Alcohol Intoxication And Self-Reported Risky Sexual Behaviour Intentions With Highly Attractive Strangers In Naturalistic Settings, Michael Lyvers, Emma Cholakians, Megan Puorro, Shanti Sundram Oct 2012

Alcohol Intoxication And Self-Reported Risky Sexual Behaviour Intentions With Highly Attractive Strangers In Naturalistic Settings, Michael Lyvers, Emma Cholakians, Megan Puorro, Shanti Sundram

Mike Lyvers

Objective: The present investigation examined the relationship between alcohol intoxication and risky sex intentions in naturalistic settings.

Methods: Heterosexual young adults (n = 72) were approached at a campus pub and at campus parties. Blood alcohol concentration (BAC) was measured by a breath test and ranged from 0 to 0.18%. Participants rated their likely intent to have sex with 10 highly attractive unfamiliar models of the opposite gender, as depicted in photographs, if the opportunity arose. Photos varied in terms of accompanying information regarding risk, with three levels: slight risk, moderate risk and high risk.

Results: BAC …

Parental Bonding And Alexithymia: A Meta-Analysis, F. Thorberg, R. Young, K. Sullivan, Michael Lyvers Oct 2012

Parental Bonding And Alexithymia: A Meta-Analysis, F. Thorberg, R. Young, K. Sullivan, Michael Lyvers

Mike Lyvers

The primary purpose of this meta-analysis was to explore, clarify and report the strength of the relationship between alexithymia, as measured by the Toronto Alexithymia Scale (TAS-20), and parenting style as measured by the Parental Bonding Instrument (PBI).

Methods - Web of Science, PsycInfo, PubMed and ProQuest: Dissertations and Theses searches were undertaken, yielding nine samples with sufficient data to be included in the meta-analysis.

Results - Evidence indicated moderate to strong relationships between maternal care and alexithymia, and between maternal care and two of the three TAS-20 alexithymia facets (Difficulties Describing Feelings and Difficulties Identifying Feelings, but not Externally …

The Relationship Between Coping Strategies, Alcohol Expectancies, Drinking Motives And Drinking Behaviour, Penelope Hasking, Michael Lyvers, Cassandra Carlopio Oct 2012

The Relationship Between Coping Strategies, Alcohol Expectancies, Drinking Motives And Drinking Behaviour, Penelope Hasking, Michael Lyvers, Cassandra Carlopio

Mike Lyvers

Numerous models have been proposed in an attempt to explain both alcohol use and alcohol abuse. Many of these models propose that drinking behaviour is the result of a complex interplay of cognitive and behavioural variables including coping strategies, alcohol expectancies and motives for drinking. However few studies have explored how these elements may work together to predict drinking. The current study proposed a mediational model of alcohol use in which coping strategies are related to alcohol expectancies, which in turn are related to drinking motives. Drinking motives were then viewed as proximal predictors of drinking behaviour. There were 454 …

Risky Alcohol Use And Age At Onset Of Regular Alcohol Consumption In Relation To Frontal Lobe Indices, Reward Sensitivity And Rash Impulsiveness, Michael Lyvers, Helen Duff, Penelope Hasking Oct 2012

Risky Alcohol Use And Age At Onset Of Regular Alcohol Consumption In Relation To Frontal Lobe Indices, Reward Sensitivity And Rash Impulsiveness, Michael Lyvers, Helen Duff, Penelope Hasking

Mike Lyvers

Excessive alcohol consumption has been linked to predisposing traits that may reflect frontal lobe functioning, an idea explored by this study. The study recruited 132 adults of both genders aged 18-68 years who completed an online questionnaire battery. Sensitivity to punishment was the primary variable associated with age of onset for weekly drinking. The relationship between disinhibition and drinking behavior, as assessed by the AUDIT, was partially mediated by sensitivity to reward. The findings of this study suggest that several interrelated and heritable personality and neurobehavioral traits may promote earlier as well as riskier alcohol consumption.

Attachment Security And Alexithymia In A Heavy Drinking Sample, F.A. Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Cameron Hurst, J. Connor, G. Feeney Oct 2012

Attachment Security And Alexithymia In A Heavy Drinking Sample, F.A. Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Cameron Hurst, J. Connor, G. Feeney

Mike Lyvers

Attachment difficulties have been proposed as a key risk factor for the development of alexithymia, a multifaceted personality trait characterised by difficulties identifying and describing feelings, a lack of imagination and an externally oriented thinking style. This study investigated the relationship between attachment and alexithymia in an alcohol dependent population. Participants were 210 outpatients in a Cognitive Behavioural Treatment programme assessed on the Toronto Alexithymia Scale and the Revised Adult Attachment Scale. Significant relationships between anxious attachment and alexithymia factors were confirmed. Furthermore, alexithymic alcoholics reported significantly higher levels of anxious attachment and significantly lower levels of closeness (secure attachment) …

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 …

Alexithymia In Relation To Parental Alcoholism, Everyday Frontal Lobe Functioning And Alcohol Consumption In A Non-Clinical Sample, Michael Lyvers, Roy Onuoha, Fred Thorberg, Christina Samios May 2012

Alexithymia In Relation To Parental Alcoholism, Everyday Frontal Lobe Functioning And Alcohol Consumption In A Non-Clinical Sample, Michael Lyvers, Roy Onuoha, Fred Thorberg, Christina Samios

Mike Lyvers

Background: Recent studies have indicated that 45–67% of those in treatment for alcohol use disorders suffer from alexithymia, a multifaceted personality trait characterized by difficulties identifying and describing emotions and an externally oriented cognitive style. The high reported prevalence rates of alexithymia among those with alcohol dependence led to speculation that alexithymia is a personality dimension that may predispose to risky or problematic alcohol use.Methods: This notion was examined in 314 adult volunteers (54% female) aged 18–45 years (M=27.6 years), all of whom reported at least occasional alcohol consumption,who completed online surveys assessing alexithymia (Toronto Alexithymia Scale, or TAS-20), parental …
