Description of intervention(s) / exposure
This trial contains three conditions (2 x active, 1 x control) aimed at children between the ages of 8-13. The active conditions are two prevention programs aimed to reduce worry, anxiety and depression, and improve resilience. Programs are delivered to classes (approx 20-30 participants) of students within school time. Programs consist of eight 50 minute sessions, delivered weekly by a provisional psychologist with a bachelor's (honours) degree in psychology, and a research assistant who is completing their bachelor's degree in psychology.

Arm 1 - Emotion Regulation (ER) program: the ER program consisted of three main components: 1) identifying and understanding one’s own emotions and the emotions of others, 2) becoming familiar with the relationships between thoughts, feelings, and behaviours, and how thoughts can affect emotion regulation, and 3) practical prevention strategies, such as the importance of healthy eating and exercise, and their effects on emotion regulation.

Arm 2 - Behavioural activation (BA) program: The BA program begins with learning about worry and avoidance, and the consequences of these factors on functioning. Children are then assisted with identifying their own patterns of avoidance behaviours, and encouraged to overcome such avoidance by constructing and practising alternative behaviours. Children are supported in setting short-term and long-term goals that align with positive outcomes, and are encouraged to develop practical behaviours that are in line with these goals.

Arm 3 - Control condition: children are assigned to a usual class control condition whereby they attend their regular scheduled classes (i.e., no program is delivered).

Adherence to the protocols by the provisional psychologist was monitored through the completion of a program fidelity checklist for a set of randomly selected sessions.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A researcher with no other involvement in the study generated a random block sequence for the allocation of schools to condition using IBM Statistical Package for the Social Sciences, Version 25 (IBM SPSS). The sequence contained twelve sets of ones, twos and threes, corresponding to ER, BA and control respectively. Schools were allocated to a condition after consenting to participate in the study, and neither schools nor participants were blind to their allocated condition.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software.

Efficacy
Statistical methods / analysis
A power analysis showed that to detect a Cohen’s d effect size of 0.3, with a power level of 0.80, 330 participants were required, with 110 participants per condition (Hedeker, Gibbons, & Waternaux, 1999).

Baseline differences between the three conditions were assessed using one-way analysis of variance (ANOVA) for each outcome variable. Change in symptomology for each outcome variable was assessed using Linear Mixed Models (LMM). LMMs are the recommended technique for analysing repeated measures designs as they can accurately account for correlation between repeated measures of the same participant, and are able to handle missing data and unequal groups (Gueorguieva & Krystal, 2004).

The mediating roles of resilience, level of emotion regulation, level of behavioural activation, and anxiety and depression were explored using the bootstrap method via the PROCESS macro for SPSS (Hayes, 2013). Compared to traditional regression analyses, which require a significant interaction between variables in order to run a valid analysis, the PROCESS macro is able to conduct a reliable analysis of mediation effects without this prerequisite (Hayes, 2013).
