Development of a Health Empowerment Programme to improve the health of working poor families: protocol for a prospective cohort study in Hong Kong

The Knowledge, Attitudes, and Practices of Healthy Eating Questionnaire: a pilot validation study in Chinese families

Introduction

Identifying the knowledge, attitudes, and practices (KAP) gaps of healthy eating can inform the design of effective interventions. This study aimed to test the validity and psychometric properties of a KAP of Healthy Eating Questionnaire (KAP-HEQ) tailored to the Chinese culture.

Methods

The dimensions and potential items of each KAP scale were identified from published KAP and health literacy questionnaires, which were supplemented by the findings of a previous qualitative healthy eating study. Content validity of the KAP-HEQ was evaluated by eight experts and eight Chinese parent-adolescent dyads in Hong Kong through content validity ratio (CVR), content validity index (CVI), and qualitative feedback. The feasibility, construct validity, reliability, and sensitivity of the KAP-HEQ were evaluated in this pilot study among 60 adolescent-parent dyads (120 persons) through an online survey. The first 30 dyads who completed the KAP-HEQ were invited to repeat the KAP-HEQ 2 weeks later to assess the test-retest reliability.

Results

The final 44-item KAP-HEQ was completed in 10-15 min by both adolescents and their adult parents. The CVR ranged from -0.38 to 1, and the CVI ranged from 0.56 to 1. Over 80% of the items achieved convergent validity (a significantly positive correlation with its hypothesized scale) and discriminant validity (a higher correlation with its hypothesized scale than with the other two scales). Cronbach's alpha for the internal consistency of the Overall, Attitude, and Practice scales was >0.7, while that of the Knowledge scale was 0.54. The intraclass correlation coefficient (ICC) on test-retest reliability of the Overall and individual scales were all >0.75 except that of the Knowledge scale (ICC = 0.58). The significant differences in KAP scale scores with small to large effect sizes were found between known groups as hypothesized, except the Attitude score between groups by household income, which supported the sensitivity of the KAP-HEQ.

Conclusion

The KAP-HEQ has shown good validity, reliability, and sensitivity among Chinese adolescents and adults, which can be applied to evaluate KAP status and gaps to inform the design and assess the effectiveness of healthy eating interventions.

Effectiveness of a 5-year health empowerment programme on promoting cardiovascular health for adults from low-income families in Hong Kong

OBJECTIVE

This study aimed to evaluate the effectiveness of a health empowerment programme (HEP) to enhance cardiovascular health for adults from low-income families.

METHODS

A prospective cohort study (N = 219, Intervention group: n = 103, comparison group: n = 116) was conducted with participants recruited from January 2013 to November 2015 and followed up until January 2022. Throughout the study duration, intervention group were invited to participate in the HEP. The cardiovascular health status of both groups at baseline and follow-up were assessed using the adapted Ideal Cardiovascular Health Index (ICHI) defined by the American Heart Association. After inverse propensity score weighting, multiple linear regression and Poisson regression were employed to examine the effects of the HEP.

RESULTS

The HEP was associated with a greater increase in ICHI total score (B = 0.33, p < 0.001), and the increase of proportion of people achieving a normal blood pressure (Incidence rate ratio: 3.39, p < 0.05).

CONCLUSION

HEP can be an effective and sustainable strategy to reduce social disparities in cardiovascular health of adults from low-income families, as indicated by improvement in the ICHI total score and blood pressure status.

PRACTICAL IMPLICATIONS

The sustainable HEP in the community setting has potential for generalizability and scalability to other financially challenged families.

Association between health-related empowerment and health-protective behaviors among community-dwelling older adults

BACKGROUND

Empowerment is a broad concept seen as a critical approach for helping older adults who lack power to gain control over various aspects of their lives, including their health-protective behaviors.

AIM

The study investigated the association between health-related empowerment and health-protective behaviors in older adults.

DESIGN

A cross-sectional correlational research design was used by recruiting a convenient sample of 200 older adults.

