Self-Determination Theory research has found that autonomous motivation, compared to externally controlled motivation, is associated with psychological well-being (Ryan, Huta, & Deci, 2008). We tested whether a cognitive manipulation -- thinking about daily activities in terms of “I get to” rather than “I have to” – can increase intrinsic motivation and well-being. We randomly assigned 100 undergraduates to record their daily activities for four days. One group was instructed to use the mindset “I get to” do the activities; the second group used the mindset “I have to” do the activities; and the third group was a measurement-only control group. Dependent variables included intrinsic motivation (Situational Motivation Scale); satisfaction of basic psychological needs (Basic Psychological Need Satisfaction and Frustration Scale-in General); daily affect (Scale of Positive and Negative Experience); mindfulness (Mindful Attention Awareness Scale); feelings of material and time affluence (Material Affluence Time Affluence Scale); and level of academic engagement (Utrecht Work Engagement Scale). We discuss the extent to which a “get to” mindset was associated with intrinsic motivation, fulfillment of psychological needs, positive affect, negative affect, mindfulness, sense of subjective time affluence, and level of engagement in academic pursuits.
