Correlates of depression in individuals with obsessive compulsive disorder.

The existing literature examining the correlates of depression in individuals with obsessive compulsive disorder (OCD) is characterized by inconsistent results. The aim of the current study was to replicate and extend the literature by exploring whether various clinical and demographic factors are related to the occurrence of depression in a large sample (N = 243) of individuals with OCD (M age = 33.00; SD = 12.47; 74% female). Individuals with OCD who had elevated comorbid depressive symptoms [Patient Health Questionnaire-9 item (PHQ-9) ≥10] scored significantly higher on all OCD symptom subtypes (p range < .001-.048), had greater obsessive and compulsive severity (ps < .001), scored higher on perfectionism (p < .001), and had higher disgust sensitivity and propensity scores (ps < .001) compared with individuals who did not have comorbid depressive symptoms (PHQ-9 < 10). Of these variables, obsession severity (ß = 0.22, p = .004), OCD contamination subtype (ß = 0.16, p = .032) and perfectionism (ß = 0.25, p < .001) were found to be associated with depressive symptoms on the PHQ-9. The findings of this study contribute to the understanding of factors which are associated with depression comorbidity in individuals with OCD.

Predictors of outcome in self-guided internet-delivered cognitive-behavior therapy for obsessive-compulsive disorder: A preliminary investigation.

Internet-delivered cognitive-behavioral therapy (ICBT) is an effective treatment for obsessive-compulsive disorder (OCD). ICBT can be delivered in a self-guided or clinician-guided format. While a literature is emerging on the predictors of response to clinician-guided ICBT, there is a lack of research examining the predictors of response to self-guided ICBT. The aim of the present study was to examine predictors of outcome in a large sample of participants with OCD who commenced a self-guided ICBT intervention. One hundred and fifty-seven participants (Mage = 34.82; SD = 10.49; 78% female) were included in the study. Regression analyses were conducted to determine clinical and demographic predictors of (1) posttreatment symptom severity and (2) a clinically meaningful treatment response for both the intention-to-treat (ITT) and completer samples. The regression models significantly predicted posttreatment outcome for both the ITT (F(8, 148) = 15.844, p < .001) and completer sample (F(8, 101) = 5.929, p < .001), explaining 46% and 34% of the variance respectively. Higher baseline OCD severity, younger age, experiencing higher contamination or symmetry symptoms, and a history of past treatment were all found to be significantly associated with higher posttreatment severity in the ITT sample. In the completer sample only higher baseline OCD severity and severity of harm-related obsessions and checking compulsions was significantly associated with higher posttreatment severity. When predicting treatment response the regression models for both the ITT and completer sample were nonsignificant.

Things You Do: A randomized controlled trial of an unguided ultra-brief intervention to reduce symptoms of depression and anxiety.

The 'Things You Do' encompass five types of actions that are strongly associated with good mental health: Healthy Thinking, Meaningful Activities, Goals and Plans, Healthy Habits, and Social Connections. Ultra-brief interventions which increase how often people perform these actions may decrease depression and anxiety. A two-arm randomized controlled trial (N = 349) compared an unguided ultra-brief intervention based on the 'Things You Do' against a waitlist control. The intervention included one online module, two practice guides, and four weeks of daily text messages. The primary timepoint was 5-weeks post-baseline. The intervention resulted in moderate reductions in depression (d = 0.51) and anxiety (d = 0.55) alongside moderate increases in the frequency of Things You Do actions (d = 0.54), compared to controls. No significant change in number of days out of role or life satisfaction were observed. Treatment completion was high (92 %), most participants reported being satisfied with the treatment (66 %), and improvements were maintained at 3-month follow-up. This study demonstrated that an automated ultra-brief 'Things You Do' intervention resulted in clinically significant reductions in depression and anxiety. Ultra-brief interventions may provide a scalable solution to support individuals who are unlikely to engage in longer forms of psychological treatment.

The association between physical intervention use and treatment outcomes in patients participating in an online and psychologically informed pain management program.

