Mental health states and impulsivity: role of stress, depression, and anxiety

Existing literature has reported enormously on the interaction between depression and impulsivity, anxiety and impulsivity, stress and impulsive behaviors in different populations. Nevertheless, there are several inconclusive findings regarding how depression, anxiety, and stress independently relate to impulsivity. These inclusive findings could serve as fertile ground to inform the appropriateness of approaches and procedures applied in establishing connections between depression, anxiety, stress, and impulsivity. Further, it is important to note that studies examining the influence of stress on impulsivity have revealed mixed outcomes. Therefore in this chapter, we will review the literature on depression, anxiety, stress, and impulsivity separately. Aside from that, we will review related literature with a focus on individual psychological correlates such as depression, anxiety, and stress and how they interact with impulsivity. In addition, we will outline potential gaps in literature and offer potential directions for future research in these areas.
