Impulsivity and adolescent substance use: Rashly dismissed as "all-bad"?
Matthew J. Gullo and Sharon Dawe
Abstract
The initial use of illicit drugs and alcohol typically occurs during
adolescence.
Individual differences in impulsivity and related constructs are
consistently identified as key factors in the initiation and later
problematic use of substances.
Consequently, impulsivity is generally regarded as a negative trait; one
that conveys only risk.
However, what is often overlooked in addiction science is the positive
role facets of trait impulsivity can play in everyday life and adaptive
functioning.
The following review aims to summarize recent advances in the
psychobiology of impulsivity, including current perspectives on how it
can convey risk for substance misuse.
The review will also consider the importance of adolescence as a phase
of life characterized by substantial neurodevelopment and natural
increases in impulsivity.
Uniquely, the review aims to reframe thinking on adolescent impulsivity
to include the positive with the negative, and discuss how such thinking
can benefit efforts for early intervention and future research.
