Effectiveness of a 4-Day Mindfulness-Based Intervention in a 2-Month Follow-Up for Chinese Incarcerated People.

Mindfulness-based interventions, an evidence-based stress reduction approach, may help incarcerated people cope with stress-related problems in the challenging environment of prison. However, due to their unique living environment, the duration and instructor guidance required by standard mindfulness-based interventions would be infeasible in most prisons. Therefore, the aims of the current study were to test the effects of two different 4-day interventions (i.e., instructor-guided and audio-based) with content similar to Mindfulness-Based Cognitive Therapy for newly incarcerated males, and to compare the effectiveness of the two interventions relative to a no-intervention control group. Using daily assessments, we explored changes in perceived stress, insomnia, and negative affect in the 56 days following the instructor-guided (N = 25), audio-based (N = 21), and control (N = 44) intervention; length of mindfulness practice during the follow-up was also compared between the two intervention groups. Hierarchical linear model results showed significantly greater linear decreases in perceived stress after both mindfulness interventions during the 56-day follow-up (γ11 = -0.011, p < .001, 95% CI [-0.017, -0.004] for instructor-guided intervention; γ12 = -0.013, p < .001, 95% CI [-0.018, -0.006] for audio-based intervention), as compared to the control group. Compared to the control group, the instructor-guided group reported a significantly greater decrease in insomnia (γ11 = -0.007, p < .001, 95% CI [-0.014, -0.002]), but the audio-based group did not (γ12 = -0.002, p = .160, 95% CI [-.007, .004]). Neither mindfulness-based intervention group reported a significantly greater decrease in negative affect compared to the control group (γ11 = -0.002, p = .170, 95% CI [-0.005, 0.001] for instructor-guided intervention; γ12 = -0.002, p = .150, 95% CI [-0.006, 0.002] for audio-based intervention). No significant difference between the two intervention groups was found in the change of outcomes (γ11 = 0.002, -0.005 and 0.000, p = .350, .130 and .390, 95% CI [-0.008, 0.011], 95% CI [-0.014, 0.004] and 95% CI [-0.004, 0.006] subsequently for perceived stress, insomnia and negative affect). Daily mindfulness practice was significantly longer for the audio-based group on the first day of follow-up (γ02 = -0.758, p < .05, 95% CI [-1.333, -0.129]), but it gradually decreased to the same amount as the instructor-guided group (t (32) = 0.051, p = .959). Short-term mindfulness interventions, either instructor-guided or audio-based, appear to be beneficial for Chinese prisoners in reducing stress. Live instruction may have potential benefit in reducing insomnia and sustaining daily practice.

Effects of Basketball and Baduanjin Exercise Interventions on Problematic Smartphone Use and Mental Health among College Students: A Randomized Controlled Trial.

Problematic smartphone use (PSU) has become a prevalent issue worldwide. Previous studies suggest that physical exercising may effectively reduce smartphone users' addiction levels. Comparisons and further evaluations on the long-term effects of different types of exercise-based interventions on treating PSU remain to be investigated. Objective. We investigated if group-based basketball and Baduanjin exercise (a type of Qigong) would reduce PSU and improve the mental health of college students and whether such effects would be sustained. A twelve-week experiment was conducted, where 96 eligible Chinese college students with PSU were randomly assigned to two intervention arms (i.e., basketball and Baduanjin exercises) and a control arm. Outcome measures, including PSU (measured by the Mobile Phone Addiction Index in Chinese (MPAI)) and mental health indices for anxiety (measured by Self-Rating Anxiety Scale (SRAS)), loneliness (measured by the short-form of the UCLA Loneliness Scale (UCLA-LS)), inadequacy (measured by the revised Janis and Field's Feelings of Inadequacy Scale (FIS)), and stress (measured by the Chinese version of Perceived Stress Scale (CPSS)) were collected at the baseline, the end of week 12, and the two-month follow-up. A Generalized Estimating Equations (GEE) model for longitudinal data was utilized in analyses. Results. Both exercise interventions demonstrated significant effects on decreasing PSU (basketball: p < 0.01; Baduanjin: p < 0.01), feelings of anxiety (basketball: p < 0.01; Baduanjin: p=0.04), loneliness (basketball: p < 0.01; Baduanjin: p < 0.01), inadequacy (basketball: p < 0.01; Baduanjin: p < 0.01), and perceived stress (basketball: p < 0.01; Baduanjin: p=0.04), at the end of interventions. At two months after interventions, both exercise interventions demonstrated significant effects on decreasing PSU (basketball: p < 0.05; Baduanjin: p < 0.05), feelings of anxiety (basketball: p < 0.01; Baduanjin: p=0.03), loneliness (basketball: p < 0.01; Baduanjin: p < 0.01), and inadequacy (basketball: p < 0.01; Baduanjin: p=0.01), but not for feeling of stress. Furthermore, group-based basketball demonstrated larger improvements for all these significant results on reducing PSU and meanwhile improving their related mental health parameters among college students.
