The purpose of the study was to provide rehabilitative services3. As of December 2002, there assess the developmental stage of children with disability. were a total of 93 health centers in Malaysia providing Secondary data from the pilot project conducted by the rehabilitation services for children with disability4. In the Family Health Development Division, Ministry of Health year 2002 alone, there were a total of 1,387 disabled children Malaysia was used in this study. The study period was for six below the age of seven years detected at the health clinics4. In months from 1st August 2004 until 31st January 2005.

Results showed more boys than girls were affected with a ratio of 6:4. The mean total SGS score increases as the age of Studies from the developed world have used different the child increased. The score was highest in delayed speech developmental assessment tools to describe the cases and lowest in cerebral palsy cases. The performance developmental achievement among children with disability5-7. among children with delayed speech was the highest while However, most of the studies concentrate on one particular children with cerebral palsy were the lowest. There was a disability and on one particular skill area. In Malaysia, there statistically significant difference between the major ethnic has been no study to quantify or score development among groups in delayed speech and attention deficit hyperactive children with disability. disorder. The objectives of this study were: KEY WORDS: 1.

To score the developmental assessment among children with disability using an appropriate assessment tool. 3. To determine any significant difference in the INTRODUCTION developmental assessment score among children with According to the World Health Organization (WHO), disability in the three major ethnic groups. children with disability could be defined as ‘any child unable to ensure by himself wholly or partly, the necessities of a normal individual and or social life, as a result of a deficiency MATERIALS AND METHODS either congenital or not, in his physical or mental This is a cross-sectional study investigating the profile of capabilities’1. WHO stated that 10% of the population in any children with disability registered with the primary health country around the world has some form of disability. It has care clinic in Malaysia. Secondary data from the pilot project been estimated that among the 10% of the population with conducted by the Family Health Development Division, disability, one third are among children less than 15 years Ministry of Health Malaysia was used in this study.

SGS II is a developmental screening procedure autism (r = 0.063) (Table II). which was based firmly on the well-known and well- respected developmental sequences designed by Dr Mary Table III showed the percentage of mean SGS scores in Sheridan8. Supplemented by a few well-tried items not relation to the mean achievable scores according to the included in Mary Sheridan’s work, SGS II was the fruit of chronological age of the cases. A higher percentage means several years of research, development and trial on children that the child’s developmental age is closer to their throughout the United Kingdom. It provides information on chronological age ability. Delayed speech scored the highest whether the child is developing normally and identifying percentage (ranging from 61.0% to 99.4%) in seven out of the which skill areas the child is delayed in. eight skill areas while cerebral palsy scored the lowest (ranging from 14.7% to 36.9%) in all the eight skill areas. The inclusion criteria in this study include all of the cases Among the different skill areas, cognitive skill had the lowest from the pilot study. The exclusion criteria include cases percentage (ranging from 14.7 to 60.2) in all the types of from East Malaysia, cases that are not Malaysian and cases at disability except for delayed speech.

As for II was assessed in eight skill areas. The skill areas include attention deficit hyperactive disorder, significant differences locomotor, manipulative, visual, hearing and language, were detected among Malay-Chinese (p=0.038) and Malay- speech and language, interactive social, self-care social and Indian (p=0.015) mean pairs. cognitive.
