Correlations are between the measure (row) assessed at the phase listed in column 5 and the measure (column) assessed at the phase listed in the column title. ***Note. P1 = Phase 1, P2 = Phase 2, VR-36 = Veteran’s Rand-36, PCS = Physical Composite Score (Physical Health Function), MCS= Mental Composite Score (Mental Health Function), SBP=systolic blood pressure mean during three stressor tasks, DBP=diastolic blood pressure mean during three stressor tasks, Δ SBP=systolic blood pressure reactivity during three stressor tasks, Δ DBP=diastolic blood pressure reactivity during three stressor tasks, *= P <.05, **=P<.01 Numbers for P1 include the full sample (maximum N=790) and numbers for P2 are for the subsample with P2 data (maximum N=422).
# indicates a checklist measure, a single item or a variable for which no reliability coefficient can be calculated.
