Fatigue in living kidney donors compared to a German general population sample: An exploratory study
Fatigue is less prevalent particularly in older donors and predictors of fatigue presented in the general population sample seem to have little importance in the donors. However, middle-aged female donors might be more prone to develop fatigue. This group may require more intense exploration before and after donation to detect and treat the underlying factors timely
Feasibility of the development and psychometric properties of a standardized screening instrument for mental disorders in patients with suspected rare diseases: Results of the ZSE-DUO study
The design of a new short screening instrument for mental disorders in patients presenting at CRDs was feasible. Furthermore, the new short screening instrument may help MHEs to identify patients in need of a more thorough screening and adapted care, particularly in identifying patients with potential depressive disorders. However, due to the heterogeneity of the mental disorders in this patient group, in addition, individual assessment of patien…
Reliability and validity of the German version of the DePaul Symptom Questionnaire Post-Exertional Malaise (DSQ-PEM)
In summary, this study confirms the strong psychometric properties of the German version of the DSQ-PEM and supports the instrument as a reliable and valid tool for measuring PEM in Germany and other German-speaking countries

Cognitive-behavioral and dietary weight loss intervention in adult kidney transplant recipients with overweight and obesity: Results of a pilot RCT study (Adi-KTx)
The obesity epidemic and its health consequences have not spared the population of kidney transplant (KTx) candidates and recipients. In addition, KTx recipients are susceptible to weight gain after transplantation. Overweight and obesity after KTx are strongly associated with adverse outcomes. Therefore, we designed a randomized controlled, mono-center study to specifically test the effectiveness of a primarily cognitive-behavioral approach supp…
Psychometric properties, factor structure, and German population norms of the multidimensional fatigue inventory (MFI-20)
The MFI-20 is a reliable and valid instrument for measuring fatigue in the general population, but the five-factor structure is not supported. The subscale general fatigue or the MFI-20 total score might measure fatigue sufficiently. The provided norms can be used for further research and individual assessment
Prevalence and clinical correlates of misophonia symptoms in the general population of Germany
Misophonia is a frequent condition and should further be examined as an independent diagnostic entity
In-Session-Reflective-Functioning in Anorexia Nervosa: An Analysis of Psychotherapeutic Sessions of the Antop Study
Patients with AN show a low capacity to mentalize in sessions, which seems to be at least partly dependent on the degree of starvation. The results suggest a possible relationship between an increase in in-session RF and outcome, which has to be replicated by further studies
The Relationship of Shopping-Related Decisions with Materialistic Values Endorsement, Compulsive Buying-Shopping Disorder Symptoms and Everyday Moral Decision Making
The findings indicate that a more egoistic everyday moral decision making style is not directly linked to domain-specific shopping-related decision making but strengthens the link between symptoms of CBSD and ego-oriented shopping-related decisions
Proposed diagnostic criteria for compulsive buying-shopping disorder: A Delphi expert consensus study
Gender-Dependent Associations of Anxiety and Depression Symptoms With Eating Disorder Psychopathology in a Representative Population Sample
Background: Evidence shows that anxiety and depressive disorders play an important role in eating disorder behavior. However, given the epidemiology of eating disorders, there is a need to investigate potentially gender-specific connections. Method: This study tested the associations of anxiety and depression symptoms with eating disorder symptoms and behaviors and explored whether they differed between men and women. Within a population-represen…
The Transplant Evaluation Rating Scale Predicts Clinical Outcomes 1 Year After Lung Transplantation: A Prospective Longitudinal Study
Objectives: It has been recommended that all candidates for lung transplantation undergo pre-transplant psychosocial evaluation for risk assessment. However, psychosocial issues are only important if they correlate with outcomes after transplantation. Methods: In this prospective study patients who were referred for lung transplantation from 2016 to 2018 ( n = 352) at Hannover Medical School were evaluated using the Transplant Evaluation Rating S…
