“…The few explored mediating variables are invested time on task (Stoeber, Chesterman, & Tarn, 2010), perceived pressure to be perfect (Stoeber& Renner, 2008) and achievement goals (Stoeber et al, 2015). However, in the present research, work motivation has been employed as a mediator that cause perfectionist striving and performance relationship because Stoeber, (2013) argued that work motivation is a variable that elaborate the positive association of perfectionism with workaholism and other positive work behaviors because perfectionists always work with determination and motivation which in turn leads towards positive performance (Galdeano, Ahmed, Fati, Rehan & Ahmed, 2019). This argument has been further strengthen by other researchers (Hall, Hill, & Appleton, 2012;Mills & Blankstein, 2000;Stoeber, Feast, &Hayward, 2009;Van Yperen, 2006) who have confirmed the significant positive association of perfectionist striving with motivation and all types (introjected regulation, identified regulation, intrinsic motivation and extrinsic motivation) proposed by self-determination theory (SDT), suggesting that perfectionist are highly motivated through the variety of motivations.…”
