Allen's Cognitive Disabilities Model (CDM)
The Allen’s Cognitive Disabilities Model (CDM) emphases on the integration of the cognitive functional ability and the level of activities that clients are able and willing to perform. Interventions using this model can take place individually or in group. When implementing the intervention, therapists consider each client’s needs and implement changes in task accordingly. In group sessions, each client’s cognitive mode of performance is considered individually and adapted to the modified task with appropriate level of required cognitive functional ability.
