Abstract
Objectives: This study developed and validated the psychometric properties of an inventory for assessing distress of low anterior resection syndrome (LARS) in patients with rectal cancer.Methods: In this cross-sectional validated study, patients with LARS was conducted to develop a Symptom Distress Inventory of Low Anterior Resection Syndrome (SDI-LARS) by phases with create a draft of inventory by basis on a qualitative study and a literature review, assessing the content validity by colorectal surgical healthcare professionals, face validity by patients with LARS, construct validity by exploratory factor analysis with principle component analysis, criterion-related validity with LARS score by receiver operating characteristic curve analysis, reliability and test-retest reliability.Results: The SDI-LARS comprises 20 items. Psychometric evaluation well did by the content and face validity presented. By principle component analysis, the overall explained variance was excellent to categories the three domains of daily activity, emotion status and social functioning. Receiver operating characteristic curve analysis supported to identify patients with distress of LARS on a good sensitivity and specificity. Higher score indicated severer distress of low anterior resection syndrome. The cutoff score of the instrument was 19.5. And the cutoff score of its each domain were 6.5, 3.5 and 8.5, respectively. High internal consistent reliability, reliability, and test–retest reliability were noted.Implications for Nursing Practice: The SDI-LARS is a reliable and valid instrument for assessing symptom distress of LARS, which can be applied for screening and healthcare professionals can proactively identify patients with aforementioned distress and plan tailored individualized care. © 2024, The Authors.
