Translation and psychometric properties of the King's Sarcoidosis Questionnaire (KSQ) in German language.

Background: King's Sarcoidosis Questionnaire (KSQ) is a novel, validated, health-related quality of life questionnaire on sarcoidosis with 5 scales and 29 items. For future multinational observational and interventional studies on sarcoidosis, a validated German version of the KSQ is needed. The objective of our study is to translate the original KSQ and develop a German version possessing good psychometric properties and with as few modifications as possible.

Yellow flags as predictors of rehabilitation outcome in chronic low back pain.

Objective: While it is agreed that yellow flags (prognostic psychosocial factors for poor recovery in low back pain) predict pain-related outcomes, uncertainty remains regarding which constructs are the central ones, particularly as there is considerable conceptual overlap between constructs. Therefore, the aim of our study was to analyze the distinctiveness of different psychological factors in predicting rehabilitation outcomes in a sample of patients with chronic low back pain (CLBP) in a rehabilitation setting. Research Method/Design: We conducted a longitudinal study using multivariable modeling taking into account a broad set of psychological variables as potential predictors.

Illness Beliefs, Treatment Beliefs and Information Needs as Starting Points for Patient Information: The Evaluation of an Intervention for Patients with Depression.

Patients with depression are often dissatisfied with disease- and therapy-related information. The objective of this study was to evaluate an intervention that applied the Common Sense Model to the provision of information during inpatient rehabilitation for patients with depression. The intervention was evaluated in a sequential control group design.

Psychometric Properties of a German Translation of the PROMIS® Depression Item Bank.

The patient-reported outcome measurement information system (PROMIS) initiative has developed and evaluated a set of publicly available, efficient, and flexible measures of patient-reported outcomes in different health domains, including mental health. The objective of this study was to translate the PROMIS Depression item bank into German and evaluate the psychometric properties of the translated items. Items were translated using forward and backward translation and cognitive interviews.

Illness and treatment perceptions of patients with chronic low back pain: characteristics and relation to individual, disease and interaction variables.

The significance of various cognitive and psychosocial factors in the development, progression and persistence of chronic low back pain (CLBP) is well demonstrated. However, only a few studies have addressed CLBP patients' cognitive representations or beliefs about their disease and its treatment. The present study aimed to: (1) describe the illness and treatment beliefs of patients with CLBP, e.

Development and evaluation of the PI-G: a three-scale measure based on the German translation of the PROMIS ® pain interference item bank.

Objective: Study aim was to translate the PROMIS(®) pain interference (PI) item bank (41 items) into German, test its psychometric properties in patients with chronic low back pain and develop static subforms.

Methods: We surveyed N = 262 patients undergoing rehabilitation who were asked to fill out questionnaires at the beginning and 2 weeks after the end of rehabilitation, applying the Oswestry Disability Index (ODI) and Pain Disability Index (PDI) in addition to the PROMIS(®) PI items. For psychometric testing, a 1-parameter item response theory (IRT) model was used.

Development and Psychometric Evaluation of a German Version of the PROMIS® Item Banks for Satisfaction With Participation.

The Patient Reported Outcomes Measurement Information System (PROMIS) initiative aims to provide reliable and precise item banks measuring patient-reported outcomes in different health domains. The aim of the present work was to provide a German translation of the PROMIS item banks for satisfaction with participation and to psychometrically test these German versions. Cognitive interviews followed a forward-backward translation.

Illness beliefs and treatment beliefs as predictors of short-term and medium-term outcome in chronic back pain.

Objective: Patients' illness beliefs were shown to be more relevant than other psychosocial factors of influence for predicting outcome in back pain in primary care. The aim of this study was to determine whether illness beliefs and beliefs about rehabilitation are predictors of functioning, pain intensity, and coping with pain after rehabilitation in a population with longstanding chronic back pain.

Design And Patients: The study included 110 patients with longstanding chronic back pain in a longitudinal study design with 3 measurement points (before rehabilitation, end of rehabilitation, and 6 months follow-up).

Illness beliefs and treatment beliefs as predictors of short and middle term outcome in depression.

The article investigates whether illness beliefs and beliefs about rehabilitation are predictors of short and middle term outcome in depression even when adjustments are made for variables, which are known to be predictors of the course of depression. Within the context of a non-controlled prospective study design, data were analyzed using forced entry hierarchical multiple regression analyses. The sample comprised N = 98 patients.

Illness beliefs, treatment beliefs and information needs as starting points for patient information--evaluation of an intervention for patients with chronic back pain.

Objective: The objective of the study was to evaluate an intervention which applied the extended Common Sense Model to the provision of information about illness and treatment during inpatient rehabilitation for patients with chronic back pain.

Methods: The intervention was evaluated in a sequential control group design (control group N=105; intervention group N=96). Changes with respect to illness and treatment beliefs, satisfaction with information, and health status at the end of rehabilitation were selected as outcome measures.
