A reanalysis of the center for epidemiological studies depression scale (CES-D) using non-parametric item response theory
2020
Abstract The “Center for Epidemiological Studies Depression Scale” (CES-D; Radloff, 1977 ) is a questionnaire used world-wide to measure depressive symptoms. Although the original four-factor-structure has been widely accepted and replicated, some studies point to other factor-structures like a one- and two-factor-structure. The goal of the current study was to evaluate the factor structure of the CES-D (one-, two- and four-factor-structure), which was found using classical test theory (CTT), with two non-parametric item-response-theory-models (Mokken-Scaling; Monotone-homogeneity-model; MHM and Double-monotonicity-model; DMM). To this end, a representative German sample was analyzed (N = 2…
Normierung und Evaluation der Messinvarianz der 8-Item-Kurzform der Center of Epidemiological Studies-Depression Scale (CES-D-8)
2020
Measurement invariance and normative data of the 8-item short form of the Center of Epidemiological Studies-Depression Scale (CES-D-8) Objectives: Female gender is a risk factor for depression. It is questionable whether a given psychometric instrument depicts depressive symptom severity in men and women alike. Therefore, we examined measurement invariance of the Center of Epidemiological Studies Depression Scale-8 (CES-D-8) between women, men and different age groups. Additionally, we aimed providing normative data for CES-D-8. Methods: We assessed depressive symptoms in a German population-based sample (N = 2,507) with the CES-D-8. Gender-distorted items were excluded in the short form. R…
Dimensional Latent Structure of Relationship Quality: Results of Three Representative Population Samples
2015
One central issue for every latent construct in psychology (e.g., relationship quality) is its latent nature: Differences in intelligence, for example, are traditionally considered to be dimensional (e.g., when quantifying intelligence by a standardized test score) rather than categorical (distinguishing different categories such as intelligent vs. unintelligent). When considering a categorical construct, such as Down syndrome, on the other hand, the characteristic is qualitative (groups are classified by existence or absence of an extra chromosome) rather than quantitative (varying degrees of Down syndrome). The group bound together by the possession of a certain characteristic (disease, d…
Psychometric properties of the Somatic Symptom Scale 8 (SSS-8) in a representative sample of German adolescents.
2021
Abstract Objective The psychometric properties of the Somatic Symptom Scale 8 (SSS-8) have been investigated in different studies. However, there is no study examining its psychometric properties on representative data of adolescents. The study at hand will present results from a large representative sample of German adolescents (13 to 18 years). Methods The following analyses draw on cross-sectional data from German ninth-grade students collected in 2015. Altogether, 10,638 individuals were surveyed with a return rate of 68.5% as part of a periodic representative survey in the German federal state of Lower Saxony. Results For the SSS-8, coefficient omega for the full sample was ω = 0.90, a…
