Description

This study focuses on the development and initial validation of the Anger Expression Scale for Children, designed to assess how anger is expressed in children. The scale was tested on two groups of children: healthy children and children with cancer, to evaluate its suitability across different population samples.

Data Analysis and Usage

Data analysis was performed using statistical methods to assess the reliability and validity of the scale. The data usage involved comparing the responses between the two groups of children to identify any differences or similarities in anger expression.

Objective

The primary objective of the study was to calibrate and initially validate the Anger Expression Scale for Children to ensure that it is reliable and valid for use in different samples of children, including those suffering from serious illnesses such as cancer.

Calibration

The calibration of the scale was carried out using factor analysis methods and examining the internal consistency of the subscales. This calibration aimed to ensure that the scale’s items are appropriately structured to reliably measure the various dimensions of anger expression in children.
