Biobehavioral Assessments in BACPAC: Recommendations, Rationale, and Methods.

Area of Science:

• Biobehavioral science
• Pain research
• Clinical trial methodology

Background:

• Chronic low back pain (CLBP) research requires harmonized biobehavioral data collection.
• Existing initiatives provide frameworks for pain assessment and data standards.

Purpose of the Study:

• To evaluate psychosocial, psychophysical, and behavioral domains for CLBP.
• To recommend assessment tools for harmonizing biobehavioral data collection within the BACPAC consortium.

Main Methods:

• Reviewed key initiatives (IMPACTT, NIH Task Force, PROMIS, NeuroQOL) for measure selection.
• Identified five essential domains: pain characteristics, psychosocial/behavioral factors, general psychosocial factors, lifestyle, and social determinants.
• Established best practices for quantitative sensory testing in psychophysical pain processing.

Main Results:

• Recommended specific assessment tools and procedures for biobehavioral data collection in CLBP.
• Defined five core domains for comprehensive assessment in CLBP studies.
• Outlined best practices for psychophysical pain assessment.

Conclusions:

• Standardized biobehavioral data collection is crucial for advancing CLBP research.
• The recommended domains and tools will enhance data comparability and research rigor.
• This framework supports the BACPAC consortium's goals for consistent CLBP research.
