Background and Development:
The idea for the research was suggested by economic research into public trust. In the study,a phased design was used to overcome the operationalization problem. In the first phase, a qualitative study was conducted; and,in the second,a quantitative study. In the first phase,more than 100 people were interviewed to gain insight into the issues they associated with trust. Eight categories of issues that were derived from the interviews were assumed to be possible dimensions of trust. On the basis of these eight categories and the interviews,a questionnaire was developed that was used in the second phase. In this phase,the questionnaire was sent to 1500 members of a consumer panel; the response was 70 percent. The analysis reveals that six of the eight possible dimensions appear in factor analysis. These dimensions are trust in: the patient-focus of health care providers; macro policies level will have no consequences for patients; expertise of health care providers; quality of care; information supply and communication by care providers; and the quality of cooperation.
The reliability of most scales is higher than 0.8. The validity of the dimensions is assessed by determining the correlation between the scales on the one hand,and people’s experience and a general mark they would assign on the other.

This instrument has not been tested with elderly populations.
Assessment in Minority Populations:

The PTHC has been used to compare public trust in Germany, The Netherlands, England, and Wales (Schee et al. 2007). It has been used in an attempt to measure the overall performance of The Netherlands' health care system over time (Schee et al. 2007b). The PTHC has been translated into Dutch (Hendriks et al. 2007).
There is no cost associated with using this instrument. A copy of the PTHC is available from the author:
