Published self-instructional techniques for stress/anger management for those with mental retardation and developmental disabilities are often impractical due to the demands of complex instructional sequencing and of applying the technique during distressing situations. The development and implementation of an adapted, self-instructional, self-control technique employing a simple, 3-step method, reinforced by iconic visual cues, will be presented. The application of this strategy in individuals with mental retardation and concurrent mental illness will be reviewed in 3 detailed clinical cases. The Stop-Think-Relax strategy is a highly versatile and easily taught method for self-control that can be successfully applied in adults with limited cognitive capacities and with coexisting psychiatric features.
