Determinants of Maintaining a Daily Yoga Practice: Health Locus of Control and Self-determination Theory Perspective.

Background: Despite the growing evidence of the health benefits of a yoga practice, little is known about the factors that contribute to its sustained practice.

Aims: The objectives of the present study were twofold: (1) to describe the personal characteristics (age, education level, and marital status) and yoga asana-related behavior of participants who practice Ashtanga and (2) to examine the health locus of control (HLOC) (an individual's beliefs about the extent of control that they have over things that happen to them) and self-determination theories. (People are able to become self-determined when their needs for competence, connection, and autonomy are fulfilled in relation to the motivated behavior.

Driving during alcohol hangover among dutch professional truck drivers.

Objectives: Alcohol hangover may impair potentially dangerous daily activities such as driving a car or operating heavy machinery. The purpose of the present study was to determine (1) whether driving during alcohol hangover is a problem of concern among professional Dutch truck drivers and (2) to what extent they think their hangover state affects driving performance.

Methods: Three hundred forty-three professional truck drivers were interviewed at a Dutch trucker festival.

Next day effects of naturalistic alcohol consumption on tasks of attention.

Objectives: The aim of this study was to examine the next day effects of alcohol consumption on a range of attention tasks.

Methods: The study followed a counterbalanced repeated measure design, with participants tested the morning following normal/usual alcohol consumption and again the morning after no alcohol consumption. Participants were 48 social drinkers (15 men and 33 women), who performed attention tests at 9 am, 11 am, or 1 pm.

Measurement of alcohol hangover severity: development of the Alcohol Hangover Severity Scale (AHSS).

Objective: This study aims to develop a new alcohol hangover symptom severity scale and compare its effectiveness with the Hangover Symptoms Scale (HSS), the Acute Hangover Scale (AHS), and a one-item hangover score.

Methods: Data from 1,410 Dutch students (Penning et al., Alcohol Alcohol 47:248-252, 2012) on the severity of 47 hangover symptoms were re-analyzed to develop the Alcohol Hangover Severity Scale (AHSS).

The role of craving in AUDs: dimensionality and Differential Functioning in the DSM-5.

Background: The dimensionality and the contribution of the proposed diagnostic criteria for the DSM-5 model of alcohol-use disorders (AUDs) which will provide guidelines for future diagnoses have not been examined in depth.

Method: Data from past year drinkers in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), Wave 2 (n=22 177) were analysed. Severity and discrimination of DSM-5 diagnostic criteria was determined using a two-parameter logistic Item Response Theory model.

Direct comparison of the cognitive effects of acute alcohol with the morning after a normal night's drinking.

Objective: The aim of this study was to compare performance measures after acute alcohol consumption (intoxication) with the performance the day after a normal night's drinking (hangover).

Methods: Eighty-four social drinkers took part in two studies that followed a counterbalanced repeated measure design. Fifteen men and 33 women were tested the morning (09:00, 11:00 or 13:00 h) following normal/usual alcohol consumption and the morning after no alcohol consumption; the order of testing was counterbalanced.

Alcohol hangover symptoms and their contribution to the overall hangover severity.

Aims: Scientific literature suggests a large number of symptoms that may be present the day after excessive alcohol consumption. The purpose of this study was to explore the presence and severity of hangover symptoms, and determine their interrelationship.

Methods: A survey was conducted among n = 1410 Dutch students examining their drinking behavior and latest alcohol hangover.

A review of the next day effects of alcohol on subjective mood ratings.

Alcohol-induced hangover is commonly experienced after excessive alcohol consumption. This paper presents a critical review of literature on the next day effects of excessive alcohol consumption on subjective ratings of mood. The review has identified 7 comprehensive studies which have followed either the pharmacological approach or the naturalistic approach to investigating the mood state of the individual during the post intoxication hangover phase.

The alcohol hangover research group consensus statement on best practice in alcohol hangover research.

Alcohol-induced hangover, defined by a series of symptoms, is the most commonly reported consequence of excessive alcohol consumption. Alcohol hangovers contribute to workplace absenteeism, impaired job performance, reduced productivity, poor academic achievement, and may compromise potentially dangerous daily activities such as driving a car or operating heavy machinery. These socioeconomic consequences and health risks of alcohol hangover are much higher when compared to various common diseases and other health risk factors.

Next-day effects of alcohol and an additional stressor on memory and psychomotor performance.

Objective: This study aimed to investigate the effects of a stressor, white noise, on cognitive performance of subjects in the compromised hangover state.

Method: The study followed a mixed factorial, counterbalanced, repeated-measures design with noise, order of testing, and time of testing as between-participants factors and state during testing as a within-participants factor. Seventy-eight participants performed memory and psychomotor tasks the morning after a regular night of drinking and the morning after a night of no alcohol consumption.

Alcohol hangover effects on measures of affect the morning after a normal night's drinking.

Aim: To investigate the effects of students' usual levels of alcohol consumption on aspects of mood and anxiety the following morning.

Methods: Students were recruited who consumed their usual quantity of any type of alcoholic beverage in their chosen company and then completed assessments of the effects the following day. The timing of drinking was restricted to the period between 22:00 and 02:00 h the night before testing as these are the most popular hours for consuming alcohol in the population under investigation.

Patterns of alcohol consumption in a Northern Irish sample.

This paper examines the drinking habits of a Northern Irish sample during a six-month period in 1998. In addition the study examines the influence of contextual variables on the quantity and frequency of alcohol consumption. Questionnaires were administered to 600 participants; the response rate was 39.

Next day effects of a normal night's drinking on memory and psychomotor performance.

Aim: To investigate in social drinkers the effects of a 'normal' evening of drinking alcohol on cognitive performance.

Methods: Aiming for ecological validity, the study required participants to consume their usual quantity of any type of alcoholic beverage in their chosen company (hangover situation). However, the timing of drinking was restricted to the period between 22:00 and 02:00 hours on the night before testing.
