Behavioral Pain Scale - translation, reliability, and validity in a Swedish context

Area of Science:

• Critical Care Medicine
• Pain Assessment
• Nursing Research

Background:

• Assessing pain in critically ill patients is challenging due to limited communication from intubation and sedation.
• International guidelines recommend behavioral pain assessment tools for non-communicative patients.
• The Behavioral Pain Scale (BPS) is an internationally recognized instrument for this purpose.

Purpose of the Study:

• To translate and adapt the Behavioral Pain Scale (BPS) into Swedish for use in intensive care units (ICUs).
• To evaluate the inter-rater reliability and discriminant validity of the Swedish BPS version.
• To assess the tool's applicability for both intubated and non-intubated critically ill patients.

Main Methods:

• A ten-step translation and adaptation process was used to create the Swedish BPS.
• The adapted Swedish BPS was tested on 20 critically ill patients (10 intubated, 10 non-intubated).
• Inter-rater reliability and discriminant validity were assessed by comparing scores at rest and after repositioning.

Main Results:

• The Swedish BPS demonstrated good inter-rater reliability with 85% agreement in the study sample.
• The instrument showed discriminant validity, distinguishing pain levels between rest and post-procedure assessments.
• The results support the utility of the Swedish BPS in clinical practice.

Conclusions:

• The Swedish version of the BPS is a reliable and valid tool for assessing pain in critically ill patients unable to self-report.
• Further research is recommended to explore the tool's reliability and validity further within the Swedish ICU context.
• The validated Swedish BPS can improve pain management strategies for non-communicative ICU patients.
