Growth in infancy and childhood and hospitalization for personality disorders in adulthood: the Helsinki Birth Cohort Study

This study examined the associations between infant and childhood growth and severe personality disorders. Among 4,689 men and 4,200 women of the Helsinki Birth Cohort Study 1934-1944, 81 men and 68 women had been hospitalized with an ICD (-8, -9, -10) diagnosis of personality disorder in adulthood. Among men, slower gain in BMI between birth and 6 months, faster gain in weight and BMI between 6 months and 1 year, and slower gains in them between 7 and 11 years of age predicted an increased risk of hospitalization for personality disorders. Thinness at 6 months and again at 11 years also showed significant association with personality disorders among men. Among women, slower gain in height between 2 and 7 years predicted hospitalization for personality disorders. Our findings show the importance of early growth as a vulnerability factor of personality disorders severe enough to justify hospitalization.     

Assessing women's responses to sexual threat: validity of a virtual role-play procedure

This study evaluated the validity of a role-play procedure that uses virtual reality technology to assess women's responses to sexual threat. Forty-eight female undergraduate students were randomly assigned to either a standard, face-to-face role-play (RP) or a virtual role-play (VRP) of a sexually coercive situation. A multimethod assessment strategy was used to evaluate the efficacy of the role-play procedure in creating a realistic and immersive situation. Consistent with our hypotheses, women in the VRP condition exhibited greater negative affect and immersion than women in the RP condition. In addition, the level of assertive refusal in the VRP, but not the RP, condition differentiated between women with and without a prior history of sexual victimization. These findings provide evidence of the validity of a virtual role-play procedure for assessing women's responses in sexually threatening situations.     

Trajectories of emotional well-being in mothers of adolescents and adults with autism

Raising an adolescent or adult child with a developmental disability confers exceptional caregiving challenges on parents. We examined trajectories of 2 indicators of emotional well-being (depressive symptoms and anxiety) in a sample of primarily Caucasian mothers (N = 379; M age = 51.22 years at Time 1) of adolescent and adult children with an autism spectrum disorder (ASD; M age = 21.91 years at Time 1, 73.2% male). We also investigated within-person associations of child context time-varying covariates (autism symptoms, behavior problems, residential status) and maternal context time-varying covariates (social support network size and stressful family events) with the trajectories of emotional well-being. Data were collected on 5 occasions across a 10-year period. Average patterns of stable (depressive symptoms) and improved (anxiety) emotional well-being were evident, and well-being trajectories were sensitive to fluctuations in both child and maternal context variables. On occasions when behavior problems were higher, depressive symptoms and anxiety were higher. On occasions after which the grown child moved out of the family home, anxiety was lower. Anxiety was higher on occasions when social support networks were smaller and when more stressful life events were experienced. These results have implications for midlife and aging families of children with an ASD and those who provide services to these families.     

Adolescent Psychopathy and the Five Factor Model: Domain and Facet Analysis

Given the consideration of callousness as a specifier for Conduct Disorder in the DSM-V, it seems imperative that researchers continue to investigate this personality style in adolescents to determine both its applicability and utility. The present study examined the Youth Psychopathic traits Inventory (YPI; Andershed et al. 2002) and the Interpersonal Adjective Scale Revised-Big 5 (IASR-B5; Trapnell and Wiggins 1990a, b) psychopathy scales in relation to the Five Factor Model (FFM) of personality. Using a sample of adolescent offenders (N = 145), the YPI and IASR-B5 psychopathy scales showed adequate reliability and strong inverse bivariate relations with the FFM domains of Agreeableness (−A) and Conscientiousness (−C). Multivariate analyses, at the facet level, revealed that Tendermindedness (−A) and Assertiveness (+E) explained the association between FFM facets and the YPI, whereas Altruism (−A), Modesty (−A), Straightforwardness (−A), Assertiveness (+E), Warmth (−E), and Deliberation (+C) all uniquely contributed to the IASR-B5 psychopathy scale. Both measures were linked with general and violent recidivism. The authors discuss the implications of these findings in terms of the use of personality to help describe conduct problem youth and the need for future research in this important area.     

Ethical analysis of research partnerships with communities

Community-researcher partnerships constitute one of the most important recent developments in biomedical ethics. The partnerships protect vulnerable communities within which research is conducted and help ensure that the communities benefit from the research. At the same time, they embody deep, core values about the social nature of persons and the value of community that significantly modify the radical individualism too often associated with the prevailing concepts of autonomy and respect for persons. This article examines the burgeoning literature on community-researcher partnerships to identify the main ways of thinking ethically about the obligations of investigators and the roles and rights of communities in scientific research. The paper helps to uncover the deep commonalities and differences that mark the current debate in this emerging arena of research ethics, a debate over the social nature of persons that is beginning to influence the understanding of other bioethical issues.     

Parrots are "more human" than chickens

Analysis of an Internet database of pets' names showed owners were more likely to give anthropomorphic names to pets living within homes than those living outside.     

Gender Related Naming Practices: Similarities and Differences Between People and their Dogs

We compared final written letters and spoken phonemes and syllable length in the names of male (N = 250) and female (N = 197) Golden Retrievers to determine if the same gender-stereotyping trends occurring in humans also appeared in dog names. Names were taken from a website of the most popular Golden Retriever names in English speaking countries. Both male and female dogs had names ending in letters and phonemes characteristic of their respective human male and female counterparts. Female dogs had more syllables in their names than male dogs and a higher percentage of male dogs had one syllable names. We conclude that the similarities between human and dog naming practices reflect a pervasive gendered naming phonology.     

Gender identity and adjustment in black, Hispanic, and white preadolescents

The generality of S. K. Egan and D. G. Perry's (2001) model of gender identity and adjustment was evaluated by examining associations between gender identity (felt gender typicality, felt gender contentedness, and felt pressure for gender conformity) and social adjustment in 863 White, Black, and Hispanic 5th graders (mean age = 11.1 years). Relations between gender identity and adjustment varied across ethnic/racial groups, indicating that S. K. Egan and D. G. Perry's model requires amendment. It is suggested that the implications of gender identity for adjustment depend on the particular meanings that a child attaches to gender (e.g., the specific attributes the child regards as desirable for each sex); these meanings may vary across and within ethnic/racial groups. Cross-ethnic/racial investigation can aid theory building by pointing to constructs that are neglected in research with a single ethnic/racial group but that are crucial components of basic developmental processes.     

Symbolic significance of initials on longevity

The longevities of deceased major league baseball players who died prior to 1950 (N=3835) and whose initials formed acronyms, words, or names with "positive" or "negative" affect, as rated a priori by two judges, were compared with those for a group of neutral controls matched for birth year and career length, using the Berkeley standardized mortality tables. Players (n=11) with positive initials, e.g., A.C.E., lived a mean of 13 years longer than players (n=30) with negative initials, e.g., D.E.D., or players with neutral initials (n=864). These results corroborated a previous study and suggest positive name symbols are associated with increased longevity in this sample.
