ABSTRACT: Objectives
To evaluate the efficacy of an Internet behavioral weight loss program; and determine if adding periodic in-person sessions to an Internet intervention improves outcomes.Methods
481 healthy overweight adults (28% minority) were randomized to one of 3 delivery methods of a behavioral weight loss program with weekly meetings: Internet (n=161), InPerson (n=158), or Hybrid (Internet+InPerson, n=162). Outcome variables were weight at baseline and 6 months and percent of subjects achieving a 5 and 7% weight loss. The study took place in two centers in Vermont and Arkansas from 2003 to 2008.Results
Conditions differed significantly in mean weight loss [8.0 (6.1) kg vs. 5.5 (5.6) kg vs. 6.0 (5.5) kg], for InPerson, Internet, and Hybrid respectively, p<0.01, n=462). Weight loss for InPerson was significantly greater than the Internet and Hybrid conditions (p<0.05). Although the proportion reaching a 5% weight loss did not differ, the proportion losing 7% did differ significantly (56.3% vs. 37.3% vs. 44.4% for InPerson, Internet, and Hybrid respectively, p<0.01).Conclusions
These results demonstrate that the Internet is a viable alternative to in-person treatment for the delivery and dissemination of a behavioral weight-control intervention. The addition of periodic in-person sessions did not improve outcomes.

Project description:In-person lifestyle interventions for obesity treatment yield significant improvements in depression. These improvements may be attributed to the excellent weight losses produced by in-person interventions. In contrast, Internet programs yield more modest weight losses, and their effect on depression is unknown. This study is the first to examine whether Internet-delivered obesity treatment impacts depressive symptoms.Participants (N = 136) were randomized to either a community campaign plus Internet behavioral weight loss (IBWL) or community campaign alone (Control). IBWL did not include online social support components. A measure of depressive symptoms was administered, and weight was objectively assessed.Of the total sample, 24% met the clinical cutoff for elevated depression risk at baseline. IBWL participants lost more weight during treatment (P = 0.005) and experienced significantly greater improvements in depressive symptoms (P = 0.02). Among participants who met the clinical cutoff for elevated risk for depression at baseline, those assigned to IBWL had greater improvements in depressive symptoms during treatment compared to Control (P = 0.033). Consequently, at post-treatment, a smaller percentage of IBWL participants were at elevated risk for depression.This study is the first to show that Internet-delivered obesity treatment improves depression risk and depressive symptoms in individuals with overweight or obesity.

Project description:Comprehensive Behavioral Intervention for Tics (CBIT) is considered a first-line therapy for tics. However, availability of CBIT is extremely limited due to a lack of qualified therapists. This study is a multicenter (n = 5), randomized, controlled, observer-blind trial including 161 adult patients with chronic tic disorders (CTD) to provide data on efficacy and safety of an internet-delivered, completely therapist-independent CBIT intervention (iCBIT Minddistrict®) in the treatment of tics compared to placebo and face-to-face (f2f) CBIT. Using a linear mixed model with the change to baseline of Yale Global Tic Severity Scale-Total Tic Score (YGTSS-TTS) as a dependent variable, we found a clear trend towards significance for superiority of iCBIT (n = 67) over placebo (n = 70) (-1.28 (-2.58; 0.01); p = 0.053). In addition, the difference in tic reduction between iCBIT and placebo increased, resulting in a significant difference 3 (-2.25 (-3.75; -0.75), p = 0.003) and 6 months (-2.71 (-4.27; -1.16), p < 0.001) after the end of treatment. Key secondary analysis indicated non-inferiority of iCBIT in comparison to f2f CBIT (n = 24). No safety signals were detected. Although the primary endpoint was narrowly missed, it is strongly suggested that iCBIT is superior compared to placebo. Remarkably, treatment effects of iCBIT even increased over time.

Project description:Internet-delivered cognitive-behavioral therapy (iCBT) is a promising treatment for chronic pain among youth, but effect sizes are small, and strategies aimed at enhancing treatment effects are needed. Participants' engagement with the program may be an important factor in determining treatment outcomes. The primary aim of the current study was to examine the relationship between treatment engagement and treatment outcomes. Secondarily, we sought to characterize participant engagement in an iCBT program for adolescents with chronic pain and their parents. Participants included 134 adolescents randomized to the intervention arm of a controlled trial examining iCBT for chronic pain. Overall engagement with the intervention by adolescents and parents was high. Parental engagement (number of modules completed by parents and number of parent logins) predicted adolescent activity limitations change scores at post-treatment. Contrary to our expectation, adolescent treatment engagement was not predictive of treatment outcomes. Results indicate that parental engagement with the program may be an important predictor of treatment outcomes. Further research is needed to better understand influences of treatment engagement on outcomes in iCBT for youth.

