Intelligence, classroom behavior, and academic achievement in children at high and low risk for psychopathology: a structural equation analysis.
The intelligence, academic achievement, and classroom behavior of 158 children were assessed in a sample that is being followed longitudinally. The sample included children at high risk for mental disorder by virtue of having a parent with a psychiatric diagnosis of schizophrenia or affective disorder, children at moderate risk, and children at low risk. A series of path analyses indicated that in this sample (1) classroom behavior was more likely an affect that a cause of academic achievement, and (2) the influence of parental psychopathology on classroom behavior was mediated by a child's intelligence and academic achievement. We were unable to substantiate an unmediated causal link between parental psychopathology and children's academic achievement or classroom behavior.

School behavior in adolescent children of parents with mental disorder.
This study examined teachers' evaluations of adolescent children of parents who had been hospitalized for mental disorder. Classroom behavior of these children as well as that of children of parents with physical illness was compared to that of adolescents whose parents had not been hospitalized for mental disorder. Both DSM-III and DSM-II categorizations were used. Two teacher-rated instruments were used. Adolescents with a parent with DSM-III diagnoses of schizophrenia and major affective disorder, as compared to children of nonill parents, were rated as less motivated, less harmonious, less stable, more dogmatic, and more verbally negative. Differences among children of parents with other diagnoses were generally less striking. Results using DSM-II diagnoses were similar to but weaker than those using DSM-III.

Perceived dimensions of attributions for loneliness.
This study examined the applicability of Weiner's model of causal attributions to lay explanations for the causes of loneliness. Weiner posits three dimensions (Internatily, Stability, and controllability) along which causes vary and links each dimension to distinct consequences for the actor. To test the salience of these dimensions in lay perceptions of causality, 180 college students made judgments about the causes of loneliness. As predicted, both exploratory and confirmatory multidimensional scaling analyses found that dimensions of Internality and Stability were perceived by respondents. Contrary to recent theorizing, Controllability was not independent of the other two dimensions; instead, controllable causes were both internal and unstable. Confirmation of Internality and Stability as dimensions underlying attributions for loneliness supported the extension of Weiner's model to the domain of affiliative behavior.

Longitudinal, prospective evaluations of intelligence in children at risk.
Data are presented from the intellectual assessment of 153 children at two test periods in the St. Louis Risk Research Project. At phase I (1967-72) the Wechsler tests of intelligence were administered to offspring in families with one schizophrenic parent, one parent with affective disorder, one parent with schizoaffective disorder, one physically ill parent, or to offspring with two normal parents (mean age, 8 years). At phase II (1975-78) the intelligence of offspring was tested again at a mean age of 16 years. Differences between children as a function of parental diagnoses were assessed using a repeated measures analysis of covariance. The analyses yielded significant time effects. A time-by-parental-diagnosis effect was found for Verbal IQ, with children of parents with schizophrenia, affective disorder, or physical illness all showing a greater decrease in their scores at the second testing than offspring in the other groups. Offspring of psychotic mothers had lower IQ scores than those of psychotic fathers. Children of schizophrenics and children of schizoaffectives had the lowest stability in IQ scores from the first to the second testing.

Relation between loneliness and depression: a structural equation analysis.
Research on loneliness has been hampered by its strong association with depression. The two states frequently co-occur, and measures of the two states are substantially correlated. Inability to manipulate experimentally loneliness or depression makes it difficult to untangle the causal influence of one on the other. The combination of longitudinal design and structural equation methodology is proposed as a solution to this general problem. Measures of loneliness and depression were administered to undergraduates at two points 5 weeks apart. Data from 333 subjects were correlated and analyzed under a succession of structural equation models. Results indicated that loneliness and depression were correlated but clearly different constructs; neither was a direct cause of the other, though both probably share some common origins; both were highly stable over to 5-week-period.
