Methods: Self-administered questionnaires were distributed to 321 adults who are above 20 and under 65 years of age. Collected data were analyzed via statistical packages using a multi-group analysis through the SEM (Structural Equation Model). Results: Based on the statistical analysis, stress was a major psychological factor in male subjects. While depression served as a main mediator in female subjects. We discovered that the path coefficients of the following paths showed significant gender differences: mouth dryness → depression, depression → quality of life, stress → quality of life. Conclusions: A gender-specific approach regarding effective prevention of stress and depression may be important for understanding the relationship between mouth dryness and quality of life.
