The regulatory role of sleep quality in the effect of preoperative intrusive thoughts on the fear of pain: structural equation modeling

Key Points

The study aims to examine how sleep quality impacts the relationship between preoperative intrusive thoughts and fear of pain.
Descriptive, cross-sectional design
Included 209 hospitalized patients in the preoperative period
Utilized questionnaires to gather data on pain fear, intrusive thoughts, and sleep quality
Analyzed correlations and predictive relationships through structural equation modeling
Fear of pain negatively correlated with sleep quality (r=-0.172)
Fear of pain positively correlated with preoperative intrusive thoughts (r=0.579)
Sleep quality and intrusive thoughts were predictive of fear of pain
No regulatory role of sleep quality was found in the effect of intrusive thoughts on pain fear

Abstract

To investigate the regulatory role of sleep in the effect of preoperative intrusive thoughts on the fear of pain. A descriptive, cross-sectional study and complying with STROBE guidelines. The study included 209 patients hospitalized in a tertiary hospital during the preoperative period. Data were collected using a Patient Identification Information Form, the Fear of Pain Questionnaire-III, The Preoperative Intrusive Thoughts Inventory (PITI), and the Richards-Campbell Sleep Questionnaire (RCSQ). Female gender and the severity of pain preoperatively were determined to have an effect on the fear of pain and preoperative intrusive thoughts (p 0.05). The preoperative intrusive thoughts of patients and their sleep quality affect the fear of pain. Identifying and controlling the factors affecting the fear of pain will reduce the postoperative pain levels of patients, prevent complications.
