Key result
Laboratory stressors elicited significant cardiovascular responses in preschool children, with intensity and variability dimension scores showing modest test-retest reliability (r=0.25-0.50, P>.01).
Population
137 children between the ages of three and five years

CVR assessment in preschoolers warrants clinical caution given modest reliability; leaves open validation of dimensional scores in longitudinal cohorts.
Observational (n=137)
Effect estimate: r=0.25 to 0.50
p-value: p=>.01
Dimensional scores reflecting the intensity and variability of cardiovascular reactivity may achieve greater reliability than traditional difference or residual scores in preschool children.
Boyce et al. (1995) reported an observational. Laboratory stressors (developmentally challenging tasks) was evaluated on Test-retest reliability of cardiovascular reactivity dimension scores (r=0.25 to 0.50, p=>.01). Laboratory stressors elicited significant cardiovascular responses in preschool children, with intensity and variability dimension scores showing modest test-retest reliability (r=0.25-0.50, P>.01).
