From Bi-Dimensionality to Uni-Dimensionality in Self-Report Questionnaires
2021
Abstract. The common factor model – by far the most widely used model for factor analysis – assumes equal item intercepts across respondents. Due to idiosyncratic ways of understanding and answering items of a questionnaire, this assumption is often violated, leading to an underestimation of model fit. Maydeu-Olivares and Coffman (2006) suggested the introduction of a random intercept into the model to address this concern. The present study applies this method to six established instruments (measuring depression, procrastination, optimism, self-esteem, core self-evaluations, and self-regulation) with ambiguous factor structures, using data from representative general population samples. I…
Psychometric evaluations of the Life Orientation Test-Revised (LOT-R), based on nine samples
2021
The aim of this study was to examine psychometric properties of the Life Orientation Test-Revised (LOT-R).The LOT-R was administered in five clinical samples, three samples of the adult general population, and one sample of adolescents. Seven of the studies were performed in Germany and two in Colombia. All of the sample sizes were above 300.Cronbach's alpha coefficients were between .57 and .75 for the eight adult samples, the correlations between the scales optimism and pessimism ranged from -.05 to -.37, and the coefficients of temporal stability (test-retest correlations) of the scales ranged from .43 to .69. There were no systematic age and gender effects observed in the nine studies. …
The role of self-compassion in the relationship between attachment, depression, and quality of life.
2019
Abstract Background Self-compassion may be shaped by early attachment experiences, and has been linked to mental health and well-being. This study examined the role of two distinct features of self-compassion, self-warmth and self-coldness, in the relationship between attachment insecurity and depression as well as quality of life in a general population sample in Germany. Methods Participants (N = 2,253; 53.4% female, Mage 50 years) completed the Self-Compassion Scale (SCS), Adult Attachment Scale (AAS), Beck Depression Inventory-Fast Screen (BDI-FS), and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Mediation analysis was used to…
Patient participation in the medical decision-making process in haemato-oncology - a qualitative study
2013
Cancer patients are showing increased interest in shared decision-making. Patients with haematological illnesses, however, express considerably less desire for shared decision-making as compared with other oncological patient groups. The goal of the current project was to identify the reasons for the lower desire for shared decision-making among patients with haematological illness. We conducted qualitative, semi-structured interviews with 11 haematological patients (39-70 years old) after the beginning of therapy concerning the course and evaluation of medical shared decision-making. The patients were often overwhelmed by the complexity of the illness and the therapy and did not want to as…
The Core Self-Evaluation Scale: Psychometric properties of the German version in a representative sample
2014
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…
