Although, in the last 20 years, several interventions have been developed to reduce the impact of social isolation and loneliness on the health of older people. However, only a small proportion of these interventions are effective. This study aims to describe the components of the Psychological Support Service for Socially Isolated Elderly People (PSIE), in addition to analysing the effectiveness of a community intervention based on an outreach strategy to combat situations of social isolation in the elderly population. The sample consisted of 63 people over 65 years of age from the city of Madrid (Spain), detected by the socio-health services as people at risk of social isolation. Sociodemographic, mental health, health and psychosocial functioning, global functioning, disability and socio-sanitary needs were evaluated with observational scales. Descriptive statistics were calculated for sociodemographic and mental health variables. An analysis was carried out to study the possible influence of gender in the initial sample on the different variables assessed, using Chi-squared and Student\u2019s t-tests for independent samples, with measures of effect size in each case. A study of the effectiveness of PSIE was carried out with an analysis of pre- and post-treatment measures. A Student\u2019s t-test was used for related samples, as well as the effect size of Cohen\u2019s d statistic. For the assessment of the possible influence of gender on the results of the intervention, a 2 \u00d7 2 repeated-measures ANOVA (pre-\/post-measures \u00d7 gender) was conducted. Regarding mental health, 65.2% of the sample presented symptoms compatible with a severe mental disorder, the most frequent being psychotic disorder (22.7%), alcohol use disorder (16.7%), personality disorder (15.2%), anxiety disorders (10.4%) and mood disorders (10.4%). The gender variable does not seem to have an influence on any of the outcome measures studied. The results of the effectiveness study indicate that the PSIE is an intervention programme that serves to improve the scores of people in the sample in all variables that the programme studied. Some of the components of PSIE that could explain its effectiveness are individualized interventions, with a home-based approach by professionals, serving as a link between the older person and the normalized social-sanitary network. Further research is required to provide more robust data on the effectiveness of interventions.<\/jats:p>","DOI":"10.3390\/ijerph19052665","type":"journal-article","created":{"date-parts":[[2022,2,25]],"date-time":"2022-02-25T10:00:40Z","timestamp":1645783240000},"page":"2665","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["People over 65 Years Old in Social Isolation: Description of an Effective Community Intervention in the City of Madrid (Spain)"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6046-163X","authenticated-orcid":false,"given":"Ana","family":"Santos-Olmo","sequence":"first","affiliation":[{"name":"School of Psychology, Personality, Evaluation and Clinical Psychology Department, Complutense University of Madrid, Campus de Somosaguas, Ctra. de H\u00famera, s\/n, Pozuelo de Alarc\u00f3n, 28223 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9497-0275","authenticated-orcid":false,"given":"Berta","family":"Aus\u00edn","sequence":"additional","affiliation":[{"name":"School of Psychology, Personality, Evaluation and Clinical Psychology Department, Complutense University of Madrid, Campus de Somosaguas, Ctra. de H\u00famera, s\/n, Pozuelo de Alarc\u00f3n, 28223 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel","family":"Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"School of Psychology, Personality, Evaluation and Clinical Psychology Department, Complutense University of Madrid, Campus de Somosaguas, Ctra. de H\u00famera, s\/n, Pozuelo de Alarc\u00f3n, 28223 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,25]]},"reference":[{"key":"ref_1","unstructured":"Hall, M., and Havens, B.
