A method, computer-readable media, and system associated with psychiatric and physiologic monitoring of a patient having PTSD or anxiety-related mental health conditions are provided. For example, data associated with a survey or questionnaire that was provided to a patient is received. A score may be determined from the data associated with the survey or questionnaire. A time-series is formed using heart-rate measurements detected by a sensor. Fractal properties, such as a Hurst exponent, may be calculated for the time-series. The score may be contextually matched to a set of reference scores. Further, the contextual matching may be used to determine a range of normative HRV values for determining whether a value associated with the patient is within the range. If the value associated with the patient is not within the range, a notification may be provided.
