Discriminant Ability of Gravitational Insecurity (GI) Assessment

Objective

This study examined the reliability and validity of the Gravitational Insecurity (GI) Assessment (Revised Version) among Indian children.

Method

The GI Assessment consists of nine items rated on two behavioral categories - Emotional Responses (ER) and Postural Responses (PR). Participants were 28 children with GI, 5-10 years of age, and a matched group of typically developing children.

Results

Discriminant analysis results found that both the behavioral categories (F(1, 54)=1346.09, ë =0.039;F(1, 54)=357.89, ë =0.131) and all the nine items correctly classified the two groups at 100% level. A stepwise discriminant analysis revealed that the Emotional Response category classified GI children at 96.4% and the Postural Response category classified GI children at 100% from typically developing children

Conclusion

The GI assessment is a reliable and valid measure for identifying children with Gravitational Insecurity. It can be used as assessment tool as well as outcome measure to find out effectiveness of intervention program.
