Stress, reactivity, and immune function in healthy men.

We examined the effects of acute psychological stress on lymphocyte proliferation and circulating levels of interleukin-1 and -2. Healthy men were exposed to two viewings of a gruesome surgery film and were asked to recall details of the film twice during a 30-min period. These subjects were compared to a nonstress control group. Lymphocyte proliferation to the mitogen concanavalin A (Con A; 5 micrograms/ml) was decreased during and after exposure to the stressor when compared to the control group. This decrease was more pronounced in subjects exhibiting greater blood pressure reactivity while viewing the film than in subjects showing smaller blood pressure responses. None of the other immunological measures was significantly affected by the stressor. Cortisol was not correlated with lymphocyte responsiveness. Possible explanations for these results and implications for further research are discussed.     

THE REDUCTION OF STEALING IN SECOND GRADERS USING A GROUP CONTINGENCY1

Three classes of second graders served as subjects in this study of the effects of two types of intervention programs upon stealing: (1) an antistealing lecture with no specific contingency implied, and (2) a direct group contingency applied, whereby children were rewarded with (a) extra free time for no thefts, (b) allowed normal free time if stolen items were returned, and (c) punished with loss of free time if stolen items were not returned. A multiple-baseline design across the three classes showed the group contingency to be effective in reducing stealing behavior; the anti-stealing lecture was ineffective.     

The Inventory of Children's Individual Differences: Development and Validation of a Short Version

The development of programmed, actuarial interpretation of personality tests, especially the MMPI, is discussed. The presentation seeks to present a synoptic overview of the topic, including its more important trends, apparent present status, and possible consequences. Several commercially available systems are described, and an example of the output of each of three of them, in interpreting the same MMPI protocol, is presented for comparative illustration.

Modeling the Information Preferences of Parents of Children with Mental Health Problems: A Discrete Choice Conjoint Experiment

Although materials informing parents about children’s mental health (CMH) problems can improve outcomes, we know relatively little about the design factors that might influence their utilization of available resources. We used a discrete choice conjoint experiment to model the information preferences of parents seeking mental health services for 6 to 18 year olds. Parents completed 30 choice tasks presenting experimentally varied combinations of 20 four-level CMH information content, transfer process, and outcome attributes. Latent class analysis revealed three segments with different preferences. Parents in the Action segment (43%) chose materials providing step-by-step solutions to behavioral or emotional problems. They preferred weekly meetings with other parents and coaching calls from a therapist. The Information segment (41%) chose materials helping them understand rather than solve their child’s problems. These parents were more sensitive to logistical factors such as receiving information in groups, the location where information was available, the modality in which the information was presented, and the time required to obtain and use the information. The Overwhelmed segment (16%) reported more oppositional and conduct problems, felt their children’s difficulties exerted a greater adverse impact on family functioning, and reported higher personal depression scores than those in the Action or Information segments. Nonetheless, they did not choose information about, or solutions to, the problems their children presented. Simulations predicted that maximizing utilization and realizing the potential benefits of CMH information would require knowledge transfer strategies consistent with each segment’s preferences.

The importance of similarity in the marital relationship.

Concepts such as "agreement," "consensus," "understanding," and "shared meaning" are very familiar to clinicians. It is argued in this article that similarity in perceptions between spouses is a crucial dimension of the family system underlying these concepts. Findings are presented that support the idea that families vary along a dimension of similarity of perceptions, with more functional families characterized by high similarity between spouses' perceptions of their marriage and their family. In addition, the structure of this similarity was stable over 2 years and little change occurred in the mean level of similarity. Of three sets of predictor variables--psychological stress, marital cohesion, and structural variables--marital cohesion was the most powerful predictor of marital similarity. The importance of similarity of perceptions between family members in clinical work is discussed.     

Clues to aural discrimination

Five measures of the items of the Multiple-Choice Intelligibility Test were obtained: apparent aural similarity of the four words available to a listener on hearing a stimulus, interconsonantal differences among the prevocalic portions of these words, phonemic discrepancies among these words, distinctive feature differences among these words, and the pooled discrimination score of the four words that were available to the responder on hearing the stimulus. The last score was made the target in a multiple correlation problem, and the relative contribution, combined and separately, of the four remaining measures to the target measure was determined. These four measures accounted for approximately 45% of the variance among the scores of discrimination. The strongest contributors were apparent aural similarity of the available responses and the phonemic discrepancy among the available responses.     

The Inventory of Children's Individual Differences: development and validation of a short version

As more researchers utilize the Five-factor model (FFM) of personality with children and adolescents, the need for instruments designed specifically for use with children and adolescents increases. In the United States, the 108-item Inventory of Children's Individual Differences (ICID; Halverson et al., 2003), has provided researchers with an age and culture neutral instrument designed specifically to assess the FFM of personality in children and adolescents, ages 2 to 15, using parental, nonparental, or self-reports. This article presents a shorter, 50-item version of the ICID (the ICID-S) that maintains the levels of validity and reliability previously established for the full instrument.
