The POP is a modularized instrument. Each outcome domain is measured with objective as well as subjective items. Self-report items ask specifically about the effects of peer support on the particular outcome in question. There is a manual describing how to administer the POP, a question-by-question guide, the survey instrument itself, a set of response cards, and a report on the psychometric properties of an earlier draft of the POP. These can be downloaded and printed by clicking on the links below.
