The scores for depression and anxiety disorder were used to construct an index for internalizing disorder.
A recent meta-analytic review of cross-sectional studies examining correlations between peer victimization and indices of internalizing problems indicates that victims of bullying are highly distressed.
With the standardized scores, two composite indices for internalizing and externalizing symptoms were computed.
The total difficulties score (range: 0 40) is determined by aggregating the indices for internalizing and externalizing behavior problems.
Scores on the separate indexes form internalizing and externalizing scores that were used to calculate a total score.
To examine reciprocal relationships between body mass index (BMI) and internalizing and externalizing problems from infancy through middle childhood, with a focus on sex and history of overweight.
Furthermore, 4 (7%) children with CIs and 10 (13%) children with hearing aids scored 1 SD above the mean on both internalizing and externalizing indices.
Composite scores are derived by the publisher's computerized scoring program for externalizing, internalizing, and Behavior Symptom Index (BSI) scales, each with clinical subscales.
Additionally, we used separate linear mixed models for Internalizing Problems, Behavior Symptoms Index, Adaptive Skills, and BASC-2 subscales for attention problems, aggression, anxiety, and withdrawal at 2, 3, 4, and 5 years.
In the study of Kaufman et al. [ 11], CBCL/4-18 internandzing and externalizing scales were used as indices to determine validity of the original K-SADS-PL in a sample of 66 children aged 7-17 years (55 outpatients and 11 controls).
