phD thesis

Persons at risk during interrogations in police custody

Different perspectives on vulnerable suspects

My PhD thesis addresses the prevalence of psychological vulnerabilities in police suspects. In addition, police interrogations of vulnerable suspects and the influence of police detention center environments on suspects are explored.

This was the first (exploratory) research on these subjects in the Netherlands.
