Final answer:
Community Reinforcement (CR) and Contingency Management (CM) face long-term sustainability issues due to the difficulty in maintaining the required continuous monitoring, adjustments, and need for ongoing funding for effective program implementation and impact assessment.
Step-by-step explanation:
The drawbacks to Community Reinforcement (CR) and Contingency Management (CM) include challenges in their application over the long-term. CR and CM are behavioral treatment approaches that involve changing an individual's environment to encourage sober and healthier behavior patterns and providing tangible rewards to reinforce positive behavioral changes, respectively. However, these strategies often require continuous monitoring, adjustments, and funding, which can be difficult to sustain over time.
Implementing these interventions for a long-term period can pose difficulties in consistently conducting need and asset assessments, which are essential for planning effective programming and measuring the long-term impact of the interventions. Without comprehensive evaluations and the flexibility to adapt to changing circumstances, it can be hard to maintain the effectiveness of CR and CM programs and to justify continuous investment in them
