Perceived Racism and Mental Health in Black Americans: A Meta-Analysis

Introduction and Research Question

Racism is pervasive in many societies and resists efforts to eradicate it from the cultural practices and mindsets of populations. Among the many negative outcomes of racism, one of the most important is the impact that perceived racism has on the very people against whom the racism is directed or the groups to which they belong. While it is natural to assume that the psychological and physiological outcomes of perceived prejudice have adverse effects on those who experience it, little research exists to demonstrate these relationships comprehensively.

To address this gap, Pieterse et al. (2012) conducted a meta-analytic review of 66 studies (total sample size: 18,140 participants) conducted between January 1996 and April 2011 to better understand the relationship between racism and mental health in Black Americans.

The research question and hypotheses are as follows:

Methodology and Study Selection

R1: What is the magnitude of the relation between perceived racism and mental health among Black Americans?

H0: No relation exists between perceived racism and mental health among Black Americans.

H1: A relation does exist between perceived racism and mental health among Black Americans.

The initial search generated 138 empirical studies, which were further scrutinized for inclusion criteria and sufficient statistical information to productively determine effect sizes. The researchers conducted a literature search using the following inclusion criteria: studies needed to include a specific analysis of indicators of mental health and perceived racism; studies needed to focus on Black Americans living in the United States; and studies had to be dissertations or published in peer-reviewed journals between 1996 and 2011.

Statistical Analysis and Effect Size Measurement

A coding protocol and coder training manual were developed to ensure consistency in data extraction. Trained coders worked with dissertation articles and dissertations, achieving an inter-rater reliability of 90 percent, which strengthened the validity of the aggregated findings.

Five moderator variables were identified and operationalized:

Effect sizes were measured using the Pearson product-moment correlation to indicate positive correlations between perceived racism and mental distress. Using a random effects model, effects from the individual studies were aggregated to determine an overall effect size, with weighted contributions from each study.

Key Findings and Results

The researchers checked for publication bias using a funnel plot, an analytical tool that accounts for the artifact that published works tend to contain larger samples and more significant effect sizes than unpublished findings. This approach strengthens confidence in the meta-analytic findings by identifying potential systematic biases in the literature base.

The aggregated correlation between perceived racism and psychological distress was determined for all 66 studies using a random effects model. The correlation was found to be statistically significant at r = 0.20, confidence interval (CI) 95% [0.17, 0.22]. Egger's regression was not significant (t(64) = 1.01, p = 0.32, 95% CI [0.61, 1.85]), indicating a lack of publication bias. The null hypothesis was rejected, confirming the documented link between perceived discrimination (racism) and mental health in Black Americans.

Moderation analyses revealed that anxiety, depression, and other psychiatric symptoms showed notable associations with perceived racism. In contrast, the association between mental illness and quality of life indicators (such as life satisfaction or self-esteem) was considerably weaker. Moreover, moderation effects were not found for measurement precision, racism scale type, sample type, or publication type, suggesting that the relationship between perceived racism and mental distress was robust across these study characteristics.
