Summary
The Turkish version of the Psychological Inflexibility in Pain Scale (PIPS) is a valid and reliable tool for assessing psychological inflexibility in chronic pain patients. This validated scale aids in understanding pain management within the Turkish-speaking population.
Area of Science:
- Psychology
- Pain Management
- Psychometrics
Background:
- Chronic pain significantly contributes to disability worldwide.
- Psychological inflexibility is a key factor associated with chronic pain.
- The Psychological Inflexibility in Pain Scale (PIPS) measures this construct.
Purpose of the Study:
- To evaluate the psychometric properties and factor structure of the Turkish version of the PIPS.
- To assess the validity and reliability of the PIPS in Turkish chronic pain patients.
Main Methods:
- 278 Turkish participants with chronic pain completed the PIPS and other psychological measures.
- Exploratory and confirmatory factor analyses were used to determine the scale's structure.
- Reliability (internal consistency, test-retest) and criterion validity were assessed.
Main Results:
- An 11-item, two-factor structure (avoidance and cognitive fusion) demonstrated good psychometric properties.
- The scale showed good internal consistency (α = .883) and strong test-retest reliability (r = .904).
- The PIPS subscales correlated significantly with related constructs like experiential avoidance, cognitive fusion, anxiety, depression, and pain catastrophizing.
Conclusions:
- The Turkish PIPS is a valid and reliable instrument for assessing psychological inflexibility in chronic pain.
- Further research in specific patient groups and varying pain characteristics is recommended.