TOOLS

The Elder Health Empowerment Scale and Health Protective Behavior Scale were used to collect the participant data.

RESULTS

It showed a significant positive correlation between health-related empowerment and health-protective behaviors in older adults (r = 0.891, p = 0.001), indicating that as health-related empowerment increases, engagement in health-protective behaviors also increases. Furthermore, health-related empowerment accounted for a large proportion of the variation in health-protective behaviors (85.7 %).

CONCLUSION

Overall, these findings suggest that there is a need for interventions to improve the health-related empowerment of older adults, particularly in terms of their ability to turn their health goals into actionable plans, overcome barriers to health, and make informed healthcare choices. However, the studied older adults generally engage in health protective behaviors; there is variability in the extent to which they engage in specific behaviors, which may provide valuable insights for developing targeted health promotion programs and interventions.

Unpacking the Public Health Triad of Social Inequality in Health, Health Literacy, and Quality of Life-A Scoping Review of Research Characteristics

Social inequalities in health, health literacy, and quality of life serve as distinct public health indicators, but it remains unclear how and to what extent they are applied and combined in the literature. Thus, the characteristics of the research have yet to be established, and we aim to identify and describe the characteristics of research that intersects social inequality in health, health literacy, and quality of life. We conducted a scoping review with systematic searches in ten databases. Studies applying any design in any population were eligible if social inequality in health, health literacy, and quality of life were combined. Citations were independently screened using Covidence. The search yielded 4111 citations, with 73 eligible reports. The reviewed research was mostly quantitative and aimed at patient populations in a community setting, with a scarcity of reports specifically defining and assessing social inequality in health, health literacy, and quality of life, and with only 2/73 citations providing a definition for all three. The published research combining social inequality in health, health literacy, and quality of life is heterogeneous regarding research designs, populations, contexts, and geography, where social inequality appears as a contextualizing variable.

Family Facilitators of, Barriers to and Strategies for Healthy Eating among Chinese Adolescents: Qualitative Interviews with Parent-Adolescent Dyads

Healthy eating is vital in preventing obesity and long-term non-communicable diseases. This study explores potential family facilitators of, barriers to and strategies for healthy eating among adolescents in Chinese families to guide the development of effective interventions in the future. Parent-adolescent dyads were purposively sampled by age, gender, fruit and vegetable intake and household income. Key family factors were identified by thematic analysis. Fourteen themes under five domains were identified: family health with (1) illness experienced in the family; parental knowledge of (2) dietary recommendations, (3) the preparation of healthy food and (4) healthy food choice; parental attitudes towards (5) the importance of healthy eating and (6) the priority of family health; socioeconomic factors of (7) time concerns and (8) cost concerns; and food parenting practices in (9) nutritional education, (10) role modeling, (11) food provision, (12) child involvement, (13) parental supervision and (14) the cultivation of food preference. Useful strategies included incorporating healthy ingredients in adolescents' favorite recipes and providing a variety of fruit and vegetables at home. There is a need to empower parents with practical nutrition knowledge, to be more authoritative in food parenting practices, to discuss healthy eating with children and to acquire practical skills related to time- and cost-saving healthy cooking.

Adolescent Knowledge, Attitudes and Practices of Healthy Eating: Findings of Qualitative Interviews among Hong Kong Families

To tackle unhealthy eating among adolescents, it is crucial to understand the dietary knowledge, attitudes, and practices (KAP) on which adolescent eating habits are based. This qualitative study identifies the gaps in KAP by exploring what Chinese adolescents know, perceive, and practice regarding healthy eating to better inform targeted interventions for this important health problem. Parent–adolescent dyads were purposively sampled based on, for example, the dietary intake, age, and gender of the adolescent and household income, and each completed a 30 to 60 min interview. Twelve themes were synthesized: knowledge: (1) dietary recommendations, (2) health outcomes of healthy eating, (3) nutrition content in food, and (4) access to healthy meals; attitudes: (5) outcome expectation for healthy eating, (6) food preferences, and (7) self-efficacy regarding adopting healthy eating; and practices: (8) going grocery shopping for healthy food, (9) eating home-prepared meals. (10) eating out in restaurants or consuming takeaway food, (11) fruit and vegetable consumption, and (12) snacking, perceived unhealthy eating to be low risk, made unhealthy choices regarding snacking and eating out, and had insufficient fruit and vegetable intake. Programs should emphasize the positive short-term health outcomes of healthy eating and empower adolescents to acquire food preparation skills to sustain healthy eating habits.

