Effects of telehealth interventions for adolescent sexual health: A systematic review and meta-analysis of randomized controlled studies

INTRODUCTION

Telehealth interventions to advance adolescent sexual health have evolved and are being used to promote adolescent sexual health knowledge and healthy sexual behaviors. However, as this area of intervention modality expands, there is a need to pause and examine the effects of telehealth interventions on adolescent sexual health outcomes. Addressing this knowledge gap will inform researchers and practitioners on the current state of evidence of telehealth interventions and inform further intervention development and testing. This study aimed to explore the meta-effects of telehealth interventions on self-efficacy of using condoms, condom use practices, and sexually transmitted infection testing behaviors among adolescents.

METHODS

A systematic review and meta-analysis of randomized controlled trials were conducted. Seven databases (Academic Search Complete, CINAHL, EMBASE, MEDLINE, PubMed, OVID (UpToDate), and Web of Science) were searched for relevant full-text articles from the inception to May 2021. The revised Cochrane risk-of-bias tool for randomized trials was used to assess the methodological quality of the included studies. A meta-analysis was performed using a random effects model to calculate the pooled effects of telehealth interventions for adolescents. Stata 16.0 was used for statistical analysis.

RESULTS

A total of 15 studies (N = 5499) that used telehealth interventions with adolescents were included in the analysis. Telehealth interventions were found to increase self-efficacy for condom use (standardized mean difference: 0.22; 95% confidence interval: 0.08-0.36), practice for condom use (standardized mean difference: 0.35; 95% confidence interval: 0.23-0.47), and being screened/tested for sexual transmitted infections (standardized mean difference: 0.61; 95% confidence interval: 0.31-0.92).

DISCUSSION

Telehealth interventions show promise as effective intervention delivery solutions for improving self-efficacy and certain sexual health behaviors among adolescents. These telehealth strategies could be important alternatives to in-person visits to accessing sexual health information or services near where they live. Future research should consider testing telehealth strategies where there is evidence of impact to move the field forward.

Increasing Condom Use and STI Testing: Creating a Behaviourally Informed Sexual Healthcare Campaign Using the COM-B Model of Behaviour Change

Sexually transmitted infections (STIs) are a major public health challenge. Although theoretically informed public health campaigns are more effective for changing behaviour, there is little evidence of their use when campaigns are commissioned to the commercial sector. This study describes the implementation of the COM-B model to a sexual health campaign that brought together expertise from academics, sexual healthcare, and marketing and creative professionals. Insights were gathered following a review of the relevant academic literature. Barriers and facilitators to condom use and STI testing were explored with the use of the COM-B model and the Behaviour Change Wheel in a workshop attended by academics, behavioural scientists, healthcare experts and creative designers. Feedback on the creative execution of the campaign was obtained from healthcare experts and via surveys. Barriers to psychological capability, automatic and reflective motivation, and social opportunity were identified as targets for the campaign, and creative solutions to these barriers were collaboratively devised. The final sexual health campaign was rated positively in its ability to change attitudes and intentions regarding the use of condoms and STI testing. This study describes the implementation of the COM-B model of behaviour change to a public sexual health campaign that brought together academics, public and commercial sector expertise. The barriers and facilitators identified in this collaborative process represent potential targets for future public health communication campaigns.

Digital Health Promotion and Prevention in Settings: Scoping Review

BACKGROUND

Digital technologies are increasingly integrating into people's daily living environments such as schools, sport clubs, and health care facilities. These settings play a crucial role for health promotion and prevention because they affect the health of their members, as the World Health Organization has declared. Implementing digital health promotion and prevention in settings offers the opportunity to reach specific target groups, lower the costs of implementation, and improve the health of the population. Currently, there is a lack of scientific evidence that reviews the research on digital health promotion and prevention in settings.

OBJECTIVE

This scoping review aims to provide an overview of research targeting digital health promotion and primary prevention in settings. It assesses the range of scientific literature regarding outcomes such as applied technology, targeted setting, and area of health promotion or prevention, as well as identifies research gaps.

