This study developed a high\u2010intensity mindfulness and cognitive behavioral group therapy (M\u2010CBT) program\u2014comprising mindfulness training, psychoeducation, cognitive restructuring, exposure exercises, and group\u3000sharing\u2014designed to reduce these biases.

They completed a set of questionnaires assessing SAD symptoms, cost and probability biases, fear of negative evaluation, self\u2010focused attention, depressive symptoms, subjective happiness, dispositional mindfulness, cognitive reappraisal, and suppression at pre\u2010intervention, mid\u2010intervention, post\u2010intervention, and follow\u2010up.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Analyses using linear mixed\u2010effects models revealed that high\u2010intensity M\u2010CBT produced improvements in SAD symptoms, cost and probability biases, depressive symptoms, subjective happiness, dispositional mindfulness, and cognitive reappraisal (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05).
