آیا ما می توانیم به خودسنجی از رانندگی اعتماد کنیم؟ اثرات مدیریت تأثیر در پاسخ پرسشنامه رفتار راننده

Driver behaviour is often studied by using self-reports and questionnaires. Despite their obvious advantages, questionnaires are vulnerable to socially desirable response tendencies. In this study, the effects of socially desirable responding on self-reports of driving were studied by recording self-reports of driving in both public and private settings. In public settings, 47 applicants for a driving instructor training course completed the driver behaviour questionnaire (DBQ) and balanced inventory for socially desirable responding as a part of the entrance examination. In a private setting, 54 students of that training course completed the same questionnaires anonymously in the classroom. ANOVA results showed a difference between the two settings in six DBQ item scores, such that aberrant behaviours were reported less frequently in public than in private settings. The results indicated that bias caused by socially desirable responding is relatively small in DBQ responses.
