Construct and Concurrent Validity of two Scales Designed to Measure Reinforcement Sensitivity

Two studies assessed construct and concurrent validity of two scales designed to measure reinforcement sensitivity. non-probabilistic samples college students from Mexico City were used. The first study showed that while the BIS/BAS may possess validity, they lack in one; conversely, SPSRQ did not show but evidence one. Convergent was using self-report questionnaires. second BAS predict response distribution, IOWA-GT, a way is consistent with Reinforcement Sensitivity Theory (RST); this case BIS scale. results suggest either developed assess RST, or theory itself (or both) require thorough revision.
