- Description: There is preliminary support for internet-delivered cognitive behaviour therapy (iCBT) as a way of improving access to treatment among older adults with anxiety. The aim of this randomized controlled trial (RCT) was to examine the efficacy, long-term outcomes, and cost-effectiveness of an iCBT program for adults over 60. years of age with anxiety. Successful applicants were randomly allocated to either the treatment group (n= 35) or the waitlist control group (n= 37). The online treatment course was delivered over 8. weeks and provided with brief weekly contact with a clinical psychologist via telephone or secure email. Eighty-four percent of participants completed the iCBT course within the 8. weeks and 90% provided data at posttreatment. Significantly lower scores on measures of anxiety (Cohen's d=. 1.43; 95% CI: 0.89 - 1.93) and depression (Cohen's d=. 1.79; 95% CI: 1.21 - 2.32) were found among the treatment group compared to the control group at posttreatment. These lower scores were maintained at 3-month and 12-month follow-up and the treatment group rated the iCBT treatment as acceptable. The treatment group had slightly higher costs ($92.2; 95% CI: $38.7 to $149.2) and Quality-Adjusted Life-Years (QALYs. =. 0.010; 95% CI: 0.003 to 0.018) than the control group at posttreatment and the intervention was found to have a greater than 95% probability of being cost-effective. The results support iCBT as an efficacious and cost-effective treatment option for older adults with symptoms of anxiety. © 2014 Association for Behavioral and Cognitive Therapies.

- Description: Self-guided internet-delivered cognitive behavior therapy (iCBT) has considerable public health potential for treating anxiety and depression. However, no research has examined the use of self-guided iCBT, that is, treatment without contact with a clinician, specifically for older adults. The aim of the present study was to undertake a preliminary examination of the acceptability, efficacy and health economic impact of two entirely self-guided iCBT programs for adults over 60. years of age with anxiety and depression. Two separate single-group feasibility open trials of self-guided iCBT were conducted, the Anxiety Trial (n. =. 27) and the Depression Trial (n. =. 20), using the control groups of two randomized controlled trials. The online treatment packages consisted of five online educational lessons, which were delivered over 8. weeks without clinical contact. Participants rated the interventions as acceptable with more than 90% reporting the course was worth their time and more than 70% of participants completing at least 3 of the 5 lessons within the eight weeks. Significant reductions on measures of anxiety (Generalized Anxiety Disorder 7-item; GAD-7) and depression (Patient Health Questionnaire 9-item; PHQ-9) were observed from pre-treatment to post-treatment in both the Anxiety Trial (GAD-7 Cohen's d=. 1.17; 95% CI: 0.55 to 1.75) and the Depression Trial (PHQ-9 Cohen's d=. 1.06; 95% CI: 0.33 to 1.73). The economic analyses indicated that there was statistically significant improvement in health-related quality of life compared to baseline and marginally higher costs associated with treatment for both the Anxiety Trial ($69.84; 95% CI: $4.24 to $135.45) and the Depression Trial ($54.98; 95% CI: $3.84 to $106.12). The results provide preliminary support for the potential of entirely self-guided iCBT for older adults with anxiety and depression and indicate larger scale and controlled research trials are warranted.

- Description: Background: Cognitive behaviour therapy for insomnia (CBT-I) is a well-established treatment; however, the evidence is largely limited to homogenous samples. Although emerging research has indicated that CBT-I is also effective for comorbid insomnia, CBT-I has not been tested among a complex sample of older adults with comorbid insomnia and depression. Furthermore, no study has explored whether modifying CBT-I to target associated depressive symptoms could potentially enhance sleep and mood outcomes. Therefore, this study aims to report a protocol designed to test whether an advanced form of CBT for insomnia and depression (CBT-I-D) is more effective at reducing insomnia and depressive symptoms compared to a standard CBT-I and psychoeducation control group (PCG) for older adults in a community mental health setting. Methods/Design: We aim to recruit 150 older adults with comorbid insomnia who have presented to community mental health services for depression. Eligible participants will be randomly allocated via block/cluster randomisation to one of three group therapy conditions: CBT-I, CBT-I-D, or PCG. Participants who receive CBT-I will only practice strategies designed to improve their sleep, whereas participants who receive CBT-I-D will practice additional strategies designed to also improve their mood. This trial will implement a mixed-methods design involving quantitative outcome measures and qualitative focus groups. The primary outcome measures are insomnia and depression severity, and secondary outcomes are anxiety, hopelessness, beliefs about sleep, comorbid sleep conditions, and health. Outcomes will be assessed at pre-intervention (week 0), post-intervention (week 8), and 3-month follow-up (week 20). Discussion: This CBT study protocol has been designed to address comorbid insomnia and depression for older adults receiving community mental health services. The proposed trial will determine whether CBT-I is more effective for older adults with comorbid insomnia and depression compared to a PCG. It will also establish whether an advanced form of CBT-I-D generates greater reductions in insomnia and depression severity compared to standard CBT-I. The results from the proposed trial are anticipated to have important clinical implications for older adults, researchers, therapists, and community mental health services.

