Incremental costs associated with social marketing and crowdsourced arms

PhaseFinancial costs Inputs to be capture, can all directly be found in the project financial accounts, main challenge is to allocate across components and to allocate SESH overhead costsEconomic costs Extra inputs not already captured by financial costs
Contest development
Video contest (including production)Money paid for planning and implementationFor social marketing arm:

  • Personnel of CBOs/CDC (director of movie, actors, film editors)

  • Rental of professional video equipment (if applicable)

  • Building cost (office renting) for CBOs/CDC*

  • Equipment and software cost (if applicable)*

For crowdsourced arm:

  • Personnel of SESH (although all volunteer)

  • Judging opportunity cost (volunteer)

  • Steering Committee planning meeting (three 1-hour meetings)

  • Building cost (office renting)*

  • In-person promotion costs

Survey start-upMoney paid to launch the survey (start-up)

  • SESH personnel costs, to design and maintain the programme

  • Equipment cost of SESH (computer and other items)*

  • Software (Qualtrics)*

Survey implementation and interventionMoney paid to the participants (implementation)
Money paid for the software used for follow-up (implementation)

  • SESH personnel costs

Testing

  • Cost for condoms (from CDC)

  • *The cost will be annualised and we will calculate a proportion of the cost to account for items only being used the study time frame. The key idea is that some of these phases are like capital goods, where they only need to be performed once but have benefits for longer (thus requiring annualisation of costs), while the implementation phase has a life only as long as the survey is running.

  • CBO, community-based organization; CDC, centers for disease control.
