Alexithymia And Drinking In Young Adults: The Role Of Alcohol-Related Intrusive Thoughts, Michael Lyvers, Olena Lysychka, Fred Thorberg Aug 2015

Alexithymia And Drinking In Young Adults: The Role Of Alcohol-Related Intrusive Thoughts, Michael Lyvers, Olena Lysychka, Fred Thorberg

Mike Lyvers

Alexithymia refers to difficulties identifying and describing emotions, an externalised thinking style and a lack of imagination. Alexithymia has been linked to heavier drinking in community samples and is strongly associated with alcohol use disorders. Among patients undergoing treatment for alcohol dependence, alexithymia is associated with more intrusive thoughts about drinking. The present research asked whether this may also be the case in a non-clinical sample of social drinkers and whether such intrusive thoughts mediate the relationship between alexithymia and drinking. Participants were 113 university undergraduates aged 18–30 years who completed self-report indices of alexithymia (Toronto Alexithymia Scale-20, or TAS-20), …


Caffeine Use And Alexithymia In University Students, Michael Lyvers, Natalija Duric, Fred Thorberg Aug 2015

Caffeine Use And Alexithymia In University Students, Michael Lyvers, Natalija Duric, Fred Thorberg

Mike Lyvers

Alexithymia refers to difficulties with identifying, describing, and regulating one’s own emotions. This trait dimension has been linked to risky or harmful use of alcohol and illicit drugs; however, the most widely used psychoactive drug in the world, caffeine, has not been examined previously in relation to alexithymia. The present study assessed 106 male and female university students aged 18-30 years on their caffeine use in relation to several traits, including alexithymia. The 18 participants defined as alexithymic based on their Toronto Alexithymia Scale (TAS-20) scores reported consuming nearly twice as much caffeine per day as did non-alexithymic or borderline …


Trait Impulsivity Predicts D-Kefs Tower Test Performance In University Students, Michael Lyvers, Vanessa Basch, Helen Duff, Mark Edwards Jul 2015

Trait Impulsivity Predicts D-Kefs Tower Test Performance In University Students, Michael Lyvers, Vanessa Basch, Helen Duff, Mark Edwards

Mike Lyvers

The present study examined a widely used self-report index of trait impulsiveness in relation to performance on a well-known neuropsychological executive function test in 70 university undergraduate students (50 women, 20 men) aged 18 to 24 years old. Participants completed the Barratt Impulsiveness Scale (BIS-11) and the Frontal Systems Behavior Scale (FrSBe), after which they performed the Tower Test of the Delis-Kaplan Executive Function System. Hierarchical linear regression showed that after controlling for gender, current alcohol consumption, age at onset of weekly alcohol use, and FrSBe scores, BIS-11 significantly predicted Tower Test Achievement scores, b¼_.44, p


Blood Alcohol Concentration Is Negatively Associated With Gambling Money Won On The Iowa Gambling Task In Naturalistic Settings After Controlling For Trait Impulsivity And Alcohol Tolerance, Michael Lyvers, Nicole Mathieson, Mark Edwards Jun 2015

Blood Alcohol Concentration Is Negatively Associated With Gambling Money Won On The Iowa Gambling Task In Naturalistic Settings After Controlling For Trait Impulsivity And Alcohol Tolerance, Michael Lyvers, Nicole Mathieson, Mark Edwards

Mike Lyvers

Introduction: Acute alcohol intoxication has been found to increase perseverative errors on the Wisconsin Card Sorting Test, a well known neuropsychological index of prefrontal cortical functioning, in both laboratory and naturalistic settings. Method: The present study examined the relationship between levels of alcohol consumption at campus drinking venues and performance of the Iowa Gambling Task (IGT), another neuropsychological test designed to assess prefrontal cortex dysfunction, after controlling for potential confounding variables including habitual alcohol intake (as a proxy for alcohol tolerance), trait impulsivity, and everyday executive functioning. Results: The 49 participants of both genders aged 18 to 30 years were …


Cognitive Trait Anxiety, Situational Stress, And Mental Effort Predict Shifting Efficiency: Implications For Attentional Control Theory, Elizabeth Edwards, Mark Edwards, Michael Lyvers Feb 2015

