The Basic Empathy Scale (BES) has been internationally used to measure empathy. A systematic review including 74 articles that implement the instrument since its development in 2006 was carried out. Moreover, an evidence validity analysis and a reliability generalization meta-analysis were performed to examine if the scale presented the appropriate values to justify its application. Results from the systematic review showed that the use of the BES is increasing, although the research areas in which it is being implemented are currently being broadened. The validity analyses indicated that both the type of factor analysis and reliability are reported in validation studies much more than the consequences of testing are. Regarding the meta-analysis results, the mean of Cronbach’s α for cognitive empathy was 0.81 (95% CI: 0.77–0.85), with high levels of heterogeneity (I² = 98.81%). Regarding affective empathy, the mean of Cronbach’s α was 0.81 (95% CI: 0.76–0.84), with high levels of heterogeneity. It was concluded that BES is appropriate to be used in general population groups, although not recommended for clinical diagnosis; and there is a moderate to high heterogeneity in the mean of Cronbach’s α. The practical implications of the results in mean estimation and heterogeneity are discussed.

Traditionally, research on addictive behaviors has been based on the study of their risk factors, with impulsivity being the main risk factor. However, this study aims to approach this topic from the analysis of decision making. According to the prospect theory, low levels of loss and risk aversion will increase the probability of showing addictive behaviors. A systematic review of the possible relationships between these behaviors and prospect theory was carried out. To this end, the works that have studied loss and risk aversion in populations with addictive behaviors to date (N = 15) were compiled. Apart from other eligibility criteria, the selection process was only performed with studies that included the prospect theory or cumulative prospect theory, in English or Spanish, since 1979. WoS, Scopus, Dialnet and PsycInfo were the information sources selected. For this purpose, PRISMA guidelines have been followed. It was found that users of addictive substances show less loss aversion than nonusers. These results cannot be transferred to pathological gamblers. The significance of this work for future research and the implementation of prevention and intervention programs is highlighted. The results show an approach to addictions from a novel perspective.

Background and Objectives: Animal-assisted therapies have been utilized in various profiles to improve people’s quality of life. This systematic review aims to assess the impact of dog-assisted therapies (DAT) on children and adolescents with Autism Spectrum Disorder (ASD). The benefits provided, the feasibility of implementation, and potential limitations are analysed. Methods: An exhaustive search was carried out in the following databases: Web of Science (WoS), Scopus, ERIC, PubMed, PubPsych, CINAHL, PsycInfo and Dialnet. The procedure was preregistered on PROSPERO. Results: This review included 19 scientific articles. Of these, 84% suggest that DAT has a positive impact on communication and social interaction during the development of children and adolescents diagnosed with ASD. The dog is often perceived as a communication facilitator that serves as a reinforcer, capturing the individual’s attention. Emotional benefits have also been reported, including reducing stereotyped and self-harming behaviours. Additionally, an increase in smiling frequency and self-esteem levels was observed. Conclusions: These findings highlight the potential of DAT as a component of socio-educational intervention for children and adolescents diagnosed with ASD. However, further research is necessary due to the limited sample sizes in the studies reviewed.

Prosociality is essential in human interactions, characterized by voluntary behaviors aimed at benefiting others. Promoting such behaviors is indispensable for human relationships. Studies have demonstrated positive effects of interpersonal synchrony interventions through musical sessions. Some authors suggest that the joint creation of music facilitates prosocial behaviors (PB). This review aims to determine whether evidence supports the idea that participation in a musical interpersonal synchrony experience improves PB. A systematic review of 12 selected articles was conducted. The search was carried out in databases such as WoS, Scopus, PubMed, Dialnet, Elsevier, and Eric. Results indicate that music, as a tool, creates an optimal environment for mimesis and group participation, which can enhance prosociality. Controlling variables such as sample size, population type, measurement instruments, techniques, and session design is necessary for future research. It is concluded that interpersonal synchrony through music appears to improve prosociality, although more robust studies are required.

Limitations in some emotional characteristics that are conceptualized in the definition of emotional intelligence can be seen among people with autism spectrum disorder. The main objective of this study is the analysis of the effectiveness of interventions directed to enhance emotional recognition and emotional regulation among this specific population. A systematic review was carried out in databases such as Psycinfo, WoS, SCOPUS, and PubMed, identifying a total of 572 articles, of which 29 met the inclusion criteria. The total sample included 1061 participants, mainly children aged between 4 and 13 years. The analyzed interventions focused on improving emotional recognition, with significant results in the identification of emotions such as happiness, sadness, and anger, although some showed limitations in the duration of these effects. The most used programs included training in facial recognition, virtual reality, and the use of new technologies such as robots. These showed improvements in both emotional recognition and social skills. Other types of interventions such as music therapy or the use of drama techniques were also implemented. However, a gender bias and lack of consistency between results from different cultures were observed. The conclusions indicate that, although the interventions reviewed seem effective, more research is needed to maximize their impact on the ASD population.

The assessment of empathy advanced substantially with the introduction of the Basic Empathy Scale (BES), a widely used self-report instrument. However, its abbreviated iteration (BESB) has not been systematically examined in young Hispanic adults within higher education contexts. This study aimed to adapt and validate the BES-B for use in university students. A non-probability sample of 755 Peruvian students from diverse academic disciplines participated in the study, with women representing 56.9% of the sample. The internal structure of the scale was examined through analyses of dimensionality, reliability, and measurement equivalence, as well as clinimetrically relevant parameters derived from comparisons across competing measurement models. Results supported a two-factor structure with minor cross-loadings, with satisfactory factor loadings indicating adequate representation of affective and cognitive empathy. Measurement invariance by sex was established, including residual equivalence, and metric equivalence with previous studies indicated greater alignment with adolescent than with child samples. Factor complexity and interfactor correlations were mild and theoretically consistent. Reliability estimates were approximately 0.72, suggesting that score differences greater than 14 points are statistically uncommon. The findings support the use of the adapted BES-B as a reliable and valid measure of empathy in undergraduate populations.
