Effectiveness of cognitive behavior therapy for sleep disturbance and glycemic control in persons with type 2 diabetes mellitus:A community-based randomized controlled trial in China

BACKGROUND Poor sleep quality is a common clinical feature in patients with type 2 diabetes mellitus(T2DM),and often negatively related with glycemic control.Cognitive behavioral therapy(CBT)may improve sleep quality and reduce blood sugar levels in patients with T2DM.However,it is not entirely clear whether CBT delivered by general practitioners is effective for poor sleep quality in T2DM patients in community settings.AIM To test the effect of CBT delivered by general practitioners in improving sleep quality and reducing glycemic levels in patients with T2DM in community.METHODS A cluster randomized controlled trial was conducted from September 2018 to October 2019 in communities of China.Overall 1033 persons with T2DM and poor sleep quality received CBT plus usual care or usual care.Glycosylated hemoglobin A1c(HbAlc)and sleep quality[Pittsburgh Sleep Quality Index(PSQI)]were assessed.Repeated measures analysis of variance and generalized linear mixed effects models were used to estimate the intervention effects on hemoglobin A1c and sleep quality.RESULTS The CBT group had 0.64,0.50,and 0.9 lower PSQI scores than the control group at 2 mo,6 mo,and 12 mo,respectively.The CBT group showed 0.17 and 0.43 lower HbAlc values than the control group at 6 mo and 12 mo.The intervention on meanΔHbAlc values was significant at 12 mo(t=3.68,P<0.01)and that meanΔPSQI scores were closely related toΔHbAlc values(t=7.02,P<0.01).Intentionto-treat analysis for primary and secondary outcomes showed identical results with completed samples.No adverse events were reported.CONCLUSION CBT delivered by general practitioners,as an effective and practical method,could reduce glycemic levels and improve sleep quality for patients with T2DM in community.

Components of complex interventions for healthcare: A narrative synthesis of qualitative studies

Objective:Qualitative research on therapeutic components is necessary to evaluate the efficacy of complex interventions in healthcare.As few qualitative syntheses have been conducted,this study aimed to derive a new conceptual framework for understanding the components of complex interventions and provide evidence for the implementation and evaluation of complex healthcare interventions.Methods:A systematic search of seven databases was conducted to identify qualitative studies that explored components of complex healthcare interventions.Meta-ethnography was used to analyze the data and thematic analysis was used to build the conceptual framework.Results:Of the 35 included studies,most complex interventions were non-pharmacological,with cancer accounting for 22%,mental health for 14%,and stroke for 8%.Half of the studies were conducted in the United Kingdom.Three main categories emerged:what should healthcare workers do?what qualifications should they have?and what should patients do?Five main themes were identified:psychological,biological,cognitive and behavioral,environmental,and social support.Conclusion:This analysis provides a reference for designing components of complex interventions in further studies.

Effect of distinct psychological interventions on changes in selfreported distress,depression and loneliness among older adults during COVID-19

BACKGROUND Older adults have been considered a primary at-risk population during the coronavirus disease 2019(COVID-19)pandemic,and many efforts have been and still are directed toward supporting them and enhancing their capacity to cope with the pandemic.Evidence shows that by enhancing proactive coping abilities through psychological interventions,in which cognitive-behavioral and mindfulness techniques are taught and practiced effectively,these interventions have supported older adults throughout the pandemic.However,the underlying mechanisms by which specific intervention components affect various mental states such as distress,depression and loneliness among older adults remain unclear and warrant investigation.AIM To determine the effect of an intervention using cognitive-behavioral and mindfulness techniques on changes in distress,depression and loneliness.METHODS We performed a secondary analysis on data from a previous study in which community-dwelling older adults attended a short-term,internet-based intervention during the first COVID-19 wave in Israel.The intervention included seven sessions during which various cognitive-behavioral and mindfulness techniques were learned and practiced.In-session changes in psychological distress were measured using the Subjective Units of Distress Scale(SUDS),which participants rated at the beginning and end of each session.Participants also filled out questionnaires that evaluated levels of depression[Patient Health Questionnaire(PHQ-9)]and loneliness(UCLA loneliness Scale)prior to and after the entire intervention process.The effect of in-session changes in the SUDS on changes in post-intervention depression and loneliness levels were assessed,as a proxy for distinct technique effectiveness.RESULTS The findings indicated in-session differences in terms of a decrease in psychological distress(SUDS).Sessions that included relaxation exercises and guided imagery,as well as sessions that included cognitive restructuring and mindfulness meditation,demonstrated the largest decreases in in-session psychological distress(≥35%).Two multivariate regression models,one for levels of post-intervention depression(PHQ-9 score)and the other for levels of post-intervention loneliness(UCLA loneliness score),were fitted.The results revealed two statistically significant explanatory variables for depression:The SUDS difference for sessions in which cognitive restructuring and mindfulness meditation were practiced,beta=-0.25,95%CI:-1.23 to-0.1,and the pre-intervention level of depression,beta=0.62,95%CI:0.37-0.75.The second model for loneliness revealed only one significant explanatory variable:The SUDS difference for sessions in which relaxation and guided imagery were practiced,beta=0.41,95%CI:0.14-0.65.CONCLUSION Different psychological techniques seem to have different effects on distress,loneliness and depression.Understanding the pathways by which distinct techniques affect negative mental symptoms has implications for future intervention design.

在线协作会话中教师干预对学习者认知加工过程的影响研究

在线协作会话是一种广泛应用于在线学习和混合式学习的协作学习活动,教师干预则被认为是提升在线协作会话效果的重要手段之一。然而,教师干预到底如何影响学习者的认知加工过程尚不明确。文章以某大学31名教育技术学专业学生为研究对象,通过准实验研究探索在线协作会话活动中教师干预对学习者认知加工过程的影响。研究结果显示:教师干预对学习者的行为参与没有显著影响;对学习者观点的认知复杂性有抑制作用,而对观点的认知科学性有促进作用;能够促使学习者拥有更丰富的认知模式,使其观点从“前科学”更多地向“具体的事实和解释”转换。基于上述结论,文章进一步得出如下启示:在线协作会话中,教师可以通过设置最低参与标准来促进学习者的行为参与;学习者可以从在线协作会话的教师干预中获益,形成更丰富的认知模式;教师的干预应更加注重对学习者观点的认知复杂性的引导。
