[A questionnaire of insight into schizophrenia--"my thoughts and feelings"].

AIM Construction of a brief, self-rating questionnaire of insight into schizophrenia, that can be useful in everyday practice. METHOD The questionnaire is based on reports of patients with good remissions, confronted with the group interviews with severely psychotic patients without insight. They led to the formulation of 16 questions with three possible answers reflecting lack of insight, full insight and partial insight. 6 items that have the most discriminating power of patients with and without insight were selected in the study of 367 patients assessed by psychiatrists acting as the competent judges. The reliability of this questionnaire is good--alfa Cronbach = 0.8. In the next study with 128 patients, a similar reliability was fund--alfa Cronbach = 0.77. The validity measured as the correlation with PANSS item "Lack of Judgment and Insight" was acceptable r = -0.55. RESULTS The 6-items questionnaire of insight into schizophrenia--"My thoughts and feelings" has good reliability and acceptable validity. The discussion of results with the patient, based on rules of cognitive behavioural therapy aiming at the shaping of insight was described as well as the preliminary sten norms were described. CONCLUSIONS The questionnaire may be useful in the screening of patients with low insight into schizophrenia as well for a psychoeducative discussion of its results.