- Description: OBJECTIVE: The MindSpot Clinic provides online mental health services to Australian adults with anxiety and depression. This paper describes users of MindSpot between January 2013 and June 2015. Outcomes are considered against three key objectives: improving access to mental health services, improving public awareness of how to access services and providing evidence-based treatments. METHOD: Website traffic data were examined to determine patterns of use. Demographic characteristics, past service utilisation and reasons for contacting MindSpot were analysed. Outcomes for patients enrolled in a MindSpot treatment course were also analysed. Primary outcomes were scores on the 9-Item Patient Health Questionnaire, Generalised Anxiety Disorder 7-Item, Yale-Brown Obsessive Compulsive Scale and Post-Traumatic Stress Disorder Checklist-Civilian Version, administered at assessment, post-treatment and 3-month follow-up. RESULTS: The website was visited by almost 500,000 Australians, of which 33,990 adults started assessments, and 25,469 people completed assessment and were eligible for analysis. Mean age was 36.4 years (standard deviation = 13.3 years; range = 18-94 years), and 72% were female. The proportion living in rural or remote regions and who identified as Aboriginal and Torres Strait Islander closely matched national statistics. The majority (82%) reported that they were not currently in contact with mental health services. Most patients sought an assessment, information about treatment options, or referral to another service, and only 24% of those completing an assessment commenced a MindSpot treatment course. Of these, large clinical effects (d: 0.7-2.4; average symptom reductions: 25.5% to 61.6%) were found from assessment to follow-up on all outcome measures. Deterioration ranged from 1.0% to 4.3%. CONCLUSION: Based on the number of website visits, completed assessments and treatment outcomes, MindSpot achieved its three programme objectives. This model of service provision has considerable value as a complement to existing services, and is proving particularly important for improving access for people not using existing services.

- Description: Background: Internet-based assessment has the potential to assist with the diagnosis of mental health disorders and overcome the barriers associated with traditional services (eg, cost, stigma, distance). Further to existing online screening programs available, there is an opportunity to deliver more comprehensive and accurate diagnostic tools to supplement the assessment and treatment of mental health disorders. Objective: The aim was to evaluate the diagnostic criterion validity and test-retest reliability of the electronic Psychological Assessment System (e-PASS), an online, self-report, multidisorder, clinical assessment and referral system. Methods: Participants were 616 adults residing in Australia, recruited online, and representing prospective e-PASS users. Following e-PASS completion, 158 participants underwent a telephone-administered structured clinical interview and 39 participants repeated the e-PASS within 25 days of initial completion. Results: With structured clinical interview results serving as the gold standard, diagnostic agreement with the e-PASS varied considerably from fair (eg, generalized anxiety disorder:kappa=.37) to strong (eg, panic disorder:kappa=.62). Although the e-PASS' sensitivity also varied (0.43-0.86) the specificity was generally high (0.68-1.00). The e-PASS sensitivity generally improved when reducing the e-PASS threshold to a subclinical result. Test-retest reliability ranged from moderate (eg, specific phobia:kappa=.54) to substantial (eg, bulimia nervosa:kappa=.87). Conclusions: The e-PASS produces reliable diagnostic results and performs generally well in excluding mental disorders, although at the expense of sensitivity. For screening purposes, the e-PASS subclinical result generally appears better than a clinical result as a diagnostic indicator. Further development and evaluation is needed to support the use of online diagnostic assessment programs for mental disorders.

