You can add additional questions that you might ask a new client (e.g. client contact information, risk warnings/disclaimer statements or other information collected for the purposes of delivering your services). However, the questions and the process of the APSS must be used in their entirety, as they are in the tool, and must be referenced appropriately (Exercise and Sports Science Australia, AUSactive, Sports Medicine Australia and Exercise is Medicine Australia, 2019).
The reason for this is that they are evidence based and have been carefully designed to elicit client responses that will uncover health risks that might contra-indicate exercise and which require further guidance from a medical or allied health professional. Using only part of one of the stages or altering the intended process may prevent accurate risk factor calculation and risk assessment which could lead to unsafe and unsuitable exercise prescription and advice.
