**2.4 Pilot test**

Before data collection, a pilot test was conducted to refine test administration procedures and determine precision of the instruments for data collection. Forty adolescent girls and boys ranging in age from 12–15 years that did not form part of the sample were recruited for the pilot test. All measurements were made according to standard procedures and the Cronbach's Alpha coefficients were calculated to determine test reliability. In all cases, the alpha coefficients ranged from 0.820 to 0.896, indicating good internal consistency [14].
