A Test of the Self-Medication Hypothesis Using a Latent Measurement Model: Are Stress and Impaired Control over Alcohol Mediating Mechanisms of Parenting Styles on Heavy Episodic Drinking and Alcohol-Related Problems among University Students?

Introduction: The self-medication hypothesis (SMH) suggests that individuals consume alcohol to alleviate stressful emotions. Still, the underlying mechanisms between stress and heavy episodic drinking remain to be explored. Impaired control over drinking (IC) reflects a failure of self-regulation specific to the drinking context, with individuals exceeding self-prescribed limits.

Does insomnia mediate the link between childhood trauma and impaired control over drinking, alcohol use, and related problems?

Introduction: Hyperarousal theory states that stressful negative events can result in a physiological response in the body leading to poor sleep quality. Childhood trauma is associated with many negative health consequences persisting into adulthood such as insomnia. Insomnia itself is a driver of poor physical and psychological health including excessive alcohol use.