METHODS

The scoping review was conducted following the Levac, Colquhoun, and O'Brien framework. We searched scientific databases and gray literature for articles on digital setting-based health promotion and prevention published from 2010 to January 2020. We included empirical and nonempirical publications in English or German and excluded secondary or tertiary prevention and health promotion at the workplace.

RESULTS

From 8888 records, the search resulted in 200 (2.25%) included publications. We identified a huge diversity of literature regarding digital setting-based health promotion and prevention. The variety of technology types extends from computer- and web-based programs to mobile devices (eg, smartphone apps) and telemonitoring devices (sensors). We found analog, digital, and blended settings in which digital health promotion and prevention takes place. The most frequent analog settings were schools (39/200, 19.5%) and neighborhoods or communities (24/200, 12%). Social media apps were also included because in some studies they were defined as a (digital) setting. They accounted for 31.5% (63/200) of the identified settings. The most commonly focused areas of health promotion and prevention were physical activity (81/200, 40.5%), nutrition (45/200, 22.5%), and sexual health (34/200, 17%). Most of the interventions combined several health promotion or prevention methods, including environmental change; providing information, social support, training, or incentives; and monitoring. Finally, we found that the articles mostly reported on behavioral rather than structural health promotion and prevention.

CONCLUSIONS

The research field of digital health promotion and prevention in settings is heterogeneous. At the same time, we identified research gaps regarding the absence of valid definitions of relevant terms (eg, digital settings) and the lack of literature on structural health promotion and prevention in settings. Therefore, it remains unclear how digital technologies can contribute to structural (or organizational) changes in settings. More research is needed to successfully implement digital technologies to achieve health promotion and prevention in settings.

Joint Longitudinal Models for Dealing With Missing at Random Data in Trial-Based Economic Evaluations

OBJECTIVES

In trial-based economic evaluation, some individuals are typically associated with missing data at some time point, so that their corresponding aggregated outcomes (eg, quality-adjusted life-years) cannot be evaluated. Restricting the analysis to the complete cases is inefficient and can result in biased estimates, while imputation methods are often implemented under a missing at random (MAR) assumption. We propose the use of joint longitudinal models to extend standard approaches by taking into account the longitudinal structure to improve the estimation of the targeted quantities under MAR.

METHODS

We compare the results from methods that handle missingness at an aggregated (case deletion, baseline imputation, and joint aggregated models) and disaggregated (joint longitudinal models) level under MAR. The methods are compared using a simulation study and applied to data from 2 real case studies.

RESULTS

Simulations show that, according to which data affect the missingness process, aggregated methods may lead to biased results, while joint longitudinal models lead to valid inferences under MAR. The analysis of the 2 case studies support these results as both parameter estimates and cost-effectiveness results vary based on the amount of data incorporated into the model.

CONCLUSIONS

Our analyses suggest that methods implemented at the aggregated level are potentially biased under MAR as they ignore the information from the partially observed follow-up data. This limitation can be overcome by extending the analysis to a longitudinal framework using joint models, which can incorporate all the available evidence.

Participant views and experiences of sexual health research: The Contraception Choices online trial

BACKGROUND

Online sexual health research can be convenient, efficient and low cost, but there are debates about the adequacy of online informed consent, privacy, and the acceptability of different methods of follow-up.

OBJECTIVES

To explore women's views and experiences of the Contraception Choices feasibility trial procedures and the place of digital interventions for contraception decision making.

METHODS

We analysed data from two sources: (1) Qualitative interviews. Eighteen interviews were conducted with women who had taken part in the Contraception Choices pre-trial feasibility study, to evaluate recruitment and online trial procedures. (2) Free-text comments. Women in the main Contraception Choices randomised controlled trial were followed up at 3 and 6 months, and asked 'Please tell us what you liked or disliked about the website' and 'Has being in the study had any good or bad effects on your life?' A total of 387 and 414 comments were made at 3 and 6 months respectively. Data were analysed thematically.

RESULTS

Participants liked being involved in a study about contraception, although recruitment from an abortion clinic was less acceptable than in other sexual health settings. Women found the trial procedures straightforward, and expressed no major concerns about online self-registration, informed consent or online data collection. Online survey questions about contraception and fertility were acceptable, and participants liked the convenience of being followed up by email or text.

