The purpose of this study was to develop and test an instrument to measure parents' trust in nurses. The conceptual framework for the Parental Trust in Nurses Scale (P-TINS) included four dimensions of parental trust--generalized trust, trust in the imagined nurse, trust based on previous experience with nurses, and situation-specific trust, and a closely related construct--perception of risk. Content validity was enhanced by basing the 40 items of the Likert-type, sixth-grade level scale on parents interviews and qualitative studies and by ratings of parent and nurse content experts. The initial version of the P-TINS was administered to 406 parent of hospitalized children. Confirmatory principal axis factor analysis supported a four-factor structure. Congruence between the conceptual framework and the Generalized Trust and Perceived Degree of Risk subscales was clear. The remaining three subscales loaded on two factors which were collapsed into a single factor because they were comprised of conceptually similar questions that differed only in direction of wording. The final version of P-TINS consisted of 25 items in 3 subscales. Standardized alpha was.88 for P-TINS;.83 for the Generalized Trust subscale,.89 for the Specific Trust in Nurses subscale, and.69 for the Perceived Degree of Risk subscale. Construct validity was supported by inverse relationships of the Revised P-TINS scores with other variables. Correlation of P-TINS with parental anxiety was r = $-$.36 ($p < .001$), with parental preference for control was r = $-$.31 ($p < .001$), and with parental uncertainty was r = $-$.50 ($p < .001$). As predicted based on qualitative studies, parents of chronically ill children had lower trust in nurses (t = $-$2.44, p =.02) and parents of previously hospitalized children had lower trust in nurses (t = $-$2.54, p =.01) than parents who did not meet these conditions. These analyses represent beginning support for the reliability and validity of the P-TINS. Potential uses of the P-TINS include evaluation of outcomer of health care changes that may affect trust in nurses, testing interventions aimed at increasing trust, and examination of relationship between parental trust and other variables.
