Objecti.e: The purpose of thi. study was to test whi.h stressors worsen the sym.tom. percei.ed by pati.nts wi.h lupus, thus broadeni.g and corroborati.g results obtai.ed i. a previ.us study publi.hed i. Psychosom.ti. m.di.i.e. m.thods: i. order to exam.ne thi. questi.n, we selected 43 pati.nts wi.h lupus whose sym.-tom. worsened due to the effects of dai.y stress. These pati.nts were di.i.ed i.to two groups: pati.nts whose i.crease i. cli.i.al lupus sym.-tom.tology was predi.ted by an i.crease i. dai.y stressors on the sam. day (G1) and pa-ti.nts whose i.crease i. cli.i.al lupus sym.-tom.tology was predi.ted by an i.crease i. dai.y stressors the day before and the sam. day (G2). Later, three factori.l analyses were con-ducted wi.h the i.em. related to stressors and the i.em. related to lupi. sym.tom.. Results: The results showed that i. G1 there were three factors that m.de up a total of 35.08% of the explai.ed vari.nce. The stressors associ.ted wi.h certai. sym.tom. of the i.lness i. thi. group are feeli.g i.l or bei.g worri.d about thei. physi.al appearance, wi.h the m.i. stressor bei.g the i.lness i.self. However, i. G2, two factors were found that m.de up a total of 40.37% of the explai.ed vari.nce for lag=0 and 38.67% for lag=1. The stressors associ.ted wi.h the m.jori.y of the lupus sym.tom. are of an i.terpersonal and work-related nature. Thi. as-soci.ti.n was m.i.tai.ed when we carri.d out the factori.l analyses wi.h the i.em. of the sym.tom. from.the followi.g day. Conclusi.ns: The i.terpersonal and work-related stressors are related to a worseni.g i. the m.jori.y of the lupi. sym.tom. i. the pati.nts whose sym.to-m.tology worsens as a result of dai.y stress experi.nced the day before.