- Description: e-TC is an online intervention designed to address common psychosocial concerns of testicular cancer survivors. It aims to reduce anxiety, depression and fear of cancer recurrence by providing evidence-based information and psychological intervention. This paper details the development and pilot testing of e-TC. During pilot testing, 25 men (with varying psychological profiles) who had completed treatment for testicular cancer, 6 months to 5 years ago (which had not recurred), used e-TC over a 10-week period and provided quantitative and qualitative feedback on the feasibility and acceptability of the programme. Six men also completed a qualitative interview to provide detailed feedback on their experiences using e-TC. Fourteen men (56%) completed at least 80% of the programme. Participants reported a high level of satisfaction with the programme. Men's limited time was a barrier to programme use and completion, and participants suggested that men with a more recent diagnosis and a higher level of distress may be more likely to engage with the programme. e-TC appears to be a feasible and acceptable online intervention for survivors of testicular cancer. Findings from this study are currently being used to refine e-TC and guide the design of a larger efficacy study. © 2017 John Wiley & Sons Ltd

- Description: Information and communication technologies are increasingly being used to remotely deliver psychological services. This delivery method confers clear advantages to both client and therapist, including the accessibility of services by otherwise unserved populations and cost-effective treatment. Remote services can be delivered in a real-time or delayed manner, providing clients with a wealth of therapy options not previously available. The proliferation of these services has outstripped the development and implementation of all but the most rudimentary of regulatory frameworks, potentially exposing clients to substandard psychological services. Integrating mandatory training on the delivery of online psychological services into accredited postgraduate psychology courses would aid in addressing this issue. The purpose of this article is to outline issues of consideration in the development and implementation of such a training programme. An online etherapy training programme developed by Swinburne University's National eTherapy Centre will be used as an example throughout.

- Description: Background: Mental illness is an escalating concern worldwide. The management of disorders such as anxiety and depression largely falls to family doctors or general practitioners (GPs). However, GPs are often too time constrained and may lack the necessary training to adequately manage the needs of such patients. Evidence-based Internet interventions represent a potentially valuable resource to reduce the burden of care and the cost of managing mental health disorders within primary care settings and, at the same time, improve patient outcomes. Objective: The present study sought to extend the efficacy of a therapist-assisted Internet treatment program for panic disorder, Panic Online, by determining whether comparable outcomes could be achieved and maintained when Panic Online was supported by either GPs or psychologists. Methods: Via a natural groups design, 96 people with a primary diagnosis of panic disorder (with or without agoraphobia) completed the Panic Online program over 12 weeks with the therapeutic assistance of their GP (n = 53), who had received specialist training in cognitive behavioral therapy, or a clinical psychologist (n = 43). Participants completed a clinical diagnostic telephone interview, conducted by a psychologist, and a set of online questionnaires to assess panic-related symptoms at three time periods (pretreatment, posttreatment, and 6 month follow-up). Results: Both treatments led to clinically significant improvements on measures of panic and panic-related symptomatology from pretreatment to posttreatment. Both groups were shown to significantly improve over time. Improvements for both groups were maintained at follow-up; however, the groups did differ significantly on two quality of life domains: physical (F1,82 = 9.13, P = .00) and environmental (F1,82 = 4.41, P = .04). The attrition rate was significantly higher among those being treated by their GP (χ 2 1 = 4.40, P = .02, N = 96). Conclusions: This study provides evidence that Internet-based interventions are an effective adjunct to existing mental health care systems. Consequently, this may facilitate and enhance the delivery of evidence-based mental health treatments to increasingly large segments of the population via primary care systems and through suitably trained health professionals.

- Description: There is considerable research suggesting that therapist-assisted Internet cognitive behaviour therapy (ICBT) is efficacious in the treatment of depression and anxiety. Given this research, there is a growing interest in training students in therapist-assisted ICBT in order to assist with the dissemination of this emerging modality into routine clinical practice. In this study, we developed, delivered, and evaluated a therapist-assisted ICBT workshop for clinical psychology graduate students (n = 20). The workshop provided both research evidence and practical information related to the delivery of therapist-assisted ICBT. The workshop also incorporated an experiential component with students working on and discussing responses to client e-mails. Before and after the workshop, we measured knowledge of therapist-assisted ICBT research and professional practice issues, as well as attitudes towards and confidence in delivering therapist-assisted ICBT. Statistically significant changes were observed in all areas. Eighty-five per cent of students are now offering therapist-assisted ICBT under supervision. We conclude by discussing future research directions related to disseminating therapist-assisted ICBT. © 2012 Copyright Swedish Association for Behaviour Therapy.

