Background: Few studies have examined the effect of baseline attitudes toward nicotine replacement therapy (NRT) on its actual adherence in a smoking cessation intervention.
Purpose: This study (i) examined the predictability of baseline variables (quantitative data) on NRT adherence and (ii) explored the congruence of participants' statements about NRT products (qualitative data) during counseling sessions with their baseline attitudes.
Methods: This is a mixed-methods research study using a convergent parallel design. Participants included 74 individuals in the treatment group who received behavioral counseling and combination NRT. A Poisson regression analysis was performed to identify baseline variables predicting NRT adherence. Thematic analysis was completed with a subset of participants (n = 38) who varied in NRT attitude scores and adherence. A joint display was created to integrate quantitative and qualitative data and discover convergence.
Results: Approximately 59% of the participants (41/74) used NRT continuously for ≥5 weeks. Having negative attitudes toward NRT and depressive symptoms predicted NRT adherence even after controlling for education and anxiety symptoms. Thematic analysis revealed that NRT adherence is a learning process that consists of the following three distinctive but interrelated phases: (i) information needs, (ii) comprehensive readiness, and (iii) experiential learning. Of the 38 participants, 34 (89.5%) showed convergence between baseline attitude scores and statements about NRT made during counseling sessions.
Conclusions: Individuals who have negative attitudes toward NRT are less likely to use the products in a smoking cessation intervention. Counselors should assess attitudes toward NRT at baseline and address them proactively during counseling sessions.

Few research studies have explored how attitudes toward nicotine substitutes (nicotine patches, gum, and lozenges) affect people’s adherence to those substitutes (using them consistently as directed). This study examined (i) whether age, gender, education, attitudes toward the substitutes, and depressive and anxiety symptoms would predict peoples’ adherence to these nicotine substitutes during a study to help stop smoking and (ii) whether peoples’ statements about their experiences with the substitutes would reveal any patterns. The study was conducted with 74 individuals who received behavioral counseling and combination nicotine substitutes. Having negative attitudes toward the substitutes and depressive symptoms predicted adherence. Age, gender, education, positive attitudes, and anxiety symptoms did not. Statements from a subset of participants (n = 38) revealed that adherence to the substitutes is a learning process that consists of the following three phases: (i) needing more information assuring the safety of the substitutes, (ii) being mentally and situationally ready, and (iii) learning while being involved in the process such as “trial and error.” Individuals who have negative attitudes toward the substitutes are less likely to use them, and counselors should assess attitudes toward nicotine replacement therapy before suggesting their use and address these attitudes proactively during smoking cessation counseling sessions.
