Abstract
Background: Aggression is one of the symptoms of bipolar disorder.
This expression can be associated with negative personal and social effects.
Objective: This study aimed to determine the effect of anger management education
on aggression in bipolar disorder.
Methods: This semi-experimental study with a repeated measures design was
conducted in Hamadan, Iran, 2018. Fifty-two bipolar type-1 disorder patients
were randomly selected from the Psychiatric Ward of Farshian Hospital through
the convenience sampling method. The anger management education intervention
included four sessions. Also, the State-Trait Anger Expression Inventory-2
(STAXI-2) was completed by the subjects before, immediately, and two weeks
after the educational intervention. Data analysis was performed in SPSS16, using
Mauchly’s sphericity test and the least significant difference.
Results: The mean aggression score was 61.38±11.59 before the intervention,
which reduced to 27.18±8.61 and 18.86±6.45 immediately and two weeks after
the intervention, respectively. The repeated measures test showed that the decreasing
trend of scores was statistically significant (P<0.001). Moreover, pairwise
comparison of study stages demonstrated a significant difference between
the first and second stages (P<0.001) and the second and third stages (P<0.001).
Conclusion: Anger management education reduced the level of aggression in
bipolar type-1 disorder. Therefore, it can be incorporated into nursing care programs.
