title: What do psychiatric patients believe regarding where control over their illness lies? Validation of the multidimensional health locus of control scale in psychiatric outpatient care.
abstract: Patients' perceived control constructs are important factors moderating health-related behaviors. We established the psychometric properties of the Spanish version of the Form C Multidimensional Health Locus of Control Scale (C-MHLC) and assessed the usefulness of these measures in the clinical setting. A cross-sectional survey querying about patients' health locus of control (HLOC) beliefs was offered to 607 psychiatric outpatients, of whom 507 accepted. The C-MHLC scale and the General Perceived Self-Efficacy Scale were completed. The psychiatric patients believe that their psychiatrist plays a crucial role in improving their state of health. The men scored higher than the women in internal dimension; the women scored higher in other people external dimension. Age, treatment time, and number of psychoactive drugs used showed significant differences in HLOC dimensions. Self-efficacy correlated positively with internal dimension and negatively with external dimensions. The results showed the validity of the four-factor structure of the Spanish version of the C-MHLC.
