Psychometric propierties of the Selective Mutism Questionnaire in Spanish children.

Unlabelled: Research on selective mutism (SM) has been limited by the absence of standardised, psychometrically sound and cross-culturally valid assessment measures. Our aim is to present the results of a study of the factor structure and the reliability and concurrent validity of the scores of the Selective Mutism Questionnaire (SMQ), translated and adapted into Spanish. The SMQ contains 17 items about children's difficulty in speaking adequately in the family, school and social environment (out-of-school and out-of-family), each of which is answered according to a Likert scale with four response alternatives on speech frequency.

Role of social skills training in adolescents with social anxiety disorder.

Social skills training (SST) is frequently included in the treatment of social anxiety disorder (SAD) in both children and adolescents, although there is no empirical evidence to support it. Consequently, our objective is to study the role and effects of SST in the treatment of a sample of adolescents with SAD. A total of 108 adolescents diagnosed with generalized social phobia were randomly assigned to two treatment conditions (with and without SST) and a control group waiting list (WLCG).
