Health literacy is crucial in shaping health outcomes for individuals with polycystic ovary syndrome (PCOS), influencing their disease perceptions, treatment adherence, and self-management behaviors. Women with PCOS often face challenges due to inadequate health literacy, leading to delayed diagnosis and low treatment compliance. However, there is a lack of specific tools to measure health literacy within the context of PCOS, hindering accurate assessments and targeted interventions.
To address this gap, a health literacy scale for women with PCOS (HL-PCO) was developed and validated. The initial items were generated through a comprehensive literature review, in-depth interviews, and the Delphi method. A cross-sectional validation study was conducted at a tertiary hospital in Changsha, China, using classical test theory (CTT) and item response theory (IRT) for item selection. Reliability was assessed using Cronbach's α coefficient and split-half reliability, while validity was evaluated through various analyses.
The HL-PCO scale retained 17 items across four factors: Acquisition, Understanding, Appraisal, and Application. Confirmatory factor analysis exhibited acceptable goodness-of-fit indices, and the Item Content Validity Index values surpassed 0.833. Robust results were also demonstrated through analyses of convergent validity, discriminant validity, and concurrent validity. The Cronbach's α coefficient for the HL-PCO was 0.930, and the split-half reliability coefficient amounted to 0.836.
The refined HL-PCO scale, comprising 17 items across four factors, has been rigorously validated as a reliable instrument. Its implementation has the potential to enhance health literacy assessment and improvement among women with PCOS, facilitating more effective health education interventions and ultimately improving patient outcomes.
健康素养对于多囊卵巢综合征（PCOS）患者的健康结局形成至关重要，会影响他们对疾病的认知、治疗依从性和自我管理行为。PCOS女性由于健康素养不足常常面临挑战，导致诊断延迟和治疗依从性低。然而，在PCOS背景下缺乏测量健康素养的特定工具，这阻碍了准确评估和针对性干预。
为填补这一空白，开发并验证了一种针对PCOS女性的健康素养量表（HL-PCO）。初始条目通过全面的文献综述、深入访谈和德尔菲法生成。在中国长沙的一家三级医院进行了横断面验证研究，使用经典测试理论（CTT）和项目反应理论（IRT）进行条目筛选。使用Cronbach's α系数和分半信度评估信度，同时通过各种分析评估效度。
HL-PCO量表在四个因素（获取、理解、评估和应用）中保留了17个条目。验证性因素分析显示出可接受的拟合优度指标，且条目内容效度指数值超过0.833。通过收敛效度、区分效度和同时效度分析也得出了稳健的结果。HL-PCO的Cronbach's α系数为0.930，分半信度系数为0.836。
经过完善的HL-PCO量表由四个因素中的17个条目组成，已被严格验证为一种可靠的工具。其应用有可能提高PCOS女性的健康素养评估和改善水平，促进更有效的健康教育干预，最终改善患者结局。
