RESUMEN
BACKGROUND: The high prevalence of cannabis use among young adults poses substantial global health concerns due to the associated acute and long-term health and psychosocial risks. Digital modalities, including websites, digital platforms, and mobile apps, have emerged as promising tools to enhance the accessibility and availability of evidence-based interventions for young adults for cannabis use. However, existing reviews do not consider young adults specifically, combine cannabis-related outcomes with those of many other substances in their meta-analytical results, and do not solely target interventions for cannabis use. OBJECTIVE: We aimed to evaluate the effectiveness and active ingredients of digital interventions designed specifically for cannabis use among young adults living in the community. METHODS: We conducted a systematic search of 7 databases for empirical studies published between database inception and February 13, 2023, assessing the following outcomes: cannabis use (frequency, quantity, or both) and cannabis-related negative consequences. The reference lists of included studies were consulted, and forward citation searching was also conducted. We included randomized studies assessing web- or mobile-based interventions that included a comparator or control group. Studies were excluded if they targeted other substance use (eg, alcohol), did not report cannabis use separately as an outcome, did not include young adults (aged 16-35 y), had unpublished data, were delivered via teleconference through mobile phones and computers or in a hospital-based setting, or involved people with mental health disorders or substance use disorders or dependence. Data were independently extracted by 2 reviewers using a pilot-tested extraction form. Authors were contacted to clarify study details and obtain additional data. The characteristics of the included studies, study participants, digital interventions, and their comparators were summarized. Meta-analysis results were combined using a random-effects model and pooled as standardized mean differences. RESULTS: Of 6606 unique records, 19 (0.29%) were included (n=6710 participants). Half (9/19, 47%) of these articles reported an intervention effect on cannabis use frequency. The digital interventions included in the review were mostly web-based. A total of 184 behavior change techniques were identified across the interventions (range 5-19), and feedback on behavior was the most frequently used (17/19, 89%). Digital interventions for young adults reduced cannabis use frequency at the 3-month follow-up compared to control conditions (including passive and active controls) by -6.79 days of use in the previous month (95% CI -9.59 to -4.00; P<.001). CONCLUSIONS: Our results indicate the potential of digital interventions to reduce cannabis use in young adults but raise important questions about what optimal exposure dose could be more effective, both in terms of intervention duration and frequency. Further high-quality research is still needed to investigate the effects of digital interventions on cannabis use among young adults.

OBJECTIVE: Young adults (18- to 24-year-olds) constitute the age group with the highest proportion of cannabis users. In the context of legalization, it is important to promote lower-risk cannabis use. The Protective Behavioral Strategies for Marijuana Scale (PBSM-17) identifies strategies used by consumers. However, this scale is not available in French and is not adapted to the Canadian context. This article presents the process that led to the translation, cultural adaptation and evaluation of the preliminary psychometric properties of PBSM-17. METHOD: The methodological study was carried out in six steps. The first four steps led to the translation towards French and adaptation of the scale. A validation among 12 young people contributed to establish the criterion equivalency (step 5). The evaluation of psychometric properties (step 6) was carried out among 211 bilingual university students (61 % women; mean age 22 years old). RESULTS: The French version presents satisfactory preliminary psychometric properties: internal consistency is acceptable (α = 0.88); criterion equivalency was established between the French and the original English version (t (210) = 1.04, p = 0.30; 95% CI [-0.20, 0.63]). The scores obtained on both versions by the same participant were found to be strongly correlated (r = 0.95, p <0.001). CONCLUSION: The results support the use of the French version of PBSM-17. The proposed protective strategies can be used as a measurement tool and represent behaviors that can be targeted in a lower-risk cannabis use context.
OBJECTIF: Les jeunes de 18 à 24 ans constituent la plus grande proportion de consommateurs de cannabis. Dans un contexte de légalisation de cette substance, il importe de promouvoir une consommation à moindre risque. L'échelle Protective Behavioral Strategies for Marijuana Scale (PBSM-17) permet d'identifier les stratégies de protection comportementale utilisées chez les consommateurs. Toutefois, cette échelle n'est pas disponible en français et n'est pas adaptée au contexte canadien. Cet article présente la démarche ayant mené à la traduction, l'adaptation culturelle et l'évaluation des propriétés psychométriques préliminaires du PBSM-17. MÉTHODE: L'étude méthodologique s'est déroulée en six étapes. Les quatre premières étapes ont mené à la traduction et l'adaptation de l'échelle. La validation auprès de 12 jeunes a permis d'établir l'équivalence conceptuelle. L'évaluation des propriétés psychométriques a été réalisée auprès de 211 étudiants universitaires bilingues (61 % femme; âge moyen 22 ans). RÉSULTATS: La version traduite et adaptée présente des propriétés psychométriques préliminaires satisfaisantes : la cohérence interne est acceptable (α = 0,88); l'équivalence de critères (validité de construit) est établie entre la version française et la version anglaise (t (210) = 1,04, p = 0,30 ; IC 95 % [-0,20, 0,63]). Les scores obtenus aux deux versions par le même participant s'avèrent fortement corrélées (r = 0,95, p < 0,001). CONCLUSION: Les résultats soutiennent l'utilisation de la version française du PBSM-17. Les stratégies de protection proposées peuvent être utilisées comme outil de mesure et représentent des comportements à adopter dans un contexte d'usage du cannabis à moindre risque.

