The Acute Recovery and Stress Scale (ARSS) and the Short Recovery and Stress Scale (SRSS) are well-established monitoring tools in German-speaking countries. This study aimed at validating them for English-speaking populations. Overall, 996 athletes (536 males, 24.9 ± 9.1 years) of Australia/New Zealand (n = 380), the United Kingdom (n = 316), and North America (n = 300) participated. The 32-item ARSS consists of eight scales. These scales constitute the eight items of the SRSS with the corresponding ARSS items as descriptors. Confirmatory factor analysis (CFA), internal consistency (α), and discriminatory power of the items (rit) were calculated for the total and subsamples separately. Satisfactory discriminatory power (rit > .30) for all ARSS and SRSS items and acceptable internal consistency (α > .70) was achieved. CFA indicated good fit indices for the total sample and subsamples, and strong measurement invariance was found across subsamples and gender. Correlations between corresponding scales and items (rs = .68 – .78) support theoretical congruency as well as independent usage of both questionnaires. Construct validity of both tools is shown through hypothesis-conforming correlations with the Recovery-Stress Questionnaire for Athletes. Future studies may apply the ARSS and SRSS as monitoring tools in English-speaking regions worldwide.
