Abstract
This study aims to develop a valid and reliable Adversity Response Profile (ARP) instrument specifically designed to measure the Adversity Quotient of junior and senior high school students in a mathematics context. This research employs a Research and Development (R and D) design utilizing the 4D model (Define, Design, Develop, and Disseminate). The instrument construction is grounded in Stoltzs CO2RE dimensions: Control, Origin, Ownership, Reach, and Endurance. The content validity was assessed by expert validators, while the empirical validity and reliability were evaluated through a limited pilot test involving 36 students. The results of the expert validation led to a structural simplification into 20 negative events (40 items), which demonstrated a high content validity index with an Aikens V coefficient more than 0.83. Furthermore, the empirical analysis indicated that all 40 items were valid with correlation coefficients ranging from 0.350 to 0.834 ( more than r table), and the instrument exhibited very high reliability with a Cronbachs Alpha coefficient of 0.947. Based on these findings, the developed ARP instrument is deemed feasible and effective for categorizing students into Quitter, Camper, and Climber levels.
