In the current article, we examine mattering to others as a relational resource and discuss how feelings of not mattering are uniquely implicated in addiction and substance use. We describe the mattering construct and how it is conceptualized, and we comprehensively review existing evidence based primarily on research with adolescents that links feelings of not mattering with addictive tendencies in general, and specific tendencies (e.g., excessive drinking and drug use and excessive social media use). A central premise of this article is the need to take race and ethnicity into account when considering the potential link between feelings of not mattering and substance use among young people with minority status and various ethnicities who may be especially prone to feeling marginalized and insignificant as a result of adverse experiences reflecting being ostracized and not socially accepted. Potential models of drinking and addictive tendencies that can easily incorporate the mattering construct are also outlined to underscore the conceptual relevance of feelings of not mattering to others. Mattering is also considered in terms of how internalization (i.e., not mattering to oneself) potentiates impulsive and risky behavior. Our article concludes with discussion of the implications for treatment and prevention in addiction and substance use and directions for future research that should further illuminate the role of feelings of not mattering to others and not mattering to oneself.
