Can a lifestyle intervention impact self-efficacy of men on ADT?

Effects of a Lifestyle Intervention on Select Social Cognitive Outcomes in Prostate Cancer Patients Undergoing Androgen Deprivation Therapy

It is thought that a person’s evaluations of himself and his sense of self-efficacy can play a role in “lifestyle behavior change” outcomes, including changes in diet and exercise behaviours.

In a recent (2018) pilot study, researchers sought to investigate the impacts of a group-based cognitive-behavioural intervention on certain social cognitive factors like self-efficacy.   

The Individualized Diet and Exercise Adherence-Pilot (IDEA-P) utilized a group cognitive-behavioural approach to offer a combined diet and exercise intervention. 

32 men who were on ADT for prostate cancer were randomly assigned to one of two groups: 1) an intervention group, in which participants took part in a group-based cognitive-behavioural diet and exercise intervention; 2) a control group, in which participants received standard of care (no intervention). 

After two months, the investigators assessed certain social-cognitive outcomes, including self-efficacy, self-regulatory behaviours, and satisfaction with physical function. 

The group-mediated cognitive behavioral intervention was associated with “superior changes” in self-efficacy and satisfaction with physical function.

Although preliminary, results of this pilot trial suggest that a group-based cognitive-behavioural intervention has the potential to meaningfully support men as they implement changes in diet and exercise behaviours.
