Informal support in Portugal by individuals aged 50

The intensity of informal caregiving and its implications for older caregivers: a national survey in Sweden

BACKGROUND

Informal caregiving is a crucial-albeit often invisible-part of the support system that enables older people with chronic diseases, disability, or age-related conditions to live in the community. However, providing informal care can affect caregivers' lives.

AIMS

To explore 1) the level of care intensity among older caregivers, 2) the relationship between the intensity of caregiving and the negative experiences reported by caregivers, and 3) the variations in unmet support needs depending on the intensity of caregiving.

METHODS

Between May and September 2023, we conducted a national representative survey to map informal caregivers in Sweden. A total of 25,776 older adults aged ⩾65 years were sampled. Marginal probabilities were calculated to obtain results adjusted for age, sex, and level of education.

RESULTS

A total of 15,129 people aged ⩾65 years responded to the survey (58.7%), of which 2157 were informal caregivers (14.3%). During a typical week, 68.6% of caregivers provided 1-10 h of informal care, 14.6% provided 11-29 h, and 16.8% provided at least 30 h of care. Women (63.1%) and caregivers aged ⩾75 years (64.1%) were overrepresented in the group providing high-intensity informal care. A higher intensity of care was related to reporting more negative experiences and worse health, as well as to experiencing more unmet support needs.

CONCLUSIONS

While most older informal caregivers reported low-intensity engagement and overall good satisfaction with their situation, a non-negligible fraction provides high-intensity help and has unmet needs that should be addressed by targeted interventions rather than one-size-fits-all policies.

Predicting informal dementia caregivers' desire to institutionalize through mining data from an eHealth platform

BACKGROUND

Dementia is a leading factor in the institutionalization of older adults. Informal caregivers' desire to institutionalize (DI) their care recipient with dementia (PwD) is a primary predictor of institutionalization. This study aims to develop a prediction model for caregivers' DI by mining data from an eHealth platform in a high-prevalence dementia country.

METHODS

Cross-sectional data were collected from caregivers registering on isupport-portugal.pt. One hundred and four caregivers completed the Desire to Institutionalize Scale (DIS) and were grouped into DI (DIS score ≥ 1) and no DI (DIS score = 0). Participants completed a comprehensive set of sociodemographic, clinical, and psychosocial measures, pertaining to the caregiver and the PwD, which were accounted as model predictors. The selected model was a classification tree, enabling the visualization of rules for predictions.

RESULTS

Caregivers, mostly female (82.5%), offspring of the PwD (70.2), employed (65.4%), and highly educated (M 15 years of schooling), provided intensive care (Mdn 24 h. week) over a median course of 2.8 years. Two-thirds (66.3%) endorsed at least one item on the DIS (DI group). The model, with caregivers' perceived stress as the root of the classification tree (split at 28.5 points on the Zarit Burden Interview) and including the ages of caregivers and PwD (split at 46 and 88 years, respectively), as well as cohabitation, employed five rules to predict DI. Caregivers scoring 28.5 and above on burden and caring for PwD under 88 are more prone to DI than those caring for older PwD (rules 1-2), suggesting the influence of expectations on caregiving duration. The model demonstrated high accuracy (0.83, 95%CI 0.75, 0.89), sensitivity (0.88, 95%CI 0.81, 0.95), and good specificity (0.71, 95%CI 0.56, 0.86).

CONCLUSIONS

This study distilled a comprehensive range of modifiable and non-modifiable variables into a simplified, interpretable, and accurate model, particularly useful at identifying caregivers with actual DI. Considering the nature of variables within the prediction rules, this model holds promise for application to other existing datasets and as a proxy for actual institutionalization. Predicting the institutional placement of PwD is crucial for intervening on modifiable factors as caregiver burden, and for care planning and financing.

