Migrant Elderly's Social Network Use Intervention: An Activity Theory-Based Study

This study employed a randomized controlled trial (RCT) design, recruiting migrant elderly from a community in Huzhou City as participants. They were randomly assigned to an intervention group and a control group. The control group (n=30) received routine social activities, with compensatory intervention provided after the experiment. The intervention group (n=31) underwent a scientifically valid and operationally feasible practical intervention program, which was developed based on the questionnaire survey method, experimental method, and semi-structured interview method, guided by the Activity Theory, and lasted for 12 weeks. Before the intervention, after 12 weeks of intervention, and one month after the intervention concluded, standardized scales were used to assess the levels of proactive social network use, basic psychological needs, social isolation, and e-health literacy, respectively. For data analysis, independent-samples t-tests and Spearman correlation analysis were performed based on data distribution patterns and homogeneity of variance, while multiple linear regression was applied for multivariate analysis. Inter-group comparisons post-intervention utilized two independent-samples t-tests and Mann-Whitney U tests, whereas intra-group comparisons employed paired-samples t-tests and Wilcoxon signed-rank tests. The significance level was set at α=0.05.
