Verbal Working Memory as a Longitudinal Mechanism of Vocabulary Problems in Preschoolers with ADHD

Elucidation of early potential risk factors of Attention-Deficit/Hyperactivity Disorder (ADHD) is important to allow for early identification of ADHD and targeted early intervention for children with ADHD. Delayed language skills, particularly poor vocabulary, is an early-developing potential risk factor that is thought to be involved in developmental pathways to ADHD; however, mechanisms explaining the relationship between poor vocabulary skills and ADHD symptoms are unclear and warrant investigation. The present study examines the relationship between poor vocabulary skills and ADHD symptoms by testing cognitive mechanisms, namely verbal working memory (WM), that might account for this link. Participants were 109 young children between the ages of three and six and their primary caregivers. Diagnostic information on ADHD symptoms was available from parents and teachers/daycare providers via standardized rating forms. Vocabulary skills and WM were measured through child performance on laboratory tasks. Mediation analyses found poor verbal working memory significantly partially explained the vocabulary-ADHD association for both parent and teacher-rated ADHD symptoms. Further, effects of verbal WM on the association between poor vocabulary and increased ADHD symptoms largely held at one-year follow-up. Development of early interventions targeting verbal WM may be a promising new direction for early ADHD intervention work.     

Stress and coping among gay men: age and ethnic differences

Previous studies suggest that perceived stigmatization of sexual minority status, ethnicity, and age are associated with negative mental health outcomes, and other studies suggest that coping styles may influence these outcomes. However, no studies have examined these relationships among gay men of varying ethnicities and age groups. Three hundred eighty-three Black and White, younger, middle-aged, and older adult gay men completed measures of perceived stigmatization, coping style, and mental health outcomes. Black older adult gay men reported significantly higher levels of perceived ageism than the older White group, significantly higher levels of perceived racism than the younger Black group, significantly higher levels of homonegativity than the younger Black and the White groups, and were more likely to use disengaged coping styles than White gay men. However, Black older adult gay men did not experience significantly higher levels of negative mental health outcomes. Results suggest that further research should examine how older Black gay men, who perceive higher levels of stigma while reporting greater use of less effective coping styles, do not appear to be experiencing more negative mental health outcomes as a result.     

Incremental validity of the Psychopathy Checklist facet scores: predicting release outcome in six samples

The incremental validity of the 4 facet scores (Interpersonal, Affective, Lifestyle, Antisocial) of the Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991, 2003) and the Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) was evaluated in 6 forensic/correctional samples with average follow-ups ranging from 20 weeks to 10 years. Results indicated that whereas Facet 4 (Antisocial) achieved incremental validity relative to the first 3 facets (Interpersonal, Affective, and Lifestyle) in predicting recidivism in all 6 samples, a block of the first 3 facets achieved incremental validity relative to the 4th facet in only 1 sample. Thus, although there was consistent support for the incremental validity of Facet 4 above and beyond the first 3 facets, there was minimal support for the incremental validity of Facets 1, 2, and 3 above and beyond Facet 4. The implications of these findings for the psychopathy construct in general and the PCL-R/SV in particular are discussed.     

Contextual Adult Life Span Theory for Adapting Psychotherapy with Older Adults

Our aging population is growing in size and diversity. To integrate different views on aging and make explicit the role of culture as a contextual factor, we modified Knight’s (Psychotherapy with older adults, 2004) Contextual, Cohort-based, Maturity, Specific Challenge (CCMSC) model of psychotherapy with older adults into the Contextual Adult Lifespan Theory for Adapting Psychotherapy (CALTAP). This article describes various components of the CALTAP, which serves as a meta-theoretical framework in guiding an integrated psychotherapy approach for the aging population. The interaction between environmental factors like cohort differences and socio-cultural contexts and individual factors such as maturation and age-related specific challenges not only shapes the experience and presentation of older adults in clinical settings, but also highlights special considerations in adapting psychotherapy for older adults.     

