Development and validation of the multi-dimensional questionnaire of scientifically unsubstantiated beliefs

Objective: There are several existing questionnaires measuring paranormal or scientifically unsubstantiated beliefs but none cover a broad spectrum of cognitions while also being up-to-date and unconstrained by theoretical limitations. There is also a debate about the number of separate types of belief. Thereby, reported here is the development and validation of a new multidimensional questionnaire measure of scientifically unsubstantiated beliefs in the general UK population. Method & Results. In Study 1, participants (N=393) completed a questionnaire containing a pool of 82 items covering nine facets of belief discernible conceptually within the existing research literature. Scree analysis followed by exploratory factor analysis indicated the existence of four empirically observable factors: belief in supernatural forces; belief in God and destiny; belief in alien visitation, monsters and conspiracies; and belief in consciousness beyond the body. Twenty-four items were selected as measures of these factors. Studies 2, 3 and 4 demonstrated the convergent and divergent validity of the four empirically-derived questionnaire subscales and their internal reliability. Conclusion. The resultant new Multi-dimensional Questionnaire of Scientifically Unsubstantiated Beliefs (MQSUB) is a psychometrically robust measure and comprises a comprehensive framework which can be used to systematically investigate the psychological and social concomitants of such beliefs
