Suicidal ideation in a community-derived sample of Spanish adolescents
2017
Introduction: Suicide is a current public health problem and among the main causes of mortality in adolescents and young adults. The main goal of this study was to analyse suicidal ideation in a representative sample of Spanish adolescents. Specifically, the prevalence rates of suicide ideation, the psychometric properties of the Paykel Suicide Scale (PSS) scores, and the socio-emotional adjustment of adolescents at risk for suicide were analysed. Material and methods: The sample consisted of 1,664 participants (M = 16.12 years, SD = 1.36, range 14-19 years), selected by stratified sampling by clusters. The instruments used were the PSS, the Strengths and Difficulties Questionnaire, the Per…
Children's brain responses to sound changes in pseudo words in a multifeature paradigm.
2011
Abstract Objective The multifeature mismatch negativity (MMN) paradigm has previously been used to study MMN responses to changes in tones or isolated syllables. We tested 4–12year old children's MMNs to changes in a naturally produced pseudo word context. Methods We studied preschoolers' (under the age of 7years, N =15, mean age 5years 4months) and school childrens' (over the age of 7years, N =15, mean age 9years 3months) MMNs to five types of changes (vowel duration, fundamental frequency, gap, intensity, vowel identity) in the middle syllable of a pseudo word [tɑtɑtɑ] using a multifeature paradigm. Results Vowel duration and gap changes elicited larger frontocentral MMN responses than ot…
Emotional eating scale for children and adolescents: psychometric characteristics in a Spanish sample
2011
The aims of this study were to validate the Emotional Eating Scale version for children (EES-C) in a Spanish population and study the differences in emotional eating among children with binge eating (BE), overeating (OE), and no episodes of disordered eating (NED). The questionnaire was completed by 199 children aged 9 to 16 years. Confirmatory factor analysis revealed five scales: eating in response to anger, anxiety, restlessness, helplessness, and depression. The EES-C showed good internal consistency and test-retest reliability, and it showed moderate relationships with measures of disordered-eating [Children's Eating Attitudes Test-26 (ChEAT-26), Questionnaire of Eating and Weight Patt…
Demoralization Scale in Spanish-Speaking Palliative Care Patients.
2015
Abstract Context Among the approaches to the demoralization syndrome, the one proposed by Kissane et al. is prevalent in the literature. These authors developed the Demoralization Scale (DS) to assess emotional distress, conceived as demoralization. Objectives To present the Spanish adaptation of the Demoralization Scale in palliative care patients, with a new and more comprehensive approach to its factorial structure. Methods A cross-sectional study was carried out in 226 Spanish palliative care patients in three different settings: hospital, home care unit, and continued care unit. Outcome measures included the DS and the Hospital Anxiety and Depression Scale. Analyses comprised confirmat…
The role of fear-avoidance cognitions and behaviors in patients with chronic tinnitus.
2012
The current study investigated the role of fear-avoidance-a concept from chronic pain research-in chronic tinnitus. A self-report measure the "Tinnitus Fear-Avoidance Cognitions and Behaviors Scale (T-FAS)" was developed and validated. Furthermore, the role of fear-avoidance behavior as mediator of the relationship between anxiety sensitivity and tinnitus handicap was investigated. From a clinical setting, N = 373 patients with chronic tinnitus completed questionnaires assessing tinnitus handicap (Tinnitus Handicap Inventory), anxiety, depression (Hospital Anxiety and Depression Scale), anxiety sensitivity (Anxiety Sensitivity Index-3), personality factors (Big Five Inventory-10), and fear-…
Psychometric Analysis of the Selective Reminding Procedure in a Sample from the General Elderly Population
2000
The selective reminding procedure (SRP) has been proposed for the assessment of distinct aspects of episodic memory, i.e. storage to and retrieval from short-term and long-term memory, item learning and list learning, and as dementia screening tool. In the present study SRP results were analysed in 256 probands from the general elderly population. SRP scores were highly intercorrelated, and principal component analysis yielded only one single factor. The SRP scores were moderately and not differentially correlated with immediate and delayed free recall and recognition and with verbal fluency. All SRP scores discriminated nondemented probands with episodic long-term memory impairment from th…
RHINASTHMA-Children: A new quality of life tool for patients with respiratory allergy
2017
Background Specific instruments for health-related quality of life (HRQoL) assessment in adolescents with rhinoconjunctivitis or asthma are available. None of them evaluates rhinitis and asthma together, although they often coexist. Our aim was to validate a HRQoL questionnaire for adolescents with rhinoconjunctivitis, asthma, or both. Methods A pool of 38 items covering the main symptoms and problems related to respiratory allergy was generated based on literature review, clinical experience, and unstructured interviews to 54 adolescents. The items were randomly listed and presented to 88 consecutive outpatients (44 M; mean age 15.2 ± 3.1). Patients had to indicate which item they had expe…
Psychometric properties of the updated EORTC module for assessing quality of life in patients with lung cancer (QLQ-LC29): an international, observat…
2020
Abstract: Background The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) assesses quality of life (QOL) in patients with lung cancer and was the first EORTC module developed for use in international clinical trials. Since its publication in 1994, major treatment advances with possible effects on QOL have occurred. These changes called for an update of the module and its international psychometric validation. We aimed to investigate the scale structure and psychometric properties of the updated lung cancer module, QLQ-LC29, in patients with lung cancer. Methods This international, observational field study was done in…
Temporal abnormalities in children with developmental dyscalculia.
2012
Recent imaging studies have associated Developmental dyscalculia (DD) to structural and functional alterations corresponding Parietal and the Prefrontal cortex (PFC). Since these areas were shown also to be involved in timing abilities, we hypothesized that time processing is abnormal in DD. We compared time processing abilities between 10 children with pure DD (8 years old) and 11 age-matched healthy children. Results show that the DD group underestimated duration of a sub-second scale when asked to perform a time comparison task. The timing abnormality observed in our DD participants is consistent with evidence of a shared fronto-parietal neural network for representing time and quantity.…
Structural validity of the Finnish Manchester-Oxford Foot Questionnaire (MOXFQ) using the Rasch model.
2019
Background: The 16-item patient-reported Manchester-Oxford Foot Questionnaire (MOXFQ) with subscales of pain, social interactions, and walking/standing has been claimed for strongest scientific evidence in measuring foot and ankle complaints. This study tests the validity of the Finnish MOXFQ for orthopaedic foot and ankle population using the Rasch analysis. Methods: We translated the MOXFQ into Finnish and used that translation in our study. MOXFQ scores were obtained from 183 patients. Response category distribution, item fit, coverage, targeting, item dependency, ability to measure latent trait (unidimensionality), internal consistency (Cronbach's alpha), and person separation index (PS…
