The Association between ADL Ability and Quality of Life among People with Advanced Cancer

الملخص EN

Background.

Occupational therapy and occupational science are founded on the theoretical core assumption that occupation and quality of life (QoL) are closely related.

However, such theoretical core assumptions must be supported through empirically based research.

Objective.

To investigate the association between QoL and occupation, here self-reported and observed ADL abilities as a part of occupation, among people with advanced cancer, including determining whether self-reported or observed ADL ability had the stronger association with QoL.

Methods.

The study was nested in a cross-sectional study.

The association between ADL ability and QoL among 108 people with advanced cancer was investigated using the ADL Interview (ADL-I), the Assessment of Motor and Process Skills (AMPS), and the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC-QLQ-C30).

Results and Conclusions.

Results showed that high observed ADL motor ability was associated with high QoL.

In contrast, observed ADL process ability and self-reported ADL ability were not significantly associated with QoL.

Oppositely expected, observed ADL ability had a stronger association with QoL than self-reported ADL ability.

Thereby, the study to some extent contributes knowledge confirming the theoretical core assumptions about the relation between occupation, here performance of ADL, and QoL.
