Final answer:
Ashley, who faded the program out over 6 weeks, is most likely to have sustained behavior change after one year, due to the gradual adaptation to change. The correct answer is option b.
Step-by-step explanation:
Out of the students who met their final daily behavioral goal, Ashley, who slowly faded the program out over a period of 6 weeks following the project, is most likely to have maintained their behavior change one year later. This is because the gradual reduction of program support can lead to more sustainable behavior change compared to an abrupt end.
Mo, who stopped following the program immediately, Dee, who maintained it for only an additional week, and Myya, who planned to maintain the program forever, likely have less realistic or sustainable approaches to long-term change
