Objectives:
The Integrated Motivational-Volitional Model (IMV) of Suicide is growing in empirical support. The present study advances IMV research through two aims: (1) to qualitatively probe the subjective experiences of defeat, internal entrapment, and external entrapment, and (2) conducting a 3-month prospective mediation analysis using quantitative and qualitative metrics of defeat and entrapment.
Methods:
The study featured an online two-point survey separated by 3 months. Participants were 255 adults living in the United Kingdom.
Results:
Persons endorsing qualitative defeat and internal entrapment in their narratives also showed higher quantitative scores on corresponding IMV and suicide-related self-report scales. Internal entrapment mediated the effect of baseline defeat on 3-month suicidal ideation, whereas external entrapment mediated the association of baseline defeat on 3-month suicide attempt likelihood. Quantitative assessment of entrapment was more significantly associated with suicide attempts and ideation within mediation tests compared to corresponding qualitative variables.
Conclusions:
IMV model principles are largely supported by findings. Mediation results support further consideration of entrapment and defeat within clinical practice and public health-focused suicide research. Understanding the complexity of entrapment narratives represents an important next step for conducting qualitative IMV-focused research with minoritized and high-risk suicide populations.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
