Psychometric Properties of Young’s Internet Addiction Test in Nigeria

 In 2018, the Nigerian Communication Commission affirmed that more than 100 million Nigerians made use of the Internet. A good percentage of internet usage is maladaptive. A valid, reliable, and socio-culturally sensitive assessment instrument is essential to study internet usage patterns in Nigeria. Young’s Internet Addiction test (IAT) has been validated in many countries, but not in Nigeria.

 This study aimed to validate IAT to determine psychometric properties acceptable in a Nigerian population.

 A total of 184 Nigerian University undergraduates (77 males and 107 females), mean age = 20.5, were purposively drawn, and they responded to IAT, the Smartphone Addiction Scale-Short Version (SAS-SV), and the Bergen Facebook Addiction Scale (BFAS).

 The Cronbach’s α of the six IAT factors ranged from 0.25 (anticipation) to 0.69 (salience). The observed overall Cronbach’s α coefficient of 0.79 was obtained for IAT. The corrected item-total correlations ranged from 0.73 to 0.84. The concurrent validity score was observed to be r = 0.54 between IAT and SAS-SV and r = 0.58 between IAT and BFAS. A significant positive correlation was equally observed between the IAT and BFAS factors, ranging from conflict (r = 0.322, P = 0.000) to relapse (r = 0.488, P = 0.000). The new norm determined for IAT in the Nigerian population was ≥ 38.5 for males and ≥ 40.8 for females.

 IAT is gender-sensitive and has acceptable psychometric properties for the Nigerian population.
