Research Design & Number of Studies
The best evidence for The Body Project for persons aged 13-18 years comes from two internally conducted randomised controlled trials (RCTs) (Stice et al, 2006/ Stice et al, 2008; Stice et al 2009), and one RCT conducted in collaboration with the programme developer (Ghaderi et al, 2020). The first study included 481 high school and university girls aged 14-19 years (mean age of 17 years) (Stice et al, 2006/ Stice et al, 2008). The second RCT included 306 high school adolescent girls aged 14-19 years (mean age 15.7 years) (Stice et al, 2009). The third study included 443 young women aged 15-20 years. All three RCTs included participants with body image concerns, and two of the three studies included ethnically diverse participants, including African American, Caucasian, Asian/Pacific Islander, Hispanic, and other mixed racial heritage (Stice et al, 2009; Stice et al, 2006/Stice et al 2008)
Outcomes Achieved
Compared to assessment only control groups who did not receive the intervention, the following outcomes were observed:
Child Outcomes
- Significantly greater reduction in thin-ideal internalisation at post-test (Ghaderi et al, 2020; Stice et al, 2009), sustained at 6 months follow-up and at 1-year (Ghaderi et al, 2020; Stice et al, 2006), at 18 months follow-up (Ghaderi et al, 2020), and 2-year follow-up (Ghaderi et al, 2020; Stice et al, 2008)
- Significantly greater reduction in body dissatisfaction at post-test (Ghaderi et al, 2020; Stice et al, 2006; Stice et al, 2009), sustained at 6 months (Ghaderi et al, 2020; Stice et al, 2006; Stice et al 2009), at 1-year follow-up (Ghaderi et al, 2020; Stice et al, 2009), at 18 months follow-up (Ghaderi et al, 2020), at 2-year follow-up (Ghaderi et al, 2020; Stice et al, 2008), and 3-year follow-up (Stice et al, 2008)
- Significantly greater reduction in dieting at post-test (Stice et al, 2006; Stice et al, 2009), sustained at 6 months and 1-year follow-up (Stice et al, 2006)
- Significantly greater reduction in negative affect at post-test (Stice et al, 2006), sustained at 6 months follow-up (Stice et al, 2006), and at 2-year and 3 year follow-up (Stice et al, 2008)
- Significantly lower bulimic symptoms/ eating disorder symptoms at post-intervention, sustained at 6 months and 1-year follow-up (Ghaderi et al, 2020; Stice et al, 2006; Stice et al, 2009), at 2-year follow-up (Ghaderi et al, 2020; Stice et al, 2008), and at 3-year follow-up (Stice et al, 2008)
- Significantly lower psychosocial impairment at 2-year follow-up, sustained at 3-year follow-up (Stice et al, 2008)
- Significantly greater reduction in clinical impairment at post-intervention, sustained at 6-month follow-up (Ghaderi et al, 2020)
