Associations between Belief in Conspiracy Theories and the Maladaptive Personality Traits of the Personality Inventory for DSM-5

Conspiracy theories can be treated as both rational narratives of the world as well as outcomes of underlying maladaptive traits. Here, we examined associations between belief in conspiracy theories and individual differences in personality disorders. An Internet-based sample (N=259) completed measures of belief in conspiracy theories and the 25 facets of the Personality Inventory for DSM-5 (PID-5). Preliminary analyses showed no significant differences in belief in conspiracy theories across participant sex, ethnicity, and education. Regression analyses showed that the PID-5 facets of Unusual Beliefs and Experiences and, to a lesser extent, Suspiciousness, significantly predicted belief in conspiracy theories. These findings highlight a role for maladaptive personality traits in understanding belief in conspiracy theories, but require further investigation.

Compulsive Buying: Literature Review and Suggestions for Future Research

Compulsive buying is a serious, but under researched, aspect of consumer buying behaviour. Setting the review in a historical context, the review begins by addressing the earliest works on the subject and seminal papers by leading researchers in the field of compulsive buying. The review addresses the fact that Emil Kraepelin first identified compulsive buying in his 1915 textbook, before the subject faced an almost complete hiatus in terms of research until the late 1980s where the issue was addressed by a number of leading consumer behaviour researchers. The review will then proceed chronologically and thematically, addressing each issue and theme that has emerged from the literature. Previous directions of the research will be discussed, whilst guiding readers towards the current landscape of the research, and a suggestion of the next logical direction of the research.
