The Internet Gaming Disorder Test (IGD-20 Test)
The IGD-20 Test (Pontes et al., 2014) was the first standardized psychometric tool to assess Internet Gaming Disorder (IGD) according according to the nine Internet Gaming Disorder (IGD) criteria as suggested by the American Psychiatric Association in the latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
The IGD-20 Test was developed in a heterogeneous sample of 1.003 English-speaking gamers (85.2% males; mean age 26 years) from 57 different countries were recruited via online gaming forums.
The IGD-20 Test has a total of 20 items and conceptualizes IGD according to the six first-order latent domains well-established in behavioral addictions: ‘Salience‘, ‘Mood Modification‘, ‘Tolerance‘, and ‘Withdrawal Symptoms‘, ‘Conflict’, and ‘Relapse‘.
This IGD-20 Test had its psychometric properties extensively investigated and several studies have provided satisfactory results at several levels, such as:
Construct validity (i.e., factorial, convergent); (ii) criterion-related validity; (iii) concurrent validity, (iv) cross-cultural validity. The IGD-20 Test has also been shown to be reliable according to several indicators of reliability [all information about the validity of the scale can be found in the original study]
The IGD-20 Test is widely used in research on IGD and several cross-cultural psychometric studies to validate the test in other languages were conducted. Languages in which the test has been developed so far include:
