RESUMO
Previous research has stated a relationship between sexist ideologies and humour appreciation. However, most research has been done in North America and Europe. In the present study, we aimed to approach in an exploratory way to the social perceptions of sexist humour in Costa Rica. Data was gathered through an online survey, participants (N = 323; 220 females) completed measures to characterise expressions of sexist humour. The main measures included perceived funniness, frequency and means of exposure, and perceived offensiveness, as well as completing the Ambivalent Sexism Inventory (ASI). Overall, previous exposure to this kind of humour was remarkably high. No significant differences were observed between women's and men's perceptions of the frequency, means and places of exposure, but emotional and behavioural reactions to sexist humour were gender-based. Women reported higher displeasure, more confrontation and felt angrier and more offended than men when exposed to this type of humour. Data support existing evidence of the relationship with sexist ideology. Specifically, hostile sexism was found to be a significant predictor of perceived funniness and offensiveness of the sexist jokes. An interaction effect between hostile sexism and the sex of participants was found, showing that as hostile sexism increased, perceived offensiveness decreased, but more rapidly for men. Results are discussed considering the practical implications and limitations, as well as the need for more research in the Latin American context.

The present study aimed to evaluate the measurement invariance of the Obsession with COVID-19 Scale (OCS) among seven Latin American countries: Bolivia, Brazil, Cuba, El Salvador, Guatemala, Paraguay, and Uruguay. Although the OCS has been used in several countries and languages, there is a need for approaches that better integrate the cross-cultural equivalence of the scale. A total of 3185 people participated in the study. The results indicated the presence of a unidimensional structure and good reliability indices for the OCS in each country. The alignment method indicated that the OCS is an invariant measure of COVID-19 obsession among the populations of seven Latin American countries. The findings based on IRT analysis indicated that all OCS items had adequate discrimination and difficulty parameters. The findings contribute to the understanding of the internal structure of the scale in different countries at the same time, something that has been pending evaluation.
RESUMO
OBJECTIVE: To examine the association between family environment variables (parenting styles, family meal atmosphere), gender-based stereotypes and food intake in Latin American adolescents. DESIGN: Structural equation modelling applied to cross-sectional data, 2017. SETTING: Urban and rural sites of San José, Costa Rica. PARTICIPANTS: n 813; 13-18 years old. RESULTS: Data suggest direct associations between gender-based stereotypes and intake of fruits and vegetables (FV) (ß = 0·20, P < 0·05), unhealthy foods (fast food (FF)) (ß = -0·24, P < 0·01) and ultra-processed foods (ß = -0·15, P < 0·05) among urban girls; intake of legumes among rural girls (ß = 0·16, P < 0·05) and intake of sugar-sweetened beverages (SSB) among rural boys (ß = 0·22, P < 0·05). Family meal atmosphere was associated with legume intake (ß = 0·19, P <·05) among rural girls. Authoritative parenting style was associated with FV intake (ß = 0·23, P < 0·05) among urban boys and FF intake (ß = 0·17, P < 0·05) among urban girls. Authoritarian parenting style was associated with FV consumption (ß = 0·19, P < 0·05) among rural boys, and with SSB and FF consumption (ß = 0·21, P < 0·05; ß = 0·14, P < 0·05, respectively) among urban girls. CONCLUSIONS: Findings are the first to describe the complex family environment and gender-based stereotypes within the context of a Latin American country. They emphasise the need for culturally relevant measurements to characterise the sociocultural context in which parent-adolescent dyads socialise and influence food consumption.

Little is known about how parenting styles can influence the adolescent's consumption of sugar-sweetened beverages (SSB), fruits and vegetables (FV) and beans in Latin America. This study uses hierarchical moderated regression models to examine such association by area of residence, sex of the parent and of the adolescent in Costa Rica. Results showed that fathers' authoritarian style was significantly associated with lower intake of sugar-sweetened beverages (SSB) among boys (b = -0.163, p = 0.050), but not girls (b = 0.097, p = 0.114) while mother's authoritarian style was associated with lower SSB intake among girls (b = -0.138, p = 0.031), but not boys (b = 0.159, p = 0.059). Fathers' authoritative style was associated with higher consumption of fruits and vegetables (FV) among boys in rural areas (b=0.440, p= 0.017), but this association was not significant for girls (b=-0.033, p= 0.800) in rural areas or for either gender in urban areas. Parenting styles of the mothers' and fathers' were not significantly associated with Costa Rican adolescent bean consumption, in general or for any of the subgroups. Findings suggest an intersectionality in the effects of parentchild interactions by child and parent sex, cultural and geographic context, and the eating behaviors examined.

