Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The online program for carers of people with dementia is comprised of an educational fact sheet explaining (i) dementia, (ii) behaviour changes in people with dementia, and (iii) how to plan activities for people with dementia. It also includes 20 animations exploring behaviours common in dementia and 20 associated problem-solving worksheets that allow the participant to apply the videos to their own situation. Carers can access the program as many times as they would like by logging in online over 8 weeks. Adherence is monitored by collecting self-report and user-access data.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants apply online, complete eligibility questionnaires, and if eligible are randomised. Allocation is completed by computer software using randomisation table and therefore concealed from researchers.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e., computerised sequence generation)
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Efficacy
Statistical methods / analysis
A meta-analysis of 23 carer programs for managing symptoms of dementia yielded an effect size of 0.34 (Brodaty & Arasaratnam, 2012). A power analysis was conducted to inform the sample size using a conservative expected effect size difference between the groups of 0.2. It is estimated that we would require 200 participants to reach a significance level of p=0.05, at 80% power (Cohen, 1988).

Analyses will be carried out using SPSS. Descriptive statistics will be computed for demographic questions and the online questionnaires (including internal consistency). Relationships across measures (e.g., bivariate correlations and regression analyses) will be examined. Group by time interactions will be examined using linear mixed models to determine whether the program reduced carer distress and burden, in comparison to the educational website. Content analysis will be undertaken to determine qualitatively how acceptable and useful carers perceived the program to be.
