The Effects of Motivational Interviewing on Promoting Human Papillomavirus Vaccination Initiation and Completion Among South Asian Mother/Daughter Dyads: A Pilot Randomised Controlled Trial

Abstract Background Vaccination against HPV is an effective strategy for the prevention of HPV infection and cervical cancer. Nevertheless, the HPV vaccine uptake rate is low among ethnic minorities in Hong Kong. This study sought to assess the feasibility and acceptability of motivational interviewing among South Asian mother–daughter dyads and to preliminarily examine its effects on knowledge of HPV infection and vaccination, health beliefs, intention to have the daughters vaccinated, and initiation and completion of HPV vaccine series. Methods This was a pilot randomised controlled trial. Forty South Asian mothers with at least one daughter aged 9 to 17 years were recruited. The intervention group received a motivational interviewing intervention whereas the control group received usual care. Structured questionnaires were used to collect data on the participants’ characteristics and selected outcome variables. Bias-corrected Hedges’ g and rate difference together with their 95% confidence intervals were calculated to estimate the effect sizes of the intervention on the outcomes The acceptability was assessed via semi-structured interviews. Results A larger proportion of the daughters of the intervention group participants had received the first dose of HPV vaccine (95% [19 out of 20]) vs 0% [0 out of 20]). The intervention group showed greater improvement in knowledge at 3 months after the intervention (Hedges’ g = 0.77 (95%CI:0.13–1.41)). Most interviewees were satisfied with the intervention. Conclusion The intervention was feasible and acceptable. The intervention can help to increase South Asian mothers’ knowledge and to increase the initiation of HPV vaccine series by their daughters. Trial registration This study was registered at the Chinese Clinical Trial Registry (ChiCTR2100052751) on 5 November 2021.

Effectiveness of motivational interviewing in enhancing cancer screening uptake amongst average-risk individuals: A systematic review

Although cancer is a worldwide public health problem, it can be detected early and prevented through cancer screening. Recommendations for screening methods and screening intervals are currently available for several types of cancer. However, not all average-risk individuals are motivated to undergo cancer screening. To examine the effectiveness of motivational interviewing that targets average-risk individuals regarding their cancer screening intention and uptake and to provide recommendations for the content and format of motivational interviewing based on the existing evidence. A systematic literature search was performed using four databases and a manual search. A combination of keywords including 'motivational interviewing', 'cancer screening', 'screening intention' and 'screening uptake' were used to identify relevant articles. Only randomised controlled trials that examined the effects of motivational interviewing amongst average-risk individuals were included in the review. The Cochrane Risk of Bias Tool was used to appraise the methodological quality of the selected articles. The findings were summarised in narrative and tabular formats. Six randomised controlled trials that used motivational interviewing to enhance cancer screening uptake or intention were included in the review. The findings show that motivational interviewing that used a face-to-face and telephone-based approach or were used together with a tailored or reminder letter enhanced the participants' uptake of breast and cervical cancer screening and their intention to undergo future cervical cancer screening. Mixed results were observed in the effectiveness of single-contact motivational interviewing on colorectal cancer screening. The use of motivational interviewing has demonstrated improvements in the uptake of breast and cervical cancer screening. However, more research is warranted in view of the inconclusive findings noted for colorectal cancer screening. Further studies with more rigorous methods are needed to identify the most effective interventions and to test the feasibility and efficiency of the use of Internet-based information communication technology to deliver motivational interviewing.

Use of a Linguistically Appropriate Decision Aid for Cervical Cancer Screening of South Asian Ethnic Minority Women in Hong Kong: A Pilot Randomised Controlled Trial

Decision aids have been shown to be effective in assisting the decision-making process in healthcare settings. This study aimed to examine the feasibility and acceptability of a linguistically appropriate printed decision aid for cervical cancer screening in South Asian women and to preliminarily estimate its effects on decisional conflicts, clarity of values, risk perception, the screening decision and screening uptake. This was a pilot randomised controlled trial. Forty-eight South Asian women aged 25 to 64 years were recruited and allocated to either the intervention group or control group. The participants in the intervention group read a linguistically appropriate printed decision aid. All of the participants in the intervention group agreed that the decision aid was useful in aiding their decision-making. These participants showed significantly greater improvement in decisional conflicts, clarity of values and risk perceptions than those in the control group (all p < 0.05). The screening uptake rate was significantly higher in the intervention group than in the control group (p < 0.001). The decision aid was feasible and acceptable among South Asian women, and it resulted in reduced decisional conflict and increased screening uptake compared with usual care. To improve the convenience of using decision aids, they could be developed in various forms, such as printed and mobile application forms, to meet individual requirements. The trial was registered at the Chinese Clinical Trial Registry on 23 October 2021 (ChiCTR2100052225).

