Blending Internet-based and tele group treatment: Acceptability, effects, and mechanisms of change of cognitive behavioral treatment for depression

Effectiveness of a blended group transdiagnostic treatment for emotional disorders: Study protocol for a randomized controlled trial

Introduction

Emotional disorders (ED) (mood and anxiety disorders) are very prevalent and disabling, and often appear in comorbid presentations. Although there are effective treatments for these disorders, there is still a large gap between the number of people who need them and those who actually receive them. The combination of three strategies may help in this regard, facilitating the dissemination and accessibility of treatment: the transdiagnostic perspective of ED, the group format, and the use of technologies in a blended format (i.e., the combination of online and face-to-face therapy elements). This study intends to compare the efficacy of a new ED intervention, a transdiagnostic group treatment protocol administered in a blended format, with that of a face-to-face treatment. This article describes the study protocol for the randomized controlled trial.

Method and analyses

A two-arm, parallel-group, randomized controlled clinical trial (RCT) will be conducted. Participants (N = 144) will be adult volunteers suffering from DSM-5 anxiety and/or depressive disorders and will be randomly assigned to one of two conditions: Face-to-face Group Transdiagnostic Protocol or Blended Group Transdiagnostic Protocol. The face-to-face condition will consist of a total of 16 weekly face-to-face group sessions, while the blended condition will consist of 8 biweekly face-to-face group sessions in combination with self-applied work through a web platform. Clinical and acceptability measures will be included in both groups. Assessments will be performed at baseline, during the treatment, at post-treatment, and at 3-, 6- and 12-month follow-ups. This study received the approval of the Ethics Committee of Universitat Jaume I in October 2021 (CD/91/2021). Intention-to-treat analyses will be performed. Statistical analyses will be carried out using SPSS version 28.0. The results will be reported in accordance with CONSORT recommendations.

Discussion

This is the first RCT to compare the effectiveness of an ED treatment protocol based on the transdiagnostic perspective and applied in group and blended format. It will offer relevant data to continue moving forward towards treatment alternatives that are cost-effective and more accessible, so that all patients with ED who require them can benefit.

Clinical and cost-effectiveness of remote-delivered, online lifestyle therapy versus psychotherapy for reducing depression: results from the CALM non-inferiority, randomised trial

Background

We conducted the first non-inferiority, randomised controlled trial to determine whether lifestyle therapy is non-inferior to psychotherapy with respect to mental health outcomes and costs when delivered via online videoconferencing.

Methods

An individually randomised, group treatment design with computer-generated block randomisation was used. Between May 2021-April 2022, 182 adults with a Distress Questionnaire-5 score = ≥8 (indicative depression) were recruited from a tertiary mental health service in regional Victoria, Australia and surrounds. Participants were assigned to six 90-min sessions over 8-weeks using group-based, online videoconferencing comprising: (1) lifestyle therapy (targeting nutrition, physical activity) with a dietitian and exercise physiologist (n = 91) or (2) psychotherapy (Cognitive Behavioural Therapy) with psychologists (n = 91). The primary outcome was Patient Health Questionnaire-9 (PHQ-9) depression at 8-weeks (non-inferiority margin ≤2) using Generalised Estimating Equations (GEE). Cost-minimisation analysis estimated the mean difference in total costs from health sector and societal perspectives. Outcomes were assessed by blinded research assistants using Computer Assisted Telephone Interviews. Results are presented per-protocol (PP) and Intention to Treat (ITT) using beta coefficients with 95% Confidence Intervals (CIs).

Findings

The sample was 80% women (mean: 45-years [SD:13.4], mean PHQ-9:10.5 [SD:5.7]. An average 4.2 of 6 sessions were completed, with complete data for n = 132. Over 8-weeks, depression reduced in both arms (PP: Lifestyle (n = 70) mean difference:-3.97, 95% CIs:-5.10, -2.84; and Psychotherapy (n = 62): mean difference:-3.74, 95% CIs:-5.12, -2.37; ITT: Lifestyle (n = 91) mean difference:-4.42, 95% CIs: -4.59, -4.25; Psychotherapy (n = 91) mean difference:-3.82, 95% CIs:-4.05, -3.69) with evidence of non-inferiority (PP GEE β:-0.59; 95% CIs:-1.87, 0.70, n = 132; ITT GEE β:-0.49, 95% CIs:-1.73, 0.75, n = 182). Three serious adverse events were recorded. While lifestyle therapy was delivered at lower cost, there were no differences in total costs (health sector adjusted mean difference: PP AUD$156 [95% CIs -$182, $611, ITT AUD$190 [95% CIs -$155, $651] ]; societal adjusted mean difference: PP AUD$350 [95% CIs:-$222, $1152] ITT AUD$ 408 [95% CIs -$139, $1157].

