FUNVECA and the APYTEC research group of the University of Granada have been working in the area of social skills for many years. Our team has numerous publications on this subject, among which the book Handbook of assessment and training of social skills, written by Professor Vicente E. Caballo, is one of the best sources of information on the area. In addition, our team has recently developed a new questionnaire to assess social skills, the “Social Skills Questionnaire” (SOSAQ), validated in Spain and numerous Latin American countries.
