Schizophrenia, bipolar disorder and major depression are associated with nonadherence registered mean figures of around 50%, highlighting the relevance of having simple adherence tools to incorporate into daily clinical practice. For 10 years we have focused on self-report as an assessment method and have studied thousands of outpatients taking thousands of psychiatric medications in three countries. Measurement of treatment adherence during use of polypharmacy is a really complex task as patients could adhere differently to the various medications prescribed, making it essential to assess adherence to each individual medication. This was not possible until the introduction of the Sidorkiewicz Adherence Tool that allows one to separate adherence to each medication, whether poor or not. Health psychologists have developed the Health Belief Model which has not received enough attention by psychiatrists. Based on this model, we have focused on personality styles and specific beliefs concerning specific medications as possible predictors of poor adherence. We developed the Patient Health Beliefs Questionnaire on Psychiatric Treatment which provides 5 self-reported personality dimensions: negative aspects of medication (pharmacophobia), positive aspects of medication (pharmacophilia), high/low psychological reactance, high/low doctor health locus of control (HLOC) and high/low internal HLOC. Based on the Beliefs about Medicines Questionnaire we have developed a measure of skepticism, defined as a patient’s high concern about adverse reaction to an individual medication and a low belief in its necessity. Our research experience based on the tools for assessing and predicting adherence is presented in a practical manner by using seven boxes and examples.
