The aim was to analyze the psychometric properties of the Spanish version of the Gain in Alzheimer Care Instrument (GAIN), providing validity evidence based on its internal structure, reliability, item analysis, and relationships with other variables. A sample of 113 informal caregivers of people with dementia completed the GAIN, along with questionnaires assessing burden, general mental health, stress, anxiety, depression, and life satisfaction. Confirmatory factor analysis showed a single-factor structure with adequate fit indices. Reliability of GAIN scores was satisfactory, with McDonald's omega equal to .91. Items yielded adequate homogeneity indices. Validity evidence based on relationships with other variables was provided by positive correlations between GAIN scores and life satisfaction, and negative correlations with burden, general mental health problems, stress, anxiety, and depression. All these correlations were statistically significant, and most of them were of moderate magnitude. The Spanish version of the GAIN has a single-factor structure and satisfactory psychometric properties. It is quick and easy to apply and given the association between GAIN scores and other variables, it may be used to provide information about a caregiver's psychological health status.
目的是分析《阿尔茨海默病护理获益量表》（GAIN）西班牙语版的心理测量特性，基于其内部结构、信度、项目分析以及与其他变量的关系提供效度证据。113名痴呆患者的非正式照料者完成了GAIN量表，以及评估负担、一般心理健康、压力、焦虑、抑郁和生活满意度的问卷。验证性因素分析显示单因素结构，拟合指数良好。GAIN得分的信度令人满意，麦克唐纳ω系数为0.91。各项目的同质性指数良好。基于与其他变量关系的效度证据表现为，GAIN得分与生活满意度呈正相关，与负担、一般心理健康问题、压力、焦虑和抑郁呈负相关。所有这些相关性均具有统计学意义，且大多数为中等程度。GAIN西班牙语版具有单因素结构和令人满意的心理测量特性。它应用快速简便，鉴于GAIN得分与其他变量之间的关联，可用于提供照料者心理健康状况的信息。
