Hypothesis
Are elevated depression screening scores in older adults due to sleep disorders rather than depression itself?
Conclusion
Sleep disorders and depressive symptoms are associated, but the PHQ-9 is still an adequate screening tool for depression in older adults with sleep disorders.
Supporting Evidence
- The study included 2,257 older adults who screened positive for depression.
- The MIMIC analysis showed a positive association between sleep disorders and depression.
- The model fit was good with RMSEA=0.040 and CFI=0.99.
Takeaway
This study looked at older people to see if their depression scores were really about sleep problems instead. It found that while sleep issues and depression are linked, the depression test still works well.
Methodology
A multiple indicator multiple cause (MIMIC) analysis was used to examine the relationship between sleep disorders and depression in older adults.
Participant Demographics
Adults aged 65 and older with at least two outpatient primary care visits.