We examined the influence of perceived parental sexual values, religiosity, and family environment on young adults' sexual values from the United States (n = 218), Spain (n = 240), Costa Rica (n = 172), and Peru (n = 105). On average, and across the four national groups, the messages young adults received from their parents about broad domains of sexual behaviors (masturbation, non-intercourse types of heterosexual sexual activity, premarital sex, same-sex activity, and cohabiting) were unequivocally restrictive. By contrast, across the four groups, young adults on average held rather permissive sexual values and their values differed significantly from those of their parents. Moreover, the nature of perceived parental sexual values (restrictive vs. permissive) was not associated significantly with young adults' sexual values, age of sexual debut, or number of sexual partners. Comparatively, Spanish young adults held the most permissive sexual values, whereas US young adults held the most restrictive sexual values. Religiosity was the strongest predictor of young adults' sexual values, followed by perceived parental sexual values and influence. In conclusion, it appears that despite having perceived restrictive parental messages about sex, these young adults currently hold permissive sexual attitudes, thus calling into question the influence parents actually have on their adult children's sexual values.

Previous cross-cultural studies have found differences in food attitudes. For example, Americans are more concerned about weight gain than people from France and India. This study aimed to add on the literature on cross-cultural differences in food attitudes by comparing Euro-Americans with Costa Ricans on three different food attitudes: concern about gaining weight, food negativity, and the belief in the link between diet and health. This study also analyzes the implications of food attitudes on well-being. Specifically, within and across cultures, analyses were done to test the relationship between food attitudes and both anxiety and depression. Results showed that Costa Ricans are significantly less concerned about weight and less food negative than Euro-Americans. In further analyses an interaction was revealed, in which Costa Ricans that are high on weight concern but low on food negativity show lower levels of depression, compared to Euro-Americans. Results and implications for further research are discussed.

OBJECTIVE: To generate normative data for the Verbal Fluency Test (VFT) and the Boston Naming Test (BNT) in the Costa Rican population. METHOD: The sample consisted of 563 healthy older people (aged 59-90 years). Polynomial multiple regression analyses were run to evaluate the effects of the age, sex, and education variables on VFT and BNT scores. RESULTS: The results showed a significant linear effect of education on the four-letter VF scores and an effect of sex on the letter P score, with females performing better than males. The explained variance ranged from 20.9% to 28.3%. A linear effect of age and education was also found for the four semantic VF scores, with scores decreasing with increasing age and lower education. The sex variable was significant for all semantic categories, with females performing better than males except in the animal category. The explained variance ranged from 21.7% to 30.9%. In the BNT, a linear effect of education was found, so that the more education, the better the score. In addition, a sex effect was also found, with males having higher scores than females. The predictors of the model explained 9.6% of the variance. CONCLUSIONS: This is the first study that generates normative data for the VF and BNT in the Costa Rican population over 59 years of age based on demographic variables. The use of these normative data will help clinicians in Costa Rica to better understand language functioning in the elderly, allowing for better classification and diagnosis in the future.
RESUMO
This study aimed to characterize the network structure of pandemic grief symptoms and suicidal ideation in 2174 people from eight Latin American countries. Pandemic grief and suicidal ideation were measured using the Pandemic Grief Scale and a single item, respectively. Network analysis provides an in-depth characterization of symptom-symptom interactions within mental disorders. The results indicated that, "desire to die," "apathy" and "absence of sense of life" are the most central symptoms in a pandemic grief symptom network; therefore, these symptoms could be focal elements for preventive and treatment efforts. Suicidal ideation, the wish to die, and the absence of meaning in life had the strongest relationship. In general, the network structure did not differ among the participating countries. It identifies specific symptoms within the network that may increase the likelihood of their co-occurrence and is useful at the therapeutic level.
RESUMO
OBJECTIVES: The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries. METHODS: A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. RESULTS: The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-SCORE-10 scores indicated that participants from Cuba, Uruguay and El Salvador had the most positive perceptions of government actions to address the pandemic. Thus, the underlying construct of perception of government actions was equivalent in all countries. CONCLUSION: The results show the importance of initially establishing the fundamental measurement properties and MI before inferring the cross-cultural universality of the construct to be measured.
RESUMO
The present study explored the predictive capacity of fear of COVID-19 on the intention to be vaccinated against COVID-19 and the influence in this relationship of conspiracy beliefs as a possible mediating psychological variable, in 13 Latin American countries. A total of 5779 people recruited through non-probabilistic convenience sampling participated. To collect information, we used the Fear of COVID-19 Scale, Vaccine conspiracy beliefs Scale-COVID-19 and a single item of intention to vaccinate. A full a priori Structural Equation Model was used; whereas, cross-country invariance was performed from increasingly restricted structural models. The results indicated that, fear of COVID-19 positively predicts intention to vaccinate and the presence of conspiracy beliefs about COVID-19 vaccines. The latter negatively predicted intention to vaccinate against COVID-19. Besides, conspiracy beliefs about COVID-19 vaccines had an indirect effect on the relationship between fear of COVID-19 and intention to vaccinate against COVID-19 in the 13 countries assessed. Finally, the cross-national similarities of the mediational model among the 13 participating countries are strongly supported. The study is the first to test a cross-national mediational model across variables in a large number of Latin American countries. However, further studies with other countries in other regions of the world are needed.

