Several studies have documented the variety of post-stroke psychosocial challenges, which are complex, multifaceted, and affect a patient’s rehabilitation and recovery. Due to the consequences of these challenges, psychosocial well-being should be considered an important outcome of the stroke rehabilitation. Thus, a valid and reliable instrument that is appropriate for the stroke population is required. The factor structure of the Norwegian version of GHQ-28 has not previously been examined when applied to a stroke population. The purpose of this study was to explore the psychometric properties of the GHQ-28 when applied in the stroke population included in the randomized controlled trial; “Psychosocial well-being following stroke”, by evaluating the internal consistency, exploring the factor structure, construct validity and measurement invariance. Data were obtained from 322 individuals with a stroke onset within the past month. The Kaiser-Meyer-Olkin (KMO) test was used to test the sampling adequacy for exploratory factor analysis, and the Bartlett’s test of sphericity was used to test equal variances. Internal consistency was analysed using Cronbach’s alpha. The factor structure of the GHQ-28 was evaluated by exploratory factor analysis (EFA), and a confirmatory factor analysis (CFA) was used to determine the goodness of fit to the original structure of the outcome measurement. Measurement invariance for two time points was evaluated by configural, metric and scalar invariance. The results from the EFA supported the four-factor dimensionality, but some of the items were loaded on different factors compared to those of the original structure. The differences resulted in a reduced goodness of fit in the CFA. Measurement invariance at two time points was confirmed. The change in mean score from one to six months on the GHQ-28 and the factor composition are assumed to be affected by characteristics in the stroke population. The results, when applying the GHQ-28 in a stroke population, and sub-factor analysis based on the original factor structure should be interpreted with caution.

Purpose: To (1) identify interventional research topics in traumatic brain injury (TBI) rehabilitation, (2) describe potential knowledge gaps, and (3) uncover further needs for interventional TBI rehabilitation research for patients and families. Method: We searched three databases (2006–2019) and screened 1552 non-duplicate articles. Titles and abstracts were screened for relevance, yielding 754 articles for full-text review. Of these, 425 were included, as relevant to the purpose of the scoping review. Findings: Among articles on TBI rehabilitation, the majority (71.8%) applied quantitative methodology; of these only 19.7% were randomized controlled trials. Severe TBI was described more often than mild/moderate TBI populations. Hospital vs community/home rehabilitation was 55.1% vs 37.2%; rehabilitation at workplace/school was described in only 4.5% articles, while in 7.2% the setting was undisclosed. Of 83 articles describing work/education, only 14 were in a work/school context. An additional focus in the work/education articles was activities of daily living (n = 28), cognition (n = 33) and emotions (n = 23), few targeted family or network. Conclusion: The main attention of interventional TBI rehabilitation studies has been on severe TBI and long-term rehabilitation. Gaps identified were rehabilitation of mild/moderate TBI populations, older populations, acute/sub-phase rehabilitation, return to work issues and studies including the family.
Objective: This study investigated the validity, reliability, responsiveness, and interpretability of the Patient-Specific Functional Scale (PSFS) in subacute stroke rehabilitation to determine its suitability to measure patient-identified rehabilitation goals. Methods: A prospective observational study was designed according to the checklist from Consensus-Based Standards for Selecting Health Measurement Instruments. Seventy-one patients diagnosed with stroke were recruited in the subacute phase from a rehabilitation unit in Norway. The International Classification of Functioning, Disability and Health was used to assess the content validity. Assessment of construct validity was based on hypotheses for correlation of the PSFS and comparator measurements. We assessed reliability by calculating the Intraclass Correlation Coefficient (ICC) (3.1) and the standard error of measurement. The assessment of responsiveness was based on hypotheses for the correlation of change scores between the PSFS and the comparator measurements. A receiver operating characteristic analysis was conducted to assess responsiveness. The smallest detectable change and minimal important change were calculated. Results: Eighty percent of the PSFS items were classified as activities and participation in the International Classification of Functioning, Disability and Health, indicating satisfactory content validity. The reliability was satisfactory with an ICC of 0.81 (95% CI = 0.69–0.89). The standard error of measurement was 0.70 point, and the smallest detectable change was 1.94 points. Five of 7 hypotheses were confirmed for construct validity, and 5 of 6 were confirmed for responsiveness, indicating moderate construct validity and high responsiveness. Assessing responsiveness with a criterion approach resulted in an area under the curve of 0.74. A ceiling effect was identified for 25% of the participants 3 months after discharge. The minimal important change was estimated to be 1.58 points. Conclusion: This study demonstrates satisfactory measurement properties for the PSFS in individuals undergoing inpatient stroke rehabilitation. Impact: This study supports the use of the PSFS to document and monitor patient-identified rehabilitation goals in patients receiving subacute stroke rehabilitation when applied using a shared decision approach.

