“…Ladwig et al (2010) used the item on suicidal ideation from the Patient Health Questionnaire-9 ''In the last 2 weeks, have you had thoughts that you would be better off dead or of hurting yourself in some way?'' In the present study, participants had to endorse one of two items from the DESC (Forkmann et al, 2009) to become classified as reporting suicidal ideation. These items might represent a lower level of severity of suicidal ideation (see ''Methods'' for wordings).…”

The present study aimed to determine the prevalence of suicidal ideation in a representative sample of the German general population and examined its relation to potential risk factors. The study sample consisted of 2509 persons. Mean age was 49.4 years (SD, 18.2 years; 55.8% women). Participants filled in the Hospital Anxiety and Depression Scale and two items from the Rasch-based Depression Screening measuring suicidal ideation. Suicidal ideation was reported by 8.0% (n = 211) of all participants. People reporting suicidal ideation were less likely to be married or living together with a partner and to have children aged 6 to 13 years and were more likely to be divorced. They reported significantly higher levels of a depressive syndrome (t = 17.78; p < 0.001) and an anxiety syndrome (t = 18.43; p < 0.001). The study showed high point prevalence for suicidal ideation in the general German population. In concordance with results from similar studies in other countries, living alone and reporting anxious and depressive syndromes was associated with suicidal ideation.

“…The Rasch-based Depression Screening (DESC; Forkmann et al, 2009Forkmann et al, , 2010 was developed as onedimensional measure to screen for depression in patients suffering from both mental and somatic disorders. The 10 items of the DESC refer to the last 2 weeks, and participants are asked to indicate how often they experienced each symptom on a 5-point Likert-scale ranging from ''never'' (0) to ''always'' (4), with higher scores indicating more symptoms of depression and total scores of ]12 suggesting the presence of a depressive episode.…”

Furthermore, a correlation between two of the three factors equaled .76, pointing in the direction of summarizing these two factors into a single one.…”

Decentering is described as referring to one's current mental experiences from an objective perspective. This study presents a psychometric evaluation of a German version of the Experiences Questionnaire (EQ-D), a self-report instrument designed to measure decentering. Confirmatory factor analysis on a sample of 506 university students indicates acceptable-to-good model fit (χ(2)=58.3; TLI=.92; CFI=.95; RMSEA=.067) for a second-order factor Overall Decentering comprising the two first-order factors Accepting Self-Perception and Distanced Perspective. Preliminary evidence for the validity of the EQ-D was demonstrated via negative correlations with measures of depression and depressive rumination. The present results stress the multidimensional nature of decentering and provide important suggestions for future research on how to investigate and operationalize the decentering construct.

Constructing a Common Scale Between Tests of Depression: The use of Item Response Theory for Transferring of Norms from the BDI to EBADEP-A

et al. 2017

This study of depression assessment aims to demonstrate the process of joint calibration and transfer standards between the internationally recognized BDI and EBADEP-A, a new instrument recently validated in Brazil. In addition to the illustration of methodological procedures, our study is intended to contribute to the elaboration of normative references for the latter instrument as an assessment of depression symptoms. We included 1666 participants divided into subgroups of patients and nonpatients. The respondents answered the EBADEP-A and the Brazilian version of BDI. Data were analyzed using the Rasch-Andrich Rating Scale Model. We performed concurrent calibration of items of both instruments. Next, for each instrument we performed calibration with item parameters fixed based on prior analysis. Based on that, norms of the BDI were transfered to EBADEP-A. This procedure can be applied to any test that measures the same construct. This procedure produces a scale on the same metric. Keywords IRT; psychological assessment; humor disorders; psychometric properties; depression RESUMEN Este estudio de evaluación de la depresión tiene como objetivo demostrar el proceso de calibración y transferencia conjunta entre el BDI y el EBADEP-A, un nuevo instrumento validado en Brasil.
