To determine the treatment effectiveness associated with mobile health-delivered cognitive behavioural therapy for insomnia (mCBT-I) interventions for adults with insomnia and to identify the potential characteristics associated with better treatment outcomes.
A systematic review and meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines.
Seven English- and two Chinese-language databases were searched, without restrictions on publication dates, up to July 2024. Reference lists of relevant reviews and grey literature were included in the search. Randomised controlled trials evaluating mCBT-I in adults with insomnia and published in either English or Chinese were included in this meta-analysis. A random-effects model was used for data analysis, accompanied by additional subgroup analyses and meta-regression.
Sixteen studies involving 2146 participants were included in this meta-analysis. mCBT-I interventions were associated with significantly reduced insomnia symptoms and improved sleep quality at post intervention, at 1–3-month follow-up, and at 4–6-month follow-up. Interventions that included five components of CBT-I, were delivered for 6 weeks or longer, and were conducted in a group format were linked to better treatment outcomes; the differences in other subgroup categories were not statistically significant. Studies involving participants with comorbid conditions showed a greater effect in reducing insomnia symptoms than those without such participants. In addition, mCBT-I interventions delivered by healthcare professionals resulted in statistically larger effect sizes for improving sleep quality than self-help regimens.
The systematic review and meta-analysis identified the effectiveness of mCBT-I in reducing insomnia symptoms and improving sleep quality and offered practical implications for the development of effective mCBT-I interventions in clinical practice. However, future robust studies are needed to explore the long-term effects of mCBT-I interventions.

To evaluate the effects of exergaming on physical frailty in older adults.
Systematic review with meta-analysis.
Six electronic databases were searched for randomised controlled trials evaluating the effects of exergaming on frailty in older adults. Data were synthesised using narrative synthesis and meta-analysis. The risk of bias and the certainty of the evidence were assessed.
CINAHL, Cochrane Library, Embase, PubMed, Web of Science, and China Academic Journal Network Publishing Database were searched from their inception through February 2024.
Five studies (n = 391) were included. Exergaming, which was delivered in 20–36 sessions over 8–12 weeks, resulted in improvements in frailty scores and indices, frailty status, and frailty phenotypes, including exhaustion, low physical activity levels, gait speed, and muscle weakness over time. There was no effect on unintentional weight loss. Meta-analyses showed that the effects of exergaming were not significantly different from those observed in the control groups. The rate of adherence to the intervention of the exergaming group was slightly higher than that of the comparison group (87.3%–87.7% vs. 81.1%–85.4%). The overall risk of bias was high in all studies. The certainty of the evidence was very low.
Exergaming exerts effects on frailty comparable to those of conventional physical exercises. Participants appeared to have better adherence to exergaming. Future studies with robust designs are warranted.
With effects comparable to those of conventional physical exercises, exergaming could be considered in clinical settings to address frailty.
This review addressed the effects of exergaming on frailty instead of physical outcomes. Exergaming was comparable to conventional physical exercises in improving frailty scores and indices, frailty status, and four frailty phenotypes. The findings provide insights to healthcare providers on the design of exergames.

Depressive symptoms are common among people with dementia (PWD). Exergaming consisting of combined cognitive and physical training in gaming is increasingly used to alleviate their depressive symptoms in research. With its potential synergistic neurobiological and psychosocial effects on reducing depressive symptoms among PWD, this review aimed to understand its effectiveness and contents.
This is a systematic review of the effectiveness of exergames on depressive symptoms among older adults with dementia. A search was conducted on 7 May 2024 of the online databases CINAHL, Embase, PsycINFO, PubMed and the China Academic Journal Network Publishing Database (CNKI). The methodological quality of randomised controlled trials (RCT) and quasi-experimental studies was assessed with RoB2 and ROBINS-I, respectively. A meta-analysis of the included RCTs was conducted.
Six studies consisting of four RCTs and two quasi-experimental studies involving 235 participants with various stages of dementia were included. The meta-analysis showed a significant overall improvement in depression with a large effect size (SMD = 1.46, 95% CI = −2.50, −0.43; p = 0.006). Despite high heterogeneity (I 2 = 91%), all studies demonstrated a trend of improvement in depression after the intervention. The exergames adopted in the included trials had the following elements: simultaneous motor-cognitive training, a scoring mechanism and a social play. The dose of exergames ranged from 15 to 60 min per session for at least 8 weeks, with a minimum of two sessions weekly. However, the included studies had a moderate-to-serious risk of bias. The certainty of the evidence was very low.
Exergames could be effective at improving the depressive symptoms of older adults with dementia. Yet, a moderate-to-severe risk of bias shows a rigorous study should be conducted in the future.
This study provides evidence for healthcare professionals and informal caregivers to use exergames to address depressive symptoms in PWD.
The review was registered on PROSPERO with the reference CRD42022372762.
To develop a Chinese version of a chronic wound health-related quality of life (QoL) instrument and to examine the psychometric properties of this instrument.
Existing QoL instruments are not tailored to the linguistic and cultural characteristics of Chinese-speaking patients; a version addressing this gap will increase clinical understanding of their healthcare experience and may help guide chronic wound care.
A methodological study.
The method advanced by DeVellis (2017) was used to develop the instrument. An initial pool of 38 items was created. To optimize scale length and test reliability and validity, exploratory and confirmatory factor analyses were conducted. A total of 23 items formed the final pool. After two rounds of expert discussions, the average content validity index of the final 23 items was .89.
A total of 226 patients completed the instrument and were divided into two groups for further analysis. Exploratory factor analysis revealed that 15 items remained in four factors (social activity restrictions, physical and psychological disturbance, wound burden and daily life limitation), which accounted for 64.87% of the variance. Confirmatory factor analysis revealed an acceptable fit of the hypothesized factor structure and the convergent and discriminant validities were achieved. Cronbach's α coefficients for each factor were .807, .773, .799 and .713, respectively.
The Chinese version of a chronic wound health-related QoL instrument consists of 15 items in four subscales and demonstrates good reliability and validity.
This instrument can be used intermittently or continuously to evaluate the treatment effect of chronic wounds by assessing health-related QoL. Scholars in Chinese-speaking regions may find this culturally compatible instrument useful when conducting studies related to chronic wounds.
Two hundred twenty-six participants provided their perspectives on health-related QoL.
