As such, relevant intervention programs should address these aspects, and the effectiveness of such programs should be determined by assessing improvement in activities and participation. However, no patient-centred and psychometrically sound outcome measures for this purpose are available so far. Objectives The objectives of this study were to develop and to validate a new outcome measure, the PaArticular Scales, to quantify activities and participation in older individuals with joint contractures. Specific aims were (A) to operationalize the content of an International Classification of Functioning, Disability and Health-based standard set towards meaningful questions and to combine them to a questionnaire and (B) to assess the psychometric properties of the developed questionnaire, in detail to evaluate test-retest reliability, objectivity, internal consistency reliability and criterion validity. Design Operationalization was reached by an expert consensus conference and a subsequent expert Delphi survey. Psychometric properties were assessed in a cross-sectional study. Settings Nursing homes, geriatric rehabilitation facilities. Participants 23 experts (nurses, physicians, physical and occupational therapists) participated in the consensus conference and the Delphi survey. A total of 191 individuals with joint contractures (as confirmed by physician, nurse or physical therapist) between 65 and 102 years, living in nursing homes or as patients in geriatric rehabilitation were enrolled in the cross-sectional study. Methods Rasch Partial Credit Modelling. Results The consensus conference and Delphi survey resulted in a questionnaire with 86 items of the International Classification of Functioning, Disability and Health. Test-retest-reliability among those was acceptable (Cohen's weighted kappa: 0.779). The Rasch analysis revealed two independent interval-scaled scales with 24 items for the Activities scale and 11 items for the Participation scale with high internal consistency reliability. Cronbach's alpha was 0.96 for the Activities scale and 0.92 for the Participation scale. Criterion validity was -0.40 and -0.30 for the Activities scale and for the Participation scale, respectively. Conclusions The PaArticular Scales, a new patient-centred and psychometric sound outcome measures to comprehensively assess the impact of joint contractures in geriatric care, are available now. These developed scales will serve as primary outcomes in a scheduled evaluation of a complex intervention to improve participation and quality of life in nursing home residents with joint contractures.}, language = {de} } @article{BartoszekFischerClarmannvonClarenauetal.2015, author = {Bartoszek, Gabriele and Fischer, Uli and Clarmann von Clarenau, Stephan and Grill, Eva and Mau, Wilfried and Meyer, Gabriele and Strobl, Ralf and Thiesemann, R{\"u}diger and Nadolny, Stephan and M{\"u}ller, Martin}, title = {Development of an International Classification of Functioning, Disability and Health (ICF)-based standard set to describe the impact of joint contractures on participation of older individuals in geriatric care settings}, series = {Archives of gerontology and geriatrics}, volume = {61}, journal = {Archives of gerontology and geriatrics}, editor = {Science direct,}, year = {2015}, abstract = {Introduction Joint contractures are characterized as impairment of the physiological movement of joints due to deformity, disuse or pain and have major impact especially for older individuals in geriatric care. Some measures for the assessment of the impact of joint contractures exist. However, there is no consensus on which aspects should constantly be measured. Our objective was to develop a standard-set based on the ICF for describing functioning and disability in older individuals with joint contractures in geriatric care settings, giving special emphasis to activities and participation. Methods The ICF-based standard set was developed in a formal decision-making and consensus process and based on an adapted version of the protocol to develop ICF Core Sets. These are sets of categories from the ICF, serving as standards for the assessment, communication and reporting of functioning and health for clinical studies, clinical encounters and multi-professional comprehensive assessment and management. Results Twenty-three experts from Germany and Switzerland selected 105 categories of the ICF component Activities and Participation for the ICF-based standard set. The largest number of categories was selected from the chapter Mobility (50 categories, 47.6\%). Conclusions The standard set for older individuals with joint contractures provides health professionals with a standard for describing patients' activity limitations and participation restrictions. The standard set also provides a common basis for the development of patient-centered measures and intervention programs. The preliminary version of the ICF-based standard set will be tested in subsequent studies with regard to its psychometric properties.}, language = {en} }
