Design: Comparison of the sensitivity and specificity of on-site testing of samples of OF and urine collected on the same occasion, using subsequent blind laboratory analysis of the same urine samples as the standard.
The repeatability of measurement on the same occasion was evaluated by calculating the within-occasion coefficient of variation.
Binge drinking Men were asked how often during the last month they had consumed at least five standard glasses of alcohol on the same occasion, while women were asked how often they had consumed at least four standard glasses of alcohol on the same occasion [ 33].
Standard resting 12-lead ECG were recorded at a paper speed of 50 mm/s, on the same occasion as blood samples were drawn, physical examination performed and questionnaires completed.
Binge drinking was assessed by asking participants to report the frequency of drinking ≥5 alcoholic drinks on the same occasion in the past 6 months [ 58, 59].
Two-thirds of women (68.9%) reported gang rape (rape by more than one assailant on the same occasion) and 46% of women reported being abducted (forcibly taken from the place of the first rape encounter for more than one day) by their assailant.
Binge drinking is defined in the ASI as the drinking of at least five (men) or four (women) standard drinks on the same occasion, and a history of regular binge drinking reported here is defined as this drinking pattern occurring on at least three days a week.
Although the fact that the questionnaire was administered at the time of the final assessment test may have had an influence on the data, the questionnaire was administered on the same occasion for each of the two year-groups.
On the other hand, if a person eats fruits deliberately on the same occasion, the engagement of the person in this behavior may also reflect the results of preference and a deliberate choice for this behavior.
Because maternal depression and maternal cognitive style were measured on the same occasion, we cannot determine the direction of causality.
As CAGE was not included in the 2008 wave, we used a single question based on AUDIT to control for baseline heavy drinking: 'How often do you drink six such glasses [of alcohol] or more on the same occasion?' A 'glass' is equivalent to: 50 cl medium strength beer or 33 cl strong beer or 1 glass of wine or 1 small glass of fortified wine or 4 cl spirits, e.g. whisky.
