Personnalité schizotypique en milieu universitaire à Marrakech (Maroc)

Schizotypal personality disorder is considered as a trouble-generator spectrum of schizophrenia; patients with this disorder are at high risk of developing schizophrenia, particularly when not detected earlier. The average SPQ questionnaire score in our sample was 25.33 + 11.77. Very similar scores are found in other studies concerning student populations. According to the method of Raine threshold, scores have been defined by the values corresponding to 10-degree and 90-degree percentile distribution of collected scores. In our study, these lower and upper threshold scores were 10/74 and 44/74 which appear similar to those calculated by Raine (12/74 and 41/74), Dumas et al. (9/74 and 40/74), Dumas et al. (7/74 and 40/74), and in the study of Gaha et al. who found upper and lower threshold score of respectively 9/74 and 42/74. Several epidemiological studies conducted since the early 1990s indicate that the lifetime prevalence of drug consumption (abuse or dependence) is nearly 50 % in schizotypal personality before the outbreak of schizophrenic symptoms, schizotypal personalities tend to consume these substances to relieve their anhedonia, to socialize and to allay their anxiety, which explains the co-occurrence of schizophrenia and drug consumption.
