Abstract: This article presents two studies in which the psychometric properties and validity of the Gudjonsson Suggestibility Scale (GSS) were further investigated. Results of the first study (N=40) indicate that the GSS has reasonable internal consistency Additionally, a modest, but significant test-retest stability was found for the GSS. As to the association between suggestibility and self-reported cognitive efficiency (i.e., metacognition measures), scores on the Yield dimension of the GSS were positively and significantly related to scores on the Dissociation Experiences Scale (DES), but not to scores on the Cognitive Failures Questionnaire (CFQ). In a second, experimental study (N=53), evidence was found for the predictive validity of the GSS. In that study, subjects saw a slide series and were then confronted with leading questions about the critical (emotional) slide. In addition, they completed the Yield scale of the GSS. A small but significant correlation was found between subjects' Yield scores on the GSS and their susceptibility to leading questions about the slide series.