BACKGROUND: The availability of multidisciplinary care for the management of chronic pain is uncommon outside specialist clinics. The current study aims to determine the physical intervention use of patients participating in an online psychological pain management program and whether exposure to physical interventions in these patients alters treatment outcomes compared to patients who do not access physical interventions. METHODS: Data were obtained from two previously published randomised control trials of an online psychological pain management program. Physical intervention exposure (category: None, 1-3, 4+ sessions) was assessed at baseline, post-treatment and at 3-month follow-up. Primary outcomes included depression, anxiety, pain intensity and pain-related disability. Generalised estimating equation models were used to compare treatment outcomes between those with different physical intervention frequencies and period of exposure. We assessed whether changes in primary outcomes differed (moderated) depending on the period and category of physical intervention exposure. RESULTS: N = 1,074 patients completed the baseline questionnaire across both RCTs, of whom 470 (44%) reported physical intervention use at baseline, 383 (38%) at post-treatment and 363 (42%) at 3-month follow-up. On average, there were moderate-large reductions from baseline to post-treatment with respect to all outcomes (Cohen's d = 0.36-0.82). In all outcomes, the interaction of time by physical intervention exposure was statistically non-significant. CONCLUSION: A substantial proportion of patients who participated in a psychologically informed pain management program were establishing, continuing, or stopping additional physical interventions. The frequency and period of exposure to physical interventions did not appear moderate treatment outcomes.

Internet-Delivered Psychological Pain Management: A Prospective Cohort Study Examining Routine Care Delivery by a Specialist Regional Multidisciplinary Pain Service.

Several clinical trials have demonstrated the effectiveness of internet-delivered psychological-based pain management programs (PMPs). However, to date, no large studies have reported the outcomes of PMPs when delivered by specialist multidisciplinary pain services in routine care. The present study reports (n = 653) the outcomes of an internet-delivered PMP provided as routine care by a specialist Australian regional pain service over a 6-year period. High levels of treatment commencement (85%) and completion (72%) were observed, with more than 80% of patients reporting they were satisfied with the intervention. Clinical improvements were observed from pretreatment to post-treatment (% change, 95% confidence intervals (CI)) in pain-related disability (8.8%; 4.5, 12.8), depression (28.4%; 23.0, 33.4), anxiety (21.9%; 14.6, 28.5), and pain intensity (7%; 3.5, 10.5), which were maintained to 3-month follow-up. At 3-month follow-up, 27% (23, 31), 46% (41, 51), 44% (39, 49), and 22% (19, 26) reported clinically meaningful (defined as ≥ 30%) improvements in pain-related disability, depression, anxiety, and pain intensity, respectively. These results were obtained with relatively little therapist time per patient (M = 30.0, (standard deviation) SD = 18.8) to deliver the intervention. The current findings highlight the potential of internet-delivered PMPs as part of the services provided by specialist pain services, particularly those servicing large geographical regions and for patients unable to travel to clinics for face-to-face care. PERSPECTIVE: This study reports the outcomes of the routine delivery of an internet-delivered psychological PMP by a specialist pain service. The findings highlight the potential of this model of care when provided by specialist pain services, particularly for patients not unable to attend and not requiring intensive face-to-face care.

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.

Outcomes of transdiagnostic internet-delivered cognitive behavioural therapy tailored to public safety personnel: A longitudinal observational study.

First responders and other public safety personnel (PSP) experience high rates of mental health problems and face barriers to accessing mental healthcare. Internet-delivered cognitive behavioural therapy (ICBT) is an effective and accessible treatment for various mental health concerns. Canadian PSP report favorable attitudes toward ICBT, and preliminary outcomes demonstrate that they benefit from it. Expanding on this research, the current study consisted of a longitudinal observational study of 560 Canadian PSP who participated in ICBT. It was designed to assess the longer term effectiveness of ICBT and moderators of outcomes by gender, linguistic and occupational group, and years of occupational experience. We evaluated symptom change at 8, 26, and 52 weeks post-enrollment, and results among PSP who had elevated clinical scores, showed large reductions (Hedges' g) in symptoms of depression (g = 1.3), anxiety (g =1.48), posttraumatic stress (g =1.24), panic (g =1.19), and anger (g =1.07) and moderate reductions in symptoms of social anxiety (g =.48-.56). Moderator analyses revealed modest differences in pre-treatment symptoms among certain groups but no group differences in symptom change over time. Clients showed good completion of treatment materials and reported high treatment satisfaction. The results suggest further study of ICBT tailored to PSP is warranted, including evaluating ICBT tailored for PSP in other countries.

