This study aims to assess the relations among our daily thought patterns, positive emotions, everyday experiences, and cognitive functioning abilities. Eligible participants will complete a series of online questionnaires, a short 15- to 25-minute psychological interview, and brief cognitive functioning tests at Day 1 and Day 16. All visits will occur via Zoom. In between study visits on Day 1 and Day 16, they will be prompted to complete smartphone-delivered assessments of cognitive functioning, symptoms, and experiences for 14 days, 5 times a day. This is important to inform clinicians and researchers on how best to develop effective digital mental health therapies.

During Day 1, participants will undergo a brief 15- to 25-minute clinical interview over Zoom. After the clinical interview, if participants meet the study eligibility criteria, we will continue with the procedures outlined below. Otherwise, if they are ineligible for the study, we will mention that this study is not suitable for them and provide the contact of mental health treatment services. Eligible participants will then conduct a series of self-report questionnaires and performance-based cognitive functioning tests for the next 35 minutes. Participants will then complete a series of 14-day brief ecological momentary assessments administered on their smartphone five times a day, for 14 days. Last, participants will return for a 35- to 45-minute visit on Day 15 to complete a series of self-report questionnaires and performance-based cognitive functioning tests.
