Brief Summary

This study is a randomized, controlled experimental trial with a pretest-posttest design, conducted to evaluate the effects of Pecha Kucha-based education on self-efficacy, symptom level, and activities of daily living in individuals diagnosed with chronic obstructive pulmonary disease (COPD) receiving noninvasive mechanical ventilation support. The study will include two groups, and intergroup differences will be evaluated:

1. 1.Control group
2. 2.Intervention group

Conditions

Chronic Obstructive Pulmonary Disease (COPD); Activities of Daily Living

Keywords

self-efficacy; symptom severity; activities of daily living; Chronic Obstructive Pulmonary Disease; Pecha Kucha

Outcome Measures

Primary Outcomes (3)

• Self Efficacy

  The COPD Self-Efficacy Scale is a 5-point Likert-type instrument consisting of 34 items and five subscales that assess patients' confidence in managing or avoiding dyspnea during specific activities. The five subscales are negative affect, emotional arousal, physical exertion, weather/environmental factors, and behavioral risk factors. The negative affect subscale measures confidence in managing dyspnea in stressful situations. The emotional arousal subscale assesses confidence in coping with dyspnea during emotional distress such as anger, fear, and life-related stress. The physical exertion subscale evaluates confidence in managing dyspnea during situations that may provoke breathlessness, such as rapid stair climbing or cold weather exposure. The behavioral risk factors subscale measures behaviors related to non-adherence to diet and treatment and dyspnea-related behaviors. Higher scores indicate greater confidence in managing or avoiding dyspnea. Total scores range from 34 to 170.

  Participants in the intervention group will receive baseline assessment, followed by Pecha Kucha-based training, with follow-up assessments at 1 and 3 months. The control group will be assessed at the same time points without education.

• Symptom Level

  The COPD Assessment Test (CAT) is an instrument used to assess the impact of COPD symptoms, including dyspnea, cough, sputum production, fatigue, and activity limitations, on daily life and overall health status. The CAT consists of 8 items and is simple and quick to administer. Each item is scored on a 5-point scale, with total scores ranging from 0 to 40. Higher scores indicate a greater impact of COPD symptoms and increased severity of dyspnea. Scores are categorized as low (0-10), moderate (11-20), high (21-30), and very high impact (31-40). The CAT is a reliable and valid tool widely used in clinical practice.

  Baseline, 1 month, and 3 months. Participants in the Pecha Kucha education group will receive Pecha Kucha-based training after the baseline assessment and will be evaluated at 1 and 3 month follow-ups. The control group will be evaluated at the same time

• Daily Living Activities

  The London Chest Activity of Daily Living Scale is a simple questionnaire developed to assess dyspnea related to daily living activities in patients with COPD. It consists of 15 items across four domains: personal care (4 items: drying, dressing the upper body, putting on shoes/socks, washing hair), domestic activities (6 items: making the bed, changing sheets, washing windows/curtains, cleaning/dusting, washing dishes, vacuuming), physical activity (2 items: climbing stairs, bending), and leisure activities (3 items: walking indoors, going out socially, talking). The maximum possible score is 75. Higher scores indicate greater limitation in performing daily activities, whereas lower scores reflect higher activity levels.

  Participants in the intervention group will receive baseline assessment, followed by Pecha Kucha-based training, with follow-up assessments at 1 and 3 months. The control group will be assessed at the same time points without education.

Study Arms (2)

Control Group

NO INTERVENTION

At baseline, pre-test data will be collected using the study data collection instruments. Patients will be asked to record their weekly duration of noninvasive mechanical ventilator use using the Noninvasive Mechanical Ventilator Use Monitoring Form throughout a three-month follow-up period. This group will receive the standard education and follow-up program routinely provided in the hospital, which includes physician-led training on prescribed ventilator usage duration and proper application of the device, along with monthly follow-up visits. No additional education based on the Pecha Kucha technique will be provided. Data collection instruments will be re-administered in the control group at the interim assessment conducted one month after baseline and at the final assessment conducted three months after baseline.

Pecha Kucha Education Group

EXPERIMENTAL

In the intervention group, baseline (pre-test) data will be collected prior to the educational intervention. Participants will be asked to complete the Noninvasive Mechanical Ventilator Use Monitoring Form according to their ventilator use. Immediately after baseline data collection, education will be provided using the Pecha Kucha presentation technique. The educational content will include symptom control, energy conservation strategies for sleep and daily activities, definition and benefits of noninvasive mechanical ventilation, potential complications, mask types, ventilator components, humidification, proper application, and cleaning and maintenance of the device. After the Pecha Kucha-based education, the training video will be sent weekly to participants' mobile phones for three months. Data collection instruments will be re-administered at one month (interim assessment) and three months (final assessment) after baseline.

Other: Intervention Group

Interventions

Intervention Group OTHER

Participants in the intervention group will receive education on mechanical ventilator support using the Pecha Kucha presentation technique. The educational content will include symptom control, energy conservation strategies for sleep and daily activities, the definition and benefits of noninvasive mechanical ventilation, potential complications, mask types, ventilator components, humidification in noninvasive mechanical ventilation, proper application of the ventilator, and cleaning and maintenance procedures. The presentation will consist of 20 slides and will last approximately 6-7 minutes. The training video will be sent weekly to the intervention group for a period of three months.
