Internet-delivered programs to cost-effectively increase access to pain management for people with chronic pain. However, few large-scale clinical and economic evaluations have been undertaken. Using a randomised controlled trial design, the current study (n = 659) examined the clinical efficacy, cost-effectiveness, and cost utility of an Internet-delivered pain management program for people with mixed chronic pain conditions when delivered with optional clinician support. The treatment group reported significant improvements in disability, depression, anxiety, average pain intensity, and quality-adjusted life years (QALYs), compared with control, and exhibited relatively high levels of treatment engagement and satisfaction. Each additional clinical improvement (defined as ≥ 30% improvement) produced by the intervention, over control, was associated with a cost of $48, $27, $38, and $83 for disability, depression, anxiety, and average pain intensity, respectively. Gaining one QALY was associated with a cost of $152 or $11,910 per QALY when an 80% probability criterion for cost utility was applied. The program itself was associated a relatively small, fixed, cost per patient but was not cost saving over the brief intervention period. The findings support the clinical efficacy and cost-effectiveness of Internet-delivered programs with "on demand" clinician support as a way to increase access to pain management. Key limitations of the current study include the use of a waitlist-control group, a short follow-up period, and the focus on governmental healthcare costs. Further evaluation of these programs is necessary if they are scaled up and offered as routine care.

A Cost-effectiveness Analysis of an Internet-delivered Pain Management Program Delivered With Different Levels of Clinician Support: Results From a Randomised Controlled Trial.

There is growing interest in the potential of internet-delivered pain management programs (PMPs) to increase access to care for people with chronic pain. However, very few economic evaluations of these interventions have been reported. Using existing data, the current study examined the cost-effectiveness of an internet-delivered PMP for a mixed group chronic pain patients (n = 490) provided with different levels of clinician support. The findings indicated that each additional clinical outcome (defined as a ≥ 30% reduction in disability, depression, anxiety, and pain) was associated with cost-savings when the intervention was provided in a self-guided format (ICER range: -$404--$808 AUD) or an optional-guided format (ICER range: -$314--$541 AUD), and a relatively small fixed cost when provided in the clinician-guided format (ICER range: $88-$225 AUD). The results were driven by a reduction in service use costs among the treatment groups, which offset the costs of providing the internet-delivered PMP in the self-guided and optional-guided formats. The same general pattern of results was found when more stringent clinical outcomes (defined as a ≥ 50% reduction) were employed. These findings suggest that carefully developed and administered internet-delivered PMPs, provided with different levels of clinician support, can be highly cost effective for patients with a broad range of pain conditions. PERSPECTIVE: This study examines the cost-effectiveness of an internet-delivered PMP provided to adults with a broad range of chronic pain conditions. Evidence of cost-effectiveness was found across a broad range of clinical outcomes and with different levels of clinician support.

Examining an internet-delivered intervention for anxiety and depression when delivered as a part of routine care for university students: A phase IV trial.

BACKGROUND: There has been growing interest in the potential of emerging internet-delivered psychological treatments for supporting the mental health needs of university students. However, no large-scale prospective effectiveness trials examining their real-world potential have been reported. OBJECTIVE: The aim of the current study was to evaluate the acceptability and effectiveness of a brief, 5-week, internet-delivered and therapist-guided intervention for anxiety and depression, when delivered as part of routine care by a university counselling service. DESIGN: A large, prospective, single-group Phase-IV clinical trial. Students (n = 1326) engaging with the university counselling service were provided the opportunity to receive the intervention based on their preferences and identified needs. Students completed standardised measures of anxiety and depression at pre-treatment, each week of the intervention, post-treatment and 3-month follow-up. RESULTS: Over a 4 year period, 1081 students (10% of those presenting to the counselling service) participated in the intervention. Large clinical reductions in symptoms of both anxiety (% reduction = 41%; Cohen's d = 0.94) and depression (% reduction = 36%; Cohen's d = 0.81) were observed alongside high levels of acceptability. The intervention required relatively little counsellor time (M = 36.28 mins; SD = 20.56) per student, and symptom deterioration was observed in less than 5% of students. CONCLUSION: The findings of the current study are supportive of internet-delivered interventions provided as routine care to university students. Further research is needed to carefully explore whether these interventions could be used with a larger proportion of students presenting to counselling services, paying close attention to acceptability, engagement and clinical outcomes.