Profiling early adopters of 'iSupport-Portugal': a country-specific version of a worldwide adapted digital support program for informal caregivers of people with dementia

Introduction

Informal caregivers are the backbone of dementia care. iSupport is a World Health Organization digital support program for caregivers of people with dementia (PwD) that has been culturally adapted in several countries. iSupport was previously assessed for its feasibility in Portugal, and this country-specific version is now being utilized as a remote measurement tool (RMT). It constitutes the first internationally developed iSupport platform that is technically and scientifically enhanced to collect data on sociodemographic, clinical, and psychosocial variables of dementia care dyads. This paper characterizes the early adopters of iSupport-Portugal and discusses its exploration as a RMT.

Methods

Cross-sectional data were collected between February and July 2023 from users registering on isupport-portugal.pt. To characterize caregivers and PwD, eligibility was limited to unpaid caregivers assisting community dwelling PwD (n = 173). Data were collected through self-administered instruments in users' accounts. Caregivers completed psychosocial measures on burden, anxiety, depression, quality of life, desire to institutionalize and usage of community services. Textual data on caregivers' needs underwent content analysis.

Results

Among the early adopters of iSupport-Portugal (n = 365), 52.3% were informal caregivers, while 44.7% were health/social care professionals or others. Most caregivers were female (82.7%), middle-aged (M 51.7 years), highly educated (M 15.3 years) and supporting a parent (70.5%). Caregivers cared for a median of 24 h/week and 60.8% lived with the PwD. Neuropsychiatric symptoms were reported for 94.1% of PwD, who scored as moderately dependent (Barthel Index: M 14.0). Significant burden was reported by 88.4% of caregivers (≥21 on ZBI-22). Among caregivers scoring borderline or abnormal (≥8 on HADS) for anxiety, depression, or both (75.5%), 30.8% sought mental health counseling. Caregivers supporting a PwD not using community services scored higher on anxiety (p = 0.003), and depression (p = 0.009). Text data revealed unmet practical, emotional, and informational needs.

Discussion

iSupport-Portugal has garnered fair initial interest from caregivers, particularly from those who are children, highly educated, and employed. Early adopters exhibited significant psychological distress, and both practical and emotional needs, which contrast with limited use of support services for themselves and the PwD. iSupport-Portugal shows promise for descriptive research on care dyads, particularly among newer generations of caregivers.

The Longitudinal Association between Co-Residential Care Provision and Healthcare Use among the Portuguese Population Aged 50 and Over: A SHARE Study

Co-residential care is associated with poor caregiver health and a high burden. Although Portugal relies heavily on co-residential care by individuals aged 50 and over, studies on the impact of co-residential care provision on Portuguese caregivers' healthcare use are lacking. This study aims to analyze the impact of co-residential care (spousal and non-spousal care) on healthcare use of the Portuguese population aged 50 plus. Data from waves 4 (n = 1697) and 6 (n = 1460) of the Survey of Health, Ageing and Retirement in Europe (SHARE) were used. Negative Binomial Generalized Linear Mixed Models with random (individual level) and fixed (covariates) effects were performed. The results show that the number of visits to the doctor decrease significantly over time for the co-residential spousal caregivers as compared to the non-co-residential caregivers. This result highlights the fact that the Portuguese co-residential spousal caregiver group is at a higher risk of not using healthcare, thus jeopardizing their own health and continuity of care. Promoting more accessible healthcare services and implementing public policies adjusted to the needs of informal caregivers are important to improve the health and healthcare use of Portuguese spousal co-residential caregivers.

Use of dementia and caregiving-related internet resources by informal caregivers: A cross-sectional study

