Linking obsessions to morality: A cross-cultural study among Turkish and Belgian university students

The present study examines the links between different types of morality and obsessions in university students from Leuven, Belgium (<i>N</i> = 252) and İstanbul, Turkey (<i>N</i> = 301) using validated scales for morality and obsessions. Belgium and Turkey were chosen as two exemplar cultural contexts expected, and in the current study found, to differ in the relative levels of individualizing and binding morality. We hypothesized that obsessions involving potential <i>harm</i> (e.g., aggressive obsessions) are cross-culturally associated with <i>individualizing</i> morals, and obsessions indicating <i>impurity</i> (e.g., contamination) are cross-culturally associated with <i>binding</i> morals. Moreover, we expected that cultural differences in the frequency of obsessions could be linked to differences in culturally prevalent moralities. As predicted, contamination obsessions were cross-culturally linked to binding morals. Also, the frequency of contamination obsessions was higher in the Turkish sample compared to the Belgian, which was predicted by higher levels of binding morals in Turkey. Doubts were cross-culturally endorsed at similar rates and were associated with individualizing morals. Aggressive obsessions were relatively more frequent in the Belgian compared to the Turkish sample, however-unexpectedly-these intrusions were not positively linked to either type of morality, neither in Belgium nor in Turkey. Taken together, these findings provide initial support for the role of morality in obsessive-compulsive disorder (OCD), at least for certain types of obsessions (contamination and doubts), as well as suggest that some differences in the moral foundations may play a role in explaining the prevalence of certain obsessions (i.e., contamination).
