One of elements of motivational interviewing counselling is supporting self-efficacy. Models such as Roger’s
Protection Motivation Theory explain how an individual’s self-efficacy, their perception of their own susceptibility
to a health problem and the severity of their condition, affect the extent to which changes are made [12]. Several
studies suggest self-efficacy increases over the course of obesity treatment [4,5,13]. Bas and donmz [5] note that
treatments that improve self-efficacy may help participants lose more weight during treatment and future obesity
treatment programs should consider including approaches that directly strengthen self- efficacy and promote weight
loss simultaneously.
