What is Development of an 18-Item Measure of Symptom Burden in Patients With Glaucoma From the Collaborative Initial Glaucoma Treatment Study’s Symptom and Health Problem Checklist about?

## Importance: Administration of a brief questionnaire to evaluate glaucoma symptoms would lend useful information for patient care. ## Objectives: To develop a shortened glaucoma symptom measure based on the collaborative initial glaucoma treatment study (cigts) symptom and health problem checklist (shpc) and evaluate its psychometric properties. ## Design, setting, and participants: This measure development study evaluated the factor structure of the 43-item shpc that was obtained from cigts participants at baseline and every 6 months thereafter. these 607 participants were enrolled at 14 clinical centers in the united states and had newly diagnosed open-angle glaucoma. their mean deviation (sd) from visual field testing was −5.5 (4.3) db. data were collected from october 1993 through april 1997. ## Main outcomes and measures: The factor structure of the shpc, confirmatory factor analysis of the resulting 18-item questionnaire (shpc-18), the reliability of the shpc-18, and associations of the 2 symptom subscales (local eye and visual function) of the shpc-18 with visual field severity and 25-item national eye institute visual function questionnaire (nei-vfq25) subscales. ## Resul