Cognitive Trait Anxiety, Situational Stress, And Mental Effort Predict Shifting Efficiency: Implications For Attentional Control Theory, Elizabeth Edwards, Mark Edwards, Michael Lyvers

Mike Lyvers

Attentional control theory (ACT) predicts that trait anxiety and situational stress interact to impair performance on tasks that involve attentional shifting. The theory suggests that anxious individuals recruit additional effort to prevent shortfalls in performance effectiveness (accuracy), with deficits becoming evident in processing efficiency (the relationship between accuracy and time taken to perform the task). These assumptions, however, have not been systematically tested. The relationship between cognitive trait anxiety, situational stress, and mental effort in a shifting task (Wisconsin Card Sorting Task) was investigated in 90 participants. Cognitive trait anxiety was operationalized using questionnaire scores, situational stress was manipulated through …


Mood, Mood Regulation, And Frontal Systems Functioning In Current Smokers, Long-Term Abstinent Ex-Smokers, And Never-Smokers, Michael Lyvers, Cassandra Carlopio, Vicole Bothma, Mark Edwards Jul 2014

Mood, Mood Regulation, And Frontal Systems Functioning In Current Smokers, Long-Term Abstinent Ex-Smokers, And Never-Smokers, Michael Lyvers, Cassandra Carlopio, Vicole Bothma, Mark Edwards

Mike Lyvers

Indices of mood, mood regulation, and executive functioning were examined in 61 current smokers who have smoked daily for at least one year, 36 ex-smokers who had not smoked a cigarette for at least one year, and 86 never-smokers. All participants completed the following measures online: Depression Anxiety Stress Scales (DASS-21), the Negative Mood Regulation (NMR) scale, the Frontal Systems Behavior Scale (FrSBe), the Fagerström Test for Cigarette Dependence (FTCD), and the Alcohol Use Disorders Identification Test (AUDIT). Multivariate analysis of variance (MANOVA) followed by Tukey post-hoc tests revealed significant differences (p


Impulsivity, Executive Cognition And Reward Sensitivity In Relation To Excessive Or Problematic Alcohol Consumption, Michael Lyvers, Mark Edwards Jul 2014

Impulsivity, Executive Cognition And Reward Sensitivity In Relation To Excessive Or Problematic Alcohol Consumption, Michael Lyvers, Mark Edwards

Mike Lyvers

Background: Deficits of frontal lobe functioning and associated cognitive impairments are well known correlates of chronic alcoholism and are commonly interpreted as reflecting cumulative effects of high alcohol exposure (Lyvers, 2000). Alternatively, such associations may reflect traits predating alcohol exposure which predispose to risky drinking . For example, university students have a higher prevalence of alcohol use as well as risky drinking than do non-students of the same age, yet not all students drink at risky levels, suggesting that excessive alcohol use by young adults may be influenced by underlying trait factors in addition to social factors. Recent studies using …


Alexithymia And Alcohol: The Roles Of Punishment Sensitivity And Drinking Motives, Michael Lyvers, Penelope Hasking, Bonnie Albrecht, Fred Thorberg Jul 2014

Alexithymia And Alcohol: The Roles Of Punishment Sensitivity And Drinking Motives, Michael Lyvers, Penelope Hasking, Bonnie Albrecht, Fred Thorberg

Mike Lyvers

Alexithymia refers to difficulties identifying and describing feelings. It is suspected of being a risk factor for problematic drinking, an idea examined by this study. In 178 women and 84 men alexithymia was associated with male gender, coping motives for drinking and sensitivity to punishment. Individuals with alexithymia reported stronger coping motives and sensitivity to punishment compared to those with borderline or no alexithymia. Path analysis indicated that the relationship between the alexithymia dimension difficulties identifying feelings and coping motives was mediated by sensitivity to punishment, and the relationship between sensitivity to punishment and risky drinking was mediated by coping …


Illicit Use Of Lsd Or Psilocybin, But Not Mdma Or Nonpsychedelic Drugs, Is Associated With Mystical Experiences In A Dose-Dependent Manner, Michael Lyvers, Molly Meester Jul 2014

