In: Journal of the Acoustical Society of America. - : Acoustical Society of America (ASA). - 0001-4966 .- 1520-8524. ; 147:2, s. 839-851

Journal article (peer-reviewed)abstract
- This investigation aimed at determining whether an acoustic quantification of the oral diadochokinetic (DDK) task may be used to predict the perceived level of speech impairment when speakers with Parkinson's disease (PD) are reading a standard passage. DDK sequences with repeated [pa], [ta], and [ka] syllables were collected from 108 recordings (68 unique speakers with PD), along with recordings of the speakers reading a standardized text. The passage readings were assessed in five dimensions individually by four speech-language pathologists in a blinded and randomized procedure. The 46 acoustic DDK measures were merged with the perceptual ratings of read speech in the same recording session. Ordinal regression models were trained repeatedly on 80% of ratings and acoustic DDK predictors per dimension in 10-folds, and evaluated in testing data. The models developed from [ka] sequences achieved the best performance overall in predicting the clinicians' ratings of passage readings. The developed [pa] and [ta] models showed a much lower performance across all dimensions. The addition of samples with severe impairments and further automation of the procedure is required for the models to be used for screening purposes by non-expert clinical staff.

Psychometric properties of the EQ-5D-5L in patients with knee or hip osteoarthritis : confirmatory factor analysis and item response theory
- 2024

In: Osteoarthritis and Cartilage. - 1063-4584. ; 32:Suppl 1, s. 196-197

Conference paper (peer-reviewed)abstract
- Purpose (the aim of the study): There is limited evidence on psychometric properties of EQ-5D-5L among people with osteoarthritis (OA) undertaking non-surgical treatment. The aim of the current study was to evaluate the psychometric properties of the EQ-5D-5L among individuals with knee or hip OA participating in a digitally delivered education and exercise therapy.Methods: Secondary analysis of data obtained from individuals aged 40+ years participating in the digital treatment during the year 2021 with the responses to EQ-5D-5L at enrolment. Confirmatory factor analysis (CFA) with the weighted least square mean and variance adjusted estimator was used to assess dimensionality. Local independency assumption was assessed using residual correlations between item pairs with r>0.2 as violation of the assumption. Monotonicity was evaluated using Mokken analysis. Item response theory was implemented by generalized partial credit model. The item parameters (discrimination and difficulty) were estimated using the maximum marginal likelihood estimation. Targeting was assessed by inspecting the item-person map (the Wright map). Differential item functioning (DIF) by sex, age (≤65 years vs. >65 years) and OA site (knee vs. hip) were assessed and items with a McFadden pseudo-R2 change of ≥0.02 were flagged for potential DIF. All analyses were conducted in RStudio version 2022.02.0.Results: A total of 16,200 individuals with mean (standard deviation) age 64.3 (9.1), 74.0% females and 59.6% with knee OA were included. The included subjects reported 609 of the 3,125 possible health profiles of the EQ-5D-5L with slight or moderate problems with pain/discomfort dimension and no problems on the other dimensions (i.e. profiles “11121” and “11131”) being the first and second most common profiles (9.4% and 4.4% of respondents, respectively). CFA confirmed the unidimensionality of the EQ-5D-5L with factor loading ranged from 0.49 for anxiety/depression to 0.85 for usual activity dimensions, and an average variance extracted of 0.53 suggesting adequate convergent validity. Local independence and monotonicity assumptions were met. The fit statistics suggested an adequate fit of IRT model. Among five dimensions, pain/discomfort was the most affected (least difficult to endorse) while self-care was the least affected (most difficult to endorse). No disordered response thresholds were identified. EQ-5D-5L showed adequate reliability (>0.7) over a wide range of the underlying trait (76.4% of total information were within -1 to 4 standard deviation of average level of poor HRQoL) with an overall reliability of 0.80 (Figure 1). Usual activity and anxiety/depression were the most and least informative items. Inspecting the item-person map (Figure 2) suggested that while EQ-5D-5L covered the full range of HRQoL levels in the sample, it targeted, on average, a poorer HRQoL than experienced by the participants in the study. No DIF (uniform or nonuniform) was detected.Conclusions: The EQ-5D-5L demonstrated acceptable psychometric properties among subjects with hip or knee OA participating in a digital education and exercise therapy. These results support the use of EQ-5D-5L among people with less severe knee or hip OA.

