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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The role of therapist support on the efficacy of an internet-delivered stress recovery intervention for healthcare workers: a randomized control trial.

Internet-delivered CBT interventions effectively improve different aspects of mental health, although the therapist's role remains unclear. The aim of this trial was to evaluate the efficacy of a therapist-supported 6-week internet-delivered intervention in improving stress recovery among healthcare workers compared to a group with optional therapist support. A total of 196 participants were recruited and randomly allocated to regular therapists' support or optional therapists' support groups. The primary outcome measure was the Recovery Experiences Questionnaire (REQ), developed to assess four components of stress recovery: psychological detachment, relaxation, mastery, and control. Secondary outcomes measured perceived stress (PSS-10), anxiety (GAD-7), depression (PHQ-9), and psychological well-being (WHO-5). All four stress recovery skills improved significantly after participating in the intervention at a 3-month follow-up, with small to medium effects (0.27-0.65) in both groups. At follow-up, we also found a significant reduction in perceived stress, depression, and anxiety in both groups, as well as an improvement in psychological well-being. The results indicate that ICBT can be effective in improving stress recovery skills among healthcare workers with optional support from the therapist, provided at the participants' request. This RCT suggests that optional therapist support could meet participants' needs and reduce resources needed in routine care.

Predictors of response to cognitive behavioural therapy (CBT) for individuals with obsessive-compulsive disorder (OCD): a systematic review.

BACKGROUND: Cognitive behavioural therapy (CBT) is considered the first-line treatment for obsessive-compulsive disorder (OCD). However, some individuals with OCD remain symptomatic following CBT, and therefore understanding predictors of outcome is important for informing treatment recommendations. AIMS: The current study aimed to provide the first synthesis of predictors of outcome following CBT for OCD in adults with a primary diagnosis of OCD, as classified by DSM-5. METHOD: Eight studies (n=359; mean age range=29.2-37.7 years; 55.4% female) were included in the systematic review. RESULTS: Congruent with past reviews, there was great heterogeneity of predictors measured across the included studies. Therefore, a narrative synthesis of findings was conducted. Findings from this systematic review indicated that some OCD-related pre-treatment variables (i.e. pre-treatment severity, past CBT treatment, and levels of avoidance) and during treatment variables (i.e. poor working alliance and low treatment adherence) may be important to consider when making treatment recommendations. However, the results also indicate that demographic variables and psychological co-morbidities may not be specific predictors of treatment response. CONCLUSIONS: These findings add to the growing body of literature on predictors of CBT treatment outcomes for individuals with OCD.

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.

Utilization, Patient Characteristics, and Longitudinal Improvements among Patients from a Provincially Funded Transdiagnostic Internet-delivered Cognitive Behavioural Therapy Program: Observational Study of Trends over 6 Years.

OBJECTIVE: There is strong evidence supporting internet-delivered cognitive behaviour therapy (iCBT) and consequently growing demand for iCBT in Canada. Transdiagnostic iCBT that addresses both depression and anxiety is particularly promising as it represents an efficient method of delivering iCBT in routine care. The Online Therapy Unit, funded by the Saskatchewan government, has been offering transdiagnostic iCBT for depression and anxiety since 2013. In this article, to broadly inform implementation efforts, we examined trends in utilization, patient characteristics, and longitudinal improvements for patients receiving transdiagnostic iCBT over 6 years. METHODS: Patients who completed telephone screening between November 2013 and December 2019 were included in this observational study. Patients provided demographics and mental health history at screening and completed measures at pre-treatment, post-treatment and at 3- to 4-month follow-up. Treatment engagement and satisfaction were assessed. RESULTS: A total of 5,321 telephone screenings were completed and 4,283 of patients were accepted for treatment over the 6-year period (80.5% acceptance). The most common reason for referral to another service was high suicide risk/severe symptoms (47.1%). Examination of trends showed growing use of transdiagnostic iCBT over time (37% increase per year). There was remarkable stability in patient characteristics across years. Most patients were concurrently using medication (57.3%) with 11.9% reporting using iCBT while on a waiting list for face-to-face treatment highlighting the importance of integrating iCBT with other services. Consistent across years, large improvements in depression and anxiety symptoms were found and maintained at 3- to 4-month follow-up. There was strong patient engagement with iCBT and positive ratings of treatment experiences. CONCLUSIONS: As there is growing interest in iCBT in Canada, this large observational study provides valuable information for those implementing iCBT in terms of likely user characteristics, patterns of use, and improvements. This information has potential to assist with resource allocation and planning in Canada and elsewhere.

