Abstract
Rationale: Two prominent neurobiological models of addiction, the allostatic and incentive-sensitization models, have guided clinical research on alcohol use disorder (AUD). While these models are often viewed in isolation, it is plausible these theories are complimentary.
Objectives: Use naturalistic, daily diary reports to determine whether positive and negative mood states influence alcohol cue sensitivity in a clinical sample with AUD.
Methods: This is an exploratory analysis of daily diary data collected from a non-treatment seeking sample with current AUD over two weeks. Eligible adult participants (N = 50) were enrolled in a medication trial for AUD. Each morning, participants retrospectively reported on pre-drinking mood states, alcohol cue exposure, and craving levels, and subsequent alcohol intake occurring the previous day. Multilevel models tested the singular and interactive relationships between cue exposure and mood states with craving and drinking. Within-person and between-person outcomes were assessed. Exploratory analyses examined whether individuals with withdrawal-related dysphoria were more vulnerable to mood states and cue-reactivity.
Results: Greater cue exposure was associated with higher daily drinking levels (p = .001), but not daily alcohol craving. Higher negative mood (p < .0001) and lower positive mood (p = .012) were associated with higher daily alcohol craving, but not same-day drinking. As negative mood levels increased (p < .01) and positive mood levels decreased (p = .010), the relationship between cue exposure and same-day drinking became stronger. These findings were most pronounced among those with withdrawal-related dysphoria.
Conclusions: Findings provided concomitant support for the allostatic model and incentive-sensitization model as determinants of alcohol craving and drinking among individuals with AUD.

Official Journal of the European Behavioural Pharmacology Society (EBPS)
Psychopharmacology is an international journal that covers the broad topic of elucidating mechanisms by which drugs affect behavior. The scope of the journal encompasses the following fields:
Human Psychopharmacology: Experimental
This section includes manuscripts describing the effects of drugs on mood, behavior, cognition and physiology in humans. The journal encourages submissions that involve brain imaging, genetics, neuroendocrinology, and developmental topics. Usually manuscripts in this section describe studies conducted under controlled conditions, but occasionally descriptive or observational studies are also considered.
Human Psychopharmacology: Clinical and Translational
This section comprises studies addressing the broad intersection of drugs and psychiatric illness. This includes not only clinical trials and studies of drug usage and metabolism, drug surveillance, and pharmacoepidemiology, but also work utilizing the entire range of clinically relevant methodologies, including neuroimaging, pharmacogenetics, cognitive science, biomarkers, and others. Work directed toward the translation of preclinical to clinical knowledge is especially encouraged. The key feature of submissions to this section is that they involve a focus on clinical aspects.
Preclinical psychopharmacology: Behavioral and Neural
This section considers reports on the effects of compounds with defined chemical structures on any aspect of behavior, in particular when correlated with neurochemical effects, in species other than humans. Manuscripts containing neuroscientific techniques in combination with behavior are welcome. We encourage reports of studies that provide insight into the mechanisms of drug action, at the behavioral and molecular levels.
Preclinical Psychopharmacology: Translational
This section considers manuscripts that enhance the confidence in a central mechanism that could be of therapeutic value for psychiatric or neurological patients, using disease-relevant preclinical models and tests, or that report on preclinical manipulations and challenges that have the potential to be translated to the clinic. Studies aiming at the refinement of preclinical models based upon clinical findings (back-translation) will also be considered. The journal particularly encourages submissions that integrate measures of target tissue exposure, activity on the molecular target and/or modulation of the targeted biochemical pathways.
Preclinical Psychopharmacology: Molecular, Genetic and Epigenetic
This section focuses on the molecular and cellular actions of neuropharmacological agents / drugs, and the identification / validation of drug targets affecting the CNS in health and disease. We particularly encourage studies that provide insight into the mechanisms of drug action at the molecular level. Manuscripts containing evidence for genetic or epigenetic effects on neurochemistry or behavior are welcome.
