Caregiver Quality of Life Index–Cancer [CQOLC-35]

Description

The Caregiver Quality of Life Index–Cancer (CQOLC-35) is a psychometric instrument designed to assess the quality of life of individuals caring for patients with cancer.

The scale consists of 35 items and examines the ways in which caregiving may affect different aspects of the caregiver’s everyday life, including psychological, physical, social, and practical functioning.

Purpose

The primary purpose of the CQOLC-35 is to systematically assess the impact of cancer caregiving on the well-being and functioning of caregivers.

Its use may help:

• identify psychological and physical burden,
• detect factors associated with better or poorer quality of life,
• assess support needs,
• guide the development of appropriate caregiver interventions.

Dimensions

The scale examines several aspects of the caregiving experience, including:

• Emotional well-being, including feelings of anxiety, sadness, and psychological strain.
• Physical health and energy, with emphasis on the physical demands of caregiving.
• Social relationships and support from family and the broader social environment.
• Financial impact, including burdens related to the cost and demands of caregiving.

Data Analysis and Use

CQOLC-35 data may be used to provide an overall picture of caregivers’ quality of life and to investigate factors associated with caregiver burden.

Statistical analysis may include:

• reliability analysis, using Cronbach’s alpha,
• factor analysis, to examine or confirm the structure of the scale,
• correlation analysis, to investigate relationships between quality of life and variables such as caregiving intensity or social support,
• comparisons between different caregiver groups.

The results may be used in both research and clinical settings.

Reliability and Validity

Psychometric evaluation of the CQOLC-35 includes examination of internal consistency, factor structure, and validity.

Cross-validation in different populations may help assess the generalizability of findings and the suitability of the scale across different cultural or clinical contexts.

The provided material does not report specific numerical reliability or validity coefficients; therefore, precise values should not be attributed without additional supporting evidence.

Applications

The CQOLC-35 may be used in oncology centers, hospitals, psychosocial support services, and research programs focusing on cancer caregiving.

It may help identify caregivers with increased support needs, monitor caregiver burden, and evaluate the effectiveness of supportive interventions.
