The 24-hour sleep patterns interview: a pilot study of validity and feasibility

Area of Science:

• Sleep Medicine
• Psychometrics

Background:

• Accurate measurement of sleep patterns and quality is crucial for understanding sleep disorders and overall health.
• Existing methods for assessing sleep continuity and quality can be resource-intensive.

Purpose of the Study:

• To evaluate the validity and feasibility of the 24-Hour Sleep Patterns Interview (24-Hour SPI).
• To assess the 24-Hour SPI's ability to measure sleep continuity (bedtime, wake time, sleep onset latency, total sleep time) and sleep quality.

Main Methods:

• Two studies were conducted comparing the 24-Hour SPI against established sleep assessment tools.
• Study 1 (n=154) compared 24-Hour SPI with a 2-week sleep diary.
• Study 2 (n=32) compared 24-Hour SPI with actigraphy, sleep diary, and the Pittsburgh Sleep Quality Index.

Main Results:

• Both studies demonstrated a significant correlation between the 24-Hour SPI and existing measures of sleep patterns and quality.
• Feasibility was supported by high data completion rates and participant feedback.
• The interview effectively captured differences in weekday and weekend sleep patterns.

Conclusions:

• The 24-Hour SPI is a valid and feasible instrument for assessing subjective sleep patterns in research settings.
• It is particularly suitable for researchers with budget constraints or a focus on subjective sleep outcomes.
• Further validation with larger and diverse populations is recommended.
