Self-management is internationally recognized as important to maintain independence, quality of life and to minimize the risk of poor health outcomes, especially among persons with multi-morbidity. Self-management can be especially challenging for older adults, who have higher rates of multi-morbidity and experience diverse impacts of long-term health conditions on everyday life. Good measures of self-management are currently lacking. The Patient Reported Inventory of Self-Management of Chronic Conditions (PRISM-CC) is a new, generic, multidimensional measure of self-perceived ease or difficulty with self-management, that overcomes many of the limitations of existing measures.
To test the structural validity and test-retest reliability of the Swedish version of the PRISM-CC among seventy-year-olds with long-term health conditions.
Translation of PRISM-CC items into Swedish followed the Patient-Reported Outcome (PRO) Consortium process. Survey data (n = 516 Swedish seventy-year-olds with ≥1 long-term health condition) was used to assess structural validity of the 36-item PRISM-CC using multidimensional item response theory (IRT) models. Test-retest reliability was assessed on a subsample of 58 individuals using intra-class correlation coefficient (ICC) and Bland-Altman Plots.
The Swedish PRISM-CC demonstrated good internal consistency with Cronbach's alpha >0.8 for all domains, and good fit to a graded response IRT model (RMSEA 0.034, SRMSR 0.050, CFI 0.952 and TLI 0.945). All 36 items had standardized loadings >0.7. ICC showed moderate to good test-retest reliability for all seven domains. The Bland-Altman plots showed minimal bias and good test-retest agreement for all domains.
The Swedish PRISM-CC showed good structural validity and test-retest reliability in this sample of relatively healthy seventy-year-olds with long-term health condition(s). Further validation in a population with more severe health issues is needed.
自我管理在国际上被认为对于维持独立性、生活质量以及将健康状况不佳的风险降至最低至关重要，尤其是在患有多种疾病的人群中。自我管理对于老年人来说可能尤其具有挑战性，因为他们患多种疾病的比率更高，并且长期健康状况对日常生活产生多种影响。目前缺乏自我管理的良好衡量指标。慢性病自我管理患者报告量表（PRISM-CC）是一种新的、通用的、多维的自我感知自我管理难易程度的衡量指标，它克服了现有指标的许多局限性。
在患有长期健康状况的70岁老人中测试瑞典版PRISM-CC的结构效度和重测信度。
PRISM-CC项目翻译成瑞典语遵循患者报告结局（PRO）联盟的流程。调查数据（n = 516名患有≥1种长期健康状况的瑞典70岁老人）用于使用多维项目反应理论（IRT）模型评估36项PRISM-CC的结构效度。使用组内相关系数（ICC）和布兰德-奥特曼图对58名个体的子样本评估重测信度。
瑞典版PRISM-CC在所有领域均显示出良好的内部一致性，Cronbach's alpha>0.8，并且与分级反应IRT模型拟合良好（RMSEA 0.034，SRMSR 0.050，CFI 0.952和TLI 0.945）。所有36个项目的标准化载荷>0.7。ICC显示所有七个领域的重测信度为中等至良好。布兰德-奥特曼图显示所有领域的偏差最小且重测一致性良好。
瑞典版PRISM-CC在这个患有长期健康状况的相对健康的70岁老人样本中显示出良好的结构效度和重测信度。需要在健康问题更严重的人群中进行进一步验证。
