Involuntary mental time travel (MTT) refers to the phenomenon of mentally reliving past experiences or pre-living possible future events in an involuntary form. Few studies have explored involuntary MTT in individuals with schizotypal personality features. The present study aimed to first explore the psychometric properties of the Involuntary Autobiographic Memory Inventory (IAMI) in a Chinese sample (Study 1), and then to explore whether individuals with schizotypal personality features experience involuntary MTT more frequently than individuals without schizotypal features. Moreover, the study explored whether the aberrant frequency of involuntary MTT is correlated with positive schizotypal features (Study 2). The results showed that the IAMI had good structural validity and reliability in a Chinese sample. Individuals with schizotypal traits reported a significantly higher frequency, less positive emotion, and stronger emotional intensity for both involuntary memories and future thoughts compared with individuals without schizotypal features. Further analyses in individuals with schizotypal personality features showed that the frequencies of both involuntary memories and future thoughts were significantly correlated with positive schizotypal traits. These results have potential theoretical and clinical implications for a comprehensive understanding of involuntary MTT among individuals with schizotypal personality features.
