Abstract
The aim of the study is to examine whether providing targeted, timely and behaviourally informed prompts, via SMS, will improve the number of recipients who take a desired action in a timely manner.

During the discovery phase (scoping for the project) it was agreed that Job Seeker (Newstart and Youth Allowance) recipients in receipt of income support payments, administered by the Australian Department of Human Services, were a population of interest. These recipients are required to report each fortnight, and include any income they receive from employment.

Late reporters may have their payments terminated, which can be problematic for the client and increase departmental work in the form of increased contacts and reinstating customers back onto payments.
This trial will have seven arms and will scientifically test behaviour against some key behavioural concepts such as personalisation and loss and gain framed messages.

It is anticipated findings from this research will inform service delivery both within the lead department and across the Australian Public Service.

Experimental Design

Experimental Design
7-arm Randomised Controlled Trial.
This trial will test differently framed text messages, over several days of one week, to assess whether this communication improves on-time reporting by recipients who have reported late in the fortnight before trial commencement.
1. Customer correspondence standard (loss framed message) with a consequence for late reporting
2. Personalised customer correspondence standard (loss framed message) with a consequence for late reporting
3. Short simple message without a consequence
4. Personalised short simple message without a consequence.
5. Gain framed message (details positive consequence of on-time reporting)
6. Personalised gain framed message (details positive consequence of on-time reporting)
7. No-treatment control group

Experiment Characteristics

Sample size: planned number of clusters
N/A
Sample size: planned number of observations
12,300
Sample size (or number of clusters) by treatment arms
1,550 per treatment arm
Approximately 3,000 in control group
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Of the 80,382 individuals who were late reporting in the fortnight ending 17 Feb 2017, 35,329 (43%) were late reporting again over the next month. A sample size of 1550 per group, will provide 80% power at a 5% significance level to detect a 5 percentage point decrease in the late reporting rate (from 43% to 38%). With a larger control group (no SMS) and six treatment groups a total sample of 12,300 will be required.
