Proactivity towards avoiding the usual aging process is needed. This study analyses the long-term effects of participation in Community-Based Programs on psychological well-being.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Method<\/jats:title>\n<jats:p>A sample of 150 community-dwelling participants enrolled in Community-Based Programs, aged 55 to 84 years and living in three Portuguese localities were matched by age (55\u201364, 65\u201374, 75\u201384 years), gender, and locality with a comparison group of non-participants. We administered a multidimensional gerontological protocol which included socio-demographic information, measures of health\/disease, functional ability, social network, cognitive performance and psychological well-being. Hierarchical regression models were used to test the effects of Community-Based Programs on psychological well-being adjusting for remaining variables.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Overall, psychological well-being is positively associated with household income and satisfaction with health. Nevertheless, in participants, psychological well-being builds predominantly upon social network and is not associated with a moderate inability or cognitive deficits, contrasting with psychological well-being in non-participants. After adjusting for background variables, psychological well-being was positively associated with health satisfaction and social network and negatively related to moderate inability. Further, a significant interaction of participation in Community-Based Programs with age, points out higher levels of psychological well-being in participants contrasting with a downward trend in non-participants. After stratification by age, psychological well-being increases with time attending Community-Based Programs in the oldest (75\u201384 years) contrasting with the remainder.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Participation in Community-Based Programs may improve the negative effects of the aging process on psychological well-being. This positive effect as age increases may be linked to a reinforcement of social network, valued more by participants in Community-Based Programs. Furthermore, the programs may act as a healing\/maintenance strategy in persons with moderate inability and\/or cognitive deficits.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0286115","type":"journal-article","created":{"date-parts":[[2023,5,19]],"date-time":"2023-05-19T17:32:43Z","timestamp":1684517563000},"page":"e0286115","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["Engagement with life and psychological well-being in late adulthood: Findings from community-based programs in Portugal"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7282-5480","authenticated-orcid":true,"given":"Alice","family":"Bastos","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7144-2960","authenticated-orcid":true,"given":"Joana","family":"Monteiro","sequence":"additional","affiliation":[]},{"given":"Raquel","family":"Barbosa","sequence":"additional","affiliation":[]},{"given":"Helena","family":"Pimentel","sequence":"additional","affiliation":[]},{"given":"Sofia","family":"Silva","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5168-3073","authenticated-orcid":true,"given":"Carla","family":"Faria","sequence":"additional","affiliation":[]}],"member":"340","published-online":{"date-parts":[[2023,5,19]]},"reference":[{"issue":"4","key":"pone.0286115.ref001","doi-asserted-by":"crossref","first-page":"366","DOI":"10.1037\/0003-066X.52.4.366","article-title":"On the incomplete architecture of human ontogeny: Selection, optimization, and compensation as foundation of developmental theory","volume":"52","author":"PB Baltes","year":"1997","journal-title":"Am Psychol"},{"key":"pone.0286115.ref002","doi-asserted-by":"crossref","first-page":"512","DOI":"10.1017\/9781316677018.029","volume-title":"The Cambridge handbook of successful aging","author":"M Caprara","year":"2019"},{"issue":"4","key":"pone.0286115.ref003","doi-asserted-by":"crossref","first-page":"540","DOI":"10.1037\/amp0000612","article-title":"The positive plasticity of adult development: Potential for the 21st century","volume":"75","author":"UM Staudinger","year":"2020","journal-title":"Am Psychol"},{"key":"pone.0286115.ref004","doi-asserted-by":"crossref","first-page":"6","DOI":"10.1017\/9781316677018.002","volume-title":"The Cambridge handbook of successful aging","author":"R.