Informal dementia caregivers are at greater risk of experiencing physical and mental health issues as compared to the general population. Internet-based resources may provide accessible opportunities to backing informal dementia caregivers by addressing their information and support needs. This cross-sectional study aims to characterize the use of dementia and caregiving-related internet resources by caregivers and identify variables associated with such use. Primary data were collected through a web-based survey (N = 158). Linear regression models were used to assess the associations of predisposing, enabling, and need variables with the frequency of using the internet for caregiving-related purposes. Most caregivers (93%) have ever used the internet to gather general information about dementia. The frequency of using internet resources was, however, moderate. The multivariable linear regression model suggests that being younger (β = −0.110, p = 0.009), not having a source of support to provide care (β = −2.554, p = 0.012), having used a face-to-face psychosocial intervention at some point (β = 2.731, p = 0.003), being employed (β = 2.558, p = 0.013), and appraising one's own physical health negatively (vs. appraising it as similar; β = 3.591, p < 0.001), are associated with a higher frequency of using caregiving-related internet resources. Our findings confirmed the association of age and perceived health status with caregiving-related internet use reported in other studies. The role of enabling variables as lifetime access to psychosocial interventions and having a usual source of support to provide care was a new addition. This study informs the design and deployment of information and support to dementia caregivers.

Ageing and Long-Term Informal Care: The Reality of Two Countries in Europe: Denmark and Portugal

The knowledge of long-term informal care is particularly interesting for social and health measures related to ageing. This study aims to analyze how Portugal differs from Denmark regarding long-term informal care, specifically referring to personal care received by older people. A cross-sectional study was developed in Portugal and Denmark through the Survey of Health, Ageing and Retirement in Europe (SHARE) in 2015, with a total of 2891 participants. Descriptive statistics and logistic regressions were performed. The findings suggest a significant association for older people from Portugal who receive long-term informal care from non-household caregivers and household caregivers. Moreover, as they age and are from Portugal, their availability to receive long-term informal care from non-household caregivers increases. Furthermore, older people in Portugal are more likely to receive long-term informal care from a household caregiver. It is important to take a closer look at long-term informal care in both countries and think about healthy ageing policies in the current context of the ageing population. This study provides knowledge about disaggregated health data on ageing in the European region, helping to fill research gaps related to older people.

Feasibility of an online training and support program for dementia carers: results from a mixed-methods pilot randomized controlled trial

Background

iSupport is an online program developed by the World Health Organization to provide education, skills training, and social support to informal carers of persons with dementia. This pilot study examines the feasibility of the protocol for a main effectiveness trial of iSupport-Portugal and explores how the intervention and control arms compare over time on well-being outcomes.

Methods

A mixed-methods experimental parallel between-group design with two arms is followed. Participants were recruited nationwide, by referral or advertising, through the National Alzheimer’s Association. Inclusion criteria are being Portuguese adults, providing e-consent, providing unpaid care to someone with dementia for at least 6 months, experiencing relevant scores on burden (≥ 21 on ZBI) or depression or anxiety (≥ 8 on HADS), and using webpages autonomously. Participants were consecutively randomized to receive iSupport-Portugal or an education-only e-book and were not blinded to group assignment. Data were collected online with self-administered instruments, at baseline, 3 and 6 months after. Outcomes comprise caregiver burden, depression, anxiety, QoL, positive aspects of caregiving, and self-efficacy. Generalized estimating equations were used to estimate group, time, and group-by-time effects. Intervention engagement data were extracted from iSupport’s platform. Semi-structured interviews were conducted.

Results

Forty-two participants were allocated to the intervention (N = 21) and control (N = 21) arms. Participation (78.1%) and retention rates (73.8%) were fair. More carers in the control arm completed the study (N = 20, 95.2%) than in the intervention arm (N = 11; 52.4%) (χ² = 9.98, p = .002). Non-completers were younger, spent less time caring, and scored higher on anxiety. Among carers in the intervention arm, the average attendance rate was of 53.7%. At post-test 38.9% of participants still used iSupport; the remainder participants interrupted use within 2 weeks (Mdn). For per-protocol analyses, significant group-by-time interaction effects favouring the intervention were found for anxiety (Wald χ2 = 6.17, p = .046) and for environmental QoL (Wald χ² = 7.06, p = .029). Those effects were not observed in intention-to-treat analyses adjusted for age. Interviewees from the intervention arm (N = 12) reported positive results of iSupport on knowledge and on experiencing positive feelings. No adverse effects were reported.

Conclusions

This study provides information for a forthcoming full-scale effectiveness trial, as on the acceptability and potential results of iSupport-Portugal. iSupport is suggested as a relevant resource for Portuguese carers.

