低收入妇女在医生提供的宫颈癌筛查中占比较少。为妇女提供人乳头状瘤病毒（HPV）自我采样的选择将有助于增加宫颈癌筛查的覆盖率。然而，我们几乎不了解低收入妇女对宫颈癌自采样的态度。我们确定了计划行为理论（TPB）构念与低收入妇女参与HPV自采样意愿之间的关联。在得克萨斯州中部，向从食品银行接受食物援助的妇女进行了一项44项调查。自变量包括TPB的构念（即态度、主观规范和知觉控制）。结果变量为意愿和偏好的自采样。这两个变量均采用了5分制度量。采用层次线性回归模型对数据进行分析。 241名参与者（年龄为50.13 ± 9.60岁）参与了该研究，其中非西班牙裔白人占40％，黑人/非洲裔美国人占27％，西班牙裔占30％。参与者当前完成了子宫颈细胞检测的占54.8％，并偏好自我采样的占42％。参与者的态度和主观规范与自我采样意愿显著相关，解释了38.7％的方差（p < .001）。相比已完成子宫颈细胞检测的妇女，长时间未做子宫颈细胞检测的妇女更有可能偏好自我采样（OR = 1.72，95％CI：1.27，6.04）。低收入妇女自我采样意愿的关键预测因素包括态度和主观规范。未来的研究应该使用TPB作为框架来检查意愿是否预测了低收入妇女的自我采样行为。

Low-income women (LIW) are underrepresented in physician-provided cervical cancer screening. Providing women with an option for Human Papillomavirus (HPV) self-sampling would increase cervical cancer screening. However, little is known about LIW's attitude towards self-sampling for cervical cancer. We determined the associations between the Theory of Planned Behavior (TPB) constructs and LIW intention for participation in the HPV self-sampling.A 44-item survey was administered among women receiving food from a food pantry in central Texas. Independent variables included TPB constructs (i.e., attitudes, subjective norms, and perceived control). The outcome variables were intentions and preference for self-sampling. Both variables were measured on a 5-point scale. Hierarchical linear regression models were used to analyze the data.A sample of 241 participants (age 50.13 ± 9.60 years) comprising non-Hispanic White (40%), Black/African American (27%), and Hispanic (30%) participated in the study. The participants were current with a pap test (54.8%) and preferred self-sampling (42%). The participant's attitudes and subjective norms were significantly associated with their intention for self-sampling, accounting for 38.7% of the variance (p < .001). Women who were overdue for pap testing versus current with pap testing had increased odds of preferring self-sampling (OR = 1.72, 95% CI: 1.27, 6.04).The key predictors for LIW's intention for self-sampling included attitudes and subjective norms. Future research should use the TPB as a framework to examine whether intention predicts self-sampling behavior among LIW.
