To develop a Cancer Self-Perceived Discrimination Scale (CSPDS) for Chinese cancer patients and to assess its reliability and validity.
A total of 178 patients were recruited and the classical test theory was used to develop the CSPDS. Item analysis was adapted to improve the preliminary version of the CSPDS, then the reliability, the validity and the acceptability of the final version of CSPDS were assessed.
This CSPDS contained 14 items classified into 3 subscales: social withdrawal with 7 items, stigma with 4 and self-deprecation with 3. Good validity (χ/df = 1.216, GFI = 0.935, AGFI = 0.903, I-CVIs> 0.80) and good reliability (Cronbach's alpha = 0.829, Spearman-Brown coefficient = 0.827, test-retest reliability coefficient = 0.944) were found. The completion time was 6.06 ± 1.80 min. Participants who were female and reported poor self-rated health tended to have higher CSPDS scores (P < 0.05).
The results indicated that this CSPDS could be used to assess the level of self-perceived discrimination and to preliminarily screen perceived discrimination among Chinese cancer patients, especially in Southwest China. It may provide a basis for scientific assessment of targeted patient education, psychological counseling, social interventions, and psychotherapy in the future.
为中国癌症患者开发癌症自我感知歧视量表（CSPDS），并评估其信度和效度。
共招募 178 名患者，采用经典测试理论开发 CSPDS。采用项目分析对初步版本的 CSPDS 进行改进，然后评估最终版本的 CSPDS 的信度、效度和可接受性。
该 CSPDS 包含 14 个项目，分为 3 个分量表：社交退缩 7 项、污名 4 项和自我贬低 3 项。具有良好的有效性（χ/df=1.216，GFI=0.935，AGFI=0.903，I-CVIs>0.80）和良好的信度（Cronbach's alpha=0.829，Spearman-Brown 系数=0.827，重测信度系数=0.944）。完成时间为 6.06±1.80 分钟。女性和自我报告健康状况较差的参与者的 CSPDS 评分较高（P<0.05）。
结果表明，该 CSPDS 可用于评估中国癌症患者的自我感知歧视水平，并初步筛查其感知歧视，尤其是在中国西南地区。它可能为未来有针对性的患者教育、心理咨询、社会干预和心理治疗的科学评估提供依据。
