    Author: Richey JA, Schmidt NB, Lonigan CJ, Phillips BM, Catanzaro SJ, Laurent J, Gerhardstein RR, Kotov R.
    Journal: J Child Psychol Psychiatry; 2009 Sep; 50(9):1147-55. PubMed ID: 19490307.
    Abstract:
    BACKGROUND: The current study examined the categorical versus continuous nature of child and adolescent depression among three samples of children and adolescents ranging from 5 to 19 years. METHODS: Depression was measured using the Children's Depression Inventory (CDI). Indicators derived from the CDI were based on factor analytic research on the CDI and included indices of: 1) social withdrawal, 2) anhedonia, 3) incompetence/maladjustment and 4) negative self-esteem. RESULTS: Taxometric procedures provided convergent support for the existence of a latent taxon across three independent samples. Internal and external consistency tests as well as Monte Carlo simulations supported the validity of the results. CONCLUSIONS: Multiple nonredundant procedures and samples were all consistently indicative of taxonicity in child depression.
