Measuring the occupational balance of people with insomnia in a Chinese population: Preliminary psychometric evidence on the Chinese version of the Occupational Balance Questionnaire.

The sample was a convenience sample from two clinics in one district of Hong Kong, so the results may not apply to other Chinese-speaking populations or settings. The study only provides preliminary evidence that the Chinese questionnaire measures occupational balance; the authors call for larger samples and further factor or Rasch analysis. The original English version suggested more than one factor, while this Chinese version was summarised as one factor, so the underlying structure is not settled. The study did not measure mood or mental well-being, which could affect occupational balance and insomnia. Test-retest reliability was reported for 30 participants, a smaller subgroup than the main sample. This was an assessment validation study, not a treatment study, so it cannot show that improving occupational balance improves insomnia.

The authors declared no potential conflicts of interest and received no financial support for the research, authorship, or publication.

Do not conclude that this questionnaire proves insomnia causes poor occupational balance or that improving occupational balance will improve sleep. It is a preliminary validation study in Chinese-speaking clinic users, and it only shows that lower occupational balance scores were associated with more severe insomnia.
