A healthy lifestyle text message intervention for adolescents: protocol for the Health4Me randomized controlled trial

Development and Initial Evaluation of a Digital Phenotype Collection System for Adolescents: Proof-of-Concept Study

BACKGROUND

The growing concern on adolescent mental health calls for proactive early detection and intervention strategies. There is a recognition of the link between digital phenotypes and mental health, drawing attention to their potential use. However, the process of collecting digital phenotype data presents challenges despite its promising prospects.

OBJECTIVE

This study aims to develop and validate system concepts for collecting adolescent digital phenotypes that effectively manage inherent challenges in the process.

METHODS

In a formative investigation (N=34), we observed adolescent self-recording behaviors and conducted interviews to develop design goals. These goals were then translated into system concepts, which included planners resembling interfaces, simplified data input with tags, visual reports on behaviors and moods, and supportive ecological momentary assessment (EMA) prompts. A proof-of-concept study was conducted over 2 weeks (n=16), using tools that simulated the concepts to record daily activities and complete EMA surveys. The effectiveness of the system was evaluated through semistructured interviews, supplemented by an analysis of the frequency of records and responses.

RESULTS

The interview findings revealed overall satisfaction with the system concepts, emphasizing strong support for self-recording. Participants consistently maintained daily records throughout the study period, with no missing data. They particularly valued the recording procedures that aligned well with their self-recording goal of time management, facilitated by the interface design and simplified recording procedures. Visualizations during recording and subsequent report viewing further enhanced engagement by identifying missing data and encouraging deeper self-reflection. The average EMA compliance reached 72%, attributed to a design that faithfully reflected adolescents' lives, with surveys scheduled at convenient times and supportive messages tailored to their daily routines. The high compliance rates observed and positive feedback from participants underscore the potential of our approach in addressing the challenges of collecting digital phenotypes among adolescents.

CONCLUSIONS

Integrating observations of adolescents' recording behavior into the design process proved to be beneficial for developing an effective and highly compliant digital phenotype collection system.

SmilesUp text message intervention for early childhood dental caries prevention: A protocol for a randomised controlled trial

INTRODUCTION

Despite improvements in health outcomes for children, early childhood dental caries (ECC) remains a chronic lifestyle-mediated disease that affects an estimated 600 million children worldwide. Parental influence on oral health-promoting behaviours is pivotal in preventing ECC. The latest WHO publications Ending Early Childhood Dental Caries and Mobile Technologies for Oral Health highlights the opportunity for mobile Health programs (including text message programs) to improve oral health behaviours and oral health self-efficacy. In response, our team of parents, oral health professionals (academics and health promotion experts), and IT specialists co-designed a 12-week, behavioural theory-informed text message program (called SmilesUp) to address behavioural risk factors specific to ECC. This randomised trial aims to assess whether the SmilesUp program improves parents' oral health promoting behaviours (like tooth brushing twice a day with toothpaste) and oral health self-efficacy for their children compared to usual care.

METHODS AND ANALYSIS

A randomised controlled trial with a 1:1 parallel design will be conducted among 150 parents with children diagnosed with ECC and accessing public dental care in NSW, Australia. Patients will be stratified by hospital site, and modality of care (Dental General Anaesthetic (DGA) or not) and then randomly assigned to either immediately receive the SMILESup text messaging intervention or receive the program at the end of the study period. The primary outcome at 12 weeks is twice daily brushing with fluoride toothpaste. Secondary outcomes include changes in the intake frequency of sugared drinks and foods, oral health promoting bedtime routines and oral health self-efficacy. The primary analysis will follow an intention-to-treat principle. In addition, a process evaluation will examine barriers, enablers, and opportunities to scale the program.

ETHICS AND DISSEMINATION

Ethics approval has been obtained from the Western Sydney Local Health District Human Research Ethics Committee 2022/ETH01920. Study results will be disseminated via peer-reviewed publications and presentations at conferences.

TRIAL REGISTRATION

Trial registration number: This clinical trial has been prospectively registered on the ANZCTR from the 27th of March 2023. Registration number: ACTRN12623000325606.

