Self-Report Convergent Validity Framework: Preregistration Amendment 1 (Supplement to Exhaustion-Induced Regulatory Transitions in Athletes)

This registration is a pre-specified amendment to an existing preregistration https://osf.io/hk32d/overview?view_only=a577d4b31e5748a6a2541a1ffd209c8f]. It specifies how self-report measures of regulatory capacity (BFI-2-S, ERQ, ACSI-28) and threat appraisal (PFAI-25) are predicted to converge with behavioral outputs from the GGBN Situational Judgment Test. Five confirmatory hypotheses, four falsification criteria, and six sensitivity analyses are specified at N = 22 cross-system data, with no cross-system validation analyses conducted. See attached supplement for complete specification.
