Background: To report an open trial of divalproex sodium in 10 adolesc
ents with chronic temper outbursts and mood lability. Method: Ten adol
escents meeting screening criteria for chronic temper outbursts and mo
od lability were followed for 5 consecutive weeks on open divalproex s
odium treatment. Temper outburst frequency and mood swings severity at
pretreatment and posttreatment were compared by using paired t tests.
Subjects continued to be followed to judge persistence of response. R
esults: All subjects showed clear improvement at 5 weeks and maintaine
d it during followup while taking medication. Rapid relapse and recove
ry occurred in 5 of 6 patients who discontinued and then resumed medic
ation. Conclusion: Divalproex sodium may be helpful in teenagers who h
