Parent reading beliefs are the ideas that parents have concerning the influence of reading and their own efficacy as language teachers to their children. In the intervention More Languages, More Opportunities, one of the goals is to positively influence the parental reading beliefs. The participants were 16 mother-child couples from bilingual Netherlands Antillean families in the Netherlands. They completed the Dutch adaptation of the Parent Reading Belief Inventory (PRBI) [DeBaryshe, B.D., & Binder, J.C. (1994). Development of an instrument for measuring parental beliefs about reading aloud to young children. "Perceptual and Motor Skills," 78(3c), 1303-1311.]. Ten mothers completed the inventory for a second time. Antillean mothers are on average positive about their own role in the language development of the child. The results of the composed "contrast group" did not contrast as strongly as was expected, although two of the seven subscales did show differences. When looking at both administration moments of the PRBI of Antillean mothers, the conclusion can be drawn that reading beliefs are not necessarily a stable construct.