OBJECTIVE: A web-based intervention was developed to support epilepsy self-management. A mixed methods study was undertaken to evaluate the intervention's extent of utilization, acceptability and preliminary effects, and to assess user perception of it. METHODS: First, a pilot parallel-group randomized controlled trial was conducted with a convenience sample of 75 adult with epilepsy who had Internet access allocated on a 1:1 ratio into an experimental group that received the intervention (experimental group (EG), nâ¯=â¯37) and a control group invited to consult epilepsy-related websites (control group (CG), nâ¯=â¯38). Self-management, knowledge, and quality of life (QoL) outcomes were measured at baseline and one and three months later. Descriptive statistics of extent of utilization and acceptability were computed. Linear mixed models were conducted to assess change in outcomes over time and between groups. Subsequently, an exploratory qualitative study was carried out with 15 EG participants. Qualitative data were subjected to thematic analysis. RESULTS: Participants had a mean age of 40â¯years (range: 18-73), 45% were female, and mean time since diagnosis was 18â¯years (range: less than a year to 60â¯years). In the EG, 70% of the participants completed the intervention. Regarding acceptability, participants (nâ¯=â¯25) were satisfied overall (88%) and found content clear (92%) and the information reliable (100%). EG participants experienced greater improvement in QoL compared with CG participants, least-squares means (95% CI): 0.41 (0.06, 0.76). Three major themes emerged from the interviews (nâ¯=â¯15): intervention provides certain personal benefits; clinical content is of general interest but should be tailored; and intervention should target "new" patients early in the care trajectory. DISCUSSION: The web-based intervention shows promise in terms of usefulness in enhancing QoL, and user experience showed that it is acceptable and helpful. It could constitute a complementary service in support of existing services for people with epilepsy and their families.

