not differ significantly across groups (p = 0.8610), but 0-16 h and 0.5-16 h declines were both less pronounced in high-lonely individuals (p = 0.0260 and 0.0396, respectively). Blunted diurnal cortisol rhythm was also observed in analyses treating measurement occasion as a linear effect of hours post-awakening (slope = -0.202 ± 0.033 μg/dl/h for high-lonely versus -0.301 ± 0.042 for low-lonely; Hour × Loneliness interaction, p = 0.0119).
