How Is Quality of Life Assessed in People With Dementia? A Systematic Literature Review and a Primer for Speech-Language Pathologists

Achieving consensus on assessing health-related quality of life (HRQoL) in people with cognitive impairments (CI)a Delphi study

BACKGROUND

The prevalence of impairments of cognitive functions is expected to increase. Enhancing the QoL of those affected is important. HRQoL in people with CI can be assessed by self-report, proxy-report or observation but there is uncertainty how to best assess HRQoL in people with CI, and which assessment method is most appropriate. Therefore the aim of our study was to use Delphi methodology in order to achieve consensus on how HRQoL should be assessed in people with CI and which content domains should be assessed.

METHODS

The Delphi process consisted of three online survey rounds and a concluding consensus conference. Participants were experts as well as individuals and relatives of people affected by CI. The Delphi survey was developed based on existing literature and included 55 statements at the first round. Consensus was considered to be achieved when a minimum of 75 % of responses fell into the categories 6 (agree) and 7 (strongly agree) (positive consensus) or in categories 1 (strongly disagree) and 2 (disagree) (negative consensus).

RESULTS

Consensus was reached for a total of 41 of 56 statements/substatements. In the 1st survey round 102 experts and 11 relatives participated. In the 2nd survey round 68 experts and 11 relatives continued to participate. In the 3rd survey round 41 experts and 9 relatives participated. In the consensus conference 17 experts and 4 relatives of individuals with CI and in the second one-hour online conference session 14 experts and 2 relatives of individuals with CI participated.

CONCLUSION

The combination of the three assessment methods self-report, proxy-report and observation across all stages of CI is the preferred method and should be used whenever possible. As domains Physical capacity, Psychological, Level of Independence, Social Relationships, Environment and Spirituality/Relogion/Personal Beliefs should be assessed.

A Visual Analog Scale for Self-Reported Quality of Life: A Comparison of VAS and QoL-AD in Older Adults

PURPOSE

People with dementia (PWD) are one of the fastest-growing clinical populations for speech-language pathologists. Self-reported quality of life (QoL) assessments are critical patient-reported outcome measures that align with person-centered care principles. However, proxy-reporting is most often used due to assumptions that PWD cannot provide reliable self-report. Visual analog scales (VASs) have been successfully used with people with expressive and cognitive deficits to measure subjective constructs such as QoL, mood, and pain. The purpose of this project is to evaluate the feasibility and reliability of a VAS QoL assessment tool.

METHODS

Twenty older adults free of cognitive impairment were assessed using the quality of life in Alzheimer's disease (QoL-AD) and the QoL-AD in combination with a VAS (VAS QoL-AD). The construct validity, internal consistency, and test-retest reliability of the VAS QoL-AD were assessed by performing both assessments twice, 4 weeks apart.

RESULTS

Significant correlations between the overall VAS QoL-AD and the QoL-AD scale ratings, between most of the QoL-AD and VAS QoL-AD subtests, and between the first and second assessment scores were observed.

CONCLUSIONS

Results indicated strong construct validity, internal consistency, and test-retest reliability of the VAS QoL-AD in people without dementia. These results warrant further research into the development of a dementia-specific, self-reported VAS QoL scale for PWD.

Painting for a Purpose: A Visual Arts Program as a Method to Promote Engagement, Communication, Cognition, and Quality of Life for Individuals With Dementia

PURPOSE

The arts (e.g., music and painting) have received considerable theoretical and observational support as a cognitive stimulation technique for persons living with dementia (PLWD). However, particularly for visual arts, limited empirical support exists. Therefore, the purpose of this study was to pilot a free-form arts program for PLWD in the context of a cognitive stimulation paradigm and measure subsequent engagement, communication, cognitive-linguistic function, and quality of life.

METHOD

Three PLWD (one each in mild-to-moderate, moderate, and moderate-to-severe stages) were referred for study participation by a local long-term care facility. A single subject across subjects, ABA reversal design was used to assess intervention effects over a period of 8 weeks, in comparison to an active control condition (cooking activity). Cognitive-linguistic function and quality of life were assessed using standardized measures at baseline and follow-up. Engagement and communication were probed regularly across each study phase.

