The Portuguese version of the Children’s Sleep Habits Questionnaire (CSHQ-PT) validation study is now published.
The CSHQ-PT internal consistency (Cronbach’s alpha) was 0.78 for the total scale and ranged from 0.44 to 0.74 for subscales. The test-retest reliability for subscales (Pearson’s correlations ranged from 0.59 to 0.85.
Our data did not adjust to the original 8 domains structure in Confirmatory Factor Analysis but the Exploratory Factor Analysis extracted 5 factors that have correspondence to CSHQ subscales.
Likewise, the CSHQ-PT evidenced psychometric properties that are adequate for the evaluation of the sleep habits and sleep disturbances in children from 2 to 10 years old.