BACKGROUND: Optimizing care continuum entry interventions is key to ending the HIV epidemic. Offering HIV screening to key populations in emergency departments (EDs) is a strategy that has been demonstrated to be effective. Analyzing patient and provider perceptions of such screening can help identify implementation facilitators and barriers. OBJECTIVES: The aim of this study was to investigate the acceptability of offering nurse-driven HIV screening to key populations based on data collected from patients, nurses, and other service providers. METHODS: This convergent mixed-methods study was a substudy of a cluster-randomized two-period crossover trial conducted in eight EDs to evaluate the effectiveness of the screening strategy. During the DICI-VIH (Dépistage Infirmier CIblé du VIH) trial, questionnaires were distributed to patients aged 18-64 years. Based on their responses, nurses offered screening to members of key populations.Over 5 days during the intervention period in four EDs, 218 patients were secondarily questioned about the acceptability of screening. Nurses completed 271 questionnaires pre- and posttrial regarding acceptability in all eight EDs. Descriptive analyses were conducted on these quantitative data. Convenience and purposeful sampling was used to recruit 53 providers to be interviewed posttrial. Two coders conducted a directed qualitative content analysis of the interview transcripts independently. RESULTS: The vast majority of patients (95%) were comfortable with questions asked to determine membership in key populations and agreed (89%) that screening should be offered to key populations in EDs. Nurses mostly agreed that offering screening to key populations was well accepted by patients (62.2% pretrial and 71.4% posttrial), was easy to implement, and fell within the nursing sphere of competence. Pretrial, 73% of the nurses felt that such screening could be implemented in EDs. Posttrial, the proportion was 41%. Three themes emerged from the interviews: preference for targeted screening and a written questionnaire to identify key populations, facilitators of long-term implementation, and implementation barriers. Nurses were favorable to such screening provided specific conditions were met regarding training, support, collective involvement, and flexibility of application to overcome organizational and individual barriers. DISCUSSION: Screening for key populations was perceived as acceptable and beneficial by patients and providers. Addressing the identified facilitators and barriers would help increase screening implementation in EDs.

Optimal adherence to immunosuppressive medication is essential to kidney graft success. A Web-based tailored virtual nursing intervention was developed to promote medication adherence and support self-management among kidney transplant recipients. A qualitative study was undertaken in a hospital setting in Montreal (Canada) to document how users experience the intervention and to explore medication intake self-management behaviors. To participate, transplant recipients had to be at least 18 years old and had to have completed at least one computer session of the intervention. Semistructured interviews were conducted with 10 participants (two women, eight men) with a mean age of 47.8 years. They reported receiving their latest renal transplant on average 10.6 years prior. Content analysis of the interview transcripts yielded five major themes: (1) kidney transplant is a gift from life; (2) routinization of medication intake; (3) intervention is a new and positive experience; (4) using the intervention offers many benefits; and (5) individual relevance of the intervention. Patient experience shows the intervention is acceptable and can help better manage medication intake. Results also underscore the importance of offering the intervention early in the care trajectory of transplant recipients. Web-based tailored virtual nursing interventions could constitute an easily available adjunct to existing specialized services.

BACKGROUND: Long-term use of antiretroviral therapy, normal aging, and presence of certain risk factors are associated with metabolic disorders that predispose persons living with HIV to diabetes and cardiovascular diseases. The emergence and progression of these disorders can be prevented by adopting healthy behaviours. Based on the theory of planned behaviour, the Web-based tailored intervention TAVIE en santé was developed. The aim of this study is to evaluate the effectiveness of TAVIE en santé in order to support people living with HIV in the adoption of health promoting behaviours. METHODS/DESIGN: An online randomized controlled trial with parallel-groups will be conducted across Canada. To participate in this study, people living with HIV must be: ≥ 18 years, able to read/understand French or English, have access to the Internet. A convenience sample of 750 participants will be randomly assigned either to an experimental group (TAVIE en santé, n = 375) or to a control group (websites, n = 375) (1:1 allocation ratio). The TAVIE en santé intervention is composed of seven interactive computer sessions, lasting between 5 and 10 min. The sessions, hosted by a virtual nurse, aim to develop and strengthen skills required for behaviour change. The control group will receive a validated list of five predetermined conventional health-related Websites. The adoption of health behaviour (smoking cessation or physical activity or healthy eating) is the principal outcome. Cognitions (intention, attitude, perceived behavioral control) are the secondary outcomes. Health indicators will also be assessed. All outcomes will be measured with a self-administered online questionnaire and collected three times: at baseline, 3 and 6 months after. The principal analyses will focus on differences between the two trial groups using Intention-to-Treat analysis. DISCUSSION: This study will yield new results about the efficacy of Web-based tailored health behaviours change interventions in the context of chronic disease. The TAVIE en santé intervention could constitute an accessible complementary service in support of existing specialized services to support people living with HIV adopt health behaviors.

