Performance Assessment of Self-Care Skills

Last Updated

Purpose

PASS is a performance-based, criterion-referenced, and client-centered observational tool. The purpose of the PASS is to have a holistic snapshot (person-task-environment) of the client’s ability to live independently and safely in the community by assessing performance on various ADLs and IADLs. Independence, adequacy, and safety are rated on four-point scales.

Key Descriptions

  • 26 tasks in four different domains (Chisholm, Toto, Raina, Holm, & Rogers, 2014):
    -Functional mobility (5)
    -Basic Activities of Daily Living (3)
    -Instrumental Activities of Daily Living - physical emphasis (4)
    -Instrumental Activities of Daily Living - cognitive emphasis (14)
  • 163 criterion-referenced sub tasks (Chisholm et al., 2014)

    Each subtask is rated for independence, safety, and adequacy on a scale from 0-3.
    A higher score indicates greater independence, safety, or adequacy.
    Independence scores:
    -Depend both on level of assistance needed and on frequency of prompts
    -Independence for task is the mean of the independence scores for each subtask
    Safety score:
    -Accounts for risks to client or to environment
    -Safety score for task is the lowest observed safety score for any subtask within that task
    Adequacy score:
    -Accounts for efficiency with which task is performed and quality of product
    -Adequacy score for task is the lowest observed adequacy score for any subtask within that task
  • Tasks are administered to client in a standardized way, including placement of objects and verbal instructions (Chisholm et al., 2014).
    -Client attempts to perform task, and therapist provides assistance only when needed
    -Least assistive prompts are used prior to more assistive prompts
    -Frequency of prompts and types of assistance are recorded to aid in intervention planning
  • Two versions of PASS exist – clinic version and home version; they are nearly identical except that home version uses client’s own materials for the tasks (Raina, Rogers, & Holm, 2006).
  • PASS assessment is flexible (Chisholm et al., 2014)
    -Therapist may administer only those tasks deemed relevant to client
    -Therapist may use PASS template to develop new PASS items

Construct Validity

Depression (Chisholm, 2005, Depression)

  • Cattell’s scree test determined that the PASS Independence data has a dominate construct meeting the criteria of unidimensionality for the Rasch Model

Individuals with Cognitive and/or Physical Disabilities: (Ferreira et al., 2020; n = 98, Portuguese version of PASS)

  • The majority of scores across all domains and constructs were significantly lower for individuals 80 years old or older than for younger individuals.
    • No significant differences were found for the FM task “stair use” (independence: p = 0.358, safety: p = 0.298, adequacy: p = 0.628), for the BADL independence tasks “oral hygiene” (p = 0.263) and “trimming toenails” (p = 0.191), and for the CIADL tasks “stovetop use” (independence: p = 0.247, adequacy: p = 0.268) and “use of sharp utensils (independence: p = 0.281, safety: p = 0.808) 
  • No significant differences were found between the performance of males and females on 20 of the 22 tasks for independence, safety, and adequacy.
    • The two exceptions were for independence, with males scoring higher than females for “bill paying by ATM” (p = 0.035) and “changing TV command batteries” (p = 0.052)

Content Validity

Data not available, but authors state:

“Content validity of the PASS is based on the OARS Multidimensional Functional Assessment Questionnaire: Activities of Daily Living (Pfeiffer 1975), the Comprehensive Assessment and Referral Evaluation (Gurland et al., 1977), the Physical Self-Maintenance and Instrumental Self-Maintenance Scale (Lawton et al., 1982), and the Functional Assessment Questionnaire (Pfeffer 1987). Construct validity of the unidimensionality of the Independence and Safety scales of the PASS was established using exploratory factor analysis (Chisholm 2005)” (Chisholm et al., 2014)
