Abstract
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.

The results are presented in the following order: first, the descriptive statistics of the instruments used and the results of the convergent validity of the Single-Item Self-Esteem Scale (SISES); and second, the results of the comparison analysis between the conditions regarding the variation of self-esteem levels
Based on the results of this study, the SISES presented satisfactory psychometric qualities in terms of convergent validity, corresponding to the minimum value recommended for research (Pasquali, 2010)

Studies on self-esteem have been garnering attention in the last several years, as can be observed by typing. The literature shows that to understand/study selfesteem, other variables, such as personality (Bagozzi & Heatherton, 1994; Daly & Wilson, 1983) and prosocial behaviors (Brown & Smart, 1991; Laible, Carlo, & Roesch, 2004), must be considered and the relationship between them tested. Self-esteem: concept and preliminary considerations Self-esteem refers to a set of personal values that is expressed through attitudes an individual harbors toward him/herself and represented by the extremes of self-acceptance or self-rejection, recognition of skills or inabilities, success or failure. Self-esteem is understood as an individual’s sense of self-worth and the evaluation he/she makes of him/herself in terms of his/her competence (Assis & Avanci, 2004). Self-esteem can be summarized into two main dimensions: the sense of being loved and the sense of being capable (Humphreys, 2001)
