- OBJECTIVE: This study aimed to investigate the psychometric properties of the General Self-Efficacy Scale (GSE) in people with Parkinson's disease (PD). More specifically, we investigated data completeness, scaling assumptions, targeting, reliability, and construct validity.MATERIALS AND METHODS: This study involves data available from two different projects that included people diagnosed with PD for at least 1 year, yielding two samples (1 and 2). The combined total sample (N = 346; 60% men) had a mean (SD) age and PD duration of 71 (8.9) and 9 years (6.3), respectively. Both samples received a self-administered survey by mail, which was administered twice in sample 2. Additional data (e.g., clinical assessments) were available for Sample 1.RESULTS: Total GSE scores were computable for 336 participants (97%). Corrected item-total correlations exceeded 0.4. Principal component analyses identified one component (the eigenvalue of the first component extracted was 6.9), explaining 69% of the total variance. Floor and ceiling effects were < 6%. Internal consistency (coefficient alpha) was 0.95. Analyses of test-retest reliability yielded (ICC) values from 0.69 to 0.80. The highest value refers to those (n = 47) with identical self-ratings of mobility (in the on condition) at both tests; the standard error of measurement was 3.1 points. Construct validity was further supported by correlations in accordance with a priori expectations.CONCLUSIONS: This study provides support for the validity and reliability of GSE scores in people with PD; the GSE can thus serve as a valuable outcome measurement in clinical practice and research.

- Objective: The objective of this paper is to describe the initial phase of a long-term collaboration initiative between a municipality and the Faculty of Medicine at a university in Sweden. The overall ambition of the collaboration is to strengthen the quality of care for older people. The concrete goal is to equip academically trained registered health care professionals (HCP) with tools for transferring evidence-based knowledge into practice. As municipal healthcare for older people is mainly carried out by staff lacking academic education, reg. HCP are key actors to bring in and consolidate an evidence-based approach in this setting. Developmental evaluation (DE) has been used to evaluate four separate activities in the initial phase. The activities where sequenced in a cumulative design to provide knowledge for further development of adequate tools.Results: The cumulative design originally planned did not fit the internal logic of the municipality. Therefore, workflow and pace adjustments were made to proceed towards the joint ambition; the creation of fruitful conditions for the uptake of evidence-based knowledge. Long-term collaboration between academia and organizations outside academia demands a sensitive and flexible research approach, recognizing that collaboration implies mutuality and restricts the sovereignty of academia in designing research.

- Introduction. People with Parkinson's disease (PD) have lower life satisfaction (LS) than healthy peers. No study has yet identified predictors of LS in people with PD. Such information would be valuable for health care and future interventions that aim to maintain or increase LS. Aim. To examine how LS evolved in people with PD over a 3-year period, as well as to identify predictive factors of LS. Methods. We used data from baseline assessments and a 3-year follow-up of 163 people with PD (baseline, mean age 68 years; median PD duration 8 years, 35% women). LS was assessed with item 1 of the Life Satisfaction Questionnaire (LiSat-11). Dichotomized LS data from the 3-year follow-up were used as the dependent variable in multivariable logistic regression analyses. In the first step, independent variables included baseline information on sex, education, general self-efficacy, motor symptoms, perceived walking difficulties, fall-related activity avoidance, and difficulties with/need help in activities of daily living. At the second step, depressive symptoms were added as an independent variable. Results. The proportion of those who reported being satisfied with their lives reduced from 63.2% at baseline to 49.7% 3 years later (p=0.003). When depressive symptoms were not included in the analysis, general self-efficacy (odds ratio, OR = 1.081; 95% CI = 1.019-1.147) and perceived walking difficulties (OR = 0.962; 95% CI = 0.929-0.997) were significant (p<0.05) predictors of LS 3 years later. With depressive symptoms included, the influence of walking difficulties diminished, and depressive symptoms (OR = 0.730; 95% CI = 0.607-0.877) and general self-efficacy (OR = 1.074; 95% CI = 1.010-1.142) were the only significant predictors of LS 3 years later. Conclusions. LS is reduced over a 3-year period. The study suggests that perceived walking difficulties, general self-efficacy, and depressive symptoms are important predictors of LS in people with PD.

- Although fear of falling (FOF) is common in people with Parkinson's disease (PD), there is a lack of research investigating potential predictors of FOF. This study explored the impact of motor, nonmotor, and demographic factors as well as complications of drug therapy on FOF among people with PD. Postal survey data (including the Falls Efficacy Scale, FES) from 154 nondemented people with PD were analyzed using multiple regression analyses. Five significant independent variables were identified explaining 74% of the variance in FES scores. The strongest contributing factor to FOF was walking difficulties (explaining 68%), followed by fatigue, turning hesitations, need for help in daily activities, and motor fluctuations. Exploring specific aspects of walking identified three significant variables explaining 59% of FOF: balance problems, limited ability to climb stairs, and turning hesitations. These results have implications for rehabilitation clinicians and suggest that walking ability is the primary target in order to reduce FOF. Specifically, balance, climbing stairs, and turning seem to be of particular importance.

