Brief Summary

Dementia has a major impact on people with dementia and their family. Informal caregivers of people with dementia are at higher risk of developing depressive symptoms compared to informal caregivers of people with other chronic diseases. Therefore, supporting this group of informal caregivers is particularly important. With an online program based on Acceptance and Commitment Therapy (ACT), this study supports caregivers of people with dementia to lead a more meaningful and less stressful life. In addition to following the online program, caregivers are supported weekly by a coach, who helps to set goals, map important values in life, and take actions in relevant areas. The current study aims to examine the (1) feasibility and acceptability of the intervention and its procedure and; (2) preliminary effectiveness of the intervention on clinical outcomes (e.g. psychological flexibility and self-competence); and (3) maintenance of change after the intervention in short-and long-term follow-ups. This study includes a single-arm, non-randomized trial with a baseline assessment, a 9-week internet-based intervention period, a post-intervention assessment, and two follow-ups at 3 and 6 months. ACT is a promising form of therapy that has previously been shown to be effective in increasing the mental well-being of caregivers. However, this is the first study to combine online ACT modules, goal-setting, and weekly coaching for informal caregivers of people with dementia.

Arm && Interventions

Group	Intervention	Description
Single-arm non-randomised	Blended intervention based in acceptance and commitment therapy	This study includes a baseline assessment, a 9-week (with the possibility of extension to 12 weeks) blended intervention period, a post-intervention assessment, and two follow-ups at 3 and 6 months. Informal caregivers of people with dementia (with at least 18-year-old) with no restriction in terms of sex, educational level, or ethnic background will be included.

Primary Outcome Measures

Name	Time	Method
Perceived feasibility	Will be assessed after completing each module (during the intervention). 9 time for 9 modules.	Brief self-report feasibility questionnaire
Assessing change in depression, anxiety, and stress	Will be assessed at baseline, after completing the intervention (9 to 12 weeks), 3month after intervention, and 6 month after intervention..	Measure the emotional states of depression, anxiety and stress will be assessed by DASS-21 self-report questionnaire. DASS-21 has three sections (7-items per section) that measure depression, anxiety, and stress on a 4-point Likert scale (0= the statement did not apply to me at all, 4= the statement applied to me very much or most of the time. DASS-21 is a validated scale that has been used in previous studies and has been recommended for measuring the dimensions of depression, anxiety, and stress.
Assessing change in self efficacy	Will be assessed at baseline, after completing the intervention (9 to 12 weeks), 3month after intervention, and 6 month after intervention..	The Caregiver Self-Efficacy Scale (CSES) is based on a Dutch adaptation of the Lorig et al. CSES evaluates caregiver self-efficacy (four item) and service-use self-efficacy (five items) and item scores range from 1 (uncertain) to 10 (very certain). Previous research has shown that CSES is valid and reliable
Assessing change in sense of competence	Will be assessed at baseline, after completing the intervention (9 to 12 weeks), 3month after intervention, and 6 month after intervention..	Informal caregivers' sense of competence indicates the feelings of being capable of caring for a person with dementia. Short Sense of Competence Questionnaire (SSCQ) is a valid and reliable scale which has been used in previous studies with a similar target population and consists of seven items rated on a 5-point scale from 1 ("agree very strongly") to 5 ("disagree very strongly")
Perceived feasibility and acceptability	9 (to 12) times. One telephone call per week over 9 (to 12) weeks of intervention.	Will be assessed qualitatively during coaching sessions
Assessing change in perceived burden	Will be assessed at baseline, after completing the intervention (9 to 12 weeks), 3month after intervention, and 6 month after intervention..	Caregiver burden will be measured by a one-item questionnaire. The perseverance-time question will ask: if the informal caregiver's current situation persists, for how long (in month) the informal caregiver thinks they are able to maintain caregiving. This questionnaire is a good predictor for institutionalisation.
Acceptability	Will be assessed after completing the 9-week intervention	Will be assessed qualitatively during a semi-structured interview based on Program Participation Questionnaire (PPQ)
Attrition	During the study (duration of study is expected to be 1.5 year)	Number of drop outs of study after collecting informed consent
