Summary
Financial incentive treatments (FITs) adapted for couples where both partners smoke were feasible and well-tolerated. These partner-involved FITs show promise for increasing smoking cessation rates in dual-smoker couples.
Area of Science:
- Behavioral Science
- Public Health
- Addiction Medicine
Background:
- Dual-smoker couples face unique challenges in smoking cessation, with higher relapse rates.
- Traditional cessation methods may be less effective for individuals in smoking partnerships.
Purpose of the Study:
- To assess the feasibility and tolerability of dyadic adaptations of financial incentive treatments (FITs) for dual-smoker couples.
- To explore preliminary efficacy of partner-involved FITs in promoting smoking cessation.
Main Methods:
- A three-arm feasibility randomized controlled trial (RCT) involving 95 dual-smoker couples (N=190).
- Comparison of two partner-involved FITs (single vs. dual incentives) against a no-treatment control.
- Offered nicotine replacement and psychoeducation to all participants.
Main Results:
- High retention rate (89%) indicates feasibility of dyadic FIT implementation.
- Treatments were highly tolerable for participants (p < .001).
- Preliminary efficacy showed promise for partner-involved FITs (OR = 2.36-13.06).
Conclusions:
- Dyadic adaptations of financial incentive treatments are feasible and well-tolerated in dual-smoker couples.
- Partner-involved FITs demonstrate potential for improving smoking cessation outcomes in this population.
- Further adequately powered RCTs are warranted to confirm efficacy.

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

01:18Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

01:23Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
203
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
