ABSTRACT
Most existing measures of persecutory ideation (PI) rely on infrequent in-person visits, and this limits their ability to assess rapid changes or real-world functioning. Mobile health (mHealth) technology may address these limitations. Little is known about passively sensed behavioral indicators associated with PI. In the current study, sixty-two participants with schizophrenia spectrum disorders completed momentary assessments of PI on a smartphone that also passively collected behavioral data for one year. Results suggested that PI was prevalent (nâ¯=â¯50, 82% of sample) but had infrequent incidence (25.2% of EMA responses). PI was also associated with changes in several passively sensed variables, including decreases in distance traveled (Mkilometersâ¯=â¯-1.20, SDâ¯=â¯18.88), time spent in a vehicle (Mminutesâ¯=â¯-4.15, SDâ¯=â¯49.59), length of outgoing phone calls (Mminutesâ¯=â¯-0.79, SDâ¯=â¯13.13), time spent proximal to human speech (Mminutesâ¯=â¯-6.26, SDâ¯=â¯153.03), and an increase in time sitting still (Mminutesâ¯=â¯4.04, SDâ¯=â¯94.69). The present study suggests changes associated with PI may be detectable by passive sensors, including reductions in moving or traveling, and time spent around others or in self-initiated phone conversations. These constructs might constitute risk for PI.