Interpretation

Remote-delivered lifestyle therapy was non-inferior to psychotherapy with respect to clinical and cost outcomes. If replicated in a fully powered RCT, this approach could increase access to allied health professionals who, with adequate training and guidelines, can deliver mental healthcare at comparable cost to psychologists.

This trial was funded by the Australian Medical Research Future Fund (GA133346) under its Covid-19 Mental Health Research Grant Scheme.

A blended intervention for adjustment disorder: Study protocol for a feasibility trial

Introduction

Adjustment disorder (AjD) is a maladaptive response to one or more psychosocial stressors. In many cases, the symptomatology of this disorder disappears once the stressor or its consequences are no longer present. However, in some cases, if left untreated, the symptoms may worsen and develop into a more severe mental disorder. In this regard, different authors propose that a low-intensity intervention may be suitable for this disorder. Previous studies with other mental disorders and with patients with AjD found that blended interventions can be a viable and effective option. The aim of this study is to analyze the feasibility (the participants' expectations and preferences, the satisfaction and acceptance, the appropriateness of different methods of recruitment and data collection, and the reasons for dropping out) of a blended cognitive-behavioral intervention (CBT) for AjD that combines the use of a self-applied Internet-based program with videoconference sessions with a therapist. As a secondary objective, the potential efficacy of this intervention will be tested.

Method and analysis

A feasibility trial with a single-group and open-trial design will be conducted. A total of 41 participants will be assigned to the single treatment group. All the participants will be assessed for eligibility and respond at four measurement points: pre-treatment, post-treatment, and 3- and 12-month follow-ups. The treatment combines the use of an Internet-based intervention through a web platform with videoconference sessions with a therapist every 10-12 days. The intervention contains seven modules and is based on CBT. The main outcome measures are related to the feasibility of the intervention (adherence, treatment satisfaction and expectations, participants' opinions, preferences, therapeutic alliance, and usability). Clinical measures will also be assessed.

Discussion

To the best of our knowledge, this is the first study to test a blended intervention for AjD in the Spanish language. We expect this intervention to be feasible, and that a future Randomized Controlled Trial will be able to show its efficacy. Potential limitations include difficulties in recruiting the sample, failures in the computer systems, or a high dropout rate. Measures have been taken to try to reduce the impact of these limitations. This study received the approval of the Ethics committee of Universitat Jaume I in March 2022 (CD/42/2022).

Telerehabilitation solutions in patient pathways: An overview of systematic reviews

Background

Telerehabilitation (TR), a branch of telemedicine, provides remote therapeutic rehabilitation through telecommunication. Driven by technological advances and benefits like remote monitoring and patient education, it has grown since 1998. The Coronavirus Disease 2019 (COVID-19) pandemic highlighted its importance in maintaining healthcare access.

Research question

What is the efficacy of TR compared to in-person rehabilitation? Are the assessment tools effective? Is TR well-accepted, and are costs reduced?

Methods

A bibliographic search on Medline, Cochrane and Google Scholar focused on systematic reviews (SRs) from 2014 to Mai 2024, comparing TR or home-based rehabilitation with in person treatments for various conditions. Independent reviewers conducted initial screenings, resolving disagreements by a third reviewer. Joanna Briggs Institute Critical Appraisal Checklist was used to evaluate the quality of review. The data was synthesised narratively.

Results

The search identified 665 SRs. After selection, 228 SR were included. TR models include synchronous (real-time video interactions), asynchronous (independent sessions through digital platforms) and mixed methods. Regardless of the medical fields, the conclusions of the SRs consistently point to the equivalence of TR compared to in-person rehabilitation. Remote evaluations via digital tools were reliable and valid for various assessments. TR is cost effectiveness and well accepted.

Conclusions

TR is a viable alternative or complement to traditional rehabilitation, offering enhanced accessibility, reduced costs and improved results. Barriers include technical issues, training and concerns about lack of physical contact. Mixed methods could address these challenges.

The Role of Self-Compassion and Attributions in the Mental Health of Older Adolescents amid the COVID-19 Pandemic

This study aimed to examine the relationship among self-compassion, attributional styles, and mental health and their components in older adolescents in the context of the COVID-19 pandemic. The role of each component of self-compassion (self-kindness, common humanity, mindfulness, self-judgment, isolation, and over-identification) and attributions (globality, stability, self-worth, and negative consequences) in predicting mental health was also analyzed. There were 322 participants aged 18 to 22 that participated in an online survey. The participants filled out a form that consisted of sociodemographic questions, COVID-19-related questions, the Self-Compassion Scale, the Mental Health Continuum-short form-and the Cognitive Styles Questionnaire-very short form. The results indicated moderate levels of self-compassion, attributions, and mental health in participants. Furthermore, gender differences in self-compassion were confirmed, meaning that male participants had higher total levels of self-compassion, and certain differences were observed on attribution subscales, but not on well-being subscales. Self-compassion and mental health were found to be positively correlated with each other and negatively correlated with negative attributions. Of the four attributional components, stability and negative consequences were revealed to be significant negative predictors in the first step but lost their significance with the inclusion of self-compassion components in the second step of the analysis. Regarding the six components of self-compassion, self-kindness, recoded isolation, and common humanity were significant positive predictors in the second step of the analysis. COVID-19-related items did not show any significant intergroup differences. Our findings contribute to a better understanding of the relationship between positive mental health, self-compassion, and attributions in older adolescents so that they can be used as theoretical support for related interventions, especially during and after times of crisis, such as a pandemic.

