OBJECTIVES: To develop, validate, and evaluate the readability, quality, and user acceptability of multilingual patient education materials — a structured booklet and a demonstrative video — for patients with Chronic Obstructive Pulmonary Disease (COPD), aimed at improving disease knowledge and inhaler technique across diverse literacy levels.
METHODS: Materials were developed using primary, secondary, and tertiary literature with expert clinical input from pulmonologists, pharmacists, physiotherapists, and dieticians. The booklet covered COPD pathophysiology, inhaler technique, lifestyle modifications, pranayama, pacing, relaxed positions, preventive measures, and self-monitoring action plans; the video demonstrated correct inhaler and nebulizer use. Content validity was assessed by a ten-member expert panel using Item-level and Scale-level Content Validity Index (I-CVI, S-CVI). Booklet readability was evaluated via Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL), and material quality via PEMAT-P and PEMAT-A/V. All materials were translated into Kannada and Malayalam using certified forward-backward translation. A quasi-experimental study enrolled 36 COPD inpatients (mean age 64.44 ± 10.0 years; 75% male) over six months. Knowledge questionnaire reliability was assessed by Intraclass Correlation Coefficient (ICC) using test-retest method; pre- and post-intervention scores were compared using paired t-test (SPSS v29). Acceptability was evaluated through a structured feedback questionnaire.
RESULTS: I-CVI and S-CVI/Ave scores of ≥0.8 confirmed strong content validity. The booklet achieved an FRE of 68.5 and FKGL of 6.6, indicating suitability for average adult literacy. All language versions scored 100% on PEMAT assessments. ICC values of 0.8-0.9 confirmed good-to-excellent questionnaire reliability. Post-intervention knowledge scores improved significantly across all language groups (p < 0.05). User feedback confirmed high acceptability, with materials rated as easy to understand, appropriate, and informative.
CONCLUSIONS: The multilingual COPD patient education booklet and video demonstrated strong validity, readability, quality, and acceptability. Significant knowledge improvement across language groups supports their effectiveness in diverse, low-to-middle literacy populations and recommends broad adoption in pulmonary care settings.
