Sudden gains in depression and anxiety during an online pain management programme for chronic pain.

BACKGROUND: Chronic pain is associated with depression and anxiety symptoms. Pain management programms, delivered face-to-face or via the internet, can effectively help adults manage the impacts of chronic pain. Sudden gains are defined as substantial, rapid, and lasting symptom reductions that occur between consecutive treatment sessions and have been associated with better treatment outcomes in non-pain samples. This study examined whether adults with chronic pain report sudden gains in depression or anxiety symptoms during an 8-week online pain management programme, and whether sudden gains were associated with better treatment outcomes for depression or anxiety. Dominant theories of sudden gains argue that therapists are required for sudden gains to be maintained and improve treatment outcomes. METHODS: Using data from a published randomized controlled trial (n = 338), sudden gains and treatment outcomes were compared across three levels of therapist guidance provided alongside the programme: weekly, optional, and self-guided. RESULTS: Similar rates of sudden gains were observed in depression (22%) and anxiety (24%) across the treatment period, and most sudden gains occurred between Weeks 1 and 2 of treatment. Therapist guidance was not associated with sudden gains; higher baseline symptom severity emerged as the only consistent predictor of sudden gain status. No significant differences in treatment outcomes for depression or anxiety symptoms between sudden gainers and non-gainers were observed across therapist guidance conditions. CONCLUSIONS: These results do not support an association between sudden gains in depression or anxiety symptoms and better post-treatment outcomes, at least for adults with chronic pain. SIGNIFICANCE STATEMENT: Sudden gains in depression and anxiety symptoms were not associated with improved treatment outcomes for adults with chronic pain who participated in an online pain management programme, regardless of the level of therapist guidance provided. These findings suggest possible differences in symptom change in chronic pain samples compared to general population samples.

An online therapist-guided ultra-brief treatment for depression and anxiety: a randomized controlled trial.

BACKGROUND: There are many barriers to engaging in current psychological treatments, including time, cost, and availability. Ultra-brief treatments overcome some of these barriers by delivering therapeutic information and skills using significantly less time than standard-length treatments. We developed a therapist-guided online ultra-brief treatment for depression and anxiety and compared it to an existing 8-week, 5-lesson therapist-guided standard-length treatment and a waitlist control. METHODS: In a randomized controlled trial, adults with self-reported depression or anxiety were randomized (1:1:1) to the ultra-brief treatment, standard-length treatment, or waitlist control. The primary outcomes were depression symptoms and anxiety symptoms assessed at baseline, 5-weeks later, 9-weeks later (primary timepoint), and 3-months later. The trial was prospectively registered. RESULTS: Between 7 February 2022, and 16 August 2022, 242 participants were enrolled in the ultra-brief treatment (n = 85), standard-length treatment (n = 80), and waitlist control (n = 77). Participants were mostly women with an average age of 48.56 years. At 9-weeks post-baseline, participants in the ultra-brief treatment group reported significantly lower depression (between groups d = 0.41) and anxiety (d = 0.53) than the waitlist control. The ultra-brief treatment was non-inferior for anxiety at both 9-weeks and 3-months follow-up. Non-inferiority for depression was observed at 9-weeks. CONCLUSIONS: The online ultra-brief treatment resulted in significant reductions in depression and anxiety that were non-inferior to a longer treatment course after 9-weeks. Remotely delivered ultra-brief treatments have the potential to provide accessible and effective care for those who cannot, or would prefer not to, access longer psychological interventions.

Internet-Delivered Psychological Pain-Management for Young Adults With Chronic Pain: An Investigation of Clinical Trial Data.

