Smoking cessation treatment that includes anxiety management effectively reduces self-reported distress intolerance. This reduction in distress intolerance is linked to higher success rates in quitting smoking.
Area of Science:
- Psychology
- Behavioral Science
- Addiction Research
Background:
- Distress intolerance is a known vulnerability factor in smoking maintenance and relapse.
- Previous research has not explored changes in distress intolerance during smoking cessation interventions.
- Understanding these changes is crucial for improving smoking cessation outcomes.
Purpose of the Study:
- To investigate the impact of two smoking cessation interventions on distress intolerance.
- To determine if changes in distress intolerance correlate with smoking cessation success.
- To compare a standard program with one incorporating anxiety management.
Main Methods:
- 384 treatment-seeking smokers were randomized into Standard Cessation Program (SCP) or Smoking Treatment and Anxiety Management Program (STAMP).
- Both programs consisted of 4 sessions, with quit dates aligned with the final session.
- Distress intolerance was measured using the Discomfort Intolerance Scale (DIS) and Breath Holding Duration Task at baseline and weekly.
Main Results:
- The STAMP intervention led to a significantly greater reduction in self-reported distress intolerance (DIS scores) compared to SCP.
- Reductions in DIS scores during treatment mediated the positive effect of STAMP on smoking abstinence at 3 months post-quit.
- No significant differences were observed between groups in changes related to the Breath Holding Duration Task.
Conclusions:
- Self-reported distress intolerance is modifiable through anxiety management-focused smoking cessation treatment.
- Standard smoking cessation treatment did not significantly alter distress intolerance.
- Reducing distress intolerance may be a key mechanism for promoting long-term smoking abstinence.
