In the present study, we investigated affective and psychotic stress reactivity as well as its link with psychotic symptoms and psychopathology in youths with 22q11.2 deletion syndrome (22q11DS), a neurogenetic condition associated with a high risk for psychosis.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722004019_sec_a2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>A 6-day ecological momentary assessment protocol was used to assess perceived daily-life stress as well as affective and psychotic reactivity to stress in participants with 22q11DS (<jats:italic>n<\/jats:italic> = 38, age = 18.4) and healthy controls (HC; <jats:italic>n<\/jats:italic> = 53, age = 19.1).

The groups did not differ in affective or psychotic reactivity to stress, but individuals with 22q11DS who reported increased affective reactivity to social stressors showed more severe positive psychotic symptoms (<jats:italic>r<\/jats:italic><jats:sub>s<\/jats:sub> = 0.505, <jats:italic>p<\/jats:italic> = 0.008).
