Perception of quality of life in an elderly Angolan sample / Percepción de calidad de vida en una muestra de ancianos angoleños
2014
AbstractIncreased life expectancy and the ageing of the population have made it particularly important to distinguish between the old (usually 60–79 years, or the ‘young old’) and the oldest old (80 years or more, or the ‘fourth age’). This study explores the effects of age, gender and institutionalization on perceived health and life satisfaction in 1003 elderly people from Luanda, Angola. A multivariate analysis of variance (MANOVA) was estimated to test for these effects. Results provide evidence of lower scores on life satisfaction and perceived health for the oldest old and the institutionalized. However, the higher life satisfaction among the non-institutionalized disappeared when the…
Modeling soil cation exchange capacity in multiple countries
2017
Abstract Cation exchange capacity (CEC), as an important indicator for soil quality, represents soil's ability to hold positively charged ions. We attempted to predict CEC using different statistical methods including monotone analysis of variance (MONANOVA), artificial neural networks (ANNs), principal components regressions (PCR), and particle swarm optimization (PSO) in order to compare the utility of these approaches and identify the best predictor. We analyzed 170 soil samples from four different nations (USA, Spain, Iran and Iraq) under three land uses (agriculture, pasture, and forest). Seventy percent of the samples (120 samples) were selected as the calibration set and the remainin…
Emotion regulation strategies in relation to personality characteristics indicating low and high self-control of emotions
1999
Abstract The study was part of the Jyvaskyla Longitudinal Study of Personality and Social Development, in which children's (196 boys, 173 girls) behavioral characteristics indicating the self-control of emotions were studied at age 8 using teacher ratings. At age 36, 140 men and 128 women filled in several inventories, including the Meta-Regulation Scale [Mayer, J. D., & Stevens, A. A. (1994). An emerging understanding of the reflective (meta-)experience of mood. Journal of Research in Personality , 28 , 351–373] and the Karolinska Scales of Personality [Af Klinteberg, B., Schalling, D., & Magnusson, D. (1986).

An undergraduate thesis training course for faculty reduces variability in student evaluations
2020
Abstract Background The undergraduate thesis evaluation process is one of the most prevalent weak points in universities; the literature indicates the need to orient undergraduate thesis evaluators through specific training initiatives. Objectives The aim of this study was to analyze the discrepancies between the grades awarded by undergraduate thesis supervisors and by the panel of faculty examiners, and the effect of training targeted to faculty members. Design and methods A cross-sectional study was performed during the 2015–2016 academic year in a Spanish Nursing School. Settings and participants We analyzed the mean grades from undergraduate thesis evaluation rubrics and the effects of…
Applying a web-based training to foster self-regulated learning — Effects of an intervention for large numbers of participants
2016
Trainings on self-regulated learning (SRL) have been shown to be effective in improving both competence of self-regulated learning and objective measures of performance. However, human trainers can reach only a limited number of people at a time. Web-based trainings (WBT) could improve efficiency, as they can be distributed to potentially unlimited numbers of participants. We developed a WBT based on the process model of SRL by Schmitz and Wiese (2006) and tested it with 211 university students in a randomized control evaluation study including additional process analyses of learning diaries. Results showed that the training had significant effects on SRL knowledge, SRL behavior measured by…
Multivariate nonparametric tests in a randomized complete block design
2003
AbstractIn this paper multivariate extensions of the Friedman and Page tests for the comparison of several treatments are introduced. Related unadjusted and adjusted treatment effect estimates for the multivariate response variable are also found and their properties discussed. The test statistics and estimates are analogous to the traditional univariate methods. In test constructions, the univariate ranks are replaced by multivariate spatial ranks (J. Nonparam. Statist. 5 (1995) 201). Asymptotic theory is developed to provide approximations for the limiting distributions of the test statistics and estimates. Limiting efficiencies of the tests and treatment effect estimates are found in the…
Efecto moderador de la institucionalización en las actividades de la vida diaria y bienestar en el envejecimiento
2012
OBJETIVO: El envejecimiento con éxito es un concepto multidimensional que se puede evaluar a partir de componentes objetivos y subjetivos como el funcionamiento físico, psicológico y social. El objetivo de este trabajo es comparar el funcionamiento en variables relacionadas con el envejecimiento exitoso en ancianos institucionalizados y no institucionalizados. MÉTODO: Se realizó un diseño de dos grupos independientes, institucionalizados (N=242) y no institucionalizados (N=607), todos de más de 65 años, evaluándose sus actividades de la vida diaria (AVD) y el bienestar psicológico. RESULTADOS: El Índice de Barthel mostró diferencias significativas, siendo inferior la media de los institucio…
Resilience as a predictor of Quality of Life in participants with borderline personality disorder before and after treatment.
2021
Abstract Background Studies have suggested that psychotherapy improves the Quality of Life (QoL) of participants with Borderline Personality Disorder (BPD). However, there are no studies on the differential efficacy of treatments on the QoL of participants with BPD. Moreover, the relationship between QoL and resilience has rarely been studied in participants with BPD. Objectives: a) to examine whether people with BPD have worse QoL than the non-clinical population; b) to examine whether there are statistically significant differences between Dialectical Behavioural Therapy (DBT), Systems Training for Emotional Predictability and Problem Solving (STEPPS), or Cognitive Behavioural Therapy-Tre…
Effectiveness of a mobile app intervention to prevent dating violence in residential child care
2020
ABSTRACT This study focuses on the effectiveness of an app-based, monitored intervention using the Liad@s app in a residential youth-care setting. The aim of this intervention is to reduce maladaptive beliefs and attitudes linked to dating violence: distortions or myths about romantic love and hostile and benevolent dimensions of sexism. A quasi-experimental pre-post study with a control group was carried out. Participants were 71 adolescents from 9 group homes in Valencia (Spain). The outcomes measures were hostile and benevolent sexism (Ambivalent Sexism Inventory - ASI), ambivalence and prejudice towards men (Ambivalence toward Men Inventory - AMI), and myths about romantic love. The res…