Assessing attitudes towards online psychoeducational interventions: Psychometric properties of a Brief Attitudes Scale

Participant attitudes are an explanatory factor for attrition in online health-related interventions. However, its assessment prior to interventions start is uncommon, partly because proper measures are missing. This study presents the psychometric properties of a new scale measuring attitudes towards online psychoeducational interventions (OPIs). Structural validity, reliability and screening performance of the Online Psychoeducational Intervention - Brief Attitudes Scale (OPI-BAS) were studied in a sample of 157 dementia caregivers. Scale cut-off scores were derived to categorise the participants into 'OPIs sympathisers' or 'non-sympathisers'. Groups were compared across sociodemographic and internet use variables. A parsimonious five-item version of OPI-BAS demonstrated good structural validity, with one factor explaining 63.3% of variance. Internal consistency of the scale was high (α = 0.85). OPI-BAS showed good screening performance in identifying individuals with either a preference to use conventional face-to-face or online psychoeducational interventions (area under the curve = 0.84). An optimal cut-off score of 20 was suggested by the receiver operating characteristic graph, providing good sensitivity (74%) and specificity (84%). No significant differences were found between groups on sociodemographic and internet use variables. Attitudes towards OPIs were overall positive, but face-to-face interventions were preferred. This study offers preliminary support to the psychometric quality of OPI-BAS. This short scale has practical applications for research and intervention.

User feedback and usability testing of an online training and support program for dementia carers

BACKGROUND

eHealth interventions have been explored to provide convenient support and training to informal dementia carers. Design and usability issues may however hinder user acceptance of Web-based interventions. iSupport is an online program developed by World Health Organization (WHO) to support informal dementia carers.

PURPOSE

This study gathers user-feedback and evaluates the usability of the European-Portuguese version of iSupport.

METHODS

A mixed-methods study was conducted. Two focus groups discussions (n = 15) and 15 usability test sessions were conducted with carers and health/social support professionals to collect data on user satisfaction and requirements on the program's contents and Web interface. The usability testing protocol comprised pre/post-test surveys, a structured interview and observation of task performance in the Web platform. Content analysis of text data was performed by two independent coders.

RESULTS

Success rates were superior to 80% for most tasks. An average score of 89.5 on the System Usability Scale demonstrated an excellent perception of the program's usability. The program was perceived as trustworthy, and participants were globally satisfied with its aesthetics and easiness of use. Feedback and personalization were valued functional requirements, while no consensus was found for mood self-assessment or professional/peer interaction features. Lessons were considered culturally fit, thematically pertinent, and comprehensive. Suggestions for improvement were wide-ranging from program's layout to accessibility, usability, functional requirements, content format and lessons' themes.

CONCLUSIONS

This study derives user requirements for an evidence-based program for dementia carers. Both the study findings and usability assessment methodology can be imported to the development of similar programs worldwide.

A Multipurpose Platform for Ambient Assisted Living (ActiveAdvice): Usability Study

BACKGROUND

Aging of the global population is slowly paving the way for new markets for care products and services. The desire of older people to maintain their independence while remaining at home is boosting the development of ambient assisted living (AAL) solutions. Lack of user awareness of AAL solutions paired with an insufficient use of user-centered and participatory design approaches in the development of these products has hindered the uptake of these solutions by end users.

OBJECTIVE

This study aims to describe the usability and users' experiences within a novel platform, ActiveAdvice, aimed at offering advice and a holistic market overview of AAL products and services.

METHODS

Usability tests were performed on the developed platform among identified prospective end users, with 32 older adults and informal carers from 4 European countries being part of the user tests. The usability and appeal of the web interface design, information flow, and information architecture were analyzed by collecting both objective and subjective measures. These would include pretest and posttest surveys, along with a series of think-aloud tasks to be performed within the platform.

