The ISO principle suggests that emotional regulation can be supported by gradually modifying the emotional characteristics of music to help individuals transition to a desired emotional state.\n\nParticipants in this study will be randomly assigned to either a music intervention group or a control group. The intervention group will receive personalized music playlists designed to help reduce stress, anxiety and depression. The control group will not receive any music intervention during the same period.\n\nOutcomes will be measured using self-report questionnaires assessing stress, emotional state, and well-being. The study is designed to contribute to the development of accessible, non-invasive stress management tools using music as a behavioral intervention.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '45 Years', 'minimumAge': '20 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Has completed education at the associate degree level or higher\n* Has at least one year of stable full-time work experience\n* Maintains a regular and stable daily routine\n\nExclusion Criteria:\n\n* Current or recent use of medication or history of surgical treatment\n* History of psychiatric disorders\n* Hearing impairments\n* Female participants who are currently pregnant or breastfeeding'}, 'identificationModule': {'nctId': 'NCT07055061', 'acronym': 'ISO4SAD', 'briefTitle': 'An ISO Principle-Based Music Intervention for Reducing Stress, Anxiety, and Depression', 'organization': {'class': 'OTHER', 'fullName': 'Shanghai Mental Health Center'}, 'officialTitle': 'An ISO Principle-Based Music Intervention for Reducing Stress, Anxiety, and Depression', 'orgStudyIdInfo': {'id': 'THU0420251002'}, 'secondaryIdInfos': [{'id': '62101324', 'type': 'OTHER_GRANT', 'domain': 'the National Natural Science Foundation of China'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'ISO Group', 'description': "Participants in this group will receive a music intervention based on the ISO principle.
