The aim of the study was to examine the psychometric properties of the Sickle Cell Self-efficacy Scale (SCSES) in an anonymous, online cohort of adults with sickle cell disease (SCD). The SCSES was completed by 60 adults with SCD. An exploratory factor analysis was conducted. Convergent validity and discriminant validity were assessed using bivariate correlations between the SCSES and other study variables, and internal consistency reliability was evaluated through examining an alpha coefficient. A unidimensional factor structure explained 49.6% of the variance in self-efficacy. The SCSES demonstrated convergent validity and discriminant validity with the select battery of measured concepts and sufficient internal consistency reliability (Cronbach's alpha = .87). The SCSES remains a valid and reliable measure of SCD self-efficacy among adults when used in anonymous, online research.
本研究的目的是在一个匿名的成年镰状细胞病（SCD）在线队列中检验镰状细胞自我效能量表（SCSES）的心理测量特性。60名成年SCD患者完成了SCSES量表。进行了探索性因素分析。通过SCSES与其他研究变量之间的双变量相关性评估收敛效度和区分效度，并通过检查α系数评估内部一致性信度。一个单维因素结构解释了自我效能感中49.6%的方差。SCSES在所选测量概念组中显示出收敛效度和区分效度，以及足够的内部一致性信度（克朗巴赫α系数 = 0.87）。当用于匿名的在线研究时，SCSES仍然是测量成年SCD患者自我效能感的有效且可靠的工具。
