Escala de Necessidade de Pertença: Evidências de Qualidade Psicométrica.

The need to belong represents a motivation of the human being to establish intense and long-term relationships, and it is an important aspect for the maintenance of people's well-being and mental health. Considering the relevance of this construct, we sought to validate the Need to Belong Scale (NBS) for the Brazilian context in three studies (N = 642). The first and second studies aimed to present the factorial structure of this measure through exploratory and confirmatory factor analysis, which confirmed the expected single-factor solution (CFI = 0.96) with the elimination of three items from the original version. The third study sought to present evidence of convergent validity of the NBS, confirming the significant association of this construct with measures of a similar nature (e. g., emotional loneliness). In conclusion, this measure showed to be psychometrically adequate for use in Brazil. [ABSTRACT FROM AUTHOR]
