An evaluation of the behavioral inhibition and behavioral activation system (BIS-BAS) model of pain.

This study evaluated the behavioral inhibition and activation system (BIS-BAS) model of pain. Frontal alpha asymmetry (FAA) as a possible neurophysiological correlate of the BIS-BAS was also explored, as was the role of personality factors. Research Method: A cross-sectional study was completed at the University of (The University of Queensland). The sample was N = 69 adults with chronic low back pain. Self-report and data were collected as a part of a treatment outcome study. Correlational analyses were conducted between theorized BIS-BAS-related measures of cognitions (catastrophizing, control beliefs), emotion (depression, anxiety, happiness), and behavior (avoidance, engagement). Correlations and hierarchical regression were used to explore the association between these measures, pain intensity, personality factors, and FAA. Results: As hypothesized, the correlations between the BIS and BAS measures were all negative and mostly significant (ps