Young adults report chronic pain at rates of around 12% but lack access to clinical services. There is interest in learning how this emerging adult population engages with and responds to treatment. Using data from young adults aged 18 to 30 years (Mage = 25.8, SD = 3.2), taken from 4 previous randomised controlled trials, the current study investigated the feasibility, acceptability, and efficacy of an internet-delivered psychological pain-management intervention for young adults with chronic pain. We compared young adults in a treatment group (n = 104) with 1) a young-adult wait-list control group (n = 48), and 2) a treatment group reflecting the average-aged participant from the previous trials (39-63 years, n = 561). Feasibility was determined through treatment engagement, adherence and completion, and acceptability through a treatment satisfaction measure. Clinical outcomes were disability, pain intensity, anxiety, and depression; assessed at pre-treatment, post-treatment, and 3-month follow-up. Generalised estimation equation analyses were undertaken, using multiple imputations to account for missing data. Young adults had high engagement and acceptability ratings, though 34% did not complete the intervention. The treatment group significant improved across all outcomes, compared with control, with improvements maintained at follow-up. Post-treatment improvements were equivalent for young-adult and average-aged adult treatment groups, with no significant differences in feasibility or acceptability outcomes. Findings indicate young adults can engage with and show improvements following a psychological pain-management intervention designed for all adults with chronic pain. Future research is encouraged to examine outcomes related to role functioning of young adults, and moderators of treatment acceptability and efficacy for this population. PERSPECTIVE: Secondary analysis of data from 4 RCTs found an Internet-delivered psychological pain-management intervention acceptable and clinically efficacious for improving disability, anxiety, depression and pain intensity in young adults (18-30) with chronic pain.

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.

Prevalence and Predictors of Long COVID in Patients Accessing a National Digital Mental Health Service.

MindSpot is a national mental health service that provides assessments and treatment to Australian adults online or via telephone. Since the start of 2020, questions related to the mental health impacts of COVID-19 have been routinely administered. The objective of the current study is to report the prevalence and predictors of self-reported "long COVID" in patients completing an assessment at the MindSpot Clinic between 5 September 2022 and 7 May 2023 (n = 17,909). Consistent with the World Health Organization definition, we defined long COVID as the occurrence of ongoing physical or mental health symptoms three months after a COVID-19 infection. We conducted a descriptive univariate analysis of patients who reported: no COVID-19 diagnosis (n = 6151); a current or recent (within 3 months) COVID-19 infection (n = 2417); no symptoms three months post-COVID-19 infection (n = 7468); or COVID-related symptoms at least three months post-infection (n = 1873). Multivariate logistic regression was then used to compare patients with and without symptoms three months post-COVID to identify potential predictors for long COVID. The prevalence of long COVID was 10% of the total sample (1873/17909). Patients reporting symptoms associated with long COVID were older, more likely to be female, and more likely to be depressed and report a reduced ability to perform their usual tasks. Sociodemographic factors, including cultural background, education, and employment, were examined. These results provide evidence of the significant prevalence of symptoms of long COVID in people using a national digital mental health service. Reporting outcomes in an Australian context and in specific sub-populations is important for public health planning and for supporting patients.

Depression and Anxiety Trajectories in Chronic Disease: A Systematic Review and Meta-Analysis.

INTRODUCTION: People living with chronic diseases are at an increased risk of anxiety and depression, which are associated with poorer medical and psychosocial outcomes. Many studies have examined the trajectories of depression and anxiety in people with specific diseases, including the predictors of these trajectories. This is valuable for understanding the process of adjustment to diseases and informing treatment planning. However, no review has yet synthesised this information across chronic diseases. METHODS: Electronic databases were searched for studies reporting trajectories of depression or anxiety in chronic disease samples. Data extracted included sample characteristics, results from trajectory analyses, and predictors of trajectories. Meta-analysis of the overall pooled prevalence of depression and anxiety trajectories was conducted, and qualitative synthesis of disease severity predictors was undertaken. RESULTS: Following search and screening, 67 studies were included (N = 61,201 participants). Most participants followed a stable nonclinical trajectory for depression (69.0% [95% CI: 65.6, 72.2]) and anxiety (73.4% [95% CI: 66.3, 79.5]). Smaller but meaningful subsamples followed a trajectory of depression and anxiety symptoms consistently in the clinical range (11.8% [95% CI: 9.2, 14.8] and 13.7% [95% CI: 9.3, 19.7], respectively). Several clinical and methodological moderators emerged, and qualitative synthesis suggested that few aspects of disease severity were associated with participants' trajectories. CONCLUSION: Most people with chronic disease follow a trajectory of distress that is low and stable, suggesting that most people psychologically adjust to living with chronic disease. Evidence also suggests that the nature and severity of the disease are not meaningful predictors of psychological distress.

