Quality of Life and Personality Traits in Dyspepsia Patients and Healthy Individuals: A Case-Control Study

Dyspepsia is a common disorder that puts much socio-economic pressure on patients due to its high prevalence. Various factors can cause this disorder.

This study investigated the relationship between dyspepsia, quality of life, and personality traits.

This case-control study selected 50 people with dyspepsia and 50 healthy people by simple random method. Patients’ demographic information was recorded using a researcher-made checklist. Then, the WHOQOL-BREF questionnaire measured the quality of life, and the NEO-FFI-60 questionnaire assessed personality traits. Finally, the data were analyzed using a chi-square test, independent t-test, and multivariate linear and logistic regression by SPSS software version 22 at the significance level of 0.05.

The mean score of anger was higher in people with dyspepsia than in healthy people (P = 0.000), but other indicators were higher in healthy people than in people with dyspepsia (P < 0.05). Finally, the personality traits of anger, acceptance of new experiences, and conscientiousness had a significant relationship with quality of life in people with dyspepsia (P < 0.05).

Dyspepsia reduces the quality of life and affects the personality traits of individuals. Thus, improving dyspepsia can improve patients’ personality traits and quality of life.