Background: Fatigue is a common symptom associated with a wide range of diseases and needs to be more thoroughly studied. To minimise patient burden and to enhance response rates in research studies, patient-reported outcome measures (PROM) need to be as short as possible, without sacrificing reliability and validity. It is also important to have a generic measure that can be used for comparisons across different patient populations. Thus, the aim of this secondary analysis was to evaluate the psychometric properties of the Norwegian 5-item version of the Lee Fatigue Scale (LFS) in two distinct patient populations. Methods: The sample was obtained from two different Norwegian studies and included patients 4–6 weeks after stroke (n = 322) and patients with osteoarthritis on a waiting list for total knee arthroplasty (n = 203). Fatigue severity was rated by five items from the Norwegian version of the LFS, rating each item on a numeric rating scale from 1 to 10. Rasch analysis was used to evaluate the psychometric properties of the 5-item scale across the two patient samples. Results: Three of the five LFS items (“tired”, “fatigued” and “worn out”) showed acceptable internal scale validity as they met the set criterion for goodness-of-fit after removal of two items with unacceptable goodness-of-fit to the Rasch model. The 3-item LFS explained 81.6% of the variance, demonstrated acceptable unidimensionality, could separate the fatigue responses into three distinct severity groups and had no differential functioning with regard to disease group. The 3-item version of the LFS had a higher separation index and better internal consistency reliability than the 5-item version. Conclusions: A 3-item version of the LFS demonstrated acceptable psychometric properties in two distinct samples of patients, suggesting it may be useful as a brief generic measure of fatigue severity.

Background: Bachelor students of occupational therapy are expected to work in accordance with evidence-based practice (EBP). The EBP work file, a learning tool in a Word document format, covering all steps in the EBP process, is an approach to teaching and learning EBP. The aim of this study was to examine the attitudes and behaviours of occupational therapy students’ in relation to applying evidence-based practice during their second-year clinical placement. We compared cohorts who received training in EBP work files with those who did not receive such training. Methods: A descriptive, cross-sectional comparative study was conducted. Five cohorts of second-year occupational therapy students took part in the study. The students answered two questionnaires, the EBP Beliefs Scale and the EBP Implementation Scale, after completing their second-year clinical placement. The analysis was based on descriptive statistics and calculation of the frequencies, percentages, mean and standard deviations of all participating students’ scores across both questionnaires. ANOVA with Bonferroni correction was conducted to analyse the differences between the mean totals of the questionnaires. Results: In this study, 126 occupational therapy students participated (response rate = 57.3%). The students reacted positively to EBP, although few were practicing EBP. The students believed that EBP resulted in the best clinical care for patients, but they lacked confidence in their own ability to apply EBP. The students in Cohort 5, who received extra instruction and assignments via the EBP work file, rated their EBP behaviour statistically lower than the students in Cohort 1, who did not receive extra training on the EBP work file. Conclusions: Additional EBP work file assignments were insufficient in terms of supporting students in the implementation of EBP during clinical placements. It is, therefore, important to facilitate the learning strategies of EBP skills and demonstrate how students can practise this competency during clinical placements. Including clinical instructors in EBP teaching and learning seems essential.
