Table 3. Bootstrapped confidence intervals (CIs) for each variable as mediators of the relationship between prior success with dietary change and end-of-treatment outcome.

	95% CI	p-value
Model 1 (Baseline variables)
TSRQ – Autonomous motivation	(-0.19, 0.34)	.79
TSRQ - Amotivation	(-0.38, 0.26)	.89
WEL - Negative Emotion	(-0.74, 0.23)	.39
WEL - Physical Discomfort	(-0.20, 0.87)	.29
Model 2 (Change during treatment)
WEL - Negative Emotion	(-1.36, 0.13)	.16
WEL - Physical Discomfort	(-0.88, 0.51)	.53
Attendance	(-1.81, -0.17)	.03

All models include gender as a covariate. Model 2 utilizes change from baseline to mid-treatment (six months) as a mediator of end-of-treatment (one year) outcome.
