An Active School Transport Instrument to Measure Parental Intentions: The Case of Indonesia

Abstract

An active school transport (AST) instrument to measure parental intentions in a developing country context with 11 latent constructs and 108 measuring items has been created as part of an integrated framework, including psychological and social cognitive constructs, perceived environmental constructs, and habit constructs. The purpose of the current study is to develop and carry out the initial validation of these construct items for measuring parental intentions to promote AST in the context of a developing country. Three experts assigned a content validity index (CVI) to the measurement items and evaluated them based on the item-CVI (I-CVI) and the scale-level-CVI (S-CVI). A pilot study was conducted to test the validity and reliability of the construct items in Palembang, Indonesia, with 34 parents of school-aged children returning the instruments to be analyzed using SPSS Version 23. It was discovered that 93 items were legitimate, since their R values were greater than 0.3, and it was determined that 11 constructs were reliable because the measured items revealed a Cronbach’s alpha coefficient range of 0.8–0.9 (very good) to >0.9. (excellent). This instrument met the requirements for good validity and reliability and thus, can contribute as a novel instrument to measure parental intentions towards AST, especially in developing countries in Asia, particularly Indonesia.
