“…In addition, reports from three controlled (Addington et al, 2011; Bechdolf et al, 2007; McGorry et al, 2017) and four uncontrolled studies (Bechdolf et al, 2005; Evans et al, 2017; Matsumoto et al, 2018; Stafford et al, 2015) provided results of significance tests for within-group pre–post changes for individuals receiving CBT (several more noted symptom improvement, but did not provide formal significance testing results). The three reports providing data on positive psychotic symptoms (Addington et al, 2011; Matsumoto et al, 2018; Stafford et al, 2015), and one of the three providing data on negative psychotic symptoms (McGorry et al, 2017) found significant improvement. Significant improvement was also noted in four of the five reports providing data on depression (Bechdolf et al, 2005; Evans et al, 2017; McGorry et al, 2017; Matsumoto et al, 2018) and functioning (Bechdolf et al, 2005, 2007; McGorry et al, 2017; Matsumoto et al, 2018), all four reports providing data on anxiety (Addington et al, 2011; Bechdolf et al, 2005; Evans et al, 2017; Matsumoto et al, 2018), one of the two providing data on distress (Evans et al, 2017), and in the one report that provided data on quality of life (Matsumoto et al, 2018).…”