Illicit Use Of Lsd Or Psilocybin, But Not Mdma Or Nonpsychedelic Drugs, Is Associated With Mystical Experiences In A Dose-Dependent Manner, Michael Lyvers, Molly Meester

Mike Lyvers

Psychedelic drugs have long been known to be capable of inducing mystical or transcendental experiences. However, given the common “recreational” nature of much present-day psychedelic use, with typical doses tending to be lower than those commonly taken in the 1960s, the extent to which illicit use of psychedelics today is associated with mystical experiences is not known. Furthermore the mild psychedelic MDMA (“Ecstasy”) is more popular today than “full” psychedelics such as LSD or psilocybin, and the contribution of illicit MDMA use to mystical experiences is not known. The present study recruited 337 adults from the website and newsletter of …


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 Jul 2014

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 …


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 …

Alexithymia In Alcohol Dependent Patients Is Partially Mediated By Alcohol Expectancy, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Cameron Hurst, Jason Connor, Gerald Feeney Sep 2011

Alexithymia In Alcohol Dependent Patients Is Partially Mediated By Alcohol Expectancy, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Cameron Hurst, Jason Connor, Gerald Feeney

Mike Lyvers

Background: Up to fifty percent of alcohol dependent individuals have alexithymia, a personality trait characterised by difficulties identifying and describing feelings, a lack of imagination and an externalised cognitive style. Although studies have examined alexithymia in relation to alcohol dependence, no research exists on mechanisms underlying this relationship. The present study examined the mediational effect of alcohol expectancies on alexithymia and alcohol dependence.Methods: 230 outpatients completed the Toronto Alexithymia Scale (TAS-20), the Drinking Expectancy Questionnaire (DEQ) and the Alcohol Use Disorder Identification Test (AUDIT).Results: Regression analysis showed that alexithymia and alcohol dependence was, in two of three cases, partially mediated …


Negative Mood Regulation Expectancies, Frontal Lobe Related Behaviors And Alcohol Use, Michael Lyvers, Fred Arne Thorberg, Adrienne Ellul, Jan Turner, Mark Bahr Sep 2011

Negative Mood Regulation Expectancies, Frontal Lobe Related Behaviors And Alcohol Use, Michael Lyvers, Fred Arne Thorberg, Adrienne Ellul, Jan Turner, Mark Bahr

Mike Lyvers

Negative mood regulation (NMR) expectancies have been linked to substance problems in previous research, but the neurobiological correlates of NMR are unknown. In the present study, NMR was examined in relation to self-report indices of frontal lobe functioning, mood and alcohol use in 166 volunteers of both genders who ranged in age from 17 to 43 years. Contrary to expectations based on previous findings in addicts and problem drinkers, scores on the NMR scale did not differ between Low Risk and High Risk drinkers as defined by the Alcohol Use Disorders Identification Test (AUDIT). However, NMR scores were significantly negatively …


A Psychometric Comparison Of The Toronto Alexithymia Scale (Tas-20) And The Observer Alexithymia Scale (Oas) In An Alcohol-Dependent Sample, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Jason Connor, Gerald Feeney Sep 2011

A Psychometric Comparison Of The Toronto Alexithymia Scale (Tas-20) And The Observer Alexithymia Scale (Oas) In An Alcohol-Dependent Sample, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Jason Connor, Gerald Feeney

Mike Lyvers

Alexithymia is characterised by deficits in emotional insight and self-reflection that impact on the efficacy of psychological treatments. Given the high prevalence of alexithymia in Alcohol Use Disorders, valid assessment tools are critical. The majority of research on the relationship between alexithymia and alcohol-dependence has employed the self-administered Toronto Alexithymia Scale (TAS-20), The Observer Alexithymia Scale (OAS) has also been recommended. The aim of the present study was to assess the validity and reliability of the OAS and the TAS-20 in an alcohol-dependent sample. Two hundred and ten alcohol-dependent participants in an outpatient Cognitive Behavioral Treatment program were administered the …


Drinking Motives, Drinking Restraint And Drinking Behaviour Among Young Adults, Michael Lyvers, Penelope Hasking, Riana Hani, Madolyn Rhodes, Emily Trew Sep 2011

