When using formative constructs, should all the items be measured on the same scale or is it OK to mix item types?
For example, say Performance was measured as:
1. I am very satisfied with performance (measured on a 7 point Likert scale)
2.. The time I spend productively per day is ___ hours
3. The percent of products delivered on time is __percent
In this example, each item is measured on a different scale. Is it technically OK to use PLS to combine these as formative indicators of performance? Or should we use items that are measured on the same scale?
Thank you for your insights.
Best regards,