Self-Criticism in In-Work Poverty: The Mediating Role of Social Support in the Era of Flexibility

In-work poverty reflects situations of income below the poverty threshold among employed people, involving a deterioration of wellbeing. The International Labour Organization prioritises this situation, which in countries such as Spain, Germany or Italy reaches rates of 11.8%, 10.6% and 11.8%, respectively. Within a context of flexibility, the occupational situation tends to be understood as an individual responsibility, which is why this study analyses the increase in self-criticism in these situations, and the role of social support in this relationship. The mediation of social support in the manifestation of self-criticism among people experiencing in-work poverty is analysed. The participants were 1430 employed people, grouped into those in a situation of poverty and those who are not. The results show that people in a situation of in-work poverty present a higher score in self-criticism and lower in social support. Social support is a mediating variable that prevents the manifestation of self-criticism. Lastly, a gender analysis shows that women experience this relationship more intensely. These findings enable a critical assessment of the activation policies that only take an individual approach. As an alternative, we propose strengthening interventions that foster social support, particularly among women.

Promoting Mental Health During the COVID-19 Pandemic: A Hybrid, Innovative Approach in Malaysia

Background: The COVID-19 pandemic has had monumental effects on the mental health of populations worldwide. Previous research indicated that programs and interventions using social networks can play a positive role in promoting mental health. Nevertheless, current evidence is largely derived from high-income regions, reflecting an urgent need for more studies in low- and middle-income settings.

Objectives: This paper aims to (a) describe the potential value of a hybrid health carnival in promoting mental health and increasing access to screening services; (b) assess the level of community engagement with the digital platform.

Methods: A mental health carnival was conducted with the theme of “Mind Your Mental Health” (Cakna Kesihatan Mental) in conjunction with the World Mental Health Day in Malaysia. This was a hybrid carnival that combined elements of face-to-face interactions and virtual learning. Free online therapy sessions were offered to high-risk groups identified during the screening process. Social media metrics were utilized to report the levels of community engagement and participants completed pre-and post-assessments to measure the program's impact on their knowledge.

Results: The carnival was attended by 515 participants (78.8% virtual participants). Social media metrics reported more than 5,585 reaches on Facebook for all the activities held throughout the event. Results from pre-and post-assessments showed significant improvement in the mean knowledge scores (p < 0.05).

Conclusion: This digital approach will continue to evolve by releasing new features and tools as a new frontier for high-risk populations and all individuals seeking mental health support and treatment.

The validity, reliability, sensitivity and responsiveness of a modified Patient Enablement Instrument (PEI-2) as a tool for serial measurements of health enablement

BACKGROUND

Patient enablement is a core tenet of patient-centred and holistic primary care. The Patient Enablement Instrument (PEI) is a transitional measure limited in its ability to measure changes over time. A modified version, PEI-2, has been developed to measure enablement at a given time-point without comparison to a recalled baseline.

OBJECTIVE

To assess the validity, reliability, sensitivity and responsiveness of PEI-2.

METHODS

PEI-2 was modified from the Chinese PEI to assess enablement over 4 weeks in a prospective cohort study nested within a community support programme [Trekkers Family Enhancement Scheme (TFES)] in Hong Kong. Construct validity was assessed by factor analysis and convergent validity by Spearman's correlations with health-related quality of life and depressive symptoms. Internal reliability was assessed using Cronbach's alpha. Test-retest reliability was assessed by intraclass correlation (ICC), responsiveness by 12-24-month change in PEI-2 score and sensitivity by differences in change of PEI-2 score between TFES participants and a control group.

