To explore the mediation role of smartphone addiction on the relationship between parent-child relationships and the intensity of use of social network sites (SNSs), as well as the moderation effect of anxiety, this research conducted self-report questionnaires of the Social networking site (SNS) Usage Questionnaire, Self-Rating Anxiety Scale, Smartphone Addiction Scale and Inventory of Parent and Peer Attachment with 719 adolescents. The results showed that (1) the parent-child relationship negatively predicts SNS usage and (2) smartphone addiction plays a mediating role in the link between the parent-child relationship and SNS usage. (3) The relationship between the parent-child relationship and SNS usage is moderated by anxiety (on the first mediation path), and low levels of anxiety can mitigate the negative impact of the parent-child relationship on smartphone addiction, thus also mitigating the negative effects of the parent-child relationship on SNS usage. Our conclusion highlighted the vital role of the parent-child relationship and anxiety on the influence of smartphone addiction and the intensity of use of SNSs among adolescents. Our research also provides clinical implications: (1) teachers in high school can adopt family group counseling or emotion regulation workshop to help adolescents to prevent addiction to smartphones and social network sites; (2) we can reduce addictive behaviors by designing a series of intervention sessions to improve parent-child relationships and reduce anxiety for adolescents who have been addicted to smartphone and social network sites.

The smart age has created new goals, and offers novel approaches for teachers’ professional development. The acquisition of technological pedagogical content knowledge (TPACK) has become essential for novice university teachers’ professional development. With the aim of developing teachers’ TPACK, this study constructed a BOPPPS–TPACK training model by following four key design principles: smart-tool-based, pedagogy-driven, microteaching-integrated, and creatively enhanced. This paper describes a practical study involving 145 teachers that was carried out using questionnaire surveys, interviews, and electronic record analyses. The results showed that the BOPPPS–TPACK training process could achieve the effective coupling of BOPPPS and TPACK and enhance novice university teachers’ ability to engage in in-depth learning and TPACK transfer, creating a method and system to guide teachers’ professional development. Measures such as optimizing the construction of smart environments for teachers’ professional development, enriching pedagogical content of knowledge-based representations, and extending feedback collection to practical settings can help to enhance TPACK development.

Background: Comorbidity between non-suicidal self-injury (NSSI) and depression and anxiety was common. In the framework of network theory, the examination of directionality and gender differences in longitudinal relationships at the symptom level made a significant contribution to the understanding of comorbidity. Therefore, this study employed cross-lagged panel network analysis to investigate the longitudinal interrelations between NSSI and depression and anxiety in Chinese adolescents, with a focus on gender differences. Method: The study was conducted with a sample of 884 senior high school students (F/M: 481/403; mean age: 15.19 ± 0.48 years) from Jinchang City, Gansu Province, China. All respondents completed the Adolescent Non-Suicidal Self-Injury Assessment Questionnaire and the two subscales (depression and anxiety) of the Brief Symptom Inventory at two intervals. The data were estimated in R 4.2.0 to construct the cross-lagged panel network (CLPN). Results: The CLPN results uncovered the gender differences. For boys, self-hitting and feeling scared emerged as central symptoms. Cutting predicted subsequent feelings of sadness (β = − 0.57), tension (β = − 0.52) and indifference (β = − 0.49), potentially serving as a bridge connecting NSSI to depression and anxiety. For girls, biting themselves and feeling scared were central symptoms. Carving and skin rubbing predicted subsequent feelings of indifference (β = − 0.31, −0.21), bridging NSSI to depression and anxiety. In addition, feeling scared emerged as the key bridge symptom connecting depression and anxiety. Conclusion: The findings showed the gender-specific developmental characteristics of the directional relations between NSSI and depression and anxiety at the symptom level. They provided new insights into the comorbidity of NSSI and depression and anxiety, carrying important implications for the screening and intervention of adolescent NSSI.

The aging population represents a formidable global challenge, with China experiencing an accelerated demographic shift. While previous research has established a directional link between mental health literacy, social participation, and active aging, the moderating effect of socioeconomic status (SES) on these associations remains underexplored. This study sought to address this gap by employing moderated network analysis, in contrast to the total score approaches commonly used in prior literature. A cross-sectional design was implemented, involving 1,032 Chinese individuals aged 60 and above, who completed the Mental Health Literacy Questionnaire, Active Aging Scale, Social Participation Questionnaire, and Socioeconomic Status Index Scale. The moderated network method was applied to explore the bidirectional relationships between mental health literacy, social participation, and active aging, while examining the moderating role of SES. The analysis identified the strongest bidirectional relationships between attitudes toward mental illness and the development of spiritual wisdom. Seven interaction terms emerged involving mental health literacy, social participation, and active aging, moderated by SES. Notably, the most significant interaction terms were found between attitudes toward mental illness and engagement in active learning. These results contribute novel insights into the bidirectional relationships among mental health literacy, social participation, and active aging, as well as the role of SES in moderating these relationships. The findings highlight the need for targeted policy interventions to address socioeconomic inequalities in later life, thereby fostering active aging.

The present study was conducted twice over one year during the COVID-19 pandemic with Chinese adolescents (n = 1582) to investigate the relationships among family socioeconomic status (SES), adolescent mental health problems, trait mindfulness, and perceived stress using self-reported measures. We administered the Mindful Attention Awareness Scale (MAAS), the Perceived Stress Scale (PPS), the Self-rating Anxiety Scale (SAS), the Epidemiologic Studies Depression Scale (CES-D), and Conduct Problem Tendency Inventory (CPTDI) to a sample of Chinese adolescents. The results prove that (1) there were significant correlations among socioeconomic status, trait mindfulness, perceived stress, and adolescent mental health problems, and the (2) serial mediation analysis indicated that trait mindfulness and perceived stress performed as mediators on the path from SES to anxiety, depression, and externalizing problems. Our findings provide a contribution by showing the connection between socioeconomic position and adolescent mental health problems and by offering a reference for the treatment of psychological issues affecting adolescents.

We explored differences in performance on the Synthetic House–Tree–Person Test between people with mainly positive symptoms and those with mainly negative symptoms of schizophrenia and, further, aimed to provide a basis for the diagnosis of schizophrenia symptom type. Participants were 58 people receiving treatment for schizophrenia, and we asked them to complete the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms, and the Synthetic House–Tree–Person Test. There were significant differences in results on the Synthetic House–Tree–Person Test between the group with positive symptoms, the group with a mix of positive and negative symptoms, and the group with negative symptoms. There were 12 features of participants' drawings, such as big hands, which were correlated with hallucinations and delusions in positive symptoms, and 9 features, such as trees in a landscape, which were correlated with avolition and anhedonia in negative symptoms. Our study results suggest differences in performance on the Synthetic House–Tree–Person Test between these different symptom subtypes of schizophrenia; hence, the features that appear in drawings made during the test may contribute to the diagnosis of symptoms of people with schizophrenia.
