Knowledge Gaps and Scan-Associated Distress Among Cancer Patients: A Cross-Sectional Study

Abstract

Background

Cancer, a leading global cause of death, often requires radiological imaging, which can trigger psychological distress, including depression, anxiety, and stress.

Purpose

This descriptive study evaluated psychological distress and knowledge of imaging among 120 cancer patients in India.

Methods

Using the Depression Anxiety Stress Scale-21 and a 15-item knowledge questionnaire, data were analyzed with descriptive and nonparametric statistics.

Findings

Nearly half of the participants (49.2%) had poor knowledge of imaging procedures, 30% reported depression, over 40% experienced anxiety, and 10% exhibited stress. Knowledge was negatively correlated with depression (rho = −0.276, p = .002), anxiety (rho = −0.267, p = .003), and stress (rho = −0.184, p = .044). Lower socioeconomic status and claustrophobia were associated with higher anxiety, whereas prior information reduced anxiety levels.

Discussion

The findings highlight the importance of educational interventions to bridge knowledge gaps, reduce distress, and enhance patient outcomes, emphasizing a multidisciplinary approach that integrates psychological and educational support.