Obesity After Kidney Transplantation—Results of a KTx360°Substudy
Our results suggest that obesity represents a serious problem in KTx patients, especially regarding the association between increasing BMI and decreasing graft functioning (eGFR). However, this aspect is often overlooked and information on effective treatment options for these patients are scarce making further research on this topic necessary
Body Image and Body Avoidance Nine Years After Bariatric Surgery and Conventional Weight Loss Treatment
Recently, there has been an increasing focus on body image dissatisfaction (BID), both as a motivational factor for seeking bariatric surgery and as a factor influencing weight loss outcome after surgery. Although associations have been reported between BID, emotional distress and successful weight loss, conclusions are limited due to methodological issues such as non-weight-specific assessment tools for body image and neglect of behavioral compo…
A Randomized Study of Food Pictures-Influenced Decision-Making Under Ambiguity in Individuals With Morbid Obesity
The results indicate that food pictures processing interferes with decision-making, regardless of weight status. Opposed to the hypothesis, stronger tendencies to avoid than to approach pictures presenting processed, tasty food were observed. Further research should examine how cognitive avoidance tendencies toward processed, high energy food and approach tendencies toward healthy food can be transferred to real life situations
Factor Analyses and Validity of the Transplant Evaluation Rating Scale (Ters) in a Large Sample of Lung Transplant Candidates
The two factors showed good psychometric properties, and differential convergent and predictive validity. However, further studies concentrating on the predictive value of the TERS and its factors regarding somatic outcomes (mortality, graft functioning) are required
Influence of Officially Ordered Restrictions during the First Wave of Covid-19 Pandemic on Physical Activity and Quality of Life in Patients after Kidney Transplantation in a Telemedicine Based Afterc…
Guidelines recommend a healthy lifestyle and regularly physical activity (PA) after kidney transplantation (KTx). The KTx360° program is a multicenter, multisectoral, multimodal, telemedicine-based follow-up care program. Effects of the first COVID-19 wave restrictions on health-related quality of life and PA of supervised KTx360° patients were evaluated using an online questionnaire. Six hundred and fifty-two KTx360° patients were contacted via …
Prevalence and Correlates of Cognitive Impairment in Kidney Transplant Patients Using the DemTect—Results of a KTx360 Substudy
Cognitive impairment in kidney transplantation (KTx) patients is associated with allograft survival and mortality. However, the prevalence of cognitive impairment after KTx is still understudied. Thus, we aimed to assess the prevalence of cognitive impairment in KTx patients and to identify sociodemographic, medical, donation-specific, and psychological variables associated with cognitive impairment. In this cross-sectional two-center study, 583 …
Association of Leptin Gene DNA Methylation With Diagnosis and Treatment Outcome of Anorexia Nervosa
Epigenetic alterations are increasingly implicated in the pathophysiology of anorexia nervosa (AN) but are as yet poorly understood. We investigated possible associations between the leptin gene ( LEP ) and the leptin receptor gene ( LEPR ) DNA promoter methylation and (1) a diagnosis of AN and (2) outcome after a 10 months psychotherapeutic outpatient treatment. 129 ( LEPR : n = 135) patients with AN were investigated during the large scale psyc…
Psychometric Properties of the German Version of the Pulmonary-Specific Quality-of-Life Scale in Lung Transplant Patients
The Pulmonary-Specific Quality-of-Life Scale (PQLS) is a validated self-report questionnaire assessing health-related quality of life (HRQoL) in patients with end-stage lung disease awaiting lung transplantation. The aim of our study was to evaluate the psychometric properties of the German version of the PQLS. One hundred and forty patients awaiting lung transplantation (55% men) with a median age of 53 years [Interquartile range (IQR) 13] answe…
Information Needs of Patients About Immunosuppressive Medication in a German Kidney Transplant Sample: Prevalence and Correlates
Background: Worldwide clinical guidelines for the care of kidney transplant (KT) recipients recognize the importance of health care providers imparting appropriate immunosuppressive medication (ISM) information for the facilitation of safe medication self-management. The extent of medication information made available is, however, not necessarily what patients require to know about their prescribed medicines. A useful indicator for determining th…