RESULTS

PEI-2 demonstrated construct validity with all items loading on one factor (factor loadings >0.7). Convergent validity was confirmed by significant correlations with 12-item Short Form Questionnaire, version 2 (r = 0.1089-0.1919) and Patient Health Questionnaire-9 (r = -0.2030). Internal reliability was high (Cronbach's alpha = 0.9095) and test-retest reliability moderate (ICC = 0.520, P = 0.506). Significant improvements in PEI-2 scores among the TFES group suggested good responsiveness (P < 0.001). The difference in change of PEI-2 scores between TFES and control was significant (P = 0.008), indicating good sensitivity.

CONCLUSIONS

This study supports the validity, reliability, sensitivity and responsiveness of PEI-2 in measuring changes in enablement, making it a promising tool for evaluating enablement in cohort and intervention studies.

Psychometric Properties of the Health Empowerment Scale Arabic Version for Working Women in Saudi Arabia

In a country such as Saudi Arabia where gender equality-related challenges continue to be social issues, measuring the health empowerment of Saudi working women is critical in understanding the real picture of women empowerment in the country during this era of great transformation. Therefore, we conducted this research to evaluate psychometric properties of the Health Empowerment Scale Arabic version (HES-A) in measuring the health empowerment of Saudi working women. We surveyed a sample of 322 Saudi working women from June to August 2020 using an online survey constituting questions on demographic and work-related information and the HES-A. The computed values for the item-level content validity index of the 8 scale items were from .80 and 1.00, whereas the computed value of the scale-level content validity index by average method was .91. The principal component and confirmatory factor analyses revealed a unidimentional scale. The computation revealed an alpha of .92. Education, type of employment, years of working experience, and salary were identified as significant factors influencing the health empowerment. The HES-A exhibited adequate validity and internal consistency for use in measuring the health empowerment of Saudi women. The HES-A can expand the research agenda on health empowerment Arab women. Researchers and policymakers could use the HES-A in assessing the status of health empowerment of Arabic-speaking women, which could inform policies and interventions aimed at ensuring health empowered women in this part of the globe.

Development and pilot evaluation of a mobile app on parent-child exercises to improve physical activity and psychosocial outcomes of Hong Kong Chinese children

BACKGROUND

Parent-child exercises involve children and parents to do workout together and have positive effects on physical and mental health. We developed a mobile app on parent-child exercises called Family Move, which combines coaching videos with game features such as points and level system to enhance the health and wellbeing of both children and parents through parent-child exercises. This pilot pre-post study investigated whether the Family Move app-based intervention had a positive effect on children's health-related quality of life (HRQOL), psychosocial wellbeing, and physical activity (PA) level.

METHODS

We recruited 67 parent-child pairs. During the 8-week intervention, these pairs were invited to perform parent-child exercises using the Family Move app. Points were automatically added to the user account after viewing a coaching video. In-game ranking was available to enhance user engagement. Parent proxy-report questionnaires on children's HRQOL, psychosocial wellbeing, and PA were administered at baseline and 1- and 6-month follow-up. Paired samples t-tests were conducted to evaluate post-intervention changes in child outcomes (HRQOL, psychosocial wellbeing, and PA). Multiple linear regressions were used to examine these changes as a function of in-game ranking.

RESULTS

52 (78%) viewed at least one coaching video in the Family Move app. Children's PA level significantly increased at 1-month (d = 0.32, p = 0.030) and 6-month (d = 0.30, p = 0.042) follow-up, whereas their psychosocial problems declined at 6-month follow-up (d = 0.35, p = 0.005). Higher in-game ranking was significantly associated with fewer psychosocial problems at 1-month follow-up (β = - 0.15, p = 0.030).

CONCLUSIONS

Our findings suggest that the Family Move app could be a possible intervention to increase children's PA level and psychosocial wellbeing through parent-child exercise.

