1) The cognitive intervention is a 4-session, psycho-educative, integrative and multidimensional intervention designed to prevent post-acute cognitive symptoms. Each individual session will last 90' and will concern a specific cognitive domain:

• Cognition in covid, fatigue and sleep
• Working memory and attentional functioning
• Executive functioning
• Memory functioning

The structure of the sessions will be similar: (1) explanation about (dys)functioning of processes associated to the domain of interest: (2) identification of problems in daily life translated into functional objectives (e.g. keeping papers organized; scheduling activities to avoid fatigue); (3) discovery and application of (meta)cognitive strategies.

Material (videos, tips,…) will be provided that the patients can consult when needed. The patients will have a diary to complete to explain when they applied the content of the intervention in daily life, and how successful it was.

2) The affective intervention is also a psychoeducation program based on four sessions, in which different strategies and resources will be proposed to increase self-efficacy for emotion management:

• Recognizing emotions and affective states
• Accepting and communicating emotions and difficulties
• Accepting the uncertainty associated with difficulties
• Behavioural activation

Material (videos, tips,…) will be provided that the patients can consult when needed. The patients will have a diary to complete to explain when they applied the content of the intervention in daily life, and how successful it was.

Psychoeducation refers to the process of providing education and information to those seeking or receiving mental health services.

Subjective report of difficulties experienced by patients in daily life: BRIEF (Behavioral Rating Inventory of Executive Function) and MMQ (Multifactorial Memory Questionnaire) questionnaires.

The BRIEF summary index scales (Behavioral Regulation Index and Metacognition Index) and the scale reflecting overall functioning (Global Executive Composite) are expressed at t-scores (M=50, SD=10) ranging from 30 to 100. Higher scores indicates better outcome.

There are three scales in the MMQ : Satisfaction Scale, Ability Scale and Strategy Scale. The individual score will range from 0 to 72, from 0 to 80 and from 0 to 76 respectively for each scale. Higher scores indicate better ratings.

Subjective report of difficulties experienced by patients in daily life: scores from BRIEF and MMQ questionnaires

The BRIEF summary index scales (Behavioral Regulation Index and Metacognition Index) and the scale reflecting overall functioning (Global Executive Composite) are expressed at t-scores (M=50, SD=10) ranging from 30 to 100. Higher scores indicates better outcome.

There are three scales in the MMQ : Satisfaction Scale, Ability Scale and Strategy Scale. The individual score will range from 0 to 72, from 0 to 80 and from 0 to 76 respectively for each scale. Higher scores indicate better ratings.

Scores at the WPAI (Work Productivity and Activity Impairment) scale. WPAI outcomes are expressed as impairment percentages (0-100), with higher numbers indicating greater impairment and less productivity.
