Examination of Adherence Self-Efficacy and Outcome Expectancy Regarding Antiretroviral Treatment According to HAART Medication Adherence

	Adherence
Self-efficacy and outcome expectancy	Adherent	Nonadherent	p value
Self-efficacy (SE):
Mean (SD)	85.1 (14.3)	61.4 (23.1)	< 0.0001
Median	89.0	67.5	< 0.0001
Outcome expectancy (OE):
Mean (SD)	29.5 (4.3)	26.4 (5.0)	< 0.0001
Median	31.0	27.0	< 0.0001

Cronbach α: Self-efficacy (SE): Cronbach α is equal to 0.91; the value of Cronbach α obtained with the deletion of a single variable from the scale ranged from 0.90 to 0.92.

Outcome expectancy (OE): Cronbach α is equal to 0.62; the value of Cronbach α obtained with the deletion of a single variable from the scale ranged from 0.52 to 0.66.

HAART, highly active antiretroviral therapy; SD, standard deviation.
