Evaluar las caracter\u00edsticas psicom\u00e9tricas de la escala de Depresi\u00f3n, Ansiedad y Estr\u00e9s (DASS-21) en universitarios de Lima, Per\u00fa. Materiales y m\u00e9todos. Se\u00a0 realiz\u00f3 un estudio instrumental en 1163 estudiantes de una universidad estatal, donde se evalu\u00f3 la validez y\u00a0 confiabilidad de la DASS-21, en concordancia con los\u00a0 est\u00e1ndares internacionales. Resultados. Se efectu\u00f3 el\u00a0 an\u00e1lisis factorial confirmatorio con un primer modelo de tres factores (x2=706,5; gl=186; CFI=0,986; TLI=0,985;\u00a0 RMSEA=0,049; SRMR=0,057) y otro de segundo orden\u00a0 (x2=706,5; gl=186; CFI=0,986; TLI=0,985; RMSEA=0,049;\u00a0 SRMR=0,057), en el cual se report\u00f3 medidas de ajuste\u00a0 esperados. Adem\u00e1s, se estableci\u00f3 asociaciones con otras medidas, salud mental positiva (r&gt;-0,49) cuyos resultados fueron correlaciones inversas y valoraciones\u00a0 moderadas, estad\u00edsticamente significativas. Tambi\u00e9n, se\u00a0 calcul\u00f3 las medidas de la invarianza m\u00e9trica en funci\u00f3n\u00a0 al sexo. Los coeficientes de confiabilidad, omega, alfa\u00a0 ordinal y Gutman alcanzaron valores mayores a 0,90\u00a0 seg\u00fan lo esperado. Conclusiones. La DASS-21 evidenci\u00f3\u00a0 validez del an\u00e1lisis de la estructura interna, validez de\u00a0 criterio concurrente, discriminante y fiabilidad por\u00a0 consistencia interna como tambi\u00e9n es invariante en\u00a0 funci\u00f3n a hombres y mujeres.<\/jats:p>","DOI":"10.17843\/rpmesp.2025.423.14209","type":"journal-article","created":{"date-parts":[[2025,10,9]],"date-time":"2025-10-09T19:12:40Z","timestamp":1760037160000},"page":"291-9","source":"Crossref","is-referenced-by-count":4,"title":["Evaluaci\u00f3n psicom\u00e9trica de la escala de Ansiedad, Depresi\u00f3n y Estr\u00e9s (DASS-21) en estudiantes universitarios peruanos","Psychometric evaluation of the Depression, Anxiety and Stress Scale (DASS-21) in peruvian university students"],"prefix":"10.17843","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7677-5425","authenticated-orcid":false,"given":"Ingrid","family":"Cirilo-Acero","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0680-2616","authenticated-orcid":false,"given":"Marivel","family":"Aguirre-Morales","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3373-3334","authenticated-orcid":false,"given":"Josu\u00e9 Michael","family":"Franco-Mendoza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7439-5699","authenticated-orcid":false,"given":"Lizley Janne","family":"Tantalean-Terrones","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2226-3349","authenticated-orcid":false,"given":"\u00b4Jos\u00e9","family":"Livia-Segovia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7920","published-online":{"date-parts":[[2025,9,30]]},"container-title":["Revista Peruana de Medicina Experimental y Salud P\u00fablica"],"original-title":[],"link":[{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/14209\/6011","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/14209\/6024","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/14209\/6011","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,9]],"date-time":"2025-10-09T19:12:43Z","timestamp":1760037163000},"score":1,"resource":{"primary":{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/view\/14209"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,9,30]]},"references-count":0,"URL":"https:\/\/doi.org\/10.17843\/rpmesp.2025.423.14209","relation":{},"ISSN":["1726-4642","1726-4634"],"issn-type":[{"value":"1726-4642","type":"electronic"},{"value":"1726-4634","type":"print"}],"subject":[],"published":{"date-parts":[[2025,9,30]]}}}
