The present study aimed to validate the psychometric properties of the Practice Environment Scale of Nursing Work Index (PES-NWI) in primary health care (PHC) and to evaluate its construct validity through exploratory and confirmatory factor analyses in a sample of Portuguese nurses. A quantitative, cross-sectional, and validation study design was implemented. Methods: The sample consisted of 1059 nurses from the PHC units of all 55 health center groups (HCGs) in mainland Portugal, 15 health centers in the Autonomous Region of Madeira, and 6 health centers in the Autonomous Region of the Azores. The study tested different structural models using exploratory and confirmatory factor analysis techniques. The reliability of the scale was tested by determining Cronbach\u2019s alpha coefficient. Results: The internal consistency of the PES-NWI was 0.91. Exploratory and confirmatory factor analyses were performed on the PES-NWI model in PHC with five factors: NPOA, NFQC, NMALSN, SRA, and CNPR. The results show that the scale presents acceptable fit quality indexes in the final factorial solution and adequate convergent validity. Conclusion: The PES-NWI in PHC has an adequate, robust, and reliable five-factor structure. The scale is valid and can be used in clinical practice, nursing management, and PHC research.<\/jats:p>","DOI":"10.3390\/ijerph18126422","type":"journal-article","created":{"date-parts":[[2021,6,14]],"date-time":"2021-06-14T10:30:25Z","timestamp":1623666625000},"page":"6422","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Validation of the Psychometric Properties of the Practice Environment Scale of Nursing Work Index in Primary Health Care in Portugal"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2560-7306","authenticated-orcid":false,"given":"Pedro","family":"Lucas","sequence":"first","affiliation":[{"name":"Center for Interdisciplinary Research in Health, Instituto Ci\u00eancias da Sa\u00fade, Universidade Cat\u00f3lica Portuguesa, Rua de Diogo Botelho, 1327, 4169-005 Porto, Portugal"},{"name":"Nursing Research, Innovation and Development Center of Lisbon, Nursing School of Lisbon, 1600-190 Lisbon, Portugal"}]},{"given":"Elvio","family":"Jesus","sequence":"additional","affiliation":[{"name":"Center for Interdisciplinary Research in Health, Instituto Ci\u00eancias da Sa\u00fade, Universidade Cat\u00f3lica Portuguesa, Rua de Diogo Botelho, 1327, 4169-005 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1874-0432","authenticated-orcid":false,"given":"Sofia","family":"Almeida","sequence":"additional","affiliation":[{"name":"Center for Interdisciplinary Research in Health, Instituto Ci\u00eancias da Sa\u00fade, Universidade Cat\u00f3lica Portuguesa, Rua de Diogo Botelho, 1327, 4169-005 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0266-2449","authenticated-orcid":false,"given":"Beatriz","family":"Ara\u00fajo","sequence":"additional","affiliation":[{"name":"Center for Interdisciplinary Research in Health, Instituto Ci\u00eancias da Sa\u00fade, Universidade Cat\u00f3lica Portuguesa, Rua de Diogo Botelho, 1327, 4169-005 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e20190479","DOI":"10.1590\/0034-7167-2019-0479","article-title":"Nursing practice environment in Primary Health Care: A scoping review","volume":"73","author":"Lucas","year":"2020","journal-title":"Rev.
