Abstract

MARTINEZ, Edson Zangiacomi; ALMEIDA, Rodrigo Guimarães dos Santos; GARCIA, Fabiana Rodrigues  and  CARVALHO, Antonio Carlos Duarte de. Notes on the Portuguese-language version of the Spiritual Well-Being Scale. J. bras. psiquiatr. [online]. 2013, vol.62, n.1, pp.76-80. ISSN 0047-2085.  http://dx.doi.org/10.1590/S0047-20852013000100010.

OBJECTIVE: This study aims to test the factor structure of the Portuguese-language version of the Spiritual Well-being Scale (SWB) in a sample of postgraduate students of courses in the health area, assessing its psychometric qualities. Among the different instruments used to measure the spirituality, the SWB was recently adapted into Portuguese language. The 20 items of this instrument are originally divided into two dimensions: Religious Well-Being (RWB) and Existential Well-Being (EWB) subscales. METHODS: The internal consistency of the subscales was assessed by the Cronbach's alpha coefficient. A factor analysis with oblique rotation was used to assess the latent factor structure. Four hundred and forty-one individuals answered the SWB scale. RESULTS: The instrument has satisfactory internal consistency, but the factor analysis suggests that the items of the EWB subscale are distributed in two distinct factors, which draws attention to the complexity of the factor structure of the instrument. CONCLUSION: The factorial structure of the instrument is unclear, and the presence of a ceiling effect for religious groups may hinder the studies about the associations between spirituality and health-related characteristics. The use of the SWB scale requires caution and a subsequent revision of the scale is needed.
