“…This means that the expected score on any of the POES items should be the same, irrespective of group identity. In addition to the groups mentioned, diagnosis groups are included in the present DIF analysis as is consistent with previous research [ 25 ]. People with psychosis may be assumed to have certain problems in asserting their lives compared to those with a less fragmented self-perception [ 26 ].…”

PurposeThe Profiles of Occupational Engagement in people with Severe mental illness (POES) instrument was developed to study time use profiles of occupations and measure the extent they are characterized by engagement. However, the dimensional factors are not known. The aim of the present study was to establish the internal construct validity of the POES using the Rasch measurement model.MethodsA sample of 192 outpatients in Sweden was administered the POES and data were subjected to Rasch analysis.ResultsThe POES showed good fit to the Rasch model after accommodation for local dependency. The nine items had high reliability as measured by person separation index, and no threshold disordering was present. Differential item functioning analysis showed no significant differences across groups of age, sex, diagnosis, or country of origin.ConclusionThe POES is a unidimensional scale that represents a continuum of occupational engagement. The transformed POES sum score can be used on an interval scale to measure status and changes in occupational engagement in mental health practice and research.

“…In Rasch analyses, response patterns are tested against strict standards for constructing invariant measures. Failure to fulfill the model requirements can contribute to a deeper insight into the construct validity of an instrument and its improvement [ 30 ].…”

BackgroundEconomic environmental factors represent important barriers to participation and have deleterious effects on quality of life (QOL) in persons with spinal diseases (SpD). While economic factors are anchored in the International Classification of Functioning, Disability and Health, their influence on QOL and participation from patients’ perspectives is an infrequent focus of research. The aim of the present research is to calibrate a culturally adapted Rasch-based questionnaire assessing economic QOL in patients with SpD.MethodsThe 11-items of the German economic-QOL-scale were answered by 325 patients with SpD on a four-point Likert-scale. Fit to the Rasch measurement model was investigated by testing for stochastic ordering of the items, unidimensionality, local independence, and differential item functioning (DIF).ResultsAfter adjusting for local dependency, fit to the Rasch model was achieved with a non-significant item-trait interaction (chi-squaredf = 20 = 34.8, p = 0.021). The person separation reliability equaled 0.88, the scale was free from age- or gender-related DIF, and unidimensionality could be verified.ConclusionsThe Rasch-based German version of the economic-QOL-scale represents a suitable instrument to investigate the influences of economic factors on patients’ QOL at a group and individual level. It can be easily applied in research and practice and may be administered quickly in combination with other instruments. The short test duration implies a low test burden for patients and a minimum of time expenditure by clinicians when evaluating the results.

“…In general, the total score of these scales is obtained by summing up the single item scores, assessed on a Likert scale. Interestingly, some of these scales have already undergone a thorough analysis of their metric properties, according to the Rasch model [87][88][89] and have been upgraded from ordinal to numerical scales, thus being more suited for being used in future research studies.…”

Objective Cancer-related fatigue (CRF) is a disabling chronic condition that cancer survivors could experience during and after recovery and that might benefit from self-managed physical activity (PA) programs. This scoping review aimed to map self-managed PA interventions found in literature for the management of CRF. Methods Given the heterogeneity of the topic, scoping review methodological frameworks were used. Pubmed, Cinahl and Cochrane databases were searched for primary literature. Inclusion criteria: self-managed PA meant as any exercise program prescribed by a professional either with or without initial supervision and training which then continued independently for a given time frame; patient-reported fatigue assessment included in the outcome measures. Articles dealing with entirely supervised interventions, dietary or psychological-only therapies, and with palliative care were excluded. Results Of the 543 experimental or observational studies screened, 63 were included. Of these forty-three studies were randomized controlled trials. Data were summarized in tables describing self-managed interventions according to: type of self-managed activity, frequency and duration, strategies to promote adherence, professionals supervising the treatment, outcome measures, and efficacy. A narrative synthesis was also added to further explain findings. Conclusions We collected the available evidence on PA when this was self-managed by patients after prescription by a healthcare provider. Clinicians and researchers should consider incorporating self-care programs in CRF patients’ recovery journey gradually, identifying the best strategies to integrate them into daily life. Researchers should specify the characteristics of PA programs when designing new studies. This review highlighted the areas to be investigated for future studies pertaining to self-managed PA.

Construct Validity of the Swedish Version of the Revised Piper Fatigue Scale in an Oncology Sample—A Rasch Analysis

Abstract: The current Rasch analyses add to the evidence of measurement properties of the scale and show that the RPFS has good psychometric properties and works well to measure fatigue. The original four-factor structure, however, was not supported.
