SuperCAP Program to Improve Cognition and Daily Functioning in Post-COVID-19 Condition

The goal of this study is to determine whether the SuperCAP intervention program is superior to control in reducing disability from baseline to the post-intervention assessment in people with Post-COVID-19 Condition. The main question it aims to answer is whether participants assigned to SuperCAP experience a greater reduction in disability, defined as an improvement of at least 5 points on the WHODAS 2.0 from baseline to the post-intervention visit, compared with participants in the control group. Participants assigned to the SuperCAP intervention will undergo a series of sessions that include psychoeducation, adaptive cognitive training exercises, fatigue self-management strategies, and multidisciplinary content.

Inclusion Criteria: * Diagnosis of PCC, defined as the presence of three or more symptoms associated with COVID-19 infection for at least three months, not explained by other diseases. * Age 18 to 65 years. * Willingness to participate in an app-based intervention program aimed at improving daily Functioning in People Living with PCC. * Evidence of patient-reported cognitive difficulties emerging after COVID-19, operationalized as a WHODAS 2.0 Cognition Domain (D1) score \> 6 at baseline via RedCAP. * Digital proficiency defined as scoring ≥4 on MDPQ-16 item 2a (sending emails) and ≥3 on item 6a (using the device's app store) via RedCAP. * Self-reported ability to use a mobile application for approximately 15 minutes per day, 5 days per week, considering their current symptoms. * Possession of a personal smartphone compatible with the study mobile application (eSalut), with sufficient storage space and operating system version required for installation. Exclusion Criteria: * Inability to undergo neuropsychological tests or additional assessments. * Prior use of the SuperCAP program. * Current participation in a trial or program aimed at improving PCC symptoms. * Any condition that, in the investigator's opinion, could make participation unsafe, complicate interpretation of study results, interfere with achievement of study objectives, or otherwise affect the participant's ability to complete the study.
