title: 自然接触对青少年手机依赖的影响：压力感知的作用

description: [Research on Dataset 1]1. Participants 700 paper questionnaires were distributed to junior high school students in a middle school in central China. After excluding invalid questionnaires such as regular responses, 651 valid questionnaires were finally collected, with a response rate of 93%. Among them, there were 344 male students and 307 female students, with an average age of 12.70 years (SD=0.69). 2. Research tools The natural contact questionnaire uses the items used by Xu and Jiang (2022). The questionnaire consists of 3 questions and is scored on a 5-point scale, with higher scores indicating higher levels of natural contact. In this study, the Cronbach's alpha coefficient of the questionnaire was 0.76. The Adolescent Mobile Phone Dependence Questionnaire was developed by Tao Shuman et al. (2013). The scale consists of 13 items and is composed of three dimensions: withdrawal, physical and mental impact, and craving. It uses a 5-point scoring system, with higher scores indicating higher levels of dependence on mobile phones. In this study, the overall Cronbach's alpha coefficient of the questionnaire was 0.90. The Chinese version of the stress perception scale was revised by Yang Tingzhong (2003) based on Cohen's stress perception scale. The scale consists of 14 items, which can be divided into two dimensions: tension and loss of control. It is scored on a 5-point scale, with higher scores indicating higher levels of stress experienced by individuals. In this study, the Cronbach's alpha coefficient of the scale was 0.85. [Study 2 Dataset] 1 participant On the premise of respecting students' wishes, 20 participants were selected from the top 27% of participants in Study 1 regarding their level of mobile phone dependence. Among them, there were 10 participants in the intervention group (3 males and 7 females), with an age distribution of 12-14 years old (12.60 ± 0.70); The control group consists of 10 individuals (5 males and 5 females), with an age distribution of 12-13 years old (12.70 ± 0.48). There was no significant difference in pre-test scores between the control group and the intervention group in terms of natural contact, stress perception, and mobile phone dependence. 2 Experimental Design Adopting a two factor mixed design of 2 (intervention group, control group) × 3 (time points: pre-test, post test, and follow-up test), the intra group variable is the group, the inter group variable is the measurement time point, and the dependent variables are natural contact, stress perception, and mobile phone dependence level. 3 Programs The intervention group received natural contact group counseling for 45 minutes once a week for 8 consecutive weeks. The control group did not intervene in any way. Both groups of students underwent pre-test, post test, and follow-up tests using the Natural Exposure Scale, Chinese version of the Stress Perception Scale, and Mobile Phone Dependence Scale (same study one) before, after, and one month after the intervention. The design of the natural contact group assistance program refers to horticultural therapy and fully utilizes the natural stimulation on campus. The content of horticultural therapy includes five categories: indoor planting, outdoor planting, hiking, group activities, and handicrafts (Guo Yuren, 2005). Under the premise of school safety management regulations, the plan (see dataset) should include the above content as much as possible.