Evaluation of a therapist-guided virtual psychological pain management program when provided as routine care: a prospective pragmatic cohort study.

INTRODUCTION: Numerous randomized controlled trials have evaluated the outcomes of internet-delivered psychological pain management programs (PMPs) as a way of increasing access to care for people with chronic pain. However, there are few reports of the effectiveness of these PMPs when provided as part of routine care. METHODS: The present study sought to report the clinical and demographic characteristics of users (n = 1367) and examine the effectiveness of an established internet-delivered psychological PMP program in improving several pain-related outcomes, when offered at a national digital mental health service over a 5-year period. It also sought to comprehensively explore predictors of treatment commencement, treatment completion, and clinical improvement. RESULTS: Evidence of clinical improvements (% improvement; Hedges g) were found for all outcomes, including pain interference (18.9%; 0.55), depression (26.1%; 0.50), anxiety (23.9%; 0.39), pain intensity (12.8%; 0.41), pain self-efficacy (-23.8%; -0.46) and pain-catastrophizing (26.3%; 0.56). A small proportion of users enrolled but did not commence treatment (13%), however high levels of treatment completion (whole treatment = 63%; majority of the treatment = 75%) and satisfaction (very satisfied = 45%; satisfied = 37%) were observed among those who commenced treatment. There were a number of demographic and clinical factors associated with commencement, completion and improvement, but no decisive or dominant predictors were observed. DISCUSSION: These findings highlight the effectiveness and acceptability of internet-delivered psychological PMPs in routine care and point to the need to consider how best to integrate these interventions into the pathways of care for people with chronic pain.

An open trial of the feasibility of brief internet-delivered acceptance and aommitment therapy (iACT) for chronic anxiety and depression.

Anxiety and depressive disorders are common, often chronic and result in significant disability and distress. The delivery of psychological interventions via the internet is now recognised to be a safe and effective way to treat these disorders. The predominant therapeutic model in clinical trials and in routine care has been cognitive-behavioural therapy (CBT), which helps patients identify and modify unhelpful thoughts and behaviours. However, other models of treatment for anxiety and depression, such as acceptance and commitment therapy (ACT), which uses the examination of both positive and negative experiences in the service of living a personally meaningful and values-based life, have been developed and tested, although most of these interventions are long and require more clinician support to ensure adherence and achieve positive outcomes. The aim of the present study was to examine the feasibility of a new brief, clinician supported transdiagnostic internet-delivered (iACT) program, designed to treat symptoms of both anxiety and depression and improve social function. A single-group open trial was conducted on 24 adults with long-term symptoms of anxiety and depression. The course is comprised of five online modules delivered over 8 weeks either self-guided or with support from a clinician. There was a high course completion rate (70 %) and a high level of satisfaction with the course (94 % satisfied or very satisfied). Significant clinical improvement in our primary outcome measures (within-group Cohen's d) of anxiety (d ≥ 0.62), depression (d ≥ 0.63), disability (d ≥ 0.43) and quality of life (d ≥ -0.57) were observed at posttreatment. Relatively little clinician time was required per participant (M = 30.6 min, SD = 5.7). The findings of the current study support the feasibility and potential of a transdiagnostic iACT treatment for adults experiencing long-term symptoms of anxiety and depression, including those patients who have not derived benefit from other treatments.

