Reactivity Scale [RS-24]

Description

The Reactivity Scale [RS-24] was developed by Kohn in 1985 as a brief instrument for assessing reactivity and sensitivity to sensory stimulation, particularly among individuals experiencing pain.

Purpose

The scale aims to identify individuals who show heightened reactivity to different types of sensory experiences, not only to pain itself.

Scoring

The RS-24 consists of 24 items rated on a five-point Likert scale, from 1 = “strongly disagree” to 5 = “strongly agree.” Total scores range from 24 to 120, with higher scores indicating greater sensitivity to stimulation, preference for lower levels of stimulation, and greater distractibility.

Psychometric Properties

The scale demonstrates satisfactory internal consistency, with Cronbach’s α = 0.80. Higher reactivity scores are associated with lower pain tolerance and higher pain ratings.

Applications

The RS-24 can be used in clinical and research settings to examine sensory reactivity, pain sensitivity, and individual differences in responses to stimulation.
