- Abstract
Background: It is important to know predictors of long-term course over time of suicidal thoughts and ideation in depressed older persons., Methods: In this study, 378 depressed older persons were interviewed at baseline, and after 2 and 6 years to evaluate the presence of depressive disorder. The Inventory of Depressive Symptomatology (IDS) was administered every 6 months for 6 years. Latent Class Growth Analysis was performed on the IDS item on suicidal ideation to identify subgroups with different trajectories., Results: Five subgroups with suicidal ideation trajectories were identified: 1) severe, transient (10.9 %), 2) severe, persisting (8.0 %), 3) mild, but increasing (14.9 %), 4) moderate, persisting (35.6 %), and 5) no thoughts (30.6 %). Mixed model analysis showed that trajectories were related to 6-year course of depressive symptoms. Yet, suicidal ideation or thoughts of loss of meaning of life were still present in 22.7 % and 17.4 % of those who remitted after 2 and 6 years. Independent of baseline depressive symptom severity, loneliness, childhood trauma, history of suicidal ideation or attempt, openness to experience, earlier age of depression onset, anxiety symptom severity and worse mastery predicted worse trajectories., Limitations: 47 % dropped out at 6-years follow-up, we did not distinguish between thoughts of death and suicide, we did not assess death by suicide., Conclusions: Although trajectories of suicidal ideation and thoughts of loss of meaning of life were strongly related to the course of depression severity, they also appear after remission. Clinicians should be vigilant for suicidal ideation or death wish, even after remission of depression., Competing Interests: Declaration of competing interest None., (Copyright © 2024.
