Mental disorders in the general population are associated with increased risk of suicidality, but less is known about the independent predictive ability of self‐reported psychological symptoms. We followed 49,321 screened and interviewed Swedish conscripts through 36‐year follow‐up to test whether psychological symptoms predicted suicide and hospitalization for suicide attempts. There were 619 suicides and 1,230 suicide attempts during the follow‐up period. After excluding subjects with any psychiatric diagnoses (n = 5,691, 12%) and controlling for other psychological symptoms, severe symptoms of anger, trouble falling asleep, and feeling down predicted suicide. Similarly anger, headaches, feeling down, and nervousness predicted suicide attempt. Self‐reported psychological symptoms may have a predictive value beyond psychiatric diagnosis.
