“…8-17) offered very detailed 13 steps for scale development, 'decide what you want to measure, develop the theoretical foundations, generate item pool, write items, decide on number of items, establish content and face validity, decide on scaling/response options, conduct pre-test/pilot study of the scale, collect data, reduce item pool, establish dimensionality and validity, establish reliability, reproduce results'. Although there are a variety of scale development procedures in literature, the ISTUP was developed by considering the eight phases emphasized by Şahin and Boztunç Öztürk (2018): (1) clearly decide what you want to measure and develop the theoretical foundations of related variables, (2) generate item pools, (3) decide the format of the scale, (4) expert review of the items, (5) ensure item validity, (6) administer the scale and conduct confirmatory analysis, (7) evaluate the items and (8) give the final form to the scale. The phases adopted in the present study are described as follows:…”
