Dependent personality disorder: comparing an expert generated and empirically derived five-factor model personality...

Area of Science:

• Psychology
• Psychiatry
• Personality Disorders

Background:

• The five-factor model (FFM) shows promise for assessing personality disorders (PDs).
• Expert-generated FFM profiles for DSM-IV PDs may have limitations.
• The FFM Dependent Personality Disorder (DPD) profile may be misspecified.

Purpose of the Study:

• To conduct a meta-analytic review of FFM facets and DPD.
• To create a revised, empirically-based FFM DPD profile and count.
• To evaluate the revised FFM DPD profile's correlation with diagnostic and comorbidity measures.

Main Methods:

• Meta-analytic review of studies examining FFM facets and DPD.
• Development of a revised FFM DPD profile and count based on meta-analytic results.
• Correlation analysis with DSM-IV and non-DSM conceptualizations of maladaptive dependency.

Main Results:

• The revised FFM DPD profile and count demonstrated stronger correlations with maladaptive dependency measures.
• The revised FFM DPD profile successfully replicated typical comorbidity patterns found with DSM-IV DPD measures.
• Discrepancies between expert-generated and meta-analytic FFM DPD profiles were identified.

Conclusions:

• An empirically-based FFM DPD profile offers improved assessment of DPD.
• The revised FFM DPD profile enhances understanding of DPD's relationship with other conditions.
• Meta-analytic data provides a more accurate FFM representation of DPD compared to expert consensus.
