Substance misuse prevention: addressing anhedonia.

Abstract

Anhedonia refers to the inability of experiencing pleasure in positive life events. It has been conceptualized as a stable yet malleable characteristic and is associated with hypoactivity in the mesolimbic and mesocortical dopaminergic systems. Very recently, it has been posited as an etiologic factor associated with drug addiction onset, escalation, and relapse. Prevention programming could be developed to counteract the harmful impact of anhedonia, so as to minimize its impact on drug misuse. Remedial efforts are those that either (1) permit the individual to tolerate low levels of pleasure without resorting to drug misuse or other maladaptive behaviors that may unhealthily besot pleasure (for example, through normalization, structuring time, or meditation) or (2) counteract anhedonia by enhancing ones capability to experience pleasure (for example, behavioral activation, positive psychology, pharmacotherapy, or pursuit of positive addictions). School-based activities could be developed that can be completed by individuals, small workgroups, or the whole classroom. The concept of anhedonia is described in this chapter, and possible prevention strategies that might be utilized in schools as well as other contexts are discussed.
