Aims:To examine the effectiveness of a self-management intervention compared with usual care in adults with chronic kidney disease (CKD) on self-management, knowledge, self-efficacy, health-related quality of life, and blood pressure. Design:A parallel group randomized controlled trial. Methods:Patients aged ≥ 18 years with CKD stages 3-5 were recruited between November 2015 and June 2016. Participants were randomly allocated into either the intervention (N = 68) or control group (N = 67). The control group received usual care, while the intervention group received usual care plus a self-management programme from a nurse. The intervention was guided by social cognitive theory (SCT) and included a face-to-face educational session followed by telephone support. Both groups were followed for 16 weeks.Results: There were no significant differences in self-management, knowledge, selfefficacy, health-related quality of life, and blood pressure between the two groups at baseline. At week 16, compared with the control group, large effect sizes for improved self-management, knowledge, and self-efficacy were detected. For healthrelated quality of life, the physical and mental health components significantly improved. However, no significant differences in either systolic or diastolic blood pressures were found. Conclusion:In earlier stages of CKD, a simple self-management education benefits patients.Impact: Effective self-management in the earlier stages of CKD contributes to slowing its progression, improving health outcomes and lowering the burden on healthcare systems. This study demonstrated that SCT increases CKD self-management by strengthening knowledge and self-efficacy. Nurses can give this education.Trial registration: Australian New Zealand Clinical Trials Registry ACTRN12616000 038493.

This work studied self-reports from adolescents on how the COVID-19 pandemic has changed their behaviors, relationships, mood, and victimization. Data collection was conducted between September 2020 and February 2021 in five countries (Sweden, the USA, Serbia, Morocco, and Vietnam). In total, 5114 high school students (aged 15 to 19 years, 61.8% females) responded to our electronic survey. A substantial proportion of students reported decreased time being outside (41.7%), meeting friends in real life (59.4%), and school performance (30.7%), while reporting increased time to do things they did not have time for before (49.3%) and using social media to stay connected (44.9%). One third of the adolescents increased exercise and felt that they have more control over their life. Only a small proportion of adolescents reported substance use, norm-breaking behaviors, or victimization. The overall COVID-19 impact on adolescent life was gender-specific: we found a stronger negative impact on female students. The results indicated that the majority of adolescents could adapt to the dramatic changes in their environment. However, healthcare institutions, municipalities, schools, and social services could benefit from the findings of this study in their work to meet the needs of those young people who signaled worsened psychosocial functioning, increased stress, and victimization.
