Construct Validity in Evidence-Based Applied Sport Psychology: Integrative Mind–Body Bases of Peak Psychological Performance
The establishment of construct validity in the context of sport psychological assessment and intervention requires the identification of valid functional mind-body origins or bases of athlete psychological responses and associated performance tendencies during training or competition. Finding additional links between heart rate deceleration (HRD) and concomitant brain activity parameters leading up to action that are also associated with performance outcome would be an extension finding in the construct validation process. Irrespective of whether a practitioner subscribes to the Brain-Heart-Mind-Body-Motor (BHMBM) and its interrelated Athlete’s Profile (AP) and Theory of Critical Moments (TCM) models of peak performance, construct validity should be considered when deciding what assessment instrument to use or intervention to apply. The chapter also presents a comprehensive and integrative explication of key components of the Carlstedt Protocol’s (CP) validated athlete assessment and intervention system.
