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...

OBJECTIVE The anxiety and depressive disorders exhibit high levels of lifetime comorbidity with one another. The authors examined how genetic and environmental factors shared by the personality trait neuroticism and seven internalizing disorders may help explain this comorbidity. METHOD Lifetime major depression, generalized anxiety disorder, panic disorder, agoraphobia, social phobia, animal...

OBJECTIVE To compare anxiety symptoms and disorders in children and adolescents with recurrent abdominal pain (RAP), anxiety disorders, and healthy control children. METHODS Twenty-one children with RAP (nine males, mean age = 11.05) were compared to 21 children with anxiety disorders (11 males, mean age = 12.29), and 21 children without pain or anxiety (nine males, mean age = 11.57) using di...

INTRODUCTION Internalizing disorders of childhood are a common and disabling problem, with sufferers at increased risk of subsequent psychiatric morbidity. Several studies have found associations between parenting styles and children's internalizing, although few have considered the role of parental discipline. Parental discipline style may exert an effect on children's internalizing symptoms. ...

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...

OBJECTIVE The aim of this study was to assess predictors of placebo response in all available short-term, placebo-controlled trials of psychotropic drugs for children and adolescents with internalizing disorders, major depressive disorder (MDD), obsessive compulsive disorder (OCD,) and anxiety disorders (ANX) exclusive of OCD and posttraumatic stress disorder (PTSD). METHOD We reviewed the li...

This investigation examined how two commonly employed measures of functional impairment (the Child and Adolescent Functional Assessment Scale [CAFAS] and the Global Assessment of Functioning [GAF] scale) perform with respect to assessing levels of functional impairment and, hence, identifying rates of serious emotional disturbance (SED) across youth diagnosed with internalizing or externalizing...

Recent progress toward the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders includes a proposed quantitative hierarchical structure of internalizing pathology with substantial, supportive evidence (D. Watson, 2005). Questions about such a taxonomic shift remain, however, particularly regarding how best to account for and use existing diagnostic categories and models of...
