The Patient Satisfaction Questionnaire (PSQ), consisting of 80 items, was originally developed by Ware and his colleagues (Ware, Snyder, and Wright, 1976 a, b; see “Related Reading” below).A more recent version of the questionnaire is the PSQ-III, available below.Items measured demographics and direct and indirect theoretical constructs.
The EP questionnaire test-retest scores for consistency (Cronbach alpha) and stability (ICC) were intention (test: Cronbach alpha=.94; retest: Cronbach alpha=.98; ICC=.89), attitude (.74, .72, .70), subjective norm (.79, .78, .75), perceived behavioral control (.67, .65, .66), attitudinal beliefs (.94, .86, .60), normative beliefs (.83, .87, .79), and control beliefs barriers (.58, .67, .78) and facilitators (.97, .85, .30).
The AHP questionnaire scores for consistency and stability were: intention (test Cronbach alpha=.69, retest Cronbach alpha=.81, ICC=.48), attitude (.85, .87, .83), subjective norm (.47, .82, .62), perceived behavioral control (.55, .62, .60), attitudinal beliefs (.92, .91, .82), normative beliefs (.85, .90, .74), and control beliefs barriers (.58, .55, .66) and facilitators (.72, .94, –.05).
The PSQ sub-scales show acceptable internal consistency reliability.
Furthermore, corresponding PSQ-18 and PSQ-III subscales are substantially correlate with one another.

When the "public good" relates to education or health care, standards of acceptable performance are clearly defined by regulatory and professional bodies and society holds practitioners fully accountable when performance is unacceptable or questionable.
