Social skills training in children with PDD-NOS: an exploratory study

Objective. A deficit in social interaction is characteristic for children with Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS). The aim of this exploratory study is to assess the effect of Social Skills Training (SST) in children with DSM-IV based PDD-NOS. Methods. Ten consecutively referred children (n = 3 girls and n = 7 boys, mean age = 8.5, mean Full Scale Intelligence Quotient [FSIQ] = 104) participated in the standardized SST in a university outpatient department of child psychiatry. The valid and reliable Children's Social Behaviour Questionnaire (CSBQ) and Self-Perception Profile for Children (SPPC) were filled out pre- and post treatment by parents and children respectively. Results. Parent's CSBQ total and subscale "Social understanding" scores were significantly lower after the SST. Children's scores on the subscale "Scholastic Competence" of the SPPC were significantly higher after SST, whereas their scores on the SPPC subscale "Physical Appearance" were significantly lower after SST as compared to before. Conclusions. This study provides a first indication of positive effects of SST in children with PDD-NOS.
