An Intervention to Protect Young Children From Tobacco Smoke Exposure

Phase 3
Conditions
Passive Smoking
Interventions
Behavioral: Behavioral Late
Behavioral: Behavioral Early
Registration Number
NCT02867241
Lead Sponsor
Laura J. Rosen
Brief Summary

The primary goal of this research is to evaluate the effectiveness of an intervention for parents to reduce tobacco smoke exposure of young children

Detailed Description

The primary aim of this intervention is to reduce exposure of children to tobacco smoke, through an intervention program designed to help parents better perceive exposure and its harms, and to provide tools for assisting them in protecting children. Secondary aims are to understand the relationships between parentally-reported and objectively measured child tobacco smoke exposure, to assess the relationship between tobacco smoke exposure and health and health care utilization, and to better understand parental perceptions of tobacco smoke exposure (PPE) and parental perceptions of risk (PPR) from tobacco smoke exposure. The effectiveness of the intervention will be evaluated using a randomized controlled trial.

This RCT is a continuation of previous work. Originally the entire research project, which included a Pilot Study and a Randomized Controlled Trial (RCT) was registered as NCT01335178. Upon completion of the Pilot Study, we closed NCT01335178 and opened a new one for the RCT with the current registration number.

GroupInterventionDescription
Control ExpandedBehavioral LateThis group will get no intervention during the study period. However, participants will fill out a detailed questionnaire on parental perceptions of exposure and risk, as well as questions on social norms, self-efficacy, and knowledge Following the close of the study, participants in this group will receive a shortened version of the intervention (1 motivational interview, with feedback on child hair nicotine levels and feedback on home air quality (PM2.5))
Control RegularBehavioral LateThis group will get no intervention during the study period. Following the close of the study, participants in this group will receive a shortened version of the intervention (1 motivational interview, with feedback on child hair nicotine levels and feedback on home air quality (PM2.5))
InterventionBehavioral Early1. Motivational interviews (3 visits) + supportive phone calls 2. Feedback of child hair nicotine levels 3. Feedback of home air quality (PM2.5) 4. New Media (Website and/or Facebook with information and parental forum)