Mitigating Psychological Problems Associated with the 2023 Wildfires in Alberta and Nova Scotia: Six-Week Outcomes from the Text4Hope Program

Background: In 2023, wildfires led to widespread destruction of property and displacement of residents in Alberta and Nova Scotia, Canada. Previous research suggests that wildfires increase the psychological burden of impacted communities, necessitating population-level interventions. Cognitive Behavioural Therapy (CBT)-based text message interventions, Text4HopeAB and Text4HopeNS, were launched in Alberta and Nova Scotia, respectively, during the 2023 wildfire season to support the mental health of impacted individuals. Objectives: The study examines the effectiveness of Text4HopeNS and Text4HopeAB in alleviating psychological symptoms and improving wellbeing among subscribers. Methods: The study involved longitudinal and naturalistic controlled trial designs. The longitudinal study comprised subscribers who completed program surveys at baseline and six weeks post-enrolment, while the naturalistic controlled study compared psychological symptoms in subscribers who had received daily supportive text messages for six weeks (intervention group) and new subscribers who had enrolled in the program during the same period but had not yet received any text messages (control group). The severity of low resilience, poor mental wellbeing, likely Major Depressive Disorder (MDD), likely Generalized Anxiety Disorder (GAD), likely Post-Traumatic Stress Disorder (PTSD), and suicidal ideation were measured on the Brief Resilience Scale (BRS), the World Health Organization-5 Wellbeing Index (WHO-5), Patient Health Questionnaire 9 (PHQ-9), Generalized Anxiety Disorder 7 (GAD-7) scale, PTSD Checklist-Civilian Version (PCL-C), and the ninth question on the PHQ-9, respectively. The paired and independent sample t-tests were employed in data analysis. Results: The results from the longitudinal study indicated a significant reduction in the mean scores on the PHQ-9 (-12.3%), GAD-7 (-14.8%), and the PCL-C (-5.8%), and an increase in the mean score on the WHO-5, but not on the BRS, from baseline to six weeks. In the naturalistic controlled study, the intervention group had a significantly lower mean score on the PHQ-9 (-30.1%), GAD-7 (-29.4%), PCL-C (-17.5%), and the ninth question on the PHQ-9 (-60.0%) which measures the intensity of suicidal ideation, and an increase in the mean score on the WHO-5 (+24.7%), but not on the BRS, from baseline to six weeks compared to the control group. Conclusions: The results of this study suggests that the Text4Hope program is an effective intervention for mitigating psychological symptoms in subscribers during wildfires. This CBT-based text messaging program can be adapted to provide effective support for individuals' mental health, especially in the context of traumatic events and adverse experiences such as those induced by climate change. Policymakers and mental health professionals should consider these findings when shaping strategies for future disaster response efforts, emphasizing the value of scalable and culturally sensitive mental health interventions.

Striking the right balance: co-designing the Health4Me healthy lifestyle digital health intervention with adolescents

BACKGROUND

Adolescents are navigating a period of rapid growth and development within an era of digitalization. Mobile phone ownership among adolescents is nearly ubiquitous, and this provides an opportunity to harness text messaging to promote a healthy lifestyle and reduce chronic disease risk factors. Inclusion of adolescents throughout the design process has been recognized as essential for engagement and future implementation of such interventions. This study aimed to co-design a bank of text messages to promote a healthy lifestyle which are useful, acceptable, and engaging for adolescents aged 12-18 years old.

METHODS

Iterative, mixed-methods design with consumer partnership. Co-design occurred over three stages: text message development, text message review and final refinement and testing. The text message development included literature searches and consumer partnership with an established youth advisory group (n = 16). Participants who gave e-consent participated in text message review. Demographic characteristics were collected, and quantitative surveys were distributed to adolescents (n = up to 50) and health professionals (n = up to 30), who rated text message content for understanding, usefulness and appropriateness (total score out of 15). Final refinement was completed by the research team to edit or remove messages which had low scores and to assess readability and interactivity of the text messages.

RESULTS

The Heath Advisory Panel for Youth at the University of Sydney (HAPYUS) identified the top six lifestyle health issues for young people today in relation to chronic disease prevention, which became the key content areas for the text message bank and drafted new text messages. Following text message development, 218 messages were available for review. Adolescents (n = 18, mean age 16.3 [SD 1.4]) and healthcare professionals (n = 16) reviewed the text messages. On average, all reviewers found that the text messages were easy to understand (mean = 13.4/15) and useful (mean = 12.7/15). Based on scoring and open ended-feedback, 91 text messages were edited and 42 deleted. The final text message bank included 131 text messages. The overall program is suitable for a seventh-grade reading level, and interactive.

CONCLUSIONS

This study describes the process of effectively engaging adolescents to co-design a text message bank intervention, which are useful, acceptable and engaging for an adolescent audience. The effectiveness of the co-designed text message bank is currently being tested in the Health4Me RCT.

