Comments were used to make inferences about the students' problem-solving behaviors…

Empirical research supporting the contention that insecure attachment is related to internalizing behaviors has been inconsistent. Across 60 studies including 5,236 families, we found a significant, small to medium effect size linking insecure attachment and internalizing behavior (observed d = 0.37, 95% CI [0.27, 0.46]; adjusted d = 0.19, 95% CI…