CONCLUSIONS

Participants appreciated the advantages of the online research design and did not express concerns about consent or privacy. Women would welcome digital interventions for contraception in a variety of settings.

Behavioral Counseling Interventions to Prevent Sexually Transmitted Infections: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Increasing rates of preventable sexually transmitted infections (STIs) in the US pose substantial burdens to health and well-being.

OBJECTIVE

To update evidence for the US Preventive Services Task Force (USPSTF) on effectiveness of behavioral counseling interventions for preventing STIs.

DATA SOURCES

Studies from the previous USPSTF review (2014); literature published January 2013 through May 31, 2019, in MEDLINE, PubMed (for publisher-supplied records only), PsycINFO, and Cochrane Central Register of Controlled Trials. Ongoing surveillance through May 22, 2020.

STUDY SELECTION

Good- and fair-quality randomized and nonrandomized controlled intervention studies of behavioral counseling interventions for adolescents and adults conducted in primary care settings were included. Studies with active comparators only or limited to individuals requiring specialist care for STI risk-related comorbidities were excluded.

DATA EXTRACTION AND SYNTHESIS

Dual risk of bias assessment, with inconsistent ratings adjudicated by a third team member. Study data were abstracted into prespecified forms. Pooled odds ratios (ORs) were estimated using the DerSimonian and Laird method or the restricted maximum likelihood method with Knapp-Hartung adjustment.

MAIN OUTCOMES AND MEASURES

Differences in STI diagnoses, self-reported condom use, and self-reported unprotected sex at 3 months or more after baseline.

RESULTS

The review included 37 randomized trials and 2 nonrandomized controlled intervention studies (N = 65 888; 13 good-quality, 26 fair-quality) recruited from primary care settings in the US. Study populations were composed predominantly of heterosexual adolescents and young adults (12 to 25 years), females, and racial and ethnic minorities at increased risk for STIs. Nineteen trials (n = 52 072) reported STI diagnoses as outcomes (3 to 17 months' follow-up); intervention was associated with reduced STI incidence (OR, 0.66 [95% CI, 0.54-0.81; I2 = 74%]). Absolute differences in STI acquisition between groups varied widely depending on baseline population STI risk and intervention effectiveness, ranging from 19% fewer to 4% more people acquiring STI. Thirty-four trials (n = 21 417) reported behavioral change outcomes. Interventions were associated with self-reported behavioral change (eg, increased condom use) that reduce STI risk (OR, 1.31 [95% CI, 1.10-1.56; I2 = 40%, n = 5253). There was limited evidence on persistence of intervention effects beyond 1 year. No harms were identified in 7 studies (n = 3458) reporting adverse outcomes.

CONCLUSIONS AND RELEVANCE

Behavioral counseling interventions for individuals seeking primary health care were associated with reduced incidence of STIs. Group or individual counseling sessions lasting more than 2 hours were associated with larger reductions in STI incidence, and interventions of shorter duration also were associated with STI prevention, although evidence was limited on whether the STI reductions associated with these interventions persisted beyond 1 year.

Behavioral Counseling Interventions to Prevent Sexually Transmitted Infections: US Preventive Services Task Force Recommendation Statement

IMPORTANCE

Approximately 20 million new cases of bacterial or viral sexually transmitted infections (STIs) occur each year in the US, and about one-half of these cases occur in persons aged 15 to 24 years. Rates of chlamydial, gonococcal, and syphilis infection continue to increase in all regions. Sexually transmitted infections are frequently asymptomatic, which may delay diagnosis and treatment and lead persons to unknowingly transmit STIs to others. Serious consequences of STIs include pelvic inflammatory disease, infertility, cancer, and AIDS.

OBJECTIVE

To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a review of the evidence on the benefits and harms of behavioral counseling interventions for preventing STI acquisition.

POPULATION

This recommendation statement applies to all sexually active adolescents and to adults at increased risk for STIs.

