There's the Short Version of the UPPS-P Impulsive Behavior Scale (SUPPS), Cyders et al. (2014), https://www.sciencedirect.com/science/article/abs/pii/S0306460314000513.

Oher scales: Eyseneck Impulsivity Questiononaire (EPQ), Taylor Manifest Scale TMAS), Rosenberg Impulsivity Scale (IS)

Sutton-Smith‚Rosenberg Impulsivity Scale -D Version .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.

Shorter is not necessarily better. The Barret scale seems the best validated and includes the BIS-15 by Spinella, used in multiples languages/cultures.

Your population/country/culture should be part of the considerations as you choose your scale..

Good luck

I prefer using the BIS-Brief, but I also think that the UPPS- P would be a great option.
