The current study investigates the role of psychological distress as a key factor in disrupting decision-making processes in the context of substance and behavioral addictions. A large community sample (N = 668) completed a gamified two-stage task to investigate the link between model-free (habitual) task behavior and a wide range of addictive behaviors. Addictive behaviors included substance use (alcohol, nicotine, and illicit drug use) and behavioral addictions (problematic use of the internet, addictive eating, shopping, and gambling). The relationship between habitual task behavior and addictive engagement was investigated using structural equation modelling with a bifactor latent variable structure, which was modeled and tested; one for substance use and one for behavioral addictions. For participants with higher levels of psychological distress, greater habitual task behavior was a significant predictor of behavioral addiction risk (<em>β</em> = −0.188, <em>SE</em> = 2.061, <em>p</em> = .016), specifically problematic use of the internet (<em>β</em> = −0.148, <em>SE</em> = 0.045, <em>p</em> = .018) and eating behaviors (<em>β</em> = −0.191, <em>SE</em> = 0.016, <em>p</em> &lt; .001). These findings support our proposition that psychological distress disrupts cognitive control, leading to a greater reliance on habitual decision-making and non-substance addictive behaviors.

In our preclinical study, we explored the behavioral effects of R- and S-ketamine at 10 mg/kg in clinically relevant treatment protocol using Wistar-Kyoto rats as a depression model and Wistar rats as a control. Undesirable psychomotor effects were evaluated with locomotor stimulation and sensitization, ataxia, and stereotypy.

After repeated treatment, sensitization to locomotor stimulating effects, and tolerance to ataxic effects of S-ketamine develops. We found no persistent changes due to ketamine treatments. Taken together, our results may indicate that depressed patients would be more prone to negative side effects of ketamine, compared to healthy controls. However, after repeated treatment, tolerance to side effects may develop and make the treatment more tolerable.
