the Palestinians. The results of the study, which was performed with a Spanish sample (N = 319), showed that there were no differences in the evaluation of the group according to the group evaluated, although there were differences according to the manipulation of the news item: in both conditions in which one group attacked another, the group evaluated was rated more negatively than the control group. The results also showed that both emotions and stereotypes mediated the effects of framing on prejudice. These results suggest that the participants’ attitude seems to depend more on the violent framing of the news items than on the role assigned to each group and that emotional processes and stereotypes are what regulate these attitudes.

The theoretical literature about affectivity shows its influence over positive and negative behaviour. This study analyses the impact of affectivity on the behaviour of Portuguese adolescents, as this knowledge is considered relevant to promoting skills and decreasing risky behaviours in adolescents. A total of 696 students (M = 15.22 years old; SD = 1.4) participated in this study by responding to the PANAS-N (Positive and Negative Affect Schedule) and SDQ (Strengths and Difficulties Questionnaire). The former measures the level of affect while the latter measures prosocial behaviours, emotional symptoms and behavioural problems. The results showed that positive affect positively influences prosocial behaviour. Emotional symptoms and behaviour problems are negatively affected by positive affect, and positive symptoms and behaviours by negative affect. Moreover, boys had higher scores on behaviour problems, while girls had higher scores in prosocial behaviour and emotional symptoms. For these reasons, affectivity should be considered in programmes to reduce behaviour problems and emotional symptoms.

of beliefs, attitudes, norms, roles and values organized around a theme). One of these syndromes, individualism-collectivism, distinguishes collectivist cultures, which prioritize collective over individual interests, from individualist cultures, which value individual autonomy, achievement and freedom. These dimensions intersect with the horizontal-vertical syndrome, where verticality means the preference for a society organized by hierarchies, in contrast to a horizontal culture, which privileges equality. This paper explores these dimensions using a new instrument in a sample of 990 participants from four regions in Mexico. The results of exploratory and confirmatory factorial analyses show four theoretically congruent factors with adequate levels of internal consistency reaching metric equivalence criteria in three of the four samples. The scores show greater support for horizontal individualism and less support for vertical collectivism. These results are discussed within the context of a cultural shift towards individualism.

With the objective of theoretically and psychometrically updating the Regional Identity Scale (RIS) proposed by Zúñiga and Asún in 2004 and expanding the population for which it shows evidence of validity, a revision and revalidation of this instrument was performed via two studies. The first study included 1,113 university students from four regions of Chile, and the second included 1,200 adults from the same regions. Both samples were obtained via a random design through multistage conglomerates. The results enable us to propose a new version of the original scale (RIS-2) with suitable reliability indexes, solid evidence of both convergent validity and internal structure validity, and items with satisfactory psychometric quality. Furthermore, we verify the presence of a multifactor structure with three highly correlated dimensions. We conclude that the RIS-2 is a reliable, valid and conceptually broader instrument than the preceding version, so it is a useful tool to measure the intensity of regional identity in both university students and the adult population