RESULTS

The outcomes suggest that the ActiveAdvice platform's objectives and functionalities are mostly aligned with the needs and expectations of end users, who demonstrated interest in using it, stressing its purpose along with its simple and intuitive interaction. Task completion rates were high, and participants had good satisfaction rates when navigating the platform. However, the tests still advocate for an improved design at some points and better disclosure of information.

CONCLUSIONS

Our findings shed light on a few peculiarities of interface design, information architecture, user needs, and preferred functionalities, which should be applied to future developments of similar platforms with related services. The AAL field could benefit from tools supporting the dissemination of available AAL solutions and how they can improve one's quality of life. These tools may benefit not only older adults but also caregivers, business owners, and governmental employees.

Do European co-residential caregivers aged 50+ have an increased risk of frailty?

One important health challenge associated with ageing is frailty, which has been acknowledged as a new public health priority. However, only a few studies have explored the relationship between providing care at older ages and frailty. The main objective of this study is to assess whether there is an association between providing co-residential care and frailty, according to gender and from a European cross-sectional perspective, among the population aged 50+. Data from 17 European countries that participated in wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE) is used (N = 52,073). Multinomial logistic regressions were used to estimate caregivers' chances of frailty. The results show that the prevalence of pre-frailty and frailty differs according to the caregiver's status, gender and the European region. The highest prevalence of pre-frailty was found in the group of female caregivers from Northern countries (57.3%), and the highest prevalence of frailty was found in the group of female caregivers from Southern countries (29.3%). Providing co-residential care is positively associated with the risk of being pre-frail in women, in all European regions (Northern: OR 1.724, 95% CI 1.190-2.496; Central: OR 1.213, 95% CI 1.010-1.456; Eastern: OR 1.227, 95% CI 1.031-1.460; Southern: OR 1.343, 95% CI 1.103-1.634), and with being frail for both genders in the Southern region (female: OR 1.527, 95% CI 1.060-2.200; male: OR 1.644, 95% CI 1.250-2.164). The results of this study suggest that female co-residential caregivers are a greater risk of being pre-frail in all European regions except Southern Europe, where male and female co-residential caregivers are a greater risk of being frail, compared with non-caregivers. European policy makers should create political measures to prevent and reverse frailty among European co-residential caregivers.

Health impact of providing informal care in Portugal

BACKGROUND

Middle-aged and older adults play an important role in the provision of informal support, however, the impact on the health of those individuals who provide informal care is unclear. The main objectives of this study are: (1) to assess the prevalence of co-residential caregiving provided by individuals aged 50+; (2) to analyze differences between the group of Portuguese co-residential caregivers and the group of Portuguese non-caregivers; (3) to examine the longitudinal effect of providing informal care on the health of co-residential informal caregivers in Portugal.

METHODS

Data from wave 4 and wave 6 of the Survey of Health Ageing and Retirement in Europe (SHARE) were used. A linear mixed model and a generalized mixed model were used to analyze the longitudinal effect of providing informal care on the health (physical health and depressive symptoms) of Portuguese individuals aged 50 + .

RESULTS

In both SHARE waves analyzed, Portugal had the highest percentage of co-residential caregivers aged 50+. At baseline, the Portuguese co-residential caregiver population, compared to non-caregivers, has a lower percentage of employed individuals (14.9% compared to 25.7%) and a higher percentage of individuals with four or more depressive symptoms (56.4% compared to 35.5%). The caregivers also have a lower quality of life (CASP-12) (30.93 compared to 32.59). Marginal differences in educational levels between the caregiver and non-caregiver groups were also found, with co-residential caregivers having lower levels of education (72.3% have ISCED 0-2 compared to 64.7%), lower levels of cognitive function (- 2.321 compared to - 1.784), lower levels of physical health (- 0.180 compared to - 0.076) and lower engagement in moderate or vigorous physical activity (14.9% compared to 21.5%). Longitudinal models reveal that providing care within the household is not associated with physical health (b = 0.048; se = 0.035; p = 0.167), but is associated with depressive symptoms (OR = 1.609; 95% CI = 1.141-2.271; p = < 0.010).

