Measuring Impulsivity in Daily Life: The Momentary Impulsivity Scale (original) (raw)

It has been pointed out that the definition of BPD impulsivity would be improved by incorporating neurobehavioral models in order to bridge the research and the DSM behavioral criterion. Moeller et al. have proposed three neuropsychological diagnostic criterions related to impulsivity in psychiatric disorders: (1) rapid, unplanned reactions to stimuli before complete processing of information; (2) lack of regard for long-term consequences and;

The construction and initial psychometric evaluation of an interview assessment of clinically significant impulsivity (Lifetime History of Impulsive Behaviors; LHIB) is presented. Personality-disordered and control subjects participated by completing self-report measures of depression, anxiety and social desirability, along with self-report and laboratory analogue measures of impulsivity, and finally the LHIB. The LHIB demonstrated good to excellent internal consistency and test-retest reliability. Supporting concurrent construct validity, scores on the LHIB correlated with other selfreport measures of impulsivity. Diagnostic group differences were obtained and the LHIB evidenced concurrent validity in its ability to classify subjects by scores. No relationship was obtained between the LHIB and laboratory analogue measures. While evidence of discriminant validity was mixed, these data suggest that the LHIB may be a useful instrument for the assessment of impulsive behavior. ᮊ
Trait impulsivity in patients with mood disorders
Journal of Affective Disorders, 2007
Background: Impulsivity is a key component of the manic behavior of bipolar disorder and is reported to occur in bipolar patients as a stable characteristic, i.e. a trait. Nevertheless, impulsivity has not been widely studied in depressed bipolar patients. We assessed impulsivity in depressed and euthymic bipolar and unipolar patients and healthy controls. We hypothesized that bipolar subjects would have higher levels of trait impulsivity than the comparison groups. Methods: Twenty-four depressed bipolar, 24 depressed unipolar, 12 euthymic bipolar, and 10 euthymic unipolar patients, as well as 51 healthy subjects were evaluated with the Barratt Impulsiveness Scale (BIS). Analysis of covariance with age and sex as covariates was used to compare mean group differences. Results: Depressed bipolar, euthymic bipolar, and depressed unipolar patients did not differ, and showed greater impulsivity than healthy controls on all of the BIS scales. Euthymic unipolar patients scored higher than healthy controls only on motor impulsivity. Limitations: Higher number of past substance abusers in the bipolar groups, and no control for anxiety and personality disorders, as well as small sample sizes, limit the reach of this study. Conclusions: This study replicates prior findings of stable trait impulsivity in bipolar disorder patients, and extends them, confirming that this trait can be demonstrated in depressed patients, as well as manic and euthymic ones. Trait impulsivity may be the result of repeated mood episodes or be present prior to their onset, either way it would influence the clinical presentation of bipolar disorder.

Impulsivity in the general population: A national study
Journal of Psychiatric Research, 2012
Objective-The construct of impulsivity is an important determinant of personality differences, psychiatric disorders, and associated risk-taking behaviors. Most existing knowledge about impulsivity comes from clinical samples. To date, no study has estimated the prevalence of impulsivity and examined its correlates in the general population. Method-We analyzed data from a large national sample of the United States population. Faceto-face surveys of 34 653 adults aged 18 years and older residing in households were conducted during the 2004-2005 period. Diagnoses of mood, anxiety, and drug disorders as well as personality disorders were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version. Results-Impulsivity was common (17% of the sample), particularly among males and younger individuals, and associated with a broad range of axis I and II disorders, particularly drug dependence, cluster B, dependent and schizotypal personality disorders, bipolar disorder and ADHD. It was associated with behavioral disinhibition, attention deficits, and lack of planning. Individuals with impulsivity were more likely to engage in behaviors that could be dangerous to themselves or others, including driving recklessly, starting fights, shoplifting, perpetrating domestic violence and trying to hurt or kill themselves. They were exposed to higher risk of lifetime trauma and to substantial physical and psychosocial impairment. Conclusion-Given the association of impulsivity with psychiatric disorders and multiple adverse events, there is a need to target impulsivity in prevention and treatment efforts.
