| Additional information regarding sample selection. | Patients were recruited across three consultation and hospital centres: - CMME Alcohol Dependence Unit, Sainte Anne Hospital Centre (75014, Paris) - Corentin Celtin Hospital Centre Psychiatric Department (92139 Issy-les-Moulineaux), - Louis Mourier UHC Addiction Unit (92700 Colombes). A gift certificate for 30 Euro was paid to control subjects and related parties to facilitate recruitment. |
| Database objective | |
| Main objective |
The main objective is to investigate the endophenotypic nature of sweet-liking in alcohol-dependence and to verify that the preference for sweetness is more common in subjects that are first-degree relatives of alcohol-dependent subjects than in control subjects.
Secondary objectives include: studying specific clinical (precocity, severity), family (family history), temperamental (sensation seeking, impulsiveness) and cognitive traits (measurement of visual hedonic response, IGT decision-making tasks) in alcohol-dependent subjects that prefer the sweetest solutions; investigating the mechanisms involved in this endophenotypic connection and testing the following hypotheses: - Either the preference for the sweetest solutions is secondary to alcohol dependence; - Either the preference for sweetness is a marker of vulnerability to alcohol-dependence (sweetness preference would be a marker of an alcoholic sub-type associated with a higher genetic vulnerability that is close to Cloninger's clinical type 2 classification). |
| Inclusion criteria |
- Individuals aged between 18 and 65 years old;
- Alcohol-dependent* patients that have been weaned for at least a week (according to DSM-IV criteria); - Control subjects exposed to alcohol consumption but who do not fulfil dependence criteria*; - Individuals that are first-degree relatives of an alcohol-dependent person with no personal dependence criterion*. Exclusion criteria: - Individuals with an eating disorder, body mass index lower than 18 or greater than 30, or diabetes. |

| Details of collected clinical data | - The hedonic response to sweetness is measured using the Sweet Taste Test. Subjects are offered six sweet solutions of varying concentrations (between 0 and 0.84 M). The subjects were asked to evaluate the sugar concentration of each solution and the pleasure experienced using visual analogue scales. "Sweet Score" determination. The assessment is supplemented by several clinical and neurocognitive tests, including: - a computer-based, visual hedonic response test to rate the level of pleasure experienced with a series of standardised pictures of various pleasant landscapes; - The Barratt Impulsiveness Scale (BIS-11), a self-administered questionnaire that assesses impulsiveness according to three factors: motor impulsiveness, cognitive impulsiveness and planning difficulty; - Hospital Anxiety and Depression Scale (HAD), self-assessment questionnaire measuring anxiety and mood at the time of the assessment (Zigmond et al., 1983). |
