The AMPS is an innovative observational assessment that is used to measure the
quality of a person's activities of daily living (ADL). The quality of the person's ADL
performance is assessed by rating the effort, efficiency, safety, and independence of
16 ADL motor and 20 ADL process skill items, while the person is doing chosen,
familiar, and life-relevant ADL tasks. There are more than 100 standardized ADL
tasks. The AMPS is ideal for occupational therapists who are looking for a valid and
reliable assessment of the quality of a person's ADL performance.
The 5-day training workshop provides critical information related to the theoretical
basis of the AMPS as well as experiential learning of administering and scoring AMPS
evaluations. Participants obtain valuable, hands-on information regarding occupation-
based assessment and intervention, as well as viewing and scoring videotaped and
live AMPS observations during the course. Rater calibration is required following the 5-
day course, potential AMPS raters must complete 10 live observations after the course
and submit this data for rater calibration. Rater calibration allows each rater's severity
to be determined and whether or not he or she is scoring the AMPS in a reliable
The AMPS is unique in several ways:
1. The ADL tasks that the person performs for the assessment are chosen by the
person, and are meaningful and relevant to his or her daily life and living situation. It
is believed that ADL task performance is maximized when an individual has the
opportunity to choose and enter into an activity that matches the individual's volitional
2. The AMPS provides occupational therapists with a powerful and sensitive tool
that can assist with treatment planning and documenting change.
3. The AMPS is an ideal assessment for managed care environments and other
settings where occupational therapists need to demonstrate the efficacy of their
interventions in a cost-effective and client-centred manner.
4. The AMPs requires no special equipment and can be administered in any relevant
setting within 30-40 minutes.
5. The measurement model used to develop the AMPS allows a therapist to
determine the ADL ability of the person, while taking into account the relative
challenge of each of the ADL tasks the person performed. As a result, people who
performed different ADL tasks can be directly compared.
6. The measurement model used to analyse the person's scores also allows us to
generate ADL ability measures that are adjusted to account for the severity of the
rater who rated the personâ€™s performance. As a result, a person's ability measures
are not biased by the particular rater who observed the performance.
7. The AMPS has been designed so that it can be administered to children over the
developmental age of 3 years, adolescents, adults, and older persons for whom there
is concern about ADL task performance. The diagnosis of the person or the reason for
the functional limitations does not matter.
8. The AMPS has been standardized internationally and cross-culturally on more
than 100,000 subjects.
The AMP's has the following limitations:
1. Participation in a 5 day training and calibration workshop, with follow-up testing
of 10 people after the course, is required to develop skill in the administration and
interpretation of the AMPS, and to complete the rater calibration process.
2. The AMPS is not suitable for evaluation of Children under the developmental age
of 2 years, or persons who have no need or who are unwilling to participate in simple
daily life tasks.
3. If the AMPS is to be used for documenting treatment efficacy, quality assurance,
or research, it must be computer-scored. This is necessary to compute overall ADL
motor ability and ADL process ability measures that have been adjusted to account for
(a) the challenge of the tasks the person performed, and (b) the leniency of the rater
who scored the person's performance. The computer-scoring software is included with
the AMPS training and calibration workshop materials.
4. The AMPS computer-scoring software is provided only to persons who participate
in AMPS training and calibration workshops.
