Race/Ethnic Differences in Social Resources as Cognitive Risk and Protective Factors

Overall social network size, often the sum of common lifetime relationships, including children, family, and friends, has been linked to cognitive impairment and Alzheimer’s Disease. However, little research has examined the association between network size composition and cognitive function in middle-aged and older adults in the context of race/ethnicity. We investigated the associations between the number of close children, family, and friends independently with executive function (EF) and memory across a subsample of non-Hispanic Black, Hispanic, and non-Hispanic White participants who completed the Health and Retirement Study Harmonized Cognitive Assessment Protocol (N = 2,395). We found that network size composition was more closely linked to EF than memory and that these associations varied by race/ethnicity. Specifically, the strongest associations existed between EF and quadratic estimates of the number of close children of non-Hispanic Black participants, and number of close family members for Hispanic participants. Among Black participants, a curvilinear relationship indicated that two close children were associated with greater EF, while a smaller or larger number of close children were associated with lower EF. On the other hand, among Hispanic participants, higher EF was associated with fewer (0–1) and greater (4-5+) numbers of family member contacts. Overall, these results indicate that examining children, family, and friends independently may be more useful than the common practice of aggregation of overall network size, especially in the context of race/ethnicity.     

In defense of the Ethics Code: a comment on O’Donohue (2019)

ABSTRACT

This article is a commentary on O’Donohue’s2019 37-point critique of the American Psychological Association Ethical Principles of Psychologists and Code of Conduct ([Ethics Code] 2017). In this brief paper, we respond to the article by addressing our most important disagreements with O’Donohue’s arguments as well as areas of agreement. While we disagree with many of O’Donohue’s points, we also view his critique as being important and timely given that the 2018 APA Ethics Task Force is currently exploring potential revisions to the Code.
