Identify which variables are predictors of treatment adherence in cancer patients.
Two hundred twenty cancer outpatients were evaluated by the following instruments: questionnaire on sociodemographic and clinical data, NEO-FFI Personality Inventory Revised (NEO-FFI-R), Multidimensional Health Locus of Control (MHLC) scale, Hospital Anxiety and Depression Scale (HADS), patient's knowledge about cancer disease questionnaire, and Adherence Determinants Questionnaire (ADQ). A logistic regression analysis was applied to verify the predictive power of the variables, and network analyses were conducted through the qgraph package.
The sample was composed of 138 (62.7%) women and 82 (37.3%) men. The mean age of participants was 54.66 (SD = 13.30), and the education level mean was 8.32 (DP = 3.76) years of study. Powerful others locus of control (LOC) and the personality factors conscientiousness and agreeableness are presented as predictors of high treatment adherence. The variable family cancer history, on the other hand, was a predictor of lower adherence levels.
The powerful others LOC may be connected with more trust and dependence in the health team, leading to better adherence. Specific characteristics of personality factors can help individuals to cooperate with their caregivers and to follow medical orders. The evaluated factors are interrelated and should be taken into account by health professionals when developing interventions to modify health-related behaviors and treatment adherence.
确定哪些变量是癌症患者治疗依从性的预测因素。
对 220 名癌症门诊患者进行了以下评估：社会人口学和临床数据问卷、大五人格量表修订版（NEO-FFI-R）、多维健康控制源量表（MHLC）、医院焦虑抑郁量表（HADS）、癌症疾病知识问卷和依从性决定因素问卷（ADQ）。应用逻辑回归分析验证变量的预测能力，并通过 qgraph 包进行网络分析。
样本由 138 名（62.7%）女性和 82 名（37.3%）男性组成。参与者的平均年龄为 54.66（SD=13.30），教育水平平均为 8.32（DP=3.76）年。强力他人控制源（LOC）和人格因素尽责性和宜人性被认为是高治疗依从性的预测因素。另一方面，家庭癌症史这一变量是低依从水平的预测因素。
强力他人 LOC 可能与对医疗团队的更多信任和依赖有关，从而提高依从性。人格因素的特定特征可以帮助个体与他们的照顾者合作，并遵守医疗命令。评估的因素是相互关联的，健康专业人员在制定干预措施以改变与健康相关的行为和治疗依从性时应考虑这些因素。
