Effects of a Visual Interactive LINE Chatbot on Self-Management of EGFR-TKI Related Side Effects in Patients With Lung Cancer

August 10, 2026 updated by: National Taiwan University Hospital

A Randomized Controlled Trial to Evaluate the Effects of a Visual-Interactive LINE Chatbot on Self-Management of EGFR-TKI-Related Side Effects in Patients With Lung Cancer

This study aims to evaluate a visual interactive LINE chatbot designed to support self-management of treatment-related side effects among patients with advanced lung cancer receiving epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy.

Patients receiving EGFR-TKI treatment often experience long-term side effects that require ongoing self-management. In this randomized controlled trial, participants will be assigned to receive either usual care alone or usual care plus access to the LINE chatbot intervention, which provides visualized and interactive educational content for symptom monitoring and self-care.

The primary outcome of this study is self-management ability related to EGFR-TKI-associated side effects. Secondary outcomes include quality of life during treatment and overall satisfaction with the LINE chatbot intervention.

Detailed Description

The objective of this study is to evaluate a visual interactive LINE chatbot designed to support self-management of treatment-related side effects among patients with advanced lung cancer receiving epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy.

This study uses a randomized controlled trial design. Participants will be recruited from a medical center in northern Taiwan and randomly assigned to either an intervention group or a control group. The control group will receive standard education and routine clinical care, while the intervention group will receive standard care plus access to the visual interactive LINE chatbot intervention. The chatbot provides visualized and interactive educational content to support symptom monitoring and self-care during treatment.

Assessments will be conducted at baseline and at multiple follow-up time points after enrollment to evaluate self-management ability related to EGFR-TKI-associated side effects, quality of life during treatment, and overall satisfaction with the chatbot intervention.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: LINE Chatbot Intervention Group
Participants receive usual care plus access to a visual interactive LINE chatbot designed to support self-management of treatment-related side effects during EGFR-TKI therapy.
Behavioral: Visual-Interactive LINE Chatbot
Participants receive access to a visual-interactive LINE chatbot designed to support self-management of EGFR-TKI-related side effects. The chatbot provides interactive and visualized educational content, symptom monitoring guidance, and self-care recommendations throughout the treatment period, in addition to usual care.
No Intervention: usual care
Participants receive usual care, which consists of standard paper-based educational materials provided as part of routine clinical care, without access to the LINE chatbot.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Self-Management Ability（PAM-13）
Time Frame: at baseline and at 1, 3, and 6 months post-intervention

Self-management ability is measured using the Patient Activation Measure (PAM-13) developed by Hibbard et al. (2005).

The PAM-13 consists of 13 items assessing an individual's knowledge, skills, and confidence in managing their health or chronic condition.

Each item is rated on a 4-point Likert scale, and raw scores are transformed into a standardized score ranging from 0 to 100, with higher scores indicating greater self-management ability and willingness to engage in self-care.

The Chinese version of the PAM-13 has demonstrated good internal consistency, with a Cronbach's alpha of 0.835.
at baseline and at 1, 3, and 6 months post-intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Quality of Life Related to EGFR-TKI Treatment（FACT-EGFRI-18）
Time Frame: at baseline and at 1, 3, and 6 months post-intervention

Quality of life is assessed using the Functional Assessment of Cancer Therapy-Epidermal Growth Factor Receptor Inhibitor 18-item scale (FACT-EGFRI-18) developed by Wagner et al. (2013).

The FACT-EGFRI-18 consists of 18 items evaluating the impact of EGFR-TKI-related dermatologic toxicities on patients' physical, psychological, social, skin, nail, and hair-related well-being.

Items are rated on a 5-point Likert scale, with total scores ranging from 18 to 90.

Higher scores indicate greater symptom burden and poorer quality of life. The Chinese version of the FACT-EGFRI-18 has demonstrated good internal consistency, with Cronbach's alpha values ranging from 0.83 to 0.95.
at baseline and at 1, 3, and 6 months post-intervention
Overall User Satisfaction With the LINE Chatbot Intervention (CSQ-8)
Time Frame: At 3 months after the intervention

User satisfaction is measured using the Client Satisfaction Questionnaire-8 (CSQ-8) developed by Larsen et al. (1979).

The CSQ-8 consists of 8 items assessing overall satisfaction with healthcare or psychosocial interventions.

Each item is rated on a 4-point Likert scale, with total scores ranging from 8 to 32, where higher scores indicate greater satisfaction with the intervention.

The CSQ-8 has demonstrated high internal consistency, with reported Cronbach's alpha values ranging from 0.93 to 0.95.
At 3 months after the intervention
