How insomnia, depression, types of anxiety, and sleep patterns relate independently during adolescence

In a study of 318 South Australian high school students, insomnia was found to independently predict depression and panic disorder.

• Insomnia is associated with an increased likelihood of experiencing depression and panic disorder.
• Depression and generalized anxiety disorder are linked to a higher risk of developing insomnia.
• Obsessive-compulsive disorder, separation anxiety, and social phobia do not show a significant relationship with insomnia.
• Eveningness, or a preference for later sleep, is linked to both insomnia and depression, as well as panic disorder.
• Chronotype is identified as a risk factor for insomnia and depression but does not predict specific anxiety subtypes.
