We can see all the observed values are greater than 0.61 which clearly indicated that there are very strong lodgings existed for each selected indicator for the variable of the study. All the alpha and CRs values from each group of respondents were greater than the recommended parameters value of 0.700. In the same way, the CR and AVE were also greater than 0.600 and 0.800 respectively, and also corroborates convergent validity. Fornell & Larcker (1981) also recommended the criterion to test the discriminant validity as presented in Table 3. The basic demographic characteristics of respondents such as age, qualification, occupation, family system, physical condition of children and participation in WASH programe is given in Table 4.
