Relationships between Self-Reported Impaired Control and Impulsivity in Adolescents and Young Adults

Authors	Yr	Sample	IC scale	Impulsivity scale	Summary of findings
Chung & Martin	02	Adolescents: clinical setting & community	DSM-IV criteria, via interview	Eysenck I.7	Moderate, significant correlation between “larger/longer” criterion & impulsivity. Non-significant correlation between impulsivity and “quit/control”
Leeman, Fenton, Kulesza, Stewart, Taylor, & Copeland	09	Undergrads, alcohol users	ICS, Part 2	BIS-11	Moderate, significant correlation between IC and all three subscales as well as total BIS-11 score.
Nagoshi	99	Undergrads, alcohol users	ICS, Part 3	Eysenck I.7	Moderate, significant correlation
Patock-Peckham, King, Backer-Fulghum, Morgan-Lopez, & Leeman	11	Undergrads	ICS, Part 3	UPPS	Significant path from negative urgency score to impaired control. No other significant paths in SEM to predict drinking quantity and alcohol-related problems.
Patock-Peckham, King, Morgan-Lopez, Ulloa & Filson-Moses	11	Undergrads	ICS, Part 3	Eysenck I.7	Significant path from impulsivity to impaired control among both men and women in a multiple group SEM model to predict alcohol-related problems.
Patock-Peckham & Morgan-Lopez	06	Undergrads, alcohol users	ICS, Part 3	Eysenck I.7	Significant path from impulsiveness to impaired control in SEM model to predict alcohol frequency/quantity of use and alcohol-related problems

Note. All studies were cross-sectional. Moderate correlation (0.30–0.49). Yr = year, IC = impaired control, Eysenck I.7 = impulsiveness subscale of the Eysenck Personality Questionnaire, version 7 (Eysenck, Pearson, Eastin, & Allsopp, 1985), ICS = Impaired Control Scale, BIS-11= Barratt Impulsiveness Scale, version 11 (Patton, Stanford, & Barratt, 1995), UPPS = UPPS Impulsive Behavior Scale, original version (Whiteside & Lynam, 2001), SEM = structural equation model. Part 2 of the ICS assesses past difficulties limiting alcohol use. Part 3 of the ICS measures beliefs about future difficulties
