Associations between Predictors of PTSD and Psychosocial Functioning in Veterans: Results from a Longitudinal Assessment Study

Figure 2

Predictor effects on WHODAS scores. For this figure and Figure 4, depression, social support, and PTSD symptoms are centered and scaled to 1 standard deviation. Alcohol was categorized into a 4-category variable, suicidal ideation a 3-category variable, and sleep a 4-category variable that were fit as continuous variables in the model. The effects on the outcome for each predictor are shown when all other continuous predictors are held at their mean (zero) and alcohol, suicidal ideation, and sleep at their lowest level (zero).