The Timing and Magnitude of Improvements in Depression, Anxiety, Disability, and Pain Intensity During an Internet-delivered Program for Chronic Pain.

Numerous studies have found that pain management programs are an effective treatment option for people with chronic pain. However, little is known about when people experience improvements during these programs and why they are effective. Using a secondary analysis, the current study examined the timing and magnitude of symptom change during an 8-week internet-delivered psychological pain management program for people with chronic pain. The change in 4 outcomes was examined: depression (n = 881), anxiety (n = 561), disability (n = 484), and pain intensity (n = 484). The largest improvements in depression, anxiety, and disability were reported during the first half of treatment (ie, 4 weeks), whereas the largest reductions in pain intensity were reported during the second half of treatment. Half the participants had experienced a clinically meaningful improvement in depression or anxiety, and a third of participants had reported such an improvement in disability by midtreatment (ie, 5 weeks after baseline). In a subgroup analysis (n = 397), this pattern of change in depression and anxiety symptoms did not differ based on the level of therapist guidance. This study highlights the importance of the first few weeks of psychological pain management programs and encourages future work to examine how the mechanisms underpinning rapid change may be harnessed to optimize care for people with chronic pain. PERSPECTIVE: This study found that depression, anxiety, and disability improved rapidly during the first half of an 8-week internet-delivered pain management program, and most of the prepost change had occurred by midtreatment. This work highlights the therapeutic potential of the first few treatment sessions and prompts future research into a rapid responding.

The impact of obesity and overweight on response to internet-delivered cognitive behavioural therapy for adults with chronic health conditions.

BACKGROUND: There is growing evidence that internet-delivered cognitive behavioural therapy (iCBT) can improve functioning and reduce psychological distress in people with chronic health conditions. Obesity frequently co-occurs with chronic health conditions, yet its impact on response to psychological interventions in this population is not known. The current study examined associations between BMI and clinical outcomes (depression, anxiety, disability, and satisfaction with life) following a transdiagnostic iCBT program targeting adjustment to chronic illness. METHODS: Participants from a large randomised controlled trial, who provided information on height and weight, were included (N = 234; mean age= 48.32, SD = 13.80; mean BMI = 30.43, SD = 8.30, range 16.18-67.52; 86.8% female). The influence of baseline BMI range on treatment outcomes at post-treatment and 3-month follow-up was examined using generalized estimating equations. We also examined changes in BMI and in participants' perceived impact of weight on their health. RESULTS: Improvement in all outcomes occurred across BMI ranges; additionally, persons with obesity or overweight generally experienced greater symptom reductions than those within a healthy weight range. A greater proportion of participants with obesity achieved clinically significant change on key outcomes (e.g., depression: 32% [95% CI: 25%, 39%]) than participants with a healthy weight (21% [95% CI: 15%, 26%]) or overweight (24% [95% CI: 18%, 29%], p = 0.016). There were no significant changes in BMI from pre-treatment to 3-month follow-up, however there were significant reductions on the self-rated impact of weight on health. CONCLUSIONS: Persons with chronic health conditions and with obesity or overweight benefit at least as much as those with a healthy BMI from iCBT programs targeting psychological adjustment to chronic illness, even without changes in BMI. iCBT programs may be an important component in the self-management of this population, and may address barriers implicated in health behaviour change.

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.

Predictors of functional impairment at assessment and functional improvement after treatment at a national digital mental health service.

