OBJECTIVES: This study aimed to develop a Chinese version of the brief Sleep-Associated Monitoring Index (SAMI-B), and examine its psychometric properties among pregnant women.
METHODS: This cross-sectional study conveniently recruited 665 pregnant women from two tertiary hospitals in Shandong, China; 110 completed a retest survey within two or three weeks after completing the baseline questionnaires. The scale was developed following established guidelines. Participants completed the SAMI-B, SAMI, Insomnia Severity Index, Pittsburgh Sleep Quality Index, Pre-Sleep Arousal Scale, Edinburgh Postnatal Depression Scale, and Generalized Anxiety Disorder-7 Scale. Psychometric evaluation included reliability (internal consistency, test-retest reliability) and validity (construct, item and concurrent validity; and diagnostic accuracy).
RESULTS: The Chinese SAMI-B demonstrated uni-dimensionality construct, appropriate item fit and functioning; acceptable internal consistency (McDonald's ω = 0.917) and test-retest reliability (intraclass correlation = 0.736). It was significantly correlated with the SAMI (correlation coefficient = 0.765，P < 0.001) and other sleep-related measurements (correlation coefficients = 0.412-0.638, Ps < 0.001). The SAMI-B displayed a comparable area under the curve (0.739, 95% CI: 0.703-0.772) with the SAMI in detecting insomnia symptoms. The optimal cutoff point (18) presented a sensitivity of 0.765 and a specificity of 0.615 in distinguishing individuals with and without insomnia symptoms. After controlling for general information, the differences in the SAMI-B scores between those with or without insomnia symptoms remained significant (OR = 1.16, 95% CI: 1.12-1.20).
CONCLUSION: The SAMI-B may be an effective alternative for clinicians and researchers to screen or track vulnerable individuals for prenatal insomnia symptoms.
