Functional dyspepsia is a chronic disorder of the upper gastrointestinal tract that anatomical or biochemical abnormalities do not explain it. The purpose of this study was to assess the mediating role of stress, anxiety, and depression in the relationship between personality type D and functional dyspepsia.

In addition, data analysis was performed using Smart PLS software.

Findings:

The findings of the study showed that D personality type directly affects the severity of functional dyspepsia (effect 41%), plus personality type D by mediating depression (31%) and anxiety (21%) on the severity of indigestion has a confidence level of 95%. However, because of the lack of path coefficient between the variables of stress and functional dyspepsia (T-value 96/1), the indirect effect of the D-type variable on the severity of functional dyspepsia was not confirmed with the mediation of stress.
