Theoretically, it is possible that TDV could lead in the long term to further violence, drug use, and negative mental and physical health, as well as that these negative factors could increase the risk of TDV, or that bidirectional relationships exist. 11 Various mechanisms have been discussed to explain the process through which TDV could be longitudinally associated with negative outcomes. Prospective studies on adolescents are therefore critical for strengthening the evidence base of the long-term risks of TDV. 10 Additionally, it is unclear whether TDV might have differential impacts depending on sex and the direction of violence (i.e., victimization/perpetration). This is particularly important for the longitudinal assessment of violent behaviors (reoccurrence of violence in romantic relationships) and health-related risks, such as suicidal attempts, drug abuse, and a wide range of adverse mental and physical outcomes. Although informative, evaluation of such correlates does not allow conclusions to be drawn on the direction and temporal relationships between TDV and adverse outcomes.
