Does spouse participation influence quality of life reporting in patients with Parkinson’s disease?

Self-Report and Caregiver Proxy-Report Agreement of Perceived Chronic Stress and Mutuality in Poststroke Aphasia

Background People with aphasia (PWA) report higher levels of stress in comparison to stroke survivors without aphasia. If untreated, chronic stress is known to have detrimental effects to the body and brain and can negatively impact health and well-being. According to extant literature, self- and proxy-report agreement on objective domains is higher than on subjective domains, like chronic stress. In addition, high levels of mutuality, also known as shared feelings between two people, have been strongly associated with low levels of stress in stroke survivors. Little is known, however, of the agreement between self-report and caregiver proxy-report on perceived chronic stress or mutuality in PWA. Purpose The proposed study sought to examine (a) the degree of agreement between caregiver proxy-report and PWA self-report on perceived stress and (b) the relationship between perceived stress and mutuality between PWA and their caregivers. Method The Modified Perceived Stress Scale and the Mutuality Scale were administered to 21 PWA/caregiver dyads. An independent-samples t test was conducted to determine if there were significant differences in perceived stress and mutuality as reported by PWA, their caregiver, and their caregiver's proxy-report. A Pearson correlation was performed to determine the level of agreement across questionnaires. Results There was a moderate correlation between the proxy-report and self-report for perceived stress. On average, proxy-reports for perceived stress were significantly higher than PWA self-reports. Overall, mutuality was high among the dyads. There was moderate agreement between caregiver's mutuality and proxy-report agreement on perceived stress. Lastly, our findings do not indicate that caregiver's perceived stress influenced their perception of the PWA's perceived stress. Conclusion The results of this study provide support for the use of proxy-derived information in perceived stress with the use of a mutuality scale.

Factors associated with non-response at health-related quality of life follow-up in a septic shock trial

BACKGROUND

Follow-up of intensive care unit (ICU) patients often includes health-related quality of life (HRQoL) surveying, but non-responders hamper the interpretation. Our aim was to assess factors for non-response to HRQoL survey in ICU patients with septic shock at follow-up in a clinical trial.

METHODS

In a post hoc follow-up registry study, we assessed all the Danish survivors in the Transfusion-Requirements in Septic Shock trial patients, who were mailed the Short Form 36-item Survey (SF-36) 1-year after randomization. We used covariates from the trial database merged with covariates from nation-wide registries using the unique national identification number to explore possible factors for not responding. Five covariates were pre-specified to be included in the primary multivariate analysis: age, number of days in hospital from randomization to follow-up, level of education, cohabitation and employment status at follow-up. We compared the mortality from 1-year survival (2012-2014) till end of final follow-up (January 2016) between non-responders and responders.

RESULTS

We assessed 308 survivors of whom 108 (35%) were non-responders. In the primary analysis lower age (odds ratio 1.03, 95% CI [1.01-1.05]), more admission days in hospital (1.006 [1.001-1.011]) and living alone (4.33 [2.46-7.63]) were associated with non-responding, whereas the level of education and employment status were not. Non-responders had a hazard ratio of 1.63 [0.97-2.72] for mortality from 1-year follow-up to final follow-up as compared to the responders.

CONCLUSION

Being younger, spending more days in hospital and living alone were all associated with non-response at 1-year HRQoL follow-up among ICU patients with septic shock.

Mutuality and heart failure self-care in patients and their informal caregivers

BACKGROUND

Heart failure is a progressive condition characterized by frequent hospitalizations for exacerbated symptoms. Informal family caregivers may help patients improve self-care, which may in turn reduce hospitalizations. However, little is known about how mutuality, defined as the quality of the patient-caregiver relationship, and caregiver burden affect self-care.

OBJECTIVE

This study examines the associations among mutuality, patient self-care confidence (beliefs in abilities to engage in self-care behaviors) and maintenance (behaviors such as medication adherence, activity, and low salt intake), caregiver confidence in and maintenance of patient care, and caregiver perceived burden.

METHODS

This study used cross-sectional baseline data from a multi-site randomized clinical trial of a symptom and psychosocial care intervention. Patient-caregiver dyads ( N=99) completed self-report surveys of mutuality and self-care confidence and maintenance, and caregivers completed a measure of caregiver burden. Path analysis, with actor (effects within a person) partner (effects across the dyad) interdependence model paths and regression models were used to examine the associations among mutuality, caregiver burden, and self-care.

RESULTS

The majority of patients ( M age=66, 21% female) and caregivers ( M age=57, 81% female) were spouses (60%). The path model demonstrated significant actor effects; patients and caregivers with better mutuality were more confident in patient self-care ( p<.05). Partner effects were not significant. Regression models indicated that caregivers with greater mutuality reported less perceived burden ( p<.01).

