Correlations in bold were expected to be strong (≥0.7 or ≤−0.7), correlations in italic were expected to be moderate (±0.5–0.7). Other correlations were expected not to be strong (≤0.6 or ≥−0.6).

^aSF-12 PCS includes the domains physical functioning, role-physical, bodily pain, and general health; SF-12 MCS includes the domains vitality, social functioning, role-emotional, and mental health.

^bDSI sleep problems were defined as trouble falling asleep and/or trouble staying asleep.
