Definition
Impulsivity is a personality trait characterized by the tendency to act without thinking or planning ahead. People who are impulsive tend to make rash decisions, take risks, and act on impulse. They may also have difficulty controlling their emotions and behaviors. Impulsivity can be a sign of a number of different mental health conditions, including attention deficit hyperactivity disorder (ADHD), bipolar disorder, and borderline personality disorder. It can also be a symptom of substance abuse.
Reliability
The IS is a reliable measure of impulsivity. It has been shown to have high internal consistency, test-retest reliability, and interrater reliability.
Validity
The IS is a valid measure of impulsivity. It has been shown to correlate with other measures of impulsivity, such as the Eysenck Impulsivity Questionnaire (EPQ) and the Taylor Manifest Anxiety Scale (TMAS).
The IS is a 30-item self-report questionnaire that measures impulsivity in three domains: attentional impulsivity, motor impulsivity, and non-planning impulsivity.
Attentional impulsivity is the tendency to be easily distracted and have difficulty focusing on tasks. People who are high in attentional impulsivity may have trouble following instructions, staying on task, and completing work. They may also be easily bored and have difficulty sitting still.
Motor impulsivity is the tendency to act without thinking or planning ahead. People who are high in motor impulsivity may act impulsively, make rash decisions, and take risks. They may also have difficulty controlling their emotions and behaviors.
Non-planning impulsivity is the tendency to be disorganized and have difficulty thinking ahead. People who are high in non-planning impulsivity may have trouble planning ahead, organizing their thoughts, and making decisions. They may also be forgetful and have difficulty managing their time.
The IS is a useful tool for assessing impulsivity in a variety of settings, including clinical, research, and educational settings. It can be used to diagnose impulsivity disorders, assess the severity of impulsivity, and track changes in impulsivity over time. The IS can also be used to develop treatment plans and interventions for people with impulsivity disorders.
If you are concerned that you or someone you know may have an impulsivity disorder, please talk to a doctor or mental health professional.
