Reliability and validity of the Management of Aggression and Violence Attitude Scale (MAVAS-BR) for use in Brazil

Abstract

Background: Aggression and violent behavior against health care professionals is a serious problem today and has aroused the interest of researchers and authorities. Objective: The purpose of this study was to examine the reliability and validity of the Management of Aggression and Violence Attitude ScaleBrazil (MAVAS-BR) for use with Brazilian nurses. Method: The MAVAS-BR was applied in a convenience sample of 262 nurses, the data were submitted to an exploratory factor analysis, and reliability was estimated using Cronbach's alpha. Results: The MAVAS-BR is composed of 23 items distributed among four factors, and the Cronbach's alpha was σ = 0.75. Discussion: The MAVAS-BR is a reliable instrument for measuring the attitudes of Brazilian nurses facing aggression and violent behavior. The scale has shown to possess validity and the recommended reliability criteria; however, additional studies using this scale should be performed to offer further evidence of its validity in the context of Brazilian nursing.

A Scale for the Management of Aggressive and Violent Behaviour (C_MAVAS): Psychometric Properties Testing in Mental Health Nurses

“…Nurses are arguably the most at-risk group among all the professionals who have to manage patients’ aggression or violence [ 3 , 4 , 6 , 8 , 9 , 10 ]. Psychiatric settings are one of the most frequent health care settings in which violence occurs [ 11 ] and mental health nurses are the most vulnerable group of WPV in psychiatric settings [ 12 ]. However, very few studies over the last decade have examined nurses’ attitudes towards the violence encountered from patients, especially psychiatric in-patients [ 11 , 12 ].…”

“…Quanto menor a pontuação da escala maior é a concordância do sujeito para com o modelo de explicação do comportamento violento, na qual cada item da escala é correspondente. O coeficiente de confiabilidade do MAVAS-BR foi 0,75 (Vargas et al, 2015).…”

“…A MAVAS foi traduzida, adaptada culturalmente e validada no Brasil, apresentando bom índice de confiabilidade: 0,75 (Soares & Vargas 2013, Vargas et al 2015. A MAVAS-BR é constituída por 23 itens e, desses, seis itens relacionamse ao modelo interacional/situacional; quatro, ao modelo externo; quatro, ao modelo biológico; e nove itens relacionados às atitudes de enfermeiros no manejo de pacientes violentos.…”
