Objective: We evaluated the effect of perceived discrimination, optimism, and their interaction on health care utilization among African American adults with sickle cell disease (SCD).
Methods: Measures of optimism and perceived discrimination were obtained in 49 African American SCD patients. Multiple regression analyses controlling for sex and age tested effects of optimism and perceived discrimination on the number of emergency department visits (ED) and number and duration of hospitalizations over the past year.
Results: A perceived discrimination-optimism interaction was associated with number of emergency departments visits (b = .29, p = .052), number of hospitalizations (b = .36, p = .019), and duration of hospitalizations (b = .30, p = .045) such that those with high perceived discrimination/high optimism had the greatest health care utilization.
Conclusions: African American SCD patients with high perceived discrimination/high optimism had greater health care utilization than patients who reported either low perceived discrimination or low optimism. This study suggests that patient personality and coping styles should be considered when evaluating the effects of stress on SCD-related outcomes.

Objectives: Ageism occurs across the world, with negative consequences for individuals and societies. In 2016, WHO received a mandate from its Member States to lead the global campaign to combat ageism. To monitor, evaluate, and build evidence for reducing ageism, the availability of a brief, reliable and valid set of indicators of ageism experiences that can be used globally is essential.

There is a crucial need to more deeply understand the impact and etiology of bias toward persons with developmental disabilities (PWDD). A largely unstudied area of concern and possible intervention is the portrayal of PWDD in medical education. Often, medical photographs portray PWDD with obscured faces, emotionless, and posed in an undignified way.

Background: Frailty is a recognisable clinical measure of impaired physiological reserve and vulnerability to adverse outcomes that is validated among patients with kidney disease. Practice patterns reveal inconsistent use of objective frailty measures by nephrologists, with clinicians prioritising subjective clinical impressions, possibly risking misclassification and discrimination.
Aims: The aim of this study was to examine correlations between subjective and objective measures of frailty in a cohort of patients attending routine nephrologist review.

With the popularity of the internet, cyberbullying has emerged as an increasingly serious social issue, particularly affecting college students' behavioral health. This study explores the relationship between perceived discrimination and cyberbullying, as well as the mediating role of self-esteem and the moderating role of self-compassion (SC) in this relationship. Using a longitudinal design, data were collected from 892 Chinese college students (414 females, 478 males) in two waves spanning 1 year.
