These subclassifications are useful in broadly establishing several attributes of particular instruments such as accuracy, cost, and general applicability to different applications.
This replication study adds to four studies that have examined psychometric attributes of the instrument and contributes to the process of translating the use of this instrument to the clinical setting.
Eight attributes of an instrument properties to be considered when evaluating a questionnaire assessment tool include: (1) its conceptual and measurement model, (2) validity, (3) reliability, (4) responsiveness, (5) interpretability, (6) respondent and administrative burden, (7) alternative forms and (8) cultural and language adaptations (translations).
These decisions surround the key attributes of the instrument and considerations of the population, sample size, respondent burden, method/delivery mode, time frame, data output, data management, psychometric properties, measurement bias and cost of administration [ 5].
A key attribute of such instruments is the attention to the primary purpose of care planning, i.e., to provide the user with information targeting specific medical, functional, and social problems that need to be addressed and further guidance through care planning protocols.
On the one hand, the physical attributes of each musical instrument color its sound with unique spectro-temporal features.
Research into the nature of musical timbre often focuses on the role of physical attributes of each musical instrument and how it colors the sound produced to give it its unique identity.
Desired attributes of the survey instrument included comprehensiveness, simplicity in execution, standardized oral administration, and ease of comprehension by respondents, independent of their sociopolitical, cultural, and geographic background.
The specific attributes of a PRO instrument will affect the way it is developed, tested, and incorporated into a study protocol to support conclusions of treatment benefit.
Response issues are a result of the interplay between the respondents' motivation and capacities, the interview setting and attributes of the measurement instrument [ 14, 17, 20, 22] and can arise during several stages of the response process, as presented in a model by Tourangeau [ 17].
