Adaptación y validación de una escala de fuentes de estrés en estudiantes peruanos de odontología

Abstract

Introduction

At the higher education level, dental students face various academic, clinical and personal challenges that can generate high levels of stress, affecting their well-being and performance. Therefore, it is important to have validated instruments to identify and evaluate the main sources of stress.

Materials and methods

Instrumental study with the voluntary participation of 173 students of both sexes of the stomatology course of a private university in Peru. The instrument to be validated was the Dental Environment Stress (DES), made up of 30 items distributed in 4 dimensions. Aiken's V coefficient was used to assess content-based validity, confirmatory factor analysis (CFA) to assess internal structure and Cronbach's Alpha coefficient for reliability.

Results

All items received a favorable evaluation by the judges (V > 0.70). When applying the CFA, adequate goodness-of-fit indices were obtained: χ² = 678.314, p < 0.001, gl = 399, χ²/df = 2.42, CFI = 0.991, TLI = 0.990, RMSEA = 0.052 and SRMR = 0.062, from which, it can be deduced that the model obtained a good fit and it fits well with the data. Finally, the reliability of the total scale and its dimensions was very good (ω > 0.80).

Conclusion

The sources of stress scale demonstrate adequate psychometric properties, therefore, it can be useful for the management of the training of qualified human resources in dentistry.
