本研究检验了适用于低收入拉丁裔抑郁症患者临床样本的修订疾病感知问卷的心理测量特性。参与者（N = 339）从公立初级保健中心招募。他们的平均年龄为49.73岁，大多数是墨西哥或中美洲血统的外国出生的女性。采用验证性因子分析对该测度的因子结构进行检验。对结构效度、判别效度和内部一致性进行了评价。由于因子负载量低（< .40）而剔除了3个项目，并明确了7个误差协方差，由24个项目组成的修正模型具有足够的拟合适应度指标和因子负载量，支持结构效度。每个子量表报告了令人满意的内部一致性。5种疾病知觉因素之间的相互关系为这些因素在抑郁症情境下的区别效度提供了初步的支持。这一调整措施的心理测量特性的建立将为未来研究疾病感知在拉丁美洲人寻求帮助和管理抑郁症中的作用铺平道路。
This study examined the psychometric properties of the Revised Illness Perception Questionnaire adapted for a clinical sample of low-income Latinos suffering from depression. Participants (N = 339) were recruited from public primary care centers. Their average age was 49.73 years and the majority was foreign born females of either Mexican or Central American descent. Confirmatory factor analysis was used to test the factor structure of this measure. Construct and discriminant validity and internal consistency were evaluated. After the elimination of three items because of low factor loadings (< .40) and the specification of seven error covariances, a revised model composed of 24 items had adequate goodness-of-fit indices and factor loadings, supporting construct validity. Each of the subscales reported satisfactory internal consistency. Intercorrelations between the 5 illness perception factors provided initial support for the discriminant validity of these factors in the context of depression. The establishment of the psychometric properties of this adapted measure will pave the way for future studies examining the role illness perceptions play in the help seeking and management of depression among Latinos.
