Table 3. Hypothesis 3: LS group comparisons.

Group	N	Mean	SD	p
Underweight	17	27.50	12.00	<.001*
Healthy Weight	190	22.22	15.51
Overweight	57	17.71	16.85
Obese	42	6.71	15.97
Extreme Obesity	19	5.76	13.99
Total	341	18.86	16.69
Mean Lifestyle Scores Between Recent Weight Trajectory
Weight loss	161	32.33	19.01	<.001
Weight Maintenance	543	21.50	15.52
Weight Gain	210	12.98	16.30
Total	914	21.45	17.45
Mean Lifestyle Scores Between Weight Management Success and No Success
No Success	375	13.68	14.95	<.001
Success	537	26.92	17.03
Total	912	21.45
Mean Lifestyle Scores of Continued Success or Weight Regain**
Weight Regain	69	15.20	17.49	<.001
Continued Success	146	32.13	17.04
Total	215	26.70	18.88

Note: *t-tests did not reveal significant differences between underweight, healthy weight, and overweight participants. A t-test between obese and extreme obesity was p = .05.

** Continued Weight Management Success was determined by participants having lost at least 5% of their initial body weight and a report of weight maintenance or continued weight loss. The weight regain group was determined as participants who reported previous weight loss but have reported recent weight gain.
