Data for Diagnostic validity of behavioural and psychometric impulsivity measures : an assessment in adolescent and adult populations Krishane Patel (15332633) Kulendran Myutan (24942985) Ara Darzi (31515) Ivo Vlaev (707044) Impulsive personality Obesity Behaviorism (Psychology) Obesity -- Psychological aspects Psychometrics Migrated from ePrints This investigation examined how different psychological and behavioural measures can be used to identify impulsive individuals. Five clinical groups split, between adolescents and adults, with varying levels of weight-management issues, were used to validate the impulsivity measures. The measures consisted of two behavioural, an inhibitory control measure (Stop Signal Task) and a Temporal Discounting measure, along with two personality measures, the Temperament and Character Inventory (Cloninger, Przybeck, Svrakic, & Wetzel, 1994) and the adolescent version (The Junior Temperament and Character Inventory) and finally the Barrat Impulsivity Scale (Patton, Stanford, & Barratt, 1995). The most sensitive was the Stop Signal Reaction time, which depicted significant differences in inhibitory control for all but two groups (Adult Lifestyle and Adult Healthy). The psychometric scales were able to sufficiently discriminate between obese and impulsive individuals with healthier participants. The Self-Control and Novelty Seeking subscales on the BIS. The Novelty Seeking subscale of the TCI-R and the JTCI, significantly discriminated between obese and healthy individuals. There was a high degree of association amongst the measures used, identifying that these measures can be used to monitor and measure impulsiveness in obese individuals for use in weight-loss interventions.<br><br>Data record consists of a data file in .csv format, additional documentation describing the experiments undertaken, and a readme file for the data. The sample collected was split across five groups, initially across age (adolescent and adult participants), then divided again into varying degrees of weight. Adolescents comprised of an obese sample and a healthy sample matched by age and sex were recruited from a local secondary school, whilst the adult sample was divided into an obese bariatric sample, obese individuals who required lifestyle management as a weight-reduction interventions, and healthy weight adults. Adults were not matched for age, gender or educational level. 2017-12-05T00:00:00Z Dataset Dataset 10.82444/warw.33802924.v1 https://figshare.com/articles/dataset/Data_for_Diagnostic_validity_of_behavioural_and_psychometric_impulsivity_measures_an_assessment_in_adolescent_and_adult_populations/33802924 CC BY 4.0
