To develop and evaluate the psychometric properties of the Self-Care of Stroke Inventory (SCSI).
A cross-sectional, instrument development and the psychometric testing study was conducted. A 23-item self-report Self-Care of Stroke Inventory with 3 separate scales was developed. This study involved three stages: (a) Initial items generation; (b) Content and face validation; (c) Psychometric properties evaluation. The SCSI was validated by content validity, construct validity, convergent validity, internal consistency, and test-retest reliability.
From the initial 80-item pool, 24 items of 3 scales in the SCSI were retained by the expert consultation and item analysis. The scale's content validity was 0.976, 0.966, and 0.973. The EFA showed the total variance explained by the 3 scales of the SCSI were 73.417%, 74.281%, and 80.207%, respectively. The models of the 3 scales identified by EFA were all confirmed by the CFA. The SCSI scale shows evidence of good convergent validity. Cronbach's αs were 0.830, 0.930, and 0.831. Test-retest reliability of the SCSI was excellent, with an intraclass correlation coefficient of 0.945, 0.907, and 0.837.
The final 23-item SCSI presents good psychometric properties and can be used to explore the self-care of stroke in community settings.IMPLICATIONS FOR REHABILITATIONThis study developed and validated the Self-Care of Stroke Inventory (SCSI).The SCSI contains the following 3 scales: the Self-care Maintenance of Stroke scale, the Self-care Monitoring of Stroke scale, and the Self-care Management of Stroke scaleThe 23-item SCSI demonstrated strong psychometric properties.The SCSI may be used to develop future programmes to promote self-care for stroke survivors and improve their rehabilitation outcomes.
开发并评估卒中自我护理量表（SCSI）的心理测量特性。
进行了一项横断面的量表开发及心理测量测试研究。开发了一个包含23个项目的自评卒中自我护理量表，分为3个独立量表。本研究包括三个阶段：（a）初始项目生成；（b）内容和表面效度验证；（c）心理测量特性评估。通过内容效度、结构效度、收敛效度、内部一致性和重测信度对SCSI进行验证。
从最初的80个项目库中，经过专家咨询和项目分析，保留了SCSI中3个量表的24个项目。量表的内容效度分别为0.976、0.966和0.973。探索性因素分析表明，SCSI的3个量表解释的总方差分别为73.417%、74.281%和80.207%。探索性因素分析确定的3个量表模型均得到验证性因素分析的证实。SCSI量表显示出良好的收敛效度证据。克朗巴哈系数分别为0.830、0.930和0.831。SCSI的重测信度极佳，组内相关系数分别为0.945、0.907和0.837。
最终的23项SCSI具有良好的心理测量特性，可用于探索社区环境中卒中患者的自我护理情况。
对康复的启示
本研究开发并验证了卒中自我护理量表（SCSI）。
SCSI包含以下3个量表：卒中自我护理维持量表、卒中自我护理监测量表和卒中自我护理管理量表。
23项SCSI表现出强大的心理测量特性。
SCSI可用于制定未来促进卒中幸存者自我护理并改善其康复效果的方案。
