Drawing on the Transactional Model and the Interactive Model of Human Adaptation to Stress, this paper presents a battery of instruments designed to comprehensively assess university students’ adaptation to stress. Methods: Data were collected from two academic years, using two independent samples of students: a calibration sample (n = 561) and a validation sample (n = 370) to test the psychometric properties of the instruments. The evaluation protocol included the Stress Questionnaire for Students (SQS), the Primary and Secondary Cognitive Appraisal Scale (PSCAS), the Reduced Coping Inventory (Coping-R), and the Academic Achievement Expectations (AAE). Results: Psychometric validation analyses indicated the best versions of the instruments’ battery. Namely, an 18-item version and a six-factor structure for the SQS, a 10-item version and a five-factor structure for the PSCAS, a 12-item version and a four-factor structure for the Coping-R, and a five-item, one-factor structure for the AAE. Conclusions: The proposed instruments can serve as a compound resource for screening for academic stress experiences in university students, and as an original tool to understand the entire process of stress adaptation.engAcademic stressCognitive appraisalCopingAcademic achievement expectationsHigher education studentsEvaluating how university students adapt to stress: psychometric validation of a psychological instruments batteryresearch article10.3390/epidemiologia7020049
