We examined the persistence of psychiatric disorders at approximately 18 and 30 months after a hurricane among a random sample of the child and adolescent population (4-17 years) of Puerto Rico. Data were obtained from caretaker-child dyads (N = 1,886) through in person interviews with primary caretakers (all children) and youth (11-17 years) using the Diagnostic Interview Schedule for Children...

This study examined the association between age of onset and persistence of externalizing behavior and young adults' cannabis use disorders (CUDs). Data were from a 21 year follow-up of a birth cohort study in Brisbane, Australia. The present cohort consisted of 2225 young adults who had data available about CUDs at 21 years and externalizing behavior at 5 and 14 years. Young adults' CUDs were ...

Recent research has suggested that individuals may respond to differing treatment approaches with varying degrees of success depending upon their personality characteristics. The current paper attempts to examine how a tendency to engage in externalizing behaviors, as measured by the Child Behavior Checklist, may impact on treatment success for anxiety in a sample of 71 children. Results lent p...

BACKGROUND While dimensional models of psychopathology have delineated two broad factors underlying common mental disorders--internalizing and externalizing--it is unclear where bipolar disorder and nonaffective psychoses fit in relation to this structure and to each other. Given their low prevalence rates in the general population, these disorders generally tend to be excluded from such models...

Numerous studies have examined the structure of the childhood externalizing disorder symptoms of Attention Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD), and Conduct Disorder (CD), both separately as well as simultaneously. The present study expanded on previous findings by implementing a multi-level hierarchical approach to investigating the component structure of ...

BACKGROUND Prior studies of common disorders in community-dwelling adults identified internalizing and externalizing spectra of mental illness. We investigated the placement of schizophrenia and schizotypal personality disorder in this framework and tested the validity of the resulting organization in a clinical population. METHODS The data came from the Suffolk County Mental Health Project c...

BACKGROUND Individuals at high risk to develop alcoholism often manifest neurocognitive deficits as well as increased impulsivity. The goal of the present study is to elucidate reward processing deficits, externalizing disorders, and impulsivity as elicited by electrophysiological, clinical and behavioral measures in subjects at high risk for alcoholism from families densely affected by alcohol...

BACKGROUND The first aim was to use confirmatory factor analysis (CFA) to test a hypothesis that two factors (internalizing and externalizing) account for lifetime co-morbid DSM-IV diagnoses among adults with bipolar I (BPI) disorder. The second aim was to use confirmatory latent class analysis (CLCA) to test the hypothesis that four clinical subtypes are detectible: pure BPI; BPI plus internal...
