We tested the psychometric properties of an instrument entitled intention to use oral contraceptive tool (IUOCT). This instrument was developed to evaluate Jordanian Muslim women's intention to use oral contraceptives (OCs). We used the theory of planned behavior (TPB) as a conceptual framework for developing the IUOCT. The internal consistency of the IUOCT ranged from .70 to .94. The stability of IUOCT ranged from.79 to.85. Factor analysis identified four factors that represented the three constructs of the TPB. The known-group technique showed significant difference between past users and nonpast users of OCs. The predictive validity analysis showed that each scale contributed to the variability in the intention.
