Hierarchical Linear Regression

Dependent Variable: Connor-Davidson Resilience Scale (CDRISC) score.

a

5-HTTLPR Genotype: coded as 0 = L′ carrier, 1 = S′S′.

b

TBI Status: coded as 0 = no Traumatic Brain Injury (TBI), 1 = with TBI.

c

Co-Morbidity Factor is the single derived factor score accounting for the high inter-correlation between the PCL-C total score, CES-D total score, and NBSI total score.

d

Community Reintegration of Service Members Instrument - Perceived Limitations in Community Reintegration subscale.
