Which factor is least likely to facilitate behavior change?

The factor that is least likely to facilitate behavior change is intangible rewards for behavior modification. While rewards can play a significant role in motivating individuals to change their behavior, intangible rewards—such as emotional satisfaction or a sense of achievement—may not provide the same level of immediate reinforcement as more tangible and concrete incentives.

Behavior change is often supported by clear, observable outcomes or benefits that individuals can easily recognize and appreciate. Tangible rewards, like direct feedback or financial incentives, tend to be more effective because they create a more immediate connection to the desired behavior. In contrast, intangible rewards may not provide enough motivation or may be harder for individuals to perceive and quantify as beneficial for their journey towards behavior modification.

Frequent reinforcement of nutrition messages, peer group support, and time for group discussion are all strategies that have proven effective in promoting behavior change because they provide clear, consistent cues and social support that help individuals remain engaged and committed to changing their behavior.