BACKGROUND: The Protective Behavioural Strategies for Marijuana (PBSM-17) scale serves to identify and measure strategies employed by young adults before, during or after cannabis use. After the adaptation and translation of the PBSM-17 into French, a methodological study was conducted to evaluate the psychometric properties of this French version (FV) and of the original English version (EV) in a sample of bilingual Canadian university students. METHODS: A total of 211 cannabis users (mean age=22.1 years) completed a sociodemographic questionnaire, a question on frequency of cannabis use (four categories: 1-3 times a month, once a week, more than once a week, everyday) and both versions (FV and EV) of the PBSM-17. RESULTS: Both versions had similar internal reliability (α=0.91; α=0.88). The one-factor solution explained 36.46% of the variance for the FV and 42.26% for the EV. As hypothesised, greater use of protective behavioural strategies was related to lower frequency of cannabis use. One-way ANOVA test results revealed a statistically significant difference in use of strategies by frequency of cannabis use for both the FV (F(3, 207)=27.38, p<0.001) and EV (F(3, 207)=29.32, p<0.001). Post hoc comparisons showed that everyday users employed fewer strategies on average than lower-frequency users. CONCLUSION: The FV and EV of the PBSM-17 demonstrated satisfactory psychometric properties. The proposed FV of the PBSM-17 is a reliable instrument that could be used for research and clinical purposes. Protective behavioural strategies can serve as indicator of lower-risk cannabis use and could be targeted in prevention interventions.

BACKGROUND: Taking antiretroviral therapy (ART) is part of the daily life of people living with HIV. Different electronic health (eHealth) initiatives adjunctive to usual care have been proposed to support optimal medication adherence. A web-based intervention called HIV Treatment, Virtual Nursing Assistance, and Education or VIH-TAVIE (from its French version Virus de l'immunodéficience humaine-Traitement assistance virtuelle infirmière et enseignement) was developed to empower people living with HIV to manage their ART and symptoms optimally. OBJECTIVE: We aimed to evaluate the effectiveness of VIH-TAVIE in a web-based randomized controlled trial (RCT). METHODS: This RCT was entirely web-based, including recruitment, consent granting, questionnaire completion, and intervention exposure (consultation with VIH-TAVIE [experimental group] or websites [control group]). To be eligible for the study, people living with HIV had to be 18 years or older, be on ART for at least 6 months, have internet access, and have internet literacy. Participants were randomly assigned to either the experimental group (n=45) or control group (n=43). The primary outcome was ART adherence. The secondary outcomes included self-efficacy regarding medication intake, symptom-related discomfort, skills and strategies, and social support. All outcomes were measured with a self-administered web-based questionnaire at the following three time points: baseline and 3 and 6 months later. A generalized linear mixed model was built to assess the evolution of ART adherence over time in both groups. RESULTS: The sample included 88 participants, and of these, 73 (83%) were men. The median age of the participants was 42 years. Participants had been diagnosed with HIV a median of 7 years earlier (IQR 3-17) and had been on ART for a median of 5 years (IQR 2-12). The proportion of treatment-adherent participants at baseline was high in both groups (34/41, 83% in the experimental group and 30/39, 77% in the control group). Participants also reported high treatment adherence, high self-efficacy, and high skills; perceived good social support; and experienced low discomfort from symptoms. Analyses revealed no intergroup difference regarding ART adherence (OR 1.9, 95% CI 0.6-6.4). CONCLUSIONS: This study highlights the challenges and lessons learned from conducting an entirely web-based RCT among people living with HIV. The challenges were related to the engagement of people living with HIV on the following three levels: starting the web-based study (recruitment), completing the web-based intervention (engagement), and continuing the study (retention). The results contribute to the existing body of knowledge regarding how to conduct web-based evaluation studies of eHealth interventions aimed at developing and strengthening personal skills and abilities.

