Development and Validation for Diagnosing IGD in Adolescents

1. Understanding of theoretical orientation of each test before applying the tests on the patients is very important. The first test as described by Koo et al. (2017) was a clinical interview for diagnosing of internet gaming disorder. It is based on the theory that internet gaming disorder is the cognitive and behavioural pattern which is persistent and consistent. The other test was for the videogame addiction scale for children by Yilmz et al. (2017). This is based on the theoretical framework thataddiction has core features which are inability to control action and continuance of behaviour in spite of negative behaviour.

2. The first test as described by Koo et al. (2017) was a clinical interview for which the test-retest reliability was conducted with 16 participants and the interviewers had a good level of agreement. They used K-scale for measurement of concurrent validity and it showed good validity. Whereas in the test developed by Yilmz et al. (2017) was assessed for construct validity an item-correlation was conducted by use of correlation analysis and Cronbach’s alpha reliability analysis. From the results, it can be concluded that both the tests are valid and reliable while it might need to be checked in case of translation.

3. The first test as described by Koo et al. (2017) was clinical interview when it is put to use in the future the limitation that can be seen is that there are various questionnaires used in the development of the current scale. When this is being used each time, the level of agreement of the interviewer needs to be established also linguistic validity and reliability need to be conducted. The test developed by Yilmz et al. (2017) was done in one subset of Turkish children while checking for external reliability large and heterogeneous sample is required.