A pilot study examining whether restricting and resuming specific actions systematically changes symptoms of depression and anxiety. A series of N-of-1 trials.

Anxiety and depressive disorders are highly prevalent and a leading cause of disability. Understanding how symptoms develop could lead to new preventive and clinical interventions. This pilot study examined whether systematically restricting specific behaviours (target actions) associated with good psychological health would increase psychological symptoms in healthy participants, and whether resuming those actions would reduce symptoms to baseline levels. Twelve adults participated in a series of N-of-1 trials comprising baseline (A), restriction (B) and recovery (C) phases. Outcomes were assessed weekly using measures of depression (PHQ-9), anxiety (GAD-7), and a validated 15-item measure of target actions (Big 5). Symptoms of depression and anxiety increased significantly from Phase A to Phase B and returned to baseline by the end of Phase C. Increased symptoms during Phase B were only observed in participants who restricted actions by more than 25%. Symptom increases were evident within 2 weeks of restriction, but most participants appeared to take longer to recover to baseline levels. This study demonstrates that reducing the frequency of specific actions may increase symptoms of anxiety and depression, which is reversed when those actions are resumed. This contributes to our understanding of the aetiology, maintenance, and recovery from depression, anxiety, and possibly other disorders.

Satisfaction, engagement, and outcomes in internet-delivered cognitive behaviour therapy adapted for people of diverse ethnocultural groups: an observational trial with benchmarking.

Introduction: Depression and anxiety are the most common mental health disorders worldwide. Internet-Delivered Cognitive Behaviour Therapy (ICBT) can reduce barriers to care to broad cross sections of the population. However, People of Diverse Ethnocultural Backgrounds (PDEGs) other than White/Caucasian underutilize mental health services and are under represented in clinical trials of psychological interventions. Methods: To address this research gap we adapted an evidence-based ICBT program for PDEGs. The current pilot study explores the engagement, satisfaction, and effectiveness in the adapted ICBT program by PDEGs (N=41) when benchmarked against a sample of PDEGs (N=134) who previously completed a non-adapted version of the ICBT program. Results: An intent-to-treat analyses showed that the adapted ICBT program is effective in reducing anxiety and depression symptoms among PDEGs. Large within-group pre-to post-treatment Cohen's effect sizes of d = 1.23, 95% CI [0.68, 1.77] and d = 1.24, 95% CI [0.69, 1.79] were found for depression and anxiety, respectively. Further, 81.8% of the PDEGs who received the adapted ICBT reported overall satisfaction, 90.9% reported increased confidence in managing symptoms, and 70.7% completed majority of the psychoeducational lessons in the ICBT program. Conclusion: No statistically significant differences in the clinical outcomes, engagement, and satisfaction were found between the pilot study and benchmark sample. Future directions for ICBT research with PDEGs are described. Clinical trial registration: https://beta.clinicaltrials.gov/study/NCT05523492, identifier NCT05523492.

Comparative effectiveness of digital mental healthcare models for adults with epilepsy: A study protocol of a randomized controlled trial.

