Interaction between anxiety and depression on suicidal ideation, quality of life, and work productivity impairment: Results from a representative sample of the Lebanese population

To assess the association between the interaction of anxiety and depression on the suicidal ideation, quality of life (QOL), and work productivity/impairment in Lebanon.Cross-sectional.1487 participants were enrolled between November 2017 and March 2018.The interaction of anxiety and depression (β = .101), higher depression alone (β = .021), higher anxiety traits (STAI-B) (β = .007) were associated with higher suicidal ideation. Higher depression (β = 1.177), having more anxiety traits (STAI-B) (β = .485) and higher anxiety (STAI-A) (β = .298) were associated with higher activity impairment. Higher depression, higher anxiety traits and state, were associated with lower mental and physical QOL.Screening for anxiety and depression can help clinicians improve patients' QOL and work productivity and decrease the suicidal ideation risk.
