Group Cognitive Behavioral Therapy and Attention Bias Modification for Childhood Anxiety Disorders: A Factorial Randomized Trial of Efficacy.

Background: The objective of this study is to assess group differences in symptom reduction between individuals receiving group cognitive behavioral therapy (G-CBT) and attention bias modification (ABM) compared to their respective control interventions, control therapy (CT), and attention control training (ACT), in a 2 × 2 factorial design.

Methods: A total of 310 treatment-naive children (7-11 years of age) were assessed for eligibility and 79 children with generalized, separation or social anxiety disorder were randomized and received G-CBT (n = 42) or CT (n = 37). Within each psychotherapy group, participants were again randomized to ABM (n = 38) or ACT (n = 41) in a 2 × 2 factorial design resulting in four groups: G-CBT + ABM (n = 21), G-CBT + ACT (n = 21), CT + ABM (n = 17), and CT + ACT (n = 20).

Psychometric properties of the Brazilian-Portuguese version of the Spence Children's Anxiety Scale (SCAS): self- and parent-report versions.

This study examined the psychometric properties of the Spence Children's Anxiety Scale (SCAS) self- and parent-report versions in a community (n=712) and a clinical (n=70) sample of Brazilian children and adolescents. Confirmatory factor analysis conducted in the community sample provided support to the original six correlated factors model of the SCAS. Moreover, the SCAS demonstrated good internal consistency, convergent and divergent validity, and a significant informant effect on the total score with higher anxiety levels in the self-report than in the parent-report version.

Brazilian Portuguese version of the Spence Children's Anxiety Scale (SCAS-Brasil).

Objective: To describe the cross-cultural adaptation of the Spence Children's Anxiety Scale (SCAS) for use in Brazil.

Methods: Cross-cultural adaptation followed a four-step process, based on specialized literature: 1) investigation of conceptual and item equivalence; 2) translation and back-translation; 3) pretest; and 4) investigation of operational equivalence. All these procedures were carried out for both the child and the parent versions of the SCAS.
