OBJECTIVES
We aimed to test the reliability and structural validity (also called dimensionality) of the online Pittsburgh Sleep Quality Index among college students from low-income regions.
METHODS
We assessed 195 Brazilian college students from a low-income region (Gini index of 0.56), of whom 117 were reassessed to evaluate the reliability. We collected all data in a self-reported online twice, 2-week apart. We evaluated reliability and structural validity.
RESULTS
All questionnaire components showed reliability, correlation coefficient ≥0.49. In the structural validity, the confirmatory analysis showed better global model adjustment for the one-factor (RMSEA = 0.019; SRMR = 0.041; CFI = 0.992; TLI = 0.986) solution compared with two-factor (RMSEA = 0.099; SRMR = 0.070; CFI = 0.764; TLI = 0.619) and three-factor (RMSEA = 0.108; SRMR = 0.066; CFI = 0.763; TLI = 0.548) solutions, respectively.
DISCUSSION
The online questionnaire presents acceptable reliability and structural validity in Brazilian low-income regions.
目的
我们旨在测试低收入地区大学生在线匹兹堡睡眠质量指数的信度和结构效度（也称为维度性）。
方法
我们评估了来自低收入地区（基尼系数为0.56）的195名巴西大学生，其中117人接受了重新评估以评估信度。我们通过在线自填方式收集了所有数据，分两次进行，间隔2周。我们评估了信度和结构效度。
结果
所有问卷组件均显示出信度，相关系数≥0.49。在结构效度方面，验证性分析表明，单因素模型（RMSEA = 0.019；SRMR = 0.041；CFI = 0.992；TLI = 0.986）的整体模型拟合优于双因素模型（RMSEA = 0.099；SRMR = 0.070；CFI = 0.764；TLI = 0.619）和三因素模型（RMSEA = 0.108；SRMR = 0.066；CFI = 0.763；TLI = 0.548）。
讨论
在线问卷在巴西低收入地区具有可接受的信度和结构效度。
