The influence of self-control on compulsive buying was addressed by several studies (e.g. Achtziger et al., 2015; Faber & Vohs, 2004). We tested if the enhancing effect of low self-control on compulsive buying can be observed in Germany and China. We tested the following hypotheses: (a) low self-control as a trait will enhance compulsive buying; (b) the influence will be the same in both cultural settings.
The strength of self-control was measured by the German (Bertrams & Dickhäuser, 2009) and by the Chinese adaptation (Unger et al., in press) of the Tangney-self-control-scale (Tangney et al. 2004). The compulsive buying tendency was measured by the German-Compulsive-Buying-Scale (Raab et al., 2005) and the Chinese adaptation of this scale (Li et al., 2014). Linear regressions revealed a highly significant influence of self-control in both of the samples (β CHINA = -.35; β GERMANY = -.39; both ps < .001) in the predicted direction.
