The relationships among gratitude, self-esteem, depression, and suicidal ideation among undergraduate students.

The main purpose of this study was to examine the relationships among gratitude, self-esteem, depression, and suicidal ideation. In total, 814 undergraduate participants (259 males and 555 females with mean age of 20.13 years) completed four inventories measuring the variables of interest. Analyses of structural equation modeling found that gratitude had direct effects on individuals' self-esteem, depression, and suicidal ideation. In addition, gratitude had indirect effects on individuals' suicidal ideation via self-esteem and depression, and self-esteem had direct effects on individuals' depression. These results support the proposed model of suicidal ideation and contribute to the understanding of how gratitude influences individuals' suicidal ideation via psychological and physical variables.