Educational Interventions to Promote Cervical Cancer Screening among Rural Populations: A Systematic Review

The urban–rural gap in cervical cancer screening uptake is a significant public health consideration. Educational interventions are commonly adopted to promote cervical cancer screening among females in rural areas; however, the characteristics and effectiveness of these educational interventions remain unclear. In this review, we aimed to identify the characteristics of educational interventions used in rural populations and to evaluate the effects of these interventions on cervical cancer screening-related outcomes. Seven English databases were searched in January 2022. Randomized controlled trials (RCTs) and quasi-experimental studies were included. The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Randomized Controlled Trials and the JBI Critical Appraisal Checklist for Quasi-Experimental Studies were used for quality appraisal. RevMan 5.4 software was used for the meta-analysis. A narrative synthesis was conducted in instances where a meta-analysis was inappropriate. Three RCTs and seven quasi-experimental studies conducted in six countries were included. A social cognitive theory-based framework, the community setting, group sessions, healthcare professional-led approaches, and culture-tailored materials were implemented in the educational interventions for cervical cancer screening. The educational content mainly included basic information on cervical cancer screening, psychological issues, barriers and strategies to overcome them, and locally available resources. Educational interventions increased the knowledge and uptake of cervical cancer screening in the rural population. However, the studies only evaluated the short-term effects of these educational interventions, with the cervical screening behavior only being assessed in one instance for each participant. Educational interventions promote cervical cancer screening among females in rural areas. Theory-driven, community-involved, group-based, and healthcare professional-led approaches should be prioritized in the application of educational interventions in rural populations. Both the short- and long-term, influences of educational interventions on the cervical cancer screening behavior of females in rural areas need to be recognized.

Exploring the Barriers and Facilitators Influencing Human Papillomavirus Vaccination Decisions Among South Asian and Chinese Mothers: a Qualitative Study

Human papillomavirus (HPV) vaccines are safe and effective in preventing HPV infection and HPV-related cancers. However, the HPV vaccine uptake rate is lower among the ethnic minority population than in the majority population. This qualitative study explored the barriers and facilitators influencing South Asian minority and Chinese mothers' decisions to vaccinate their daughters against HPV in Hong Kong. South Asian and Chinese mothers with at least one daughter aged 9 to 17 years were recruited to this study. Twenty-two semi-structured focus group interviews were conducted, and the transcripts were analysed via content analysis. Two barriers and three facilitating factors were common among South Asian and Chinese mothers: inadequate knowledge of cervical cancer, HPV or the HPV vaccine and high perceived barriers to HPV vaccination due to vaccine cost, the receipt of reliable information from schools or the government, high perceived benefits of HPV vaccination to health, and the presence of vaccination programme arranged by school or government. Despite these commonalities, South Asian mothers experienced more barriers to making the decision to vaccinate than Chinese mothers. Particularly, obtaining family support was an important factor for South Asian mothers. The vaccination decision was considered a joint decision between the mother and father, and the father's agreement was of particular importance to Pakistani mothers. This study identified the factors that hindered and facilitated South Asian and Chinese mothers' decisions to vaccinate their daughters against HPV. The comparison between groups improves our understanding of the distinct needs of South Asian in Hong Kong.

Randomised controlled trial of music listening combined with progressive muscle relaxation for mood management in women receiving chemotherapy for cancer

Abstract Aims To evaluate the effects of passive music listening combined with progressive muscle relaxation on anxiety, depression, stress, coping, and quality-of-life in women with breast and gynaecological cancers receiving chemotherapy. Methods This was an assessor-blinded, randomised wait-list controlled trial. A total of 120 participants were randomly allocated into an intervention group or a wait-list control group. The intervention group received an intervention comprising training on passive music listening and progressive muscle relaxation, with once-daily self-practice at home for 3 weeks. The wait-list control group received the same intervention after the outcome assessment at week 6. All outcome data were collected before (T0) and 3 weeks (T1), 6 weeks (T2), and 12 months (T3) after randomisation. A generalised estimating equations model was used to compare the changes in each outcome at different time points. Process evaluation was conducted using data from the patient’s self-report forms and interviews. Results The findings indicated that at T1 and T2, the intervention group’s reductions in anxiety were significantly larger than those of the control group. Additionally, the intervention group exhibited significantly better decreases in depression at T2, stress at T1, and dysfunctional coping at T2, and a greater improvement in quality-of-life score at T1 and T2 when compared to the control group. Most of the interviewed participants provided positive feedback on the intervention. Conclusions The intervention was beneficial for lowering anxiety, depression, and stress and increasing the quality-of-life of women receiving chemotherapy for breast and gynaecological cancers. Trial registration. The trial was prospectively registered with ClinicalTrials.gov on 9 February 2022 (registration number: NCT05262621).
