The same assessment may be run multiple times for the same person and in some cases it is appropriate to merge the factor results produced. For example, a CSN assessment may be run for client 1 focusing on client 2. It may subsequently be run again for client 1 focusing on client 3. In this case, client 1 is assessed twice for Substance Abuse. The results for substance abuse can be merged i.e. only one result for substance abuse is displayed when an assessment is run, rather than two sets of results. The merge indicator dictates if factor results are merged or not when an assessment is run. If merging is switched on, the results are merged and the latest factor results is displayed.
