Cohort differences in cognitive aging and terminal decline in the Seattle Longitudinal Study

Life span researchers have long been interested in how and why fundamental aspects of human ontogeny differ between cohorts of people who have lived through different historical epochs. When examined at the same age, later born cohorts are often cognitively and physically fitter than earlier born cohorts. Less is known, however, about cohort differences in the rate of cognitive aging and if, at the very end of life, pervasive mortality-related processes overshadow and minimize cohort differences. We used data on 5 primary mental abilities from the Seattle Longitudinal Study (Schaie, 2005) to compare both age-related and mortality-related changes between earlier born cohorts (1886-1913) and later born cohorts (1914-1948). Our models covary for several individual and cohort differences in central indicators of life expectancy, education, health, and gender. Age-related growth models corroborate and extend earlier findings by documenting level differences at age 70 of up to 0.50 SD and less steep rates of cognitive aging on all abilities between 50 and 80 years of age favoring the later born cohort. In contrast, mortality-related models provide limited support for positive cohort differences. The later born cohort showed steeper mortality-related declines. We discuss possible reasons why often reported positive secular trends in age-related processes may not generalize to the vulnerable segment of the population that is close to death and suggest routes for further inquiry.     

Enhancing the Cognitive Vitality of Older Adults

Aging is associated with decline in a multitude of cognitive processes and brain functions. However, a growing body of literature suggests that age-related decline in cognition can sometimes be reduced through experience, cognitive training, and other interventions such as fitness training. Research on cognitive training and expertise has suggested that age-related cognitive sparing is often quite narrow, being observed only on tasks and skills similar to those on which individuals have been trained. Furthermore, training and expertise benefits are often realized only after extensive practice with specific training strategies. Like cognitive training, fitness training has narrow effects on cognitive processes, but in the case of fitness training, the most substantial effects are observed for executive-control processes.     

Revisiting the factor structure of the questionnaire on smoking urges

This study assessed the factor structure of the Questionnaire on Smoking Urges (QSU), a commonly used assessment of cravings for cigarettes, with a sample of smokers presenting for treatment in a smoking cessation trial. On the basis of previous research, three confirmatory factor analytic models were tested. Model 1 hypothesized a 26-item, 2-factor model using the items reported in the original QSU analysis by S. T. Tiffany and D. J. Drobes (1991). Model 2 hypothesized a 12-item, 2-factor model comprised of the 6 most robust items found in each of the 2 factors of the original factor analysis. Using the 12 items from Model 2, Model 3 hypothesized a 12-item, 1-factor model. The 2nd model was found to fit the data best. Reliability was also tested using values obtained in this 2nd model, and these estimates were found to be reasonably good. Future research directions for the QSU are discussed.     

The Importance of Community in a Feminist Analysis of Domestic Violence among American Indians

There are over 500 native communities in the United States alone. Although popular conceptions in the majority culture commonly refer to these as a single American Indian group, native communities are in fact extremely diverse and heterogeneous. Issues of gender, class, and power are discussed from a feminist perspective with an emphasis on the diversity among native communities. Available evidence, while sketchy, suggests that male authority, male restrictiveness, and socioeconomic stress are associated with violence, but that the levels of these factors vary widely across native groups. For example, some native tribes practice matrilineal descent while others are patrilineal. This diversity has far-reaching implications for the community context in which domestic violence occurs. An approach that integrates both feminist and community approaches seems best suited to address the problem of domestic violence in native North America.     

Cross-cultural differences in female university students' attitudes toward homosexuals: a preliminary study

62 Caucasian, 61 Hispanic, and 44 Asian female undergraduates completed the Index of Homophobia by Hudson and Ricketts, seven items from the Attitudes Toward Lesbians and Gay Men Scale by Herek, and three questions on Affectional Orientation toward homosexuals from D'Augelli and Rose. Overall, familiarity with homosexuals as measured by self-reported number of homosexual friends correlated negatively with scores on the homophobia measures, but there were no significant differences among the groups' reported number of homosexual friends. Asian students scored significantly higher on the homophobia measures than Caucasian students. Both Asian and Hispanic students endorsed the statement significantly more often than Caucasian students that the university would be better if only heterosexuals attended. No significant differences in scores were found regarding attitudes toward lesbians versus gay men.     

Anxiety sensitivity in six countries

In the present study, the Anxiety Sensitivity Index-Revised (ASI-R; ) was administered to a large sample of persons (n=2786) from different cultures represented in six different countries: Canada, France, Mexico, The Netherlands, Spain, and the United States. We sought to (a) determine the factor structure and internal consistency of the ASI-R and (b) examine the correlations of the measure with psychiatric symptoms and personality dimensions in a single European non-English speaking country (The Netherlands). Partially consistent with the original hypothesis, the underlying structure of the anxiety sensitivity construct was generally similar across countries, tapping fear about the negative consequences of anxiety-related physical and social-cognitive sensations. Lower-order factors were moderately to strongly correlated with one another and showed good internal consistency. The observed lower-order ASI-R factors correlated with established psychiatric symptoms and with the personality trait of neuroticism. Partial correlations indicated that both factors are useful in accounting for variance in symptom measures. We discuss the results of this investigation in relation to the cross-cultural assessment of the anxiety sensitivity construct.     