Project description:Background:Cognitive-behavioral therapy for insomnia (CBTi) is considered the standard treatment. The internet has proven to be a useful and successful tool of providing CBTi. However, few studies have investigated the possible effect of unguided internet-delivered CBTi (ICBTi) on comorbid psychological symptoms and fatigue. Methods:Based on a randomized controlled trial, we investigated whether unguided ICBTi had an effect on comorbid psychological symptoms. Adults with insomnia (n?=?181; 67% women; mean age 44.9?years [SD 13.0]) were randomized to ICBTi (n?=?95) or to an online patient education condition (n?=?86) for a nine-week period. Results:The results from mixed linear modelling yielded medium to large between-group effect sizes from pre- to post-treatment for symptoms of anxiety or depression (d?=?-0.57; 95% CI?=?0.79-0.35) and fatigue (d?=?0.92; 95% CI?=?1.22-0.62). The ICBTi group was reassessed at a 6-month non-randomized follow-up, and the completing participants had on the average a significant increase (from the post-assessment) on symptoms of anxiety or depression, while the reduction in symptoms of fatigue (on post-assessment) was maintained. However, due to high dropout attrition and no control group data, caution should be made regarding the long-term effects. In conclusion, the present findings show that unguided ICBTi positively influence comorbid symptoms in the short-term, thereby emphasizing the clinical relevance of unguided ICBTi.

Project description:BACKGROUND:Patient adherence is defined as the extent to which a patient complies with medical or health advice. At present, there is a lack of reliable and valid measures specifically designed to measure adherence to internet-delivered behavioral interventions. OBJECTIVE:The objective of this study was to develop and psychometrically evaluate a novel measure of adherence to guided internet-delivered behavioral interventions. METHODS:In collaboration with experienced clinicians and researchers in the field, a 5-item, clinician-rated internet intervention Patient Adherence Scale (iiPAS) was developed. The initial scale was tested in a sample of children and adolescents (N=50) participating in internet-delivered cognitive behavioral therapy (ICBT) studies. A revised version of the iiPAS was then administered to a larger sample of children and adolescents (N=148) with various behavioral problems participating in ICBT trials. The scale was evaluated according to a classical test theory framework. RESULTS:The iiPAS demonstrated excellent internal consistency. Factor analyses revealed one underlying factor, explaining about 80% of the variance, suggesting that the scale captures a homogeneous adherence construct. The iiPAS was strongly associated with objective measures of patient activity in ICBT (number of logins, number of written characters, and completed modules). Furthermore, mid- and posttreatment ratings of the iiPAS were significantly correlated with treatment outcomes. By contrast, objective measures of patient activity in the Web-based platform did not correlate with treatment outcomes. CONCLUSIONS:The iiPAS could be a useful tool to measure adherence in a broad range of internet-delivered behavioral interventions.

Project description:BackgroundStudies on guided internet-delivered treatment have demonstrated promising results for patients with depressive disorder.ObjectiveThe aim of this study was to provide an overview of this research area and identify potential gaps in the research.MethodsIn this scoping review, web-based databases were used to identify research papers published between 2010 and 2022 where guided internet-delivered treatment was administered to participants with depressive disorders, a standardized rating scale of depressive symptoms was used as the primary outcome measure, and the treatment was compared with a control condition.ResultsA total of 111 studies were included, and an overview of the studies was provided. Several gaps in the research were identified regarding the design of the studies, treatments delivered, participant representation, and treatment completion.ConclusionsThis review provides a comprehensive overview of the research area, and several research gaps were identified. The use of other designs and active control conditions is recommended. Future studies should provide access to treatment manuals, and more replications should be conducted. Researchers should aim to include underrepresented populations and provide reports of comorbidities. Definitions of adequate dosage, reports of completion rates, and reasons for treatment dropout are recommended for future studies.

