Recovery from burden: informal caregiver profiles that predict treatment success

Longitudinal effect of dementia carers' sense of coherence on burden

BACKGROUND

A sense of coherence (SOC) could help us better understand why there are individuals who cope better than others in similar situations. The study aimed to assess the effect of SOC on the course of burden reports in relatives of persons with dementia.

METHODS

This was a prospective cohort study of 156 dementia carers. The SOC was assessed by the Orientation to Life Questionnaire (OLQ-13), burden by Burden Interview, and personal and contextual characteristics were collected via ad hoc questions. The main dementia symptoms, including functional difficulties (Disability Assessment for Dementia), neuropsychiatric symptoms (Neuropsychiatric Inventory), and cognitive impairment (Mini-Mental State Examination), were also assessed. A general linear model was adjusted to determine the effect of SOC and other covariates on burden throughout the follow-up. Burden differences between baseline and 12 and 24 months were analysed, and the baseline OLQ-13 score was grouped by quartiles.

RESULTS

The global burden reported increased after 24 months (F = 9.98; df = 2; p < 0.001), but not equally for all carers; daughters reported the greatest increase. SOC, functional disability, and neuropsychiatric disorders showed a significant effect on burden, but time did not. Carers with higher SOC at baseline tend to remain with lower burden levels, whereas carers with low SOC reported higher burden at each visit.

CONCLUSIONS

This study reports evidence of the effect of SOC on burden at baseline, 12 and 24 months of follow-up. Burden scores differ by carers' SOC; those with higher SOC showed lower burden levels, whereas the low-SOC group reported a greater burden at each visit.

Psychogeriatric Inventory of Disconcerting Symptoms and Syndromes (PGI-DSS): validity and reliability of a new brief scale compared to the Neuropsychiatric Inventory for Nursing Homes (NPI-NH)

OBJECTIVES

To validate the Psychogeriatric Inventory of Disconcerting Symptoms and Syndromes (PGI-DSS), a single scale in A4 format comprising four disconcerting syndromes (violence, refusal, words, and acts). The scale enables an immediate conversion of a qualitative assessment to a quantitative assessment. The PGI-DSS was compared with the Neuro Psychiatric Inventory for Nursing Homes (NPI-NH).

DESIGN

Cross-sectional descriptive and correlational studies.

SETTING

Thirty geriatric care units and nursing homes.

PARTICIPANTS

Raters interviewed nurses and nursing assistants in charge of older adults hospitalized in geriatric care units or living in nursing homes (N = 226).

MEASUREMENTS

The French version of the PGI-DSS and the French version of the NPI-NH.

RESULTS

The correlation coefficient between the PGI-DSS and the NPI-NH was 0.70 (p < 0.0001). The PGI-DSS threshold score corresponding to the NPI threshold score was 17 (specificity: 87%, sensitivity: 63%). Four statistical factors, corresponding to the four clinical syndromes, explained 53.4% of the total variance. The internal consistency of the PGI-DSS (Cronbach's alpha = 0.695) was higher than that of the NPI-NH (Cronbach's alpha = 0.474). Test-retest reliability was better for the PGI-DSS than for the NPI-NH. The intraclass correlations were 0.80 [0.73; 0.86] and 0.75 [0.67; 0.83], respectively. Interrater reliability was better for the PGI-DSS than for the NPI-NH. The intraclass correlations were 0.65 [0.55-0.76] and 0.55 [0.43-0.68], respectively.

CONCLUSION

The PGI-DSS was developed to overcome the limitations of the NPI-NH. New, brief, easy to administer in less than 4 minutes, foldable in four parts, pocket-sized, easy-to-read in the palm of the hand, PGI-DSS could have similar or better statistical properties than the NPI-NH. Whereas the 10 domains in the NPI-NH have clinical utility for clinicians, the four easily understandable syndromes in the PGI-DSS can help avoid inappropriate attitudes and can guide psychosocial interventions. It could likewise improve dialogue between caregivers and clinicians.

Reflections on quality of care for persons with dementia: moving toward an integrated, comprehensive approach

With current projections indicating that the number of persons with dementia will continue to rise in the near future (Alzheimer Disease International, 2018), dementia is now recognized as a public health priority worldwide. Despite the great efforts and budgets invested; as of yet, no cure or highly effective treatments for dementia are available. Thus, the development of care practices to improve the wellbeing and quality of life of persons with dementia and their caregivers have become primary aims in the management of the condition (Ortega et al., 2018).
