Psychometric validation of the Spanish version of the Dundee Ready Education Environment Measure applied to dental students.
2013
Aim: To carry out a psychometric evaluation of the Spanish-language version of the Dundee Ready Education Environment Measure (DREEM) applied to dental students. Methods: A total of 1,391 students from nine Spanish public schools of dentistry responded to the DREEM questionnaire. To analyse the reliability of the DREEM questionnaire, the internal consistency was assessed and a 'test-retest' carried out. Validity was evaluated through analysis of item response rate, floor and ceiling effects, corrected item-total and item-subscale correlations and factor structure. A confirmatory factor analysis was performed to analyse the structure of the original DREEM scale. Results: Cronbach's alpha coe…
The Serenity of the Meditating Mind: A Cross-Cultural Psychometric Study on a Two-Factor Higher Order Structure of Mindfulness, Its Effects, and Mech…
2014
Objective To investigate the psychometric and structural properties of the Five Facets Mindfulness Questionnaire (FFMQ) among meditators, to develop a short form, and to examine associations of mindfulness with mental health and the mechanisms of mindfulness. Methods Two independent samples were used, a German (n = 891) and a Spanish (n = 393) meditator sample, practicing various meditation styles. Structural and psychometric properties of the FFMQ were investigated with multigroup confirmatory factor analysis and exploratory structural equation modeling. Associations with mental health and mechanisms of mindfulness were examined with path analysis. Results The derived short form broadly ma…
Association between Actual and Perceived Motor Competence in School Children
2020
(1) Background: The association between actual and perceived motor competence (MC) is one of the underlying mechanisms that influence the practice of physical activity. This study mainly aimed to analyze the structure and correlations between actual and perceived MC in schoolchildren and to compare actual and perceived MC between girls and boys. (2) Methods: A total of 467 fifth and sixth graders (43.9% girls, M = 11.26, SD = 0.70) participated. Actual and perceived MC were assessed. To examine the proposed four factor models, structural equation models (factor analyses, latent correlations, invariance testing for gender) were conducted. Student t-test for independent samples was used to co…
Baseline Characteristics Predicting Very Good Outcome of Allogeneic Hematopoietic Cell Transplantation in Young Patients With High Cytogenetic Risk C…
2017
Patients with chronic lymphocytic leukemia with del(17p) or del(11q) have poor long-term prognosis with targeted therapies. Conversely, this retrospective European Society for Blood and Marrow Transplantation registry study shows that young high cytogenetic risk responsive patients with human leukocyte antigen-matched donors have a high 8-year progression-free survival and low 2-year non-relapse mortality after allogeneic stem cell transplantation. This treatment then may compare favorably with targeted therapies for younger high cytogenetic risk patients.Background: Patients with genetically high-risk relapsed/refractory chronic lymphocytic leukemia have shorter median progression-free sur…
Dimensional structure and measurement invariance of the BRIEF-2 across gender in a socially vulnerable sample of primary school-aged children.
2018
The present study aims to analyze, on the one hand, the dimensional structure of the BRIEF-2 and, on the other, its measurement invariance across gender in a sample of primary school-aged children. Participants were 168 students (51.8% girls) in conditions of social risk and in foster homes, with ages ranging from 6 to 15 years old (M = 10.08; SD = 2.09). The children's executive functioning level was obtained from their parents or caregivers. The analysis of the internal structure using confirmatory factor analysis reveals that the model with three indexes (Behavioral, Emotional and Cognitive) and nine scales (Inhibit, Shift, Self-Monitor, Emotional Control, Initiate, Working Memory, Plan/…
Development and Validation of a Scale to Measure Caregiver Skills in Eating Disorders
2015
Objective: The aim of this study was to develop and validate a new ques- tionnaire designed to measure caregiver skills that, in line with the interperso- nal component of the cognitive inter- personal maintenance model (Schmidt and Treasure, J Br J Clin Psychol, 45, 343–366, 2006), may be helpful in the support of people with anorexia nerv- osa (AN). A further aim is to assess whether this scale is sensitive to change following skills-based caregiver interventions. Method: The Caregiver Skills (CASK) scale was developed by a group of clinicians and caregivers. Preliminary versions of the scale devised for both caregivers and parents were given at baseline and at follow-up after two studies…
Psychometric properties of the structured Satisfaction Questionnaire with Gastrostomy Feeding (SAGA-8) for caregivers of children with gastrostomy tu…
2013
BACKGROUND: To analyse the psychometric properties of the structured Satisfaction Questionnaire with Gastrostomy Feeding (SAGA-8) in parents/caregivers of children with home enteral nutrition (HEN) by gastrostomy tube (GT). METHODS: Eighty-six caregivers (mothers) of paediatric patients with HEN by GT were recruited. Patients suffered from neurological disease (61.6%) and other chronic diseases. The SAGA-8 scale, a structured questionnaire to explore satisfaction with HEN by GT, and the Caregiver Burden Inventory (Zarit) were completed. The discriminating power of each of the SAGA-8 items, internal consistency and external validity were evaluated. An exploratory factor analysis and Kaiser-M…
Co-occurrence of developmental delays in a screening study of 4-year-old Finnish children
2004
The aim of this population study was to examine the severity and prevalence of co-occurring developmental delays in 4-year-old children, the rate of overlapping problems, and sex differences. A sample of 434 children (196 males, 238 females; mean age 4 years 3 months, SD 1 month) were administered the 'Lene' test: a comprehensive neurodevelopmental screening test. Results suggest that co-occurrence of attention-behavioural, motor-perceptual, and language delays occurring in school-aged children could already be detected at the age of 4 years. Isolated delays were usually mild, but co-occurring difficulties were mostly moderate or severe. Overlap between developmental delays depended on the …
Finnish pupils' perceptions of health education as a school subject.
2014
Only a few countries have introduced health education (HE) as a stand-alone school subject. In Finland every pupil in basic education grades 7–9 takes three obligatory courses in HE. This study investigated Finnish pupils’ perceptions of the teaching and learning of HE. It also explored how school- and family-related background variables are associated with these perceptions. Nationally representative data were obtained from a 2010 school-based study on Health Behaviour in School-aged Children (HBSC). A total of 4262 pupils from 7th and 9th grades (13 and 15 years old) responded anonymously to the questionnaire. Logistic regression analysis was performed to identify the associations betwee…
The convergent validity of four indices of congnitive complexity in person perception. A multi-index multimethod and factor analytical approach.
1975
.— An application of the Campbell and Fiske multimethod-multitrait analysis and factor analysis was used to study the convergent validity of the following indices of cognitive complexity: Bieri's Index, Vannoy's Interaction Variance Measure, Number of Factors, and First Factor Percentage. In the analysis the individual constructs elicited by Reptest were contrasted with two sets of provided constructs, namely Semantic Differential and Personality Differential scales. The subjects were 36 psychology students. The results indicated that the convergent validity of the indices over construct type was low and that the construct type had an effect upon the intercorrelations of different indices o…
