Smoking-related diseases (e.g., lung cancer) are the leading cause of mortality in HIV-infected patients. While many PLWH who smoke report a desire to quit, a majority of them have low readiness to quit. This study used logistic and linear regression to examine the relations among two (continuous vs. binary) measures of readiness to quit, smoking cessation self-efficacy (SE), quality of life (QoL), and perceived vulnerability (PV) using baseline data from 100 PLWH who smoke who participated in a clinical trial. Results showed no significant main effects (SE, QoL, and PV) or interaction effects (SE × QoL and SE × PV) on a continuous measure of readiness to quit. However, a follow-up analysis revealed that SE had a curvilinear effect on readiness to quit such that self-efficacy was positively associated with readiness to quit except at the highest levels of self-efficacy where readiness to quit declined. Greater SE significantly increased the likelihood of reporting readiness to quit (yes/no) among those with low QoL or high PV. For PLWH who smoke, improving self-efficacy may increase readiness to quit especially among those with lower quality of life. Psychoeducation tailored to PLWH designed to reduce unrealistic invulnerability to smoking-related diseases along with interventions that target self-efficacy may improve readiness to quit.
吸烟相关疾病（如肺癌）是艾滋病毒感染患者的主要死因。虽然许多吸烟的艾滋病毒感染者表示有戒烟意愿，但其中大多数人戒烟的准备程度较低。本研究使用逻辑回归和线性回归，利用参与一项临床试验的100名吸烟的艾滋病毒感染者的基线数据，检验了两种（连续型与二元型）戒烟准备程度测量指标、戒烟自我效能感（SE）、生活质量（QoL）和感知易感性（PV）之间的关系。结果显示，在连续型戒烟准备程度测量指标上，不存在显著的主效应（SE、QoL和PV）或交互效应（SE×QoL和SE×PV）。然而，一项后续分析表明，SE对戒烟准备程度有曲线效应，即自我效能感与戒烟准备程度呈正相关，但在自我效能感最高水平时，戒烟准备程度会下降。在生活质量低或感知易感性高的人群中，更高的自我效能感显著增加了报告有戒烟准备（是/否）的可能性。对于吸烟的艾滋病毒感染者来说，提高自我效能感可能会增加戒烟准备程度，尤其是在生活质量较低的人群中。针对艾滋病毒感染者量身定制的心理教育，旨在减少对吸烟相关疾病不切实际的无易感性，以及针对自我效能感的干预措施，可能会提高戒烟准备程度。
