Soeharto Heerdjan Psychiatric Hospital. The sampling data collection technique uses probability. Data were collecte using questionnaire with a reliability value for knowledge about schizophrenia (KASQ) of 0.945, informational support 0.935, assessment/award support 0.915, emotional 0.907, and medication adherence (MARS) 0.960. Bivariate data analysis using logistic regression and multivariate data  using the multiple logistic regression test. Results: The research result showed that the majority of respondents had insufficient knowledge 47.3 % with a p-value of  0.000 that there was a significant relationship between family knowledge about schizophrenia and adherence to taking medication.  Informational support is 66.7% lacking with a p-value 0.000 a significant relationship between infomational support and medication adherence.