Internet-delivered treatment for young adults with anxiety and depression: Evaluation in routine clinical care and comparison with research trial outcomes.

INTRODUCTION: Mood and anxiety disorders typically emerge in adolescence and early adult life, but young adults are often reluctant to seek treatment. The Mood Mechanic course is a transdiagnostic internet-delivered psychological intervention for symptoms of depression and anxiety, targeted at people aged 18-24 years. The current study compared the efficacy of the course when delivered under strict research trial conditions (research trial; n = 192) with its effectiveness in a routine health-care setting (routine care; n = 222). METHODS: Symptoms of depression, anxiety and general distress at baseline, during, and after treatment were measured by the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), and Kessler 10-Item Scale (K-10), respectively. RESULTS: Both groups showed significant symptom reductions on all measures at post-treatment and 3-month follow-up. Deterioration rates were low, within-group effect sizes were large (>1.0) and both groups reported high levels of treatment satisfaction. Patients in routine care were less likely to complete post-treatment or follow-up symptom questionnaires. LIMITATIONS: The study is based on self-reported data from treatment-seeking individuals that were motivated enough to start the course, and the absence of a control group and a formal diagnosis in the routine care sample means that some caution is needed in generalising the results. CONCLUSION: The results show that the Mood Mechanic course is effective and acceptable in routine clinical care, and that online psychological interventions designed for young adults are an effective treatment option for this hard-to-reach group.

Involvement in compensation litigation and outcome from an online pain management program.

OBJECTIVE: To report on the effect of involvement in civil litigation on outcome for patients enrolled in a validated Internet-delivered pain management program, the Pain Course. RESEARCH METHOD: Data from a randomized controlled trial (RCT) on the effect of varying levels of clinician support was used to examine the effect of involvement in civil litigation on outcome in a free online pain management course. Outcome measures were changes in scores on self-report questionnaires for depression, anxiety, and disability (PHQ-9, GAD-7, and RMDQ) from baseline to 3-month follow-up for those still involved in litigation and those who had completed litigation, compared with outcomes for those who did not report involvement in litigation. The use of regular and as-required opioid medication at assessment and follow-up were also compared. RESULTS: Of the 397 patients enrolled in the pain course, 290 (73.0%) were not involved in litigation, 80 (20.2%) reported involvement in litigation that had been resolved and 27 (6.8%) reported ongoing litigation. Those still involved in litigation had the highest scores on depression scales and the highest rate of opioid use. The completion rates and symptom improvement was lower among current litigants but were still positive, with effect sizes on the outcome measures of between 0.56 and 0.73, as well as a reduction in the use of opioids. CONCLUSIONS: Current involvement in compensation litigation was associated with lower treatment completion and less symptom improvement. Nevertheless, the positive findings have significant implications for people involved in workers' compensation and other litigation who report pain as one of their symptoms.

Psychometric properties and clinical utility of brief measures of depression, anxiety, and general distress: The PHQ-2, GAD-2, and K-6.

