Prevalence, associated factors, and nomogram model of suicidality among incarcerated individuals: a developmental adaptation perspective for targeted prevention strategies.

ABSTRACT:

Background

Suicide remains one of the primary causes of death in people in prison, highlighting the urgent need for effective prevention strategies. This study investigated the prevalence and characteristics of suicidality (suicidal ideation, suicidal planning and suicidal attempts) among incarcerated individuals and examined both distal and proximal associated factors using the developmental adaptation framework. Additionally, three predictive models were constructed to assess suicide risk within this population.

Methods
