Objective: This semiprospective case-control study was performed to investigate the relationship between harmony-seeking personality and the occurrence of prostate cancer.
Methods: Out of 217 consecutive participants admitted to hospital for biopsy, 86 and 81 were classified into the case and control groups, respectively, based on their initial diagnosis and eligibility criteria. The participants answered several questionnaires after admission. The logistic regression model was used for multivariate analyses to assess the association.
Results: "Harmony-seeking personality" was selected as the only psychological variable significantly contributing to the model, while "family history of prostate cancer" as the only somatic variable. "Harmony-seeking" maintained a significant contribution to the model, also including "family history" and even to the model adjusted by "patient prediction of cancer diagnosis" and "prostate-specific antigen" (PSA), probably related to the consequences of the disease.
Conclusion: The harmony-seeking personality could differentiate between groups of men with and without prostate cancer.
