Mild cognitive impairment, common in cancer survivors, directly correlates with reduced engagement in everyday activities. This human factors research insight is drawn from a 2014 study published in The Open Journal of Occupational Therapy. Using Quantitative, non-experimental, cross-sectional design with qualitative data collection. with 35 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for populations affected by chronic illness or treatment, integrate cognitive function assessments and support into the design process to ensure products and services are usable and promote well-being.

Cognitive Impairment in Cancer Survivors Significantly Reduces Daily Life Participation

Mild cognitive impairment, common in cancer survivors, directly correlates with reduced engagement in everyday activities.

01

Key Findings

  • 01A significant percentage of cancer survivors exhibit mild cognitive impairment (average MoCA score of 25).
  • 02Cancer survivors demonstrate suboptimal reintegration into daily activities (average RNLI-P score of 9.64).
  • 03The majority of surveyed participants (17/21) reported cognitive changes related to cancer and its treatment.
  • 04Reported cognitive changes led to decreased participation, increased selectivity in activities, or a perceived need to balance activities.

Application

Design takeaway

When designing for populations affected by chronic illness or treatment, integrate cognitive function assessments and support into the design process to ensure products and services are usable and promote well-being.

How to apply

When designing any product or service intended for use by individuals who may have experienced significant medical events or treatments, consider conducting user research that includes assessments of cognitive function and its impact on task performance.

Project actions

  • 01If your design project involves a user group that might experience cognitive changes (e.g., due to age, illness, or medication), consider how to make your design easier to understand and use.
  • 02Think about incorporating features that help users remember things or break down complex tasks.
03

Method & Evidence

AimTo investigate the relationship between cognitive status and participation in daily activities among cancer survivors.
MethodQuantitative, non-experimental, cross-sectional design with qualitative data collection.
ProcedureCancer survivors were assessed for cognitive status using the Montreal Cognitive Assessment (MoCA) and for their reintegration into daily life using the Reintegration to Normal Index-Postal Version (RNLI-P). A supplemental questionnaire was used to gather participants' perspectives on their cognitive changes and functional performance.
Sample35 participants
ContextHealthcare and rehabilitation for cancer survivors.

Variables

IVCognitive status (e.g., presence and severity of impairment).
DVLife participation (measured by reintegration into daily activities).
CVAge, type of cancer, treatment received, time since diagnosis.
04

Strengths & Limitations

Strengths

  • +Combines quantitative measures of cognition and participation with qualitative insights into user experience.
  • +Highlights a significant, often overlooked, factor impacting daily life for a specific patient group.

Limitations

The findings are specific to cancer survivors and may not generalize to all populations experiencing cognitive impairment. The study's cross-sectional nature limits the ability to track changes over time.

Reliability & validity

Reliability of MoCA and RNLI-P are established. Validity of self-reported cognitive changes and participation levels may be a concern. The cross-sectional design limits internal validity regarding causality.

Think critically

How might the design of digital interfaces be adapted to better support individuals with mild cognitive impairment, and what are the ethical considerations in such adaptations?

05

Design Principles

"Design for cognitive accessibility by simplifying interfaces, providing clear and concise information, and offering memory support mechanisms."

Understanding the cognitive impact of cancer and its treatment is crucial for designing supportive environments and assistive technologies. This insight highlights the need to consider cognitive function as a primary human factor in the design of products and services for this population, moving beyond purely physical or functional considerations.

06

What This Means for Your Design

Cancer survivors often find it harder to do everyday things because their thinking skills are affected by their illness or treatment, leading them to do less or change how they do things.

Paragraph starter

Research indicates that cognitive impairment, prevalent in populations such as cancer survivors, significantly impacts their ability to participate in daily activities. For instance, studies have shown that mild cognitive impairment can lead to reduced engagement in instrumental activities of daily living, necessitating design considerations that simplify tasks, provide clear instructions, and offer memory support to ensure product usability and user well-being.