The role of perceived social support in the acculturation process of immigrants remains unclear. In this study, we jointly evaluated the associations between acculturative stress and negative emotions associated with discrimination as antecedents of anxiety, depression, and stress symptoms in 283 immigrants living in Chile. Three competing models were tested via structural equation modelling to assess (1) the association among these variables and mental health symptoms and (2) to clarify the role of perceived social support. The third model was theoretically more adequate, showed a better fit, and explained 42.7% of the variance of mental health symptoms. In this model, perceived social support was associated with acculturative stress by reducing mental health symptomatology. Moreover, a direct relationship and an indirect relationship were found between acculturative stress (through negative emotions associated with discrimination) and mental health symptomatology. These results contribute to the understanding of the acculturation process experienced by immigrants in Chile and provide empirical evidence to be used to improve migration policies.

Parenting styles are a risk factor for adolescents overweight/obesity worldwide, but this association is not well understood in the context of Latin America. This study examines the association between the parenting styles of mothers and fathers and the risk of overweight/obesity among Costa Rican adolescents. Data are cross-sectional from a sample of adolescents (13-18 years old) enrolled in ten urban and eight rural schools (n = 18) in the province of San José, Costa Rica, in 2017. Hierarchical logistic regression analyses were performed to assess the likelihood of adolescents being overweight according to the mothers' and fathers' parenting styles. A significant association was found between the risk of adolescent overweight/obesity and the paternal authoritarian style only in rural areas (B = 0.622, SE = 0.317, Wald = 3.864, ExpB = 1.863, p = 0.04), and between said risk and the paternal permissive style only in male adolescents (B = 0.901, SE = 0.435, Wald = 4.286, ExpB = 2.461, p = 0.038). For maternal parenting styles, no associations reached significant levels once logistic regression models were adjusted for the fathers' parenting styles. These findings underscore the importance of further studying the role of fathers' paternal parenting styles on Latin American adolescent weight outcomes. Expanding our understanding of the parenting styles of fathers has important implications for the design and implementation of culturally- and gender-appropriate family interventions.

BACKGROUND: Whereas parental feeding styles (PFS) influence children's diet, less is known about this relationship in adolescents. METHODS: A cross-sectional study in 686 Costa Rican adolescents (13-18 years) evaluated 4 validated PFS scores: healthy eating verbal encouragement; scolding; directly controlling diet; instrumental/emotional. Diet was evaluated through 3-day food records, deriving a Traditional Costa Rica Adolescents Diet Score (TCRAD). Excess weight (EW) measured by BMI was dichotomized following standards. Regression-based mediation analysis estimated the overall and sex-stratified odds ratios of EW for natural direct (NDE), natural indirect (NIE), and total effects (TE) of the pathway PFSâTCRADâEW. RESULTS: A one-unit increase in the direct control PFS score was associated with higher EW odds overall [(TE: 1.55; 95% CI: 1.04-2.31; p-value = 0.033), (NDE: 1.52; 95% CI: 1.02-2.27; p-value = 0.039)], and in boys [(TE: 2.13; 95% CI: 1.04-4.38; p-value = 0.039), (NDE: 2.10; 95% CI: 1.03-4.31; p-value = 0.042)]. Non-significant mediation by TCRAD was observed for the healthy eating verbal encouragement PFS overall (p-value = 0.06). Associations for the instrumental/emotional and scolding PFS were not significant. CONCLUSIONS: Direct diet control from parents may contribute to adolescents' excess weight, particularly among boys. Parents encouraging healthy eating might support adolescents' healthy weight through a healthy diet. Longitudinal research should clarify the association between PFS and diet-related outcomes among diverse adolescents.

