African Americans develop and die from colorectal cancer (CRC) more than any other racial group in the United States. Perceived barriers to screening (e.g. embarrassment and financial costs) likely exacerbate these disparities. Identifying psychological factors that can reduce the impact of perceived barriers and encourage CRC screening is therefore critical. This study explored whether believing the world is fairer for oneself than in general (personal justice ascendancy) would moderate the impact that perceived barriers have on receptivity to CRC screening.
Four-hundred fifty-seven screening eligible African Americans completed measures of beliefs about justice for self and others, as well as perceived barriers to CRC screening. Participants also completed theory of planned behaviour (TPB) measures of screening receptivity (attitudes, norms, perceived behavioural control and intentions).
Perceived barriers and justice beliefs interacted to predict perceived behavioural control over screening. Perceived barriers were associated with less perceived behavioural control only when personal justice beliefs were low. In turn, perceived behavioural control predicted stronger intentions to obtain CRC screening.
Interactive effects with perceived barriers highlight that strong personal justice beliefs play an important role in CRC screening and could aid in addressing CRC screening disparities among African Americans.
在美国，非裔美国人比其他任何种族群体都更易患上结直肠癌（CRC）并因此死亡。人们认为筛查存在障碍（例如尴尬和经济成本），这可能加剧了这些差异。因此，确定可以减少感知障碍影响并鼓励 CRC 筛查的心理因素至关重要。本研究探讨了一个人是否认为自己所处的世界比一般人更公平（个人正义优势），是否会影响其对 CRC 筛查的接受程度。
457 名符合筛查条件的非裔美国人完成了关于对自己和他人的正义信念以及对 CRC 筛查的感知障碍的测量。参与者还完成了计划行为理论（TPB）的筛查接受度（态度、规范、感知行为控制和意图）的测量。
感知障碍和正义信念相互作用，预测了对筛查的感知行为控制。只有当个人正义信念较低时，感知障碍才与较低的感知行为控制相关。反过来，感知行为控制又预测了更强的获得 CRC 筛查的意愿。
与感知障碍的相互作用突显了强烈的个人正义信念在 CRC 筛查中的重要作用，并有助于解决非裔美国人 CRC 筛查的差异。
