Psychometric performance of the social networks addiction risk questionnaire (Cars‐R)
Cross-national invariance of the Spanish version of the 8-item Posttraumatic Growth Inventory-Short Form (PTGI-SF) in people who experienced the death of loved ones from four South American countries
Post-pandemic, there is concern about the increase in mental health problems associated with grief due to COVID-19. Recent studies have identified positive outcomes that may have emerged in the face of adversity, which can lead to positive psychological changes, such as posttraumatic growth. The aim of the study was to evaluate the transnational measurement invariance of the 8-item Posttraumatic Growth Inventory-Short Form (PTGI-SF) in individual…
Short Version of the Social Networks Addiction Risk Questionnaire (Cars-R)
Recent scientific literature shows evidence that social media addiction negatively impacts people's mental health. In this sense, network models offer a methodological framework that naturally allows the study of mental health disorders' complexity. Therefore, the study aims to study the psychometric properties of CARS-R from the perspective of psychometric networks. A sample of 1,719 adults of both sexes (38.3% men and 61.7% women) between the a…

The present study aimed to apply a network analysis model to provide an exploratory empirical conceptualization of dynamic networks of posttraumatic growth (PTG) symptoms in 7,434 people who experienced the death of a loved one from COVID-19 in 16 Latin American countries. The Post-Traumatic Growth Inventory: Short Form of Eight Items was used. A non-regularized network with partial correlation coefficients was estimated through the ggmModSelect …
Cross-Cultural Validity of the Grief Impairment Scale (GIS)
The Grief Impairment Scale (GIS) is used to measure functional impairment due to grief following the death of a loved one. However, there is no information on its cross-cultural utility. Thus, this study assessed the measurement invariance of the GIS using a large sample of bereaved adults ( N = 2060) from Peru, El Salvador, Ecuador, and Colombia. Specifically, we employed two measurement invariance techniques: multi-group confirmatory factor ana…

The results indicate that the GIS items were grouped into a single network structure through Exploratory Graph Analysis. Reliability was es…
Can a global score be derived from the Integration of Stressful Life Experiences Scale-Short Form (Isles-SF)? Empirical support for a bi-factor model
The Integration of Stressful Life Experiences Scale-Short Form (ISLES-SF) is a popular, two-factor measure of meaning-making. Although researchers have used this instrument to calculate a global index of meaning-making, there has been little evidence to support this practice. Therefore, the objective of this study was to examine the validity of this approach by analyzing data from 2,380 American adults during the beginning of the COVID-19 pandemi…
Family functioning in students of health sciences in four Latin American countries
BACKGROUND: Psychometric studies of the FACES III scale in Spanish-speaking countries show a lack of agreement on the factorial structure of the scale.

The current study aims to evaluate the internal structure and factorial invariance of the SWLFS in adolescents from Peru …
Design and Cross-Cultural Invariance of the Covid-19 Vaccine Conspiracy Beliefs Scale (Covid-VCBS) in 13 Latin American Countries
Aims: Over the past 2 years, the vaccine conspiracy beliefs construct has been used in a number of different studies. These publications have assessed the determinants and outcomes of vaccine conspiracy beliefs using, in some cases, pooled data from different countries, and compared the results across these contexts. However, studies often do not consider measurement invariance as a necessary requirement for comparative analyses. Therefore, the a…
