Key result
Standard laboratory stress tasks produced highly reliable cardiovascular reactivity within individual tasks (Cronbach's alpha 0.65-0.96), though reactivity was less reliable across different tasks.
Why the study?
Is cardiovascular reactivity to standard laboratory stress tasks internally consistent in adolescents and young adults?
Population
Three large samples of adolescents and young adults (N=326, 136, and 142)
Comparison
Standard laboratory stress tasks vs Rest
Design
Cross-sectional

Within-task CV reactivity reliability supports consistent lab measurement in youth; leaves open cross-task generalizability for clinical or research protocols.
Observational (n=604)
Is cardiovascular reactivity to standard laboratory stress tasks internally consistent in adolescents and young adults?
Effect estimate: alpha 0.65 to 0.96
Cardiovascular reactivity to stress shows high internal consistency within specific tasks but lower consistency across different tasks in adolescents and young adults.
Kelsey et al. (2007) reported an observational. Standard laboratory stress tasks (math, video game, cold pressor) vs. Rest was evaluated on Internal consistency reliability of cardiovascular reactivity within tasks (Cronbach's alpha) (alpha 0.65 to 0.96). Standard laboratory stress tasks produced highly reliable cardiovascular reactivity within individual tasks (Cronbach's alpha 0.65-0.96), though reactivity was less reliable across different tasks.
