BONANATO, Karina et al. Trans-cultural adaptation and psychometric properties of the 'Sense of Coherence Scale' in mothers of preschool children. Interam. j. psychol. [online]. 2009, vol.43, n.1, pp. 144-153. ISSN 0034-9690.

The aim of this paper is to present the trans-cultural adaptation and reliability of the Sense of Coherence scale (SOC-13 from Antonovsky) into Portuguese language using a sample of mothers of preschool children. The originally validated scale demonstrated a low return percentage and high number of extreme answers when applied to mothers of preschool children selected by convenience sampling in Brazil. Adaptations were made through cognitive interviews and involved rewording items, the usage of five rather than seven alternatives and the insertion of middle anchoring phrases. Three independent samples took part in the study for the psychometric tests. These samples consisted of one group of 36 and another of 38 mothers selected by convenience, as well as an additional group of 546 mothers randomly selected from the city of Belo Horizonte, Brazil. Instrument reliability was accessed by internal consistency, test-retest and item-to-total-score correlations with each of the three samples, respectively. Findings indicate that the adapted scale is comprehensible and obtained a greater response rate than the originally validated scale. Internal consistency increased from 0.67 for the original scale to 0.71 for the adapted scale. This value was extended to 0.80 in the test with the randomly selected sample. Medium weighted Kappa coefficients were 49.5%. The Spearman test demonstrated that the questions were correlated with total SOC scores. Results indicate that the adapted scale is valid and consistent for mothers of preschool children from different social classes.
