Brief summary

This study investigates how different ways of reflecting on emotions in daily life influence emotional awareness, emotion regulation, and mental health. Using the FeelSync mobile app over the course of seven days, participants are prompted multiple times a day to report on their current emotional state in various formats (e.g., rating scales, multiple choice, or free text). In some groups, participants also receive brief daily exercises designed to help them practice cognitive reappraisal-a strategy that involves reframing stressful situations to reduce their emotional impact. The study aims to assess not only the overall effectiveness of these reappraisal exercises but also whether the type of emotional self-report used before the intervention affects its impact. All participants complete questionnaires before and after the app phase to track changes in mood, stress, emotional awareness, and regulation.

DEVICEFeelSync mobile application

Ecological Momentary Intervention focused on cognitive reappraisal for distressing autobiographical memories, with a possibility to choose between distancing and positive reappraisal.

Design outcomes

Primary

MeasureTime frameDescription
State-Trait Anxiety InventoryBaseline (pre-intervention, study day 1) and Follow-up (post intervention, study day 9)Self-report questionnaire, \[state scale only\], Range: 20 - 80 Higher scores: Worse outcome (greater state anxiety)
Perceived Stress ScaleBaseline (pre-intervention, study day 1) and Follow-up (post intervention, study day 9)Self-report questionnaire, Range: 0 - 40 Higher scores: Worse outcome (higher perceived stress)
Beck Depression Inventory IIBaseline (pre-intervention, study day 1) and Follow-up (post intervention, study day 9)Self-report questionnaire, Range: 0 - 63 Higher scores: Worse outcome (more severe depressive symptoms)
Toronto Alexithymia ScaleBaseline (pre-intervention, study day 1) and Follow-up (post intervention, study day 9)Self-report questionnaire, Range: 20 - 100 Higher scores: Worse outcome (greater difficulties in identifying and describing feelings; lower emotional awareness)
Emotion Regulation QuestionnaireBaseline (pre-intervention, study day 1) and Follow-up (post intervention, study day 9)Self-report questionnaire, Reappraisal subscale: Range 1 - 7 (mean of 6 items) Higher scores: Better outcome (more frequent use of cognitive reappraisal) Suppression subscale: Range 1 - 7 (mean of 4 items) Higher scores: Worse outcome (more frequent use of suppression)
Cognitive Emotion Regulation QuestionnaireBaseline (pre-intervention, study day 1) and Follow-up (post intervention, study day 9)Self-report questionnaire, Subscale range: 2 - 10 per strategy Higher scores: On adaptive strategies (e.g., positive reappraisal, putting into perspective): Better outcome On maladaptive strategies (e.g., rumination, catastrophizing): Worse outcome

Secondary

MeasureTime frameDescription
Mobile Agnew Relationship MeasureFollow-up (post intervention, study day 9)Self-report questionnaire, Range: 16-112 Higher scores: Better outcome (stronger perceived therapeutic alliance with the app/intervention)