CONCLUSIONS

Portugal has the highest percentage of co-residential caregivers aged 50+. In that country, providing informal care to a household member is associated with depressive symptoms. Portuguese policymakers should therefore promote programs to prevent and alleviate the depressive symptoms experienced by individuals aged 50+, who provide co-residential care.

Access and Retention of Informal Dementia Caregivers in Psychosocial Interventions: A Cross-Sectional Study

Underutilization of community care services has been described for informal dementia caregivers. Most research has however examined caregivers' access to home or respite care rather than to services for themselves. The aims of this study are: to describe access and retention of informal dementia caregivers in psychosocial interventions; examine the perceived effects of interventions among users and motives for non-use among non-users; and compare caregivers with and without lifetime access and retention in psychosocial interventions across predisposing, enabling and need variables. A cross-sectional study was conducted with 179 Portuguese caregivers, who replied to a web-based survey. Participants were fairly distributed among those who have never (49.7%) and those who have ever accessed (50.3%) psychosocial interventions. Individual psychological support was the most used intervention (32.2%). Caregivers' age, time elapsed since diagnosis and the relationship with the care receiver were associated with lifetime access to various intervention types. Dropout was above 50% for most intervention types, except for psychoeducation (31.8%). Associations were found between a history of dropout/retention and caregivers' education, perceived mental health, and the number of hours spent caring. Most users of psychoeducational interventions (>80%) appraised it as beneficial to learn about the disease, provide quality care and cope with caregiving. Informational barriers were the most reported by non-users of psychoeducational interventions (45.1%). The findings show that dementia caregivers continue facing barriers to use and keep using community services for themselves. The influence of particular predisposing and need variables on access to psychosocial interventions can vary according to intervention types.

Dementia caregivers training needs and preferences for online interventions: A mixed-methods study

AIM

To explore how informal caregivers of persons with dementia perceive training needs and preferences in the context of online training and support interventions.

BACKGROUND

Informal dementia caregivers commonly present high needs across several domains. Paradoxically, they are more likely to have unmet needs and lower levels of service usage when compared to other caregivers. Most studies on unmet needs of dementia caregivers have been quantitative and resorted to assessment checklists, with a minority focusing on subjective needs.

DESIGN

Mixed-methods.

METHODS

Eighty-eight Portuguese digitally literate caregivers filled a web-based questionnaire collecting written statements on training needs and importance ratings on design preferences. Content analysis of text data was carried out by two independent researchers to check the reliability of the analytic process. Descriptive statistics were produced for ratings on design preferences, and associations with caregivers' sociodemographic and care-related variables were inspected. Reporting followed the criteria for reporting qualitative research checklist.

RESULTS

Five main categories of training needs have emerged: knowledge of dementia; care interactions; caregiver self-care; community resources; and laws or regulations affecting the caregiver and the care recipient. The most reported need was on care interactions, on the subcategory of providing good quality care. Thematic prominence was analysed according to the caregiver, caregiving and health perception characteristics, with trends found on formal education, relationship with the care recipient, number of hours caring per week, perceived level of dependence of the care recipient and perceived physical and psychological health status of the caregiver. Most valued design features included the use of plain language, easy to interact interface and communication with a professional.

CONCLUSIONS

Findings from this study further support the delivery of comprehensive interventions addressing the multiple needs of caregivers.

RELEVANCE TO CLINICAL PRACTICE

Clues are provided for the delivery of online interventions, and conclusions are useful to health professionals working with dementia caregivers.

Training and support for caregivers of people with dementia: The process of culturally adapting the World Health Organization iSupport programme to Portugal

BACKGROUND

Informal caregivers of people with dementia often struggle with several stressors, and their mental and physical health can be negatively affected by providing care. iSupport is an online self-help programme designed by the World Health Organization to provide education, skills training, and support to those caregivers.

PURPOSE

This paper describes the development of an adapted version of iSupport to the Portuguese culture. We present the adaptation process, methods used and results for the country-specific version.

