Knowledge Item: CA-Psychosocial Services-27
Probability of Having Received a Type of Service in Different Programs Based on Length of Service Episode

This Knowledge Item illustrates the difference between the programs in terms of the likelihood that a client will have received at least one unit of a type of service after a given number of days in the program. The models shown here which emphasize the difference between the programs illustrate both differences in the programs and their treatment populations. Overall, there are significant communalities among the programs in the ways they use different kinds of services to maximize the quality of life of their clients.
