Brief Summary

The investigators have developed a mobile application named 'DangDang Care' (which conveys the meaning of managing diabetes confidently and consistently through psychological care) designed to provide psychological support and enhance diabetes self-management for people with type 2 diabetes experiencing depressive symptoms. The application incorporates a behavioral activation program. Subsequently, the investigators conducted a 12-week randomized controlled trial, enrolling individuals with type 2 diabetes and mild-to-moderate depression, with the assistance of public health centers. The trial aimed to assess the effectiveness and feasibility of the application in promoting consistent diabetes management through added psychological care.

Conditions

Diabetes Mellitus, Type 2; Depression

Outcome Measures

Primary Outcomes (8)

• Changes in Patient Health Questionnaire-9 (PHQ-9) scores

  The PHQ-9 is a 9-item self-report scale developed to assess the presence and severity of depression within the past 2 weeks. It was adapted for use with Korean participants. Respondents rate how often they have been bothered by each problem on a 4-point Likert scale ranging from 0 to 3. The total score ranges from 0 to 27, with higher scores indicating more severe depressive symptoms, and a cutoff score of 10 is used.

  By week 12

• Changes in Generalized Anxiety Disorder-7 (GAD-7) scores

  The GAD-7 is a brief self-report scale that assesses generalized anxiety disorder, comprising 7 items. Respondents rate the frequency of experiencing symptoms related to generalized anxiety disorder over the past 2 weeks using a 4-point Likert scale ranging from 0 to 3. Total scores range from 0 to 21, with higher scores indicating more severe anxiety. In this study, we used the Korean version of the GAD-7, accessible on the Patient Health Questionnaire website.

  By week 12

• Changes in Korean version of the Perceived Stress Scale (K-PSS) scores

  The Perceived Stress Scale (PSS), originally developed in 1983, was translated into Korean in 2010 and 2012. The K-PSS consists of 10 items, and respondents rate their responses on a 5-point Likert scale ranging from 0 to 4. The total score ranges from 0 to 40, with higher scores indicating higher perceived stress levels.

  By week 12

• Changes in Brief Diabetes Distress Screening Instrument (DDS-2) scores

  The DDS-2 is a brief version of the Diabetes Distress Scale, developed in 2008, and was translated into Korean in 2020. It consists of 2 items, and each item assesses the emotional burden of diabetes and the stress of diabetes management and treatment on a 6-point Likert scale ranging from 1 to 6. The total score ranges from 2 to 12, with higher scores indicating higher levels of diabetes-related stress.

  By week 12

• Changes in European Quality of Life-5 Dimensions 3 Level (EQ-5D-3L) index

  The EQ-5D-3L is a tool developed by the Euro Quality of Life Group to assess health-related quality of life. It comprises a descriptive system with five domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Respondents rate their current health state within each domain using three levels. The evaluative system included the EQ-5D-3L index. We employed the EQ-5D-3L index to calculate utility values for health states and evaluate the overall quality of life.

  By week 12

• Changes in Diabetes Self-Efficacy Scale (DSES) scores

  The DSES, originally developed by the Stanford Patient Education Research Center in 2009, was used in its Korean version translated by Young Sun Yeom in her thesis in 2010. It comprises 8 items, and respondents rate their level of confidence in successfully performing self-care behaviors on a 10-point Likert scale ranging from 1 to 10. Higher scores indicate a higher level of self-efficacy in managing diabetes.

  By week 12

• Changes in Diabetes Care Profile-Social Support Scale (DCP-SSS) scores

  The Diabetes Care Profile (DCP), developed in 1996, measures psychosocial factors and diabetes treatment. For this study, only the instrumental and emotional support subscales were utilized, and they were translated into Korean in 2007. The scale was modified to fit the study's purpose, resulting in a total of 9 items, excluding 3 items not relevant to the study. Each item was answered on a 5-point Likert scale from 1 to 5, with higher scores indicating higher perceived social support.

  By week 12

• Changes in Diabetes Self-Management Behaviors for Older Koreans (DSMB-O) scores

  The DSMB-O was developed in 2016 and is based on the self-management standards proposed by the American Association of Diabetes Educators, considering the characteristics of older adults with type 2 diabetes in Korea. The scale consists of a total of 14 questions, with 9 questions answered on a 4-point Likert scale from 0 to 3, and 5 dichotomous questions. The total score ranges from 0 to 30, with higher scores indicating higher levels of diabetes self-care behaviors.

  By week 12

Secondary Outcomes (3)

• Changes in glycated hemoglobin (%)

  By week 12

• Changes in fasting plasma glucose levels (mg/dL)

  By week 12

• Change in lipid profiles, including total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (mg/dL)

  By week 12

Other Outcomes (8)

• Persistent changes in Patient Health Questionnaire-9 (PHQ-9) scores

  By week 16

• Persistent changes in Generalized Anxiety Disorder-7 (GAD-7) scores

  By week 16

• Persistent changes in Korean version of the Perceived Stress Scale (K-PSS) scores

  By week 16
