STUDY DESIGN
Validation cross-sectional study.
OBJECTIVES
To develop and assess the psychometric properties of two instruments based on the middle-range theory of self-care in chronic illness: the Self-Care in Spinal Cord Injuries Inventory (SC-SCII) and the Self-Care Self-Efficacy Scale in Spinal Cord Injuries (SCSES-SCI).
SETTING
Multicenter study in five spinal units across Italy and Ireland.
METHODS
Instrument development was based on self-care behaviours identified in the scientific literature. Behaviours were grouped into four dimensions during a consensus conference: self-care maintenance, self-care monitoring, self-care management and self-care self-efficacy. Sixty-seven items were subsequently generated based on these dimensions. A multidisciplinary group of 40 experts evaluated content validity. Dimensionality of the final items was tested by confirmatory factor analyses (CFA) with a sample of 318 participants. Internal consistency and test-retest reliability were evaluated for each dimension. Construct validity was assessed using correlations between items and scoring differences amongst participants with more severe conditions and secondary complications.
RESULTS
Content validity of the SC-SCII and SCSES-SCI was satisfactory for thirty-five of the previously generated items, which were further refined. CFA showed comparative fit indexes ranging from 0.94 to 0.97 and root mean square errors of approximation from 0.03 to 0.07. Internal consistency ranged from 0.71 to 0.85, and intraclass correlation coefficients were higher than 0.70. Correlations among dimensions were moderate, and the theoretical hypotheses formulated when designing the instruments were largely confirmed.
CONCLUSIONS
The SC-SCII and the SCSES-SCI represent valid and reliable theoretically-grounded instruments to assess self-care in people with spinal cord injury.
研究设计
验证性横断面研究。
目的
基于慢性病自我护理的中程理论，开发并评估两种工具的心理测量特性：脊髓损伤自我护理量表（SC-SCII）和脊髓损伤自我护理自我效能量表（SCSES-SCI）。
设置
意大利和爱尔兰五家脊髓单位的多中心研究。
方法
仪器的开发基于文献中确定的自我护理行为。行为在共识会议上分为四个维度：自我护理维持、自我护理监测、自我护理管理和自我护理自我效能。随后根据这些维度生成了 67 个项目。一个由 40 名专家组成的多学科小组评估了内容的有效性。最终项目的维度通过 318 名参与者的验证性因子分析（CFA）进行测试。对每个维度进行内部一致性和重测信度评估。通过与病情更严重的参与者和继发性并发症的项目得分差异来评估结构有效性。
结果
SC-SCII 和 SCSES-SCI 的内容有效性对于之前生成的 35 个项目是令人满意的，这些项目进一步得到了完善。CFA 显示，比较拟合指数范围从 0.94 到 0.97，均方根误差从 0.03 到 0.07。内部一致性范围从 0.71 到 0.85，组内相关系数高于 0.70。维度之间的相关性为中度，设计仪器时提出的理论假设在很大程度上得到了验证。
结论
SC-SCII 和 SCSES-SCI 是评估脊髓损伤患者自我护理的有效且可靠的、具有理论基础的工具。
