Design and Setting: A randomized trial was conducted, initially recruiting 51 participants aged 65 and above from the Greek Association of Alzheimer\u2019s Disease and Related Disorders in Thessaloniki, Greece. The study employed a control-experimental group setup. To ensure randomization, each participant was assigned a unique number, and a random number generator was used for group allocation. Participants: A total of 41 eligible participants with amnestic mild cognitive impairment (MCI) were included in the study after screening. Intervention: The intervention consisted of a 3-week positive psychology program (PPI) where the PERMA Profiler questionnaire was administered at three intervals: pre-intervention, post-intervention, and one month after completion. Main Outcome Measures: The subjective well-being of participants. Results: The analysis, conducted mainly through mixed-measures ANOVAs, supported the study\u2019s hypotheses, revealing that the 3-week PPI led to increased PERMA model scores and overall well-being, which persisted even after one month. Conversely, non-participants experienced declines in most domains except for Positive Emotion and Meaning, which demonstrated improvement and recovery during follow-up. Conclusions: These findings suggest the potential of PPI in enhancing the subjective well-being of older adults with amnestic MCI, with implications for addressing dementia-related challenges. Further investigation is warranted to pinpoint PPI effects on MCI and tailor interventions for improved subjective well-being.<\/jats:p>","DOI":"10.3390\/bs13100838","type":"journal-article","created":{"date-parts":[[2023,10,13]],"date-time":"2023-10-13T10:16:12Z","timestamp":1697192172000},"page":"838","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Enhancing Subjective Wellbeing in Older Individuals with Amnestic Mild Cognitive Impairment: A Randomized Trial of a Positive Psychology Intervention"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0300-2560","authenticated-orcid":false,"given":"Konstantina","family":"Tsiflikioti","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Leiden University, 2333 ZA Leiden, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0527-7143","authenticated-orcid":false,"given":"Despoina","family":"Moraitou","sequence":"additional","affiliation":[{"name":"School of Psychology, Faculty of Philosophy, Aristotle University, 54124 Thessaloniki, Greece"},{"name":"Laboratory of Psychology, Department of Cognition, Brain and Behavior, School of Psychology, Faculty of Philosophy, Aristotle University, 54124 Thessaloniki, Greece"},{"name":"Laboratory of Neurodegenerative Diseases, Center for Interdisciplinary Research and Innovation (CIRI-AUTH), Balkan Center, Aristotle University, 10th km Thessaloniki-Thermi, 54124 Thessaloniki, Greece"},{"name":"Day Center \u201cGreek Association of Alzheimer\u2019s Disease and Related Disorders (GAADRD)\u201d, 54643 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christos","family":"Pezirkianidis","sequence":"additional","affiliation":[{"name":"Interdisciplinary Mental Health Centre of the Armed Forces Board of Members, Hellenic Association of Positive Psychology, Panteion University, 17671 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgia","family":"Papantoniou","sequence":"additional","affiliation":[{"name":"Laboratory of Psychology, Department of Early Childhood Education, School of Education, University of Ioannina, 45110 Ioannina, Greece"},{"name":"Institute of Humanities and Social Sciences, University Research Centre of Ioannina (URCI), 45110 Ioannina, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0380-2220","authenticated-orcid":false,"given":"Maria","family":"Sofologi","sequence":"additional","affiliation":[{"name":"Laboratory of Psychology, Department of Early Childhood Education, School of Education, University of Ioannina, 45110 Ioannina, Greece"},{"name":"Institute of Humanities and Social Sciences, University Research Centre of Ioannina (URCI), 45110 Ioannina, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2362-2094","authenticated-orcid":false,"given":"Georgios A.","family":"Kougioumtzis","sequence":"additional","affiliation":[{"name":"Department of Turkish Studies and Modern Asian Studies, Faculty of Economic and Political Sciences, National and Kapodistrian University of Athens, 15772 Athens, Greece"},{"name":"Department of Psychology, School of Health Sciences, Neapolis University, 8042 Pafos, Cyprus"},{"name":"School of Social Sciences, Hellenic Open University, 26335 Patras, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalini","family":"Tsolaki","sequence":"additional","affiliation":[{"name":"Laboratory of Neurodegenerative Diseases, Center for Interdisciplinary Research and Innovation (CIRI-AUTH), Balkan Center, Aristotle University, 10th km Thessaloniki-Thermi, 54124 Thessaloniki, Greece"},{"name":"Day Center \u201cGreek Association of Alzheimer\u2019s Disease and Related Disorders (GAADRD)\u201d, 54643 Thessaloniki, Greece"},{"name":"1st Department of Neurology, Medical School, Aristotle University of Thessaloniki (AUTh), 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Seligman, M.E.P., and Csikszentmihalyi, M.
