The French version of the Social Interaction Self-Statement Test (SISST) wasstudied in 95 social phobia and 87 non-clinical subjects. Total scores onboth positive and negative scales significantly discriminated social phobicsfrom non-clinical control subjects. Social phobics had higher scores thancontrols on negative statements and lower scores on positive statements. Thepositive and negative subscales of the SISST for social phobic patients werecorrelated with anxiety, depression and avoidant behaviours. The negativesubscale was significantly sensitive to change in patients with social phobiareceiving cognitive behavioural therapy. Our findings showed good convergentand discriminant validity of the SISST and the sensitivity of the negativesub-scale to improvement after cognitive behavioural therapy.
