    The characteristics associated with COVID-19-related dysfunctional grief suggest that we are most likely facing a “dysfunctional grief pandemic” due to COVID-19. Thus this preliminary study reports frequencies of dysfunctional grief in ten Latin American countries that varied between 7.3% in Brazil and 14.6% in El Salvador. This highlights a greater need for Latin American countries to work together to improve the accessibility of treatment for dysfunctional grief.

    The Purpose in Life Test (PIL) is a measure of purpose in life widely used in many cultures and countries; however, cross-cultural assessments are scarce. The present study aimed to evaluate the cross-cultural measurement invariance of the PIL in the general population of seven Latin American countries (Colombia, Ecuador, El Salvador, Mexico, Paraguay, Argentina, and Uruguay). A total of 4306 people participated, selected by non-probabilistic convenience sampling, where Uruguay has the highest mean age ( M = 41.8; SD = 16.6 years); while Ecuador has the lowest mean age ( M = 24.6; SD = 7.8 years). Furthermore, in each country, there is a higher proportion of women (>60%) than men (<40%). Using Multi-Group Confirmatory Factor Analysis, the factorial structure does not show evidence of invariance among the included countries. However, based on the Multi-Group Factor Analysis Alignment, there is evidence that a three-dimensional structure of the PIL (Meaning of existence, Freedom to make meaning in daily life and Will to find meaning in the face of future challenges) is the same in the participating countries. Results based on item response theory indicate that most PIL items can significantly differentiate responses according to the level of life purpose. In addition, people with low life purpose will tend to choose the lower response alternatives on the PIL; while people with higher life purpose will choose higher response alternatives. The findings indicate that the PIL has the potential to increase knowledge about how people conceive and experience their purpose in life in different countries.

    Sample size in quantitative instrument validation studies: A systematic review of articles published in Scopus, 2021
    (2022-12-01)
    BACKGROUND: Due to the range of conflicting criteria regarding minimum sample size needed for a scale/questionnaire validation study, the objective of this review is to analyze sample sizes used in published journal articles to contribute a pragmatic perspective to the discussion on sample sizes. METHODS: A sample of 1999 articles published in a Scopus-indexed journal about the validation of a scale or questionnaire during 2021 were analyzed for this study. Abstracts from these articles were tabulated by two data entry professionals and any discrepancies were reviewed by the author. The sample size data was grouped by highest quartile of the journal publishing the article and further sub-categorized based on the inclusion of medical patients or students in each study's population. RESULTS: From the total sample, 1750 articles provided sufficient information in their summary to determine the sample size used. Of these, the majority were published in quartile 1 (784) and quartile 2 (620) journals. Mean values by quartile ranged from 389 (quartile 3) to 2032 (quartile 1), but extreme outliers limited the usefulness of the simple mean. Thus, outlier-removed means were calculated, and in most cases, these sample size values were higher for studies involving students and lower for studies involving patients. DISCUSSION: This study is limited by its focus on a single database and by including all phases of validation from initial quantitative instrument design studies (which tend to have the lowest sample sizes) up to international macro-studies (which can have hundreds of thousands of participants.) Nevertheless, the results of this study provide an additional practical perspective for the academic discussion regarding minimum sample size based on accepted practice.

    BACKGROUND: There is an urgent need to assess changes in well-being on a multinational scale during the COVID-19 pandemic, thus culturally valid scales must be available. METHODS: With this in mind, this study examined the invariance of the WHO well-being index (WHO-5) among a sample of 5183 people from 12 Latin Americans countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay). RESULTS: The results of the present study indicate that the WHO-5 is strictly invariant across samples from different Latin American countries. Furthermore, the results of the IRT analysis indicate that all items of the WHO-5 were highly discriminative and that the difficulty required to respond to each of the five items is ascending. Additionally, the results indicated the presence of moderate and small size differences in subjective well-being among most countries. CONCLUSION: The WHO-5 is useful for assessing subjective well-being in 12 Latin American countries during the COVID-19 pandemic, since the differences between scores can be attributed to differences in well-being and not in other characteristics of the scale.

    Sample size in quantitative instrument-based studies published in Scopus up to 2022: An artificial intelligence aided systematic review
    (2023-11-01)
    Despite their popularity, quantitative instruments like Likert scales struggle with a practical issue for research projects - how many participants have to fill out the instrument? This study started with the data for 31,271 articles downloaded from Scopus and, after exclusions, reviewed the sample size used in 21,506 studies. Scimago highest quartile data was brought in for 1999-2021 and linked to the exported articles. Anthropic's Claude and Claude-Instant AI tools were used to analyze the journal article abstracts and extract the sample size information. Frequency distribution of sample size used are presented. Descriptive statistics such as maximum, average and trimmed averaged sample size values are presented by quartile of the journal where the article was published, range of years when the article was published, 3 common analyses which tend to increase sample size, and two population groups which have been shown to impact sample size. The study concludes with ranges for commonly used sample sizes based on a number of criteria. This is one of the first studies to use AI tools to assist in the analysis for a systematic review study.
