Endocrine responses and examination anxiety.
Endocrine and psychological function (measuring both affect and attitudes to study) were studied in 38 male medical students 4 weeks and 1-2 h before a major examination. Anxiety (or tension) and emotionality increased just before the examination, as did the 'denial' subscale of a 'coping' questionnaire. Serum cortisol and prolactin increased; serum testosterone and LH were unchanged. Both urinary noradrenaline and adrenaline were elevated. Increased cortisol correlated with increased prolactin across subjects; so, too, did levels of urinary noradrenaline and adrenaline, but the two sets of endocrine responses were not correlated with each other. Several of the trait scales predicted the endocrine response to the examination. The 'lie' scale of the Eysenck Personality Questionnaire correlated negatively with changes in both cortisol and prolactin, as did 'debilitating' anxiety, as defined by the Alpert-Haber scale. However, although there were no significant correlations between changes in hormone levels and those in any of the state scales, there was some relation between absolute hormone levels on the day of the examination. Measures of academic strategies or psychological responses to examinations do not predict the nature of the considerable hormonal response which occurs in this homogeneous set of high-achieving students.
