2015
AbstractObjectiveThe present study aimed to translate the English version of the Nutritional Form For the Elderly into Simplified Chinese, as well as to test the reliability (homogeneity and stability) and validity (content and construct validity) of the Chinese version of the Nutritional Form For the Elderly (NUFFE-CHI).DesignThe study adopted a cross-sectional design. The English version of the NUFFE was translated into Simplified Chinese and a questionnaire survey was conducted. The data were analysed with statistical methods to estimate the homogeneity, stability, content and construct validity.SettingJinzhou City, China.SubjectsA total number of 701 community-dwelling older adults answ…
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…
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…
Positive and Negative Affect Schedule (PANAS): psychometric properties of the online Spanish version in a clinical sample with emotional disorders
2020
Abstract Background The Positive and Negative Affect Schedule (PANAS) is the most widely and frequently used scale to assess positive and negative affect. The PANAS has been validated in several languages, and it has shown excellent psychometric properties in the general population and some clinical samples, such as forensic samples, substance users, and adult women with fibromyalgia. Nevertheless, the psychometric properties of the scale have not yet been examined in clinical samples with anxiety, depressive, and adjustment disorders. In addition, the proliferation of Internet-based treatments has led to the development of a wide range of assessments conducted online with digital versions …
Cyberbullying among Adolescents: Psychometric Properties of the CYB-AGS Cyber-Aggressor Scale
2020
The present study aims to analyze the psychometric properties of the revised version of the Adolescent Cyber-Aggressor scale (CYB-AGS). This scale is composed of 18 items that measure direct and indirect cyberbullying. A cross-sectional study was conducted using two independent samples of adolescents. The first sample included 1318 adolescents (52.6% girls) from 12 to 16 years old (M = 13.89, SD = 1.32). The second sample included 1188 adolescents (48.5% boys) from 12 to 16 years old (M = 14.19, SD = 1.80). First, to study the psychometric properties of the CYB-AGS, exploratory factor analysis was performed on Sample 1. Results indicated a two-factor structure: direct cyber-aggression and i…
Reliability and validity of the COPE Index among caregivers of disabled people.
2017
Aim To study the reliability and validity of the Carers of Older People in Europe (COPE) Index among caregivers of disabled people of different ages. Methods A cross-sectional design of Finnish caregivers (n = 1117). Exploratory factor analysis (EFA) was performed separately on samples of three different age groups, and the internal consistencies of the subscales were investigated. Results Three factors were identified; Cronbach's alpha was 0.83–0.86 for negative impact and 0.77–0.78 for quality of support, indicating good internal consistency. The third factor, positive value, was less consistent across the age groups (α < 0.66). Conclusions The COPE Index is a valid and reliable screening…
Construct validity of the anxiety sensitivity index-3 in clinical samples
2012
"Using two clinical samples of patients, the presented studies examined the construct validity of the recently revised Anxiety Sensitivity Index-3 (ASI-3). Confirmatory factor analyses established a clear three-factor structure that corresponds to the postulated subdivision of the construct into correlated somatic, social, and cognitive components. Participants with different primary clinical diagnoses differed from each other on the ASI-3 subscales in theoretically meaningful ways. Specifically, the ASI-3 successfully discriminated patients with anxiety disorders from patients with nonanxiety disorders. Moreover, patients with panic disorder or agoraphobia manifested more somatic concerns …
