The following is a summary of “Relationship between subjective and objective fatigue and sleep characteristics in individuals with anxiety and mood disorders: An exploratory study,” published in the December 2023 issue of Psychiatry by Stanyte et al.
In people with anxiety and mood disorders (AMD), fatigue and sleep disturbances are prevalent symptoms often gauged through self-report assessments. Their exploratory study delved into the nuanced correlations between subjective and objective measures of fatigue and sleep characteristics within this population. A total of 233 participants (78.5% females, mean age 39.0 years) from a stress-related disorders day care unit took part in this cross-sectional investigation. Utilizing various assessment tools, including Patient Health Questionnaire-9, Generalized Anxiety Disorder-7,
Multidimensional Fatigue Inventory-20, and Pittsburgh Sleep Quality Index, along with the major objective measures such as exercise capacity workload tests and polysomnography monitoring, sought to establish distinct associations between subjective and objective measures. The findings revealed that exercise capacity workload demonstrated links with specific sleep stages, notably lower percentages of stage 1 sleep, REM latency, and wake after sleep onset. Additionally, general and mental fatigue displayed connections with sleep characteristics, linking higher body movements and poorer sleep quality. These results provide valuable insights into the intricate connection between subjective and objective assessments of fatigue and sleep patterns among individuals grappling with anxiety and mood disorders.
