Parental burnout is a unique and context-specific syndrome resulting from a chronic imbalance of risks over resources in the parenting domain. The current research aims to evaluate the psychometric properties of the Spanish version of the Parental Burnout Assessment (PBA) across Spanish-speaking countries with two consecutive studies. In Study 1, we analyzed the data through a bifactor model within an Exploratory Structural Equation Modeling (ESEM) on the pooled sample of participants (N = 1,979) obtaining good fit indices. We then attained measurement invariance across both gender and countries in a set of nested models with gradually increasing parameter constraints. Latent means comparisons across countries showed that among the participants’ countries, Chile had the highest parental burnout score, likewise, comparisons across gender evidenced that mothers displayed higher scores than fathers, as shown in previous studies. Reliability coefficients were high. In Study 2 (N = 1,171), we tested the relations between parental burnout and three specific consequences, i.e., escape and suicidal ideations, parental neglect, and parental violence toward one’s children. The medium to large associations found provided support for the PBA’s predictive validity. Overall, we concluded that the Spanish version of the PBA has good psychometric properties. The results support its relevance for the assessment of parental burnout among Spanish-speaking parents, offering new opportunities for cross-cultural research in the parenting domain.

Combined Longitudinal Study of the Second Generation in Spain data set, Waves 1, 2, and 3. This is the publicly available version of the ILSEG data (ILSEG is the Spanish acronym for Investigación Longitudinal de la Segunda Generación, Longitudinal Study of the Second Generation). Questions address the situations and plans for the future of young Spaniards who are children of immigrants to Spain, who were living in Madrid and Barcelona and attending secondary school in 2007-2008 and the 2011-2012 and 2015-2016 follow ups). The longitudinal study of the second Generation (ILSEG in its Spanish initials) represents the first attempt to conduct a large-scale study of the adaptation of children of immigrants to Spanish society over time. To that end, a large and statistically representative sample of children born to foreign parents in Spain or those brought at an early age to the country was identified and interviewed in metropolitan Madrid and Barcelona for wave 1. In total, almost 7,000 children of immigrants attending basic secondary school in close to 200 educational centers in both cities took part in the study. Because of sample attrition, wave 2 introduced a replacement sample. Additionally, a native born sample of children of Spaniards was also included to enable comparisons between native and immigrant-origin populations of the same age cohort.Topics include basic demographics, national origins, Spanish language acquisition, foreign language knowledge and retention, parents' education and employment, respondents' education and aspirations, religion, household arrangements, life experiences, and attitudes about Spanish society. Demographic variables include age, sex, birth country, language proficiency (Spanish and Catalan), language spoken in the home, number of siblings, mother's and father's birth country, religion, national identity, parent's sex, parent's marital status, parent's birth year, and the year the parent arrived in Spain.

In 2023, California had the highest Hispanic population in the United States, with over 15.76 million people claiming Hispanic heritage. Texas, Florida, New York, and Illinois rounded out the top five states for Hispanic residents in that year. History of Hispanic people Hispanic people are those whose heritage stems from a former Spanish colony. The Spanish Empire colonized most of Central and Latin America in the 15th century, which began when Christopher Columbus arrived in the Americas in 1492. The Spanish Empire expanded its territory throughout Central America and South America, but the colonization of the United States did not include the Northeastern part of the United States. Despite the number of Hispanic people living in the United States having increased, the median income of Hispanic households has fluctuated slightly since 1990. Hispanic population in the United States Hispanic people are the second-largest ethnic group in the United States, making Spanish the second most common language spoken in the country. In 2021, about one-fifth of Hispanic households in the United States made between 50,000 to 74,999 U.S. dollars. The unemployment rate of Hispanic Americans has fluctuated significantly since 1990, but has been on the decline since 2010, with the exception of 2020 and 2021, due to the impact of the coronavirus (COVID-19) pandemic.
