Denisiievska A. Psychological factors of the subjective quality of sleep in people with interoceptive differences.

The thesis is devoted to a comprehensive analysis of the problem of subjective quality of sleep and the identification of psychological factors that affect the assessment of the quality of sleep in people with interoceptive differences. The results show that there is a difference between people with different levels of interoceptive sensitivity. People with low interoceptive sensitivity have good sleep quality, the lowest severity of dysfunctional thoughts about sleep. As usual, they do not have heavy thoughts before sleep and their rate of insomnia indicates the norm. They also better assess the physical and psychological components of quality of life. The sleep quality of people with a medium level of interoceptive sensitivity is out of normal level, but still average. They also do not have dysfunctional thoughts about sleep. The severity of bedtime thoughts is also average. The level of insomnia is on the verge of normal with mild sleep disorders. People with a medium level of interoceptive sensitivity assess their physical and psychological components of life quality lower than representers from the previous group of sensitivity.
