Psychometric properties of the Spanish version of the abusive supervision scale in ecuadorian working population

Abstract

This study aimed to translate, adapt and analyze the psychometric properties of the Abusive Supervision Scale (Tepper, 2000), Spanish version. Abusive supervision is defined as the sustained display of hostile verbal and nonverbal behaviors, excluding physical contact, from the supervisor to his direct reports. Although the literature has grown in recent years, it was found that there are almost no studies in Ibero-America. The 15-item scale was applied to two groups of workers with a six-month interval (group 1, N=308; group 2, N=283). Different measures were applied in each group and a multiple-group invariance test was carried out. An exploratory and confirmatory factor analysis yielded a one factor solution that explained 49% of the variance and an ordinal alpha of .95. The different measures showed convergent and discriminant validity evidence that was consistent with what was reported in the literature. The findings and their implications are discussed.
