External Validity of Conduct and Oppositional Defiant Disorders Determined by the NIMH Diagnostic Interview Schedule for Children

We administered the Diagnostic Interview Schedule for Children (DISC) two times to a group of youth (222 boys, 147 girls) entering residential care, once at their time of entry and once 1 year later. We then compared their DISC outcomes on Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD) against changes in independent direct observations of diagnostically relevant behavior obtained over the course of that year. Results from hierarchical linear modeling analyses showed significant discriminative relationships between results from the DISC and the independent observations. Specifically, observations of symptomatic behaviors (CD or ODD) decreased for youth who met diagnostic criteria at the first administration of the DISC but not at the second, increased for youth who did not meet criteria at the first administration but did at the second, and did not change for youth who met criteria at both administrations. These results extend the data on the validity of the DISC and support continued research efforts to determine its clinical utility.     

Physical and mental health trajectories of cancer patients and caregivers across the year post-diagnosis: a dyadic investigation

Objective: Evidence suggests interdependence between cancer patients’ and their caregivers’ physical and mental health. However, the extent to which caregivers’ health relates to their patients’ recovery, or patients’ health affects their caregivers’ outcomes, is largely unknown. This dyadic investigation reports the relations between cancer patients’ and their caregivers’ physical and mental health trajectories during the year following diagnosis.

Design: Ninety-two colorectal cancer patient–caregiver dyads completed questionnaires at 2, 6 and 12 months post-diagnosis.

Outcome measures: Self-reported physical and mental health using the Medical Outcomes Study Short Form Health Survey-12.

Results: Patients reported improved physical health over the year following their diagnosis, whereas caregivers reported declining physical health. Patients with lower mental health at diagnosis had stagnated physical health recovery. Caregivers’ physical health declined most noticeably among those reporting low mental health at diagnosis and whose patients reported low physical health at diagnosis.

Conclusion: Findings suggest targeting health interventions to cancer patients and caregivers reporting poor mental health at diagnosis may mitigate their long-term physical morbidity. Limited evidence of dyadic interdependence between patients’ and caregivers’ physical and mental health trajectories suggests future studies are warranted to identify psychosocial and medical characteristics moderating the relations between patients’ and caregivers’ health.     

Exact procedures for the analysis of multidimensional contingency tables

The log-linear model for contingency tables expresses the logarithm of a cell frequency as an additive function of main effects, interactions, etc., in a way formally identical with an analysis of variance model. Exact statistical tests are developed to test hypotheses that specific effects or sets of effects are zero, yielding procedures for exploring relationships among qualitative variables which are suitable for small samples. The tests are analogous to Fisher's exact test for a 2 × 2 contingency table. Given a hypothesis, the exact probability of the obtained table is determined, conditional on fixed marginals or other functions of the cell frequencies. The sum of the probabilities of the obtained table and of all less probable ones is the exact probability to be considered in testing the null hypothesis. Procedures for obtaining exact probabilities are explained in detail, with examples given.     

Coding factors in transcription

Two experiments looked at aspects of stimulus grouping by trainee typists and tested for the possibility of response grouping. Manipulating text preview indicated that typing speed declined if the next word was not wholly on display but, conversely, there was little gain if it was displayed much in advance of its being typed. Some of the effect of practice was specific to the words actually typed: words not presented during practice were typed slower than practised ones; others given reinforced practice were typed quicker than the rest. An analysis of response latencies provides evidence that response grouping sometimes occurred.     

Effects of preexisting moods on observers' reactions to helpful and nonhelpful models

Two experiments investigated the effects of preexisting mood on observers' reactions to helpful and nonhelpful models. The major predictions, derived from a social learning analysis of altruism and Isen's “cognitive loop” hypothesis, where that (1) subjects experiencing positive moods would be prosocially inclined if exposed to a helpful but not a nonhelpful model, and (2) subjects experiencing negative moods would accede to a request for assistance regardless of the type of model they had observed. Introductory psychology students underwent a positive, negative, or (in Experiment 1) a neutral mood induction. They then observed a model respond either positively or negatively to another person's request for assistance, and were subsequently provided an opportunity to assist the help-seeker. The results were highly consistent across the two experiments. The model's behavior had a stronger impact on subjects' help giving than did preexisting moods. However, internal analyses revealed that the intensity of moods that subjects were experiencing affected their reactions to modeling cues. The prosocial behavior of good mood subjects was positively correlated with the positivity of their moods if they had witnessed a helpful but not a nonhelpful model. By contrast, the helpfulness of subjects experiencing negative moods was positively correlated with the negativity of those moods, regardless of the type of model subjects had observed. The implications of these outcomes for the social learning analysis of altruism and the “cognitive loop” hypothesis are discussed.     

The effects of good moods on systematic processing: “Willing but not able,or able but not willing?”

Previous research has indicated that good moods may disrupt systematic processing of persuasive messages (e.g., Worth & Mackie, 1987). Three experiments were conducted to attempt a replication of this disruptive effect and determine whether this effect is attributable either to cognitive capacity deficits (i.e., ability) or to motivational concerns (e.g., mood maintenance, desire to think about something other than the experimental topic). Several similarities were noted across the experiments. First, no interactions between mood and argument strength emerged on measures of message-based persuasion. Similarly, the quantity of message-related thoughts generated by our subjects was not consistently influenced by the manipulation of mood. Most importantly, consistent findings regarding the relationship between polarity of message elaborations and message-based persuasion implied that good moods may have disrupted message processing when (a) the message was low in personal relevance, (b) source information preceded the message itself, or (c) subjects were led to believe that their moods were stabilized by a drug. These results call into question the robustness of the alleged disruptive effect of positive mood on systematic processing, and are incompatible with the view that such effects are attributable to cognitive capacity deficits.Portions of this research were presented at the Annual Meetings of the American Psychological Association, Boston, August 1990, and San Francisco, August 1991. The authors wish to thank Richard E. Petty and several anonymous reviewers for their helpful comments.     

Manufacturing multiple meanings of addiction: Time-limited realities

This article explores how clinicians, patients, and addiction as a youthful science manufacture meaning. Explanations of addictive behavior and addictive disease are viewed as constructs, ideologies, or ways of making meaning. This analysis considers the controversy—over whether addiction qualifies as a disease—to be primarily a matter of epistemology and social perception. Since there is no widespread agreement about what isease means in general, it is not possible to determine whether or not addiction is a disease in particular. The discussion also envisions how treatment for addicted clients might be reformulated as a transactional process utilizing the range of relevant theoretical models as time-limited reframes of addictive reality instead of dichotomizing addiction as either a disease or not.The authors extend thanks to Michelle Bowdler, Nancy Costikyan, Blase Gambino, Teri Loughead, Janet Mann, Peter Monius, Arthur Robbins, and Mitchell Young for their helpful assistance, suggestions, and comments on earlier drafts of this article.