EVIDENCE ASSESSMENT

The USPSTF concludes with moderate certainty that behavioral counseling interventions reduce the likelihood of acquiring STIs in sexually active adolescents and in adults at increased risk, including for example, those who have a current STI, do not use condoms, or have multiple partners, resulting in a moderate net benefit.

RECOMMENDATION

The USPSTF recommends behavioral counseling for all sexually active adolescents and for adults at increased risk for STIs. (B recommendation).

Evidence for behavioural interventions addressing condom use fit and feel issues to improve condom use: a systematic review

Continuing high rates of sexually transmissible infections (STIs) in many countries highlight the need to identify effective behavioural interventions. Consistent and correct use of male condoms is a key strategy for the prevention of STIs. However, some men report problems with condom fit (e.g. the size and shape of the condom) and feel (e.g. tightness, irritation, sensitivity), which inhibits their use. We conducted a systematic review to identify existing interventions addressing condom use fit and feel problems. We searched electronic databases for peer-reviewed articles and searched reference lists of retrieved studies. Five studies met the inclusion criteria. These were generally small-scale pilot studies evaluating behavioural interventions to promote safer sex with men aged under 30 years, addressing, among other things, barriers to condom use relating to fit and feel. There were significant increases in the reported use of condoms, including condom use with no errors and problems. Improvements in some condom use mediators were reported, such as condom use self-efficacy, knowledge, intentions and condom use experience. There were mixed findings in terms of the ability of interventions to reduce STI acquisition. Behavioural interventions addressing condom fit and feel are promising in terms of effectiveness but require further evaluation.

A full Bayesian model to handle structural ones and missingness in economic evaluations from individual-level data

Economic evaluations from individual-level data are an important component of the process of technology appraisal, with a view to informing resource allocation decisions. A critical problem in these analyses is that both effectiveness and cost data typically present some complexity (eg, nonnormality, spikes, and missingness) that should be addressed using appropriate methods. However, in routine analyses, standardised approaches are typically used, possibly leading to biassed inferences. We present a general Bayesian framework that can handle the complexity. We show the benefits of using our approach with a motivating example, the MenSS trial, for which there are spikes at one in the effectiveness and missingness in both outcomes. We contrast a set of increasingly complex models and perform sensitivity analysis to assess the robustness of the conclusions to a range of plausible missingness assumptions. We demonstrate the flexibility of our approach with a second example, the PBS trial, and extend the framework to accommodate the characteristics of the data in this study. This paper highlights the importance of adopting a comprehensive modelling approach to economic evaluations and the strategic advantages of building these complex models within a Bayesian framework.

Improving medication adherence in stroke survivors: the intervention development process

Background

Medications targeting stroke risk factors have shown good efficacy, yet adherence is suboptimal. A lack of underlying theory may contribute to the ineffectiveness of eliciting or sustaining behaviour change in many existing interventions targeting medication adherence in stroke. Intervention effectiveness and implementation could be enhanced by consideration of evidence base and theory to drive development. The purpose of this study is to identify appropriate components for a theory-driven and evidence-based medication adherence intervention for stroke survivors.

Methods

The Behaviour Change Wheel (BCW), a guide to intervention development, informed our systematic process of intervention development. Our earlier systematic review had identified important determinants of medication adherence that were mapped into the Theoretical Domains Framework (TDF), with Knowledge, Beliefs about consequences and Emotions found to be more influential. Utilising the BCW facilitated selection of intervention options and behaviour change techniques (BCTs); the active ingredients within an intervention. To further refine BCT selection, APEASE criteria were employed, allowing evaluation of potential BCTs within context: The National Health Service (NHS), United Kingdom (UK).

Results

Five intervention functions (Education, Persuasion, Training, Environmental Restructuring and Enablement) and five policy categories (Communication/marketing, Guidelines, Regulation, Environmental/social planning and Service provision) were identified as potential intervention options, underpinned by our systematic review findings. Application of APEASE criteria led to an initial pool of 21 BCTs being reduced to 11 (e.g. Habit Formation, Information about Health Consequences and Action Planning) identified as potential intervention components that would both be feasible and directly target the underlying determinants of stroke survivors’ medication adherence.

