Dysfunctional Eating In An Australian Community Sample: The Role Of Emotion Regulation, Impulsivity, And Reward And Punishment Sensitivity, Peta Stapleton, Melissa Whitehead

Peta B. Stapleton

This study aimed to examine the role of emotion regulation and reinforcement sensitivity in dysfunctional eating behaviours. Two hundred twenty-eight adults from the Australian community completed self-report inventories assessing the variables. Dysfunctional restrained eaters differed from those who did not engage in restrained eating in terms of their emotion regulation, impulsivity, and sensitivity to reward. Difficulties in emotion regulation, low impulsivity, and sensitivity to reward predicted engagement in restrained eating. Emotional eaters significantly differed from those who did not engage in dysfunctional levels of emotional eating in terms of their emotion regulation, impulsivity, and sensitivity towards reward, and difficulties in …

Rash Impulsiveness And Reward Sensitivity In Relation To Risky Drinking By University Students: Potential Roles Of Frontal Systems, Michael Lyvers, Helen Duff, Vanessa Basch, Mark Edwards

Mike Lyvers

Background: Two forms of impulsivity, rash impulsiveness and reward sensitivity, have been proposed to reflect aspects of frontal lobe functioning and promote substance use. The present study examined these two forms of impulsivity as well as frontal lobe symptoms in relation to risky drinking by university students. Methods: University undergraduates aged 18–26 years completed the Alcohol Use Disorders Identification Test (AUDIT), Barratt Impulsiveness Scale (BIS-11), Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), Frontal Systems Behavior Scale (FrSBe), and a demographics questionnaire assessing age, gender, and age of onset of weekly drinking (AOD). Results: AUDIT-defined harmful drinkers reported earlier …


Strengthening The Case Against Functionally Significant Serotonergic Neurotoxicity In Human Mdma (Ecstasy) Users, Michael Lyvers Oct 2012

Strengthening The Case Against Functionally Significant Serotonergic Neurotoxicity In Human Mdma (Ecstasy) Users, Michael Lyvers

Mike Lyvers

Extract:Halpern and colleagues [1] have overcome some of the methodological issues raised previously [2] concerning their initial pilot study of ecstasy users [3]. Their latest study [1] found that of 15 neuropsychological tests tapping various cognitive and memory functions reported previously by others to differentiate ecstasy users from controls, only the Revised Strategy Applications Test (RSAT) showed a clear indication of poorer performance in heavy (but not moderate) ecstasy users compared to controls, ecstasy users were selected for low exposure to other illicit drugs and alcohol, whereas in most other studies of this type the influence of potentially confounding associations …