Drinking Motives, Drinking Restraint And Drinking Behaviour Among Young Adults, Michael Lyvers, Penelope Hasking, Riana Hani, Madolyn Rhodes, Emily Trew

Mike Lyvers

Motives to drink alcohol are widely thought to be the proximal cognitive factors involved in the decision to consume alcohol beverages. However it has also been argued that the ability to restrain drinking may be a more proximal predictor of drinking behaviour. The current study aimed to examine the relationships between drinking motives, drinking restraint and both alcohol consumption and alcohol-related problems in a sample of young adults. A sample of 221 young adults (aged 17–34 years) completed self-report measures assessing drinking behaviour, motives for drinking and drinking restraint. Multiple regression analyses revealed that coping, enhancement and social motives were …


Alexithymia, Craving And Attachment In A Heavy Drinking Population, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Jason Connor, Gerald Feeney Feb 2011

Alexithymia, Craving And Attachment In A Heavy Drinking Population, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Jason Connor, Gerald Feeney

Mike Lyvers

Up to fifty per cent of individuals with Alcohol use disorders (AUD) also have alexithymia a personality construct hypothesized to be related to attachment difficulties. The relationship between alexithymia, craving, anxious attachment and alcohol-dependence severitywas examined in254 patients participating in a Cognitive-Behavioral Therapy (CBT) programfor alcohol-dependence. Participants completed the Toronto Alexithymia Scale (TAS-20), the Obsessive Compulsive Drinking Scale (OCDS), the Revised Adult Attachment Anxiety Subscale (RAAS-Anxiety) and the Alcohol Use Disorder Identification Test (AUDIT). MANOVA indicated that individuals with alexithymia reported significantly higher levels of totalOCDS, obsessive thoughts about alcohol, and compulsive drinking urges and behavior, compared to the non-alexithymic …


Effects Of Acute Alcohol Consumption On Executive Cognitive Functioning In Naturalistic Settings, Michael Lyvers, Juliette Tobias-Webb Sep 2010

Effects Of Acute Alcohol Consumption On Executive Cognitive Functioning In Naturalistic Settings, Michael Lyvers, Juliette Tobias-Webb

Mike Lyvers

Laboratory studies have demonstrated that acute alcohol intoxication can disrupt performance on neuropsychological tests of executive cognitive functioning such as the Wisconsin Card Sorting Test (WCST). However, the generalizability of such findings to typical self-regulated alcohol intake in social settings can be questioned. In the present study, 86 young adults were recruited at Australian bars to perform a computer version of the WCST. Participants displayed blood alcohol concentrations (BACs) across a range from 0 to 0.15%. Although self-report measures of typical alcohol consumption, impulsivity, and frontal lobe related everyday functioning were all intercorrelated in line with other recent findings, multiple …


A Confirmatory Factor Analysis Of The Toronto Alexithymia Scale (Tas-20) In An Alcohol-Dependent Sample, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Cameron Hurst, Jason Connor, Gerald Feeney Sep 2010

A Confirmatory Factor Analysis Of The Toronto Alexithymia Scale (Tas-20) In An Alcohol-Dependent Sample, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers, Cameron Hurst, Jason Connor, Gerald Feeney

Mike Lyvers

Objective: To explore the factorial validity of the Toronto Alexithymia Scale (TAS-20) in an alcohol dependent population. Methods: Confirmatory factor analyses were conducted using structural equation modelling to evaluate the stability of the factor structure of the TAS-20. Based on previously reported factor structures, 1-factor, 2-factor and 3-factor models were examined, using maximum likelihood estimation. Results: Four of the five fit indices considered indicated a superior fit for the 3-factor model compared to the 2-factor and 1-factor models. Conclusion: This study demonstrates that the original 3-factor model of the TAS-20 was a more plausible fit to the data compared to …


Disinhibition And Reward Sensitivity In Relation To Alcohol Consumption By University Undergraduates, Michael Lyvers, Cameron Czerczyk, Anna Follent, Phoebe Lodge Aug 2010

Disinhibition And Reward Sensitivity In Relation To Alcohol Consumption By University Undergraduates, Michael Lyvers, Cameron Czerczyk, Anna Follent, Phoebe Lodge

