Abstract

Objective

To validate the Portuguese version of the Children's Sleep Habits Questionnaire (CSHQ-PT) and compare it to the versions from other countries.

Methods

The questionnaire was previously adapted to the Portuguese language according to international guidelines. 500 questionnaires were delivered to the parents of a Portuguese community sample of children aged 2 to 10 years old. 370 (74%) valid questionnaires were obtained, 55 children met exclusion criteria and 315 entered in the validation study.

Results

The CSHQ-PT internal consistency (Cronbach's α) 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 cor-relations, n=58) 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.

Conclusion

The CSHQ-PT evidenced psychometric properties that are comparable to the versions from other countries and adequate for the screening of sleep disturbances in children from 2 to 10 years old.

Resumo

Objetivo

Validar a versão em português do Questionário de Hábitos de Sono das Crianças (CSHQ-PT) e compará-la às versões de outros países.

Métodos

O questionário foi anteriormente adaptado para o português de acordo com as diretrizes internacionais. 500 questionários foram entregues aos pais de uma amostra populacional portuguesa de crianças com idade entre 2 e 10 anos. 370 (74%) questioná- rios válidos foram obtidos, 55 crianças apresentaram critérios de exclusão e 315 foram aceitas no estudo de validação.

Resultados

A consistência interna do CSHQ-PT (α de Cronbach) foi de 0,78 para a escala completa e variou de 0,44 a 0,74 nas subescalas. A confiabilidade teste-reteste das subes- calas (correlações de Pearson, n = 58) variou de 0,59 a 0,85. Nossos dados não foram com- patíveis com a estrutura original de 8 domínios na Análise Fatorial Confirmatória, porém a Análise Fatorial Exploratória extraiu 5 fatores que correspondem a subescalas do CSHQ.

Conclusão

O CSHQ-PT apresentou propriedades psicométricas comparáveis às versões de outros países e adequadas para triagem de problemas do sono em crianças de 2 a 10 anos de idade.