BACKGROUND: Acculturation stress is associated with poorer physical and mental health and a lower level of psychological well-being. The causes of acculturation stress are diverse, but most are similar in the migrant population. Despite the importance of evaluating this variable, few studies have reported culturally adapted and validated instruments for specific populations. Based on this, the aim of this study was to evaluate the psychometric properties of a short scale for the evaluation of acculturation stress (EBEA). METHODS: Two studies were conducted, involving 1725 first-generation Colombian and Peruvian migrants living in Chile, between the ages of 18 and 60 years. In addition to the EBEA and as evidence of validity, the Beck Anxiety Scale and the WHOQOL-BREF psychological health domain were applied. A confirmatory factor analysis was carried out, and the reliability and nomological validity were evaluated. RESULTS: The results in both studies indicated that the scale presents a factorial structure of three dimensions: (a) the stress derived from the preparation and departure from the country of origin, (b) the stress produced by socioeconomic concerns in the host country, and (c) the tensions typical of adaptation to sociocultural changes or Chilean society. The reliability coefficients and the analysis of their nomological validity were very good. CONCLUSIONS: The EBEA is a measure that offers quick, useful screening for researchers who need a short measure for research among migrants. This tool contributes to the work of education, prevention, and intervention in the field of general health and migrants' mental health.
RESUMO
Objective. The study aimed to develop and test the validity and reliability of a gender-based food intake stereotype scale (GBFISS) to further the understanding of gender stereotype influences on food intake. Design. Two cross-sectional studies were conducted among adolescents. In the first one (n = 611), exploratory and confirmatory factor analyses were performed on subsamples to identify and cross-validate the scale's structure. Evidence of concurrent validity (correlation with sexism) was also examined. In the second study (n = 813), confirmatory factor analysis was conducted to confirm the scale's dimensionality on a different sample. Further evidence of construct validity (correlations with food intake and social desirability) was examined. Invariance was tested for different features as well. Main outcome. The Gender-Based Food Intake Stereotype Scale. Results. Factor analyses on the first and second studies helped identify and confirm the GBFISS as a three-dimensional scale. The studies also provided evidence of construct validity. Support for invariance by gender and age was found, and reliability was acceptable. Conclusion. The evidence suggests that the GBFISS is valid and reliable. Further research is recommended. The contribution of gender stereotypes, as measured by the GBFISS, to well-established health behavior models should be examined.
RESUMO
Knowledge of evolutionary influences on patterns of human mating, social interactions, and differential health is increasing, yet these insights have rarely been applied to historical analyses of human population dynamics. The genetic and evolutionary forces behind biases in interethnic mating and in the health of individuals of different ethnic groups in Latin America and the Caribbean since the European colonization of America are still largely ignored. We discuss how historical and contemporary sociocultural interactions and practices are strongly influenced by population-level evolutionary forces. Specifically, we discuss the historical implications of functional (de facto) polygyny, sex-biased admixture, and assortative mating in Latin America. We propose that these three evolutionary mechanisms influenced mating patterns, shaping the genetic and cultural landscape across Latin America and the Caribbean. Further, we discuss how genetic differences between the original populations that migrated at different times into Latin America contributed to their accommodation to and survival in the different local ecologies and interethnic interactions. Relevant medical and social implications follow from the genetic and cultural changes reviewed.

