Best-fitting model in italics

M1: daily hassles, perceived uncertainty and adaptive performance fit load onto three separate latent factors

M2: daily hassles and perceived uncertainty were loaded onto one latent factor plus adaptive performance was loaded onto one separate latent factor

M3: all the variables (daily hassles, perceived uncertainty and adaptive performance) were loaded onto one single factor
