摘要

Introduction

The Athens Insomnia Scale (AIS) has shown acceptable performance in face-to-face applications. However, knowledge about AIS performance in online applications could be improved.

Objective

The study aimed to perform confirmatory factor, internal consistency, and differential item functioning analyses of AIS in two Colombian online samples.

Material and methods

Two samples were recruited online at different times (n = 700, M = 37.05, SD = 12.7 and n = 292, M = 60.4, SD = 17.6). Separated confirmatory factor analyses and Cronbach’s alpha and McDonald’s omega were computed for each factor.

Results

The data adjusted better for the AIS two-dimensional model in the general and clinical populations. Excellent internal consistency was observed among the general population sample and clinical sample.

Conclusions

The AIS shows a two-dimensional structure and high internal consistency in two online samples in Colombia. Corroboration of these findings in other samples is necessary.
