315 7 MOTIVATIONAL FACTORS IN A MENTAL HEALTH GAME two linear regression analyses were performed. One analysis included the motivation to change subscales as centred independent variables and the other analysis included emotion and stress mindsets at pre-test as centred independent variables. In addition, both analyses included game choice and the interaction terms between the centred independent variables and game choice as predictors. Experimental condition was included as a control variable in both analyses. Statistical assumptions were tested and met. Motivation to change, emotion mindset, and stress mindset had no direct effect on gameplay duration. Contrary to expectations, the interactions between game choice and the motivation to change subscales, emotion mindset, or stress mindset also did not have a significant effect on gameplay duration (see Tables 6 and 7).
