Translation, Adaptation and Initial Validity Study of the Magical Ideation Scale
Keywords:
Psychological tests, Test adaptation, Semantic analysis, test validity, Magical thinkingAbstract
Magical Ideation Scale (MIS) is a self-report scale that assesses magical thinking, a phenomenon linked to
schizophrenia. This study aimed to adapt the MIS to Brazilian culture, as well as investigate its discriminative sensitivity based on a validity study. In the adaptation stage, 283 subjects completed MIS, marking words and misunderstood items. Subsequently, the scale was administered to 70 subjects divided into groups: Patients and Non-patients. A comparison of the performance of both groups was realized using Student’s t, which revealed significant differences, while Cohen’s d showed a strong discrepancy between the two groups. The Pearson correlation between the diagnosis of schizophrenia and MIS showed a positive association of significant magnitude. The results are interpreted as evidence of validity for the MIS.
