Abstract

Objective

The purpose of the study was to develop and validate the psychometric properties of the Colorectal Cancer and Colonoscopy Screening Health Beliefs Scale for First-Degree Relatives (CCHBS-FDR) instrument for the first-degree relatives (FDRs) of people with colorectal cancer (CRC) in China.

Methods

This study was conducted in two phases: scale development and psychometric testing. In the scale development phase, a preliminary item pool was established based on a systematic review, qualitative interviews (n = 42), and the Revised Colorectal Cancer Perception and Screening (RCRCPS) instrument. The scale was then refined through expert consultation and laymen review. Psychometric properties were tested by item analysis, validity assessment and reliability evaluation on a convenience sample of 258 Chinese FDRs of patients with CRC.

Results

A preliminary 37-item scale with six dimensions, perceived severity, perceived susceptibility, perceived benefits, barriers-priority, barriers-concerns and barriers-knowledge, was developed in the first phase. The content validity index of the CCHBS-FDR was satisfactory (I-CVI = 0.86–1, S-CVI/UA = 0.89, S-CVI/Ave = 0.98). Cronbach's α coefficient for overall scale was 0.863, and subscales ranged from 0.689 to 0.939. Confirmatory factor analysis results suggested that the CCHBS-FDR conformed to the six-factor model (χ²/df = 2.075, RMSEA = 0.065, CFI = 0.892, TLI = 0.880, and SRMR = 0.077).

Conclusions

The CCHBS-FDR demonstrated acceptable reliability and validity as a culturally specific instrument for assessing health beliefs among FDRs with CRC. It can serve as a valuable tool for providing a more precise assessment of health beliefs and helping healthcare professionals develop and evaluate tailored communication interventions to promote colonoscopy screening among FDRs.

中国结直肠癌患者一级亲属结直肠癌和结肠镜筛查健康信念量表（CCHBS-FDR）的编制与验证

目的开发并验证中国结直肠癌患者一级亲属筛查健康信念量表（CCHBS-FDR）的心理测量特性。方法本研究分量表编制和心理测试两个阶段进行。在量表开发阶段，基于系统综述、定性访谈（n = 42）和修订的结直肠癌感知和筛查（RCRCPS）工具，建立了初步的项目库。然后通过专家咨询和外行审查来完善量表。采用项目分析、效度评估和信度评估对258份中国结直肠癌患者的心理测量特性进行检验。结果第一阶段初步编制了一份37题量表，包括感知严重性、感知易感性、感知利益、感知障碍优先、感知障碍关注和感知障碍知识6个维度。CCHBS-FDR的内容效度指标令人满意（I-CVI = 0.86-1, S-CVI/UA = 0.89, S-CVI/Ave = 0.98）。总量表的Cronbach’s α系数为0.863，子量表的Cronbach’s α系数为0.689 ~ 0.939。验证性因子分析结果显示，CCHBS-FDR符合六因素模型（χ2/df = 2.075, RMSEA = 0.065, CFI = 0.892, TLI = 0.880, SRMR = 0.077）。结论CCHBS-FDR作为一种文化特异性的评估CRC患者健康信念的工具，具有可接受的信度和效度。它可以作为一种有价值的工具，提供更精确的健康信念评估，并帮助保健专业人员开发和评估量身定制的沟通干预措施，以促进fdr的结肠镜检查。
