Prior work
This trial does not extend or rely on any prior RCTs.
Young people use technology to communicate, test out and develop their identities, create and join spaces to reflect their interests and passions, and feel a sense of community with others. Despite these many great possibilities, there is a need for young people to be better equipped to navigate their connected, constantly changing, digital world.
Several programs have been developed and implemented in schools to address this need. The concern with these programs, however, is that many are not evidence-based, nor has their impact been robustly evaluated. Digital Compass is an 8-week evidence-based program designed to support the ethical development of teenagers in a world of technological change. The program has been developed by The Behavioural Insights Team in collaboration with the Vincent Fairfax Family Foundation and The Alannah and Madeline Foundation.
The aim of the current project is to understand whether the Digital Compass program can help to support the ethical development of teenagers, particularly in the online environment. To do so, we have designed a study to evaluate the effectiveness of Digital Compass on teenagers’ self-reported online ethical behaviour. Our primary outcome variables are self-reported prosocial behaviour online, antisocial behaviour online, and attainment of goals related to ethical development identified during the program.

Experimental Details


Digital Compass is an 8 week program, targeting Year 9 students, delivered in schools weekly during a 40 minute workshop, by an external facilitator. Digital Compass aims to change online ethical behaviour by helping young people to; self reflect, determine acceptable online social norms, develop their self efficacy to intervene in online conflicts, control their online environment and identify and change online behaviours. The workshops involve online and offline evidence-based exercises, facilitated discussion and personalised online behaviour data compared to their peers to help them identify areas of change.

Digital Compass is designed to provide developmentally and cognitively appropriate support for young people to improve their ethical online behaviour, and build the skills required to navigate the online environment on their own.

Primary Outcomes

Primary Outcomes (end points)
There are two primary outcomes:

1. Did the Digital Compass program impact the students’ prosocial online behaviour?
2. Did the Digital Compass program impact the students’ anti-social online behaviour?
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
The secondary outcomes are listed below:

Did the Digital Compass program impact the students’ self-reflection?
Did the Digital Compass program impact the students’ self-efficacy in relationships?
Did the Digital Compass program impact the students’ empathy?
Did the Digital Compass program impact the students’ judgment of moral vignettes?
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
This study will be conducted as a cluster Randomised Controlled Trial, randomised at the class level. Year 9 classes within participating schools will receive the intervention. We will conduct pre- and post-intervention at all schools, to index change in the intervention group, and compare with any change in the control group. This design will allow us to understand the causal impact of the Digital Compass intervention on our key outcomes, but will not be powered to estimate whether the causal impact differs across different demographic groups.

We will randomise at the classroom level, with randomisation taking place before the launch of the intervention. BIT will be responsible for the randomisation. Participants will not be blind to the condition they are in, as those in the intervention group will receive the Digital Compass workshops and those in the control group will not.
Experimental Design Details
Randomization Method
Randomisation will take place via randomisation functions built into R statistical software
Randomization Unit
The randomisation will take place at the class-level.

Experiment Characteristics

Sample size: planned number of clusters
We plan to implement the intervention in 20 classes, and all additional classes within the schools recruited will serve as control classes (completing data collection activities only) and will make up the bulk of the comparison group.
Sample size: planned number of observations
We plan to implement this intervention in 20 classes, which will be approximately 500 individuals. Assuming that there are approximately three year 9 classes within each school, we will have approximately 1000 individuals in the control group.
Sample size (or number of clusters) by treatment arms
We plan to have 20 classes in the treatment, and with the assumptions detailed above, approximately 40 classes in the control.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
We have conducted a power calculation for a number of scenarios for our primary outcome measures, which are continuous survey measures. We believe that this measure will be the most difficult to power of our outcome measures, given the potential for floor effects for these measures (particularly the antisocial measures). Below are the assumptions for our power calculations: ● Significance level: 0.05 ● Power: 80% ● Number of participants: 500 in treatment, and 1000 in control ● Number of treatment arms: 2 (intervention, control) ● Standard deviation of measure: 4, 8, 10 ● ICC: 0.1 With 2 arms, we will be powered to detect between a 1 and 3 point difference in the average value of the scale given our assumptions. Given that the scales are out of 40 or 44, this represents a 2 - 7% increase in the scale. We believe that this trial is adequately powered to investigate our research question, as a difference smaller than this is not policy relevant.
