marginally non-significantp = .071
For social loneliness, the interaction was marginally non-significant (F(4, 3975) = 2.16, p = .071), but post hoc comparisons revealed a clear gradient: All pairwise limitation comparisons were significant in the middle-aged group ( p s < 0.007), two of three were significant in the 66–79 group, and none reached significance in the 80 + group.