- Objective: To evaluate a set of psychometric properties (i.e., data completeness, targeting andexternal construct validity) of the Parkinson’s disease Activities of Daily Living Scale (PADLS) in people with Parkinson’s disease (PD). Specific attention was paid to the association between PADLS and PD severity, according to the Hoehn & Yahr (H&Y) staging. Methods: The sample included 251 persons with PD (mean age 70 [SD 9] years). The data collection comprised a self-administered postal survey, structured interviews and clinical assessments at home visits. Results: Data completeness was 99.6% and the mean PADLS score was 2.1. Floor and ceiling effects were 22% and 2%, respectively. PADLS scores were more strongly associated (rs>0.5) with perceived functional independence, dependence in ADL, walking difficulties and self- rated PD severity than with variables such as PD duration and cognitive function (rs<0.5).PADLS scores differed across H&Y stages (Kruskal-Wallis test, p<0.001). Those in H&Y stages IV-V had more ADL disability than those in stage III (Mann-Whitney U-test, p<0.001), whereas there were no significant differences between the other stages. Conclusion: The PADLS revealed excellent data completeness, acceptable targeting and external construct validity. It seems to be well suited as a rough estimate of ADL disability inpeople with PD.

Objective Observer vs. Patient Motor State Assessments Using the PD Home Diary in Advanced Parkinsons Disease
- 2022
-
Ingår i: Frontiers in Neurology. - : Frontiers Media SA. - 1664-2295. ; 13
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The Parkinson Disease (PD) Home Diary (HD) is a commonly used clinical outcome measure, but it has not been extensively compared to direct assessments by experienced observers. Objective: Validation of patient-reported HD by investigating the agreement between motor state assessments by patients and observers. Methods: This observational study included patients with PD and motor fluctuations. Observers were physicians or research nurses. Patients completed a screening visit, one day of diary ratings at home, and then two days of ratings on-site during which patients and observers simultaneously judged the participants motor state. Results: Observers and 40 patients completed 1,288 pairs of half-hourly blinded motor state assessments. There were significant differences between observer and patient ratings (P < 0.001) and the temporal agreement was poor (Cohens kappa = 0.358). The agreement between patient and observer ratings was 71.1% for observed "On without dyskinesia", 57.3% for observed "Off", and 49.4% for observed "On with dyskinesia". Daily times spent in the three motor states as aggregated diary data showed fair to excellent reliability with intraclass coefficient values ranging from 0.45 to 0.52 for "On" and 0.77 for "Off". Conclusion: There were significant differences between observer and patient ratings. Patients and observers generally agreed on when the patients was in the "On" state (with or without dyskinesia). Patient ratings on the hour level seem to be influenced by other aspects of the patients experience than the observed motor state, but assessment of daily time spent in the different motor state provides reasonable reliability.

Time to workforce exit after a Parkinsons disease diagnosis
- 2023
-
Ingår i: NPJ PARKINSONS DISEASE. - : NATURE PORTFOLIO. - 2373-8057. ; 9:1
-
Tidskriftsartikel (refereegranskat)abstract
- The impact of Parkinsons disease (PD) on workforce participation has received little attention even though demographic, lifestyle, and political changes together will result in an increased burden of PD on the working-age population. In this study, we investigate workforce survival after a PD diagnosis, as well as what demographic factors that are associated with workforce survival. As an exploratory outcome, we investigate workforce survival in persons with and without device-aided treatment (DAT). This is a nested case-cohort study based on Swedish national data from 2001-2016. Controls were matched on year of birth, sex, and municipality of residence. The used registers contain data on demographics, social insurance, in- and outpatient visits, filled drug prescriptions, and cause of death on the person-level. A total of 4781 persons with PD and 23,905 controls were included. The median survival until all-cause workforce exit was 43 months among persons that were workforce-active at the time of PD diagnosis, compared to 66 months in non-PD controls. Being female, >= 50 years old at diagnosis, or having a lower education were contributing factors to health-related workforce exit. Persons receiving DAT during follow-up exhibited shorter workforce survival than controls. However, this needs further investigation, particularly as patients have generally already left the workforce at the time for start of DAT. It is evident that PD has grave negative effects on workforce participation. Thus, supportive measures need to start at an early stage after diagnosis, and the development of new interventions is urgently needed.