Mental disorders are associated with impairment to daily functioning, which affects both the individual and society. Despite this, most research on treatment outcome only report symptom change. Self-reported days out of role (DOR) is a simple measure of functional impairment used in many population studies. The current study sought to report on the degree of functional impairment measured by DOR in a clinical sample at assessment, the factors associated with this impairment, the predictors of functional improvement after treatment and the relationship between symptomatic and functional change. Using a prospective uncontrolled observational cohort study design with a sample of 17,813 patients accessing a digital mental health service (DMHS), we examined self-reported demographic, psychosocial and clinical data. Using a series of univariate regression models and multivariate classification algorithms, we found that baseline DOR was associated with age, employment and relationship status, symptom severity, symptom chronicity and with the presence of several psychosocial difficulties. Baseline DOR was best predicted by older age, disability payments, higher symptom severity and increasing number of endorsed psychosocial difficulties (R2 = 32.7 %). Forty-one per cent of the sample experienced a >50 % or greater reduction in DOR following treatment. Those who were separated, unemployed or on disability payments, or with severe and chronic depression, experienced the greatest reductions in DOR after treatment. Changes in functioning were independent of changes in symptoms, highlighting the importance of functional impairment as a treatment outcome. This study found that many of the patients who access DMHS have significant levels of functional impairment, a large proportion obtain functional improvement after treatment, and improvement in function after treatment was independent of improvement in symptoms.

Can Internet-Delivered Pain Management Programs Reduce Psychological Distress in Chronic Pain? Exploring Relationships Between Anxiety and Depression, Pain Intensity, and Disability.

BACKGROUND: Adults with chronic pain who also report high pain intensity and disability are more likely to experience depression and anxiety symptoms. The present study examined changes in anxiety and depression symptoms after an Internet-delivered pain management program based on baseline pain intensity and disability severity categories. METHODS: We conducted a secondary analysis of data from four randomized controlled trials (N = 1,333). RESULTS: Greater pain intensity and disability were associated with increased odds of elevated anxiety or depression symptoms at baseline. Treatment led to greater reductions in anxiety and depression symptoms compared with a waitlist control, and these improvements occurred irrespective of baseline pain intensity or disability severity. Those individuals who reported ≥30% improvements in pain intensity or disability after treatment were more likely to also report ≥30% improvements in psychological symptoms. Importantly, most participants who achieved ≥30% improvements in depression and anxiety had not experienced such improvements in pain intensity or disability. CONCLUSION: These findings suggest that emerging Internet-delivered pain management programs can lead to reductions in psychological distress even when pain intensity and disability are severe or do not improve with treatment. This indicates the value of such treatments in treating distress and improving mental health in people with chronic pain.

The timing and magnitude of symptom improvements during an Internet-delivered transdiagnostic treatment program for anxiety and depression.

OBJECTIVE: In face-to-face treatments, mental health symptoms improve rapidly across the first few treatment sessions, and the pace of improvement slows with additional sessions. Some individuals also report clinically meaningful symptom improvements after only two or three treatment sessions. As the rate of symptom change has been given limited attention within digital treatments, the present study investigated the timing and magnitude of symptom change during an 8-week online treatment for anxiety and depression. METHOD: Three adult samples were derived from previous randomized controlled trials: generalized anxiety disorder (n = 165), major depression (n = 149), and mixed anxiety/depression (n = 262). Symptom scores were compared between consecutive weeks of treatment, and we examined the proportion of individuals who achieved a ≥ 25% or ≥ 50% improvement in symptoms each week. RESULTS: Across all three samples, symptoms improved more rapidly during the first half of treatment compared to the second half of treatment. Within the first 4 weeks, over half of the participants had experienced a ≥ 25% improvement in symptoms, and approximately a third of participants had experienced a ≥ 50% improvement in symptoms. This pattern of change was found irrespective of diagnostic status or outcome measure. CONCLUSIONS: A substantial number of people who receive internet-delivered treatments appear to experience rapid, large, and clinically significant symptom improvement early in treatment. These findings add to our theoretical understanding of symptom improvements during psychotherapy, and further research investigating the mechanisms of such change will inform the development of more effective treatments.

Sudden gains in therapist-guided versus self-guided online treatments for anxiety or depression.

