Loadings of first six items from the PIS fall into one single component. The seventh item has been omitted in this case due to the distinct differences in question phrasing. The seventh item incorporated into the PIS-7 reads: ‘I have made positive changes to my lifestyle and/or behaviour in accordance with the insights I have gained as part of my treatment/experience’.
