Emotional correlates of the different dimensions of schizotypal personality disorder.

Two studies explored which different dimensions of schizotypal personality disorder (SPD) were associated with negative affect, attention to emotions, clarity of emotions, and emotional intensity/instability. Study 1 included 247 college students, and questionnaires were used to measure SPD. Study 2 included 225 community residents, oversampling for individuals with elevated levels of SPD, and semistructured diagnostic interviews were used to measure SPD. In both studies (a) higher levels of negative affect were associated with higher levels of both cognitive-perceptual and interpersonal symptoms, (b) cognitive-perceptual disturbances were associated with greater attention to emotion, whereas interpersonal disturbances were associated with less attention to emotion, and (c) lower levels of emotional clarity were associated with higher levels of suspiciousness.
