Note. Correlations that appear in boldface in the top portion of each matrix were used in tests of one-factor model. These matrices were used for tests of the equality of correlations across groups. The tests of the one-factor models were conducted on matrices with slightly larger samples. Choice behavioral choice (square-root transformed); Affect affective valence; Consequences SCQ-B, the brief version of the Smoking Consequences Questionnaire; Urge Self-reported composite urge (square-root transformed); Ad lib ad lib characteristics of smoking; RT latency response-time latency.
