Title: Psychology needs a... heterogeneity revolution.
Authors: Linden, Audrey (AUTHOR)
Source: Psychologist. Mar2026, p22-25. 4p. 1 Color Photograph.
Subjects: Heterogeneity, Treatment effectiveness, Demographic characteristics, Participant observation, Research methodology, Counseling, Effect sizes (Statistics), Mental health
Abstract: The article discusses the need to abandon the assumption that psychological interventions have a single, consistent effect size, advocating for a "heterogeneity revolution" in research. It highlights the variability in intervention outcomes, particularly in mental health, where existing studies often fail to account for differences in populations and contexts, leading to ineffective or harmful interventions for certain groups. The author emphasizes the importance of understanding the reasons behind this variability and suggests that incorporating participatory research methods can enhance the relevance and effectiveness of psychological interventions. Ultimately, the article calls for a shift in research practices to better address the diverse needs of different communities. [Extracted from the article]
