The SISCO SV-21 Inventory demonstrated excellent model fit and measurement invariance across sex for assessing academic stress in 551 Peruvian adolescents (mean age 15.34 years).

The SISCO SV-21 is a psychometrically sound and invariant instrument for measuring academic stress in adolescents.
Academic stress is a phenomenon that affects students across multiple domains, and although several psychometric studies have addressed this issue, the adolescent population has received limited attention to analyze the psychometric properties of the SISCO SV-21 The study included 551 Peruvian adolescents (56.4 % female), aged 12 to 17 years ( M = 15.34, SD = 1.50). The SISCO SV-21 Inventory was administered to evaluate academic stress, and data were analyzed to assess its internal structure, reliability, and measurement invariance The three-factor model of the 21-item version showed excellent model fit and high internal consistency, both overall and across each dimension. Measurement invariance across sex was confirmed. Additionally, a network analysis supported the instrument’s convergent validity by demonstrating significant associations between academic stress, emotional exhaustion, sex, and age The SISCO SV-21 is a psychometrically sound instrument for measuring academic stress in adolescents. It demonstrated a strong association with emotional exhaustion and proved to be an invariant measure across sex. Furthermore, the findings revealed that female and younger adolescents reported higher levels of academic stress.
Ramos‐Vera et al. (Sat,) conducted a cross-sectional in Academic stress (n=551). SISCO SV-21 Inventory was evaluated on Internal structure, reliability, and measurement invariance. The SISCO SV-21 Inventory demonstrated excellent model fit and measurement invariance across sex for assessing academic stress in 551 Peruvian adolescents (mean age 15.34 years).
