Structure and factorial invariance of SISCO SV-21 inventory for the study of academic stress in Peruvian adolescents

Abstract

Background

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

Objective

to analyze the psychometric properties of the SISCO SV-21

Methods

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

Results

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

Conclusion

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.