Partnership Satisfaction in Living Kidney Donors
Due to organ shortage, living kidney donation is gaining increasing importance. Medical progress enables a successful transplantation between unrelated individuals, even individuals with AB0-incompatibilities. Spouses are the largest group of living kidney donors. The aim of this study was to assess partnership status and partnership satisfaction in living kidney donors. In the cross-sectional study we investigated 361 living kidney donors. The t…
Metabolic Barriers to Weight Gain in Patients With Anorexia Nervosa: A Young Adult Case Report
Background: Over-proportionally high energy requirements in some patients with anorexia nervosa (AN) have been reported, but their exact origin remains unclear. Objective: To objectively measure metabolic alterations in an AN patient with high energy requirements as judged by clinical observation. Materials and Methods: We present the case of a young woman with AN (index patient, IP; 19 years, admission BMI 13.9 kg/m 2 ). After 3 months of treatm…
Coming to Terms With Risk Factors for Eating Disorders: Application of Risk Terminology and Suggestions for a General Taxonomy
The aims of the present review are to apply a recent risk factor approach (H. C. Kraemer et al., 1997) to putative risk factors for eating disorders, to order these along a timeline, and to deduce general taxonomic questions. Putative risk factors were classified according to risk factor type, outcome (anorexia nervosa, bulimia nervosa, binge-eating disorder, full vs. partial syndromes), and additional factor characteristics (specificity, potency…
Two Forms of Compulsive Consumption: Comorbidity of Compulsive Buying and Binge Eating
Several authors have articulated the need for broader theories or models to account for multiple forms of compulsive or addictive consumption. Development of these broader theories requires more information regarding the overlap and interrelationship of specific consumption disorders. Two studies are presented here to examine the comorbidity of compulsive buying and eating disorders involving binge eating. Study 1 found that women diagnosed as ha…

Cognitive-Perceptual Factors in Noncardiac Chest Pain and Cardiac Chest Pain
OBJECTIVE: Noncardiac chest pain (NCCP) is a common condition associated with considerable patient distress and substantial healthcare costs. Our aim was to investigate associations between illness perceptions, anxiety sensitivity, somatic amplification, and experience of chest pain, and to assess whether a multifactorial model including these factors can distinguish patients with NCCP from patients with cardiac chest pain (CCP). METHODS: A total…
Performance in Neurocognitive Tasks in Obese Patients. Does Somatic Comorbidity Matter
The aim of the present study was to examine if obese individuals with obesity-related somatic comorbidity (i.e., hypertension, diabetes, sleep apnea, dyslipidemia, pain disorder) perform worse in neurocognitive tasks compared to obese individuals without any somatic disorder. Neurocognitive functioning was measured by a computerized test battery that consisted of the following tasks: Corsi Block Tapping Test, Auditory Word Learning Task, Trail Ma…

A Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease (SPIRR-CAD): Results of an Observer-Blinded, Multicenter, Randomized Trial in Depressed Patients With Coronary Artery…
BACKGROUND: Depression predicts adverse prognosis in patients with coronary artery disease (CAD), but previous treatment trials yielded mixed results. We tested the hypothesis that stepwise psychotherapy improves depressive symptoms more than simple information. METHODS: In a multicenter trial, we randomized 570 CAD patients scoring higher than 7 on the Hospital Anxiety and Depression Scale-depression subscale to usual care plus either one inform…

Adaptive Personality Traits and Psychosocial Correlates among Living Kidney Donors
Since living kidney donors have repeatedly been shown to be mentally more healthy compared to the general population, they might also exhibit more adaptive personality characteristics. We investigated the personality traits of 315 living kidney donors (202 female and 113 male donors) on average 7.1 years after donation using the NEO-Five Factor Inventory, a frequently used personality inventory measuring the "big five" dimensions of personality (…

Psychosocial Variables Associated with Immunosuppressive Medication Non-Adherence after Renal Transplantation
In the posttransplant follow-up, kidney recipients with lower perceived social support, lower mental and higher physical health-related quality of life, and younger age can be regarded as a risk group for immunosuppressive medication non-adherence. In follow-up contacts with kidney transplant patients, physicians may pay attention to these factors. Furthermore, psychosocial interventions to optimize immunosuppressive medication adherence can be d…
