Second & Third-Hand Smoke Exposure in Private Homes: Current & Future Clinical Interventions & Ecological ContextsThe Johns Hopkins University3/28/11
The Behavioral Ecological Model • Based on Biology/Ecology • Selection of Species • Selection of Behavior • Principles of Learning Across All Animal Species • Emphasizes Environment Determinants • Based on Principles of Learning • Contingencies of Reinforcement—incentives or rewards • Hierarchical & interacting contingencies • Meta-and Macro-contjngencies • Motivating operations or Moderating Factors
The Problem with Behavior • It is a stream • It’s a stream interacting with the environment • The entire environment is also a stream • Neither will hold still • It’s very hard to measure a stream • It’s almost impossible to measure multiple streams • Measuring Streams is prerequisite to Modifying behavior • Measuring Multiple behaviors from multiple people residing in multiple social networks are the streams to be targeted by behavioral science

BEHAVIORAL COUNSELING PROGRAM • Parents contract to reduce their child’s ETS Exposure • Short-term goals • Self-monitoring • Positive feedback • Problem-solving brainstorming • Recruitment of social contingencies • 4-14 sessions in the home and by phone
~ The Role of Clinicians ~ • Nonsmoker Models • Deliver Tobacco Control Services • Contract with parents and other family members • Address ETS as Lead contamination • Promote Policies for reimbursement of tobacco control services • Promote Laws restricting ETS exposure community-wide • Most providers do few of these
Cross Validity of Measures Contamination: Exposure: Child Urine Cotinine ------.65------- Indoor Air Nicotine | | | | | | __________ | | .63 _________\___ | .62 | / \ | | .71 .41 | | / \ | Reported Indoor ------.78--------- Reported Smoking in Smoking presence of the child
Results: Cotinine (geometric means) • Intervention Phase • Group by time (linear) interaction significant (p<.05) • Follow-up Phase • Group by time interaction nonsignificant

THS Exposure in Homes of Smokers and Nonsmokers No Exposure: Nonsmoking Parents, no known exposure of child Indirect: Smoking parents, no indoor smoking at home Direct: Smoking parents, indoor smoking at home Matt, G.E., et al.

Figure 3 Real Time Telemetry and Feedback: SHS exposure
Legislative and other Policies: Macro-contingencies that may alter clinical metacontingencies
Dose Effect – Tobacco-Use Incidence and Anti-Tobacco Prescriptions * Significant differences between group that received 0-1 prescription.
Proportion of participants who initiated tobacco use stratified by experimental group and “friends who think smoking is cool”
Social Criticism in Public Places Percentage of respondents who considered it VERY LIKELY TO BE CRITICIZED for smoking inside public places
Conclusions: Anti-tobacco cultures are contagious • Differences in social criticism of tobacco varying by proximity, • Differences in Home bans differ by proximity to California • Workplace bans moderate city effects on home bans • Suggests that the exposure to the California anti-tobacco culture is changing the culture of Tijuana.
What do we think? • Counseling can decrease SHSe • Context Enhances or weakens counseling • Measurement reactivity weakens g x t sign • SHSe & THSe requires changes in Social Networks, including Providers • Real time Feedback may enhance SHSe and THSe control • Cascading Contingencies Change Cultures
