Development of a drug use resistance self-efficacy (DURSE) scale.
OBJECTIVE
To develop and evaluate psychometric properties of a new instrument, the drug use resistance self-efficacy (DURSE) scale, designed for young adolescents.


METHODS
Scale construction occurred in 3 phases: (1) initial development, (2) pilot testing of preliminary items, and (3) final scale administration among a sample of seventh graders (n=223) to examine psychometric properties.


RESULTS
DURSE items appeared to tap a unique dimension of resistance self-efficacy. Initial psychometric properties of the scale were satisfactory.


CONCLUSIONS
The DURSE scale may offer an opportunity to measure important, as yet untapped, constructs related to adolescents' abilities to refuse substance use in social contexts.