Reexamining dental outreach programs: A model for local empowerment and sustainable development

BACKGROUND

To address the inadequacy of oral health care in developing nations, outreach programs have facilitated the provision of dental services by foreign volunteers to areas of need. However, the effectiveness of the current aid model on the long-term well-being of the recipient population and sustainability of efforts remains uncertain. The authors examine the strengths and areas of improvement of outreach initiatives to inform a reorientation of the aid model.

METHODS

The authors conducted a PubMed search and reviewed included articles to assess the current limitations and recommended strategies for outreach programs. The identified limitations and strategies were sorted into 4 key areas of change and organized using the Theory of Change framework to inform an improved aid model.

RESULTS

The current aid models were found to have limitations in scope and coverage, interventions that were not applicable or integrated into local systems, and an inadequate evidence base. To address these limitations, efforts should be directed at the capacity building of local workers through individual training and evidence-based interventions, improved understanding of local contexts, and integration and alignment with local systems.

CONCLUSIONS

The empowerment of local communities is critical in ensuring an effective and sustainable aid model in developing nations.

PRACTICAL IMPLICATIONS

By adopting an improved aid model, outreach programs can enhance the long-term access and availability of quality oral health care that is delivered by local providers and communities.

Do Negative Emotional States Play a Role in the Association Between Intimate Partner Violence and Poor Health-Related Quality of Life in Chinese Women From Low-Income Families?

A cross-sectional analysis of a dataset of 156 participants in a health assessment program explored whether negative emotional states mediated the association between intimate partner violence (IPV) and health-related quality of life (HRQoL). Compared with IPV screen-negative participants, those who screened positive had significantly lower HRQoL and significantly higher levels of depression, anxiety, and stress. The inverse associations between the presence of IPV and HRQoL were found to be mediated by depression, anxiety, and stress. Therefore, interventions to alleviate negative emotions in women suffering from IPV have the potential to be useful in improving their HRQoL.

Balanced nutrition and hand hygiene for children in South Africa

Globally, ∼5.9 million children under the age of 5 years died in 2015, with the challenges of child mortality and morbidity being common in developing countries. Many of these deaths are preventable and poor nutritional and hygienic practices contribute greatly to these rates. The spread of infectious disease through unhygienic practices, such as inadequate hand hygiene, remains high due to lack of education regarding hygienic infection control practices at home and in the workplace. The aim of this research was to design and implement a participatory health promotion intervention for caregivers at the Rhodes Day Care Centre (RDCC) that highlighted these important public health issues. We conducted a pre-intervention group feedback discussion with caregivers at the RDCC to identify current practices and to establish the current baseline knowledge of the caregivers. Health workshops with caregivers was facilitated by the researcher, and health information leaflets (HILs) were designed for and used during these workshops. Caregivers at RDCC exhibited fair baseline knowledge on the importance of providing nourishing meals to the infants, including the need for exclusive breastfeeding, and the importance of hand hygiene in preventing the spread of disease. This basic knowledge was positively built upon in the two health promotion intervention workshops. This initiative, held at RDCC, was able to catalyse the development of health knowledge that could have a substantial impact on the understanding of health literacy of the caregivers and on the promotion of adequate child health in the community.

Objetivos: Estimar a prevalência de pessoas com estomia de eliminação e caracterizá-las quanto aos aspectos sociodemográficos e clínicos. Método: Estudo transversal descritivo com amostra de 27 pacientes com estomias de eliminação, residentes em uma microrregião do norte de Minas Gerais, que atenderam aos critérios de inclusão. Os dados coletados foram registrados em instrumento utilizado em estudos anteriores e analisados por meio de estatística descritiva. Estudo aprovado pelo Comitê de Ética. Resultados: A prevalência de pessoas com estomia foi de 2,16/10.000, a amostra continha 55,6% de homens, 40,7% eram casados, com média de idade de 59,1 anos, 59,2,% eram alfabetizados e 74,0% tinham baixa renda; 59,3% das estomias decorreram de câncer, sendo mais frequentes os de cólon e reto, 70,4% das estomias eram definitivas e 74,0% eram colostomias. Dermatite foi a principal complicação e 68,2% dos pacientes apresentavam efluente de consistência pastosa e realizavam autocuidado. Conclusão: A prevalência de pessoas com estomia foi semelhante à de outros municípios de Minas Gerais e abaixo do esperado pelas Associações Nacional e Internacional de Ostomizados. A caracterização das pessoas, das estomias e do manejo destas contribuirá para que profissionais de saúde e gestores revisem os protocolos de assistência utilizados na microrregião estudada.