RESULTS

Significant changes were seen in participants' engagement and communication during painting sessions compared to the control activity. A nonsignificant positive trend was noted for self-rated quality of life from baseline to follow-up. Pre-post testing revealed nominal change in cognitive-linguistic functions.

CONCLUSIONS

An arts program led to significant increases in constructive engagement and communication and a trend toward increased self-rated quality of life for the three PLWD. The fact that these changes were not sustained outside intervention sessions (i.e., pre-post testing) is consistent with the need for a larger paradigm shift in which rehabilitation specialists-including speech-language pathologists-better integrate creative, meaningful activities into the everyday lives of PLWD to maximize ongoing engagement, communication, and quality of life.

Psychometric Properties of the ICECAP-O Quality of Life Measurement Tool When Self-reported by Community-dwelling Older People With Mild and Moderate Dementia

To evaluate interventions designed to improve the quality of life of people with dementia (PWD), there is a need for psychometrically validated instruments. We tested the psychometric properties of the ICEpop CAPability measure for Older people (ICECAP-O) as a self-report measure of quality of life with PWD. We used data from a randomized controlled trial of Tai Chi with 83 community-dwelling older people with mild and moderate dementia. The ICECAP-O was found to be valid with correlations in the expected directions for fear of falls (r=-0.36, P=0.001) and age (r=0.12, P=0.29), sensitive to change (mean difference=0.051, P=0.04, d=0.51), and have an adequate factorial structure. The ICECAP-O is a valid, generic measure of quality of life for use with PWD without a proxy.

Effects of Cognitive Rehabilitation on the Psychological Capital of the Elderly with Dementia

Background: Dementia affects mental health and psychological capital indicators, which disappear with gradual deterioration in mental and cognitive functions. Gradual loss of ability to function independently can cause negative emotional symptoms and even further reduce cognitive and functional impairment. Objectives: The current study aimed to investigate the effectiveness of cognitive rehabilitation on psychological capital in the elderly with dementia. Methods: The current quasi-experimental research was performed following a pre and -post test design with a control group. The effect of cognitive rehabilitation on psychological capital of patients aged 60 - 74 years who were admitted to the private Tehran clinics during 2020 was assessed. The convenience sampling method was used to select the participants. So that among eligible patients who had inclusion criteria, 11 were selected and then randomly divided into two groups. Lutans Psychological Capital Questionnaire was used to collect data. After the treatment, a post-test was carried out for all study groups. Data analysis was performed by analysis of covariance. Results: The results of the analysis of covariance indicated the effectiveness cognitive rehabilitation on psychological capital in the elderly with dementia (P < 0.05).

Opening Minds through Art: A preliminary study evaluating the effects of a creative-expression program on persons living with dementia and their primary care partners

For people living with dementia and their care partners, a decline in the ability to effectively communicate can cause significant distress. However, in recent decades, the arts have emerged as an effective care modality in fostering communication and expression for those with declining verbal skills and memory loss. Opening Minds through Art (OMA) is a national initiative that empowers people living with dementia by facilitating creative expression and social engagement through art-making in partnership with trained college student volunteers. Research has demonstrated that participation in the program benefits quality of life for those living with dementia and also improves student attitudes toward dementia. To date, however, no research has involved primary care partners. We implemented an OMA program at three residential care homes in State College, Pennsylvania, with residents cocreating artwork alongside primary care partners (i.e., a family member or primary medical personnel) over the course of four art-making sessions. We evaluated the effects of participation on quality of life and care partner burnout through pre-post use of "emotional thermometers" (measuring levels of distress, anxiety, depression, anger, and perceived quality of life), the National Institute of Health NIH emotional support scale, and the NIH caregiver assessment (care partner burnout). For people living with dementia, participation significantly increased perceived quality of life while decreasing distress, anxiety, depression, and anger (p < .01; n = 12) after each class; however, the intervention did not significantly impact perceived emotional support. For care partners, participation significantly lowered post-intervention measures of burnout and self-rated stress (p < .01; n = 9). This preliminary study suggests that a structured art-based activity appears to positively impact acute mood for patients and, importantly, decrease care partner burnout. Future research can bring more robust methods to bear in determining how to use OMA and other arts interventions to optimize social support for people living with dementia and their care partners.