Examining the psychometric properties of brief screening measures of depression and anxiety in chronic pain: The Patient Health Questionnaire 2-item and Generalized Anxiety Disorder 2-item.

OBJECTIVE: Individuals with chronic pain experience anxiety and depressive symptoms at rates higher than the general population. The Patient Health Questionnaire 2-item (PHQ-2) and Generalized Anxiety Disorder 2-item (GAD-2) are brief screening measures of depression and anxiety, respectively. These brief scales are well-suited for use in routine care due to their brevity and ease of administration, yet their psychometric properties have not been established in heterogeneous chronic pain samples when administered over the Internet. MATERIALS AND METHODS: Using existing data from randomized controlled trials of an established Internet-delivered pain management program (n = 1333), we assessed the reliability, validity, diagnostic accuracy, and responsiveness to treatment change in the PHQ-2 and GAD-2, as well as the long-form counterparts. Exploratory analyses were conducted to obtain cutoff scores using those participants with diagnostic data (n = 62). RESULTS: The PHQ-2 and GAD-2 demonstrated appropriate reliability (eg, Cronbach's α = 0.79-0.84), validity (eg, higher scores in individuals with a diagnosis; p < 0.001), and responsiveness to treatment change (eg, pre- to post-treatment scores, p < 0.001). The psychometric properties of the short forms compared well with the longer forms. Cutoff scores on the short forms were consistent with general population samples, while cutoff scores on the long forms were higher than previously observed using general population samples. All four scales favored specificity over sensitivity. CONCLUSIONS: The PHQ-2 and GAD-2 demonstrated acceptable psychometric properties in the current sample, as did the long forms. Based on our findings, the PHQ-2 and GAD-2 can be used as screening tools with chronic pain samples when administered over the Internet.

Preventing depression in older people with multimorbidity: 24-month follow-up of a trial of internet-delivered cognitive behaviour therapy.

BACKGROUND: older people coping with the impacts of living with multimorbidity are at increased risk of developing a depressive disorder. OBJECTIVE: this article reports the 24-month results of a randomised controlled trial of an internet-delivered cognitive behaviour therapy, which aimed to test whether depressive disorders could be prevented in this population. PARTICIPANTS: community-based participants aged 65 years and over, who had two or more chronic physical health conditions and were assessed as having no current depressive disorder. METHODS: in total, 302 participants were randomised to an 8-week, five-lesson, internet-delivered intervention program (n = 150) or treatment as usual (TAU, n = 152). The primary outcomes were cases of depressive disorder, assessed post-intervention and at 3-month intervals throughout the trial, and depressive symptoms, assessed at pre-intervention, post-intervention, 6, 12 and 24 months following the intervention. RESULTS: there were significantly fewer cases of depressive disorder in the intervention group (n = 23, 15%) compared with the TAU group (n = 41, 27%) during the 24 months after the intervention (χ2(1, N = 302) = 6.13, P = 0.013, odds ratio = 0.490 [95% confidence interval: 0.277, 0.867]), representing a 44% reduction in cases of depressive disorder. No differences were found on depressive symptoms at 24-month follow-up. Internet-delivered cognitive behaviour therapy had high engagement and acceptability. CONCLUSIONS: the results provide support that depressive disorders can be prevented in older people with multimorbidity through participation in internet-delivered cognitive behaviour therapy. With access to internet-delivered interventions in clinical care settings increasing, this has implications for older patient care where multimorbidity is extremely common.

Initial Outcomes of Transdiagnostic Internet-Delivered Cognitive Behavioral Therapy Tailored to Public Safety Personnel: Longitudinal Observational Study.