- Description: Background: Anxiety and depression are leading causes of disease worldwide, requiring timely access to evidence-based treatment. Digital mental health (dMH) interventions increase accessibility to evidence-based psychological services delivered in a variety of web-based formats (eg, self-help and therapist-assisted interventions). Robust and rigorous studies of adaptive web-based intervention designs are scarce. No identified randomized clinical trial has investigated the efficacy of a 2-stage adaptive design, whereby the program-only condition or no support dMH treatment program is augmented by either low or high therapist assistance, if a participant does not improve or engage in the program-only condition. Objective: The primary objective is to assess whether low or high therapist-assisted support delivered via video chat is more effective in reducing anxiety and depressive symptoms compared with a dMH program–only condition. The secondary objective is to evaluate the role of motivation; self-efficacy; and preferences in participant engagement, adherence, and clinical outcomes (anxiety and depression symptoms) among the 3 treatment conditions (program only, low-intensity therapist assistance, and high-intensity therapist assistance). A mixed methods analysis of factors affecting participant attrition, participant reasons for nonengagement and withdrawal, and therapist training and implementation of dMH interventions will be completed. Qualitative data regarding participant and therapist experiences and satisfaction with video chat assessment and treatment will also be analyzed. Methods: Australian adults (N=137) with symptoms or a diagnosis of anxiety or depression will be screened for eligibility and given access to the 8-module Life Flex dMH treatment program. On day 15, participants who meet the augmentation criteria will be stepped up via block randomization to receive therapist assistance delivered via video chat for either 10 minutes (low intensity) or 50 minutes (high intensity) per week. This adaptive trial will implement a mixed methods design, with outcomes assessed before the intervention (week 0), during the intervention (weeks 3 and 6), after the intervention (week 9), and at the 3-month follow-up (week 21). Results: The primary outcome measures are for anxiety (Generalized Anxiety Disorder–7) and depression severity (Patient Health Questionnaire–9). Measures of working alliance, health status, health resources, preferences, self-efficacy, and motivation will be used for secondary outcomes. Qualitative methods will be used to explore participant and therapist experiences of video chat assessment and treatment, participant reasons for withdrawal and nonengagement, and therapist training and implementation experiences. Data collection commenced in November 2020 and was completed at the end of March 2022. Conclusions: This is the first mixed methods adaptive trial to explore the comparative efficacy of different intensity levels of self-help and a therapist-assisted dMH intervention program delivered via video chat for adults with anxiety or depression. Anticipated results may have implications for the implementation of dMH interventions. © Brooke Andrews, Britt Klein, Suzanne McLaren, Shaun Watson, Denise Corboy.

- Description: Background: Anxiety disorders and depression are prevalent disorders with high comorbidity, leading to greater chronicity and severity of symptoms. Given the accessibility to treatment issues, more evaluation is needed to assess the potential benefits of fully automated self-help transdiagnostic digital interventions. Innovating beyond the current transdiagnostic one-size-fits-all shared mechanistic approach may also lead to further improvements. Objective: The primary objective of this study was to explore the preliminary effectiveness and acceptability of a new fully automated self-help biopsychosocial transdiagnostic digital intervention (Life Flex) aimed at treating anxiety and/or depression, as well as improving emotional regulation; emotional, social, and psychological well-being; optimism; and health-related quality of life. Methods: This was a real-world pre-during-post-follow-up feasibility trial design evaluation of Life Flex. Participants were assessed at the preintervention time point (week 0), during intervention (weeks 3 and 5), at the postintervention time point (week 8), and at 1- and 3-month follow-ups (weeks 12 and 20, respectively). Results: The results provided early support for the Life Flex program in reducing anxiety (Generalized Anxiety Disorder 7), depression (Patient Health Questionnaire 9), psychological distress (Kessler 6), and emotional dysregulation (Difficulties in Emotional Regulation 36) and increasing emotional, social, and psychological well-being (Mental Health Continuum-Short Form); optimism (Revised Life Orientation Test); and health-related quality of life (EQ-5D-3L Utility Index and Health Rating; all false discovery rate [FDR] < .001).