Conclusions

Careful consideration of underlying evidence and theory to drive intervention design, facilitated by the BCW, enabled identification of appropriate intervention components. BCTs including Habit Formation, Information about Health Consequences and Self-monitoring of Behaviour were considered potentially effective and appropriate to deliver within the NHS. Having reduced the pool of potential intervention components to a manageable number, it will now be possible to explore the perceived acceptability of selected BCTs in interviews with stroke survivors and healthcare professionals. This approach to intervention development should be generalisable to other chronic conditions and areas of behaviour change (e.g. exercise adherence).

Enhancing condom use experiences among young men to improve correct and consistent condom use: feasibility of a home-based intervention strategy (HIS-UK)

BACKGROUND

Condoms remain the main protection against sexually transmitted infections (STIs) when used correctly and consistently. Yet, there are many reported barriers to their use such as negative attitudes, reduced sexual pleasure, fit-and-feel problems and erection difficulties. The UK home-based intervention strategy (HIS-UK) is a behaviour change condom promotion intervention for use among young men (aged 16-25 years) designed to increase condom use by enhancing enjoyment of condom-protected intercourse. The objective of this feasibility study was to test HIS-UK for viability, operability and acceptability. Along with an assessment of the recruitment strategy and adherence to the intervention protocol, the study tested the reliability and suitability of a series of behavioural and condom use outcome measures to assess condom use attitudes, motivations, self-efficacy, use experience, errors and problems and fit and feel.

METHODS

The HIS-UK intervention and associated assessment instruments were tested for feasibility using a single-arm, repeated measures design with baseline measurement and two follow-up measurements over 3 months. A 3-month target of 50 young men completing the baseline questionnaire was set. Twenty process and acceptability evaluation interviews with participants and health promotion professionals were conducted post trial.

RESULTS

Of the 61 young men who registered for the study, 57 completed the baseline questionnaire and 33 met with the study researcher to receive the HIS-UK condom kit. Twenty-one young men remained for the duration of the study (64% retention). The Cronbach's alpha scores for the condom use outcome measures were 0.84 attitudes, 0.78 self-efficacy, 0.83 use experience, 0.69 errors and problems and 0.75 fit and feel. Participant and health professional feedback indicated strong acceptability of the intervention.

CONCLUSIONS

The feasibility study demonstrated that our recruitment strategy was appropriate and the target sample size was achieved. Adherence was favourable when compared to other similar studies. The condom use measures tested proved to be fit-for-purpose with good internal consistency. Some further development and subsequent piloting of HIS-UK is required prior to a full randomised controlled trial, including the feasibility of collecting STI biomarkers, and assessment of participant acceptance of randomisation.

The Use of Intervention Mapping to Develop a Tailored Web-Based Intervention, Condom-HIM

Background

Many HIV (human immunodeficiency virus) prevention interventions are currently being implemented and evaluated, with little information published on their development. A framework highlighting the method of development of an intervention can be used by others wanting to replicate interventions or develop similar interventions to suit other contexts and settings. It provides researchers with a comprehensive development process of the intervention.

Objective

The objective of this paper was to describe how a systematic approach, intervention mapping, was used to develop a tailored Web-based intervention to increase condom use among HIV-positive men who have sex with men.

Methods

The intervention was developed in consultation with a multidisciplinary team composed of academic researchers, community members, Web designers, and the target population. Intervention mapping involved a systematic process of 6 steps: (1) needs assessment; (2) identification of proximal intervention objectives; (3) selection of theory-based intervention methods and practical strategies; (4) development of intervention components and materials; (5) adoption, implementation, and maintenance; and (6) evaluation planning.

Results

The application of intervention mapping resulted in the development of a tailored Web-based intervention for HIV-positive men who have sex with men, called Condom-HIM.

Conclusions

Using intervention mapping as a systematic process to develop interventions is a feasible approach that specifically integrates the use of theory and empirical findings. Outlining the process used to develop a particular intervention provides clarification on the conceptual use of experimental interventions in addition to potentially identifying reasons for intervention failures.
