  1. Statistically significant differences were observed across several predictors and perceived difficulty dimensions. In terms of gender, men reported greater difficulty in home care (Z = 2.091, p = 0.037, η² = 0.022), technology use (Z = 2.188, p = 0.029, η² = 0.024), and leisure activities (Z = 1.988, p = 0.047, η² = 0.020), all with small effect sizes.