Evaluating the effect of a 12-month youth advisory group on adolescent's leadership skills and perceptions related to chronic disease prevention research: a mixed-methods study

BACKGROUND

Youth Advisory Groups (YAGs) represent a promising method to engage adolescents in research of relevance to them and their peers. However, YAGs are rarely implemented or evaluated in chronic disease prevention research. The aims of this study were firstly, to evaluate the effect of participation in a 12-month YAG on adolescents' leadership skills and perceptions related to chronic disease prevention research and secondly, to evaluate the process of establishing and facilitating a 12-month YAG and identify barriers and enablers to establishment and facilitation.

METHODS

This study was a 12-month pre-post study. Eligible participants were adolescents (13-18-years) and current members of an established YAG. Data collection involved online surveys and semi-structured interviews at baseline, six-months and 12-months follow-up. Participatory outcomes such as self-efficacy, leadership skills, and collective participation were derived from Youth Participatory Action Research Principles (YPAR), and the Lansdown-UNICEF conceptual framework for measuring outcomes of adolescent participation. Process evaluation data were captured via meeting minutes, Slack metrics and researcher logs. Quantitative data was analysed using descriptive statistics and qualitative data was thematically analysed using a reflexive thematic analysis approach.

RESULTS

Thirteen (13/16) YAG youth advisors consented to participate in the evaluation study (mean age 16.0 years, SD 1.3; 62% (8/13) identified as female). Survey data assessing participatory outcomes found an increase in leadership and life skills scores over 12-months (+ 8.90 points). Semi-structured interview data collected over the 12-month term revealed three key themes namely: influence, empowerment, and contribution. Comparison of pre-post themes determined a positive trend at follow-ups, demonstrating improved participatory outcomes. Process indicators revealed that at 12-month follow-up the YAG was implemented as planned. Semi-structured interview data determined barriers to YAG facilitation included time and limited face-to-face components, while enablers to YAG facilitation included flexibility, accessible delivery methods, and a supportive adult facilitator.

CONCLUSION

This study found that a YAG fostered positive participatory outcomes and unique opportunities for youth participants. A successful YAG based on YPAR principles requires researchers to ensure YAG establishment and facilitation is an iterative process. Taking into consideration important barriers and enablers to YAG facilitation ensures adolescent engagement in a YAG is both meaningful and impactful.

A National Health and Wellness SMS Text Message Program for Breast Cancer Survivors During COVID-19 (EMPOWER-SMS COVID-19): Mixed Methods Evaluation Using the RE-AIM Framework

BACKGROUND

COVID-19 lockdowns caused widespread closures of supportive care services for breast cancer survivors in Australia. In a randomized controlled trial, our team's lifestyle-focused, evidence-based SMS text message support program (EMPOWER-SMS COVID-19) was found to be acceptable and useful for breast cancer survivors, and it was ready for rapid widespread delivery.

OBJECTIVE

This study aims to evaluate the reach (uptake) of an adapted 3-month lifestyle-focused SMS text message program (EMPOWER-SMS COVID-19) and barriers and enablers to implementation using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.

METHODS

A mixed methods pre-post study was conducted to evaluate the EMPOWER-SMS COVID-19 program. The study evaluated the following aspects: (1) reach/representativeness, which refers to the proportion of participant enrollment (ie, number enrolled/number that visited the study website) and demographics (eg, age, sex, ethnicity, time since completing treatment, Index of Relative Socio-economic Advantage and Disadvantage [IRSAD; quintile 1, which refers to most disadvantaged areas, to quintile 5, which refers to least disadvantaged areas, and remoteness); (2) effectiveness, in which participant engagement and acceptability were evaluated using SMS text message reply data and a feedback survey (5-point Likert scale and free-text responses); (3) adoption, which corresponds to the proportion of organizations or health professionals who agreed to promote the program; (4) implementation fidelity and maintenance, which evaluated SMS text message delivery data, opt-outs, costs, and adaptations. Quantitative data were summarized using means and SDs or frequencies and percentages, while qualitative data were analyzed thematically.

