Daily monitoring of temporal trajectories of suicidal ideation predict self-injury: A novel application of patient progress monitoring.
OBJECTIVE
The interpersonal theory of suicide argues that suicidal ideation predicts self-injury. We hypothesized that distinct patterns of suicidal ideation could be identified and these ratings could allow early identification of self-injury.


METHODS
The sample consisted of 562 psychiatric inpatients who reported suicidal ideation.


RESULTS
Latent growth class analysis identified five classes of change in suicidal ideation. Patients who displayed prolonged suicidal ideation could be identified with improved sensitivity (89.66%) and negative predictive power (94%), compared to a model based on routine ratings of suicidality at admission (sensitivity = 50%; negative predictive power = 74%). These patients had a fourfold increased risk of self-injury.


CONCLUSIONS
Daily measurement of suicidal ideation may identify inpatients at risk and inform clinical decision-making.
