Insights
The Infant Behavior Questionnaire - Revised (IBQ-R) is reliable in newborns. Its factor structure remains stable from 2 weeks to 12 months, supporting early infant temperament assessment.
Area of Science:
- Developmental Psychology
- Infant Behavior Research
Background:
- Temperament is crucial for infant development.
- The Infant Behavior Questionnaire - Revised (IBQ-R) is widely used for infants 3-12 months.
- IBQ-R reliability and factor structure in infants under 3 months were previously unexamined.
Purpose of the Study:
- To assess the reliability of the IBQ-R at 2 weeks of age.
- To analyze the IBQ-R factor structure from 2 weeks to 12 months of life.
Main Methods:
- A longitudinal study with repeated measures was employed.
- 300 mothers completed the IBQ-R at infant ages of 2 weeks, 3 months, 6 months, and 12 months.
Main Results:
- Reliability analyses (Cronbach's alpha, McDonald's omega) indicated good internal consistency for IBQ-R dimensions.
- A consistent three-factor structure (surgency/extraversion, negative affectivity, orienting regulation) was identified across all time points.
- Higher rates of non-applicable responses were noted in specific scales at 2 weeks.
Conclusions:
- The IBQ-R is suitable for use in the early weeks of life.
- The factor structure of the IBQ-R is stable throughout infancy, validating its use across different age groups.
Background:
Temperament characteristics are key elements for infants' development. The Infant Behavior Questionnaire - Revised (IBQ-R) is one of the most used measures to assess temperament in infants aged between 3 and 12 months. Its reliability and factor structure have not yet been examined in infants younger than 3 months.
Aims:
To analyze the reliability of the IBQ-R at 2 weeks and the IBQ-R factor structure from 2 weeks to 12 months of life.
Method:
A longitudinal repeated measures design was used. Three hundred mothers completed the IBQ-R when their infants were 2 weeks, and 3, 6 and 12 months.
Results:
At 2 weeks the proportion of "non-applicable" responses was higher in duration of orienting, high intensity pleasure, approach and smiling and laughter scales. The Cronbach's alpha for the IBQ-R dimensions ranged between 0.62 and 0.63 and the McDonald's omega ranged between 0.67 and 0.80, all dimensions exhibited a mean-scale correlation above 0.15, and more than half of the scales revealed a scale-dimension correlation higher than 0.30. The same factor structure was found at 2 weeks, and at 3, 6, and 12 months: surgency/extraversion, p < 0.001, negative affectivity, p < 0.001, and orienting regulation, p = 0.007.
Conclusions:
The IBQ-R may be applied in the first weeks of life and its factor structure remains stable when applied across different ages throughout infancy.