Prevalence of elimination stomas in a microregion in the north of Minas Gerais

Objectives: To estimate the prevalence of people with elimination stoma and to characterize them for sociodemographic and clinical aspects. Method: A descriptive cross-sectional study with a sample of 27 patients with elimination stomas residing in a microregion in the north of Minas Gerais, who met the inclusion criteria. The data collected were recorded in an instrument used in previous studies and analyzed using descriptive statistics. Study approved by the Ethics Committee. Results: The prevalence of people with stoma was 2.16/10.000, the sample contained 55.6% of men, 40.7% were married, mean age 59.1 years, 59.2% were literate and 74.0% had low income; 59.3% of the stomas were cancerous, more frequent colon and rectum tumours, 70.4% of the stomas were definitive, and 74.0% were colostomies. Dermatitis was the main complication and 68.2% of the patients presented effluent of pasty consistency and performed self-care. Conclusion: The prevalence of people with stoma was like that of other municipalities in Minas Gerais and below that expected by the National and International Ostomized Associations. The characterization of the people, of the stomas and the management of these, will contribute for health professionals and managers to review the assistance protocols used in the studied microregion.

Knowledge, practices and expectations of preventive care: a qualitative study of patients attending government general outpatient clinics in Hong Kong

Background

Evidence-based preventive care recommendations have been well established, but studies have persistently reported gaps between these recommendations and general practitioners’ practices in providing preventive care. Many studies have explored factors that affect the delivery of preventive care from the perspectives of the practitioners, but relatively few have evaluated the patients’ point of view. The purpose of this study was to explore patients’ understanding of preventive care, the actions they were taking in terms of preventive health and their expectations from family doctors in providing preventive care.

Methods

A qualitative study was conducted based on one-on-one in-depth interviews. Twenty-eight patients without chronic illnesses were purposively recruited from government general outpatient clinics in Hong Kong. The interviews took place between November 2013 and February 2014.

Results

The participants’ knowledge of preventive care was limited, and their preventive practices were mostly restricted to healthy lifestyle practices. They rarely obtained individualised preventive care advice from doctors. Screening investigations were initiated after symptoms had already occurred, and the decision of what to check was arbitrary. Few of the participants knew what they wanted from their doctors in terms of preventive care.

Conclusions

These findings show significant gaps between evidence-based preventive recommendations and patients’ current knowledge and practice, and show the need for a wider spectrum of preventive care education and reliable sources to provide individualised and affordable preventive assessment and screening services. Most importantly, primary care providers must take a more proactive role to provide preventive services.

Poverty and health-related quality of life of people living in Hong Kong: comparison of individuals from low-income families and the general population

Background

To assess health-related quality of life (HRQOL) among Chinese adults from low-income households in Hong Kong, and to explore any threshold of household income that impaired HRQOL.

Methods

A cross-sectional analysis was conducted on 298 adults from low-income families when they enrolled into a cohort study between 2012 and 2014. HRQOL was measured by the 12-item Short-Form Health Survey-version 2 (SF-12v2). Their mean SF-12v2 subscale and summary scores were compared with those of 596 age-sex-matched subjects randomly selected from a database of 2763 adults from the Hong Kong general population (ratio = 1:2). Multiple linear regressions were conducted to determine any association between monthly household income and HRQOL.

