Methodology for identifying specific psychological deficits: introduction to the special section

A long-standing problem in psychopathology research is establishing that patterns of differences between groups reflects differences of underlying constructs and not artifacts of research design, measurement, or analysis. This introduction provides a context for 4 articles that consider several controversial issues regarding this problem and presents a précis. Although these articles focus on schizophrenia, it is noted how the issues are of more general relevance to psychopathology researchers.     

The acquisition of taste aversions in humans

A written questionnaire or an interview was given to 517 undergraduates concerning their acquisition of illness-induced (taste) aversions to foods and drinks. The subjects reported 415 aversions, with 65% of the subjects reporting at least one aversion. The aversions were more likely to be reported as having been formed through forward rather than simultaneous or backward conditioning, and long-delay learning was frequent. The aversions usually formed to the taste of the foods, rather than the appearance or other aspects of the foods. Extinction appeared more effective in decreasing the aversions than did forgetting. The illness responsible for the aversion's forming was usually attributed to the subsequently aversive food, but for 21% of the reported aversions subjects were sure that something else had caused their illness. Aversions were more likely to have formed to relatively less familiar and less preferred foods. Aversions were also more likely to form between the ages of 13 and 20. Generalization of the aversions to similar foods occurred in 29% of the cases. Approximately one fourth of the aversions were to alcoholic beverages. Finally, instances of aversions forming without food or drink consumption and instances of observational learning were reported. The data were quite similar to laboratory taste aversion data collected using other species and can help in optimizing taste aversion treatments of eating and drinking disorders. Taste aversions among humans are frequent and strong.     

Identifying the multi-risk family prenatally: Antecedent psychosocial factors and infant developmental trends

Little is known about the relationship between mother and infant within multiproblem, so-called “hard to reach” families. In an effort to understand factors contributing to problems in caring for the young children of these parents, a group of 47 families was recruited for study by the Clinical Infant Development Program of the National Institute of Mental Health. Serious social pathology was found within 75 percent of families. The lives of mothers in these families was marked by long term disruptions: 64 percent were from families characterized by recurring poverty and psychiatric illness, and 69 percent reported disruptions in parental care prior to age twelve, while more than two-thirds reported a history of being physically and/or sexually abused as children. More than 75 percent of this group of women presently showed psychiatric distress. Many of these women have difficulty in providing adequately for their young children and require innovative intervention programs in order to facilitate parenting.

The Last-Weiss Rorschach Ego-Strength Scale as a prognostic measure for psychiatric outpatients

This study tested the hypothesis that the Last and Weiss (1976) Rorschach Ego-Strength Scale (sigma E) would predict outcome among a representative sample of never-hospitalized psychiatric outpatients. 78 patients were assessed with structured symptom, psychiatric history, and social data interviews at the time of initial clinic contact and at 2-yr. follow-up. Outcome measures included the Menninger Health-Sickness Scale, a multidimensional variable involving social and work functioning and recent symptom level, symptom measures, and an index of diagnostic severity. sigma E, controlled for number of responses, correlated significantly with Health-Sickness, neurotic symptoms, diagnostic severity, and psychotic symptomatology. Among the components of sigma E, M+, and FC+ had significant relationships or contributed to significant relations with outcome variables. Considered with an earlier study of inpatients, in which S+ sigma E component correlated inversely with outcome, this study suggested that sigma E components have differing prognostic significance, depending on adaptational level of the patient.     

The association between social withdrawal and internalizing problems of children

Children identified as low-frequency interactors or socially withdrawn were compared to outgoing children to evaluate whether socially withdrawn children display concurrent internalizing problems. From a sample of 640 children in grades 2-5, 48 children were identified by teachers as low-frequency interactors and 72 children were selected as outgoing or sociable. When these two groups were compared on a battery of teacher, peer, and self-report measures that assessed internalizing difficulties, the low-frequency interactors were found to display concurrent problems in adjustment. Children who rarely interacted with peers were less well liked by their peers, displayed poorer self-concepts, and were more depressed and anxious than sociable children. In contrast to these findings regarding internalizing problems, the two groups did not differ on measures of externalizing problems. The results lend support to the concurrent validity of the low-interaction method of identifying socially withdrawn children.
