Adaptation of a psycho-educational group programme to improve coping in dementia caregiving: a feasibility study with mixed-methods.

BACKGROUND: As the number of people living with dementia rapidly increases worldwide, the support provided by their informal caregivers remains key to the sustainability of most healthcare systems, this voluntary contribution representing 40% of the costs of dementia worldwide. Informal caregiving in dementia, however, is linked to long periods of chronic stress with frequent and serious negative consequences on the health and quality of life of the caregiver. A psycho-educational group intervention focusing on coping with the daily stress of dementia caregiving ("Learning to feel better… to help better"), developed in French-speaking Canada and showing broad effects on quality of life, was selected with the aim of 1) adapting it to a new cultural context (French-speaking Switzerland) based on identified facilitators and barriers, using a participative approach; and 2) conducting a feasibility study to evaluate whether the adapted programme showed similar or improved feasibility and effects compared to the original Canadian programme. METHODS: A mixed-methods concurrent nested design was used to evaluate the feasibility and the effects on five quantitative core outcomes. Additional qualitative data helped document in depth the acceptability and impact of the intervention. RESULTS: We shortened the programme from 30 to 21 h in total, which resulted in increased accessibility, in terms of facilitated recruitment of participants and inclusion of a broader range of informal caregivers. There were significant reductions in subjective burden (effect size: d = -0.32) and psychological distress (d = -0.48), as well as decreases in the stress reactions of informal caregivers related to the behaviour problems of the persons with dementia (d = -0.57). The qualitative results emphasized the usefulness of providing informal caregivers with structured procedures for efficiently tackling everyday challenges, and of enabling learning through a variety of channels and activities. CONCLUSIONS: Substantial improvements are associated with this 21-h group intervention, organised in 7 sessions of 3 h each, focused on learning more efficient strategies to cope with the daily stress of dementia caregiving. This intervention empowered informal caregivers to master their daily challenges with more confidence, satisfaction and calm.

Coping with dementia caregiving: a mixed-methods study on feasibility and benefits of a psycho-educative group program.

BACKGROUND: Persons with dementia experience a progressive decline associated with an increasing dependency. Most of the support they require to stay at home comes from their informal caregivers (IC). Dementia informal caregiving imposes high costs on IC's health and quality of life, related to long periods of chronic stress. Based on evidence that more adequate coping strategies can reduce chronic stress and its negative consequences, and that psycho-educative interventions have the broadest effects on IC quality of life, the program "Learning to feel better… and help better" was developed in French-speaking Canada. This group intervention focusing on coping with the daily stress of dementia caregiving showed efficacy in decreasing the behavior problems of the person with dementia and the associated stress reactions in their IC. The objectives of our study were to examine within a one group pre- and post-test design 1) the feasibility of implementing the program in two regions of French-speaking Switzerland, 2) the effects of the program, and 3) the participants' use of the trained strategies in daily life. METHOD: A mixed-methods concurrent nested design was used to quantitatively evaluate the feasibility, the effects on five core outcomes, and strategy use in daily life. Additional qualitative data documented in depth the acceptability and impact of the intervention. RESULTS: We analyzed 18 complete data sets. Regarding feasibility, qualitative and quantitative results converged towards a very good acceptance of the program and a strong implication of the participants. Regarding effects, the program resulted in substantial and significant improvements in burden (d = 0.41, p < .05), psychological distress (d = 0.54, p < .05) and self-efficacy (d = 0.43, p < .05). The qualitative results emphasized the benefits of a group format: Participants felt understood by peers, could build new social bonds and experienced reduced social isolation. Data regularly collected in daily life showed that participants were using more and more over time the strategies they learned (ß01 = 0.55, p < .001), particularly reframing. CONCLUSION: This study expands on the original one conducted by the developers of the program in French-speaking Canada, by showing the feasibility and the very promising effects of this intervention in two regions of French-speaking Switzerland.

Long-term estrogen exposure of whitefish Coregonus lavaretus induces intersex but not Lake Thun-typical gonad malformations.

A high prevalence of gonad morphological variations has been observed in whitefish Coregonus lavaretus from Lake Thun (Switzerland). To clarify the role of endocrine disruption as a possible cause of the gonad alterations, whitefish were reared in a long-term laboratory experiment under exposure to 17 beta-estradiol (E2). Fish were fed from first-feeding until 3 yr of age at a daily rate of 0 (control), 0.5 or 50 microg E2 kg(-1) fish. E2 exposure resulted in a time- and concentration-dependent increase of prevalence and intensity of intersex gonads, i.e. gonads that macroscopically appeared as either testis or ovary but microscopically contained both male and female germ cells. Four types of intersex could be distinguished: Types 1 and 2 were composed of mainly male tissue, with Type 1 containing single oocytes and Type 2 displaying an ovary-like lamellar structure of the tissue. In Type 3, an increased percentage of the tissue was occupied by female germ cells, while in Type 4, the majority of the gonad tissue consisted of female germ cells. Chronic E2 exposure additionally resulted in a concentration-dependent shift of the sex ratio towards females, a reduced condition factor, retarded gonad growth together with delayed maturation of germ cells, and elevated levels of hepatic vitellogenin mRNA. However, Lake Thun-typical alterations of gonad morphology were not induced by chronic E2 exposure. The results provide evidence that estrogen-active compounds unlikely play a role in the etiology of gonad malformations in Lake Thun whitefish.
