Dream content of schizophrenic, nonschizophrenic mentally ill, and community control adolescents

This study compared the manifest dream content of 20 schizophrenic adolescent inpatients whose medications were stable for at least four weeks, 21 adolescent inpatients with other mental disorders (nonschizophrenic group) matched for age and gender, and 31 matched community controls. All participants were administered the standardized Formal Dream Content Rating Scale (FDCRS), which evaluates dream-related anxiety, cognitive disturbance, implausibility, involvement, primitivity, and recall, as well as two additional scales measuring emotional expression and duration of dream report. The Positive and Negative Symptoms Scale (PANSS) was administered to the two inpatient groups. The community controls demonstrated more involvement and emotional expression than the schizophrenic patients; furthermore, they demonstrated more implausibility and had a greater duration of dream report compared with the nonschizophrenic group. In the schizophrenic patients only, elevated scores on the negative subscale of the PANSS were significantly correlated with lower scores on involvement, emotional expression, and dream recall. No relationship was found between the positive subscale of the PANSS and any of the FDCRS subscales. These results suggest that psychopathology per se, rather than the specific psychiatric disturbance, may be associated with impoverishment of dream content, and that negative, rather than positive, schizophrenic symptomatology may be influential in the dream content of schizophrenic youngsters.

A discrete time model for detection of randomly presented stimuli

Considered in this paper is a discrete-time Markov decision process with unobservable states, which occurs in equipment checking, medical diagnosis, signal detection, and reaction time studies. The process is characterized by (i) a state S₀ that at some unknown time t, which is determined probabilistically, turns into an absorbing state S₁; (ii) observations that provide fallible information about the true state and which are taken sequentially to determine whether or not the change from S₀ to S₁ has occurred; and (iii) losses for a false alarm and for delays in detecting the change. A response model is proposed, prescribing a terminal decision as soon as the posterior probability that S₁ obtains reaches or exceeds a fixed probability boundary. Predictions are derived concerning the probability of false alarm and several conditional distributions of the number of observations taken.     

A theory of argumentative understanding: Relationships among position preference,judgments of goodness,memory and reasoning

Data are presented that focus on the nature and development of argumentative reasoning. In particular our study describes how support for or against an issue affects memory for critical parts of an argumentative interaction, judgments of argument goodness, and the content of the reasons given in support of one view versus another. Two other factors were examined: developmental differences in argumentation skill and the conditional nature of supporting one side of an argument across varying contexts. Our results show that even seven year old children can recognize, identify, and use the basic components of an argument to provide evidence for and make judgements about their favored position. Moreover, if position support is held constant across all age groups of students, seven year old children were found to give reasons and explanations that were highly similar in content and principle to college students. The same similarities held across age with respect to biases in memory and judgements of argument goodness. The primary difference between children's and college students' argument behavior lay in the side of an argument the students chose to support. Seven year old children and some eleven yearold children supported positions that impute more value to friendship and social consequences than to the maintenance and advancement of individual rights, as specified in a contract agreement. The similarities and differences across development are discussed with respect to a theory of argumentation that speaks to the importance of understanding the nature of goal conflict and a theory of intentionality in predicting how arguments will be represented and resolved.     

Who enrolls in prevention trials? Discordance in perception of risk by professionals and participants

Internal and external validity problems permeate all intervention studies but are accentuated in primary preventive intervention research, particularly when studies target or recruit individuals based on their risk for psychopathology. Since many people who are at risk do not yet experience distress, they may not perceive the need for intervention. Recruitment tactics based on explaining extent of risk are unlikely to be persuasive and may have negative consequences. If respondents are not motivated to participate, a small or biased subset of the target population will participate in the intervention. Bias is of special concern when those enrolled represent only part of the continuum of risk. Selective enrollment may compromise both internal validity (the interpretation of the research results) and external validity (the generalizability of the findings) of intervention trials in primary prevention. This article discusses the effects of partial enrollment and the resultant bias. It suggests several strategies for increasing the enrollment of the target population and examines some of their ethical ramifications. It also stresses the importance of collecting systematic data documenting how the participants in the intervention differ from the target group as a whole.     

Desired control and felt control as mediators of stress in a dental setting

Control-related variables have clearly affected stress responses in previous research (Thompson, 1981). Prior work, however, has primarily emphasized the amount of control that subjects perceive they have. In the three studies reported here, we examined the added predictive utility of assessing subjects' desire for control. Data from all three studies indicate that subjects who have a high desire for control coupled with a low feeling of control are characterized by particularly high degrees of dental distress. These results were found both in settings where patients anticipated immediate dental treatment and where treatment was not imminent. In addition, the results indicate that this "at risk" group reported greater distress before and immediately after actual dental treatment. Furthermore, they remembered their dental treatment as being more aversive 1 week after treatment. The practical implications and theoretical significance of these data are considered.     

Assessing general maladjustment with the MMPI-2

The validities of 7 MMPI-2 (Butcher, Graham, Ben-Porath, Tellegen, & Kaemmer, 2001) measures of general maladjustment were compared using a composite criterion measure based on self-reported symptom severity and clinicians' ratings of symptom severity and level of functioning. Participants were 274 male and 425 female clients at a community mental health center and 105 male and 247 female clients at a university psychological clinic. All MMPI-2 measures were significantly related to the composite criterion measure for both male and female clients in both settings. The mean score on 8 clinical scales (M8) consistently was the best indicator of maladjustment. Although other MMPI-2 measures sometimes added significantly to the variance accounted for in the criterion measure, increments were small and probably not clinically meaningful. However, M8 added significantly and meaningfully to each of the other MMPI-2 measures in predicting maladjustment. Implications for using the MMPI-2 to assess general maladjustment in outpatient mental health settings are discussed.
