With regards to the initiation of abstinence, it suggests that high magnitude reinforcers are effective at promoting abstinence (Schedule 4) as are escalating reinforcement magnitudes (Schedules 3 & 5).
With regards to the maintenance of abstinence the present results suggest that schedules which combine escalating reinforcer magnitude with reset contingencies (Schedule 5) are more likely to protect against relapse following a period of abstinence than any of the other scheduling arrangements investigated.
Future research attempting to isolate schedule components to assess their contribution to abstinence and combining schedule components in new ways is sorely needed.
