The eating disorder examination-questionnaire 8: A brief measure of eating disorder psychopathology (EDE-Q8)
Objective The aim of this study was to develop, evaluate, and standardize a short form of the well-established Eating Disorder Examination-Questionnaire (EDE-Q). The newly developed EDE-Q8 was required to reflect the originally postulated structure of the EDE-Q. Method Data were drawn from two nationwide representative population surveys in Germany: a survey conducted to develop the EDE-Q8 in 2009 (N = 2,520); and a survey conducted in 2013 (N = 2,508) for the evaluation and calculation of EDE-Q8 percentiles. Results The EDE-Q8 had excellent item characteristics, very good reliability and a very good model fit for the postulated second-order factorial structure. Furthermore, a strong correl…
Psychometric evaluation of the Generalized Anxiety Disorder Screener GAD-7, based on a large German general population sample.
Abstract Background The Generalized Anxiety Disorder Scales GAD-7 and GAD-2 are instruments for the assessment of anxiety. The aims of this study are to test psychometric properties of these questionnaires, to provide normative values, and to investigate associations with sociodemographic factors, quality of life, psychological variables, and behavioral factors. Methods A German community sample (n=9721) with an age range of 18–80 years was surveyed using the GAD-7 and several other questionnaires. Results Confirmatory factor analyses confirmed the unidimensionality and measurement invariance of the GAD-7 across age and gender. Females were more anxious than males (mean scores: M=4.07 vs. M…
Validation of the German Version of the Power of Food Scale in a General Population Sample
<b><i>Objective:</i></b> The Power of Food Scale (PFS) is a self-report instrument for assessing appetitive motivation in the absence of caloric needs. The study aim was to validate the German PFS version in a large population sample. <b><i>Methods:</i></b> Complete information on all PFS items was available from 2,421 respondents (age ≥14) of a nationally representative sample of the German population. We examined the psychometric properties of the German PFS version and provided population-based normative data. <b><i>Results:</i></b> The 3-factor structure of the original scale was replicated in confirmatory factor an…
Psychometric Evaluation of the Eating Disorder Examination Adapted for Children
The Eating Disorder Examination adapted for children (ChEDE) is the child version of the semi-structured gold standard eating disorder interview for adults. This study was a comprehensive test statistic evaluation of the German ChEDE in a large sample of children and adolescents with anorexia nervosa, binge eating disorder, loss of control eating, overweight and obesity, as well as non-eating-disordered and chronically ill control probands (n = 352). Excellent inter-rater reliability, adequate internal consistency and satisfactory stability of ChEDE indicators were demonstrated. ChEDE indicators discriminated between diverse forms of eating and weight disturbances and normative eating and w…
The Core Self-Evaluation Scale: Psychometric properties of the German version in a representative sample
The Core Self-Evaluation Scale (CSES) is an economical self-reporting instrument that assesses fundamental evaluations of self-worthiness and capabilities. The broad aims of this study were to test the CSES's psychometric properties. The study is based on a representative survey of the German general population. Confirmatory factor analyses were conducted for different models with 1, 2, and 4 latent factors. The CSES was found to be reliable and valid, as it correlated as expected with measures of depression, anxiety, quality of life, self-report health status, and pain. A 2-factor model with 2 related factors (r = -.62) showed the best model fit. Furthermore, the CSES was measurement invar…
Psychometric evaluation of the Eating Disorders in Youth-Questionnaire when used in adults: Prevalence estimates for symptoms of avoidant/restrictive food intake disorder and population norms.
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,…
Prevalence of Chronic Disabling Noncancer Pain and Associated Demographic and Medical Variables
OBJECTIVES In population surveys, up to 30% of participants reported chronic pain. Reports of chronic pain do not necessarily imply disability associated with pain. We assessed the prevalence of chronic disabling noncancer pain and associated demographic and medical variables in a sample of the general German population. METHODS A cross-sectional survey was conducted with 4360 people aged 14 years and above, who were representative of the German population. Measures were obtained for demographic variables, presence of chronic pain (based on the definition of the International Association for the Study of Pain), chronic pain stages (based on a chronic pain grade questionnaire), and disease l…
