Objective: The identification of reliable predictors of course in major depressive disorder (MDD) has been difficult. Evidence suggests that the co-occurrence of personality pathology is associated with longer time to MDD remission. Interpersonal pathoplasticity, the mutually influencing nonetiological relationship between psychopathology and…

Examined the relationships of reading and math achievement with intelligence and adaptive behavior in Anglo, Black, and Mexican American children (N=345). The variance accounted for by the full model (race, sex, age, and socioeconomic status) was significant for reading and math. Variance associated with race and socioeconomic status was…

Used the demographic variables of age, race, sex, education, occupation, region of residence, urban versus rural residence, and handedness in the prediction of premorbid IQs for the 1981 revised Wechsler Adult Intelligence Scale (N=1,880). Results indicated that the regression equations aid in accurate estimation of premorbid IQ. (LLL)

Numerous studies conducted with offender or forensic psychiatric samples have revealed that individuals with psychopathic traits are at risk for violence and other externalizing psychopathology. These traits appear to be continuously distributed in these samples, leading investigators to speculate on the presence of such traits in the general…

Verbal skills were assessed at approximately ages 2, 3, 5, and 9 years for 206 children with a clinical diagnosis of autism (n = 98), pervasive developmental disorders-not otherwise specified (PDD-NOS; n = 58), or nonspectrum developmental disabilities (n = 50). Growth curve analyses were used to analyze verbal skills trajectories over time.…

The Wechsler Adult Intelligence Scale was administered to 30 male criminally insane patients and 15 violent convicts. The latter had similar subtest score configurations and the mean similarities ratio score for the violent group was significantly lower than that of the nonviolent group. (Author/SE)

Two measures of "breadth" and three measures of "depth" were derived, based on special administration and scoring of the Wechsler Similarities subscale. Factor analyses indicated that breadth and depth can be distinguished statistically, and multiple regression analyses revealed that the derived measures contributed to improved…

Concludes that age-related declines in intelligence and spontaneous flexibility during adulthood cannot be explained by increased anxiety. Age is a significant predictor either alone or with anxiety level taken into account, but anxiety level and the age/anxiety interaction do not add significantly to the prediction. (Author)

The accuracy of the prediction of criminal violence may be improved by combining psychopathy with other variables that have been found to predict violence. Research has suggested that assessing intelligence (i.e., IQ) as well as psychopathy improves the accuracy of violence prediction. In the present study, the authors tested this hypothesis by…

Although Verbal IQ of the Wechsler Intelligence Scale for Children predicts statistically distinct Wide Range Achievement Test Reading scores dependent on the sex of the child, the differences are of little practical importance. (Author)

Although a 2-factor model has advanced research on the psychopathy construct, a 3-factor model was recently developed that emphasized pathological personality and eliminated antisocial behavior. However, dropping antisocial behavior from the psychopathy construct may not be advantageous. Using a large sample of psychiatric patients from the…
