January 2025
Background: Women and sexual minority individuals have been found to be at higher risk for experiencing poor sleep health compared to their counterparts. However, research on the sleep health of sexual minority women (SMW) is lacking in China.
Objective: This study aimed to examine sleep quality and social support for Chinese women with varied sexual identities, and then investigate the in-depth relationships between sexual identity and sleep.
Purpose: To conduct a formative evaluation of ChatEx to increase and maintain exercise among older cancer survivors.
Methods: ChatEx is a blended intervention involving 12 weeks of theory-based instant messages and two in-person training sessions. This pilot study comprises three phases: (1)intervention development: developing a message library reviewed by experts; (2)message library pretesting: exploring the views of older cancer survivors toward the message library and making modifications (n = 20); and (3)intervention pilot testing: piloting the ChatEx using a non-randomized quasi-experimental design using quantitative and qualitative methods among cancer survivors aged 65+ who do not meet current exercise guidelines and have completed treatment (n = 40).
Introduction: Technology-facilitated sexual violence and abuse (TFSVA) refers to a range of behaviours in which digital technologies are used to facilitate both virtual and face-to-face sexual harm. The proliferation of smartphone usage and increasing internet penetration rates across the world have made it easier for individuals to become perpetrators and victims of TFSVA. Since empirical studies of TFSVA remain limited in the academic arena, and there is an absence of evidence to support the development of a standardised TFSVA measurement, this review aims to explore what TFSVA measurements are currently available and their potential use in measuring TFSVA.

Objective: This systematic review aimed to identify and evaluate the effectiveness of interventions developed to mitigate RCs among individuals with cancer.
Article Synopsis
- Early identification of high-risk children and adolescents for weight issues is essential for preventive strategies, and this study focuses on using machine learning techniques to pinpoint key predictors.
- The research analyzed various demographic, physical, and psychological factors to model weight status over one, three, and five-year periods, employing four feature selection methods to determine the most impactful predictors.
- With a large dataset of over 3.8 million student visits, the study successfully identified a minimal set of influential features, achieving high prediction accuracies (up to 0.82) and demonstrating that factors like weight, height, sex, self-esteem, and age are consistently significant predictors of weight problems.
Article Synopsis
- The study focused on using Internationalization at Home (IaH) strategies, combined with the Community of Inquiry (CoI) framework, to improve cultural awareness among nursing students in an online community nursing course.
- It involved a pre-test/post-test design with 106 nursing undergraduates, utilizing a validated Cultural Awareness Scale to measure the effectiveness of the implemented strategies.
- Results indicated a significant increase in students' cultural awareness after using CoI-guided online IaH strategies, emphasizing the need for alignment with course content and technology to enhance student engagement and learning.