RESULTS

With regard to the reach/representativeness of the program, 841/1340 (62.8%) participants enrolled and provided electronic consent. Participants had a mean age of 58.8 (SD 9.8; range 30-87) years. According to the data collected, most participants identified as female (837/840, 99.6%) and White (736/840, 87.6%) and nearly half (418/841, 49.7%) finished treatment ≤18 months ago. Most resided in major cities (574/838, 68.5%) and 30% (251/838) in IRSAD quintile 1 or 2. In terms of effectiveness, 852 replies were received from 511 unique participants (median 1; range 1-26). The most common replies were participants stating how they heard about the program (467/852, 54.8%) or "thank you" (131/852, 15.4%). None of the replies contained urgent safety concerns. Among participants who provided feedback (449/841, 53.4%), most "(strongly) agreed" the SMS text messages were easy to understand (445/448, 99.3%), useful (373/440, 84.8%), helped participants feel supported (388/448, 86.6%), and motivated participants to be physically active (312/445, 70.1%) and eat healthier (313/457, 68.5%). Free-text responses revealed 5 factors influencing engagement: (1) feeling supported and less alone, (2) motivation and reassurance for health self-management, (3) the variety of information, (4) weblinks to information and resources, and (5) the option to save the SMS text messages. Concerning adoption, 50% (18/36) of organizations/health professionals agreed to promote the program. With regard to implementation/maintenance, SMS text messages were delivered as planned (97.43% [41,257/42,344] of SMS text messages were successfully delivered) with minimal opt-outs (62/838, 7.4%) and low cost (Aus $15.40/participant; Aus $1=US $0.67). No adaptations were made during the intervention period. Postintervention adaptations included adding weblinks and participant-selected customizations.

CONCLUSIONS

EMPOWER-SMS COVID-19 was implemented quickly, had a broad reach, and had high engagement and acceptability among socioeconomically diverse participants. The program had high fidelity, low cost, and required minimal staff oversight, which may facilitate future implementation. However, further research is needed to evaluate barriers and enablers to adoption and implementation for health professionals and strategies for long-term maintenance.

Feasibility and Acceptability of Chatbots for Nutrition and Physical Activity Health Promotion Among Adolescents: Systematic Scoping Review With Adolescent Consultation

BACKGROUND

Reducing lifestyle risk behaviors among adolescents depends on access to age-appropriate health promotion information. Chatbots-computer programs designed to simulate conversations with human users-have the potential to deliver health information to adolescents to improve their lifestyle behaviors and support behavior change, but research on the feasibility and acceptability of chatbots in the adolescent population is unknown.

OBJECTIVE

This systematic scoping review aims to evaluate the feasibility and acceptability of chatbots in nutrition and physical activity interventions among adolescents. A secondary aim is to consult adolescents to identify features of chatbots that are acceptable and feasible.

METHODS

We searched 6 electronic databases from March to April 2022 (MEDLINE, Embase, Joanna Briggs Institute, the Cumulative Index to Nursing and Allied Health, the Association for Computing Machinery library, and the IT database Institute of Electrical and Electronics Engineers). Peer-reviewed studies were included that were conducted in the adolescent population (10-19 years old) without any chronic disease, except obesity or type 2 diabetes, and assessed chatbots used nutrition or physical activity interventions or both that encouraged individuals to meet dietary or physical activity guidelines and support positive behavior change. Studies were screened by 2 independent reviewers, with any queries resolved by a third reviewer. Data were extracted into tables and collated in a narrative summary. Gray literature searches were also undertaken. Results of the scoping review were presented to a diverse youth advisory group (N=16, 13-18 years old) to gain insights into this topic beyond what is published in the literature.

RESULTS

The search identified 5558 papers, with 5 (0.1%) studies describing 5 chatbots meeting the inclusion criteria. The 5 chatbots were supported by mobile apps using a combination of the following features: personalized feedback, conversational agents, gamification, and monitoring of behavior change. Of the 5 studies, 2 (40.0%) studies focused on nutrition, 2 (40.0%) studies focused on physical activity, and 1 (20.0%) focused on both nutrition and physical activity. Feasibility and acceptability varied across the 5 studies, with usage rates above 50% in 3 (60.0%) studies. In addition, 3 (60.0%) studies reported health-related outcomes, with only 1 (20.0%) study showing promising effects of the intervention. Adolescents presented novel concerns around the use of chatbots in nutrition and physical activity interventions, including ethical concerns and the use of false or misleading information.

CONCLUSIONS

Limited research is available on chatbots in adolescent nutrition and physical activity interventions, finding insufficient evidence on the acceptability and feasibility of chatbots in the adolescent population. Similarly, adolescent consultation identified issues in the design features that have not been mentioned in the published literature. Therefore, chatbot codesign with adolescents may help ensure that such technology is feasible and acceptable to an adolescent population.
