3.1. Design
A comparison was made between the three stress management methods including blended intervention (face-to-face sessions along with the use of smartphone applications), intervention solely based on the application, and intervention by face-to-face sessions via the educational-psychological approach using a quasi-experimental design together with consistent pretests and posttest.
In the present study, we applied the Aramgar stress management application, designed for Persian-speaking users. The stress management application Aramgar was designed based on emotion-focused coping according to the mindfulness-based stress reduction (MSBR). After installing and running Aramgar, users were asked to provide some information within the sign-up process.
First, users needed to provide their personal information such as the national ID number, sex, and age for the application to sign up. Second, during the sign-up and consent-gaining procedure, Aramgar administered the initial surveys that could be completed in multiple sittings requiring the user to spend 5 - 10 minutes on average to complete them. After completing the survey, a username and a password were activated. Finally, the suitable time to send messages and notifications were asked from users, which ranged from 9 to 11 in the morning, 13 to 16 in the afternoon, 17 to 19 in the evening, and 21 to 23 at night. After registration, a short video clip was displayed on Aramgar to introduce the stress reduction content adopted from the MSBR and the way the application was accessible.
In the first stage and layer of the application, in order to inform users, the primary training was performed in the course of a written text process. In this context, various contents were presented concerning stress, the process of stress formation, sources of stress, the physiology of stress comprising the automatic nervous systems, hormones and immune system, stress and illnesses, symptoms of stress, i.e. physical and psychological ones, stress management methods such as adaptation, controlling and stopping thoughts, modification of type A personality, time management, reading skills, preparation for exams, interpersonal relationships, nutrition, and sports.
In this section, numerous questionnaires were administered to measure self-assessment, such as the perceived stress scale (PSS-14), Weekly Stress Inventory, the Holmes and Rahe stress scale, physiological measures of stress, student stress survey (SSS), the occupational stress scale, and stress coping strategies questionnaire so that the users could measure themselves according to their needs for self-assessment and self-measurement. It should be noted that in the end, the feedback of the assessment regarding the level of stress perception was provided to users.
In the second stage and layer of application,
Aramgar offered notifications to deliver a short set of questions to the users on a daily basis to assess their stress levels in actual time so that they could self-monitor their behaviors. The calculation of perceived stress scores was through asking three questions on stressful events and worry episodes (
34). Participants were asked to indicate the duration of their worries: “less than 5 minutes, 5 - 30 minutes, 30 - 60 minutes, and more than 60 minutes.” Afterward, they were asked to give the extent of the worry episode(s) on a scale ranging from “slightly intense” to “very intense” and “end points ranging from 0 to 10” (10 positive and negative affect schedule (PANAS-SF) (
35) ranging from “slightly positive or negative” to “extremely positive or negative”, and the visual analogue scale (VAS) (
36), which consisted of a small, unmarked 100 mm ruler with endpoints labeled as “none” and “as bad as it could be”). Participants should say how they felt stressed on the small ruler. The daily stress perception of the users was calculated using the sum of the scores of worry episodes scale, positive and negative affect schedule, and visual analogue scale. In the third stage and layer, based on the protocols of reducing stress of emergency response, the intervening notifications were delivered daily for 20 days in the form of audio, video, and text contents with approximately 40 characters according to the users’ stress level (severe, moderate, or low).
The messages appeared in different formats. Some of them were in the form of educational videos of muscle relaxation such as tensing and relaxation of muscle groups, e.g., the muscles of legs, abdomen, chest, arms, and face, besides taking deep breath. The audio formats were on mindfulness skills such as mindfulness in daily living, three-minute mindful practice, mindful eating, managing thoughts, mindful breathing, body scan, walking meditation, mindful movement, mindfulness and values, kindness practice, and maintaining a regular practice. The other part of audio messages was related to single, specific sounds, e.g., the sound of nature such as waterfalls, river flow, and the wind and bird songs.
After diagnosing a severe level of stress in the users, an educational video on muscle relaxation and deep breathing was delivered to them to exercise and then, some text messages concerning mindful practices were given to them. In the end, some relaxing audio messages with natural sounds were played. Therefore, a specific timetable was designed for sending messages based on the users’ stress level with contents prepared and developed under the supervision of a psychology specialist. Finally, the timetable was transferred to the programmers and developers of the application to regulate sending messages.
To put into use the results of the present study, following an introduction and explanation of the goals to the authorities of a counseling center at Tehran University of Medical Sciences and in collaboration with them, a workshop on stress management skills was announced for students who needed such skills or were conscious of their stress. The criteria for the inclusion of students in the workshop were as follows: studying or passing the last year, being evaluated and clarified in the last month for stress level through PSS-14, having no signs of psychiatric disorders (no referral to psychiatric centers in the last month), having experienced no psychological interventions in the last month; having a smartphone with Android platform, and being interested in participation.
Therefore, a group of 68 students was formed. Then, during a meeting, the objectives of the study were explained to them and their consent for cooperation with the workshop was obtained. Afterwards, they were randomly assigned into three groups: Aramgar mobile application alone (Group 1, N = 20), blended intervention, i.e., a combination of face-to-face sessions and smartphone application Aramgar for providing automated reminders and motivational messages based on the stress level of participants (Group 2, N = 28) and, face-to-face sessions (Group 3, N = 20).
All the three groups took the DASS-21 test. Following a meeting with the students of Group 1 and introduction of the study and its goals to them, they were asked to install the
Aramgar application on their phones and do the exercises according to the notifications for 20 days. For Group 2, subsequent to the introduction of the study and its objectives, the students were asked to participate in face-to-face sessions and use the
Aramgar application. Interventions in this group were made in six weeks during which, the students were invited to participate in the workshop sessions on Sundays and Tuesdays every week. The content of the workshop was based on the mindfulness-based stress reduction (MBSR) program developed by Dr. Jon Kabat-Zinn (
37). It is used to increase skills such as body scan, sitting meditation, movement exercises, and mindfulness practice in daily life. At the end of the second session, the project director introduced the
Aramgar application to the applicants and asked them to install it on their phones and do the exercises for 20 days in accordance with the notifications given. Finally, for Group 3, the stress management sessions were held at the counseling center on Mondays and Wednesdays every week for six weeks.
