Sponsor's own description

The Positive Affect Regulation sKills (PARK) Course is an online program containing a series of positive emotion skills for individuals experiencing stress and distress as a result of COVID-19 and the return to "normal." The study specifically targets positive emotion, and offers an array of skills in a self-guided online delivery platform, making the program accessible and convenient in confusing and stressful times. Our main aims are: Aim 1: To explore the effects of PARK on anxiety, depression, feelings of social isolation, positive affect, and a sense of meaning and purpose. Aim 2: To test whether age or gender moderate the effects of the program.
