This study aimed to develop and psychometrically validate an instrument to identify the workload of nurses working in the Psychosocial Care Center - CAPS II. This is methodological development research with a quantitative approach that used the Psychometric Theory of Data, developed in three stages: Stage 1: we carried out the construction of the Nurse's Workload Instrument - CTENF through an Integrative Literature Review and according to the theoretical bases of Christophe Dejours, Edith Seligmann Silva, Laurell and Noriega, and Joyce Travelbee. CTENF was synthesized in six important domains: Domain 1: Organization and Working Conditions, Domain 2: Nurse and Patient Relationship in Mental Suffering, Domain 3: Nurse and Multidisciplinary Team Relationship, Domain 4: Nurse Relationship and Service Management, Domain 5: Mental Repercussions and Domain 6: Physical Repercussions with 75 items. Stage 2: Ten expert judges identified in the Lattes Platform performed the Content Validity based on the criteria proposed by Benner, Tanner, and Chesla. The judges assessed the item / domain relationship at this stage and their agreement was assessed using Kappa, thus obtaining: in domains 1, 2, 3, 4, 5 and 6 concordances above (0.80) in all items among the evaluators, in addition, the general Kappa by domains was calculated: (0.84; 0.92; 0.80; 0.80; 0.98 and 0.84) and the CTENF general Kappa of 0.86. The expert judges and students enrolled in the Nursing Course at the Federal University of Rio Grande do Norte-UFRN Campus Natal-RN also carried out the CTENF Face Validity, with a General Kappa value of 1 in this validity. Stage 3: The Construct Validity was carried out with 300 nurses who work at the Psychosocial Care Centers II in the Northeast Region. In this phase of the research, the data were analyzed using the Item Response Theory (IRT) to assess the latent traits of professionals working in the Psychosocial Care Center - CAPS II. For this, the Gradual Response Model (MRG) was applied, in which the Likert scale was fixed between 1 and 5, representing satisfaction, adequacy and frequency in relation to the item. According to the results of the TRI, all items had a satisfactory power of discrimination and it was possible to identify the items of greatest importance to differentiate professionals with different levels of the latent trait studied. Confirmatory Factor Analysis (AFC) of the psychometric structure of the instrument scale (CTENF) was also performed. In addition, the quality of the fit in the model was verified using the parameters χ2 / G.L., CFI, TLI, GFI and RMSEA, indicating a good or reasonable adjustment of the fixed structure. This study obtained a favorable opinion from the Ethics Committee of the Federal University of Rio Grande do Norte - UFRN under opinion nº. 3.640.801/2019.
