Parental Affection and Psychological Control as Mediators Between Parents’ Depressive Symptoms and Child Distress
2013
The present study investigated the extent to which parental behavior in daily interaction with one’s child mediates the associations between parental depressive symptoms and children’s daily distress. The participants were 152 Finnish families with a 6- to 7-year-old child. Parents’ depressive symptoms were assessed using the revised Beck Depression Inventory. Children’s distress was operationalized as negative daily emotions assessed by using mother-, father-, and teacher-reported diary questionnaires. Parental affection and psychological control in daily interaction were measured using parent self-reported diary questionnaires. The results of structural equation modeling showed that both…
Transcultural Adaptation and Theoretical Models of Validation of the Spanish Version of the Self-Care of Heart Failure Index Version 6.2 (SCHFI v.6.2)
2021
Background: Heart failure (HF) is a major and growing public health problem worldwide. Across the world, heart failure is associated with high mortality, high hospitalization rates, and poor quality of life. Self-care is defined as a naturalistic decision-making process involving the choice of behaviors that maintain physiologic stability, the response to symptoms when they occur, and the ability to follow the treatment regimen and control symptoms. One instrument used to measure self-care is the Self Care of Heart Failure Index. Aim: The purpose of this study was to test the psychometric properties of the Spanish version of the Self Care of Heart Failure Index v.6.2 (SCHFI v.6.2). Methodol…
The Fear of Covid-19 Scale (FCV-19S) in Spain: Adaptation and Confirmatory Evidence of Construct and Concurrent Validity
2021
Fear of the coronavirus has important implications on mental health. In western countries, a significant degree of vaccination has been achieved, but in Spain, less than 75% of the population has received both doses. The current situation is still seen as a threat by many people. Therefore, it is important to have reliable and valid measurement instruments to assess the impact of COVID-19 on the population. In this study, the Fear of COVID-19 Scale has been adapted to Spain, and its psychometric properties have been studied in a Spanish sample using Structural Equation Modeling. This methodology allows obtaining more reliable estimates, regardless of the measurement scale of the variables. …
Psychometric Evaluation of the Norwegian Versions of the Modified Group Environment Questionnaire and the Youth Sport Environment Questionnaire
2021
This study aimed to translate the modified Group Environment Questionnaire (GEQ) and the Youth Sport Environment Questionnaire (YSEQ) into Norwegian, examine the factor structure and reliability of the scales through independent clusters model confirmatory factor analysis (ICM-CFA) and exploratory structural equation modeling (ESEM), and examine differential item functioning (DIF) as a function of sex. Three-hundred-and-thirty-three athletes (M(SD)age = 18.7(2.60) years; 33% females) completed the GEQ. Three-hundred-and-three athletes (M(SD)age = 15.0(1.48) years; 26% females) completed the YSEQ. Results indicated acceptable fit indices for a four-factor, a second-order two-factor (task a…
Facing the music : a critical enquiry into 'the dodo-bird verdict' to develop music psychotherapy theory
2015
‘The dodo-bird verdict’ represents a boggling outcome of research that shows no significant difference between the outcomes of a variety of psychotherapy treatments. Not being able to scientifically discriminate between psychotherapeutic treatments, casts doubt on their theoretical underpinnings, and even on their efficacy. This in turn presents professionals who use psychotherapeutic techniques - including music therapists - with a conundrum: What can explain this inability? And what can be done to solve the problem? Conceptual research methods were used to analyse literature in order to answer these questions. Various weaknesses were identified, both in theory construction and in research…
Effects of training on bone metabolism in young athletes
2021
Purpose. This study investigated the effects of two types of training on the bone formation marker of osteocalcin and the bone resorption marker of tartrate-resistant acid phosphatase isoenzyme 5b (TRAP5b) in young track and field boys and girls. Methods. The 14-year-old group (10 boys, 10 girls) performed first time an intensive and supervised 8-week plyometric training. In the 17-year-old group (13 athletic boys, 6 control boys, 12 athletic girls, 6 control girls), the normal many-sided track and field training lasted 6 months. Results. Significant increases were noticed in osteocalcin (p < 0.01) both in younger boys and girls. The 20-m sprint performance improved in girls (p < 0.01) and …
A control strategy based on intelligent algorithm (PSO) to perform electrical stimulation systems
2017
International audience; Adjusting stimulation parameters using control strategy based on reliable mathematical model that can predict perfectly the muscle response, may improve the efficiency of Functional Electrical Stimulation (FES) systems. In the present project, we investigate the PID control tuning based on the Particle Swarm Optimization (PSO) algorithm at the first time in neuro-muscular systems for updating automatically the stimulation pulse amplitude to track a desired force profiles. In the beginning, The PSO algorithm is used to identify unknown force model parameters. Next, optimal PID gains are found by the same intelligent algorithm to improve the control system. The obtaine…
Estudio de validación de pulsioximetría como método diagnóstico no invasivo de atelectasias tras anestesia general
2017
Introducción. Las complicaciones pulmonares postoperatorias son una entidad muy frecuente tras una anestesia general, llegando a diagnosticarse hasta en el 20 % de los pacientes. Sin embargo, se piensa que este porcentaje está infraestimado debido a que se requieren técnicas de imagen para el diagnóstico y el uso de fracciones inspiratorias de oxígeno altas. Estas complicaciones, en concreto las atelectasias, disminuyen la presión arterial de oxígeno causando hipoxemia. Esto conlleva un aumento de la morbimortalidad de los pacientes, pudiendo reagudizar las patologías de base y favoreciendo la aparición de otras complicaciones. Por ello, es necesario determinar un método de diagnóstico senc…
Like ships passing in the night? Nonstandard work schedules and spousal satisfaction in Finland, the Netherlands and the United Kingdom
2020
This study examined the associations of work schedules and spousal satisfaction among Finnish (n = 347), Dutch (n = 304) and British (n = 337) parents. In addition to comparing parents with nonstandard schedule with parents in regular day work, the study examined separately the roles played in spousal satisfaction of morning, evening, night and weekend work and other working time-related variables (working hours, changes in and influence over one’s work schedules and spouse’s work schedule). The three-country data were analyzed using structural equation modeling with a multigroup procedure in Mplus. Little evidence for negative associations of work schedules and related factors with spousal…