Perfectionism is multidimensional: a reply to Shafran,Cooper and Fairburn

provided a cognitive-behavioural analysis of perfectionism that focused primarily on self-oriented perfectionism. They argued against studying perfectionism from a multidimensional perspective that they regard as inconsistent with prior work on perfectionism as a self-oriented phenomenon. We respond to by offering historical, empirical, and theoretical support for the usefulness and the importance of a multidimensional model of perfectionism involving both intrapersonal processes and interpersonal dynamics. It is concluded that a multidimensional approach to the study of perfectionism is still warranted.     

Distance-Delivered Parent Training for Childhood Disruptive Behavior (Strongest Families™): a Randomized Controlled Trial and Economic Analysis

Disruptive behavior disorders are prevalent in youth, yet most children with disruptive behavior do not have access to timely, effective treatment. Distance-delivered service (e.g., via telephone, Internet) can overcome several barriers to care. This study tested the effectiveness of a 12-week parent training program, Strongest Families? Parenting the Active Child, delivered via written material, skill-based videos, and telephone coaching sessions, as compared to usual care in reducing child externalizing behavior. Participants were 172 primary caregivers of a 6- to 12-year-old (29% girls; M age?=?8.5 years) recruited from community children’s mental health clinics. Participants were randomized to either Strongest Families? or usual care and completed measures of child externalizing behavior, parenting practices, parent distress, and intervention services consumed at baseline and 5-, 10-, 16-, and 22-months post-baseline. Growth curve analysis showed significant reductions in externalizing behavior in both conditions over time. Improvements were significantly greater at 10 months in the Strongest Families? condition (d =?0.43). At 22 months, however, the differences were not significant and small in magnitude (d =??0.05). The intervention decreased inconsistent discipline significantly more than usual care. Parents in both conditions showed significant reductions in distress. We also conducted a cost-effectiveness analysis to assess the value for money of the Strongest Families? program versus usual care. Distance parent training is a promising way to increase access to, and reduce costs associated with, mental health care for families with a child with disruptive behavior.     

The relationship between conformity to gender norms,sexual orientation,and gender identity for sexual minorities

The current study examined how dimensions of masculinity and femininity were expressed for sexual minorities. Cluster analysis was used to determine the number of latent classes for conformity to masculine and feminine norms for sexual minorities. A four-class solution was the best fit to the data. Cluster 1 (labeled Relating to others through equality and caring, n = 41) was characterized by low dominance and power over women and high involvement with kids and have nice relationships norms. Cluster 2 (labeled Relating to others through avoidance and misogyny, n = 38) was characterized by low risk-taking and have nice relationships and high power over women and disdain for homosexuality. Cluster 3 (labeled Relating to others through power, n = 34) was characterized by high winning, pursuit of status, and appearance and low modesty. Cluster 4 (labeled Relating to others through sex, n = 27) was characterized by low involvement in romantic relationships and sexual fidelity while endorsing high playboy attitudes. Results indicate that conforming to gender norms tends to follow categories of interpersonal beliefs and behaviors rather than being based in gender identity or sexual orientation. Implications of the results for future research and clinical practice are examined.     

Re-enactments in their developmental context

The power of the repetition compulsion is felt in an especially keen way during re-enactments within psychodynamic psychotherapy. In this paper, the authors recommend greater attention to the developmental aspects of re-enactments as providing valuable information about the affective character of the crisis being brought to life in the treatment. Specifically, the authors suggest that the current developmental stage of the patient influences the experience and expression of the core developmental conflict that lies at the heart of the re-enactment in the treatment dyad. Re-enactments in childhood, adolescence and young adulthood, as well as at midlife and in the later years, each have different signatures. Thus, increased knowledge and awareness of both developmental stage and developmental core conflict is important for the following reasons: It provides a firmer theoretical foundation for understanding what is, by definition, a formidable moment in treatment; it adds another dimension and thus enhanced flexibility to the clinician’s clinical stance during a time of greater countertransference potential; and it adds to the theoretical perspective that the compulsion to repeat functions, at least in part, as an attempt to master an intrapsychic, affectively charged, previous experience of defeat. Clarifying the developmental nature of re-enactments for both patient and therapist can serve an orienting function during what is often a confusing and destabilizing time in the treatment relationship, and it can help differentiate developmentally appropriate behaviour from re-enacted conflict.
