On the Link Between Emotionally Driven Impulsivity and Aggression: Evidence From a Validation Study on the Dutch...

Area of Science:

• Psychology
• Forensic Psychiatry
• Clinical Psychology

Background:

• The UPPS-P is a promising impulsivity measurement tool.
• Previous validation studies were limited to student groups.
• Forensic psychiatric populations require validated impulsivity measures.

Purpose of the Study:

• To validate the Dutch UPPS-P in a forensic psychiatric sample.
• To assess the UPPS-P's factor structure and internal consistency across diverse groups.
• To explore the relationship between UPPS-P dimensions and self-reported aggression.

Main Methods:

• Confirmatory factor analysis of the Dutch UPPS-P.
• Internal consistency analysis using Cronbach's alpha.
• Comparison of UPPS-P scores across student, community, and forensic psychiatric samples.

Main Results:

• The five-factor structure was supported in combined samples, but not in subsamples.
• High internal consistency was observed for most UPPS-P subscales.
• Negative urgency (NU) significantly predicted self-reported aggression in healthy samples.

Conclusions:

• The Dutch UPPS-P shows potential for use with forensic psychiatric patients.
• Negative urgency is a critical factor in aggression, warranting therapeutic attention.
• Further research with larger forensic samples is needed for robust validation.
