Filter by:The goal of this clinical trial is to deliver a computer-based working memory training program to improve delay discounting (DD) and prevent substance misuse among at-risk adolescents in a traditionally underserved area. Results from the study will inform future substance use prevention efforts targeted at youth exposed to adverse childhood experiences. Findings will also refine future models of intervention delivery in traditionally underserved communities. The main aims of the project are are: 1) To examine to examine changes in hypothesized mechanisms of substance use initiation and escalation, and 2) to assess whether changes in DD are a mechanism for reducing substance misuse during early adolescence. The investigators will evaluate whether changes in DD following active treatment predict substance use outcomes over the three-month follow-up period.
The purpose of this 32 week study is to use an innovative experimental design known as SMART (Sequential Multiple Assignment Randomized Trial), which will allow us to determine the best way to sequence the delivery of teleexercise (referred to as an adaptive intervention), combined with predictive analytics on participant adherence in a stepped program of physical activity interventions. All 257 participants will have access to a library of recorded video exercise content, and a weekly wellness article. Some participants will receive health coaching calls (1st randomization). Analytic data will be used to determine which participants are responding or not responding to the intervention. Participants not responding after 4 weeks will receive either live one on one or group exercise training (2nd randomization). After 8 weeks, the participant will receive only pre recorded exercise content and articles for another 8 weeks. After final surveys, participants will have open access to the website for another 16 weeks where we will passively observe their fitbit and website data. The study outcomes are: The effectiveness of the adaptive interventions Exploring mediating and moderating variables Sensitivity analysis of the predictive analytics
This is a field trial with a randomized pre-test post-test control group design. This trial is the second phase of an exploratory mixed methods research. Prior to this trial, a qualitative study through in-depth interviews to tour guides from 11 language divisions and also policy makers of Indonesian Tour Guide Association Bali branch (HPI Bali). The education model for tour guides were developed based on the integration of theory of planned behavior (TPB) and identity theory. This educational model is expected to improve the behavior of tour guides in providing travel health information to tourists they serve, which is currently still lacking. However, due to the COVID-19 pandemic, the measurement of behavior can not be conducted. Therefore, this trial aims to test the efficacy of the comprehensive education model to improve the indirect and direct determinants of the behavior namely attitude, subjective norms, perceived behavioral control, role identity, actual behavioral control and behavioral intention. The research hypothesis are: 1. The comprehensive travel health education model improves the attitude of tour guides towards providing travel health information to tourists? 2. The comprehensive travel health education model improves the subjective norms of tour guides towards providing travel health information to tourists? 3. The comprehensive travel health education model improves the perceived behavioral control of tour guides in providing travel health information to tourists? 4. The comprehensive travel health education model improves the role identity of tour guides as a travel health promoter for tourists? 5. The comprehensive travel health education model improves the actual behavioral control of tour guides in providing travel health information to tourists? 6. The comprehensive travel health education model improves the intention of tour guides to provide travel health information to tourists?
