The importance of irritability, as measured among the symptoms of oppositional defiant disorder (ODD), has dramatically come to the fore in recent years. New diagnostic categories rely on the distinct clinical utility of irritability, and models of psychopathology suggest it plays a key role in explaining developmental pathways within and between disorders into adulthood. However, only a few st...

While schizotypal features are common during adolescence, they can also signal increased risk for the onset of schizophreniform disorders. Most studies with adolescents find that hallucination and delusion-like symptoms (positive schizotypal features) best predict future psychopathology. Still, the developmental process of positive schizotypy remains elusive, specifically with regards to 1) its...

The numerous temperament and personality constructs in childhood impede the systematic integration of findings on how these individual differences relate to developmental psychopathology. This paper reviews the main temperament and personality theories and proposes a theoretical taxonomy representing the common structure of both temperament and personality traditions within one conceptual frame...

On September 11, 2001, a terrorist attack occurred in the U.S. (9/11). Research on 9/11 and psychiatric outcomes has focused on individual disorders rather than the broader internalizing (INT) and externalizing (EXT) domains of psychopathology, leaving unknown whether direct and indirect 9/11 exposure differentially impacted these domains rather than individual disorders. Further, whether such ...

Progress and innovation in DSM–V include the proposal of a new structural organization of disorders that stands to bring childhood and adult disorders together. Specifically, many common disorders would be grouped under broader dimensions of internalizing and externalizing problems. Although this distinction originated in childhood psychopathology research, current work has drawn heavily from s...

Although intended to assess vulnerability factors associated with psychopathology, the 5-Dimensional Personality Test (5DPT) shows at least a superficial similarity to instruments that adhere to the lexical tradition in personality psychology. To investigate to which extent this similarity goes, this article compares the 5DPT with 2 lexically based measures, the NEO-Five Factor Inventory and th...

OBJECTIVE It is frequently reported that patients with psychotic disorders have poor insight into their illness. Previous research has suggested that poor insight may have considerable power in predicting the long-term course of chronic mental disorders and an impact on patients' compliance with treatment plans. The authors, proposing that insight is best viewed as a multidimensional phenomenon...

OBJECTIVE The objective of this study was to examine the relationship between patient beliefs about medication use and their likelihood of discontinuing treatment prematurely. Associations of patient beliefs about medication with clinical psychopathology and their life satisfaction were also assessed. METHODS This post-hoc analysis used data from a randomized, open label, 1-year trial of anti...

Anxiety and depressive problems have often been related to higher hypothalamic-pituitary-adrenal (HPA)-axis activity (basal morning cortisol levels and cortisol awakening response [CAR]) and externalizing problems to lower HPA-axis activity. However, associations appear weaker and more inconsistent than initially assumed. Previous studies from the Tracking Adolescents Individual Lives Study (TR...

Prior empirical studies suggest that cognitive impairment is the strongest predictor of capacity to consent to research among persons with schizophrenia. Yet, despite the frequency and importance of cognitive deficits and impaired decisional capacity in schizophrenia, the scope of neuropsychological testing in most published reports in this area has been relatively narrow. In the present study ...
