Research was conducted with a sample of 534 students aged between 13 and 17 years (M = 14.49; SD = 1.805). Exploratory factor analysis was conducted using the FACTOR program and confirmatory factor analysis was conducted using the M-PLUS 7 program. Results indicate that a four-dimensional model is most appropriate for bringing together the emotional and physical dimensions. Further, 11 items were removed due to poor factor loadings. The majority of factors were directly and positively correlated (99%; p < .01). The data obtained supports conclusions that the AF-5 meets validity and reliability requirements for it to be considered a useful instrument for use with young people during the COVID- 19 lockdown period. 2026-01-19T13:05:47Z 2026-01-19T13:05:47Z 2023 journal article Zurita-Ortega, F., Lindell-Postigo, D., González-Valero, G., Puertas-Molero, P., Ortiz-Franco, M., y Muros-Molina, J.J.
