Examines consumers’ subjective satisfaction with achievements in a variety of functional areas. Consumers are asked to characterize aspects of functioning, temperament, lifestyle, and views of a particular assistive device.

Clinical Considerations

  • The ATD-PA encourages user participation in the process of developing and setting goals and helps the consumer to better understand her or his own needs and interests. The ATD-PA is useful when a person has a complicated case and is a good tool for assessing a client’s ‘story’ with assistive technology.
  • Together with functional data, the ATD-PA has the potential to contribute to the formulation of consumer-directed needs and goals for rehabilitation. For persons with new spinal cord injury who indicate a poor history with assistive technology use, the ATD-PA can be a measure to identify obstacles to AT use early on in the course of rehabilitation.
  • The ATD-PA has been shown to be a reliable measure and to have adequate content and criterion-related validity in the SCI population.

Environmental Factors

Administration

  • Person-reported but can be applied through interview techniques.
  • Domain one contains 53 items. It is designed to be administered per individual across several time points. It is divided into four sections. Section A (items 1-9) asks respondents to rate their current capabilities in nine functional areas according to a five-point scale (1 = poor to 5 = excellent). All items in Sections B and C comprise the QOL subset. Each item is rated on a five-point scale (Section B: 1 = not satisfied; 5 = very satisfied; Section C: 1 = strongly disagree; 5 = strongly agree). Section D contains 33 statements about temperament and psychosocial support. Patients check those which apply to them.
  • Domain two is designed to be administered for each assistive technology device used across several time points. It consists of 10 items related to the expected benefit from a device. Patients rate each item on a five-point scale based on how much the statement applies to them (1 = does not apply to me; 5 = definitely applies to me).
  • In some spinal cord injury research publications, only domain two is used.

Interpretability

  • Scores from the quality of life section provide information regarding the consumer’s subjective quality of life.
  • Higher scores are indicative of better quality of life.
  • No meaningful cut-points or normative data have been established for the SCI population.

MCID: not established for SCI
SEM: not established for SCI
MDC: not established for SCI

Typical Values

Mean Scores (Person Domain Sections B & C only): 1.75-4.10

(Scherer & Cushman 2001; n=20; 10 males, 10 females; 13 paraplegia, 7 tetraplegia; complete and incomplete; acute SCI)

Reliability

Internal consistency of the ATD-PA was reported to be High (Cronbach’s α = 0.80).

(Scherer & Cushman 2001; n=20; 10 males, 10 females; 13 paraplegia, 7 tetraplegia; complete and incomplete; acute SCI)

Validity

Correlation of the ATD-PA Quality of Life subscale was High with:

  • The Brief Symptom Inventory (Spearman’s ρ = -0.71)
  • The Satisfaction with Life Scale (Spearman’s ρ = 0.89)

(Scherer & Cushman 2001; n=20; 10 males, 10 females; 13 paraplegia, 7 tetraplegia; complete and incomplete; acute SCI)

Responsiveness

No values were reported for responsiveness of the ATD-PA for the SCI population.

Floor/Ceiling Effect

No values were reported for the presence of floor/ceiling effects in the ATD-PA for the SCI population.