Project description:ImportanceSocial anxiety disorder (SAD) is a prevalent childhood-onset disorder associated with lifelong adversity and high costs for the individual and society at large. Cognitive behavioral therapy (CBT) is an established evidence-based treatment for SAD, but its availability is limited.ObjectiveTo assess the efficacy and cost-effectiveness of therapist-guided internet-delivered cognitive behavioral therapy (ICBT) for SAD in youths vs an active comparator, internet-delivered supportive therapy (ISUPPORT).Design, setting, and participantsThis single-masked, superiority randomized clinical trial enrolled participants at a clinical research unit integrated within the child and adolescent mental health services in Stockholm, Sweden, from September 1, 2017, to October 31, 2018. The final participant reached the 3-month follow-up (primary end point) in May 2019. Children and adolescents 10 to 17 years of age with a principal diagnosis of SAD and their parents were included in the study.InterventionsICBT and ISUPPORT, both including 10 online modules, 5 separate parental modules, and 3 video call sessions with a therapist.Main outcomes and measuresThe Clinician Severity Rating (CSR), derived from the Anxiety Disorder Interview Schedule, rated by masked assessors 3 months after the end of treatment. The CSR ranges from 0 to 8, with scores of 4 or higher indicating caseness. Secondary outcomes included masked assessor-rated diagnostic status of SAD and global functioning, child- and parent-reported social anxiety and depressive symptoms, and health-related costs.ResultsOf the 307 youths assessed for eligibility, 103 were randomized to 10 weeks of therapist-guided ICBT (n = 51) or therapist-guided ISUPPORT (n = 52) for SAD. The sample consisted of 103 youths (mean [SD] age, 14.1 [2.1] years; 79 [77%] female). Internet-delivered cognitive behavioral therapy was significantly more efficacious than ISUPPORT in reducing the severity of SAD symptoms. Mean (SD) CSR scores for ICBT at baseline and at the 3-month follow-up were 5.06 (0.95) and 3.96 (1.46), respectively, compared with 4.94 (0.94) and 4.48 (1.30) for ISUPPORT. There was a significant between-group effect size of d = 0.67 (95% CI, 0.21-1.12) at the 3-month follow-up. Similarly, all of the secondary outcome measures demonstrated significant differences with small to large effect sizes, except for child-rated quality of life (nonsignificant). The cost-effectiveness analyses indicated cost savings associated with ICBT compared with ISUPPORT, with the main drivers of the savings being lower medication costs (z = 2.38, P = .02) and increased school productivity (z = 1.99, P = .047) in the ICBT group. There was 1 suicide attempt in the ISUPPORT group; no other serious adverse events occurred in either group.Conclusions and relevanceIn this randomized clinical trial, internet-delivered cognitive behavioral therapy was an efficacious and cost-effective intervention for children and adolescents with SAD. Implementation in clinical practice could markedly increase the availability of effective interventions for SAD.Trial registrationClinicalTrials.gov Identifier: NCT03247075.

Project description:ObjectiveIntensive behavioral obesity treatments face scalability challenges, but evidence is lacking about which treatment components could be cut back without reducing weight loss. The Optimization of Remotely Delivered Intensive Lifestyle Treatment for Obesity (Opt-IN) study applied the Multiphase Optimization Strategy to develop an entirely remotely delivered, technology-supported weight-loss package to maximize the amount of weight loss attainable for ≤$500.MethodsSix-month weight loss was examined among adults (N = 562) with BMI ≥ 25 who were randomly assigned to conditions in a factorial experiment crossing five dichotomous treatment components set to either low/high (12 vs. 24 coaching calls) or off/on (primary care provider reports, text messaging, meal replacements, and buddy training).ResultsAbout 84.3% of participants completed the final assessment. The treatment package yielding maximum weight loss for ≤$500 included 12 coaching calls, buddy training, and primary care provider progress reports; produced average weight loss of 6.1 kg, with 57.1% losing ≥5% and 51.8% losing ≥7%; and cost $427 per person. The most expensive candidate-treatment component (24 vs. 12 coaching calls) was screened out of the optimized treatment package because it did not increase weight loss.ConclusionsSystematically testing each treatment component's effect on weight loss made it possible to eliminate more expensive but less impactful components, yielding an optimized, resource-efficient obesity treatment for evaluation in a randomized controlled trial.

