Abstract

Objective: Youth with type 1 diabetes and their families engage in complex health behaviors to help manage blood glucose levels and to reduce the risk of serious health complications. Given well-documented health disparities in pediatric diabetes, rapid and equitable assessment of diabetes self-care can help identify potential areas where support is needed. This purpose of this study was to (a) develop a short-form of the Self-Care Inventory-Revised (SCI-R) and (b) evaluate validity, reliability, and differential item functioning (DIF) across several socio-illness-demographic variables of the full and short-form SCI-R.

Methods: Participants were 181 adolescent-caregiver dyads from the Predicting Resiliency in Youth with Type 1 Diabetes (PRYDE) study who completed a 15-item version of the SCI-R. Adolescents (age: M = 14.64, SD =1.70, range 12-18 years), identifying as female (n = 92), male (n = 92), Black/AA (57%), and/or White (43%), also completed diabetes-specific measures of stress and Health-related Quality of Life (T1D-HRQoL). Youths' most recent hemoglobin A1c (HbA1c) values were extracted from their medical records.

Results: Initial items selected based on the six highest factor loadings of 15 were evaluated using DIF analyses. The final 6-item youth and caregiver SCI-SF6 totals correlated with HbA1c, stress, and T1D-HRQoL. They were invariant across participant dyads at the scalar level (root mean squared error of approximation =.077, 90% CI: .056-.098; comparative fit index =.971, standardized root mean square residual = .0490). DIF analyses failed to reject the null hypothesis for item bias factor loadings or item thresholds across age, family income, HbA1c, racial category, gender, and illness duration.

Conclusions: The results support initial evidence of equitable assessment, measurement invariance, validity, and reliability for SCI-SF6 across important socio-illness-demographic variables.

在不同种族和收入的1型糖尿病青少年及其照顾者中自我照顾问卷的开发、验证和项目偏差评估

目的：1型糖尿病青少年及其家庭参与复杂的健康行为，以帮助控制血糖水平，降低严重健康并发症的风险。鉴于儿科糖尿病的健康差异有充分的记录，对糖尿病自我保健进行快速和公平的评估可以帮助确定需要支持的潜在领域。本研究的目的是(a)编制一份自我护理量表修订版（SCI-R）的简本，(b)评估完整版和简本SCI-R的几个社会疾病人口统计变量的效度、信度和差异项目功能（DIF）。方法：参与者是来自预测青少年1型糖尿病患者弹性（PRYDE）研究的181名青少年照顾者，他们完成了15项版本的SCI-R。青少年（年龄：M = 14.64, SD =1.70，范围12-18岁），确定为女性（n = 92），男性（n = 92），黑人/AA（57%）和/或白人（43%），也完成了糖尿病特定的压力和健康相关生活质量（T1D-HRQoL）测量。从他们的医疗记录中提取青少年最近的血红蛋白A1c （HbA1c）值。结果：根据15个最高因子负荷的6个选择的初始项目使用DIF分析进行评估。最后6项青少年和照顾者SCI-SF6总分与HbA1c、压力和T1D-HRQoL相关。在标量水平上，它们在参与者双组之间是不变的（近似的均方根误差=）。0.077, 90% ci: 0.056 - 0.098；比较拟合指数=。971，标准化均方根残差= 0.0490)。DIF分析未能拒绝项目偏差因素负荷或项目阈值的零假设，这些因素包括年龄、家庭收入、糖化血红蛋白、种族类别、性别和疾病持续时间。结论：结果支持SCI-SF6在重要的社会疾病-人口变量中公平评估、测量不变性、效度和可靠性的初步证据。