OBJECTIVE: The nine-item Patient Health Questionnaire (PHQ-9), seven-item Generalized Anxiety Disorder scale (GAD-7), and ten-item Kessler Psychological Distress Scale (K-10) are valid and reliable measures of depression, anxiety and general distress. However, the time required in their administration may limit their use in routine care. This study examines the utility of shorter versions (PHQ-2, GAD-2, and K-6) as screening instruments and measures of treatment response. METHOD: Data from research trial participants (n = 993) receiving internet-delivered cognitive behaviour therapy (iCBT) were analysed to establish discriminant validity of the short versions. Mini International Neuropsychiatric Interview (MINI) diagnoses were used as comparators. Criterion group validity, test-retest reliability, internal consistency, and responsiveness to treatment changes were examined. Analyses were replicated using data from patients receiving iCBT in routine care (n = 1389). RESULTS: Discriminant validity was excellent for the PHQ-2, and acceptable for the GAD-2 and K-6. Acceptable sensitivity and specificity were identified at a threshold of ≥3 for the PHQ-2 and GAD-2, and ≥14 for the K-6. The short versions were sensitive to treatment change. CONCLUSION: The PHQ-2, GAD-2 and K-6 are useful screeners and efficient measures of treatment progress and outcomes in routine clinical care.

The Pain Course: 12- and 24-Month Outcomes From a Randomized Controlled Trial of an Internet-Delivered Pain Management Program Provided With Different Levels of Clinician Support.

Little is known about the long-term outcomes of emerging Internet-delivered pain management programs. The current study reports the 12- and 24-month follow-up data from a randomized controlled trial (n = 490) of an Internet-delivered pain management program, the Pain Course. The initial results of the trial to the 3-month follow-up have been reported elsewhere. There were significant improvements in disability, depression, anxiety, and pain levels across 3 treatment groups receiving different levels of clinician support compared with a treatment as the usual control. No marked or significant differences were found between the treatment groups either after treatment or at the 3-month follow-up. The current study obtained long-term follow-up data from 78% and 79% of participants (n = 397) at the 12-month and 24-month follow-up marks, respectively. Clinically significant decreases (average percent reduction; Cohen's d effect sizes) were maintained at the 12- and 24-month follow-ups for disability (average reduction ≥27%; d ≥ .67), depression (average reduction ≥36%; d ≥ .80), anxiety (average reduction ≥38%; d ≥ .66), and average pain levels (average reduction ≥21%; d ≥ .67). No marked or consistent differences were found among the 3 treatment groups. These findings suggest that the outcomes of Internet-delivered programs may be maintained over the long term. PERSPECTIVE: This article presents the long-term outcome data of an established Internet-delivered pain management program for adults with chronic pain. The clinical improvements observed during the program were found to be maintained at the 12- and 24-month follow-up marks. This finding indicates that these programs can have lasting clinical effects.

Treating anxiety and depression in young adults: A randomised controlled trial comparing clinician-guided versus self-guided Internet-delivered cognitive behavioural therapy.

BACKGROUND: Internet-delivered cognitive behaviour therapy may increase access by young adults to evidence-based treatments for anxiety and depression. OBJECTIVE: The aim of this study was to compare the efficacy of an Internet-delivered cognitive behaviour therapy intervention designed for adults aged 18-24 years, when delivered in clinician-guided versus self-guided formats. DESIGN: The intervention, the Mood Mechanic Course, is a transdiagnostic treatment that simultaneously targets symptoms of anxiety and depression using cognitive and behavioural skills. The brief intervention comprised four lessons, delivered over 5 weeks. Following a brief telephone interview, young adults ( n = 191) with symptoms of anxiety and depression were randomly allocated to either (1) clinician-guided treatment ( n = 96) or (2) self-guided treatment ( n = 95). RESULTS: At post treatment, large reductions (average improvement; clinician guided vs self-guided) were observed in symptoms of anxiety (44% vs 35%) and depression (40% vs 31%) in both groups. Significant improvements were also observed in general psychological distress (33% vs 29%), satisfaction with life (18% vs 15%) and disability (36% vs 29%). No marked or consistent differences in clinical outcomes emerged between conditions at post-treatment, at 3-month or 12-month follow-up. Satisfaction was high with both treatment formats, but slightly higher for clinician-guided treatment. CONCLUSION: These results indicate the potential of carefully developed Internet-delivered cognitive behaviour therapy interventions for young adults with anxiety and depression provided in either self or therapist-guided format. Further large-scale research is required to determine the short- and long-term advantages and disadvantages of different models of support.