An investigation of the effects of dog visits on depression,mood, and social interaction in elderly individuals living in a nursing home

The present study investigated the effects of weekly dog visits on depression scores, mood, and social interaction in elderly individuals living in a nursing home. Five elderly residents participated in baseline assessments for 4–8 weeks and then received weekly dog visits for 6 weeks. Assessments, consisting of weekly observations of social interaction and paper and pencil measures of mood and depression, continued during the dog visits. The effect of dog visits was evaluated in a multiple baseline across participants design. Dog visits did not improve depression scores, mood (with the exception of one resident), or social interaction (with the exception of one resident). Residents did interact with the dog during the visits, however, and reported that they enjoyed the visits. These results show that dog visits do not always have therapeutic effects and suggest the need for further research in the area before the beneficial effects of dog visits can be substantiated.

He's a Laker; She's a “Looker”: The Consequences of Gender-Stereotypical Portrayals of Male and Female Athletes by the Print Media

Although an extensive qualitative literature shows that coverage of women's sport often focuses on female athletes' attractiveness (to the exclusion of their athleticism), there is a dearth of quantitative research examining exactly what effect this coverage has on people's perceptions of athletes. As part of a 2 (Gender of the Athlete: Female or Male) × 2 (Gender of the Participant: Female or Male) × 2 (Focus of the Article: Physical Attractiveness or Athleticism) between-subjects design, 92 predominantly White undergraduates (40 men, 52 women) read a fictitious newspaper profile about an Olympic athlete in which the article focused on the athlete's attractiveness (as coverage of female athletes often does) or on the athlete's athleticism (as coverage of male athletes often does). Interestingly, participants neither had favorable impressions of nor liked articles about female and male athletes when attractiveness was the main focus of an article. These findings suggest that the media should be cognizant of the harmful and erroneous impressions that can result from portraying athletes in terms of their personal attributes rather than their athletic accomplishments.     

Factor Structure of the Burden Interview

Zarit's Burden Interview is the most commonly used measure of burden among family caregivers for demented older adults, but has been criticized for its diverse item content and lack of correspondence to theoretically based multidimensional burden scales. The factor structure of this measure of burden was examined in a sample of 220 family caregivers of demented elderly. The implied 1-factor model and a 2-factor model proposed in the literature were not good fits to the data. Fourteen of the 21 nonglobal items were found to tap three underlying factors of Embarrassment/Anger, Patient's Dependency, and Self-criticism. This factor structure was replicated in a second sample of 108 caregivers. The relationship of these factors to latent factors identified in other multifactorial burden scales suggests a greater degree of convergence across measures than has been assumed.     

Family and Neighborhood Fit or Misfit and the Adaptation of Mexican Americans

In this study, a person-environment fit model was used to understand the independent and combined roles of family and neighborhood characteristics on the adjustment of adults and children in a sample of 750 Mexican American families. Latent class analysis was used to identify six qualitatively distinct family types and three quantitatively distinct neighborhood types using socioeconomic and cultural indicators at each level. The results showed that members of single-parent Mexican American families may be particularly at-risk, members of the lowest-income immigrant families reported fewer adaptation problems if they lived in low-income neighborhoods dominated by immigrants, members of economically successful immigrant families may be more at-risk in integrated middle class neighborhoods than in low-income neighborhoods dominated by immigrants, and members of two-parent immigrant families appear to be rather resilient in most settings despite their low socioeconomic status.     

Inspection time and everyday functioning: A longitudinal study

We tested whether level and/or changes in inspection time (IT) in an elderly sample (70–85 years at baseline) predicted future independence in everyday functioning, independent from chronological age. Sixty-eight participants were initially assessed on IT and cognitive abilities in 2003, reassessed on IT in 2005, and then completed the Everyday Problems Test, a test of independence in everyday living, in 2008. Controlling for age, lower fluid reasoning at baseline (Raven’s-subset) and slowing IT over 18 months independently predicted poorer everyday functioning in 2008, together accounting for one-third variance. This supports the proposition that IT has utility as a biomarker for less favourable ageing.
