Cross-Cultural Validity of the Physical Self-Description Questionnaire: Comparison of Factor Structures in Australia, Spain, and Turkey
2002
Abstract We evaluated the cross-cultural generalizability of the factor structure for the Physical Self-Description Questionnaire (PSDQ) using confirmatory factor analysis. The factor structure was reasonably invariant over large samples of responses by Australian, Spanish, and Turkish students. Consistent with a priori predictions, the factor structures based on Australian and Spanish high school students were somewhat more similar to each other than to those based on Turkish university students, but these differences were small. Psychometric, theoretical, cross-cultural, and practical considerations support the PSDQ's usefulness in a variety of research and applied settings. The study als…
The generalizability of Older Adult Self-Report (OASR) syndromes of psychopathology across 20 societies
2020
Contains fulltext : 217516.pdf (Publisher’s version ) (Closed access) Objectives: As the world population ages, psychiatrists will increasingly need instruments for measuring constructs of psychopathology that are generalizable to diverse elders. The study tested whether syndromes of co-occurring problems derived from self-ratings of psychopathology by US elders would fit self-ratings by elders in 19 other societies. Methods/design: The Older Adult Self-Report (OASR) was completed by 12 826 adults who were 60 to 102 years old in 19 societies from North and South America, Asia, and Eastern, Northern, Southern, and Western Europe, plus the United States. Individual and multigroup confirmatory…
The Effects of Perceptions of Parents' Use of Social and Materials Rewards on Prosocial Behaviors in Spanish and U.S.Youth
2016
We examined the links between perceived parental use of social and material rewards and prosocial behaviors across youth from two countries. Six hundred forty adolescents (297 girls; [Formula: see text] age = 15.32 years) from Valencia, Spain, and 552 adolescents (321 girls; [Formula: see text] age = 13.38 years) from the United States completed measures of their perceptions of parental use of rewards, prosocial behaviors, and empathy. Results generally showed that perceived use of social rewards was directly and indirectly positively related to prosocial behaviors via empathic tendencies. In contrast, perceived use of material rewards was directly and indirectly negatively related to pros…
Aerobic fitness, but not physical activity, is associated with grey matter volume in adolescents.
2019
Higher levels of aerobic fitness and physical activity are linked to beneficial effects on brain health, especially in older adults. The generalizability of these earlier results to young individuals is not straightforward, because physiological responses (such as cardiovascular responses) to exercise may depend on age. Earlier studies have mostly focused on the effects of either physical activity or aerobic fitness on the brain. Yet, while physical activity indicates the amount of activity, aerobic fitness is an adaptive state or attribute that an individual has or achieves. Here, by measuring both physical activity and aerobic fitness in the same study, we aimed to differentiate the assoc…
Design, validation, and testing of an observational tool for technical and tactical analysis in the taekwondo competition at the 2016 Olympic games.
2020
Abstract Observational methodology uses validated observational tools to collect information in sports with multiple variables that interact in the sporting context. Given the importance of data quality for observational tools, the purpose of this study was to design, validate, and test the reliability of a mixed observational instrument combining field formats and category systems for analyzing technical and tactical actions in an Olympic taekwondo (TKD) tournament. The instrument collects information of six criteria and 25 categories of the tactical and technical actions, kicking zone, laterality, kicking leg, guard, and score. A total of 2 374 actions were analyzed from 10 bouts involvin…
The relationships between health anxiety, online health information seeking, and cyberchondria: Systematic review and meta-analysis
2018
© 2018 Background: Cyberchondria refers to an abnormal behavioral pattern in which excessive or repeated online searches for health-related information are distressing or anxiety-provoking. Health anxiety has been found to be associated with both online health information seeking and cyberchondria. The aims of the present systematic review and meta-analysis were to examine the magnitude of these associations and identify any moderator variables. Methods: A systematic literature search was performed across several databases (PsycINFO, PubMed, Embase) and reference lists of included studies. Results: Twenty studies were included across two independent meta-analyses, with 7373 participants. Ra…
Maternal and paternal psychological control and adolescents' negative adjustment: A dyadic longitudinal study in three countries.
2021
Psychological Control (PC) interferes with autonomy-related processes in adolescence and has a negative impact on adolescents’ development related to internalizing and externalizing problems. Several scholars suggested that PC can be used differently by mothers and fathers. However, these differences are still understudied and mainly grounded on maternal and/or adolescents’ perspectives, leading to potentially incomplete inferences on the effects of PC. The present study extends previous research on PC in two directions. First, we tested the dyadic and cumulative effects of maternal and paternal PC on adolescents’ antisocial behaviors and anxious-depressive symptoms. Secondly, we explored t…
Predicting critical illness on initial diagnosis of COVID-19 based on easily-obtained clinical variables: Development and validation of the PRIORITY …
2020
ABSTRACTObjectivesCurrently available COVID-19 prognostic models have focused on laboratory and radiological data obtained following admission. However, these tests are not available on initial assessment or in resource-limited settings. We aim to develop and validate a prediction model, based on clinical history and examination findings on initial diagnosis of COVID-19, to identify patients at risk of critical outcomes.MethodsWe used data from the SEMI-COVID-19 Registry, a nationwide multicenter cohort of consecutive patients hospitalized for COVID-19 from 132 centers in Spain. Clinical signs and symptoms, demographic variables, and medical history ascertained at hospital admission were sc…
We need more replication research – A case for test-retest reliability
2017
Following debates in psychology on the importance of replication research, we have also started to see pleas for a more prominent role for replication research in medical education. To enable replication research, it is of paramount importance to carefully study the reliability of the instruments we use. Cronbach’s alpha has been the most widely used estimator of reliability in the field of medical education, notably as some kind of quality label of test or questionnaire scores based on multiple items or of the reliability of assessment across exam stations. However, as this narrative review outlines, Cronbach’s alpha or alternative reliability statistics may complement but not replace psyc…
