RESUMEN
The COVID-19 pandemic has induced traumatic and fear responses globally. Time attitudes, which refer to one's feelings toward the past, present and future, may have certain effects on psychological adaptations during this crisis period. This study employed a person-centered approach and a two-wave prospective design to investigate how people with different time attitude profiles change differently in their PTSD symptoms and COVID-19-related fears from a low-risk stage to the first big COVID-19 outbreak in Taiwan. Participants were 354 adults with a mean age of 27.79 years. The result provided support for the theoretical six-factor structure of the traditional Chinese Adolescent and Adult Time Inventory-Time Attitudes Scale (AATI-TA). Four clusters of time attitude profiles were identified (Positives, Negatives, Past Negatives and Pessimists). At both waves, Positives had lower levels of PTSD severity and COVID-19-related fears than most of the other groups, and the reverse was noted for Negatives. As for time effects, people across all profiles were significantly affected during the outbreak, but Negatives showed a greater increase in PTSD severity than other groups. In conclusion, mental health services should put efforts into early identification of those with highly negative time attitudes and implement interventions that nudge people toward a more balanced or positive attitude in each temporal frame, especially during adversity such as the COVID-19 pandemic.
