RT Article T1 The Development and Validation of the Practicing Faith Survey JF Journal of psychology and theology VO 51 IS 1 SP 67 OP 86 A1 Cheng, Albert A1 Green, Beth A1 Smith, David A. 1967- LA English PB Sage Publishing YR 2023 UL https://www.ixtheo.de/Record/1835663036 AB We introduce a new instrument, called the Practicing Faith Survey (PFS), to assess faith formation among students in K-12 Christian schools. We begin by describing the conceptual and theological background of the PFS, underscoring the ways it differs from existing instruments of faith formation because of its particular focus on Christian practice within the context of learning and the vocation of the student. We then describe the procedures behind developing the PFS and its five domains: Intellectual, Relational, Introspective, Beneficent, and Formational Practices. We then provide evidence of validity and reliability based on a pilot study that involved 1,200 US and Australian Christian school students in fifth through 12th grades. We conclude with recommendations about how Christian school educators, students, and parents can use the PFS in practice.
