The model of once-a-week training sessions is considered ideal; however, the emotional needs, availability, or schedule of parents or children may necessitate consideration of other sequences of training sessions. The once-a-week Child-Parent Relationship Therapy (CPRT) model is simply to provide a complete listing of the possible variations in scheduling the 10-session model of CPRT. The weekday schedule for some families is so hectic and stressful that they have difficulty making a commitment to 10 weeks of training. The one potential problematic factor with typical format is arranging for someone to babysit the child while the therapist is training the parent or couple. Intensive CPRT training was found to be as effective as intensive individual play therapy and intensive sibling group play therapy conducted by professional play therapists. The use of toys to demonstrate a child’s behavior in a play session and corresponding recommended responses is not possible via the telephone, nor can tracking skills be demonstrated.
