Introduction With mobile technologies becoming more advanced and accessible, mobile health (mHealth) has been incorporated in delivering timely and convenient breastfeeding support. However, its feasibility and potential efficacy remain to be examined. Therefore, the primary objective of this study is to assess the feasibility and acceptability of an online instant messaging peer support group for breastfeeding. The secondary objective is to evaluate the effect of the intervention on breastfeeding outcomes. Methods A pilot randomized controlled trial was conducted. A total of 33 primiparous women were recruited in the antenatal clinic at a public hospital in Hong Kong between March and April 2021. They were randomized to receive either standard care (n = 18) or standard care and receive peer-group support in an online instant messaging app (n = 15). Participants received telephone follow-up for up to six months postpartum or until they stopped breastfeeding. After completing the study, six participants in the intervention group were interviewed to understand their perceptions of the intervention. Results This pilot study shows that online messaging peer support group is feasible and acceptable to women. In total, 54.4% of the eligible women agreed to participate, and 97.0% completed the follow-up. Participants perceived that providing peer support through instant messaging app is appropriate. It serves as a channel for the participants to ask questions and obtain information. Furthermore, meetings of the peer supporters and group members can be held to enhance the effectiveness of the intervention. In addition, no significant differences were found in any and exclusive breastfeeding rates, breastfeeding attitude, and breastfeeding self-efficacy between the two groups. Conclusions This study shows that online messaging peer support group is feasible and acceptable. A full-scale study should be conducted to understand the effect of the online instant messaging peer support group on breastfeeding outcomes. Trial Registration: The study protocol is registered on Clinicaltrial.gov (NCT04826796) on 1 April 2021

Background Mobile health, the use of mobile technology in delivering health care, has been found to be effective in changing health behaviors, including improving breastfeeding practices in postpartum women. With the widespread use of smartphones and instant messaging apps in Hong Kong, instant messaging groups could be a useful channel for delivering breastfeeding peer support. Objective The aim of this paper is to study the feasibility and acceptability of an online instant messaging peer support group by trained peer counselors on improving breastfeeding outcome in primiparous women in Hong Kong. Methods A two-arm, assessor-blind, randomized controlled feasibility study will be conducted on 40 primiparous women with the intention to breastfeed. Participants are recruited from the antenatal obstetrics and gynecology clinic of a public hospital in Hong Kong and randomly assigned at a 1:1 ratio to either intervention or control group. The intervention group receives peer support in an online instant messaging group with trained peer counselors on top of standard care, whereas the control group receives standard care. Breastfeeding outcome will be assessed for 6 months post partum or until weaned. The breastfeeding status, the proportion and duration of exclusive and any breastfeeding in each group, and the self-efficacy and attitude of participants will be assessed. The feasibility and acceptability of the study would also be assessed in preparation for a full randomized controlled trial. Results This study (protocol version 1 dated January 5, 2021) has been reviewed and approved by the institutional review board of the University of Hong Kong, Hospital Authority Hong Kong West Cluster (reference UW 21-039), on January 26, 2021. Data collection is ongoing and expected to be completed in December 2021. The findings will be updated on clinical trial registry and disseminated in peer-reviewed journals. Conclusions This study aims to assess the feasibility and effectiveness of an online instant messaging peer support group in improving the breastfeeding outcome of primiparous women in Hong Kong. Its findings could inform the feasibility of a full-scale trial with this intervention design.

BACKGROUND Stroke brings about abrupt and immense changes to stroke families’ dynamics and responsibilities. Adaptation to new family roles is challenging, as support for caregivers of stoke survivors is minimal, presenting a major obstacle towards restoring family functioning and maximizing care capacity. OBJECTIVE This study aims to implement and examine the effectiveness of a two-tier family- oriented intervention involving care managers and volunteers for enhancing family functioning and care capacity of family caregivers of stroke survivors. METHODS This is a multicenter, two-armed, randomized, controlled study (intervention group, n=150; control group, n=150). Following case referral from hospital, family caregivers of stroke survivors and stroke survivors provide informed consent and undergo initial screening. Caregivers report significant caregiver burden, and/or depressive mood, and/or family dysfunctioning are randomly assigned to undergo two-tier family-oriented intervention (intervention group) or psychoeducation (control group). The primary outcome is the change in i) family role performance, ii) family caregiver conflict, iii) care management strategies, and iv) general family functioning from baseline to 2 weeks and 2 months after completion of intervention. RESULTS This study began in January 2017 and is being conducted at three participating facilities in Hong Kong. CONCLUSIONS This study will examine the effectiveness of a two-tier family- oriented intervention in enhancing family functioning and care capacity of family caregivers of stroke survivors. Through this study, we expect that this intervention can fill the service gap in the current stroke care system and serves as an important basis on which future evidence-based programs supporting family caregivers of stroke survivors could develop.
