This study aimed at using the General Graded Unfolding
Model for constructing an attitude scale toward family planning. To
achieve the purpose of the study a preliminary Likert rating scale of
50 items was constructed.The scale was administrated to a randomly
selected sample of 1200 parents. The results indicated 41 items met
the expectations of the model and their scale value cover the latent
continuum and they have suitable psychometric properties with a
reliability coefficient 0.93,and they also have several validity
indicators. The results also showed that the items of the scale have
high discrimination. This made them contribute in offering the
maximum amount of the information within the range of items vale
scale. So,they consist with the model expectations
