Insights
The Chinese version of the Paediatric Volitional Questionnaire (PVQ-C) is a reliable tool for assessing volition in Taiwanese preschoolers, aiding clinical judgment and interventions.
Area of Science:
- Occupational Therapy
- Developmental Psychology
- Psychometrics
Background:
- Assessing volition in children is crucial for understanding their engagement and motivation.
- The Paediatric Volitional Questionnaire (PVQ) is a key instrument, but its Chinese version (PVQ-C) requires psychometric validation for Taiwanese preschoolers.
Purpose of the Study:
- To evaluate the psychometric properties of the Chinese version of the Paediatric Volitional Questionnaire (PVQ-C).
- To establish the reliability and validity of the PVQ-C for use with preschoolers in Taiwan.
Main Methods:
- Rasch measurement model and classical test theory were employed for data analysis.
- Participants included 40 preschoolers with developmental delays and 40 typically developing preschoolers from Taiwan.
- Construct validity, item reliability, rater reliability, and convergent validity were assessed.
Main Results:
- The PVQ-C demonstrated unidimensionality, with most participant responses fitting the model.
- Acceptable item reliability (0.97), intra-rater reliability (0.412-1.0), and convergent validity (r=0.562-0.656) were found.
- 86% of items showed good test-retest reliability, and 83% of participants' responses were appropriately estimated.
Conclusions:
- The PVQ-C is a reliable and valid instrument for assessing children's volitional status.
- Findings support its use as a reference for clinical judgment and client-centered interventions.
- The validated PVQ-C can inform treatment planning and evaluation of intervention effects.
Objective:
The purpose of this study is to examine the psychometric properties of the Chinese version of the Paediatric Volitional Questionnaire (PVQ-C) for use amongst preschoolers in Taiwan.
Methods:
Forty preschoolers with developmental delays were randomly selected from northern Taiwan, along with another 40 typically developing preschoolers. The data was analysed using Rasch measurement model for construct validity and classical test theory for item reliability, intra- and inter-rater reliability, and convergent validity.
Results:
The results indicated the PVQ items of PVQ-C fit into a unidimensional continuum of volition (logit -6.63~3.05) with 2 items representing differential item functioning for diagnostic group. The person-fit statistics showed that 83% participants' response could be appropriately estimated and stratified (separation index = 1.86). Using a modified 3-point rating scale resulted in acceptable item reliability (0.97), intra-rater reliability (0.412-1.0), 86% PVQ items in test-retest reliability > 0.4, and convergent validity (r = 0.562-0.656).
Conclusions:
The PVQ-C is regarded as a reliable and valid instrument for assessing the volitional status of children, as a reference for subsequent clinical judgement, and for client-centred intervention programmes and treatment effects.