Self-reported symptom severity, general health, and impairment in post-acute phases of COVID-19: retrospective cohort study of Swedish public employees
- 2022
-
In: Scientific Reports. - : Springer Science and Business Media LLC. - 2045-2322. ; 12:1
-
Journal article (peer-reviewed)abstract
- This study aimed to examine current symptom severity and general health in a sample of primarily non-hospitalized persons with polymerase chain reaction (PCR) confirmed COVID-19 in comparison to PCR negative controls. During the first quarter of 2021, we conducted an online survey among public employees in West Sweden, with a valid COVID-19 test result. The survey assessed past-month severity of 28 symptoms and signs, self-rated health, the WHO Disability Assessment Schedule (WHODAS) 2.0 and illness severity at the time of test. We linked participants' responses to their SARS-CoV-2 PCR tests results. We compared COVID-19 positive and negative participants using univariable and multivariable regression analyses. Out of 56,221 invited, 14,222 (25.3%) responded, with a response rate of 50% among SARS-CoV-2 positive individuals. Analysis included 10,194 participants (86.4% women, mean age 45 years) who tested positive 4-12 weeks (N = 1425; subacute) and > 12 weeks (N = 1584; postcovid) prior to the survey, and 7185 PCR negative participants who did not believe that they had had COVID-19. Symptoms were highly prevalent in all groups, with worst symptoms in subacute phase participants, followed by postcovid phase and PCR negative participants. The most specific symptom for COVID-19 was loss of smell or taste. Both WHODAS 2.0 score and self-rated health were worst in subacute participants, and modestly worse in postcovid participants than in negative controls. Female gender, older age and acute illness severity had larger effects on self-rated health and WHODAS 2.0 score in PCR positive participants than in PCR negative. Studies with longer follow-up are needed to determine the long-term improvement after COVID-19.

Validation of Fatigue Impact Scale with various item sets – a Rasch analysis
- 2019

Journal article (peer-reviewed)abstract
- © 2017 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group Purpose: Fatigue is a symptom in patients with chronic gastrointestinal (GI) and liver diseases. Different instruments have been developed to assess the severity of fatigue and the 40-item Fatigue Impact Scale (FIS) is among the most widely used. Shorter versions of FIS include the 21-item Modified Fatigue Impact Scale (MFIS), and an eight-item version for everyday use. The study aimed to assess construct validity, reliability, and sufficiency of the raw score of the original FIS with 40 items, and examine the sufficiency of the 21 items from the Modified scale and the eight items of the Daily Fatigue Impact Scale (D-FIS), all of which are embedded in the 40-item scale. Methods: Patients with chronic GI or liver disease (n=354) completed the FIS with 40 items. The majority (57%) was under the age of 55years and approximately half were females (48%). Various item sets of FIS were derived which showed fit to the Rasch model. Results: Local dependency and multidimensionality in FIS and the 21-item Modified scale were resolved with a testlet solution but the D-FIS showed local dependency and multidimensionality and differential item functioning (DIF) still remained. Two new item sets fulfilling unidimensionality and no DIF are suggested, one with 15 items and a six-item scale for daily use. The transformation table shows score-interval scale estimates for all these item sets. Conclusions: Both the FIS and the Modified scale can be used to measure fatigue albeit requiring some adjustment for DIF. The eight-item D-FIS is more problematic, and its summed score is not valid. Alternative 15- and 6-item versions presented in this paper can offer valid summed scores, and the transformation table allows transformation of raw scores and comparisons across all versions.Implications for rehabilitationThe Fatigue Impact Scale and the Modified Fatigue Impact Scale can be used to measure fatigue after adjustments for differential item functioning.Alternative 15- and 6-item versions of Fatigue Impact Scale offer valid summed scores. The summed score for the Daily Fatigue Impact Scale is not valid.A transformation table with raw scores and Rasch transformed interval scale metric makes it possible to compare scores derived from the Fatigue Impact Scale, the Modified Fatigue Impact Scale and the proposed 15- and 6-item versions of Fatigue Impact Scale for research and/or clinical use.

