Exploring the reliability of the Kilifi Development Inventory (KDI) for African children between the ages 6-35 months.

Abstract

There is a dire need for psychological tests to be standardized for the African child and for appropriate norms to be developed. This study is part of two larger studies that began in 2008, namely the National Early Learning Standards Age Validation Study (NELDS) (Kvalsvig, Govender & Taylor; 2008) (Principal Investigator – Dr. S. Kauchali), and the INSTAPA Work Package 6 Study (Kvalsvig, Govender & Taylor; 2008) (Principle Investigator – Dr. J.D. Kvalsvig). This study considers aspects of the Kilifi Development Inventory (KDI) as a measurement tool used to provide a structured and standardized procedure for monitoring the cognitive development of children from the age of 6 to 35 months. It is situated in the positivist paradigm and has adopted the classical test theory in attempting to establish the reliability of the Kilifi Developmental Inventory. Stratified purposive sampling techniques were used to select the South African sample, which comprised 120 participants categorized by gender (males and females), age (6 – 18 months and 18 – 35 months) and area (urban and peri urban/rural). The internal reliability of the KDI was investigated. Results from the data analysis (using SPSS 18.0) suggest that the measurement tool as a whole had inadequate internal reliability and therefore, further investigations and modifications have to be undertaken in certain subtests of the measurement tool before the assessment tool can be standardized for the South African population.
