The Infant Behavior Questionnaire (IBQ and IBQ-R)
The original IBQ was developed by Dr. Rothbart in the early 1980s and first reported in the 1981 Child Development article, "Measurement of Temperament in Infancy" (Rothbart, 1981).This early form of the instrument assessed 6 domains of infant temperament (activity level, soothability, fear, distress to limitations, smiling and laughter, and duration of orienting).The items on the IBQ ask parents to rate the frequency of specific temperament-related behaviors observed over the past week (or sometimes 2 weeks).
In 1998, Dr. Rothbart and her colleague, Dr. Masha Gartstein, revised the IBQ by refining the original scales and adding several new scales. The new instrument is referred to as the IBQ-Revised (IBQ-R). Short (91 items; 14 scales) and Very Short (36 items; 3 broad scales) forms of the IBQ-R were developed by Sam Putnam and colleagues in 2008.

The IBQ and IBQ-R have been designed to measure temperament in infants between the ages of 3 and 12 months.? The IBQ-R assesses the following dimensions of temperament:
- Activity Level: Movement of arms and legs, squirming and locomotor activity.
- Distress to Limitations: Baby's fussing, crying or showing distress while a) in a confining place or position; b) involved in caretaking activities; c) unable to perform a desired action.
- Approach: Rapid approach, excitement, and positive anticipation of pleasurable activities.
- Fear: The baby's startle or distress to sudden changes in stimulation, novel physical objects or social stimuli; inhibited approach to novelty.
- Duration of Orienting: The baby's attention to and/or interaction with a single object for extended periods of time.
- Smiling and Laughter: Smiling or laughter from the child in general caretaking and play situations.
- Vocal Reactivity: Amount of vocalization exhibited by the baby in daily activities.
- Sadness: General low mood; lowered mood and activity specifically related to personal suffering, physical state, object loss, or inability to perform a desired action.
- Perceptual Sensitivity: Amount of detection of slight, low intensity stimuli from the external environment.
- High Intensity Pleasure: Amount of pleasure or enjoyment related to high stimulus intensity, rate, complexity, novelty, and incongruity.
- Low Intensity Pleasure: Amount of pleasure or enjoyment related to situations involving low stimulus intensity, rate, complexity, novelty, and incongruity.
- Cuddliness: The baby's expression of enjoyment and molding of the body to being held by a caregiver.
- Soothability: Baby's reduction of fussing, crying, or distress when the caretaker uses soothing techniques.
- Falling Reactivity/Rate of Recovery from Distress:Rate of recovery from peak distress, excitement, or general arousal; ease of falling asleep.
