Social capital is considered a structural determinant of social development and wellbe- ing. Its cognitive component assesses the degree of confidence of the population in their systems for social organization, as well as community inter- actions to coordinate social responses to social problems. There are few available scales for mea- suring this construct. This work presents the ad- aptation to Spanish and psychometric validation of a scale for measuring social capital in a rural setting. The Wang Social Cognitive Scale was also adapted to Spanish. 1200 questionnaires were applied to adults in 12 villages of the municipali- ty of Tierra Alta, (Colombia) recruited by ran- dom sampling. Factor analysis of the scale was performed based on a polychoric correlation ma- trix. Exploratory factor analysis suggests the ex- istence of two principal factors distributed as fol- lows: 7 items for factor 1, trust (eigenvalue 3.23) and 2 items, for factor 2, distrust (eigenvalue 1.40). As observed by Wang, Q9 and Q10 could be ambiguous questions which do not contribute enough to either of the factors. The first factor validation to Spanish language of the Wang So- cial Capital Scale is presented in the social con- text of rural Colombia.
