Time-varying and time-invariant dimensions of depression in children and adolescents: Implications for cross-informant agreement.

The longitudinal structure of depression in children and adolescents was examined by applying a Trait-State-Occasion structural equation model to 4 waves of self, teacher, peer, and parent reports in 2 age groups (9 to 13 and 13 to 16 years old). Analyses revealed that the depression latent variable consisted of 2 longitudinal factors: a time-invariant dimension that was completely stable over time and a time-varying dimension that was not perfectly stable over time. Different sources of information were differentially sensitive to these 2 dimensions.

Moderators of the relation between popularity and depressive symptoms in children: processing strength and friendship value.

Children with low (n = 25) and high (n = 38) peer-rated popularity completed an emotional Stroop task, using negative social words, a self-report measure of friendship value relative to other domains of competence, and the Child Depression Inventory (CDI). Six months later, they completed the CDI again. In regression analyses, after controlling for prior CDI scores, social status interacted significantly with both Stroop and value measures (separate regressions).

Quality of life of patients who have undergone the Nuss procedure for pectus excavatum: Preliminary findings.

Background/purpose: The current project is a preliminary qualitative exploration of changes in quality of life of patients who have undergone the Nuss Procedure. The current study explores quality of life after surgical repair from the perspectives of both the patients and the parent(s) of the younger participants.

Methods: This research constitutes the first segment in a mixed-method longitudinal design.

Individual differences in the emergence of depressive symptoms in children and adolescents: a longitudinal investigation of parent and child reports.

The authors address questions about the rate that depressive symptoms emerge, developmental and gender differences in this rate, and differences between parent and child estimates of this rate. In a 12-wave, cohort-sequential, longitudinal design, 1,570 children (Grades 4-11) and parents completed reports about children's depression. Cross-domain latent growth curve analysis revealed that (a) the rate of symptom growth varied with developmental level.