BACKGROUND: Optimal immunosuppressive medication adherence is essential to graft survival. Transplant-TAVIE is a Web-based tailored intervention developed to promote this adherence. OBJECTIVE: The objective of our study was to evaluate the Transplant-TAVIE intervention's acceptability, feasibility, and preliminary efficacy. METHODS: In a pilot, parallel-group, randomized controlled trial, we randomly assigned a convenience sample of 70 kidney transplant patients on immunosuppressive medication either to an experimental group (Transplant-TAVIE) or to a control group (existing websites). Kidney transplant recipients had to be older than 18 years, be taking immunosuppressant medication, and have access to the internet to participate in this study. Transplant-TAVIE was composed of three interactive Web-based sessions hosted by a virtual nurse. We documented user appreciation of and exposure to the intervention. Furthermore, we assessed medication adherence, medication self-efficacy, intake-related skills, and medication side effects at baseline and 3 and 6 months later. Analyses of variance were used to assess intergroup differences over time. RESULTS: After baseline questionnaire completion, participants were randomly assigned either to Transplant-TAVIE (n=35) or to the websites (n=35) group. All participants had received their kidney graft <1 year to 32 years earlier (mean 6.8 years). Of the experimental group, 54% (19/35) completed the sessions of Transplant-TAVIE. Users found the intervention to be acceptable-33% were extremely satisfied (6/18), 39% were very satisfied (7/18), and 28% were satisfied (5/18). At baseline and over time, both experimental and control groups reported high medication adherence, high medication self-efficacy, and frequent use of skills related to medication intake. No intergroup differences emerged over time. CONCLUSIONS: The results of this study support the feasibility and acceptability of Transplant-TAVIE. It could constitute an accessible adjunct in support of existing specialized services.
RESUMEN
Background. In the domain of health behavior change, the deployment and utilization of information and communications technologies as a way to deliver interventions appear to be promising. This article describes the development of a web-based tailored intervention, TAVIE en santé, to support people living with HIV in the adoption of healthy behaviors. Methods. This intervention was developed through an Intervention Mapping (IM) framework and is based on the theory of planned behavior. Results. Crucial steps of IM are the selection of key determinants of behavior and the selection of useful theory-based intervention methods to change the targeted determinants (active ingredients). The content and the sequence of the intervention are then created based on these parameters. TAVIE en santé is composed of 7 interactive web sessions hosted by a virtual nurse. It aims to develop and strengthen skills required for behavior change. Based on an algorithm using individual cognitive data (attitude, perceived behavioral control, and intention), the number of sessions, theory-based intervention methods, and messages contents are tailored to each user. Conclusion. TAVIE en santé is currently being evaluated. The use of IM allows developing intervention with a systematic approach based on theory, empirical evidence, and clinical and experiential knowledge.

PURPOSE: Antiretroviral therapy medication adherence is a complex phenomenon influenced by multiple factors. This study examines its evolution and predictors among perinatally HIV-infected youths in São Paulo, Brazil. METHODS: During a 1-year longitudinal cohort study, perinatally HIV-infected youths aged 13-21 years taking antiretroviral therapy were recruited in hospitals and HIV/AIDS reference centers. Data were collected at baseline and after 12 months. Variables assessed were adherence, self-efficacy regarding medication intake, social support, stress level, depression, CD4 cell count, viral load, and symptoms. Adherence was defined as taking ≥95% of prescribed HIV medication in the past 7 days. Generalized estimating equation and analysis of variance methods were used. RESULTS: A total of 268 adolescents participated in the study (59% female; mean age of 16 years). At baseline, 63.06% of the sample was adherent to their HIV medication, and 52.99% had an undetectable viral load. All participants, regardless of adherence, reported: low levels of stress and symptoms of depression; high perception of medication self-efficacy and social support; and a mean of 6.8 symptoms related to their HIV medication. Predictors of adherence were: high perception of medication self-efficacy (odds ratio = 2.81; 95% confidence interval: 1.94-4.05) and low number of reported medication side effects (odds ratio = .97; 95% confidence interval: .95-.99]. Between baseline and follow-up, 49.6% remained adherent, 22.3% remained nonadherent, and the adherence level changed over time for 28.2%. CONCLUSIONS: These findings suggest the need to develop interventions to enhance self-efficacy toward medication and to help youth better manage HIV medication symptoms.
