Diagnosis and Assessment of Depression and Suicidality Using the NIMH Diagnostic Interview Schedule for Children (DISC-2.3)

The Diagnostic Interview Schedule for Children (DISC-2.3) was studied in a sample of 265 adolescent inpatients to determine type and concurrent validity of depressive symptoms and depressive disorder diagnoses for different DISC-2.3 informants (parent, adolescent, both). The Children's Depression Rating Scale — Revised, Reynolds Adolescent Depression Scale (RADS), Suicide Ideation Questionnaire — Junior, Spectrum of Suicide Behavior Scale, and clinical consensus diagnoses were used to assess concurrent validity. Results indicated that (1) parents, compared to adolescents, reported a higher prevalence of all depressive symptoms with the exception of weight change; (2) DISC-2.3 depressive and suicidality symptoms were related positively to independent validating criteria for all informant conditions, suggesting good concurrent validity; (3) the DISC-2.3 both informant condition correctly identified the most depressive disorders; and (4) the parent, but not the adolescent, DISC-2.3 Informant condition contributed to the prediction of clinical consensus diagnoses of depression after taking into account RADS scores.     

The thinking heart: Developmental dynamics in Etty Hillesum'sdiaries

This essay has three purposes. First, it proposes a method for reading texts developmentally, noting the appropriate type of text for this enterprise, the process for estimating the subject's developmental perspective, and necessary cautions when undertaking a developmental interpretation. Second, it highlights developmental dynamics which can be approximated in other contexts. Finally, it lifts up the writings of an extraordinary young Dutch woman, a victim of Auschwitz, offering her life as a model of virtues which our society would do well to imitate more than fifty years after the Holocaust.Where she also directs the Program in Christian Spirituality.     

On “knowing your partner”: Dangerous illusions in the age of AIDS?

We identified two characteristics of the impression formation process that may cause people to underestimate the riskiness of potential sexual partners. In Study 1, participants were quite confident that they could determine whether someone was lying to them about risk-related behavior when, in reality, they could not. Particularly troubling was a “truth bias” that resulted in relatively high rates of truth detection, but poor lie detection. In Study 2, increased familiarity with a target person (who actually was HIV+) caused participants to lower their estimates of the target's riskiness, despite the fact that we explicitly warned them that the target might be HIV+. We suggest that such processes may foster the illusion of knowing one's partner when one does not.     

Deceived versus nondeceived participants' perceptions of scientific and applied psychology

Research examining the possible effects of deceptive research participation on participants' perceptions of psychology has yielded equivocal results. The present study's goal was to clarify the possible effects of participation in mildly deceptive research on participants' impressions of scientific and applied psychology. Participants (N = 112) were randomly assigned to one of six experimental conditions: active groups receiving negative, positive, or no feedback, or passive groups receiving negative, positive, or no feedback. Following participation, participants completed measures of impressions of psychotherapy and psychotherapists, researchers, and instructors. The manipulation did not affect attitudes toward psychology on any of the dependent measures, although gender effects resulted on one measure. Participants in general reported very positive attitudes toward the science and practice of psychology. Recommendations are offered for future research on the effects of more extensive deceptions.     

Parents, infants, and day-care teachers: Interrelations and implications for better child care

Many young children are reared today in both family and child-care settings. The relation that exists between these two settings has important implications for child care. Bronfenbrenner's (1979) ecological model is used as a way to view the interrelations among children, families, and child-care programs. Data from a study of infants in day care provide information on the time infants spend in family and day-care contexts, how parents and caregivers view children's behavior in these two settings, and rates of otitis media (ear infections) and other illnesses for these children. Results show that infants spend about twice as many hours per day awake with parents as in day care. Regarding child behaviors, parents and caregivers seem to have similar behaviors they like and dislike, but they each see particular children quite differently with respect to these behaviors. Finally, infants in this sample were diagnosed with illnesses 60% to 70% of the time. Findings are discussed in terms of the ecological model with particular attention given to relations between parents and caregivers.     

