Single-Item Self-Esteem Scale: Brazilian Adaptation and Relationship with Personality and Prosocial Behavior

Abstract The objective of this correlational study was to test the psychometric properties of convergent validity of the Single-Item Self-Esteem Scale (SISES). The correlation between the SISES and the Rosenberg Self-Esteem Scale (RSE), which also measures self-esteem, and with scales that measure other variables (personality and prosocial behaviors) was also tested. A total of 203 students, aged 18 to 58 years (M=23.49, SD= 5.84), from public and private universities in the city of João Pessoa, participated in the study. The Pro-Socialness Scale (PSS), the Ten-Item Personality Inventory (TIPI), the SISES, the RSE, and a demographic questionnaire were used. The results showed that the Portuguese version of the SISES presents satisfactory validity. Therefore, as this study shows a correlation between self-esteem and personality traits and socio-demographic variables, it contributes to the scientific literature in this field and provides an alternative for measuring self-esteem.