OBJECTIVE: Sudden gains are large, rapid, and sustained symptom improvements, and are associated with improved treatment outcomes across a range of mental health problems. Current theories suggest that therapists are required for sudden gains to be sustained, and to result in improved treatment outcomes. We compared the prevalence and consequences of sudden gains in therapist-guided versus self-guided internet-delivered treatments for anxiety and depression. METHOD: Samples from four previous randomized controlled trials were analyzed: generalized anxiety disorder (n = 259), panic disorder (n = 109), social anxiety disorder (n = 175), and major depressive disorder (n = 209). The prevalence, timing, and reversal rates of sudden gains were compared across therapist-guided and self-guided groups. Generalized estimating equations were used to examine the impact of guidance level and sudden gain status on posttreatment outcomes. RESULTS: Sudden gains were similarly prevalent in therapist-guided and self-guided treatments. In all four diagnostic samples, sudden gains most frequently occurred between Weeks 2 and 3 of treatment, and the rate of reversals did not differ based on the presence of guidance. The association between sudden gains and treatment outcome varied by disorder, such that sudden gains were associated with improved outcomes (irrespective of guidance condition) for participants with social anxiety disorder and major depression, but not generalized anxiety disorder or panic disorder. CONCLUSIONS: Sudden gains can occur, and are maintained, during internet-delivered psychotherapy even in the absence of therapist guidance. Furthermore, sudden gains may be associated with different patterns of symptom improvement depending on diagnostic presentation. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

A meta-analytic review of randomized clinical trials of online treatments for anxiety: Inclusion/exclusion criteria, uptake, adherence, dropout, and clinical outcomes.

Over the last decade there has been rapid growth in the number of clinical trials examining internet-delivered interventions for anxiety. While there have been numerous analyses of treatment efficacy, few studies have examined treatment engagement. The current meta-analysis examined participant eligibility, uptake, adherence, and drop-out in clinical trials of internet-delivered treatments for anxiety. This meta-analysis used random effects models to obtain estimates of participant inclusion, uptake, adherence, drop-out, and within-group treatment effect size. Moderator analyses examined the effects of anxiety disorder type, treatment type, and level of clinician guidance. After screening, 140 trials with 199 treatment arms (N = 11,021) were included. An average of 46% (95% CI 42, 50) of interested people were included in the clinical trials. In the active treatment arms, 98% (95% CI 97, 99) of participants began treatment, 81% (95% CI 78, 85) of the assigned treatments were completed, 21% (95% CI 18, 23) of individuals dropped out at post-treatment based on questionnaire non-completion, and an overall within-group effect size of g = 1.03 (95% CI 0.94, 1.13) was obtained. Several moderators of interest were significant (e.g., clinical guidance, anxiety disorder type), and there was substantial heterogeneity in estimates. In conclusion, a large number of inclusion and exclusion criteria have been used in trials of internet-delivered treatments for anxiety. Once recruited into a trial, however, most people appear to begin, adhere, and complete internet-delivered treatment for anxiety. Further research exploring various eligibility criteria and their impact on engagement and efficacy is warranted.

Examining Change in the Frequency of Adaptive Actions as a Mediator of Treatment Outcomes in Internet-Delivered Therapy for Depression and Anxiety.

Adaptive actions, including healthy thinking and meaningful activities, have been associated with emotional wellbeing. The Things You Do Questionnaire-21 item (TYDQ-21) has recently been created to measure the frequency of such actions. A study using the TYDQ-21 found that adaptive actions increased across Internet-delivered therapy for symptoms of depression and anxiety, and higher TYDQ-21 scores were associated with lower psychological distress at post-treatment. The current study examined the relationships between adaptive actions and psychological distress among adults (n = 1114) receiving Internet-delivered therapy as part of routine care in Canada, and explored whether adaptive actions mediated reductions in depression and anxiety. As hypothesised, adaptive actions increased alongside reductions in depression and anxiety symptoms from baseline to post-treatment. Treatment effects were consistent when the intervention was provided with regular weekly therapist support or with optional weekly therapist support, and some (but not all) types of adaptive actions had a mediating effect on change in depressive symptoms. The present findings support further work examining adaptive actions as a mechanism of change in psychotherapy, as well as the utility and scalability of Internet-delivered treatments to target and increase adaptive actions with the aim of improving mental health.

