Key result
Higher trait anxiety and neuroticism correlate with higher preoperative ASA scores in hip replacement patients.
Why the study?
Preoperative preparation assesses somatic health using scales such as ASA or RCRI, but usually ignores mental functioning despite its influence on health.
Do personality traits and anxiety correlate with preoperative anesthesia risk scales (ASA scale, Lee index) in patients scheduled for hip replacement surgery?

Do personality traits and anxiety correlate with preoperative anesthesia risk scales (ASA scale, Lee index) in patients scheduled for hip replacement surgery?
Personality traits, specifically trait anxiety and neuroticism, significantly correlate with preoperative risk assessment scales including the Revised Cardiac Risk Index (Lee index) in patients undergoing hip replacement surgery.
No immediate practice change indicated; leaves open whether personality assessment refines ASA risk prediction in hip replacement.
Background: Preparing patients for surgery considers assessing the patient’s somatic health, for example by the American Society of Anesthesiology (ASA) scale or the Revised Cardiac Risk Index (RCRI), known as the Lee index. This process usually ignores mental functioning (personality and anxiety), which is known to influence health. The purpose of this study is to analyze the existence of a relationship between personality traits (the Big Five model and trait-anxiety) and anesthesia scales (ASA scale, Lee index) used for the preoperative evaluation of patients. Methods: The study group comprised 102 patients (59 women, 43 men) scheduled for hip replacement surgery. Patients completed two psychological questionnaires: the NEO-FFI (NEO Five Factors Inventory) and the X-2 STAI (State-Trait Anxiety Inventory) sheet. Next, the presence and possible strength of the relationship between personality traits and demographic and medical variables were analyzed using Spearman’s rho rank correlation coefficient. Results: Patients with a high severity of trait anxiety are classified higher on the ASA scale (rs = 0.359; p < 0.001). Neuroticism, defined according to the Big Five model, significantly correlates with scales of preoperative patient assessment: the ASA classification (rs = 0.264; p < 0.001) and the Lee index (rs = 0.202; p = 0.044). A hierarchical regression model was created to test the possibility of predicting ASA scores based on personality. It explained more than 34% of the variance and was a good fit to the data (p < 0.05). The controlled variables of age and gender accounted for more than 23% of the variance. Personality indicators (trait anxiety, neuroticism) additionally accounted for slightly more than 11% of the variance. Trait anxiety (Beta = 0.293) proved to be a better predictor than neuroticism (Beta = 0.054). Conclusions: These results indicate that inclusion of personality screening in the preoperative patient evaluation might help to introduce a more individualized approach to patients, which could result in better surgical outcomes.

Grabowski et al. (2025) conducted a cross-sectional in Patients scheduled for hip replacement surgery (n=102). Personality trait assessment (NEO-FFI and X-2 STAI) was evaluated on Correlation between trait anxiety and ASA scale (rs = 0.359, p=< 0.001). Higher trait anxiety and neuroticism significantly correlated with higher preoperative ASA scale scores (rs=0.359, p<0.001 and rs=0.264, p<0.001, respectively) in hip replacement patients.
