Abstract

Reports an error in "I am what I am: A meta-analysis of the association between substance user identities and substance use-related outcomes" by Kevin S. Montes and Matthew R. Pearson (Psychology of Addictive Behaviors, 2021[May], Vol 35[3], 231-246). In the article (https://doi.org/10.1037/adb0000721), the affiliation names for the authors were incorrect. The correct affiliation names are Department of Psychology, California State University, Dominguez Hills, for Kevin S. Montes; and Center on Alcohol, Substance Use, & Addictions, University of New Mexico, for Matthew R. Pearson. (The following abstract of the original article appeared in record 2021-33942-001.) Objective: Research indicates that a substance user identity (i.e., drinking, smoking, and marijuana identity) is positively correlated with substance use-related outcomes (e.g., frequency, quantity, consequences, and disorder symptoms). The current study aimed to meta-analytically derive single, weighted effect size estimates of the identity-outcome association as well as to examine moderators (e.g., substance use type, explicit/implicit assessment, demographic characteristics, and research design) of this association.

METHOD: Random effects meta-analysis was conducted on 70 unique samples that assessed substance user identity and at least one substance use-related outcome (frequency, quantity, consequences, and/or disorder symptoms), and provided the necessary information for effect size calculations.

RESULTS: Substance user identity was found to be a statistically significant moderate-to-large correlate of all substance use-related outcomes examined in the current study (r (w) =.365, p <.001, r(w)² =.133). The strongest associations were observed between identity and disorder symptoms (alcohol) and frequency of substance use (tobacco or marijuana). In terms of moderators of the identity-outcome association, the link between explicit drinking identity and alcohol use-related outcomes appeared to be stronger in magnitude than the relationship between implicit drinking identity and alcohol use-related outcomes; however, this difference appears to be largely due to the finding that implicit measures have lower reliability. The strongest identity-outcome association was observed among younger individuals.

CONCLUSIONS: Substance user identity is clearly an important correlate of substance use-related outcomes and this association is stronger among younger individuals. Additional theoretical, empirical, and intervention research is needed to utilize knowledge gleaned from the current study on the identity-outcome association.
