An Unpredictable Chronic Mild Stress Protocol for Instigating Depressive Symptoms, Behavioral Changes and Negative Health Outcomes in Rodents

Published on: December 2, 2015

Area of Science:

Psychiatry
Clinical Psychology
Epidemiology

Background:

Growing research interest in personality disorders (PD) and their effect on depression.
Observational studies link PD to poorer social functioning and reduced depression recovery.
Elevated PD rates observed in early-onset and chronic depression subtypes, yet outcome data is limited.

Purpose of the Study:

To investigate the association between personality disorders and remission in early-onset chronic depression.
To identify predictors of remission in this specific depression subtype.

Main Methods:

Analysis of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) database (n=43,093).
Inclusion of respondents aged 18+ from 2001-2002.
Logistic regression used to identify demographic and clinical predictors of remission.

Main Results:

Absence of personality disorders, increased years of education, and being married were significant predictors of remission.
Paranoid personality disorder and obsessive-compulsive disorder were associated with a reduced probability of remission.
Specific PDs like borderline, narcissistic, and schizotypal personality disorders were not assessed.

Conclusions:

Personality disorders are significant predictors of remission in early-onset chronic depression.
Findings suggest PDs influence depression recovery trajectories.
Potential for remission status to bias recall of PD symptoms warrants consideration.
