Objetivo: Determinar la relación entre procrastinación académica y ansiedad en estudiantes detercero, cuarto y quinto año del nivel de secundaria. Metodología: De enfoque cuantitativo, diseñono experimental, de corte transversal y de alcance correlacional, ya que no se manipularon lasvariables, se midió en un momento determinado y se busca determinar si existe relación entre laprocrastinación académica y ansiedad ante los exámenes. Los instrumentos utilizados fueron Escalade Procrastinación Académica (EPA) y el Inventario de autoevaluación de la Ansiedad ante Exámenes(IDASE). La muestra estuvo conformada por 280 estudiantes de dos colegios Adventistas de Lima, queoscilan entre las edades de 14 y 17 años de ambos sexos. Resultados: Existe relación significativaentre la procrastinación académica y ansiedad frente a los exámenes (rho= 0.118, p=0.05), asícomo en su dimensión de postergación de actividades y ansiedad ante los exámenes (rho=0.152*,p=0.011). Finalmente, se encontró que la dimensión de autorregulación académica no se relacionacon la ansiedad ante los exámenes (rho=0.091, p=0.131). Conclusión: Por lo tanto, existe relaciónsignificativa entre la procrastinación académica y ansiedad frente a los exámenes en los estudiantesdel nivel secundario.

Teacher care in the university setting is crucial for the academic, emotional, and social development of students, encompassing moral virtues such as compassion and professional competence. The students’ perception of teacher care directly relates to their well-being and active participation in learning. Despite the recognized importance of teacher care, there is a lack of adequate instruments to measure it, especially in specific cultural and educational contexts like Peru. The aim of this research is to develop and assess the psychometric properties of a scale measuring student perception of teacher care in the Peruvian university context, to provide a valid and reliable tool for future research and educational practices. An instrumental study was conducted with 910 university students aged between 18 and 50 years (M = 20.2, SD = 3.45). The Student Perception of Teacher Care Scale (SPTCS) was used, divided into five dimensions (Compassion, Competence, Confidentiality, Trust, and Awareness). Exploratory (EFA) and confirmatory (CFA) factor analyses were conducted to evaluate the scale’s internal structure, along with reliability analyses and measurement invariance across genders. The EFA identified a four-factor structure reflecting the dimensions of Confidentiality and Trust, Competence, Awareness, and Compassion. The CFA confirmed this structure with good fit indices for four-factor models, which was then adjusted to a five-factor model, one of which is a second-order factor (χ² = 720.727, df = 369, CFI = 0.951, TLI = 0.946, RMSEA = 0.046, and SRMR = 0.032). Internal reliability was high (α and ω > 0.9 for all factors). Measurement invariance was established across genders, allowing for valid comparisons between men and women. It is concluded that the Student Perception of Teacher Care Scale proves to be a valid and reliable instrument for measuring teacher care in the Peruvian university context. The results emphasize the multidimensionality of teacher care and its significance for the educational environment and student experience. This study contributes to educational research and teaching practice, offering a means to assess and improve caring relationships in higher education.

The aim of this study was to assess the factorial structure of the scale, the method's effect associated with its negative items, its temporal invariance, and factorial invariance according to sex. For this purpose, three samples were collected, an initial sample of 200 participants, a second sample of 461 participants and a third sample of 107 participants; making a total of 768 Peruvian university students. Other instruments were applied together with the EROS scale in order to measure satisfaction with life, anxiety, stress and depression. Regarding the results, in the initial sample it was found that the original scale containing positive and negative items does adequately fit the data (RMSEA = .19; CFI = .77; TLI = .71) and also evidence was found supporting the existence of a methodological effect associated with the negative items. It was also found that version B of the scale which only has positive items data fits the data (RMSEA = .13; CFI = .96; TLI = .95). In the second sample it was found that version B still had a good fit to the data in a larger sample (RMSEA = .07; CFI = .98; TLI = .98). In addition, it was found that the scale can be considered invariant according to sex and presents validity based on other constructs. In the third sample it was found that the test-retest reliability of the scale was adequate (.70 [CI95% .593–.788]) and also evidence was found in favor of the temporal invariance of the scale. It is concluded that the scale formed only by positive items presents more robust psychometric properties and constitutes a better alternative to measure the level of reward provided by the environment.
