About this study

Official title: NRT Sampling and Selection to Increase Medication Adherence

To determine the preliminary impact on Nicotine Replacement Therapy (NRT)adherence and examine the underlying mechanisms of action associated with adherence.

Read the detailed description

Adherence is a critical target for successful smoking cessation, with good adherence associated with a three-fold increase in cessation rates relative to poor adherence. Psychoeducational interventions focused on increasing adherence to NRT do not result in behavioral change (e.g., smoking cessation). Experiential approaches, such NRT sampling with practice quit attempts (PQAs), are based on learning theory models of behavioral change and have resulted in increased motivation, self-efficacy, adherence, and abstinence relative to psychoeducation or motivational interventions. However, nicotine sampling still relies of the participant using NRT outside of session, which may not occur. Providing an experiential intervention in which the NRT is sampled and any problems with NRT reframed during the session may provide a powerful learning experience that can increase in home sampling with PQAs and long-term adherence, ultimately increasing the likelihood of smoking cessation. This may be particularly relevant for low-income smokers who hold more negative views of NRT, have lower health literacy, and are less likely to use medication during cessation attempts.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CounselingBehavioural

    Both groups receive smoking cessation counseling although one is focused on medication adherence and addressing barriers to adherence while the other is focused on standard behavioral strategies to quit smoking

  • combination NRTDrug

    Both groups will receive combination NRT to help with smoking cessation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of Participant Retention

    Feasibility of the novel NRT intervention was measured by enrolling the targeted sample size of 80 participants. This outcome measure was also measured by the rate of retention of the participants from baseline to the last study visit after 4 months had passed.

    Measured: From baseline through 4 months

  2. Rate of Recruitment

    The acceptability of the novel NRT intervention was measured by calculating the rate of recruitment of study participants during the 56 weeks of active recruitment and intervention for this study.

    Measured: 56 weeks

  3. Rate of Enrollment

    The acceptability of the novel NRT intervention was measured by calculating the rate of enrollment of study participants during the 56 weeks of active recruitment and intervention for this study.

    Measured: 56 weeks

  4. Treatment Satisfaction

    Treatment satisfaction was measured using the Treatment Satisfaction Survey (TSS), a measure developed in the research lab (i.e. no standardized scoring). The measure included 10 questions about satisfaction with the study treatment that participants rated from 1 (not helpful) to 7 (very helpful). The minimum value for this scale was 10 and the maximum value for this scale was 70, with a total score of 70 indicating greater satisfaction with the study treatment and a score of 10 indicating no satisfaction with the study treatment. Higher scores on this measure indicated better outcomes for the participant since higher scores indicated more satisfaction with the study treatment.

    Measured: 5 weeks

  5. Treatment Satisfaction

    Treatment satisfaction was measured using the Treatment Satisfaction Survey (TSS), a measure developed in the research lab (i.e. no standardized scoring). The measure included 10 questions about satisfaction with the study treatment that participants rated from 1 (not helpful) to 7 (very helpful). The minimum value for this scale was 10 and the maximum value for this scale was 70, with a total score of 70 indicating greater satisfaction with the study treatment and a score of 10 indicating no satisfaction with the study treatment. Higher scores on this measure indicated better outcomes for the participant since higher scores indicated more satisfaction with the study treatment.

    Measured: 13 weeks

  6. Treatment Satisfaction

    Treatment satisfaction was measured using the Treatment Satisfaction Survey (TSS), a measure developed in the research lab (i.e. no standardized scoring). The measure included 10 questions about satisfaction with the study treatment that participants rated from 1 (not helpful) to 7 (very helpful). The minimum value for this scale was 10 and the maximum value for this scale was 70, with a total score of 70 indicating greater satisfaction with the study treatment and a score of 10 indicating no satisfaction with the study treatment. Higher scores on this measure indicated better outcomes for the participant since higher scores indicated more satisfaction with the study treatment.

    Measured: 4 months

  7. Treatment Expectancies at Baseline

    Treatment expectancies were measured using the Treatment Expectations questionnaire, a measure developed in the research lab (i.e. no standardized scoring). This measure included 8 items assessing how useful participants' believed the study treatment would be in helping them quit smoking. Participants rated items 1-5 on a scale from 1 (not at all helpful) to 7 (very much helpful). For items 1-3, participants chose which study treatment they would recommend the most to a friend (i.e. the nicotine patch, nicotine gum, nicotine inhaler, nicotine nasal spray, nicotine lozenge, or none), which study treatment they would recommend least to a friend, and overall, which study treatment they found to be the most useful. Only items 1-5 were analyzed for outcomes, with 35 as the maximum value and 5 as the minimum value. Higher scores indicated higher participant expectations for the study treatment and higher expectations for their treatment outcome.

    Measured: Assessed at baseline

  8. Treatment Credibility

    Treatment credibility was measured using the Credibility and Expectancy Questionnaire (CEQ), which is a standardized measure of treatment credibility and expectancy. CEQ scores were standardized, with the minimum score being -13.5 and the maximum score being 4.43. Higher scores indicated the participant believed the treatment was more credible and had higher expectations for their treatment outcome.

    Measured: 5 weeks

  9. Treatment Credibility

    Treatment credibility was measured using the Credibility and Expectancy Questionnaire (CEQ), which is a standardized measure of treatment credibility and expectancy. CEQ scores were standardized, with the minimum score being -13.5 and the maximum score being 4.43. High scores indicated the participant believed the treatment was more credible and had higher expectations for their treatment outcome.

    Measured: 13 weeks

  10. Treatment Credibility

    Treatment credibility was measured using the Credibility and Expectancy Questionnaire (CEQ), which is a standardized measure of treatment credibility and expectancy. CEQ scores were standardized, with the minimum score being -13.5 and the maximum score being 4.43. High scores indicated the participant believed the treatment was more credible and had higher expectations for their treatment outcome.

    Measured: 4 months

  11. Number of Participants With Medication Adherence at Week 6

    Medication adherence was assessed through self reports from participants and confirmed with package counts by study staff.

    Measured: From baseline through 6 weeks

  12. Number of Participants With Medication Adherence at Week 9

    Medication adherence was assessed through self reports from participants and confirmed with package counts by study staff.

    Measured: From baseline through 9 weeks

  13. Number of Participants With Medication Adherence at Week 13

    Medication adherence was assessed through self reports from participants and confirmed with package counts by study staff.

    Measured: From baseline through 13 weeks