Measures of Daily Activities Associated With Mental Health (Things You Do Questionnaire): Development of a Preliminary Psychometric Study and Replication Study.

BACKGROUND: A large body of research has identified modifiable cognitions and behaviors (actions) associated with psychological health. However, little is known regarding the actions that are most strongly associated with psychological health or the frequency with which they should be performed. OBJECTIVE: This paper described 2 studies that used survey methodology to create the Things You Do Questionnaire (TYDQ), which aims to identify and rank actions (items) and domains of actions (factors) most strongly associated with psychological health. METHODS: We used digital marketing strategies to recruit Australian adult participants, who were asked to complete 2 web-based surveys comprising versions of the TYDQ; validated measures of depression, anxiety, and satisfaction with life; and demographic questions. In study 1, a total of 3040 participants rated how often they performed each of the 96 items comprising the TYDQ. This design was replicated in study 2, in which a 59-item version of the TYDQ was completed by 3160 participants. In both studies, the factor structure and validity were examined, as were the associations between individual TYDQ items and 3 mental health outcomes: depression, anxiety, and satisfaction with life. RESULTS: In study 1, factor analyses revealed that a 5-factor model comprising 27 items achieved an optimum balance between brevity and variance and accounted for 38.1%, 31.4%, and 33.2% of the variance in scores on measures of depression, anxiety, and satisfaction with life, respectively. The factors were interpreted as realistic thinking, meaningful activities, goals and plans, healthy habits, and social connections. These 5 factors were more strongly associated with psychological health than those such as practicing kindness, exercising gratitude, and practicing spirituality. This pattern of results was replicated across gender, age groups, and depression severity. The 5-factor solution found in study 1 was replicated in study 2. Analyses revealed that a 21-item version accounted for 46.8%, 38.2%, and 38.1% of the variance in scores on measures of depression, anxiety, and satisfaction with life, respectively. CONCLUSIONS: These findings indicate that some actions are more strongly associated with psychological health than others and that these activities fall within 5 broad domains, which represent skills often taught in psychological treatments. Subsequent studies are planned to explore the reliability of these items and results in other samples and to examine patterns of change in scores during treatment for anxiety and depression. If replicated, these efforts will assist in the development of new psychological interventions and provide an evidence base for public mental health campaigns designed to promote good mental health and prevent the emergence of common mental disorders.

Understanding the untreated course of anxiety disorders in treatment-seeking samples: A systematic review and meta-analysis.

BACKGROUND: Very little is known about the course of anxiety disorders when they go untreated, despite the significant theoretical and practical value of this information, such as for treatment planning and benchmarking purposes. This meta-analysis aimed to examine the course of anxiety disorders in treatment-seeking samples using the control groups of treatment studies for anxiety disorders. METHODS: Following pre-registration, we systematically searched the literature for RCTs of treatment for anxiety disorders. Studies were included if they randomised participants to a control arm, where treatment was not received (i.e. waitlist control or no-treatment control). Meta-analyses were conducted to determine the magnitude of symptom change over the control period (Hedges' g), and rate of response (pooled prevalence). Effects were compared between anxiety disorders, alongside other potential moderators. RESULTS: Following search and screening, 173 RCTs met criteria (n = 15,250) for data extraction. Overall, untreated participants demonstrated significant, but small improvements to anxiety symptoms (g = 0.17, 95% CI 0.14, 0.21). Significant differences were observed between anxiety disorders, and according to other methodological features of the included trials. CONCLUSIONS: Results suggest that anxiety disorders are unlikely to remit without treatment, with some disorders remitting to a lesser extent than others. While this review is limited to a treatment-seeking sample, results provide theoretical and practical value for researchers and treatment providers.