RESUMO
BACKGROUND: In Latin America, more than 80% of adolescent girls are physically inactive. Inactivity may be reinforced by female stereotypes and objectification in the Latin American sociocultural context. METHODS: We examined the influence of objectification on the adoption of an active lifestyle among 192 adolescents (14 and 17 years old) from urban and rural areas in Costa Rica. Analyses of 48 focus-groups sessions were grounded in Objectification Theory. RESULTS: Vigorous exercises were gender-typed as masculine while girls had to maintain an aesthetic appearance at all times. Adolescents described how girls were anxious around the prospect of being shamed and sexually objectified during exercises. This contributed to a decrease in girls' desire to engage in physical activities. Among males, there is also a budding tolerance of female participation in vigorous sports, as long as girls maintained a feminine stereotype outside their participation. CONCLUSION: Self-objectification influenced Costa Rican adolescent girls' decisions to participate in physical activities. Interventions may include: procuring safe environments for physical activity where girls are protected from fear of ridicule and objectification; sensitizing boys about girl objectification and fostering the adoption of a modern positive masculine and female identities to encourage girls' participation in sports.

Resumen Se ha sugerido que la práctica profesional de un instrumento musical esta relacionada con mejores puntajes en tareas de funciones ejecutivas. Con el fin de examinar sistemáticamente esta hipótesis se realizó un metaanálisis para identificar el efecto de la interpretación de un instrumento en las funciones ejecutivas, así como las variables que podrían moderar dicho efecto. El metaanálisis incluyó estudios empíricos que: (1) compararon los puntajes en medidas de funciones ejecutivas entre músicos y no músicos; (2) reportaron las medias y desviaciones estándar; (3) el grupo de comparación no recibió entrenamiento musical; y (4) los participantes no presentaron discapacidad motora o cognitiva. Se identificó que los músicos, en comparación con los no músicos, muestran mejores puntajes en tareas de funciones ejecutivas (d = .712). Los resultados apoyan la hipótesis de que la práctica de un instrumento musical está relacionada con mejores puntuaciones en tareas de funciones ejecutivas.
Abstract Nowadays, it is widely accepted that experience can modify multiple aspects of the functioning and structure of the brain; however, there is still a long way to go to understand the mechanisms behind these modifications. In order to understand the relationship between experience and brain plasticity, models and paradigms have been adapted from cognitive neurosciences; one of them has been music training. In the last decades, this paradigm has strengthened because it allows us to understand the structural and functional modifications produced by training. It has been demonstrated that musicians compared to non-musicians present larger sizes of specific brain regions, in particular, the prefrontal cortex, which is associated with a better performance in executive functions tasks. In addition, long-term neurophysiological changes have been identified in people who play an instrument. A relationship between playing an instrument and better performance in executive functions has been identified. However, the evidence of this effect is contradictory. Executive functions are a series of general control processes that help regulate thinking and behavior. Some research indicates that learning an instrument is associated with better performance in working memory, but not regarding tasks related to inhibitory control and cognitive flexibility. However, other studies have revealed significant differences between musicians and non-musicians, both in working memory and tasks of cognitive flexibility as well as in inhibitory control. It is possible that the contradictory results are due to the methodological diversity through which this topic has been addressed, since some studies have carried out experimental and quasi-experimental designs, and others have developed correlational approaches. In addition, different theoretical models have been used to evaluate executive functions. For this study, we work with the theoretical model of Miyake et al. (2000), which is a solid theoretical-empirical proposal about three clearly differentiable executive functions: inhibitory control, cognitive flexibility, and working memory. A meta-analysis was performed with the purpose of identifying the effect of playing an instrument on executive functions as well as identifying the moderator variables. By doing this, we wanted to clarify the problem in question and the controversial results; therefore, empirical studies comparing musicians against non-musicians were included. The comparison group should not have been exposed to musical training, the participants should not present motor or cognitive disabilities, and finally, studies should report means and standard deviations for the scores on executive functions tasks. We included papers published between January 2000 and July 2017. The moderator variables studied were: age in months at the time of evaluation, age at which training began, and total years of training. The coding strategy allowed us to identify a total of 42 294 articles. The titles and abstracts were analyzed and those that did not meet the inclusion criteria were eliminated. This procedure allowed the detection of 24 articles for future analysis, and 12 out of them were finally selected. These 12 articles contributed to 60 effect sizes and 513 participants. The results showed that musicians have a better performance in executive functions tasks when they are compared to non-musicians, d = .712, n = 60, IC95% = (.57; .85), p < .0001. Additionally, the analysis of moderating variables revealed that the practice of an instrument equally benefits all executive functions, and the most important benefit occurs in older adults and children. Results support the hypothesis that the high level of difficulty involved with learning to play an instrument can influence a better performance in executive functions tasks. Our study points out the need of designing research that allows the scientific community to investigate the effect of prolonged musical training over time.
