If you develop your own coding system for touches, you need to make sure that you do a pilot test to make sure that your raters can reliably identify the behaviors of interest. The pilot test will tell you if you are missing types of touches, if you need to eliminate types that are never seen, if you need to combine categories, etc. Once you have a complete and usable set of codes/behaviors, you are ready to conduct and record your observations. When you are reading an observational study, look for pilot studies or descriptions of how this coding system was used in previous studies. |
