Depression symptoms significantly predict disability in armed services personnel. Post-traumatic stress and alcohol dependence did not show a significant link to disability in this study.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Military Health

Background:

  • Post-traumatic stress is a significant cause of disability.
  • High comorbidity exists between post-traumatic stress, depression, and alcohol dependence.

Purpose of the Study:

  • To investigate the relationship between post-traumatic stress, depression, alcohol dependence, and disability.
  • To identify predictors of disability in armed services personnel.

Main Methods:

  • Seventy armed services personnel were assessed for DSM-IV diagnoses.
  • Continuous symptom measures for post-traumatic stress, depression, and alcohol dependence were used.
  • Multivariate analysis of variance, analysis of covariance, and multiple regression models were employed to analyze disability predictors.

Main Results:

  • Depression symptoms were a significant predictor of total disability (R²=0.39).
  • No significant interaction was found between diagnostic variables.
  • Post-traumatic stress and alcohol dependence symptoms did not significantly predict disability.

Conclusions:

  • Depression is a key factor contributing to disability in this population.
  • The direct clinical importance of post-traumatic stress in relation to disability warrants further investigation.