BACKGROUND: Canadian public safety personnel (PSP) experience high rates of mental health disorders and face many barriers to treatment. Internet-delivered cognitive behavioral therapy (ICBT) overcomes many such barriers, and is effective for treating depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms. OBJECTIVE: This study was designed to fill a gap in the literature regarding the use of ICBT tailored specifically for PSP. We examined the effectiveness of a tailored ICBT program for treating depression, anxiety, and PTSD symptoms among PSP in the province of Saskatchewan. METHODS: We employed a longitudinal single-group open-trial design (N=83) with outcome measures administered at screening and at 8 weeks posttreatment. Data were collected between December 5, 2019 and September 11, 2020. Primary outcomes included changes in depression, anxiety, and PTSD symptoms. Secondary outcomes included changes in functional impairment; symptoms of panic, social anxiety, and anger; as well as treatment satisfaction, working alliance, and program usage patterns. RESULTS: Clients reported large symptom reductions on measures of depression and anxiety, as well as moderate reductions on measures of PTSD and secondary symptoms, except for social anxiety. Most clients who reported symptoms above clinical cut-offs on measures of depression, anxiety, and PTSD during screening experienced clinically significant symptom reductions. Results suggested good engagement, treatment satisfaction, and working alliance. CONCLUSIONS: Tailored, transdiagnostic ICBT demonstrated promising outcomes as a treatment for depression, anxiety, and PTSD among Saskatchewan PSP and warrants further investigation.

A comparison of the characteristics and treatment outcomes of migrant and Australian-born users of a national digital mental health service.

BACKGROUND: To explore the characteristics and compare clinical outcomes of non-Australian born (migrant) and Australian-born users of an Australian national digital mental health service. METHODS: The characteristics and treatment outcomes of patients who completed online treatment at the MindSpot Clinic between January 2014 and December 2016 and reported a country of birth other than Australia were compared to Australian-born users. Data about the main language spoken at home were used to create distinct groups. Changes in symptoms of depression and anxiety were measured using the Patient Health Questionnaire-9 Item (PHQ-9), and Generalized Anxiety Disorder Scale - 7 Item (GAD-7), respectively. RESULTS: Of 52,020 people who started assessment at MindSpot between 1st January 2014 and 22nd December 2016, 45,082 reported a country of birth, of whom 78.6% (n = 35,240) were Australian-born, and 21.4% (n = 9842) were born overseas. Of 6782 people who completed the online treatment and reported country of birth and main language spoken at home, 1631 (24%) were migrants, 960 (59%) were from English-speaking countries, and 671 (41%) were from non-English speaking countries. Treatment-seeking migrant users reported higher rates of tertiary education than Australian-born users. The baseline symptom severity, and rates of symptom reduction and remission following online treatment were similar across groups. CONCLUSIONS: Online treatment was associated with significant reductions in anxiety and depression in migrants of both English speaking and non-English speaking backgrounds, with outcomes similar to those obtained by Australian-born patients. DMHS have considerable potential to help reduce barriers to mental health care for migrants.

Guided internet-delivered cognitive-behaviour therapy for persons with spinal cord injury: a feasibility trial.

STUDY DESIGN: Observational pre-post study. OBJECTIVE: Guided internet-delivered CBT (ICBT) offers an alternative approach for mental health service delivery in the community for those with spinal cord injury (SCI). The feasibility and acceptability of guided ICBT programme is available for various chronic health conditions; however, the evidence related to SCI is limited. The primary aim of the current study was to examine feasibility and acceptability of a guided transdiagnostic ICBT programme for persons with SCI. SETTING: Community. METHODS: In this single-group pre-post study, persons with SCI (n = 20) living in the community were provided with a guided 8-week transdiagnostic ICBT programme for overall well-being. Study feasibility was examined by the following outcomes: patient recruitment, engagement, and attrition. Acceptability of the programme was evaluated post-treatment. Reductions in symptoms of depression and anxiety were assessed at baseline, post-intervention, and at 3-month follow-up. RESULTS: Approximately 60% of eligible participants were recruited. The study found high rates of programme completion (90%) and outcome data were obtained from 90% of participants. Improvement in symptoms of depression (and anxiety) were seen after treatment. Gains were maintained at 3-month follow-up. CONCLUSIONS: Guided transdiagnostic ICBT programme is a feasible and acceptable treatment option for those with psychological needs following SCI.
