Understanding Loss of Control Eating Through the Lens of Expectancies and Reinforcement Sensitization.

Objective: Prior research has indicated that outcome expectancies, sensitivity to punishment, and sensitivity to reward may predict harmful health behaviors concurrently, including disordered eating. Loss-of-control eating (LOCE), feeling unable to resist eating or stop once one has started, is associated with expectancies that eating alleviates negative affect (NA reduction expectancies) and expectancies that eating is rewarding (reward expectancies).

Method: A survey battery was administered examining LOCE pathology, sensitivity to punishment, sensitivity to reward, and eating expectancies to a sample of 1660 adults in the United States ( = 39.

Effects of medical cannabis use on physical and psychiatric symptoms across the day among older adults.

Introduction: Older adults are increasingly using medical cannabis (MC). It is unclear if therapeutic effects increase problematic use patterns. The current study addresses this issue by examining symptom trajectories across the day and using trajectories to predict problematic use.

A Deviance Regulation Theory Intervention Affects the Association Between Narcissistic Traits and Alcohol Harm Reduction Strategies in College Students.

College students continue to report problematic alcohol use. To mitigate adverse outcomes, recent studies have employed harm reduction strategies known as Protective Behavioral Strategies (PBS). Deviance Regulation Theory (DRT), an impression management intervention, has been used to promote the use of PBS.

The role of sociocultural factors on alcohol self-efficacy and protective drinking behaviors among Hispanic/Latinx young adults.

Objectives: Hispanic/Latinx drinkers have been found to experience more adverse alcohol-related consequences than any other racial/ethnic group. Due to this, researchers have looked at the connection between drinking and cultural factors, alongside discrimination, to further analyze what sociocultural factors lead to negative outcomes when drinking.

Design: Researchers used a sample of Hispanic/Latinx young adult drinkers (= 710) with an average age of 22.

Support for incentive-sensitization theory in adolescent ad libitum smokers using ecological momentary assessment.

The incentive-sensitization theory (IST) has emerged as a potentially useful theory in explaining substance addiction. IST postulates that the prolonged use of a substance can alter neural systems that are often involved in incentive motivation and reward processes, leading to an increased "sensitization" to the substance and associated stimuli. However, this increased sensitization is thought to mediate only the individual's craving of the substance (e.

Stress exposure and psychopathology alter methylation of the serotonin receptor 2A (HTR2A) gene in preschoolers.

Serotonin signaling pathways play a key role in brain development, stress reactivity, and mental health. Epigenetic alterations in the serotonin system may underlie the effect of early life stress on psychopathology. The current study examined methylation of the serotonin receptor 2A (HTR2A) gene in a sample of 228 children including 119 with child welfare documentation of moderate to severe maltreatment within the last 6 months.
