Highlights A dominance analysis of psychological variables associated to BD is proposed. Positional, inter-individual and intra-individual factors were investigated. The variables most associated to BD were enhancement motives and drinking identity. The second order variables associated with BD were subjective norm and social motives. Prevention actions may benefit of specifically targeting inter-individual variables.

This research aimed to test the moderating effect of people's initial position to blood donation on the actual acceptance to donate blood in a door-in-the-face situation. This position (attitude, self-importance, normative beliefs) was measured one month prior to the request (Study 1, N = 99) or immediately before (Study 2, N = 80). The results revealed that the doorin-the-face effect is moderated by the importance of blood donation to the self, all the more so when the position is made salient. This highlights the specific character of blood donation in France and the centrality of the importance of donating for the self at the heart of the DITF technique. These results offer new insights into the conditions that must be met to achieve acceptance to donate blood after an initial refusal.

Highlights This study focused on combined binge drinking and cannabis use in college students. Cannabis use and binge drinking had an additive effect on cognition. This consumption pattern contributed to memory and executive impairments. Binge drinkers had a heterogeneous cognitive profile regardless of cannabis use. Cannabis use should be assessed in binge drinkers to adapt prevention strategies.

This study investigates the combination of several psychological factors related to tobacco smoking to identify smokers’ psychological profiles among French university students. A cluster analysis was performed on smoking motives, psychosocial variables, and the smoker identity ( N = 909). Five profiles were identified and then compared regarding tobacco dependence and motivations to quit. “Normative” and “sociohedonist smokers” are characterized by two distinct social factors (normative influences and social motives) and moderate dependence. “Dependent identified smokers” have higher levels of dependence motives, smoker identity and tobacco dependence associated with low motivations to quit. “Inconsistent smokers” have weak smoker identity and weak smoking motives, a strong perceived control over resisting smoking, low dependence and motivations to quit. “Coping smokers” have strong sedative and addictive motives and exhibit moderate dependence and motivations to quit. This research encourages prevention programs to consider the diversity of student smokers with strategies adapted to their psychological profiles.

People with disabilities remain discriminated against, especially those living with mental disabilities compared to those living with physical disabilities, which might be rooted in a dehumanization process. Because there is evidence pointing to a tendency to dehumanize people with mental disabilities, the aim of this research (N = 559) was to demonstrate the differences in humanness attributions to people with mental and physical disabilities. The results showed that people with mental disabilities are perceived as being less human than people with physical disabilities, whether it be on blatant or subtle measures of dehumanization. More specifically, whereas dehumanization was clearly evidenced for people with mental disabilities, there was no evidence found concerning the dehumanization of people with physical disabilities. The latter were even attributed more humanness-related characteristics than people without physical disabilities. Therefore, contrasted humanness attributions between people labeled as having mental or physical disabilities should be taken into consideration if the image of people with disabilities is to change.
