Secondary analyses of CG severity and CG symptom and impairment questionnaire measures confirmed that CGT conferred a significantly greater change in illness severity ( @ individuals -LSB- @ % -RSB- in the CGT group vs @ -LSB- @ % -RSB- in the IPT group were still at least moderately ill -LSB- P = @ -RSB- ) , rate of CG symptom reduction ( @ ICG points per week for CGT vs @ points per week for IPT -LSB- t@ = @ ; P < @ -RSB- ) , and the rate of improvement in CG impairment ( @ work and Social Adjustment Scale points per week with CGT and @ points per week with IPT -LSB- t@ = @ ; P = @ -RSB- ) .
