Development of a short form of the compulsive internet use scale in Switzerland.

ABSTRACT:

Objectives

The study aims to develop a short form of the compulsive internet use scale (CIUS), which can be used in multitopic and general population health surveys and is invariant across different sexes, linguistic regions, and ages.

Methods

Two general population surveys from 2013 and 2015 were used as learning (n = 1,371) and validation samples (n = 1,550), respectively. Reducing items from the original CIUS was based on the following: (a) correlated errors between items, (b) differential item functioning, and (c) measurement invariance. Methods used item response theory and latent confirmatory factor analysis for ordinal variables.

Results

The eight-item short form maintained the five dimensions of the original scale and was metric and mostly scale invariant for
