# Revisiting the Affect Regulation Model of Suicide Ideation: Bidirectional Effects of Momentary Suicide Ideation and Affect

## TL;DR

This study explores how suicide ideation and emotions influence each other over time, suggesting a complex relationship where each can reinforce the other.

## Contribution

The study introduces a dynamic structural equation model to test bidirectional effects of suicide ideation and affect in real time.

## Key findings

- Increases in negative affect and decreases in positive affect were linked to subsequent increases in suicide ideation.
- Increases in suicide ideation were associated with subsequent increases in negative affect and decreases in positive affect.
- Suicide ideation did not moderate the persistence of affect over time, but resolved ideation was linked to reduced distress.

## Abstract

Suicide ideation (SI) may provide relief from negative affect (NA), thereby making future SI more likely through reinforcement processes. Though some studies suggest that SI reduces NA, this evidence is limited and inconclusive.

We used dynamic structural equation models to test whether bidirectional associations between SI and both NA and positive affect (PA) over 2‐h intervals support an affect regulation model of SI. Participants were 140 young adults with SI or suicidal behaviors in the past 4 months who completed a 21‐day ecological momentary assessment with seven daily assessments.

Results demonstrated reciprocal effects over 2‐h intervals, such that within‐person increases in NA and decreases in PA were associated with subsequent increases in SI, and increases in SI were associated with subsequent increases in NA and decreases in PA. The occurrence of SI did not significantly moderate the persistence of NA or PA over 2‐h intervals. However, we replicated prior findings of decreases in affective distress following SI when analysis was restricted to occasions when SI occurred and resolved by the next occasion.

Results suggest that distinct analytic and sampling methods can lead to divergent conclusions regarding whether SI provides relief from affective distress.
