RESUMO
Purpose@#This study investigated levels of economic stress, depression, existential well-being, and family function, and analyzed their influences on suicidal ideation in middle aged adults. @*Methods@#This study included 217 adults aged of 40~65 years. Data were collected from July to August 2019. Data were analyzed separately according to the genders. Descriptive analysis, t-test, Cronbach’s ⍺, Pearson's correlation coefficient, and stepwise multiple regression were conducted using SPSS 23.0 software. @*Results@#The suicidal ideation of the subjects had positive correlations with economic stress and depression but negative correlations with existential well-being and family function. The most significant factor affecting suicidal ideation of middle aged men was depression (β=.68, p<.001), with an overall explanatory power of 46.8%, while the suicidal ideation of middle aged women was substantially affected by depression (β=.53, p<.001), marriage status (β=-.17, p=.028), and presence of chronic diseases (β=.16, p=.030), with an overall explanatory power of 41.6%. @*Conclusion@#The origins of suicidal ideation in middle aged men and women were different. Therefore, suicide prevention plans, nursing interventions, and policies for middle aged adults must consider gender differences.
