The Distress Tolerance Scale (DTS) was administered at baseline and two-week post-quit assessment visit to assess how participants tolerated, appraised, absorbed and regulated their distress [ 68].
To assess mindfulness, the Frieburg Mindfulness Inventory (FMI) [ 67] was administered at the baseline and post-quit assessment visits to assess the potential acquisition of mindfulness skills as a result of the mindfulness or control intervention.
The Perceived Stress Scale-10 (PSS) was provided to participants at baseline and at the two-week post-quit assessment visit [ 69].
Among these 55 participants, a total of 25 (45%) completed treatment (attended Quit Day Retreat) and testing (two-weeks post-quit assessment visit), including 15 MTS participants and 10 ILS participants.
During a face-to-face MTSO study orientation session, study procedures were described including payment of $30 for attending each of the two face-to-face post-quit assessment visits (at 4 and 24 weeks post-quit attempt).
Failure to provide self-report of no cigarette consumption during the seven days prior to the post-quit assessment visit, or to provide a CO reading of under 7.0 ppm on the breath test, or to attend an assessment visit all resulted in coding as "relapsed".
The PSS provides questions such as "In the last month, how often have you felt that you were unable to control the important things in your life?" and allows for responses on a 5-point Likert scale with 0 = "never" and 4 = "very often" [ 69]. 10) Course Acceptability: A non-validated course evaluation was administered at the 2-week post-quit assessment visit.
The two weeks of post-quit EMA monitoring will closely mirror that used in baseline monitoring, however post-quit assessments will include additional items pertaining to the lapse trigger(s) and the use (if any) of coping mechanisms [ 21].
Instead the primary outcome will be based on a one month assessment of quit rates, with six month quitting variables collected as secondary outcomes.
A Follow-up Smoking Questionnaire will assess the presence and number of 24 h quit attempts since the last assessment, used to calculate presence of at least one quit attempt in the assessment time period.
At the 26-week follow-up assessments, patient quit attempts in the previous 6 months of 24 h or longer were documented.