To come home after a stroke: patients' early experiences of health and recovery in their home settings
- 2018
-
Conference paper (other academic/artistic)abstract
- Healthcare systems and services for stroke patients are increasingly performed within home settings where both, people with moderate and severe disability can receive care. However, at present little knowledge is available in regard to early stroke phases and how the interaction with the physical environment of home settings might affect rehabilitation outcomes. The aim of this work was thus, to increase our understanding in regard to the interplay between home settings and people’s rehabilitation process, a month after stroke onset. A cross-sectional interdisciplinary investigation was conducted using validated measures in face-to-face interviews and by observing the participants’ interactions with their home settings. People with stroke (N = 16) that had a mild disability, and cognitive and communicative abilities to participate in an interview of approximately 2 hours, were recruited in the study and their data was collected within 4 to 7 weeks after stroke onset. Information was collected in regard to their experience of the physical and social home environment, their attachment to place, self-efficacy and the quality of continuity of care from the hospital to the home. Moreover, data about their recovery and overall health were collected with, Stroke Impact Scale and the EQ-5D. Preliminary results suggests the existence of a relation between recovery levels, self-efficacy and the perceived quality of the physical environment of home settings. More detailed results and their implication for early rehabilitation phases of stroke patients within home settings will be discussed.

Detection of subclinical motor speech deficits after presumed low-grade glioma surgery
- 2023
-
In: Brain Sciences. - : MDPI. - 2076-3425. ; 13:12
-
Journal article (peer-reviewed)abstract
- Motor speech performance was compared before and after surgical resection of presumed low-grade gliomas. This pre- and post-surgery study was conducted on 15 patients (mean age = 41) with low-grade glioma classified based on anatomic features. Repetitions of /pa/, /ta/, /ka/, and /pataka/ recorded before and 3 months after surgery were analyzed regarding rate and regularity. A significant reduction (6 to 5.6 syllables/s) pre- vs. post-surgery was found in the rate for /ka/, which is comparable to the approximate average decline over 10–15 years of natural aging reported previously. For all other syllable types, rates were within normal age-adjusted ranges in both preoperative and postoperative sessions. The decline in /ka/ rate might reflect a subtle reduction in motor speech production, but the effects were not severe. All but one patient continued to perform within normal ranges post-surgery; one performed two standard deviations below age-appropriate norms pre- and post-surgery in all syllable tasks. The patient experienced motor speech difficulties, which may be related to the tumor’s location in an area important for speech. Low-grade glioma may reduce maximum speech-motor performance in individual patients, but larger samples are needed to elucidate how often the effect occurs.

Professional´s skills in assment of perineal tears after childbirth - a systematic review
- 2013
-
In: Open Journal of Obstetrics and Gynecology. - 2160-8792 .- 2160-8806. ; 2013:3, s. 7-15

Journal article (peer-reviewed)abstract
- Perineal tears are one of the most common complications of vaginal births and may cause discomfort and pain long time after childbirth. Visual and digital examination of perineal tears is the most common way to assess and classify a perineal tear. Recent research indicates that many tears diagnosed are misclassified. The aim of this systematic literature review was to outline research that investigates healthcare professionals’ clinical knowledge in assessment and classification of perineal tears in connection with childbirth. Searches were performed in PubMed and CINAHL. Six studies on the topic were identified and used to collect data for questionnaires. An integrative review was used in the analysis. Poor knowledge in perineal anatomy and lack of training in clinical assessment and classification of perineal trauma was evident among both physicians and midwives. These findings indicate that healthcare providers lack adequate knowledge and that they make incorrect assessments and errors in classification of perineal tears. The training in assessment and classification is crucial. Midwives are in a unique position to improve the standard of care in this field since they are often the first and many times the only to assess the injury.