OBJECTIVE: Mental health complaints are prevalent among people with epilepsy, yet there are major barriers that prevent access to psychological care, including high out-of-pocket costs and a lack of accessible specialized services. The purpose of the current study is to examine the comparative efficacy, acceptability, cost-effectiveness, and long-term outcomes of a digital psychological intervention when delivered under two models of care (i.e., guided vs. unguided) in supporting the mental health and functioning of adults with epilepsy. METHOD: Approximately 375 participants across Australia will be enrolled. Eligible participants will have a confirmed diagnosis of epilepsy, experience difficulties with their emotional health, be at least 18 years of age, and live in Australia. Participants will be randomized (2:2:1) to receive the Wellbeing Neuro Course, a 10-week internet-delivered program, with (i.e., guided) or without guidance by a mental health clinician (i.e., unguided), or be allocated to a treatment-as-usual waiting-list control group. Participants will complete online questionnaires at pre-, post-treatment, and 3- and 12-month follow-up and consent to have their data linked to their medical records to capture healthcare system resource use and costs. ANALYSIS: Primary outcome measures will be symptoms of depression and anxiety. A cost-utility analysis will be undertaken using the Australian healthcare system perspective and according to current economic evaluation guidelines. Resource use and costs to the healthcare system during the study period will be captured via data linkage to relevant administrative datasets in Australia. SIGNIFICANCE: The results of this trial will provide important data concerning the relative outcomes of these different models of care and will inform the integration of digital psychological interventions translation into healthcare services. ETHICS AND DISSEMINATION: The Human Research Ethics Committee of Macquarie University approved the proposed study (Reference No: 520231325151475). The results will be disseminated through peer-reviewed publication(s). ANZCTR TRIAL REGISTRATION NUMBER: ACTRN12623001327673. PLAIN LANGUAGE SUMMARY: This study seeks to find out if a 10-week online psychological treatment can improve the mental health and well-being of Australian adults with epilepsy. Around 375 participants will be randomly assigned to different groups: one will receive treatment with guidance from mental health clinician (guided group), one without guidance (unguided group), and one starting later (waiting control group). All participants will fill out the same outcome measures online. The main goal of this research is to compare these groups and assess how well the treatment works in improving mental health outcomes.

Efficacy and acceptability of a self-guided internet-delivered cognitive-behavioral educational program for obsessive-compulsive symptoms with international recruitment.

Cognitive-behavioural therapy is an effective treatment for obsessive-compulsive disorder (OCD). However, there are many barriers in accessing this treatment, with stigma being a particularly prominent barrier for many patients. Self-guided internet-delivered cognitive-behavioural therapy (ICBT), which does not require any contact with a therapist, has the potential to overcome this barrier. However, there is limited research on the efficacy of self-guided ICBT for OCD. The aim of the current study was to examine the efficacy of self-guided ICBT for OCD in a large international sample. Two hundred and sixteen participants were included in the study (Mage = 34.00; SD = 12.57; 72.7% female). On the primary outcome measure, the Yale-Brown Obsessive-Compulsive Scale (YBOCS), a medium within-group effect size was found from pre-treatment to post-treatment (g = 0.63), and a large within-group effect size was found from pre-treatment to 3-month follow-up (g = 0.98). Approximately one-quarter to one-third of participants met criteria for clinically significant improvement at post-treatment and 3-month follow-up (11% and 17% met criteria for remission at post-treatment and 3-month follow-up, respectively). These results demonstrate that self-guided ICBT may be an efficacious treatment for individuals with OCD who cannot or do not wish to engage with a mental health professional, resulting in medium to large effect sizes.

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.

One step at a time. Shaping consensus on research priorities and terminology in telehealth in musculoskeletal pain: an international modified e-Delphi study.