CONCLUSIONS

Mutuality in patient-caregiver dyads is associated with patient self-care and caregiver burden and may be an important intervention target to improve self-care and reduce hospitalizations.

The factor structure of the Brief Symptom Inventory-18 (BSI-18) in Parkinson disease patients

OBJECTIVE

Psychological distress is common among Parkinson disease (PD) patients. Screening tools, such as the Brief Symptom Inventory-18 (BSI-18), help clinicians to identify and manage PD patients with psychiatric symptoms. The objective of this study is to test the factor structure of the BSI-18 in PD patients.

METHODS

Analysis was conducted on PD patients who had initial visits at a movement disorders center from 2004 to 2015. Univariate analysis was used to describe the distribution of socio-demographic and clinical characteristics. The BSI-18 was used to determine the prevalence of clinically significant psychological distress. Confirmatory factor analyses (CFA) treating BSI-18 items as ordered categorical data were conducted. Five competing models were tested. Multiple fit indices, parsimony, and past theory were used to select the final model.

RESULTS

In the study sample (n=1067), 18.7%, 22.5%, 15.4%, and 15.0% of patients had BSI-18 T-scores indicative of clinically significant global psychological distress, somatization, depression, and anxiety, respectively. Of the competing models, the final model chosen was the second-order three-factor structure with somatization, depression, and anxiety loaded on psychological distress.

CONCLUSION

The original proposed factor structure of the BSI-18 was validated in this patient population. Consequently, this study confirms the construct validity of the BSI-18 for screening of psychological distress in PD patients. Findings highlight somatization as a particularly important component of psychological distress in PD patients.

Determinants of Dyadic Relationship and Its Psychosocial Impact in Patients with Parkinson's Disease and Their Spouses

The caregiver-care receiver relationship (mutuality) in Parkinson's disease (PD) and its association with motor and non-motors symptoms, health-related quality of life (HRQoL), and caregiver burden have not fully been investigated. The aim of our study was to explore if (1) the level of mutuality perceived by PD-patients and PD-partners differs, (2) different factors are associated with perceived mutuality by PD-patients and PD-partners, and (3) mutuality is associated with PD-patients health-related quality of life (HRQoL) and caregiver burden. We collected data on motor signs (UPDRS III), non-motor manifestations (NMSQuest), PD-patients' cognition (IQCODE), mutuality scale (MS), PD-patients' HRQoL (PDQ8), and caregiver burden (CB) from 51 PD dyads. Predictors were identified using multivariate regression analyses. Overall, the dyads rated their own mutuality as high with no significant difference between the dyads except for the dimension of reciprocity. PD-patients' MS score (p = .001) and NMSQuest (p ≤ .001) were significant predictors of PDQ8. Strongest predictor of CB was PD-partners' MS score (<.001) and IQCODE (p = .050). In general, it seems that non-motor symptoms contribute to a larger extent to the mutual relationship in PD-affected dyads than motor disabilities.

Perceptions of Health-Related Quality of Life: A Minority Men's Perspective

Health-related quality of life (HRQOL) measures among the African American populations have previously been inadequately studied. This study sought to further analyze the quality of life of African American men at the Cleveland Clinic Minority Men's Health Center and Cleveland Clinic Minority Men's Health Fair. Subjects were randomly selected at the Minority Health Fair and Minority Men's Health Center clinics over the duration of 2 weeks to participate in the anonymous survey with the help of independent surveyors. Convenience sampling was done at the Minority Men's Health Fair and at the Minority Men's Health Clinics. Participants were administered in-person Short Form-36 (SF-36v2). A total of 83 participants were surveyed, and the response rate from the surveyed population was 100%. The only exclusion criterion for the study was the refusal to participate ( n = 0). As compared with healthy U.S. norms, African American men reported lower HRQOL across six health domains: physical functioning (60.69 ± 2.82 vs. 84.2), general health (57.56 ± 2.41 vs. 72), social functioning (72.65 ± 3.17 vs. 83.3), role-emotional (55.89 ± 3.02 vs. 81.3), mental health (61.23 ± 2.34 vs. 74.7), and role-physical (62.5 ± 2.88 vs. 81). The largest difference between the health domains was reported in role limitations due to emotional problems (55.89 ± 3.02 vs. 81.3, 25.4). Marital analysis revealed clinically significant lower HRQOL in married African Americans as compared with nonmarried, statistically significant in physical functioning and physical health component ( p < .05). African Americans disproportionally face pervasive disparities in health, as supported by extensive quality of life impairment. No other study, to our knowledge, has used quality of life assessment in African Americans to quantitate how such disparities are affecting important domains in their lives.
