To date, there is little research and a lack of instruments available to address and assess positive mental health literacy levels in community-dwelling adults. Thus, this study sought to develop an instrument to assess positive mental health literacy in adults and to evaluate its psychometric properties. A scale developed in European Portuguese and composed of 32 items was designed to assess positive mental health literacy among community-dwelling adults and was validated using exploratory factor analysis. Five latent factors were identified (decision making, prosocial attitudes, perception of resources, community involvement, and problem solving), whose hypothesised structure was confirmed by confirmatory factor analysis using structural equation modelling. Evidence showed that the scale\u2019s factor structure is reliable and valid and adequately represents the theorised constructs. Thus, this may be a useful assessment tool for clinical practice since it will allow a more rigorous assessment of positive mental health literacy and better mental health promotion interventions in the population.<\/jats:p>","DOI":"10.3390\/ijerph20146391","type":"journal-article","created":{"date-parts":[[2023,7,19]],"date-time":"2023-07-19T01:02:23Z","timestamp":1689728543000},"page":"6391","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Construction and Validation of the Positive Mental Health Literacy Assessment Scale in Adults"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8103-7221","authenticated-orcid":false,"given":"Cl\u00e1udia","family":"Chaves","sequence":"first","affiliation":[{"name":"Superior School of Health, Polytechnic of Viseu, Rua Dom Jo\u00e3o Cris\u00f3stomo Gomes de Almeida, 102, 3500-843 Viseu, Portugal"}]},{"given":"Jo\u00e3o","family":"Duarte","sequence":"additional","affiliation":[{"name":"Superior School of Health, Polytechnic of Viseu, Rua Dom Jo\u00e3o Cris\u00f3stomo Gomes de Almeida, 102, 3500-843 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9245-256X","authenticated-orcid":false,"given":"Francisco","family":"Sampaio","sequence":"additional","affiliation":[{"name":"Nursing School of Porto, Rua Dr. Ant\u00f3nio Bernardino de Almeida, 830, 844, 856, 4200-072 Porto, Portugal"},{"name":"CINTESIS@RISE, Nursing School of Porto (ESEP), Rua Dr. Pl\u00e1cido da Costa, 4200-450 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7608-3506","authenticated-orcid":false,"given":"Joana","family":"Coelho","sequence":"additional","affiliation":[{"name":"CINTESIS@RISE, Nursing School of Porto (ESEP), Rua Dr. Pl\u00e1cido da Costa, 4200-450 Porto, Portugal"},{"name":"Northern School of Health of the Portuguese Red Cross, Rua da Cruz Vermelha Cidacos-Apartado 1002, 3720-126 Oliveira de Azem\u00e9is, Portugal"}]},{"given":"Amadeu","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Superior School of Health, Polytechnic of Viseu, Rua Dom Jo\u00e3o Cris\u00f3stomo Gomes de Almeida, 102, 3500-843 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3953-6123","authenticated-orcid":false,"given":"Vanda","family":"Santos","sequence":"additional","affiliation":[{"name":"Research Centre on Didactics and Technology in the Education of Trainers (CIDTFF), University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Centre for Informatics and Systems of the University of Coimbra (CISUC), University of Coimbra, 3030-790 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5620-3478","authenticated-orcid":false,"given":"Carlos","family":"Sequeira","sequence":"additional","affiliation":[{"name":"Nursing School of Porto, Rua Dr. Ant\u00f3nio Bernardino de Almeida, 830, 844, 856, 4200-072 Porto, Portugal"},{"name":"CINTESIS@RISE, Nursing School of Porto (ESEP), Rua Dr. Pl\u00e1cido da Costa, 4200-450 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,18]]},"reference":[{"key":"ref_1","unstructured":"Wei, Y.
