Classes of Oppositional Defiant Disorder Behavior in Clinic-referred Children and Adolescents: Concurrent Features and Outcomes: Classification Des Comportements Dans le Trouble Oppositionnel Avec Provocation Chez Des Enfants et des Adolescents Aiguillés à Une Clinique: Caractéristiques Co-occurrentes et Résultats.

OBJECTIVE: Oppositional defiant disorder (ODD) consists of irritable and oppositional behaviors, both of which are associated with different problems. However, it is unclear whether irritability and oppositionality enable classification of clinic-referred children and adolescents into mutually exclusive groups (e.g., high in oppositionality, low in irritability), and whether this classification is clinically meaningful. METHOD: As part of a clinical protocol, ODD behaviors were assessed at referral through a comprehensive diagnostic interview and questionnaire. Parent- and teacher-reported ODD of 2,185 clinic-referred 5- to 18-year-olds (36.9% females) were used in latent class analysis. Resulting ODD classes were compared, concurrently at referral, and, longitudinally at the end of the diagnostic and treatment process, on various clinically relevant measures that were completed by various informants, including mental health problems, global functioning, and Diagnostic and Statistical Manual of Mental Disorders (DSM) classifications. RESULTS: Three classes emerged with high, moderate, and low levels of both irritability and oppositionality. At referral, the high class experienced the highest levels of mental health problems and DSM classifications. Importantly, all ODD classes defined at intake were predictive of diagnostic and treatment outcomes months later. Notably, the high class had higher rates of clinician-based classifications of ODD and conduct disorder, and the lowest levels of pre- and posttreatment global functioning. Additionally, the low class exhibited higher rates of generalized anxiety disorder and fear disorders. CONCLUSIONS: Irritability and oppositionality co-occur in clinic-referred youths to such an extent that classification based on these behaviors does not add to clinical inference. Instead, findings suggest that the overall ODD severity at referral should be used as a guidance for treatment.

A developmental analysis of self-reported fears in late childhood through mid-adolescence: social-evaluative fears on the rise?

BACKGROUND: The frequently reported decline in the overall frequency and intensity of fears during late childhood and adolescence may mask different developmental patterns for two broad subclasses of fears: fears concerning physical danger and fears concerning social evaluation. It was investigated if physical fears decrease between late childhood and mid-adolescence, while social-evaluative fears increase during this period. It was also studied if changes in both sets of fears are more strongly related to socio-cognitive maturity than to age, which itself is only a proxy measure of maturity. METHODS: A non-clinical sample of 882 children and adolescents (ages 8-18) was recruited for study. Fears were assessed using the Ollendick Fear Survey Schedule for Children-Revised (FSSC-R). A Principal Components Analysis (PCA) was conducted to study the factor structure of the Failure and Criticism subscale of the FSSC-R. Level of development was assessed using the Sentence Completion Test for Youth (SCT-Y), a measure of socio-cognitive maturity that is based on Loevinger's model, and measure, of ego development. RESULTS: The PCA of the Failure and Criticism subscale revealed three factors: Social Evaluation, Achievement Evaluation, and Punishment. As predicted, the significant decrease of overall fearfulness obscured two contradictory developmental patterns: (a) fears of physical danger and punishment decreased with age, whereas (b) fears of social and achievement evaluation increased with age. Hierarchical regression analyses showed that the age effect for social-evaluative fears was explained entirely on the basis of developmental differences in socio-cognitive maturity (controlling for verbal ability). In contrast, age was a better predictor of the decrease of physical and punishment fears (although socio-cognitive maturity still added to the predictive value of age). CONCLUSION: The expression of social evaluation fears during adolescence appears not atypical and might be a corollary of socio-cognitive maturation. At the same time, the natural presence of those fears during adolescence appears to constitute a vulnerability for developing a social anxiety disorder.
