Rasch analysis of the Lower Extremity Functional Scale for foot and ankle patients.
2018
Purpose: The Lower Extremity Functional Scale (LEFS) is a widely used 20-item patient-reported outcome instrument with five response categories. We investigated the measurement properties of the Finnish version of the LEFS among foot and ankle patients to refine the scale to measure more accurately what is relevant for patients.Materials and methods: Data were obtained from 182 patients who had undergone foot and ankle surgery for various reasons. The Rasch Measurement Theory and Cronbach's alpha were employed for analyses of model and item fit, response category thresholds, targeting, person separation index, and internal consistency.Results: Threshold misfit was noted in 13 of the 20 item…
Psychometric properties of the Spanish version of the involvement evaluation questionnaire in caregivers of patients with borderline personality diso…
2018
The involvement evaluation questionnaire (IEQ) was created to evaluate the caregiver's experience of burden and the consequences of providing care to people with psychotic disorders. To date, the IEQ has not been validated with caregivers of people diagnosed with borderline personality disorder (BPD). The main objective of the study was to confirm the psychometric properties and factorial structure of the Spanish version of the IEQ in 151 caregivers of people with BPD, with an average age of 54.52 (SD = 9.91). Two models were tested by means of confirmatory factor analysis, following the original factor structure. The Models 1 and 2 displayed adequate fit, with comparative fit index and Tuc…
Use of the Perceived Physical Competence Scale with Adolescents with Disabilities
1995
The construct validity and reliability of the 1987 Perceived Physical Competence Scale of Lintunen were examined to assess the applicability of the instrument for use with adolescents with disabilities. Subjects were 51 girls and 34 boys ( M age = 15.1 yr.) from several schools in central Finland. Principal component factor analysis with varimax rotation yielded the same two factors for adolescents with disabilities as reported for nondisabled adolescents in the related literature. Cronbach alphas for the two factors were .89 and .56. It was concluded that the scale is an appropriate measure for adolescents with disabilities. Statistical analysis indicated no gender differences for adolesc…
Children's eating attitudes test: Validation in a sample of Spanish schoolchildren
2010
Objective: To validate the Spanish version of the Children's Eating Attitudes Test (ChEAT). Method: The factor structure and other psychometric characteristics of the questionnaire were examined using the answers of 38,554 schoolchildren. Diagnostic efficiency was based on a standardized clinical interview of 968 schoolchildren who had previously completed the questionnaire. Results: Five factors (“preoccupation with thinness,” “dieting,” “social pressure to eat,” “purging,” and “preoccupation with food and oral control”) explained 46% of the variance. Cronbach's α was .858 for the total scale. The area under the receiver operating characteristic curve was .851. Sensitivity (SE) was 27% and…
Development and Validation of the ADAS Scale and Prediction of Attitudes Toward Affective-Sexual Diversity Among Spanish Secondary Students
2017
Violence against non-heterosexual adolescents in educational contexts remains a worrying reality, but no adequate attitudes toward affective-sexual diversity (AtASD) measure exists for Spanish adolescent students. We developed a 27-item scale including cognitive, affective, and behavioral aspects, which was completed by 696 secondary school students from the Madrid area. Factor analyses suggested a unidimensional model, Cronbach's alpha indicated excellent scale scores reliability, and item calibration under the item response theory framework showed that the scale is especially informative for homophobic attitudes. A hierarchical multiple regression analysis showed that variables traditiona…

Adapting and validating the Rosenberg Self-Esteem Scale for elderly Spanish population.
2019
ABSTRACTObjectives:This study aims to adapt and validate the most common measure of self-esteem, the Rosenberg Self-Esteem Scale (RSES), in the elderly Spanish population based on the initial one-factor model proposed by the author of the scale.Design:The factorial validity of the scale was tested using confirmatory factor analysis.Setting:The study was carried out in the city of Valencia (Spain).Participants:A total of 231 elderly people with a mean age 72.68 (SD=8.55).Measurements:The participants completed the questionnaire RSES for the validation process, sociodemographic data and Mini-Mental State Examination.Results:Confirmatory factor analysis with a five-item structure for the one-f…
Involvement of CB1 and CB2 receptors in the modulation of cholinergic neurotransmission in mouse gastric preparations.
2007
Abstract While most of the studies concerning the role of cannabinoids on gastric motility have focused the attention on the gastric emptying in in vivo animal models, there is little information about the cannabinoid peripheral influence in the stomach. In addition, the functional features of CB2 receptors in the gastrointestinal tract have been poorly characterized. The purpose of the present study was to investigate the effects of cannabinoid drugs on the excitatory cholinergic and inhibitory non-adrenergic non-cholinergic (NANC) neurotransmission in mouse isolated gastric preparations. Intraluminal pressure from isolated whole stomach was recorded and mechanical responses induced by ele…
Effects of menthol on circular smooth muscle of human colon: Analysis of the mechanism of action.
2014
Abstract Menthol is the major constituent of peppermint oil, an herbal preparation commonly used to treat nausea, spasms during colonoscopy and irritable bowel disease. The mechanism responsible for its spasmolytic action remains unclear. The aims of this study were to investigate the effects induced by menthol on the human distal colon mechanical activity in vitro and to analyze the mechanism of action. The spontaneous or evoked-contractions of the circular smooth muscle were recorded using vertical organ bath. Menthol (0.1 mM–30 mM) reduced, in a concentration-dependent manner, the amplitude of the spontaneous contractions without affecting the frequency and the resting basal tone. The in…
Research in China
2009
My stay in China began in November 1985 with a lecture at the opening of the Max Planck Guest Laboratory in the Institute of Cell Biology at the Chinese Academy of Sciences (CAS) in Shanghai (Hennig, 2000). It marked the beginning of 23 years of research and teaching at the Institute of Cell Biology and other universities throughout China. > Looking back after 23 years, the changes that have taken place in China could not have been predicted in 1985… In January 2001, I accepted a long‐term lectureship offered by the German Academic Exchange Service (DAAD; Bonn, Germany), which, with further support from CAS, allowed me to create my own research group within the Shanghai Institutes for Biolo…
