Internet Gaming Disorder Scale–Short-Form (IGDS9-SF)
The IGDS9-SF (Pontes et al., 2015) was the first brief 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 IGDS9-SF is a unidimensional tool comprising a total of 9 items reflecting all nine criteria for IGD as in the DSM-5. The IGDS9-SF was originally developed in a heterogeneous sample of 1.397 English-speaking gamers (85.1% males; mean age 27 years) recruited from 52 English-speaking online gaming forums.
This IGDS9-SF 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 IGDS9-SF 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 IGDS9-SF 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:
