Brief summary

The overall aim for this project is to conduct a randomised controlled trial to examine the efficacy of GoodForm, an education program that aims to reduce body dissatisfaction, appearance and performance enhancing substance [APES] use, and lenient attitudes towards doping in sport) in 600 boys aged 14-5. This program will run within the Health and Physical Education curriculum. Boys have typically been overlooked in body image research, and there are no effective intervention programs for boys. There is evidence that body image, the use of supplements, and attitudes towards doping in sport are interrelated and contribute to anabolic steroid use in adolescent boys. The theoretical frameworks underpinning body image and intentions to use supplements are very different for boys and girls. We will focus only on boys in order to confirm approaches that can be used to target these behaviours in a single sex setting to fill this gap in the literature. In this research, we will ask teachers of grade 9 and 10 boys to implement GoodForm, the 4 session program that we have developed. We will measure body image, use and intentions to use APES, and attitudes towards doping in sport before and after boys receive the program to determine impact. This is the first trial of an antidoping program that targets the behaviours that might lead to boys using muscle-building supplements in the world.

Interventions

OVERVIEW Goodform is a 1 hr x four weekly sessions educational program for boys aged 14-15 aimed at improving body image, reducing positive attitudes towards doping in sport, and reducing intentions to use appearance and performance enhancing substances (APES). The program is based on two highly successful existing programs; ATLAS (Goldberg et al., 1996) and The Body Project (Stice et al., 2000), and uses a dissonance-based approach and a social norms approach to achieve outcomes.

OVERVIEW Goodform is a 1 hr x four weekly sessions educational program for boys aged 14-15 aimed at improving body image, reducing positive attitudes towards doping in sport, and reducing intentions to use appearance and performance enhancing substances (APES). The program is based on two highly successful existing programs; ATLAS (Goldberg et al., 1996) and The Body Project (Stice et al., 2000), and uses a dissonance-based approach and a social norms approach to achieve outcomes. The intervention will be delivered by Health and Physical Education (HPE) teachers of boys in year 9, during weekly face to face HPE classes at participants' schools. All teachers will receive a facilitator workbook (specifically designed for this program) with structured activities and explanations for how to deliver the program. Attendance of participants will be monitored using attendance sheets each lesson. Adherence to session content will be monitored using a self-report checklist completed by the teacher following each lesson. The intervention will take place over the course of four HPE classes. Each lesson will cover a set of structured activities. Session 1 introduces cultural ideals around appearance, and helps boys learn to challenge these ideals. Session 2 introduces supplements and steroids, and helps boys learn about the social, financial, and health risks of these substances. Session 3 is structured around critiquing the use of APES and developing strategies to argue against using them. Session 4 takes an advocacy-based approach, with boys presenting a campaign against one of four types of APES, and identifying ways they can advocate against APES in their everyday lives. Sessions 2-4 take a Jigsaw approach to learning. The classroom will be split up into four groups, with each group learning about a different APES in each activity, so that eventually all boys have learned about each substance. MATERIALS Facilitator workbook - teachers all receive a facilitator workbook (designed specifically for this study) that explains the theoretical basis and evidence for the program's activities, and how to facilitate all activities. The workbook can be accessed by emailing the researchers. Student workbook - students receive a student workbook (designed specifically for this study), in which the majority of activities are completed. The workbook contains 10 worksheets, completed throughout the four intervention sessions. The workbook can be accessed by emailing the researchers. Digital cultural ideal tool - Found at http://goodform.org.au/ - this tool introduces boys to the cultural ideal in session 1. Videos - Five videos have been developed for Goodform. Four focus on the risks of using APES, and are used for boys to learn about these substances.
