Fig. 2. Linear regression examining the association of PTSD and depression with number of health care visits for the high-user group. Solid lines represent statistically significant paths. An indirect effect based on the product of two unstandardized ß weights represents the total association between PTSD and number of visits. PTSD to Medical Conditions: (Direct = .392 + (Indirect) 0 = (Total) .392. PTSD to No. of Health Visits: Indirect = .392 x .488 = .191 (Total).