Orienting the finger opposition space during prehension movements

Two experiments are reported that examined the act of prehension when subjects were asked to grasp with their thumb and index finger pads an elongated object resting horizontally on a surface and placed at different orientations with respect to the subject. In Experiment 1, the pad opposition preferences were determined for the six angles of orientation examined. For angles of 90 degrees (object parallel to frontal plane) or less, no rotation of the wrist (pronation) was used; for angles 110 degrees or greater, pronation was systematically employed to reorient the finger opposition space. Only one angle, 100 degrees , produced any evidence of ambiguity in how to grasp the object: Approximately 60% of these grasps involved pronation and 40% did not. Using the foregoing grasp preference data, in Experiment 2 we examined the kinematics of the wrist and elbow trajectories during prehension movements directed at an object in different orientations. Movement time, time to peak acceleration, velocity, and deceleration were measured. No kinematic differences were observed when the object orientation either required (110 degrees ) or did not require (80 degrees ) a pronation. By contrast, if the orientation was changed at the onset of the movement, such that an unpredicted pronation had to be introduced to achieve the grasp, kinematics were affected: Movement time was increased, and the time devoted to deceleration was lengthened. These data are interpreted as evidence that when natural prehension occurs, pronation can be included in the motor plan without affecting the movement kinematics. When constraints are imposed on the movement execution as a consequence of a perturbation, however, the introduction of a pronation component requires kinematic rearrangement.     

Robust conditioned flavor preferences with a sensory preconditioning procedure

During sensory preconditioning, rats were given two distinct flavors (saccharin and coffee) in sequence with 0, 9, or 27 sec between the two flavors. A control group received the flavors unpaired. In subsequent training, the second flavor preceded sucrose by 5 min. Later, the subjects that had had 0- or 9-sec delays between the two flavors showed a significant preference for the flavor not directly reinforced, whereas those that had had a 27-sec delay showed only a marginally significant preference. Although taste aversions have been produced using these methods, this is the first demonstration of conditioned preferences for flavors not directly associated with the reinforcers. These results offer an alternative way to study flavor-flavor learning.     

Cooperative learning revisited

The endeavor to teach academic skills known as cooperative learningis of interest to behavioral educators due to its record of effectiveness, its use of behavioral procedures, and its relatively widespread adoption by regular educators. All forms of cooperative learning emphasize operations that encourage students to work together to achieve commonly held goals rather than competing with or ignoring the efforts of others. Despite the apparent soundness of the approach, the present commentary raises several issues. First, it states that some cooperative learning proponents fail to describe the behavioral processes underlying the approach. Second, it is pointed out that it is unclear whether cooperative learning is an independent or dependent variable. Given that cooperative learning applies group contingencies to academic behavior, the question is raised as to whether group contingencies do, in fact, produce desirable social interactions, and whether group contingencies are appropriate for academic behaviors. A concern is also raised as to whether the spontaneous peer tutoring generated by cooperative learning compares favorably with planned peer tutoring. Finally, it is claimed that the minor variations from academic group contingencies that cooperative learning proponents have introduced do not require identifying a new process.     

Reliability of self-reported service use: Test-retest consistency of children's responses to the Child and Adolescent Services Assessment (CASA)

This paper reports on the reliability of children's responses on the Child and Adolescent Services Assessment (CASA) — a self-report instrument for use with 8– to 18-year-olds that gathers information about services used to address mental health problems. Findings were based on interviews completed by 77 children at a one week test-retest interval. Results showed that reports of lifetime service use were as reliable as were reports of service use in the preceding three months. Children reported restrictive and intrusive services more reliably than services that were provided in their natural environment. Reliability appeared to be associated more strongly with characteristics of the type of service than with characteristics of the child. Children also could report reliably on some details about their encounters with service providers (e.g., length of stay, number of visits, and onset of service use).
