Psychometric study of Chinese version of the Pediatric Volitional Questionnaire for preschoolers in Taiwan

Abstract

Objective：

Occupational therapy promotes the clients' functions through engaging them in the purposeful and meaningful occupations. Lack of motivation to participate in occupations would obstuct the individual to perform adaptively. Understanding client's motivational status provides us a picture of the mechanism which results in certain behaviors.

Therefore, clearly defined motivational behaviors could assist clinicians to choose appropriate programs to promote the treatment effect. Literature indicates that an adequate, standardized, and theory-based assessment to evaluate client's motivational status is important. The purpose of this study is to examine the psychometric properties of the Chinese version of the Pediatric Volitional questionnaire (PVQ-C) for preschoolers in Taiwan.

Methods:

The PVQ-C was translated and back-translated according to scholars' suggestions. Forty normal preschoolers and 40 preschoolers with developmental delayed were randomly selected from medical institutions and kindergartens of north Taiwan. Subjects were observed and videotaped in 2 situations (school vs. motivational situation). The researcher then rated their performance by watching the videotapes. The data was analyzed using Rasch measurement model and traditional test theory.

Results:

The results revealed that all items of the PVQ-C defined a unidimensional construct of volition. The PVQ-C correlated with the developmental test moderately. It also showed that the PVQ-C had acceptable test-retest, intra-rater reliability and internal consistency. The children with developmental delay had significantly lower Rasch score on the PVQ-C as compared with the nomal group when controlled for confounding variables (p<.01).

Conlusion:

This study supports that the PVQ-C is a reliable and effective clinical assessment tool, which can provide useful information about the client’s volition status as reference to clinical judgment, intervention program, and progression of treatment.
