“…Some studies showed that satisfaction and frustration are not diametrically opposed to one another when taking correlates into account (e.g., Bartholomew, Ntoumanis, Ryan, Bosch, et al, 2011;Chen et al, 2015;Costa, Ntoumanis, & Bartholomew, 2015;Krijgsman et al, 2017;Nishimura & Suzuki, 2016), which would support the hypothesis that these are distinct factors. Results of yet another group of studies provided support for the continuum hypothesis by demonstrating completely opposite patterns of associations between need satisfaction/frustration and different correlates (e.g., Brenning, Soenens, Mabbe, & Vansteenkiste, 2019;Campbell et al, 2019;Costa, Gugliandolo, Barberis, & Larcan, 2016;Landry et al, 2016;Schultz, Ryan, Niemiec, Legate, & Williams, 2015). It appears that the field is far from unified.…”
