Metacontrol State Model Explains Additional Variance in Single-Dimension Impulsivity-Compulsivity Spectrum

Bachelor thesis | Psychologie (BSc)

Introduction The traditional approach to impulsivity and compulsivity entails that those behaviors are driven by reward sensitivity and anxiety/avoidance. According to the Metacontrol State Model by Hommel (MSM) (2015), tendencies towards either flexibility or persistence are the root of impulsive and compulsive behaviors, respectively. This study investigated whether the MSM can explain the additional variance of the single-dimension impulsivity-compulsivity spectrum in the subclinical population. Methods 41 Participants participated in the study with ages ranging from 18-35 years (M = 23.81; SD = 3.53). Data was gathered through questionnaires and experiments (S-UPPS, Stroop Task, Monetary Incentive Delay Task and Alternate Uses Task). Results The data was analyzed with a Multiple Linear Regression Analysis. The proposed model significantly predicts impulsivity and compulsivity with flexibility and persistence (F(4,32) = 5.948, p = .001, adjusted R² = .382).

Conclusion The present study supports the theory of the MSM predicting impulsivity and compulsivity. Future research is recommended to confirm this to a greater extent.Show less