Project description:BackgroundInternet-delivered psychological treatments (IDPTs) are built on evidence-based psychological treatment models, such as cognitive behavioral therapy, and are adjusted for internet use. The use of internet technologies has the potential to increase access to evidence-based mental health services for a larger proportion of the population with the use of fewer resources. However, despite extensive evidence that internet interventions can be effective in the treatment of mental health disorders, user adherence to such internet intervention is suboptimal.ObjectiveThis review aimed to (1) inspect and identify the adaptive elements of IDPT for mental health disorders, (2) examine how system adaptation influences the efficacy of IDPT on mental health treatments, (3) identify the information architecture, adaptive dimensions, and strategies for implementing these interventions for mental illness, and (4) use the findings to create a conceptual framework that provides better user adherence and adaptiveness in IDPT for mental health issues.MethodsThe review followed the guidelines from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The research databases Medline (PubMed), ACM Digital Library, PsycINFO, CINAHL, and Cochrane were searched for studies dating from January 2000 to January 2020. Based on predetermined selection criteria, data from eligible studies were analyzed.ResultsA total of 3341 studies were initially identified based on the inclusion criteria. Following a review of the title, abstract, and full text, 31 studies that fulfilled the inclusion criteria were selected, most of which described attempts to tailor interventions for mental health disorders. The most common adaptive elements were feedback messages to patients from therapists and intervention content. However, how these elements contribute to the efficacy of IDPT in mental health were not reported. The most common information architecture used by studies was tunnel-based, although a number of studies did not report the choice of information architecture used. Rule-based strategies were the most common adaptive strategies used by these studies. All of the studies were broadly grouped into two adaptive dimensions based on user preferences or using performance measures, such as psychometric tests.ConclusionsSeveral studies suggest that adaptive IDPT has the potential to enhance intervention outcomes and increase user adherence. There is a lack of studies reporting design elements, adaptive elements, and adaptive strategies in IDPT systems. Hence, focused research on adaptive IDPT systems and clinical trials to assess their effectiveness are needed.

Project description:BackgroundInsomnia is of major public health importance. While cognitive behavioral therapy is beneficial, in-person treatment is often unavailable. We assessed the effectiveness of internet-delivered cognitive behavioral therapy for insomnia.ObjectivesThe primary objectives were to determine whether online cognitive behavioral therapy for insomnia could improve sleep efficiency and reduce the severity of insomnia in adults. Secondary outcomes included sleep quality, total sleep time, time in bed, sleep onset latency, wake time after sleep onset, and number of nocturnal awakenings.Data sourcesWe searched PubMed/MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, PsycInfo, Cochrane Library, Embase, and the Web of Science for randomized trials.MethodsStudies were eligible if they were randomized controlled trials in adults that reported application of cognitive behavioral therapy for insomnia via internet delivery. Mean differences in improvement in sleep measures were calculated using the Hartung-Knapp-Sidik-Jonkman method for random effects meta-analysis.ResultsWe found 15 trials, all utilizing a pretest-posttest randomized control group design. Sleep efficiency was 72% at baseline and improved by 7.2% (95% CI: 5.1%, 9.3%; p<0.001) with internet-delivered cognitive behavioral therapy versus control. Internet-delivered cognitive behavioral therapy resulted in a decrease in the insomnia severity index by 4.3 points (95% CI: -7.1, -1.5; p = 0.017) compared to control. Total sleep time averaged 5.7 hours at baseline and increased by 20 minutes with internet-delivered therapy versus control (95% CI: 9, 31; p = 0.004). The severity of depression decreased by 2.3 points (95% CI: -2.9, -1.7; p = 0.013) in individuals who received internet-delivered cognitive behavioral therapy compared to control. Improvements in sleep efficiency, the insomnia severity index and depression scores with internet-delivered cognitive behavioral therapy were maintained from 4 to 48 weeks after post-treatment assessment. There were no statistically significant differences between sleep efficiency, total sleep time, and insomnia severity index for internet-delivered versus in-person therapy with a trained therapist.ConclusionIn conclusion, internet-delivered cognitive behavioral therapy is effective in improving sleep in adults with insomnia. Efforts should be made to educate the public and expand access to this therapy. Registration Number, Prospero: CRD42015017622.
