Personality and Coming to Terms with Cancer: A Cross-Sectional Study of Five-Factor Traits and Illness Acceptance in Oncology Outpatients.

Background/

Objectives

A cancer diagnosis forces a rapid, often unwelcome reorganization of a patient's sense of self, routines, and future plans, and patients vary considerably in how far they progress toward accepting that new reality. Personality is a candidate explanation for this variability, and although the Five-Factor Model has been linked to cancer-related distress and coping in several large cohorts, its relationship to illness acceptance specifically, alongside disease duration, treatment self-assessment, and perceived social support, has not been jointly examined in a single, diagnostically broad oncology sample.

Methods

We surveyed 114 outpatients with a confirmed malignant tumor diagnosis, combining a study-specific questionnaire with the NEO-Five-Factor Inventory (NEO-FFI) and the Acceptance of Illness Scale (AIS). Because several study variables were non-normally distributed and the study-specific measures were ordinal, associations were examined using Spearman's correlation, the Kruskal-Wallis H test, and the Mann-Whitney U test.

Results

Illness acceptance was moderate on average (mean [M] = 26.55, standard deviation [SD] = 7.34); 22 patients (19.30%) were classified as having low acceptance, 76 (66.67%) as average acceptance, and 16 (14.04%) as high acceptance. All five personality domains correlated with acceptance, led by a strong negative association with neuroticism (ρ = -0.632, p < 0.001) and moderate positive associations with extraversion, agreeableness, conscientiousness, and openness to experience (all p < 0.001). Longer disease duration and a more favorable self-rated treatment outcome were both associated with higher acceptance, and patients who felt supported by close relatives scored higher than those who found support difficult to gauge.

Conclusions

Personality traits, particularly neuroticism, were associated with illness acceptance. Brief psychosocial assessment may help identify patients reporting greater difficulties in psychological adjustment to cancer.
