Epidemiology of eating disorders in Latin America: a systematic review and meta-analysis.
2016
Purpose of reviewEating disorders are currently not considered to be limited to Western culture. We systematically reviewed the existing literature on the prevalence of eating disorders in Latin America.Recent findingsOf 1583 records screened, 17 studies from Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela were included in the analysis. Most studies reported point-prevalence rates and only three studies provided lifetime and 12-month prevalence rates. We found a mean point-prevalence rate of 0.1% for anorexia nervosa, 1.16% for bulimia nervosa, and 3.53% for binge-eating disorder (BED) in the general population. Heterogeneity for bulimia nervosa and BED was large. This meta-analys…
Using the Johnson-Neyman Procedure to Detect Item Bias in Personality Tests
2016
I present an alternative to a widely used item-bias analysis procedure known as the ANOVA method. The new method is based on the Johnson-Neyman procedure, which is a multiple regression-based technique with properties that can overcome the major weaknesses of the ANOVA method. I introduce the proposed procedure in a non-technical manner, provide an illustrative example, and suggest guidelines for empirical analysis that can be readily applied in personality research.
Experimental lung injury induces cerebral cytokine mRNA production in pigs
2020
Background Acute respiratory distress syndrome (ARDS) is an important disease with a high incidence among patients admitted to intensive care units. Over the last decades, the survival of critically ill patients has improved; however, cognitive deficits are among the long-term sequelae. We hypothesize that acute lung injury leads to upregulation of cerebral cytokine synthesis. Methods After approval of the institutional and animal care committee, 20 male pigs were randomized to one of three groups: (1) Lung injury by oleic acid injection (OAI), (2) ventilation only (CTR) or (3) untreated. We compared neuronal numbers, proportion of neurons with markers for apoptosis, activation state of Ib…
ATRIAL FIBRILLATION AND MILD COGNITIVE IMPAIRMENT: WHAT CORRELATION?
2006
ATRIAL FIBRILLATION AND MILD COGNITIVE IMPAIRMENT: WHAT CORRELATION? Aim. Atrial fibrillation (AF), in addition to macroembolic complications, may also produce multiple cerebral ischemic areas due to microembolic phenomena and transient hypoperfusion, eventually leading to a progressive cognitive impairment and even to acclaimed vascular dementia. The aim of this study was to evaluate the prevalence of cognitive impairment in patients with AF. The reported results concern data obtained at the moment of recruitment. Methods. The authors studied 42 patients with a history of non valvular AF (paroxysmal, persistent, recurrent or permanent) and 40 homogenous controls in sinus rhythm without pre…
EMBEDDING CONTEXT IN INVESTIGATIONS OF AFFECTIVE VARIABILITY: AGE DIFFERENCES IN AFFECT-HEALTH LINKS
2017
Context plays a potentially important role in explaining variability in affective experiences and yet, has often been overlooked in this line of research. The current study used data from a lifespan sample of 398 German participants ranging between 12–88 years of age (M = 40, SD = 20). Participants completed computer assisted personal interviews regarding health and well-being measures, as well as experience sampling assessments of daily affective experiences and events (e.g., uplifts). Three indices of positive affect (PA) were created: mean PA, PA reactivity to uplifts, and PA variability. In general, greater mean PA and lower PA reactivity and variability were associated with better heal…
FLEXIBLE AND TENACIOUS GOAL PURSUIT IN RELATION TO OUTDOOR MOBILITY IN OLD AGE
2018
Goal pursuit may affect older people’s outdoor mobility, a correlate of quality of life. This study investigated associations of flexible and tenacious goal pursuit with perceived autonomy in participation outdoors and life-space mobility. Participants were community-dwelling older people aged 79–93 years (n=185). Tenacious goal pursuit (TGP) and flexible goal adjustment (FGA) were self-reported with separate scales (ranges 5–25). Perceived autonomy in participation was assessed with the Impact on Participation and Autonomy ‘outdoors’-subscale (range 0–20), and life-space mobility with the Life-Space Assessment (range 0–120). Two-step cluster analysis was used to create data-driven goal pur…
Substance Use in Early and Middle Adolescence. The Role of Academic Efficacy and Parenting
2019
espanolLos objetivos de esta investigacion son analizar la relacion del consumo de sustancias con el estilo de crianza de los padres y la percepcion de eficacia academica por parte de los adolescentes, estudiar la diferente contribucion de estos factores a la prediccion del consumo de sustancias en la adolescencia y observar la funcion de la autoeficacia academica en la relacion entre el estilo de crianza y el consumo de sustancias en la adolescencia. Participaron 762 adolescentes (53% hombres), de edades comprendidas entre los 12 y los 16 anos (M = 13.66, DT = 1.34). La muestra se selecciono con criterios probabilisticos por conglomerados, atendiendo al tipo de centro (educacion secundaria…
Teachers’ Perceptions of Relationship Enhancement Upon Implementation of the Social Emotional Learning Program in Latvia: Focus Group Study
2017
The goal of this study was to elicit and analyse teachers’ reflections on the benefits of the implementation of the SEL program in Latvia, both in regard to benefits for the students and in regard to benefits for themselves. The school-wide Latvia SEL program was initiated during the 2012–13 academic year and to date has been implemented in 41 Latvian schools. In order to ascertain the teachers’ views on issues of program effectiveness, seven focus groups were organised consisting of teachers who had participated in the SEL program implementation. Thematic analysis of the focus group discussions indicated that the teachers appreciate various benefits of the SEL program, but among the most p…
Adaptation and Validation of the Spanish Version of the Instrument to Evaluate Nurses’ Attitudes Toward Communication With the Patient for Nursing St…
2021
Communication is essential to quality of care and patient satisfaction. It has been linked to positive patient outcomes, increased engagement, improved health outcomes and safe practices. Given these benefits and the association between attitudes and behaviours, as behaviours can be predicted by studying attitudes, assessing nursing students' attitudes toward patient communication is critical as future nursing professionals. For this purpose, the main aim of this study was to adapt and validate an instrument to measure nurses´ attitudes towards communication (ACO) for nursing students. The attitudes towards communication with patients were analyzed. Then, differences in the dimensions of th…
Tratamiento crítico de la información de estudiantes universitarios desde los entornos personales de aprendizaje
2019
Resumen Partiendo del Proyecto CAPPLE (financiado por el Ministerio español de Economía y Competitividad), en este artículo identificamos las estrategias y las herramientas en red utilizadas por 2054 estudiantes universitarios españoles de último curso para efectuar un tratamiento crítico de la información y gestionar su proceso de aprendizaje. Desde un diseño de investigación no experimental de tipo exploratorio, se ha utilizado un cuestionario validado a través de un triple procedimiento (juicio de expertos, entrevistas cognitivas y estudio piloto) para recoger datos de 75 universidades en España. Los resultados muestran que los futuros profesionales son conscientes de la necesidad de con…
