Investigators have used it as the criterion for diagnosis
of behavior disturbance against which to gauge the validity
of both screening instruments27 and psychological interview measures.28 The published Spanish version
of the CBCL used in this study has been found to have good internal consistency and concurrent validity in Spanish - speaking populations.29 The CBCL was chosen as the
standard of comparison to avoid basing the calculation
of PSC validity on a small subset
of the data as done in previous studies using structured interviews as the
standard24,30 - 32 and because the CBCL has been widely used as the criterion
standard in previous PSC research in both middle - class30, 33 - 35 and
low - income minority populations.8
Moreover, nurses are rated by the public as having the highest honesty and ethics
standards of all professionals.48 This gives nurses significant power to engage parents and bring about adaptive
behavior change and probably accounts for their
lower number
of attempted visits in which women were not at home compared with paraprofessionals.26