- Description: Background: Digital mental health (DMH) interventions incorporating elements that adapt to the evolving needs of consumers have the potential to further our understanding of the optimal intensity of therapist assistance and inform stepped-care models. Objective: The primary objective was to compare the efficacy of a transdiagnostic biopsychosocial DMH program, with or without therapist assistance for adults with subthreshold symptoms or a diagnosis of anxiety or depression. Methods: In a randomized adaptive clinical trial design, all participants had access to the DMH program, with eligibility to have their program augmented with therapist assistance determined by program engagement or symptom severity. Participants who met stepped-care criteria were randomized to have their treatment program augmented with either low-intensity (10 min/week of video chat support for 7 weeks) or high-intensity (50 min/week of video chat support for 7 weeks) therapist assistance. A total of 103 participants (mean age 34.17, SD 10.50 years) were assessed before (week 0), during (weeks 3 and 6), and after the intervention (week 9) and at the 3-month follow-up (week 21). The effects of 3 treatment conditions (DMH program only, DMH program+low-intensity therapist assistance, and DMH program+high-intensity therapist assistance) on changes in the 2 primary outcomes of anxiety (7-item Generalized Anxiety Disorder Scale [GAD-7]) and depression (9-item Patient Health Questionnaire [PHQ-9]) were assessed using the Cohen d, reliable change index, and mixed-effects linear regression analyses. Results: There were no substantial differences in the outcome measures among intervention conditions. However, there were significant time effect changes in most outcomes over time. All 3 intervention conditions demonstrated strong and significant treatment effect changes in GAD-7 and PHQ-9 scores, with absolute Cohen d values ranging from 0.82 to 1.79 (all P<.05). The mixed-effects models revealed that, in the Life Flex program–only condition at week 3, mean GAD-7 and PHQ-9 scores significantly decreased from baseline by 3.54 and 4.38 (all P<.001), respectively. At weeks 6, 9, and 21, GAD-7 and PHQ-9 scores significantly decreased from baseline by at least 6 and 7 points (all P<.001), respectively. Nonresponders at week 3 who were stepped up to therapist assistance increased program engagement and treatment response. At the postintervention time point and 3-month follow-up, 67% (44/65) and 69% (34/49) of the participants, respectively, no longer met diagnostic criteria for anxiety or depression. Conclusions: The findings highlight that early detection of low engagement and non–treatment response presents an opportunity to effectively intervene by incorporating an adaptive design. Although the study findings indicate that therapist assistance was no more effective than the DMH intervention program alone for reducing symptoms of anxiety or depression, the data highlight the potential influence of participant selection bias and participant preferences within stepped-care treatment models. ©Brooke Andrews, Britt Klein, Huy Van Nguyen, Denise Corboy, Suzanne McLaren, Shaun Watson.

- Description: The purpose of this article is to qualitatively explore participant and therapist experiences of the therapeutic alliance, perceived benefits, challenges, and areas for improvement when using video chat as a mode of therapist assistance within an adaptive digital mental health intervention. In total, 74 semistructured interviews were completed with participants and therapists who participated in an adaptive clinical trial. The participant interviews explored experiences of attending a clinical assessment via video chat and experiences of receiving low- or high-intensity therapist assistance via video chat. Interviews completed with therapists explored their experience of administrating a clinical assessment tool and delivering therapist assistance, both via video chat. Reflexive thematic analysis identified four themes: using video chat, characteristics of therapeutic relationships, task-specific experiences, and utility and adoption of video chat. Both participants and therapists were able to adapt to the modality of video chat and develop positive therapeutic alliances. They reported satisfaction with video chat for conducting clinical assessments and delivering therapist assistance. Concerns were identified by both participants and therapists with low-intensity therapist assistance. This study identified elements of task-specific experiences and human characteristics as more influential in participant and therapist experience than the modality of video chat technology. Implications for assessing suitability for the modality of video chat and low- and high-intensity models of therapist assistance are discussed.
