Available smoking cessation treatments have shown only modest quit success. Presence of a psychologically based behavioral health condition (PBHC), such as depression, anxiety, or addiction, can impact smoking cessation treatment engagement and quit success; however, the differential effect of treatment engagement on smoking cessation outcomes across smokers with and without a PBHC is unknown. The current study examined the moderating effect presence (versus absence) of a PBHC on the relation between treatment attendance and early smoking abstinence following a 4-session smoking cessation treatment. Participants included 529 (45.9% male; Mage = 38.23 years, SD = 13.56; 75.4% White) smokers enrolled in a large randomized controlled trial evaluating the efficacy of a transdiagnostic smoking cessation treatment. A repeated-measures latent class analysis (RMLCA) was conducted to examine treatment attendance. The effects of treatment attendance, PBHC (present/absent), and their interaction were modeled on biochemically-verified point prevalence abstinence using a latent growth curve from 1-week to 1-month post-quit. The RMLCA provided evidence for three classes: Drop-outs (n = 197), Titrators (n = 89), and Completers (n = 243). A significant interaction emerged such that Completers without a PBHC were significantly more likely to be abstinent relative to Completers with a PBHC (b = 2.69, SE = 0.67, p < .001) and Titrators without a PBHC (b = 3.36, SE = 0.80, p < .001). These results provide novel data that implicate the clinical importance of treatment attendance and PBHC status on smoking abstinence.
现有的戒烟治疗方法仅显示出适度的戒烟成功率。存在基于心理的行为健康状况（PBHC），如抑郁、焦虑或成瘾，可能会影响戒烟治疗的参与度和戒烟成功率；然而，在有和没有 PBHC 的吸烟者中，治疗参与度对戒烟结果的差异影响尚不清楚。本研究考察了 PBHC 的存在（有/无）对 4 节戒烟治疗后治疗出勤率与早期吸烟戒断之间关系的调节作用。参与者包括 529 名（45.9%为男性；Mage=38.23 岁，SD=13.56；75.4%为白人）吸烟者，他们参加了一项大型随机对照试验，评估了一种跨诊断戒烟治疗的疗效。采用重复测量潜在类别分析（RMLCA）来检验治疗出勤率。使用从戒烟后 1 周到 1 个月的生化验证点患病率，采用潜在增长曲线模型来检验治疗出勤率、PBHC（有/无）及其交互作用的效果。RMLCA 提供了三个类别的证据：辍学者（n=197）、滴定者（n=89）和完成者（n=243）。出现了一个显著的交互作用，即没有 PBHC 的完成者与有 PBHC 的完成者（b=2.69，SE=0.67，p<0.001）和没有 PBHC 的滴定者相比，更有可能戒烟（b=3.36，SE=0.80，p<0.001）。这些结果提供了新的数据，表明治疗出勤率和 PBHC 状况对吸烟戒断的临床重要性。