A structural equation model of the relation between socioeconomic status, physical activity level, independence and health status in older Iranian people
- 2017

Journal article (peer-reviewed)abstract
- Background and aim: Health status is an independent predictor of mortality, morbidity and functioning in older people. The present study was designed to evaluate the link between socioeconomic status (SES), physical activity (PA), independence (I) and the health status (HS) of older people in Iran, using structural equation modelling. Methods: Using computerized randomly selection, a representative sample of 851 75-year-olds living in Tehran (2007-2008), Iran, was included. Participants answered questions regarding indicators of HS, SES and also PA and I through interviews. Both measurement and conceptual models of our hypotheses were tested using Mplus 5. Maximum-likelihood estimation with robust standard errors (MLR estimator), chisquare tests, the goodness of fit index (and degrees of freedom), as well as the Comparative Fit Index (CFI), and the Root Mean Square Error of Approximation (RSMEA) were used to evaluate the model fit. Results: The measurement model yielded a reasonable fit to the data, chi(2) = 110.93, df = 38; CFI = 0.97; RMSEA = 0.047, with 90% C.I. = 0.037-0.058. The model fit for the conceptual model was acceptable; chi(2) = 271.64, df = 39; CFI = 0.91; RMSEA = 0.084, with 90% C.I. = 0.074-0.093. SES itself was not a direct predictor of HS (beta = 0.13, p = 0.059) but it was a predictor of HS either through affecting PA (beta = 0.31, p < 0.001) or I (beta = 0.57, p < 0.001). Conclusion: Socioeconomic status appeared to influence health status, not directly but through mediating some behavioral and self-confidence aspects including physical activity and independence in ADL.

Fatigue in Parkinson's Disease: Measurement Properties of a Generic and a Condition-specific Rating Scale.
- 2013
-
In: Journal of Pain and Symptom Management. - : Elsevier BV. - 1873-6513 .- 0885-3924. ; 46:5, s. 737-746

Journal article (peer-reviewed)abstract
- CONTEXT: High-quality fatigue rating scales are needed to advance the understanding of fatigue and determine the efficacy of interventions. Several fatigue scales are used in Parkinson's disease, but few have been tested using modern psychometric methodology (Rasch analysis). OBJECTIVES: To examine the measurement properties of the generic Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale and the condition-specific 16-item Parkinson Fatigue Scale (PFS-16) using Rasch analysis. METHODS: Postal survey data (n=150; 47% women; mean age 70 years) were Rasch analyzed. The PFS-16 scores were tested according to both the original polytomous and the suggested alternative dichotomized scoring methods. RESULTS: The PFS-16 showed overall Rasch model fit, whereas the FACIT-F showed signs of misfit, which probably was the result of a sleepiness-related item and mixing of positively/negatively worded items. There was no differential item functioning by disease duration but by fatigue status (greater likelihood of needing to sleep or rest during the day among people classified as nonfatigued) in the PFS-16 and FACIT-F. However, this did not impact total score-based estimated person measures. Targeting and reliability (≥0.86) were good, but the dichotomized PFS-16 showed compromised measurement precision. Polytomous and dichotomized PFS-16 and FACIT-F scores identified six, three, and four statistically distinct sample strata, respectively. CONCLUSION: We found general support for the measurement properties of both scales. However, polytomous PFS-16 scores exhibited advantages compared with dichotomous PFS-16 and FACIT-F scores. Dichotomization of item responses compromises measurement precision and the ability to separate people, and should be avoided.
