The present study was conducted to construct and validate a questionnaire of social and cultural capital in the foreign language context of Iran. To this end, a questionnaire was designed by picking up the most frequently-used indicators of social and cultural capital. The Factorability of the intercorrelation matrix was measured by two tests: Kaiser-Meyer-Olkin test of Sampling Adequacy (KMO) and Bartlett’s Test of Sphericity. The results obtained from the two tests revealed that the factor model was appropriate. To validate the questionnaire, Exploratory Factor Analysis (EFA) was performed. The application of the Principle Component Analysis to the participants’ responses resulted in 14 extracted factors accounting for 69% of the variance. The results obtained from the Scree Test indicated that a five-factor solution might provide a more parsimonious grouping of the items in the questionnaire. The rotated component matrix indicated the variables loaded on each factor so that the researchers came up with the new factors, i.e., social competence, social solidarity, literacy, cultural competence, and extraversion. Finally, statistical results were discussed and suggestions were made for future research.