METHODS

The adaptation of iSupport was operationalised in five steps: needs assessment; content translation by an authorised translator and technical accuracy check by health professionals; cultural adaptation; independent appraisal of contents by an expert panel; and fidelity check by programme authors.

RESULTS

Findings indicated the adjustments needed in the original iSupport contents. Overall, 323 text excerpts were proposed to adaptation, comprising semantic and conceptual equivalence of expressions, and adjustments to cultural habits, customs, traditions, local resources, and practices. The expert panel identified the need to reformulate definitions, designations, recommendations, and case studies to fine-tune the original contents to local knowledge and practices. Most adaptations were considered to be in line with the core concepts of the original programme.

CONCLUSIONS

iSupport is an innovative tool capturing the attention of several organisations around the world interested in translating, adapting, and using the programme. This paper is the first describing the methodological approach for culturally adapting iSupport, constituting an essential resource for those aiming to replicate the process or culturally adapting evidence-based interventions. Tailoring iSupport to the Portuguese context was critical to accommodate the cultural experiences of the target group as well as the knowledge, theoretical approaches, and practices of local professionals. The European-Portuguese version of iSupport introduces the adjustments needed to implement a useful new intervention programme aimed at minimising the psychological distress of Portuguese caregivers.

Online training and support program (iSupport) for informal dementia caregivers: protocol for an intervention study in Portugal

BACKGROUND

Informal caregivers (IC) of people with dementia (PwD) are at greater risk of developing physical and mental health problems when compared to the general population and to IC of people with other chronic diseases. Internet-based interventions have been explored for their potential to minimize the negative effects of caring, accounting for their ubiquitous nature, convenient delivery, potential scalability and presumed (cost) effectiveness. iSupport is a self-help online program developed by the World Health Organization (WHO) to provide education, skills training and support to IC of PwD. This paper describes the design of an intervention study aimed at determining the effectiveness of a Portuguese culturally adapted version of iSupport on mental health and other well-being outcomes.

METHODS

The study follows an experimental parallel between-group design with two arms: access to the five modules and twenty-three lessons of "iSupport" for three months (intervention group); or access to an education-only e-book (comparison group). One hundred and eighty four participants will be recruited by referral from national associations. Inclusion criteria are: being 18 years or older and provide e-consent; being a self-reported non-paid caregiver for at least six months; of a person with a formal diagnosis of dementia; being skilled to use internet; and experience a clinically relevant level of burden (≥ 21 on Zarit Burden Interview) or depression or anxiety symptoms (≥ 8 on Hospital Anxiety and Depression Scale). Data is collected online, resorting to self-administered instruments, at baseline, 3 and 6 months after baseline. The primary outcome is caregiver burden, measured by the Zarit Burden Interview. Symptoms of depression and anxiety, quality of life, positive aspects of caregiving and general self-efficacy are secondary study outcomes. The data analysis will follow an Intention-to-treat (ITT) protocol.

DISCUSSION

This protocol is an important resource for the many organizations in several countries aiming to replicate iSupport. Findings from this intervention study will offer evidence to bolster an informed decision making on scaling up iSupport as a new intervention program with minimal costs aimed at minimizing the psychological distress of IC of PwD in Portugal and elsewhere.

Effects of a community intervention program for dementia on mental health: the importance of secondary caregivers in promoting positive aspects and reducing strain

The study presents a community intervention program targeted at caregivers of individuals with dementia, and assesses its main outcomes in terms of caregiver strain, positive aspects of care, and physical and mental health. A total of 187 caregivers completed a 10-week psychoeducational program and were assessed at baseline, post intervention and at 6-month follow-up. The evaluation of the program was performed using multivariable linear mixed effect models. Results showed an improvement in mental health, an increasing of satisfaction with care, and a lessening of caregiving strain. Nevertheless, such effects were distinctively associated with important objective circumstances of care, namely the existence of a secondary caregiver, the number of hours of care, the dependency level of the care-recipient, and the age of the caregiver. To foster wellbeing of the caregivers, intervention should particularly focus on the share of caregiving with others, and on uncovering positive aspects of care.
