What was the primary aim of the study?
To test whether ABBI produces greater 24 month percent weight loss than SBT
What was the research design for this study?
randomized controlled trial, longitudinal repeated measures
Over the 12 months treatment period, how many treatment sessions did participants attend?
32 sessions
After the 12 month treatment period, how much contact did the participants have with researchers through month 24?
There was no contact between month 12 and the final assessment at month 24
What was the main inclusion criteria for participants in this study?
Overweight or obese, and high internal disinhibition
What primary measures did the researchers use to measure eating behaviors and internal disinhibition?
Eating Inventory
What was the primary outcome measure that was collected at follow-up assessments (baseline, 6, 12, 18, 24 months)?
Percent weight change
To ensure accuracy of the treatment delivery, sessions were rated for treatment fidelity. What was the intraclass correlation coefficient?
.92
True or False: ABBI showed statistically significant superiority over SBT on the primary 24 month percent weight-change assessment?
False
When did the researchers observe the greatest impact of ABBI?
Post intervention, between 18-24 months
True or False: The ABBI group regained a significant amount of weight during the post-treatment phase?
True
Which treatment (ABBI and SBT) had a significant effect on internal disinhibition? Were there differences between the two treatments?
Both treatments led to significant reductions in internal disinhibition, no significant differences between the two
Name one strength of the study.
:)
Name one weakness of the study.
:(
Was this study generalizable? Why or why not?
Limited generalizability - 85% female, 88% Caucasian, primarily from one region
The authors imply that there is a mechanism measurement gap related to ABBI (ACT) in their study. What does this mean?
when a phenomenon is not fully understood because the mechanisms cannot be adequately observed or measured
