Predictive Testing of Eighteen Year Olds: Counseling Challenges

Genetic counseling of teenagers is challenging and complex. The ability to think abstractly, a sense of self and independence from family all develop during adolescence. Predictive genetic testing counseling protocols presuppose that these qualities exist, requiring the at-risk individual to consider the short and long term consequences of testing as well as their motivations. Eighteen year olds are in transition from adolescence to adulthood; eligible for predictive genetic testing, they may not yet be independent of their family or able to articulate their feelings. This paper presents case studies from the authors' clinical practice to illustrate some of the difficulties faced by genetic counselors when 18 year olds request predictive testing for Hereditary Non-Polyposis Colorectal Cancer. By reflecting upon their experiences with these young adults and their families, the authors' intention is to generate discussion about genetic counseling strategies, particularly for predictive genetic testing, that are both age-appropriate and family-sensitive.     

Dietary restraint, body dissatisfaction, and psychological distress: a prospective analysis

This study uses prospective data from a survey of 1,177 adolescent girls to examine whether emotional eating, binge eating, abnormal attitudes to eating and weight, low self-esteem, stress, and depression are associated with dietary restraint or body dissatisfaction. In analyses that included both restraint and body dissatisfaction as independent predictors, restraint was associated only with more negative attitudes to eating, whereas body dissatisfaction was significantly associated with all the adverse outcomes. These results cast doubt on the proposition that restrained eating is a primary cause of bulimic symptoms, emotional eating, and psychological distress seen in individuals who are trying to control their weight, and rather suggest that body dissatisfaction is the key factor.     

Researchers misunderstand confidence intervals and standard error bars

Little is known about researchers' understanding of confidence intervals (CIs) and standard error (SE) bars. Authors of journal articles in psychology, behavioral neuroscience, and medicine were invited to visit a Web site where they adjusted a figure until they judged 2 means, with error bars, to be just statistically significantly different (p < .05). Results from 473 respondents suggest that many leading researchers have severe misconceptions about how error bars relate to statistical significance, do not adequately distinguish CIs and SE bars, and do not appreciate the importance of whether the 2 means are independent or come from a repeated measures design. Better guidelines for researchers and less ambiguous graphical conventions are needed before the advantages of CIs for research communication can be realized.     

Thought suppression mediates the relationship between negative affect and borderline personality disorder symptoms

The purpose of this study was to examine the relationships among negative affect, childhood sexual abuse (CSA), thought suppression, and diagnostic symptoms of borderline personality disorder (BPD) in a community sample (n=127). Findings suggest that the temperamental variable negative affect intensity/reactivity was a stronger predictor of BPD symptoms than CSA. In addition, results indicated that higher thought suppression mediated the relationship between negative affective intensity/reactivity and BPD symptoms, after controlling for a history of CSA. Overall, findings suggest that (a) negative affectivity may be a better predictor of BPD symptoms than CSA, and (b) chronic efforts to suppress unpleasant thoughts may be a regulation strategy underlying the relationship between intense negative emotions and BPD symptoms.     

Mea culpa: predicting stock prices from organizational attributions

People's causal attributions for events in their lives have been shown to relate to individual and interpersonal outcomes. Groups and organizations also make causal attributions, and this article examines whether their publicly communicated attributions predict organizational-level outcomes. By content analyzing attributions contained in corporate annual reports from 14 companies during a 21-year period, the authors found that organizations that made "self disserving" attributions- internal and controllable attributions for negative events-had higher stock prices 1 year later. The authors argue that claiming personal responsibility for negative events made the organizations appear more in control, leading to more positive impressions.     

Research Report: Students' knowledge of abnormal psychology

The present study aims to compare whether final year psychology students (n = 26) could answer more items on a multiple choice questionnaire (MCQ) correctly on abnormal psychology than prospective psychology candidates (n = 77) and final year engineering students (n = 26). The three groups of students completed MCQs in five different fields of abnormal psychology namely; eating disorders, schizophrenia, anxiety disorders and depression, sexual disorders, and personality and compulsive disorders, respectively. They were also asked to indicate their confidence level in relation to the accuracy of the answers they had given. The results showed that final year psychology students scored higher on levels of accuracy, as well as confidence on all measures compared to the two other groups. On the subject of sexual disorders, engineering students scored higher than prospective psychology students. Implications of the present findings are discussed.     

Figure Preferences in Two Generations of Men: The Use of Figure Drawings Illustrating Differences in Muscle Mass

Using a new set of male figure drawings which(unlike the Stunkard, Sorensen, & Schulsinger, 1983figures) illustrate differing degrees of muscle massrather than body fat, college men and adult men selected their current figure, ideal figure,figure they thought most attractive to women and figurethat they thought would be the ideal for other men.Adult men's choices indicated satisfaction with their current bodies, but college men's selectionsindicated a desire to be larger (partly because theybelieve that a much larger body is what everybody {menand women} finds most attractive). The male body college women find most attractive is largerthan what college men indicate they currently have butsmaller than what the college men want to look like.Adult women chose an ideal male figure which is the same as that which the adult men indicate theyhave. Thus, selections using the new figure drawingsshow a desire for more muscle mass in college men andsatisfaction in adult men, while selections using the Stunkard et al. (1983) figuredrawings indicated satisfaction in college men and adesire for less body fat in the adult men (Rozin &Fallon, 1988). Both sets of figures provide valuableinformation.     

Expression of Fos and Jun Proteins Following Passive Avoidance Training in the Day-Old Chick

It has been shown previously that the immediate-early genes, c-fos and c-jun mRNA are induced in the 1-day-old chick forebrain after one-trial passive avoidance training in which chicks learn to avoid pecking at a bitter-tasting bead. Here, we have studied the expression of their proteins using antibodies to Fos and Jun. Western blotting disclosed two immunoreactive bands for the anti-Fos antibody (47 and 54 kD) and two immunoreactive bands for the anti-Jun antibody (39 and 54 kD). Two hours post-training there was an increase in the number of Fos-positive stained nuclei in right intermediate medial hyperstriatum ventrale (IMHV) (P<0.01), left IMHV (P<0.05), right lobus parolfactorius (LPO) (P<0.025) and left LPO (P<0.05) of birds trained on the bitter bead compared with controls that had pecked a water-coated bead. Staining for Jun protein was significantly greater in the right LPO of trained chicks (P<0.01). Other forebrain regions showed no increase over quiet control levels. The findings are discussed in the context of the cascade of events involved in passive avoidance memory consolidation in the day-old chick.     

Gender Differences in Depression: The Role Played by Paternal Attitudes of Male Superiority and Maternal Modeling of Gender-Related Limitations

A reanalysis of a large multi-generational,predominantly Caucasian sample of adults found a largegender difference in self-reported depression involvinganxiety, appetite and sleep disturbance, and fatigue (anxious somatic depression) butnot in pure depression unaccompanied bymany of these other symptoms, replicating earlierfindings on high school and college samples. Anxioussomatic depression was prevalent among women whosefathers reported attitudes of male superiority and amongwomen whose mothers reported emphasizing the importanceof professional success but feeling that the jobs they held were not respected by others. Anxioussomatic depression, but not pure depression, was foundto be prevalent among women who did not attend collegeand among those who attended college but felt that the jobs they held were not respected byothers.
