Momentary Assessment of Psychotic Experiences
Many researchers, clinicians, and clients know the pain of symptom interviews — they often take between 20-60 minutes, which can be very draining! Additionally, the current self-report measures for psychotic symptoms ask people if they've experienced psychosis in the last week, month, or even lifetime; but none ask what people are experiencing right now in the moment. To address these gaps, I created a novel 30-item self-report measure that allows people to report their momentary psychotic experiences in around 3-5 minutes: the Momentary Assessment of Psychotic Experiences (MAPE). The MAPE can be used across the psychosis continuum, and has been validated in community samples and is currently undergoing validation in clinical samples.
If you'd like to use the MAPE or help with recruitment by posting flyers, please get in touch!
Social Behavior in Schizophrenia
Connecting with others is a huge part of our lives. It helps protect us from stress and boosts our overall well-being! But building and maintaining relationships isn’t always easy, and some people struggle with it more than others. To explore why some people have these difficulties, I'm studying social behavior in individuals with and without schizophrenia. By analyzing behavioral data, language patterns, and video recordings of social interactions, I hope to better understand which interpersonal patterns influence how comfortable and close people feel to each other—and whether these patterns look different in people with schizophrenia. My goal is to better understand what might make socializing difficult for people with schizophrenia and use this knowledge to improve social interventions.
