This Notice invites innovative research to characterize the consequences of psychosocial factors on mechanisms of action and determinants of vulnerability and/or resilience to substance use disorder (SUD). Research using basic or clinical approaches is appropriate.

Background

Psychosocial stress or stress induced by situations of social threat or inequity (e.g., low socioeconomic status, childhood trauma) has repeatedly been linked to substance use disorders (SUDs). Neighborhood poverty and social support are shown to influence substance use patterns. Among smokers, multiple psychosocial stressors are associated with relapse, and acute psychosocial stress has been demonstrated to enhance cigarette craving and smoking behavior. Similarly, psychosocial stress has been associated with greater risk of relapse in individuals with alcohol and cocaine use disorders.

Recent findings suggest that neurocognitive substrates pertinent to SUD are not only influenced by chronic psychosocial stress, particularly early life adversity, but also by acute stressors. Further, factors such as social support are seen to positively influence outcomes at various points in the substance use trajectory. However, the underlying mechanisms of these and other psychosocial factors, especially in the context of SUD, remain poorly understood. Taken together, the extant literature suggests that mechanistic investigations of SUDs need to be conceptualized with consideration to the underlying psychosocial factors. The goal of this Notice of Special Interest (NOSI) is to promote research directed at elucidating the neurobiological mechanisms by which psychosocial factors during different windows of development shape the trajectory of substance use and substance use disorder.

Research Objectives

NIDA seeks applications that support mechanistic research on psychosocial factors related to the substance use trajectory.

Research questions include but are not limited to:

• What are the genetic factors that determine individual differences in the propensity to develop SUDs after exposure to psychosocial stress?
• What is the interplay among genetic, epigenetic and psychosocial factors that contribute to substance use vulnerability and resilience?
• How do psychosocial factors alter neural network activity in circuits related to decision-making and compulsive behavior?
• What are the neurobiological mechanisms underlying moderators between psychosocial stress and risk for SUDs (e.g. coping strategies, personality traits)?
• What are the specific developmental windows during which psychosocial factors increase vulnerability to substance use?
• How does early life or repeated exposure to psychological trauma alter neural plasticity to increase risk for SUD?
• Are there sex differences in the influence of psychosocial factors on substance use and are these dependent or independent of sex hormones? What are the associated underlying neurobiological mechanisms of action?
