Using Experience Sampling Methodology Data to Characterize the Substance Use of Youth With or At-Risk of Psychosis.

Objectives: Psychotic-spectrum disorders emerge during adolescence and early adulthood, which corresponds with the peak period for substance use initiation. Clinical and epidemiological data provide support that substance use is associated with psychotic symptom onset and severity. Experience-sampling methodology (ESM) data may provide additional insight into dynamic associations between substance use and psychotic symptoms.

Emotional and stigma-related experiences relative to being told one is at risk for psychosis.

Objective: Despite the appeal of early intervention in psychosis, there is concern that identifying youth as having high psychosis risk (PR) may trigger stigma. This study employed a pre-post design to measure change in PR participants' emotions about PR upon being told of their PR status and according to whether this was the first time receiving this information.

Methods: Participants (n = 54) identified as at PR via structured interview rated their emotions about PR before and after being told they were at PR.
