Primary Outcomes (explanation)
We measure emotional awareness, a student's ability to identify and verbally share their own emotions, using a shortened Emotional Awareness Questionnaire that covers the differentiating-emotions and verbal-sharing subscales (Rieffe et al., 2008). We capture emotion regulation with the Emotion Regulation Questionnaire for Children and Adolescents (Gullone and Taffe, 2012). Subjective wellbeing, the child's recent emotional state and positive outlook over the prior two weeks, is measured with the Stirling Children's Well-being Scale (Liddle and Carter, 2015), dropping its built-in social-desirability items, which we capture separately. We measure curiosity using items adapted from Alan and Mumcu (2024), and creativity through an alternative-uses task in which students are given an everyday object and have two minutes to list as many uses for it as they can (Guilford, 1967). We measure prosocial behaviour through a stated willingness to help others and a hypothetical sharing decision in which the student allocates a gift of ten chocolates between themselves and a peer who received none (Falk et al., 2018; Kosse et al., 2020). We additionally measure students' social behaviour as rated by their teacher, using an adapted short form of the Social Behavior Questionnaire (SBQ; Tremblay et al., 1991; Collet et al., 2023), covering the prosocial behaviour, disruptive behaviour, and hyperactivity-inattention subscales; the teacher responsible for the Grade 6 art period rates a random subset of students per class, drawn from the baseline enrolment roster, and this measure is collected at endline only. Each scale is scored following its source instrument, with the indicated items reverse coded so that higher values denote more of the outcome being measured, and then standardized so that treatment effects are expressed in control-group standard deviations.