Mike Lyvers

Deficits of prefrontal cortex functioning and associated executive cognitive impairments are well-known correlates of chronic alcoholism and may reflect cumulative effects of high alcohol exposure. However, such associations may also reflect traits predating alcohol exposure which predispose to heavy drinking. In the present investigation, 60 university undergraduates aged 18-25 years were administered the Alcohol Use Disorders Identification Test (AUDIT), Frontal Systems Behavior Scale (FrSBe), and Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ). All participants reported they were at least occasional drinkers who rarely or never used illicit drugs and had no reported history of head injury or neurological …


Alexithymia And Alcohol Use Disorders: A Critical Review, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers Aug 2010

Alexithymia And Alcohol Use Disorders: A Critical Review, Fred Thorberg, Ross Young, Karen Sullivan, Michael Lyvers

Mike Lyvers

All human beings experience emotion. However a number of individuals have difficulties recognising, processing and regulating their emotions. This set of emotional “deficits’ is classified as alexithymia. The prevalence rate of alexithymia in alcohol use disorders is between 45 and 67%. The objective of this paper is to review the published research on alexithymia and alcohol use, assess the methodological quality of this evidence, and draw the findings together to present a critical update on the relationship between alexithymia and alcohol use disorders. Yet, few research studies have comprehensively investigated alexithymia in alcohol use disorders, and a number of key …


Attachment In Relation To Affect Regulation And Interpersonal Functioning Among Substance Use Disorder Inpatients, Fred Arne Thorberg, Michael Lyvers Dec 2009

Attachment In Relation To Affect Regulation And Interpersonal Functioning Among Substance Use Disorder Inpatients, Fred Arne Thorberg, Michael Lyvers

Mike Lyvers

Attachment theory has been conceptualised as an affect regulation theory, proposing that attachment is associated with the expression and recognition of emotions as well as interpersonal functioning. Previous research has reported affect regulation difficulties in substance use disorders and addiction has been considered an attachment disorder. However, scarce empirical research exists on the relationship of attachment in relation to affect regulation and interpersonal functioning in those with substance use problems. Thus, the objective of the present study was to investigate potential associations between attachment, negative mood regulation (NMR) expectancies, fear of intimacy and self-differentiation in substance abusers. The revised adult …


Smoking And Psychological Health In Relation To Country Of Origin, Michael Lyvers, Tessa Hall, Mark Bahr Oct 2009

Smoking And Psychological Health In Relation To Country Of Origin, Michael Lyvers, Tessa Hall, Mark Bahr

Mike Lyvers

In English-speaking, Western-Anglo countries, where smoking has become stigmatized in recent decades as a result of widespread anti-smoking campaigns, smokers commonly report poorer psychological health on average than non-smokers do. This may be indirectly related to the strong pressures to quit in such countries, as poorer psychological health is associated with a reduced likelihood of quitting, thus leading to a selection bias for smokers with relatively poorer psychological health. In the present study, 147 smoker and non-smoker participants either came from Western-Anglo countries where smoking has become stigmatized (Australia, Canada, U.S.) or countries in regions where smoking remains relatively more …


Beer Goggles: Blood Alcohol Concentration In Relation To Attractiveness Ratings For Unfamiliar Opposite Sex Faces In Naturalistic Settings, Michael Lyvers, E. Cholakians, M. Puorro, S. Sundram Mar 2009

Beer Goggles: Blood Alcohol Concentration In Relation To Attractiveness Ratings For Unfamiliar Opposite Sex Faces In Naturalistic Settings, Michael Lyvers, E. Cholakians, M. Puorro, S. Sundram

Mike Lyvers

The popular notion that alcohol intoxication enhances perceptions of the physical attractiveness of the opposite sex has been inconsistently supported. The current study tested intoxicated and non-intoxicated persons of both genders in naturalistic settings after measuring their blood alcohol concentration (BAC) by a breath test. A sample of 80 heterosexual university student social drinkers was recruited at a campus pub and campus parties over a 3-month period to take a survey rating the attractiveness of unfamiliar faces of the opposite gender presented in photographs. Attractiveness ratings were positively correlated with BAC. Analysis of covariance (ANCOVA) was conducted on attractiveness ratings …
