Self-Directedness Predicts Quality of Life in Individuals with Psychotic Experiences: A 1-Year Follow-Up Study

There is a high prevalence of psychotic-like experiences in nonclinical patient cohorts from Brazil. This study aimed to test whether personality dimensions, as well as schizotypy, are important predictors of quality of life (QoL) in individuals with psychotic experiences (PE).

METHOD: 115 participants were recruited from Spiritist Centers in Brazil. At the 1-year follow up, 90 participants (78%) were reassessed. Instruments were the SCID-I (Structured Clinical Interview for DSM-IV), TCI-R 140 (Revised Temperament and Character Inventory), OLIFE-R (Oxford-Liverpool Inventory of Feelings and Experiences), and WHOQOL-BREF (World Health Organization QoL Instrument).

RESULTS: Mean age (±SD) was 36.8 (±12.5) years; 70% were female. Participants reported 74.4% of PE at time 1 and 72.3% at time 2. At time 1, temperament and character explained 47% of the psychological QoL variance; self-directedness was the strongest predictor of higher QoL, while harm avoidance and introverted anhedonia predicted worse QoL. At the 1-year follow-up, self-directedness remained the most important predictor of psychological QoL.

CONCLUSION: Individuals reporting PE can show psychological QoL when they are high on self-directedness. Those with high levels of introverted anhedonia and cognitive disorganization can have a lower QoL and may be at risk for mental health problems.
