To assess the validity and reliability of the Athens Insomnia Scale-8 (AIS-8) among Chinese psychiatric inpatients, addressing a critical gap in cross-cultural insomnia assessment research.
Key Findings:
A two-factor model structure of 'nighttime sleep problems' and 'daytime dysfunction' was identified, suggesting a nuanced understanding of insomnia symptoms.
The item 'daytime sleepiness' had low factor loadings but was necessary for model fit, indicating its relevance in clinical assessments.
Cronbach's alpha for the AIS-8 was 0.84, indicating good reliability, which supports its use in clinical settings.
Significant positive correlations were found between AIS-8 scores and PHQ-9 and GAD-7 scores, supporting convergent validity and highlighting the relationship between insomnia and mental health.
Interpretation:
The AIS-8 shows acceptable reliability and validity in assessing insomnia among Chinese psychiatric inpatients, filling a gap in cross-cultural validation.
Limitations:
The study's geographical scope limits generalizability, suggesting caution in applying findings to other populations.
Sample characteristics may not represent the broader population of psychiatric inpatients, which could affect the applicability of the results.
Conclusion:
The AIS-8 can be considered a reliable tool for clinical insomnia assessment in Chinese psychiatric settings, though further research is needed to confirm its applicability across diverse populations.
