The Development and Test-Retest Reliability for the Clients with Depressive Disorders of the Volitional Questionnaire-Chinese Version

Abstract

Objective: The purpose of the study was to introduce the development of Volitional Questionnaire-Chinese version and to examine the test-retest reliability of the Volitional Questionnaire-Chinese version for clients with depression in Taiwan.

Methods: The Volitional Questionnaire was translated into Mandarin via 2 stage methodology and tested on 46 clients who were diagnosed with depressive disorders. The clients were consisted of eight males and thirty-eight females. The average age of the clients was 50.50 years old. (SD=15.37). All subjects participated in purposeful activities arranged by the researcher, the volitional status of the clients was assessed. After ten to fifteen days, reevaluation was carried out by the same researcher in the same environment.

Results: The results of the study showed that test-retest reliability of the Volitional Questionnaire-Chinese version, ICC= .82. Kappa value of individual item of the Volitional Questionnaire-Chinese version was between .452 and .777.

Conclusion: The findings of the study indicated that the Volitional Questionnaire- Chinese version has good test-retest reliability for clients with depressive disorder. Test-retest reliability of individual item of the Volitional Questionnaire-Chinese version was between moderate and good. Other psychometric properties of the Volitional Questionnaire-Chinese version need to be examined in the future.

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.
