Integrating sleep care in psychological practice: A survey of Brazilian clinical psychologists and a global bibliometric analysis.

Given psychologists' role and the use of psychotherapies for sleep issues, our study explored: (1) whether psychologists inquire about patients' sleep quality and their beliefs regarding the relationship between mental health and biological rhythms, and (2) global trends in psychological approaches through a bibliometric analysis. We analyzed responses from 1011 Brazilian clinical psychologists (October 2018-May 2019) and found that most routinely inquire about sleep quality and address sleep problems, while a small portion did not perceive a direct link between mental disorders and biological rhythms. Behavioral psychotherapy practitioners showed greater interest in sleep quality.

Introduction: The reproductive system is tightly regulated by environmental and physiological signals. Melatonin, known as the hormone of darkness, plays a crucial role in regulating both the circadian and reproductive systems in mammals. Hypothyroidism is a key endocrine disorder that harms the reproductive system.

Familiarity of Brazilian psychologists with basic concepts in sleep science and chronobiology.

Desynchronization of circadian rhythms and sleep-wake patterns impacts biochemical, physiological, and behavioral functions, including mental processes. The complex relationship between circadian rhythms and mental health makes it challenging to determine causality between circadian desynchronization and mental disorders. Regarding the fact that psychologists act as the front line for initial mental health care, we aimed to assess the knowledge and use of sleep science and basic chronobiology by professional psychologists in Brazil.