Results

Subjects from low-income households had significantly lower SF-12v2 bodily pain, general health, vitality and physical component summary (PCS) scores than the age-sex matched subjects from the general population. Subgroup analysis showed that a household income <50% of the median monthly household income in Hong Kong (HK$10 000 ≈ US$1290, i.e. poverty line in Hong Kong) was independently associated with poorer PCS and mental component summary (MCS) scores after adjustment for socio-demographics and co-morbidities.

Conclusion

Chinese adults from low-income households had poorer HRQOL, and <50% of the median monthly household income seems to be the threshold for impairment of both physical and mental HRQOL. The findings support the current definition of the poverty line.

A prospective cohort study to investigate parental stress and child health in low-income Chinese families: protocol paper

INTRODUCTION

Chronic stress has adverse effects on health. Adults and children from low-income families are subject to multiple sources of stress. Existing literature about economic hardship mostly focuses on either adults or children but not both. Moreover, there is limited knowledge on the relationship between parental generalised stress and child health problems. This study aims to explore the bidirectional relationship between parental stress and child health in Chinese low-income families and to identify other modifiable factors influencing this relationship.

METHODS AND ANALYSIS

This prospective cohort study will sample 254 low-income parent-child pairs and follow them up for 24 months with assessments at three time points (baseline, 12 and 24 months) on parental stress, health-related quality of life (HRQOL) and child health and behaviour using both subjective measures and objective physiological parameters. This study will collect data using standardised measures on HRQOL and behaviours of children as well as on HRQOL, mental health and stress levels of parents along with physiological tests of allostatic load and telomere length. The mediating or moderating effect of family harmony, parenting style and neighbourhood conditions will also be assessed. Data will be analysed using latent growth modelling and cross-lagged path analysis modelling to examine the bidirectional effect of parental stress and child health over time. Mediation and moderation analysis will also be conducted to examine the mechanism by which the variables relate.

ETHICS AND DISSEMINATION

This study was approved by the institutional review board of the University of Hong Kong-the Hospital Authority Hong Kong West Cluster, reference no: UW 16-415. The study findings will be disseminated through peer-reviewed publications and international conferences.

Maternal mental quality of life mediates the associations between intimate partner abuse against mothers and their children's behaviours and quality of life in low-income Chinese families

PURPOSE

To explore the association between maternal intimate partner abuse (IPA) and their children's health-related quality of life (HRQOL) and behavioural problem, and to establish a mediation model and investigate the mediating role of mothers' HRQOL on this association.

METHODS

A cross-sectional study was conducted on 197 mothers of 227 children (112 boys and 115 girls) from low-income Chinese families. The mothers were asked to complete the 5-item abuse assessment screen questionnaire for the presence of IPA, the Chinese (Hong Kong) version of 12-item Short-Form Health Survey (SF-12) for their HRQOL and a structured socio-demographics questionnaire. One of the parents completed the Child Health Questionnaire-Parent Form-50 (CHQ-PF50) and the strengths and difficulties questionnaire (SDQ) to report on their children's HRQOL and behavioural problems, respectively. The mediating effect of the maternal HRQOL on the relationship between maternal IPA status and their children's behavioural problems and HRQOL was tested using Baron and Kenney's multistage regression approach and bootstrapping method.

RESULTS

Thirty-five of the 197 mothers reported IPA (17.8%). Children whose mothers had experienced IPA had lower scores in the CHQ-PF50 mental health, parental impact-emotional, family activities and family cohesion subscales, and the psychosocial summary score compared to children of mothers who reported no IPA; they also had more emotional, conduct and hyperactivity/inattention problems and higher total difficulties scores measured by the SDQ. Maternal mental HRQOL was a mediator on the relationship between maternal IPA status and their children's behavioural problems and psychosocial HRQOL.

CONCLUSION

IPA experienced by mothers had significant negative impacts on their children's HRQOL and behaviours, which was mediated by maternal mental HRQOL.
