Impulsivity Self-Related Study

Introduction
Impulsivity is one characteristic is associated with various addictions. Impulsivity is one of the symptoms that are seen with ADHD, impulse control disorders, and bipolar disorder. Components of impulsivity consist of inattention, hyperactivity, failure of control and risk taking. Research shows that impulsivity self-report and behavioral measures are correlated in several studies. The purpose of the study was to investigate the correlation between impulsivity self-report and behavioral measures in individuals with ADHD. Two groups were compared between individuals with and without history of diagnosis of ADHD. Hypotheses included a multi-component solution, which self-report and behavioral measures would be present in different

areas with little overlap, and that impulsivity with attention would predict the group assignment.
Methods
Participants included 195 undergraduates but twenty were taken out due to self-reporting a psychiatric disorder different from ADHD.

The BIS, Behavioral Inhibition/Behavioral Approach System Care, the Impulsive Sensation Seeking Subscale, and the Stroop Color Word Interference Task were administered, except for the BART. Self-report measures were carried out by the BIS while the behavioral measures were obtained by completing the BART assessment. Scores were changed into z scores for each of the measurements. A principal components analysis known as PC was conducted. The parallel analysis was conducted with fifteen variables. Also, a regression analysis was done to predict the group assignment with PCA components as predictors.
Results
The Kaiser Meyer Olkin measure showed that the analysis was acceptable and the Bartlett's test was significant with a chi-square value of 943.16 and a p value less than 0.001. No behavioral measurements loaded on the three components. Between each component, correlations were found when analyzing self-report measures, BAS subscales, and the remaining self-report measures. A logistic regression was conducted and the overall success of the prediction included 85.3%. A second regression was conducted with BART and no significant predictors.

Discussion
The findings of this study showed that there was a 3-component solution. The hypothesis was supported by the self-report and behavioral measures of impulsivity's little overlap between the variables, a result that is supported by previous research. The findings of the PCA were consistent with research examining the impulsivity measures. Example includes the impulsiveness with attention variable is consistent previous study although there was a different method used. The implementations of multiple assessment measurement are recommended to investigate impulsivity much more thoroughly and examine variables. Limitations of the study included a small subset of both measures of impulsivity and the use of small samples. Literature is supported by results, implying that studying impulsivity is complex with findings with three different components as used in this study.