Personalization strategies in digital mental health interventions: a systematic review and conceptual framework for depressive symptoms

Introduction

Personalization is a much-discussed approach to improve adherence and outcomes for Digital Mental Health interventions (DMHIs). Yet, major questions remain open, such as (1) what personalization is, (2) how prevalent it is in practice, and (3) what benefits it truly has.

Methods

We address this gap by performing a systematic literature review identifying all empirical studies on DMHIs targeting depressive symptoms in adults from 2015 to September 2022. The search in Pubmed, SCOPUS and Psycinfo led to the inclusion of 138 articles, describing 94 distinct DMHIs provided to an overall sample of approximately 24,300 individuals.

Results

Our investigation results in the conceptualization of personalization as purposefully designed variation between individuals in an intervention's therapeutic elements or its structure. We propose to further differentiate personalization by what is personalized (i.e., intervention content, content order, level of guidance or communication) and the underlying mechanism [i.e., user choice, provider choice, decision rules, and machine-learning (ML) based approaches]. Applying this concept, we identified personalization in 66% of the interventions for depressive symptoms, with personalized intervention content (32% of interventions) and communication with the user (30%) being particularly popular. Personalization via decision rules (48%) and user choice (36%) were the most used mechanisms, while the utilization of ML was rare (3%). Two-thirds of personalized interventions only tailored one dimension of the intervention.

Discussion

We conclude that future interventions could provide even more personalized experiences and especially benefit from using ML models. Finally, empirical evidence for personalization was scarce and inconclusive, making further evidence for the benefits of personalization highly needed.

Efficacy of nondrug interventions in perinatal depression: A meta-analysis

Perinatal depression causes significant harm to mothers and unborn infants. Nondrug intervention is a common and acceptable method for reducing perinatal depression in pregnant women; however, it lacks an evidence-based basis. This study aimed to evaluate the effectiveness of nondrug interventions, such as cognitive behavioral therapy (CBT), interpersonal psychotherapy (IPT), and yoga, in reducing perinatal depression. Randomized controlled trials (RCTs) of CBT, IPT, and yoga for improving perinatal depression were searched in the Cochrane Library, PubMed, Web of Science, Embase, ProQuest, ScienceDirect, ClinicalKey, Wanfang Data (Chinese database), and China Knowledge Resource Integrated Database. The retrieval time limit was set from the establishment of the database to December 2021. Twenty-one studies involving a total of 1981 participants were included.The present meta-analysis showed that CBT and IPT could effectively alleviate depressive symptoms in perinatal women, and the curative effect of IPT was better than that of CBT. There was no significant difference in the improvement effect of yoga on participants with depressive symptoms compared with that in the controls.This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO, CRD42022307675).

A Multisite Non-Inferiority Randomized Controlled Trial of the Efficacy of Cognitive-Behavior Therapy for Generalized Anxiety Disorder Delivered by Videoconference

Delivering psychotherapy by videoconference has been studied in a number of clinical trials, but no large controlled trial has involved generalized anxiety disorder (GAD). This multicenter randomized controlled non-inferiority trial was conducted to test if cognitive-behavior psychotherapy delivered by videoconference (VCP) is as effective as cognitive-behavior psychotherapy delivered face-to-face, using a strict margin of tolerance for non-inferiority. A total of 148 adults received a 15-session weekly manualized program. The treatment was based on the intolerance of uncertainty model of GAD. The impact of treatment was assessed using primary (GAD severity), secondary (worry, anxiety, and intolerance of uncertainty) and tertiary (general functioning) variables measured before and after treatment and at 6-month and 12-month follow-ups. Results showed that: (a) the treatment was effective; (b) VCP for GAD was statistically non-inferior to face-to-face psychotherapy on primary, secondary and tertiary measures at all assessment points; (c) change in intolerance of uncertainty significantly predicted change in the primary outcome measure over and above important clinical factors common to all psychotherapies (motivation, working alliance, perceived therapist competence, and client satisfaction). These findings support the use of VCP as a promising treatment option for adults with GAD. Clinical trial registry: ISRCTN#12662027.
