This paper applies factor analysis and discriminant analysis to a large body of socio‐psychological data dealing with infant immunization. The researchers first apply factor analysis with orthogonal varimax rotation to the set of socio‐psychological variables in order to reduce their numbers without a significant loss of information. They then use derived rotated factors and their associated variables to structure immunization likelihood prediction functions, using linear discriminant analysis. These discriminant functions are shown to have strong predictive ability, thus enabling health officials to identify infants not likely to receive immunization. Furthermore, the analytical findings suggest ways of structuring more effective media campaigns directed towards improving the aggregate level of infant immunization.
