Parents?? Perception of Uncertainty Concerning Their Hospitalized Child

The Parent Perception of Uncertainty Scale (PPUS) was developed to measure a perceptual variable believed to influence parents' response to their child's illness and hospitalization. This 31-item Likert-format scale was modified from the original form of the uncertainty scale. The PPUS was composed of four factors measuring the four dimensions of uncertainty consistent with theoretical predictions. Initial testing for reliability found the coefficient alphas and thetas to be adequate for a new scale. Validity testing with theoretically relevant external variables was partially supportive of predictions. Questions remain concerning the adequacy of Factor II. Further testing of the scale is indicated.
