Internal consistency analysis indicated that the three factors have strong reliability with Cronbach alphas ranging from .81 to .92. The test-retest ICC coefficient is .80. The test-retest coefficients for the subscales will power compulsive behavior and negative coping are .76 .51 and .64 respectively. Overall the data show that the CCBQ has acceptable reliability and validity demonstrating that it can be a research instrument for assessing heroin craving beliefs.
