Effects of a single session of SMR neurofeedback training on anxiety and cortisol levels.
2020
Objectives: According to some studies, a putatively calming effect of EEG neurofeedback training could be useful as a therapeutic tool in psychiatric practice. With the aim of elucidating this possibility, we tested the efficacy of a single session of ¿sensorimotor (SMR)/¿theta neurofeedback training for mood improvement in 32 healthy men, taking into account trainability, independence and interpretability of the results. Methods: A pre-post design, with the following dependent variables, was applied: (i) psychometric measures of mood with regards to anxiety, depression, and anger (Profile of Mood State, POMS, and State Trait Anxiety Inventory, STAI); (ii) biological measures (salivary leve…
Genetic and environmental influences on longitudinal changes in leisure-time physical activity from adolescence to young adulthood.
2013
The aim of this study was to estimate genetic and environmental influences on the longitudinal evolution of leisure-time physical activity habits from adolescence to young adulthood. Data were gathered at four time points, at mean ages 16.2, 17.1, 18.6, and 24.5 years. At baseline, the sample comprised 5,216 monozygotic and dizygotic twins, born 1975–1979, and, at the last follow-up point, of 4,531 monozygotic and dizygotic twins. Physical activity volume was assessed as frequency of leisure-time physical activity and participants were categorized into three groups: inactive, moderately active, and active. Genetic and environmental influences were estimated using a multivariate, longitudina…
The gene expression profile of cumulus cells reveals altered pathways in patients with endometriosis
2014
PURPOSE: The objective of this experimental study was to compare the global gene expression profile of CC of mature oocytes in 18 patients with severe endometriosis and CC in 18 control patients affected by a severe male factor. METHODS: For each group, the CC were pooled, RNA was extracted and a microarray performed. For validating the microarray, a quantitative real-time PCR was performed in the CC of an independent set of patients with endometriosis (n = 5) and controls (n = 7). RESULTS: 595 differentially expressed genes (320 down-regulated, 275 up-regulated, p < 0.05, fold change ≥1.5) were identified. The most significant changes were observed in genes involved in the chemokine signal…
The role of stress and self-efficacy in somatic and psychological symptoms during the climacteric period - Is there a specific association?
2019
Abstract Objectives To investigate the influence and specificity of sociodemographic and psychological factors on the perception of symptoms associated with menopause. Study design Data are based on a nationwide cross-sectional survey study in Germany. A representative sample of 1350 females aged 14–95 years was examined. Sociodemographic factors, perceived stress, and self-efficacy were assessed. Women were divided into three age groups (young women ≤ 44 years; perimenopausal women 45–60 years; older women ≥ 61 years), and the Menopause Rating Scale (MRS) was used over the entire life span. Main outcome measures Total score on the Menopause Rating Scale (MRS) and hot flushes/sweating asses…
Construction and testing of the Moral Development Scale for Professionals (MDSP)
2010
Moral development among students is central for nursing education, because nursing is informed by moral ends, and it is essential that professional nurses have a well developed ability for moral behaviour, ethical reasoning and decision making. The aim of this study was to construct a new instrument for measuring moral development according to Kohlberg's theory of moral development among students and professionals, and initially test it for reliability and validity among students in professional education. Thirty-two items following the conventional and postconventional stages in the theory were developed. Different actions for reducing the items were implemented. The final version of the i…
Psychometric evaluation of the Eating Disorders in Youth-Questionnaire when used in adults: Prevalence estimates for symptoms of avoidant/restrictive…
2020
Objective Restrictive eating behaviors occur across ages, but little is known about symptoms of avoidant/restrictive food intake disorder (ARFID), especially in adults. This study sought to examine the prevalence of symptoms of ARFID in the adult population, providing a psychometric evaluation of the Eating Disorders in Youth-Questionnaire (EDY-Q) and population norms. Method In a representative survey of the German population, N = 2,424 adults (1,297 women, 1,127 men; age 49.5 ± 17.5 years) were assessed with the EDY-Q and measures of eating disorder and general psychopathology for divergent validation. Results The point prevalence of self-reported symptoms of ARFID amounted to 0.8% (20/2,…
Validation of the German version of the Bodily Distress Syndrome 25 checklist in a representative German population sample
2020
Abstract Objective The Bodily Distress Syndrome 25 (BDS 25) checklist is a self-report instrument that can be used for case finding of a BDS in both clinical practice and research. We assessed the reliability and the internal and external validity of the German version of the BDS 25 in a sample of the general German population. Methods The psychometric properties of the BDS 25 German were examined in a representative cross-sectional German population survey which included 2386 persons aged ≥14 years. Validation instruments included the Somatic Symptom Scale 8, the Giessen Subjective Complaints List 8 and the Patient Health Questionnaire 4. Participants were asked if they had been diagnosed …
Measurement invariance of the Satisfaction with Life Scale by gender, age, marital status and educational level
2019
Introduction The Satisfaction with Life Scale (SWLS) has shown strong evidence of acceptability, reliability, validity and invariance for gender, whereas there is mixed evidence of invariance by culture and age and the literature has not explored the roles of marital status and educational level. The SWLS should be invariant by marital status and educational level to be able to compare scores between groups. We aimed to explore the invariance of the SWLS by marital status and educational level. Method A convenience sample of 726 Spanish adults participated in a survey. We tested a one-factor model using confirmatory factor analysis. We tested the configural, metric and scalar invariance of …
Validation of the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Spanish women
2014
Contains fulltext : 124145.pdf (Publisher’s version ) (Closed access) The Dutch Eating Behavior Questionnaire (DEBQ) was developed to measure eating styles that may contribute to or attenuate the development of overweight. It comprises three scales that measure emotional, external and restrained eating. The main goal of this study is to evaluate the internal structure of the Spanish version of the DEBQ using updated psychometric techniques in a sample of women. A sample of 647 Spanish females answered the questionnaire. Both exploratory structural equation modeling and confirmatory factor analysis were used to evaluate the factor structure of the DEBQ. Reliabilities were estimated with Cron…
A brief form of the Perceived Social Support Questionnaire (F-SozU) was developed, validated, and standardized
2015
Abstract Objectives Development of a brief instrument (F-SozU K-6) for the measurement of perceived social support in epidemiologic contexts by shortening a well-established German questionnaire (F-SozU K-14). Study Design and Setting The development of the F-SozU K-6 consisted of two phases; phase 1: the F-SozU K-14 was presented to a general population sample representative for the Federal Republic of Germany (N = 2,007; age: 14–92 years). Six items for the short form were selected based on the maximization of coefficient alpha. Phase 2: the new short form (F-SozU K-6) was evaluated and standardized in an independent second population survey (N = 2,508, age: 14–92 years). Results The F-So…
