The Positive Automatic Thoughts Questionnaire (ATQ-P) was designed to assess the frequency of positive self-statements. This article reports original data and reviews other studies that have used the ...ATQ-P. These data show that the reliability and the norms of the ATQ-P appear stable and that the ATQ-P is inversely associated with negative affective states but unrelated to conditions such as medical condition not accompanied by psychological distress. The ATQ-P also shows adequate convergent and discriminate validity. Data also show that the ATQ-P conforms to theoretical predictions of the states-of-mind model. Finally, these data show that the ATQ-P is sensitive to cognitive changes. In sum, the results suggest that the ATQ-P is an effective measure of positive self-statement frequency.

Controlled processing, response inhibition, and set
adoption were examined in 51 HIV-1 infected participants and 21
uninfected controls who were administered a vocal reaction time (RT)
version of the ...Stroop task (Stroop-RT;
J. R. Stroop, 1935
) as well as the traditional
100 item paper-and-pencil version. Response set expectancies on the
Stroop-RT were manipulated by presenting 50% of trials
in homogenous blocks and randomly varying the stimulus type during
the remaining trials. As hypothesized, HIV seropositive (HIV+)
participants were significantly slower than HIV seronegative
controls on both versions of the Stroop. Significant interference
effects were apparent on the paper-and-pencil version of the Stroop,
but were not as prominent on the Stroop-RT. The HIV+
participants did profit from the blocking manipulation on the
Stroop-RT, suggesting that set adoption is retained in HIV
infection. These data suggest that HIV infection may result in
deficient response inhibition, possibly secondary to frontostriatal
dysfunction and dopaminergic alterations.
