The field of psychology prides itself on being a data-driven science.In 2008, however, Arnett brought to light major weakness in the evidence which models, measures, and theories rest.He demonstrated that most prominent journals six subdisciplines focused almost exclusively (over 70% samples authors) cultural context, United States, shared by only 5% world's population.How can psychologists trust these models results generalize all humans, if comes from small unrepresentative portion global...
Abstract Here, two studies seek to characterize a parsimonious common‐denominator personality structure with optimal cross‐cultural replicability. Personality differences are observed in all human populations and cultures, but lexicons for attributes contain so many distinctions that parsimony is lacking. Models stipulating the most important have been formulated by experts or empirical drawing on experience very limited range of cultures. Factor analyses nine languages diverse provenance (...
A general consensus on the Big Five model of personality attributes has been highly generative for field psychology. Many important psychological and life outcome correlates with trait dimensions have established. But researchers must choose between multiple inventories when conducting a study are faced variety options as to inventory length. Furthermore, 6-factor proposed extend update model, in part by adding dimension Honesty/Humility or Honesty/Propriety. In this study, 3 popular brief...
The Big Five is a useful model of attributes now commonly used in cross–cultural research, but without the support strong measurement invariance (MI) evidence. Six has been proposed as cross–culturally informed update, and broader Two (Social Self–Regulation Dynamism) draws on even more However, neither rigorously tested for MI. Here inventory (36QB6) measures derived from it were refined usability samples 26 nations, divided into three subsets. Confirmatory factor analysis models first...
We know that there are cross-cultural differences in psychological variables, such as individualism/collectivism. But it has not been clear which of these variables show relatively the greatest differences. The Survey World Views project operated from premise issues best addressed a diverse sampling countries representing majority world’s population, with very large range item-content. Data were collected online 8,883 individuals (almost entirely college students based on local publicizing...
Trait emotional intelligence (TEI) is emerging as a useful and promising individual difference in predicting vocational behavior (e.g., Di Fabio & Saklofske, 2014). Little yet known about the underlying processes that may lead TEI to associate with career related outcomes. This study investigates role of adaptability mediating association between decision-making difficulties self-perceived employability, sample Swiss university students (N = 400). The results series path analysis which we...
The field of psychology relies heavily on evidence from North America and Northern Europe.Universally-applicable models require input around the globe.Indigenous lexical studies personality, which define most salient person-descriptive concepts their structure in a population, provide this.Such results are reported two non-industrialized communities, representing three main language families Africa, groups with differing cultural characteristics.Maasai participants, traditionally herders...
Most personality science is conducted with samples from wealthy Western countries, home to only 11% of the world’s population. Longitudinal studies have been particularly informative for psychology, but they are virtually absent rest world. The Africa Long Life Study (ALLS) brings African perspectives lifespan research in and mental health. Large ( N = ∼1000), relatively-representative 18-year-olds were recruited throughout Namibia, Kenya, South 2022. Participants complete two surveys each...

Although grief is a universal part of the human experience, for some it may become debilitating mental health disorder. Prolonged disorder (PGD) has recently been included in diagnostic guidelines worldwide, but there little research on global applicability.

Over the last 20 years, personality development has become one of most widely studied topics in science. However, evidence on normative and event-related stems almost exclusively from Western countries, providing limited insight into cross-cultural generalizability trait changes. To address this limitation, we used data Africa Long Life Study to examine young adults Kenya, Namibia, South over 1 2 years (N = 2,382). We found that Big Two traits – Agency Communion were moderately rank-order...
It has been unclear which human-attribute concepts are most universal across languages. To identify common-denominator concepts, we used dictionaries for 12 mutually isolated languages-Maasai, Supyire Senoufo, Khoekhoe, Afar, Mara Chin, Hmong, Wik-Mungkan, Enga, Fijian, Inuktitut, Hopi, and Kuna-representing diverse cultural characteristics language families, from multiple continents. A composite list of every person-descriptive term in each lexicon was closely examined to determine the...
Personality is a broad concept used to organize the myriad ways that people differ psychologically from one another. There evidence such differences have been important humans everywhere, in personality-relevant terms appear all known languages. Empirical attempts identify most useful individual and their structure emphasized cross-cultural evidence, but rigid adherence Big Five model has sometimes meant ignoring heterogenous results. We start with framework for more precisely defining...
Psychology in Africa often relies on Euro-American theories, despite their limitations African cultures. Here, a shift to an Afrocentric perspective was made by exploring Ubuntu two sub-Saharan countries using cultural-developmental psychology approach for in-depth emic understanding. (also known as botho, etc.) is moral ideal that at core means placing higher importance the community than oneself. Most literature this important concept has been theoretical rather empirical, and little about...
What does it take to become an adult in Africa? Life-span-development literature includes little exploration on this transition outside Western countries. A qualitative approach was used identify locally relevant topics and variables understudied African context. Fifty 18- 25-year-old Ovambo Namibians from rural urban areas were interviewed. Results of reflexive thematic analysis suggest the significance gender birth order defining roles completion one’s education as a new rite passage. Full...
The Mental Health Parity and Addiction Equity Act (MHPAEA) significantly changed regulations governing behavioral health benefits for large, commercially insured employers. Pre-MHPAEA, many plans covered only a specific number of treatment days or visits; post-MHPAEA, such quantitative limits (QTLs) were allowed if they "at parity" with medical-surgical limits. This study assessed MHPAEA's effect on the prevalence QTLs.Analyses used 2008-2013 specialty benefit design data Optum large-group...
Objective Did mental health cost‐sharing decrease following implementation of the Mental Health Parity and Addiction Equity Act ( MHPAEA )? Data Source Specialty copayments, coinsurance, deductibles, 2008–2013, were obtained from benefits databases for “carve‐in” plans a national commercial managed behavioral organization. Study Design Bivariate regression‐adjusted analyses compare probability use (conditional) level pre‐ postparity. An interaction term is added to differential levels...
Personality psychology relies heavily on evidence from North America and Europe. Lexical studies, based the rationale that most important psychological distinctions between people will be encoded in natural languages, can provide input underrepresented contexts by defining locally relevant personality concepts their structure. We report results of a psycholexical study Khoekhoegowab, widely spoken southern Africa's (non-Bantu) click languages. It includes largest sample any lexical conducted...
Objective: The federal Mental Health Parity and Addiction Equity Act (MHPAEA) sought to eliminate historical disparities between insurance coverage for behavioral health (BH) treatment medical treatment. Our objective was evaluate MHPAEA’s impact on BH expenditures utilization among “carve-in” enrollees. Methods: We received specialty claims eligibility data from Optum, sampling 5,987,776 adults enrolled in self-insured plans large employers. An interrupted time series study design with...
Prediction of outcomes is an important way distinguishing, among personality models, the best from rest. Prominent previous models have tended to emphasize multiple internally consistent “facet” scales subordinate a few broad domains. But such organization measurement may not be optimal for prediction. Here, we compare predictive capacity and efficiency assessments across two types personality–structure model: conventional structures facets as found in platforms, new high–dimensionality...
