Guidelines recommend that African Americans know their sickle cell trait status to inform reproductive health decisions. Few studies have applied a behavioral theory to identify factors associated with sickle cell trait screening to inform intervention targets to increase this behavior. We applied a Sickle Cell Trait Screening Framework to identify factors associated with African Americans' intention to ask for sickle cell trait screening. Participants (N = 300), ages 18 to 35, completed a cross-sectional survey. A three-step sequential ordinary least squares regression analysis identified factors influencing intention. Results indicated socio-demographic factors (age, education), knowledge and fear beliefs (screening knowledge, perceived threat), and reasoned action approach (RAA) constructs were associated with intention. RAA constructs influenced intention over knowledge and fear beliefs with an increase in R of .468. Perceived behavioral control was more predictive of intention (β = .576, p < .001). Attitude and perceived norm also had significant weights (β = .325 and β = .192, both p < .001, respectively). Findings from this study can inform strategies (e.g., eliminating costs associated with screening, reducing fear of painful tests) to increase sickle cell trait screening among African Americans. Ultimately, more sickle cell carriers will become aware of their trait status and be able to make informed reproductive health decisions.
指南建议非裔美国人了解自己的镰状细胞性状状态,以便做出生殖健康决策。很少有研究应用行为理论来确定与镰状细胞性状筛查相关的因素,从而为干预目标提供信息,以增加这种行为。我们应用了一个镰状细胞性状筛查框架来确定与非裔美国人要求进行镰状细胞性状筛查的意愿相关的因素。参与者(N = 300)年龄在18至35岁之间,完成了一项横断面调查。三步序贯普通最小二乘法回归分析确定了影响意愿的因素。结果表明,社会人口学因素(年龄、教育程度)、知识和恐惧信念(筛查知识、感知威胁)以及理性行动方法(RAA)结构与意愿相关。RAA结构对意愿的影响超过了知识和恐惧信念,R增加了0.468。感知行为控制对意愿的预测性更强(β = 0.576,p < 0.001)。态度和感知规范也具有显著权重(β分别为0.325和0.192,均p < 0.001)。本研究的结果可为提高非裔美国人镰状细胞性状筛查率的策略(如消除与筛查相关的费用、减少对痛苦检测的恐惧)提供参考。最终,更多的镰状细胞携带者将了解自己的性状状态,并能够做出明智的生殖健康决策。
