Abstract Introduction  The Multidimensional Weight Locus of Control Scale (MWLCS) measures a person’s beliefs regarding the locus of control or lack of locus of control over his/her body weight. Purpose  We aim to evaluate the factorial structure and psychometric properties of the MWLCS with Spanish normal weight, overweight and obese samples. Methods  The research was carried out in two different studies. The first included a sample of 140 normal weight participants, selected out of a 274 sample recruited with an online survey. Study 2 was carried out in a sample of 633 participants recruited from the PREDIMED-Plus study.
