To evaluate the psychometric characteristics of the Caregiver Preparedness Scale (CPS) in caregivers of stroke survivors.
Caregiver preparedness can have an important impact on both the caregiver and the stroke survivor. The validity and reliability of the CPS has not been tested for the stroke-caregiver population.
We used a cross-sectional design to study a sample of 156 caregivers of stroke survivors. Construct validity of the CPS was evaluated by confirmatory factor analysis (CFA). Internal consistency and test-retest reliability were also evaluated.
Caregivers were, on average, 54 year old (SD = 13.2) and most were women (64.7%). CFA supported the unidimensionality of the scale (comparative fit index = 0.98). Reliability was also supported: item-reliability index and item-total correlations above 0.30; composite reliability index = 0.93; Cronbach's alpha = 0.94; factor score determinacy = 0.97; and test-retest reliability = 0.92.
The CPS is valid and reliable in caregivers of stroke survivors. Scores on this scale may assist health-care providers in identifying caregivers with less preparedness to provide specific interventions.
评估中风幸存者照料者的照料者准备量表（CPS）的心理测量特征。
照料者准备状态对照料者和中风幸存者均可能产生重要影响。CPS的有效性和可靠性尚未在中风幸存者照料者群体中进行测试。
我们采用横断面设计，对156名中风幸存者照料者样本进行研究。通过验证性因素分析（CFA）评估CPS的结构效度。还评估了内部一致性和重测信度。
照料者的平均年龄为54岁（标准差=13.2），大多数为女性（64.7%）。CFA支持该量表的单维度性（比较拟合指数=0.98）。信度也得到了支持：项目信度指数和项目与总分的相关性高于0.30；组合信度指数=0.93；克朗巴哈α系数=0.94；因子得分确定性=0.97；重测信度=0.92。
CPS在中风幸存者照料者中是有效且可靠的。该量表的得分可能有助于医疗保健提供者识别那些准备不足、无法提供特定干预措施的照料者。
