Key result
Type-D personality linked to greater postoperative pain at 12 months following spine surgery.
Why the study?
The study was conducted to investigate the association between Type-D personality and pain-related outcomes in patients undergoing spine surgery, and to discuss implications for managing chronic pain conditions.

Population
200 patients scheduled for elective spine surgery
Comparison

May flag patients for closer pain monitoring after spine surgery; hypothesis-generating for psychosocial screening in elective procedures.
Cohort (n=200)
Does Type-D personality predict worse postoperative pain, recovery, and clinical outcomes in patients undergoing elective spine surgery?
Effect estimate: β = 0.34 (95% CI 0.18-0.52)
p-value: p=0.004
Type-D personality is a significant predictor of worse postoperative pain, slower functional recovery, and lower satisfaction after elective spine surgery, highlighting the need for psychosocial screening.
Riediger et al. (2025) conducted a cohort in elective spine surgery (n=200). Type-D personality vs. non-Type-D patients was evaluated on postoperative pain (VAS) at 12 months (β = 0.34, 95% CI 0.18-0.52, p=0.004). Type-D personality in patients undergoing spine surgery was associated with higher postoperative pain at 12 months compared to non-Type-D patients (β = 0.34; 95% CI 0.18-0.52; p = 0.004).
