Testing hypothesized psychosocial mediators: lessons learned in the MassBUILT study.

Area of Science:

• Occupational Health
• Behavioral Science
• Public Health Interventions

Background:

• Limited formal analysis exists for interventions targeting blue-collar workers' smoking cessation.
• Understanding factors influencing intervention success is crucial for improving cessation rates in this demographic.

Purpose of the Study:

• To examine the role of dual hazard and decisional balance in the MassBUILT smoking cessation intervention for blue-collar workers.
• To determine if changes in these psychosocial variables were associated with smoking cessation.
• To assess if the intervention mediated the relationship between these variables and smoking cessation.

Main Methods:

• Multivariable linear and logistic regressions were employed.
• The study analyzed the association between the intervention and changes in psychosocial variables (dual hazard, decisional balance).
• The study examined the association between increases in psychosocial variables and smoking cessation.

Main Results:

• Higher scores in both dual hazard and decisional balance were significantly associated with smoking cessation, supporting the study's hypothesis.
• The MassBUILT intervention did not significantly alter decisional balance.
• The intervention was found to decrease dual hazard scores.

Conclusions:

• While dual hazard and decisional balance are important predictors of smoking cessation, they were not effectively modified by the MassBUILT intervention.
• The lack of mediation by these psychosocial variables may explain the observed smoking relapse among participants.
• Further research is needed to develop interventions that successfully influence these key factors for sustained smoking cessation in blue-collar workers.
