Children of Few Words: Relations Among Selective Mutism, Behavioral Inhibition, and (Social) Anxiety Symptoms in 3- to 6-Year-Olds

Children with selective mutism (SM) fail to speak in specific public situations (e.g., school), despite speaking normally in other situations (e.g., at home). The current study explored the phenomenon of SM in a sample of 57 non-clinical children aged 3-6 years. Children performed two speech tasks to assess their absolute amount of spoken words, while their parents completed questionnaires for measuring children's levels of SM, social anxiety and non-social anxiety symptoms as well as the temperament characteristic of behavioral inhibition. The results indicated that high levels of parent-reported SM were primarily associated with high levels of social anxiety symptoms. The number of spoken words was negatively related to behavioral inhibition: children with a more inhibited temperament used fewer words during the speech tasks. Future research is necessary to test whether the temperament characteristic of behavioral inhibition prompts children to speak less in novel social situations, and whether it is mainly social anxiety that turns this taciturnity into the psychopathology of SM

The development and psychometric evaluation of the group schema therapy rating scale: Revised

BACKGROUND: Recent research has supported the efficacy of schema therapy as a treatment for personality disorders. A group format has been developed (group schema therapy; GST), which has been suggested to improve both the clinical and cost-effectiveness of the treatment. AIMS: Efficacy studies of GST need to assess treatment fidelity. The aims of the present study were to improve, describe and evaluate a fidelity measure for GST, the Group Schema Therapy Rating Scale - Revised (GSTRS-R). METHOD: Following a pilot study on an initial version of the scale (GSTRS), items were revised and guidelines were modified in order to improve the reliability of the scale. Students highly experienced with the scale rated recorded GST therapy sessions using the GSTRS-R in addition to a group cohesion measure, the Harvard Community Health Plan Group Cohesiveness Scale - II (GCS-II). The scores were used to assess internal consistency and inter-rater reliability. Discriminant validity was assessed by comparing the scores on the GSTRS-R with the GCS-II. RESULTS: The GSTRS-R displayed substantial internal consistency and inter-rater reliability, and adequate discriminate validity, evidenced by a weak positive correlation with the GCS-II. CONCLUSIONS: Overall, the GSTRS-R is a reliable tool that may be useful for evaluating therapist fidelity to GST model, and assisting GST training and supervision. Initial validity was supported by a weak association with GCS-II, indicating that although associated with cohesiveness, the instrument also assesses factors specific to GST. Limitations are discussed
