This cross-sectional study examined predictors of skin self-examination (SSE) in a population at increased risk for skin cancer. Subjects were 384 hospital employees participating in a worksite skin cancer screening. Although 61% reported that they performed SSE at least once during the past year, only 20% reported monthly SSE. Only a minority of the subjects were knowledgeable about most of the recommended SSE steps. Based on behavioral self-regulation theory, multivariate analysis showed that a variety of psychological factors (including optimism, knowledge about SSE, perceived self-efficacy, and number of reasons for doing SSE) correlated positively with frequency of SSE. Demographic variables accounted for about 6% of the variance in frequency of SSE. Overall, the variables in this model accounted for about 25% of the variance.
这项横断面研究调查了皮肤癌风险增加人群中皮肤自我检查（SSE）的预测因素。研究对象为384名参与工作场所皮肤癌筛查的医院员工。尽管61%的人报告称在过去一年中至少进行过一次皮肤自我检查，但只有20%的人报告每月进行皮肤自我检查。只有少数受试者了解大多数推荐的皮肤自我检查步骤。基于行为自我调节理论，多变量分析表明，多种心理因素（包括乐观情绪、皮肤自我检查知识、自我效能感以及进行皮肤自我检查的理由数量）与皮肤自我检查频率呈正相关。人口统计学变量占皮肤自我检查频率方差的约6%。总体而言，该模型中的变量占方差的约25%。
