Clinical utility of the MMPI in the evaluation of adolescent suicide attempters

MMPI profiles of female adolescents hospitalized on a general pediatrics floor following a suicide attempt were compared to a control group of medically hospitalized, female adolescents referred for psychiatric evaluation. The suicide attempters had only a lower score on the K scale when compared to the control group. Results do not suggest that a single MMPI profile differentiates suicide attempters from a comparison group of adolescents with emotional difficulties. Implications of these findings are discussed.     

Depressive characteristics of physically abused children

Physically abused and nonabused children were compared on child-completed measures of depression, hopelessness, self-esteem, and locus of control. Results indicated that, in comparison with nonabused controls, abused children evidenced more depressive symptoms, heightened externality, lower self-esteem, and greater hopelessness about the future. Group differences in depressive symptomatology were not accounted for on the basis of differences in age, sex, race, gender, IQ, or socioeconomic status. Results replicate the results of Kazdin, Moser, Colbus, and Bell (1985) derived from a sample of physically abused psychiatric inpatients and extend the generality of these findings to abused children of nonpatient status. Implications of the findings for clinical interventions, theoretical models of child depression, and future research are discussed.The authors wish to thank Alvin Hadley and the staff of Franklin County Children Services.Appreciation is also extended to Dr. Charles Wenar.     

Spelunking as a manifestation of a counterclaustrophobia

Material is presented from the case history of a patient whose interest in spelunking (cave exploration) was found to be an unconscious expression of a type of counterclaustrophobia. Both oedipal and preoedipal determinants of the claustrophobic anxieties are delineated. Of particular note in this instance is the testicular element in the genesis of the patient's claustrophobia. His confusion of the movements of his testicles into his inguinal canals during childhood defecation with the movements of the feces themselves lent an special intensity to his fear of being flushed away from the mother by an expulsive anal birth from the claustrum. Childhood anxiety aroused when his testicles would become trapped in the inguinal canals was an important forerunner of the adult fear of being trapped in confined spaces. A counterphobic element of the spelunking per se was his enjoyment in hanging suspended by a rope in caves. In this manner, he was able to act out (by virtue of his body-testicle equation) his identification with, and control over, the disappearing testicles in the setting of a claustrophilic union with the mother.     

Surface form and the spacing effect

Deficient processing theories of the spacing effect attribute poor recall of massed-repeated items to a failure to process one or both of the presentations fully. An implication of this approach is that anything that increases the probability that a repetition will receive full processing, or conversely, anything that decreases the probability that the item will be recognized as a repetition, should improve memorability of the item. The present set of experiments tested this prediction by manipulating the surface structure of repeated sentences. On the basis of previous research, it was assumed that memory for surface structure of sentences decays rapidly, and hence can contribute to initial identification of repetitions only at short spacings. Because this manipulation should hinder recognition of repetitions as repetitions, it was expected to induce full processing of massed repetitions, and thus facilitate recall of these items. This prediction was supported. When sentences were repeated verbatim (Experiment 1) or by the same speaker (Experiment 2), the typical spacing effect was obtained. However, when the surface structure or speaker changed at time of repetition, massed repetitions were recalled nearly as well (Experiment 1) or as well (Experiment 2) as their spaced counterparts.     

A note on the standard length of a test

This paper describes a relationship between the variance-covariance matrix of test items and Woodbury's concept of the standard length of a test. An index of item-test relationship is described in standard length terms. The sum of these indices for the items in a test is equal to the square of Jackson's coefficient of sensitivity.     

Grandparents Affected by Parental Divorce: A Population at Risk?

When parents divorce, grandparents who have bonded with grandchildren may be affected, particularly when denied visitation. In this article the author reviews normative aspects of grand-parenthood and how grandparents are affected by parental divorce. Legal and ethical issues and counseling interventions are discussed.     

Regression analyses of repeated measures data in cognitive research

Repeated measures designs involving nonorthogonal variables are being used with increasing frequency in cognitive psychology. Researchers usually analyze the data from such designs inappropriately, probably because the designs are not discussed in standard textbooks on regression. Two commonly used approaches to analyzing repeated measures designs are considered in this article. It is argued that both approaches use inappropriate error terms for testing the effects of independent variables. A more appropriate analysis is presented, and two alternative computational procedures for the analysis are illustrated.     

Polygraph Testimony and Juror Judgments: A Comparison of the Guilty Knowledge Test and the Control Question Test1

The present experiment investigated the impact of the Control Question Test (CQT) and the Guilty Knowledge Test (GKT) on the verdicts of mock jurors. Although studies have indicated that polygraph evidence has little influence on jurors' verdicts (Cavoukian & Heselgrave, 1980; Spanos, Myers, Dubreuil, & Pawlak, 1992–1993), no research has previously distinguished between the different types of polygraph tests and their impact on juror verdicts. In the present study, jurors were shown a videotape of a simulated rape-murder trial that contained either CQT polygraph evidence, GKT polygraph evidence, or no polygraph evidence. No differences were found among the 3 conditions for either jury verdicts or individual juror verdicts, and jurors tended to rate both forms of polygraph testimony below other forms of equally suspect evidence, such as eyewitness testimony, in its influence on their decision-making process.
