Emotional intelligence (EI) is a fundamental skill related to different aspects of human life, such as psychological well-being or mood states. The present study has a triple objective: first, to explore the psychometric properties of the TMMS-24 in three Spanish-speaking countries (Argentina, Ecuador, and Spain); second, to examine the relation of EI with mood and avoidance of responsibility; and finally, to analyse the influence of sex, age and national differences on EI. The relevance of this study is given by the need for tools to assess EI in different cultures. A sample of 1048 adults (M_age = 21.11 years, SD = 5.84; 52.3% male) was selected by convenience sampling. The psychometric properties of the TMMS-24 were adequate, and the Spanish sample showed lower levels of EI than the Argentinian and Ecuadorian ones. EI was associated with mood and the avoidance of responsibility, with higher levels in women in all cases. Regarding the national and sex-specific differences, the Spanish sample showed significant differences in attention and repair, with men exhibiting higher scores in attention and women having higher scores in repair. In the Argentinean sample, no significant differences were found, and in the Ecuadorian one, women presented higher scores in attention than men. The TMMS-24 can be considered a useful, practical tool to assess EI in adults in different cultures and with different languages.

The aim of this study was to analyze the psychometric properties of the Spanish version of the MOOD Questionnaire in child population. This instrument was developed to cover the existing gap in the evaluation of mood in children. The MOOD was administered to 1489 children (mean age = 9.11 years old). The psychometric properties of the Mood questionnaire are adequate. Moreover, the questionnaire was associated with somatic complaints and emotional awareness. According to the results of the study, the use of this diagnostic tool with Spanish children seems justified.

The scale of positive and negative experiences (SPANE) assesses emotional responses and their frequency of manifestation in recent weeks. This scale has been validated in different countries and populations but not in Spanish adolescents. The aim was to evaluate the psychometric properties of SPANE in two samples: (1) Sample I included 797 adolescents (M = 15.5 years old, SD = 0.68, 54.2% female) and, (2) Sample II included 1433 adolescents (M = 13.7 years old, SD = 1.27, 53.2% female). Finally, a subsample from sample II was analyzed in different stages (after six and 12 months) with 298 adolescents (M = 13.7 years old, SD = 1.13, 58.7% female). The results obtained have adequate levels of reliability and validity that seem to justify the use of this diagnostic tool in the Spanish adolescent population.

Background: The aim of this study was to analyse the psychometric properties of the Somatic Complaints List (SCL) in Spanish child and adult populations. This instrument assesses the frequency with which people experience and feel pain such as stomach ache and headache, among others. It has been validated in different countries and languages (Dutch, English, and Persian), showing adequate psychometric properties. Nevertheless, it has never been validated in a Spanish context. Method: For the adaptation and validation, we used two different samples: 1423 children, age ranging from 8 to 12 years old, selected from 12 primary and secondary schools at 7 locations in the Valencian Community, Spain (age = 9.11 years, SD = 1.27; 52.4% female); and 940 adults, age ranging from 18 to 56 years old (age = 32.3 years, SD = 11.62; 64% female). Results: The Spanish adaptation of the SLC showed adequate levels of reliability and validity. Conclusions: The empirical evidence seems sufficient to justify using this diagnostic tool with Spanish children and adults.

This study validates the Mood Questionnaire for adults in three Spanish-speaking countries: Argentina, Ecuador, and Spain. It then analyzes the influence of gender and cultural differences on mood, and whether there is a relationship between mood, emotional intelligence, and the Avoidance of Responsibility. A convenience sample of 1048 adults, with a middle-class socioeconomic background, was selected from three Spanish-speaking countries (Spain, Argentina, and Ecuador). The psychometric properties of the Mood Questionnaire are adequate, which is particularly interesting given the need for transcultural tools to evaluate moods. Moreover, the mood was associated with avoidance of responsibility and emotional intelligence. In addition, differences in mood were observed according to country and gender. These findings are interesting because the Spanish version of the Mood Questionnaire has been validated for children but not for adults, and it compares three Spanish-speaking countries. The use of this diagnostic tool with Spanish adults can be justified according to these results.
