Purpose:
To examine these temperaments among patients with substance use disorder (SUD) in the Lebanese population.
Design:
Case-control.
Methods:
Fifty-seven controls and 57 patients with SUD were enrolled between April and September 2017.
Results:
A significantly higher mean of depressive, irritable, and anxious temperaments was found in addicted patients as compared with the nonaddicts. However, the results of the multivariate analysis showed that anxious, hyperthymic, irritable temperaments would significantly increase the odds of addiction in participants (ORa = 25.20, 1.057, 1.168, 1.241, and 1.275). Cyclothymic temperament would significantly decrease the odds of addiction in participants (ORa = 0.817). Furthermore, suicidality was associated with depressive, anxious, and irritable temperaments.
Practice Implications:
Hyperthymic, irritable, and anxious temperaments were the main temperaments found in patients with SUD in Lebanon.
