Children with differing developmental trajectories of prelinguistic communication skills: language and working memory at age 5.
2014
Purpose In this article, the authors examine the developmental continuity from prelinguistic communication to kindergarten age in language and working memory capacity. Method Following work outlining 6 groups of children with different trajectories of early communication development (ECD; Määttä, Laakso, Tolvanen, Ahonen, & Aro, 2012), the authors examined their later development by psychometric assessment. Ninety-one children first assessed at ages 12–21 months completed a battery of language and working memory tests at age 5;3 (years;months). Results Two of the ECD groups previously identified as being at risk for language difficulties continued to show weaker performance at follow-u…
The SF-8 Spanish Version for Health-Related Quality of Life Assessment: Psychometric Study with IRT and CFA Models.
2018
AbstractThe aim of current research is to analyze the psychometric properties of the Spanish version of the SF–8, overcoming previous shortcomings. A double line of analyses was used: competitivestructural equations modelsto establish factorial validity, andItem Response theoryto analyze item psychometric characteristics and information. 593 people aged 60 years or older, attending long life learning programs at the University were surveyed. Their age ranged from 60 to 92 years old. 67.6% were women. The survey included scales on personality dimensions, attitudes, perceptions, and behaviors related to aging. Competitive confirmatory models pointed out two-factors (physical and mental health…
The Use of a Screening Device to Assess Psychopathy in Young Offenders
2012
The aim of this research was to determine to what extent a psychopath screening device (the APSD) is useful in forensic assessments to predict general and violent offending. For this purpose, a cross-sectional study was done and 238 young people serving a sentence were assessed. The gold standard instrument used to measure psychopathy was the Psychopathy Checklist: Youth Version (PCL:YV; Forth, Kosson & Hare, 2003). The results indicate that the association found between the screening device scores and several indicators of risk is low if compared with those obtained with the PCL:YV, suggesting that it is less useful as a tool in order to predict offending or violent offences. However, …
Comprehension of metaphors and idioms in patients with Alzheimer's disease - A longitudinal study
2001
Language in patients with Alzheimer's disease has been extensively studied, with the exception of non-literal language comprehension. However, in our speech, we often make use of expressions, which are not necessarily interpreted on a literal ground. Comprehension of metaphors and idioms was examined in 39 patients with probable early Alzheimer's disease. The results showed that the decline of figurative language is not an early symptom of dementia and can occur independently from the impairment of propositional language. It was also found that metaphors and idioms differ as far as the predominant kind of error is concerned.
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 potential role of subjective wellbeing and gender in the relationship between bullying or cyberbullying and suicidal ideation
2018
Abstract Bullying and cyberbullying are common problems all over the world. One of their consequences can be suicidal ideation. A better understanding of the mechanisms that link them to suicidal ideation is needed in order to develop effective prevention and intervention initiatives. Subjective wellbeing is a potential mechanism that has not been studied within this framework. The present study examined whether subjective wellbeing could serve as a mediator or moderator of the relationship between bullying or cyberbullying and suicidal ideation, and whether these relationships were moderated by gender. Participants were 1664 students aged 14–19 (M = 16.12; SD = 1.36), 53% female, from 34 s…
Predictive Score Card in Lumbar Disc Herniation: Is It Reflective of Patient Surgical Success after Discectomy?
2016
Does the Finneson–Cooper score reflect the true value of predicting surgical success before discectomy? The aim of this study was to identify reliable predictors for surgical success two year after surgery for patients with LDH. Prospective analysis of 154 patients with LDH who underwent single-level lumbar discectomy was performed. Pre- and post-surgical success was assessed by the Oswestry Disability Index (ODI) over a 2-year period. The Finneson-Cooper score also was used for evaluation of the clinical results. Using the ODI, surgical success was defined as a 30% (or more) improvement on the ODI score from the baseline. The ODI was considered the gold standard in this study. Finally, the…
Identifying loci for the overlap between attention-deficit/hyperactivity disorder and autism spectrum disorder using a genome-wide QTL linkage approa…
2010
Contains fulltext : 88211.pdf (Publisher’s version ) (Closed access) OBJECTIVE: The genetic basis for autism spectrum disorder (ASD) symptoms in children with attention-deficit/hyperactivity disorder (ADHD) was addressed using a genome-wide linkage approach. METHOD: Participants of the International Multi-Center ADHD Genetics study comprising 1,143 probands with ADHD and 1,453 siblings were analyzed. The total and subscale scores of the Social Communication Questionnaire (SCQ) were used as quantitative traits for multipoint regression-based linkage analyses on 5,407 autosomal single-nucleotide polymorphisms applying MERLIN-regress software, both without and with inclusion of ADHD symptom sc…
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…
Floor and ceiling effects of the World Health Organization Disability Assessment Schedule 2.0 among patients with chronic musculoskeletal pain
2019
The aim of this study was to investigate the floor and ceiling effects of 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS). This was a cross-sectional survey study at a university’s physical and rehabilitation medicine outpatient clinic of 1988 patients with chronic musculoskeletal pain. Floor and ceiling effects were calculated as relative frequencies of the lowest or the highest possible scores for each item. The probit plotting method was used to detect the non-normality of distribution of the total score graphically. A significant floor effect of 15–79% was observed in all 12 WHODAS 2.0 items. A substantial floor effect for total score was also detected grap…