BACKGROUND: Telehealth has emerged as an alternative model for treatment delivery and has become an important component of health service delivery. However, there is inconsistency in the use of terminologies and a lack of research priorities in telehealth in musculoskeletal pain. The purpose of this international, multidisciplinary expert panel assembled in a modified three-round e-Delphi survey is to achieve a consensus on research priorities and for the standard terminology for musculoskeletal pain telehealth practice. METHODS: In this international modified e-Delphi survey, we invited an expert panel consisting of researchers, clinicians, consumer representatives, industry partners, healthcare managers, and policymakers to participate in a three-round e-Delphi. Expert panels were identified through the Expertscape website, PubMed database, social media, and a snowball approach. In Round 1, potential research priorities and terminologies were presented to panel members. Panel members rated the agreement of each research priority on a 5-point Likert scale and an 11-point numerical scale, and each terminology on a 5-point Likert scale for the "telehealth in musculoskeletal pain " field over rounds. At least 80% of the panel members were required to agree to be deemed a consensus. We analyzed the data descriptively and assessed the stability of the results using the Wilcoxon matched-pairs signed rank test. RESULTS: We performed an international e-Delphi survey from February to August 2022. Of 694 invited people, 160 panel members participated in the first round, 133 in the second round (83% retention), and 134 in the third round (84% retention). Most of the panel members were researchers 76 (47%), clinicians 57 (36%), and consumer representatives 9 (6%) of both genders especially from Brazil 31 (19%), India 22 (14%), and Australia 19 (12%) in the first round. The panel identified fourteen telehealth research priorities spanned topics including the development of strategies using information and communication technology, telehealth implementation services, the effectiveness and cost-effectiveness of telehealth interventions, equity of telehealth interventions, qualitative research and eHealth literacy in musculoskeletal pain conditions from an initial list of 20 research priorities. The consensus was reached for "digital health" and "telehealth" as standard terminologies from an initial list of 37 terminologies. CONCLUSION: An international, multidisciplinary expert consensus recommends that future research should consider the 14 research priorities for telehealth musculoskeletal pain reached. Additionally, the terms digital health and telehealth as the most appropriate terminologies to be used in musculoskeletal telehealth research.

A cross-sectional study of existential concerns and fear of progression in people with Rheumatoid Arthritis.

OBJECTIVES: People with rheumatoid arthritis (RA) have higher levels of fear of disease progression (FOP) than cancer survivors. In cancer, FOP is inextricably linked with existential concerns. However, this has not been investigated in people with RA. METHODS: We recruited 165 people with RA (96%F) who volunteered for a treatment trial of psychological intervention. Participants completed the Existential Concerns Questionnaire (ECQ) and questionnaires measuring constructs associated with FOP in cancer. We created groups of people with RA, with and without clinically significant levels of FOP (clinical and control groups) and compared their existential concerns. We hypothesized that existential concerns would add to the variance in FOP over and above pain, psychopathology, and disability. RESULTS: Nearly two-thirds of people with RA scored in the clinical range for FOP. The clinical group had higher levels of all existential concerns than the control group. When subscales of the ECQ were entered into a multiple regression with FOP as the dependent variable, death anxiety, meaninglessness and guilt domains accounted for significant variance in FOP. Moreover, when added to a regression equation controlling all other variables, existential concerns continued to account for unique variance in FOP (t = 2.712, p = 0.007). CONCLUSION: Existential concerns were strongly associated with FOP. While this cross-sectional study cannot determine whether existential concerns underlie FOP in RA, these results show robust relationships that warrant future investigation.

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.

Guided versus self-guided internet delivered cognitive behavioural therapy for diagnosed anxiety and related disorders: a preliminary meta-analysis.

Guided and self-guided internet-delivered cognitive-behavioural therapy (ICBT) has been demonstrated to be efficacious in the treatment of anxiety and related disorders (ARDs). The aim of the current study was to examine the efficacy of guided and self-guided ICBT for adults diagnosed with ARDs using a meta-analytic synthesis of randomised controlled trials directly comparing the two treatment approaches. Eleven studies (n = 1414) were included. There was a small, but significantly pooled between-group effect size at post-treatment (g = 0.16; 95% CI: 0.03-0.28) favouring guided ICBT. At follow-up, the between-group effect size was small and non-significant (g = 0.13; 95% CI: -0.04-0.30). Gender distribution moderated outcome at post-treatment (higher proportions of females resulted in a smaller between-group effect size). Type of support provided in the guided-treatment arm moderated treatment outcome at follow-up (those receiving synchronous support had a larger between-group effect size). Amount of guidance in the guided-treatment arm moderated effect sizes at post-treatment and follow-up (more guidance leading to larger between-group effect sizes). Automated reminders, disorder type, and treatment length did not moderate outcomes. The results suggest that guided and self-guided ICBT interventions result in similar outcomes, however guided interventions may be marginally more effective in the short term.

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.
