Aspects of personality of soldiers presenting to an endoscopy clinic.

Eysenck Personality Questionnaires were completed by a consecutive series of 60 soldiers attending a military endoscopy clinic. Each individual was pair-matched with a non-endoscoped soldier from a medical ward and a soldier from the hospital alcohol treatment unit. Alcohol dependence and related disabilities were measured using the MAST, CAGE and SADQ questionnaires and liver function tests and MCV estimates were performed. Alcohol questionnaire scores and laboratory tests were analysed by discriminant function analysis and by applying 'cut-off' scores of the questionnaires. Analyses of the personality dimensions were carried out by analyses of variance and were examined in relation to sample, alcohol questionnaire scores and endoscopic findings. The soldiers from the alcohol treatment unit had the highest neuroticism score, followed by the soldiers attending the endoscopy clinic. Of the endoscoped soldiers, those diagnosed as non-ulcer dyspeptics had higher neuroticism scores than soldiers with ulcers. This finding was not associated with increased prevalence of alcohol dependence and related disabilities.
