Klein-Bell Activities of Daily Living Scale (K-B Scale)

Download Clinical Summary PDF

Tool Description

  • generic instrument that can be used with persons with or without disability.
  • developed to measure basic activities of daily living (ADL) independence in both adults and children.

Items are divided into 6 sub-dimensions:
1) Mobility
2) Emergency Communication
3) Dressing
4) Elimination
5) Bathing/Hygiene
6) Eating.

  • The majority of items measure ADLs and others measure body function (bladder/bowel emptying and incontinence, chewing/swallowing food and liquids, verbalizing telephone messages).

ICF Domain:

Activity – Subcategory: Self-Care.

Number of Items:

170

Brief Instructions for Administration & Scoring

Administration:

  • clinician-administered interview
  • measures degree of patient independence
  • Administration of the scale takes from 1-3 hours.

Equipment: items typically used in basic activities of daily living (ex. toilet, bed, etc.)

Scoring:

  • Task weights of 1, 2, or 3 are assigned to each task.
  • In developing the weights, four factors were considered, including: importance to health, difficulty for non-disabled persons, time required to perform the task, and the burden of care-giving.
  • Items are summed (each task is multiplied by its weight)
  • Overall independence scores range from 0 to 313 (0%-100%).

Interpretability

MCID: not established
SEM: not established
MDC: not established

  • Higher scores indicate greater independence.
  • No normative data has been established for the SCI population at this time.

Languages:

English.

Training Required:

None formally required.

Unable to locate the scale for use.

Clinical Considerations

  • The K-B Scale divides each activity into its essential components to get a measure of basic ADL. This is advantageous over other known ADL scales as it makes it possible to detect problematic items within activities and thus helps to better identify rehabilitation treatment.
  • The authors suggest using the scale as a method to generate discussion about goals they wish to achieve.
  • The scale was not designed specifically for SCI subjects; therefore, items included in the scale may not be important for SCI populations.

Measurement Property Summary

# of studies reporting psychometric properties: 2

Reliability:

No values were reported for the reliability of the Klein-Bell Scale for the SCI population.

Validity:

  • Correlation of the Klein-Bell scale is High with:
    • the Jebsen-Taylor total score (Spearman’s r=-0.635)
    • the Jebsen-Taylor Test- dressing subscale (Spearman’s r=-0.69),
    • the ASIA Upper Extremity Motor Score (UEMS) (Correlation = 0.63)
  • and Moderate with:
    • the Jebsen Taylor Test – Bathing/Hygiene subscale (Spearman’s r=-0.57)
    • the Jebsen Taylor Test – Eating subscale (Spearman’s r=-0.45).

Responsiveness:

No values were reported for the responsiveness of the Klein-Bell Scale for the SCI population.

Floor/ceiling effect:

No values were reported for the presence of floor/ceiling effects in the K-B Scale for the SCI population.
