Construct validity of questionnaires for the original and revised reinforcement sensitivity theory

Area of Science:

• Psychology
• Personality Science
• Psychometrics

Background:

• Reinforcement Sensitivity Theory (RST) describes individual differences in motivation and emotion.
• Existing questionnaires for original and revised RST have varying psychometric properties.
• The Conflict Monitoring Questionnaire (CMQ-44) offers a novel approach to measuring RST constructs.

Purpose of the Study:

• To evaluate the psychometric properties and construct validity of RST questionnaires.
• To assess the measurement capabilities of the CMQ-44 in relation to established RST scales.
• To provide evidence for the reliability and validity of these personality measures.

Main Methods:

• Confirmatory Factor Analysis (CFA) was used to assess model fit.
• Parcel-level psychometric properties and internal consistencies were examined.
• Correlations between factor scores of different RST measures were analyzed.

Main Results:

• CFA models demonstrated very good fit for Carver-White BIS/BAS scales, RST-PQ, rRST-Q, and CMQ-44.
• Internal consistencies ranged from moderate to excellent.
• CMQ-44 cognitive demand correlated positively with BIS and BAS factors, while negative consequences and response adaptation correlated negatively with trait-BAS.

Conclusions:

• The studied RST questionnaires, including the CMQ-44, exhibit strong psychometric properties.
• The CMQ-44 effectively measures cognitive demand related to BIS and BAS systems.
• Performance monitoring, a factor of CMQ-44, extends the RST trait space and relates to trait-BAS.
