Factors Associated With Sleep Quality in Patients With Chronic Widespread Pain Attending Multidisciplinary Treatment.

Purpose: (1) To investigate the prevalence of poor sleep quality and (2) to explore the associations between clinical, cognitive, and emotional factors and quality of sleep in patients with chronic widespread pain (CWP) receiving multidisciplinary treatment.

Method: Baseline data were used from 163 patients with CWP referred for multidisciplinary treatment. Linear regression models were used to assess the relationship of clinical (pain, fatigue, pain interference, and disability), emotional (anxiety, depression, and psychological distress), and cognitive factors (catastrophizing, acceptance, self-efficacy, kinesiophobia and illness beliefs) with sleep quality, as measured using the Pittsburgh Sleep Quality Index.

Overlap of cognitive concepts in chronic widespread pain: an exploratory study.

Background: A wide variety of cognitive concepts have been shown to play an important role in chronic widespread pain (CWP). Although these concepts are generally considered to be distinct entities, some might in fact be highly overlapping. The objectives of this study were to (i) to establish inter-relationships between self-efficacy, cognitive coping styles, fear-avoidance cognitions and illness beliefs in patients with CWP and (ii) to explore the possibility of a reduction of these cognitions into a more limited number of domains.
