Nico Varela in Health & Wellness July 2025 • 5 min read.

"Discover how the Care Dependency Scale (CDS) is transforming oncology nursing by providing a reliable way to assess and address the holistic needs of cancer patients."

In the ever-evolving landscape of cancer care, healthcare professionals face the increasing challenge of addressing the diverse needs of patients undergoing treatment. As medical advancements extend lifespans and more individuals navigate the complexities of cancer, the focus shifts towards enhancing the overall quality of life for those affected. This paradigm shift necessitates innovative tools and approaches that enable healthcare providers to deliver holistic, patient-centered care.

One such tool making waves in oncology nursing is the Care Dependency Scale (CDS). Designed to measure a patient's level of dependence, the CDS goes beyond simply assessing physical limitations. It delves into the psychosocial aspects of care, providing nurses with a comprehensive understanding of the challenges patients face. By incorporating both physical and emotional dimensions, the CDS allows for more targeted and effective interventions, ensuring that patients receive the support they need to maintain their well-being throughout their cancer journey.

This article explores the significance of the Care Dependency Scale in oncology nursing, shedding light on its development, validation, and practical applications. We will delve into how the CDS empowers nurses to assess patient needs accurately, tailor care plans effectively, and ultimately improve the lives of individuals battling cancer. Understanding the CDS is not just about adopting a new tool; it's about embracing a philosophy of care that recognizes the multifaceted nature of the patient experience.

Unveiling the Care Dependency Scale: A Holistic Approach to Oncology Nursing

The Care Dependency Scale (CDS) stands out as a unique instrument designed to specifically measure patient dependence in nursing care. Unlike generic assessment tools, the CDS hones in on the nuances of dependence, providing a more accurate reflection of a patient's needs. Its psychometric properties have been rigorously tested across diverse populations, solidifying its reliability and validity as a measurement tool.

A recent study published in the Annals of Oncology sought to validate the CDS for use with cancer patients. Researchers M. Piredda, V. Biagioli, B. Brun, and colleagues conducted a cross-validation study involving 330 adult inpatients with cancer. The study, which took place in the oncology units of two hospitals in Rome, Italy, from June 2015 to February 2016, employed Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to assess the CDS's psychometric properties.

Exploratory Factor Analysis (EFA): A statistical method used to discover the underlying structure of a dataset by identifying the number of factors required to represent the relationships among a set of measured variables.
Confirmatory Factor Analysis (CFA): A statistical technique used to test a specific hypothesis or theory about the structure of a dataset by examining the extent to which the data fit the hypothesized model.
Mplus MLR Estimator: A robust statistical estimation method used to handle non-normal data and complex models, providing accurate parameter estimates and standard errors.
Psychometric Properties: The characteristics of a measurement instrument that indicate its reliability, validity, and overall quality, including its ability to consistently and accurately measure the intended construct.

The EFA initially revealed a two-factor model. However, item 5 demonstrated poor factor loading, prompting its removal to improve the scale's internal consistency. The refined 14-item solution underwent cross-validation through CFA, revealing the need for minor adjustments to enhance the model's fit. Ultimately, the revised model demonstrated good fit indices, confirming its validity and reliability for assessing care dependency in cancer patients. The two factors identified were labeled Physical care dependency (items 1-4, 6-9, 13, 14) and Psychosocial care dependency (items 7, 9-12, 15).

Empowering Nurses, Enhancing Patient Care

In conclusion, the Care Dependency Scale offers oncology nurses a valuable tool for providing comprehensive and holistic care. By accurately measuring both physical and psychosocial aspects of care dependency, the CDS enables nurses to tailor their interventions to meet the unique needs of each patient. This, in turn, leads to improved patient outcomes and a more positive experience throughout the cancer journey. Embracing the CDS is an investment in patient-centered care, empowering nurses to make a meaningful difference in the lives of those they serve.

Everything You Need To Know

What is the Care Dependency Scale (CDS), and how does it specifically apply to oncology nursing?

The Care Dependency Scale (CDS) is a specialized assessment tool used in oncology nursing to measure a patient's level of dependence, considering both physical and psychosocial needs. It helps nurses understand the holistic challenges patients face, enabling targeted and effective care interventions, ultimately enhancing the patient's well-being during their cancer journey. Unlike generic assessment tools, it focuses specifically on the nuances of dependence related to cancer care, making it particularly valuable in this context.

According to the research, what are the two primary factors identified within the Care Dependency Scale (CDS), and why is understanding these factors important?

The two primary factors identified within the Care Dependency Scale (CDS) are Physical care dependency and Psychosocial care dependency. Physical care dependency encompasses items that assess the patient's need for assistance with physical tasks and functions. Psychosocial care dependency includes items that evaluate the patient's emotional and psychological support requirements. Understanding these two factors allows nurses to create comprehensive care plans that address both the physical and emotional aspects of a patient's care needs.

Can you explain the roles of Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) in validating the Care Dependency Scale (CDS)?

Exploratory Factor Analysis (EFA) is a statistical method used to uncover the underlying structure of a dataset. In the context of validating the Care Dependency Scale (CDS), EFA helps identify the number of factors needed to represent the relationships among the measured variables, such as physical and psychosocial needs. Confirmatory Factor Analysis (CFA) is then used to test a specific hypothesis about the structure of the dataset, confirming how well the data fits the hypothesized model. Both EFA and CFA are crucial in ensuring the CDS accurately measures what it intends to measure.

What is the Mplus MLR Estimator, and why is it significant in the statistical validation of the Care Dependency Scale (CDS)?

The Mplus MLR Estimator is a robust statistical estimation method designed to handle non-normal data and complex models. When validating the Care Dependency Scale (CDS), it provides accurate parameter estimates and standard errors, even when the data does not follow a normal distribution. This is important because healthcare data, including patient-reported outcomes, often deviate from normality. The Mplus MLR Estimator ensures the statistical analyses are reliable, leading to valid conclusions about the CDS's performance.

What are 'psychometric properties,' and why is their assessment crucial for the Care Dependency Scale (CDS) in oncology nursing?

Psychometric properties refer to the characteristics of a measurement instrument that indicate its reliability, validity, and overall quality. For the Care Dependency Scale (CDS), assessing psychometric properties involves evaluating its ability to consistently and accurately measure the intended constructs—physical and psychosocial care dependency. A rigorous assessment of these properties, including reliability coefficients and validity indices, ensures that the CDS is a trustworthy tool for assessing patient needs and guiding nursing interventions, contributing to improved patient outcomes and quality of care.
