How grit mediates depressive symptoms with life and job satisfaction in full-time employed adults with congenital heart disease.

Background: Technological advancements have extended the lifespan of individuals with congenital heart disease (CHD), but physical and mental health issues can affect their life and job satisfaction.

Aims: This study examined whether grit can protect full-time employed adults with CHD from depression by exploring its mediating role between depressive symptoms and life or job satisfaction.

Methods: A cross-sectional design involved 181 adults with CHD assessed using the Patient Health Questionnaire, Grit-10, Satisfaction with Life Scale, and Basic Psychological Need Satisfaction at Work Scale. Data analysis was conducted with SPSS and Smart PLS software for partial least squares structural equation modeling, adhering to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

Results: Indicated that depressive symptoms were negatively correlated with grit, life satisfaction, and job satisfaction, while grit was positively correlated with both satisfaction measures. Grit partially mediated the relationship between depressive symptoms and life/job satisfaction, accounting for 30.70 % and 29.11 % of the variance, respectively.

Conclusions: Grit significantly mitigates the negative impact of depressive symptoms on life and job satisfaction in full-time employed adults with CHD. Nurses should identify signs of depression in adults with CHD and evaluate their grit levels. Interventions to increase grit and reduce depressive symptoms could enhance life and job satisfaction.
