The present systemic intervention is based on the following principles of living systems development: 1. The law of experience (Ashby, 1958). The lack of stimulation leads to functioning decrease. 2. The law of over-load of information stress (Miller, 1978). Each living system has a certain ability to process information. If the environmental information is much more than the ability to process them, then there is an overload of information stress, while if the environmental information is less than the ability to process them, then there is an under-load of information stress. 3. Development through order increase (Prigogine & Stengers, 1984). The development in living systems contains order increase.

4. The law of optimal variety (Paritsis, 1992). The increase of the development rate is succeeded when the variety of environmental components is high enough so as not to cause overload of information stress. 4. The law of optimal variety (Paritsis, 1992). The increase of the development rate is succeeded when the variety of environmental components is high enough so as not to cause overload of information stress. 5. The combination of variety and order in the development (Paritsis, 1993,1999). The increase of variety and at the same time the increase of order contribute to speeding up the rate of development. This happens as the increase of order reduces the overload of information stress. 5. The combination of variety and order in the development (Paritsis, 1993,1999). The increase of variety and at the same time the increase of order contribute to speeding up the rate of development. This happens as the increase of order reduces the overload of information stress. Target of the study According to the above mentioned principles it is concluded that the gradual (optimal) increase of the amount and variety of stimulation in parallel with the gradual (optimal) increase of organization and order in the environment contributes to the maximization of functioning bettering.

In this context, the hypothesis of the present study was the following one: An intervention based on the above principles that is applied in individuals with profound mental retardation will result in adaptive behavior improvement in a period of 6 months.

METHOD EXPERIMENTAL DESIGN Research type: Action research Repeated Measures: Measure Α: 6 months before participants leave the institution for the boarding house Measure Α: 6 months before participants leave the institution for the boarding house Measure Β: 1 months after moving to the boarding house Measure Β: 1 months after moving to the boarding house Measure C: 6 months after moving to the boarding house Measure C: 6 months after moving to the boarding housePARTICIPANTS Sex: 9 men and 4 women with profound/mild mental retardation and behavior problems Age: 19 – 44 years old (mean= 29,6 years) Mean institutional care: 18,3 years in the Child Psychiatric Hospital of Athens.

ASSESSMENT MATERIALS Vineland Adaptive Behavior Scales (Sparrow, Balla & Cicchetti, 1984) Since adaptive behavior is a composite of various dimensions, the test measures 4 domains: Since adaptive behavior is a composite of various dimensions, the test measures 4 domains: The Communication Domain: It evaluates the receptive, expressive, and written communication skills. The Communication Domain: It evaluates the receptive, expressive, and written communication skills. The Daily Living Skills Domain: It measures personal behavior as well as domestic and community interaction skills. The Daily Living Skills Domain: It measures personal behavior as well as domestic and community interaction skills. The Socialization Domain : It assesses play and leisure time, interpersonal relationships, and various coping skills. The Socialization Domain : It assesses play and leisure time, interpersonal relationships, and various coping skills. The Motor Skills Domain: It measures both gross and fine motor skills.

DISCUSSION Comparison between measurements Α and Β: Non significant differences Comparison between measurements Α and Β: Non significant differences Comparison between measurements B and C: Statistically significant differences in the domains of: Communication (receptive), Daily living skills and Socialization Comparison between measurements B and C: Statistically significant differences in the domains of: Communication (receptive), Daily living skills and Socialization The above results may be due to: The participants lived for a long period in an environment with small stimulation The participants lived for a long period in an environment with small stimulation The intervention helped the participants to activate the possibilities they had. The intervention helped the participants to activate the possibilities they had. The systemic method applied was based on General Systems Theory principles and it seems that it results in adaptive functioning improvement, as was theoretically supposed (Paritsis, 1993).

Conclusions The results are compatible with the principles on which the hypothesis was based on and they reinforce them The results are compatible with the principles on which the hypothesis was based on and they reinforce them The above method needs further control and development The above method needs further control and development Η πιο πάνω μέθοδος βασισμένη σε συγκεκριμένες συστημικές αρχές καλεί για περαιτέρω εφαρμογή της προς τη κατεύθυνση του ελέγχου και της ανάπτυξής της, αλλά και σε κλινικό επίπεδο προς την κατεύθυνση της βελτίωσης των ατόμων με νοητική υστέρηση Η πιο πάνω μέθοδος βασισμένη σε συγκεκριμένες συστημικές αρχές καλεί για περαιτέρω εφαρμογή της προς τη κατεύθυνση του ελέγχου και της ανάπτυξής της, αλλά και σε κλινικό επίπεδο προς την κατεύθυνση της βελτίωσης των ατόμων με νοητική υστέρηση
