Examining optimism and flourishing as protective factors of suicidality across the adult lifespan: A cross-sectional investigation in three Spanish age groups

We examined optimism and flourishing as unique protective predictors of suicidality (viz., suicidal ideation and suicidal behaviors) in a cross-sectional study of young adults (18-35 years), middle-aged adults (36-55 years), and older adults (>= 56 years). Young adults were found to have higher levels of suicidal ideation and suicidal behaviors compared to middle-aged and older adults. Controlling for depressive symptoms, the results of conducting regression analyses consistently implicated flourishing as a distinct predictor of lower suicidal ideation and suicidal behaviors in young adults and middle-aged adults. However, for older adults, only optimism was found to be a unique predictor of lower suicidal ideation and suicidal behaviors. Implications of the present findings for understanding the differential role of optimism and flourishing in accounting for suicidality across the adult lifespan are discussed.