Tidskriftsartikel (refereegranskat)abstract
- The importance of understanding the prodromal phase of Parkinson’s disease (PD) by systematic recording of prediagnostic symptoms and reductions in body functions has been highlighted. The aim of this study was to investigate whether persons later diagnosed with PD exhibit increased physician-certified sickness absence 1, 2, and 5 years prior to a first sick-leave episode attributed to PD. A case-control study was performed to analyze data from all nontrivial (exceeding 14 days) sick-leave episodes in Sweden between 2008 and 2014. The 537 incident PD sick-leave episodes were identified as PD sick-leave cases and compared to 537 sick-leave controls identified by matching age, sex, and date of the first day of the sick-leave episode. The total sickness absence and sickness absence due to musculoskeletal diagnoses were found to be increased among the PD sick-leave cases from 5 years prior to the first sick-leave episode ascribed to PD when compared to the controls. No differences between PD sick-leave cases and sick-leave controls were found with regard to mental and behavioral diagnoses. We conclude that the capacity to participate in working life is reduced already at the early prediagnostic stages of PD. This finding can be used as a basis for further research into the process of identifying individuals at risk for developing PD, particularly in combination with further investigation into biochemical, genetic, and imaging biomarkers.

Satisfaction with care in late stage Parkinson’s disease
- 2019
-
Ingår i: Parkinson's Disease. - 2090-8083 .- 2042-0080. ; 2019
-
Tidskriftsartikel (refereegranskat)abstract
- In late stage Parkinson’s disease (PD) (i.e., Hoehn and Yahr (HY) stages IV-V), both motor and nonmotor symptoms (NMS) are pronounced, and the patients become increasingly dependent on help in their daily life. Consequently, there is an increasing demand on health-care and social care resources for these patients and support for their informal caregivers. The aim of this study was to assess satisfaction with care in late stage PD patients and to identify factors associated with satisfaction with care. Moreover, to assess their informal caregivers’ satisfaction with support and to identify factors associated with caregivers’ satisfaction with support. Factors potentially associated with satisfaction with care/support were assessed in 107 late stage PD patients and their informal caregivers () and entered into multivariable logistic regression analyses. Fifty-eight (59%) of the patients and 45 (59%) of the informal caregivers reported satisfaction with their overall care/support. Patients satisfied with their care reported higher independence in activities of daily living (ADL) (Katz ADL index; ), less depressive symptoms (Geriatric Depression Scale, GDS-30; ), and higher individual quality of life (QoL) (Schedule for the Evaluation of Individual Quality of Life Questionnaire, SEIQoL-Q; ). Multivariable logistic regression analyses identified depressive symptoms () and independence in ADL () as independently associated with satisfaction with care. For informal caregivers, the analyses identified patients’ HY stage () and caregivers’ QoL (Alzheimer’s Carers Quality of Life Inventory, ACQLI; ) as independently associated with satisfaction with caregiver support. The results indicate that an effective both pharmacological and nonpharmacological PD therapy is important, to adequately treat motor and NMS (e.g., depressive symptoms) in order to improve depressive symptoms and patient independence in ADL. This may benefit not only the patients, but also their informal caregivers.

Dopaminergic effect on non-motor symptoms in late stage Parkinson's disease
- 2018
-
Ingår i: Journal of Parkinson's Disease. - : IOS Press. - 1877-7171 .- 1877-718X. ; 8:3, s. 409-420

Tidskriftsartikel (refereegranskat)abstract
- Background: Non-motor symptoms (NMS) are common in late stage Parkinson's disease (PD), as the frequency and severity of most of these symptoms increase with advancing disease. Objective: To assess effect of dopaminergic therapy on NMS in late stage PD and to investigate relationships between dopaminergic effect on NMS and on motor function. Method: Thirty PD patients in Hoehn and Yahr (HY) stages IV and V in "on" were included. Dopaminergic effect on non-motor symptomatology was assessed by the modified version of the Non-Motor Symptoms Scale (NMSS) in the "off" and the "on" state during a standardized L-dopa test, in parallel also assessing motor function. Results: NMS were common and many of the symptoms occurred in>80% of the individuals. The highest NMSS scores were seen within the NMSS domains 3: mood/apathy and 7: urinary in both the "off" and the "on" state. There was a statistically significant (p<0.001) improvement in the modified NMSS total score (median) from 79 in "off" to 64 in "on". There were statistically significant differences between the "off" and the "on" state for domains 2: sleep/fatigue, 3: mood/apathy, 5: attention/memory, 6: gastrointestinal and 7: urinary. The differences in the NMSS score between the "off" and the "on" state were in general larger for motor responders than for motor non-responders. In motor non-responders, differences of the NMSS score between the "off" and the "on" state were found for the total score, domain 3: mood/apathy and its item 11-flat moods. Conclusion: There is an effect of dopaminergic medication on NMS in late stage PD, to some extent also for those with a non-significant response on motor function during L-dopa test. It is therefore of importance to optimize dopaminergic therapy in order to give the most effective symptomatic treatment possible.
