Since its emergence in 1976, the JCR index—alongside other similar indices developed subsequently, such as the SJR—has become the standard criterion for assessing the impact and, indirectly, the quality of scientific journals. However, an increasing number of critics question the exclusive use of this metric as the sole means for assessing the impact and quality of scientific publications. Criticisms include the fact that it does not provide individualized information for each article, it does not take citation distributions into account, and that more citations do not always equal higher quality. The aim of the present article is to provide a critical analysis of the alternatives currently being proposed to assess the scope, impact, and quality of scientific publications on an individual basis, while also including criteria that are not only quantitative (metrics based on citation counts), but also qualitative (such as number of mentions on social media, in the press, or in legislation, etc.).

Extremism and radicalisation pose significant threats to national security and socio-political stability, particularly in Western countries. Despite the extensive scientific literature addressing these phenomena from various perspectives, existing empirical research lacks cohesion due to differing theoretical models. This systematic review aims to unify recent empirical research on psychological factors associated with extremism and radicalisation, focusing on empirical studies across diverse cultural and socio-political contexts. Key findings indicate that certain personality traits—specifically, low openness to experience and high conscientiousness—may increase susceptibility to extremist beliefs. Additionally, quest for significance seems to stand out as a powerful motivator for radicalisation.

In 2007, Papeles del Psicólogo published a monograph on psychology and addictions that presented the psychological foundations of addictive behaviors that supported preventive interventions and psychological therapeutic approaches supported by empirical evidence. Eighteen years later, the health, economic, and social importance of problems arising from drug use and other addictive behaviors remains very high. Since then, other types of phenomena (new technologies, social media, etc.) have emerged and gained prominence, adding to traditional addictive behaviors and making analyses of these types of behaviors and their possible solutions even more difficult.
