Assessment of Sleep Quality by Questionnaire x Actigraphy

Keywords

sleep quality - sleep quantity - subjective sleep - objective sleep - actigraphy

Introduction: Living in a 24-hour society, despite being comfortable for some, causes a series of health problems for workers. (Moreno CRC, Fisher FM, Rotemberg, L, 2003). One of these problems could be a lack of sleep caused by irregular working hours or alternating work shifts (Facundo LA et al, 2022). Interventions to minimize the problems caused by sleep deprivation are widely publicized in the scientific community, and many of them assess sleep quality through questionnaires. Interventions to minimize the problems caused by sleep deprivation are frequently publicized in the scientific community, and many of them assess sleep quality through questionnaires, with the Pittsburgh Sleep Quality Index (PSQI) being widely used (Araujo PAB et al., 2015; Del Rio Joao, KA et al, 2016). However, people often have a bad perception of their sleep time and can answer the questionnaire wrong.

Aim: This study aimed to analyze the relationship between a subjective assessment (PSQI) and an objective assessment (actigraphy).

Methods: Forty-three workers were recruited from a company with a rotating work shift, and they used an actigraph for 15 days to observe their sleep patterns. After use, they were asked to answer the PSQI questionnaire. Results were compared using Paired Samples T-Test using Jamovi software for Windows version 2.2.5 solid.

Results: There was a significant difference between the sleep quality assessed in the PSQI questionnaire and the actigraphy record (df 41.00 p < 0.01).

Conclusions: Sleep loss and sleep quality are significant variables to be evaluated in sleep research, but in some specific populations, caution and better observation of the application of questionnaires are necessary to assess sleep quality.
