Article Abstract
Introduction: Cue-induced cigarette cravings have been oft studied as potentially important predictors of smoking cessation outcomes. The literature on the relationship between cue-induced cravings and cessation, however, remains mixed. One possible explanation for the discrepant results in the literature may be the as-yet untested variability in expectancies of craving. Indeed, as with many interoceptive responses, cravings and their downstream consequences may be influenced by expectancies. To date, no study has examined the influence of expected cravings following smoking cue exposures on actual craving experiences and cessation outcomes. The objective of this study, therefore, was to test the possibility that smokers' expected craving levels in response to smoking cues would be related to actual cravings following cue exposure and that expected cravings would be related to cessation outcomes.
Methods: Nicotine-dependent adult smokers (n = 153) were exposed to sets of neutral and smoking cues and completed questionnaires assessing (a) prior to the exposures, the cigarette craving levels they expected to experience following the cue exposures and (b) following the exposures, their actual craving levels. Participants also reported the duration of their most recent quit attempt and their perceived future quit difficulty.
Results: Findings indicated that expected cravings assessed prior to the cue exposures were significantly related to actual cravings following the exposures. In addition, both expected cravings and actual cravings were related to shorter previous quit duration and higher perceived quit difficulty.
Conclusions: Study results highlight the importance of considering both expected and actual cravings in cue-induced craving paradigms.

Long-Term High-Intensity Interval Training Intervention Improves Emotional Conflict Control in Association With Right Ventrolateral Prefrontal Activation in Males With Methamphetamine Use Disorder: A Randomized Controlled Trial.

Acute high-intensity interval training (HIIT) has cognitive benefits in individuals with methamphetamine use disorder (MUD), yet it remains largely unknown the benefits of long-term HIIT on emotional conflict control and its neural mechanism in individuals with MUD. The current study conducted a 36-week low-volume HIIT intervention to investigate the effects of HIIT on emotional conflict control in males with MUD and their prefrontal cortex (PFC) activation. This study was a sub-study of the Study for Rehabilitation Training Model Construction and Training Effect of High Intensity Compound Exercise Prescription.

Background: Caregiver-involved treatments for adolescents with alcohol use disorder and co-occurring disorders (AUD+CODs) are associated with the best treatment outcomes. Understanding what caregiving practices during treatment improve core adolescent treatment targets may facilitate the refinement and scalability of caregiver-involved interventions. Caregiving is dynamic, varying by context, affect, and adolescent behavior.

BACKGROUNDStudies have demonstrated the role of ghrelin in alcohol-related behaviors and consumption. Blockade of the growth hormone secretagogue receptor (GHSR), which is the ghrelin receptor, has been shown to decrease alcohol drinking and reward-related behaviors across several animal models. We previously conducted a human study testing a GHSR inverse agonist/competitive antagonist, PF-5190457, in individuals who are heavy drinkers and showed its safety when coadministered with alcohol.

Introduction: Prior research suggests that the e-Cigarette Wisconsin Inventory of Smoking Dependence Motives (e-WISDM) distinguishes primary (e-PDM) and secondary dependence (e-SDM), however, there is little research on these e-WISDM dimensions and prior research comprised dual users (using cigarettes and e-cigarettes) and those using older generations of e-cigarettes.
Methods: Those exclusively using contemporary e-cigarettes (N = 164) completed the e-WISDM and a laboratory self-administration session and rated pre-use expectancies and post-use experiences.
Results: Only a 1-factor model limited to the primary scales (Automaticity, Tolerance, Craving, Loss of Control) achieved good model fit.
New therapeutic approaches for alcohol dependence (AD) include virtual reality (VR)-based treatments offering scalable options for cue exposure (CE), a well-established strategy in cognitive behavioral therapy. This study aimed to evaluate the feasibility and tolerability of a new VR-CE paradigm. On an explorative basis, factors influencing the induction of craving were examined.
