The Parent Trust Scales
Thus, vulnerability, benevolence, reliability, competence, honesty, and openness characterize the measures of parent trust. There are two parent trust scales: Parent Trust in School (PTS-Scale) and Parent Trust in Principal (PTP-Scale), which were developed by Patrick Forsyth (email@example.com) of The University of Oklahoma and Curt Adams (Curt.Adamsfirstname.lastname@example.org).
Parent Trust in School-(PTS-Scale)
The STS-Scale is a 10-item Likert questionnaire that measures parents' trust in the school. The scale is administered to parents to describe their trust in their children?s school and scored along an eight-point scale from 1(strongly disagree) to 8 (strongly agree); the higher the score, the greater the trust in the school.
Parent Trust in Principal-(PTP-Scale)
The STP-Scale is a 15-item Likert questionnaire that measures parents' trust in the principal. The scale is administered to parents to describe their trust in the principal and scored along an 8-point scale from 1(strongly disagree) to 8 (strongly agree); the higher the score, the greater the trust in the principal.
Reliability and Validity of the Parent Trust Scales
Reliability, as measured by Cronbach's alpha, was .95 for both the PTS-Scale and the PTP-Scale, suggesting strong internal consistency among the items for both scales. The structure of the factor analysis supported the construct validity of both scales (Forsyth, Adams, & Hoy, in press).
All items are scored from 1 to 8 and then summed for the total score for each parent. Then the parent scores are averaged for each school.
