Design and Implementation of a Carer Aromatherapy Training (CAT) Program for Children With Global Developmental Delay in Hong Kong: A Mixed Qualitative Study Using the COM-B Framework

Overview

This project aims to design and implement a Carer Aromatherapy Training (CAT) program, guided by the Capability, Opportunity, Motivation and Behaviour (COM-B) model, to empower carers with safe and effective aromatherapy practices. Methods This study will employ a mixed-methods approach to explore behavioural changes and the experience of adopting the CAT programme among parents of children with physical disabilities in Hong Kong. Around 30 carers (preferably parents) of children with global developmental delay from different districts of Hong Kong will be recruited to participate in CAT Program. Following participants' consent to participate, a a one-day (8-hour) face-to-face training program will be given to carers being recruited in the study. One session of introduction will be given to staffs by certified IFPA aromatherapy nurse in centres on the first session of training programme for introducing the theories of aromatherapy, the possible benefit behind and safety issues they must be aware of. Afterwards, massage sessions will be demonstrated with standardised effleurage, on abdomen and four limbs and return demonstrated. After the training program, each carer is required to provide a 4-week aromatherapy massage to his/her child (twice per week for around 10-15 minutes). Qualitative data will be collected from semi-structured interviews and focus groups with questions set based on COM-B framework. Quantitative data will be collected through pre- and post-training surveys and analysed using descriptive statistics and t-test to measure changes in carers motivation and behaviour before and after the CAT programme intervention. Expected Outcomes and implications Integration of findings will provide a comprehensive understanding of the training's impact. The study is expected to demonstrate that behaviourally-informed training can improve care delivery, to strengthen workforce resilience and improve care quality.

Purpose Global developmental delay (GDD) involves significant delays in two or more developmental domains and affects approximately 1-3% of children under the age of 5 years worldwide.The causes of Global Developmental Delay (GDD) are often unknown; however, when identified, they are most commonly associated with genetic factors such as chromosomal abnormalities, single-gene disorders, or copy number variations. Study Designs The Capacity, Opportunity and Motivation Behaviour (COM-B) model will be used to design and implement a Carer Aromatherapy Training (CAT) program. COM-B model is a theoretical framework for understanding and supporting behaviour change, consisting of six components that are hypothesised to drive behaviour change, namely capacity (physical capability and psychological capability), opportunity (physical opportunity and social opportunity) and motivation (reflective motivation and automatic motivation). This design allows for a comprehensive understanding of behavioural changes among carers by first identifying measurable outcomes and then exploring the underlying experiences and contextual factors. The study employed a mixed-methods approach to have a better understanding both the quantitative outcomes of behaviour change and the qualitative experiences of carers of children diagnosed with global developmental delay in Hong Kong during and after training. Carer Aromatherapy Training (CAT) program This program aims to provide aromatherapy training to carers of children diagnosed with GDD in Hong Kong to: i) provide standard training in aromatherapy for carers of children diagnosed with GDD; ii) improve the interaction between carers and children diagnosed with GDD; and iii) explore the changes in carers' capability, opportunity and motivation to use aromatherapy in daily care routines. Following participants' consent to participate, a a one-day (8-hour) face-to-face training program will be given to carers being recruited in the study. The program will be held in activity rooms of Special Child Care Centres (SCCC) or classrooms. It consists of three modules: (1) Introduction of aromatherapy massage with safety concerns, (2) demonstration of massag steps and (3) return demonstration. One session of introduction will be given to staffs by certified IFPA aromatherapy nurse in centres on the first session of training programme for introducing the theories of aromatherapy, the possible benefit behind and safety issues they must be aware of. Afterwards, massage sessions will be demonstrated with standardised effleurage, which mould our hands to the shape of the body being massaged on abdomen and four limbs and return demonstrated. Massage oil with the mixture of Petitgrain Mandarin (Citrus reticulate) essential oil and fractionated coconut carrier oil will be used. After the training program, each carer is required to provide a 4-week aromatherapy massage to his/her child (twice per week for around 10-15 minutes). Incentive to participants To increase the compliance and incentive of participants to complete the whole training program, HK$150 supermarket coupon will be given to each carer who finished the whole program and focus group interview for investigating the adaptation of CAT programme and a job satisfaction questionnaire. After the training program, each carer is required to provide a 4-week aromatherapy massage to his/her child (twice per week for around 10-15 minutes). Qualitative data from semi-structured interviews and focus groups with questions set based on COM-B framework will be audio-recorded, transcribed verbatim and organized using field notes with the help of Nvivo 12. Quantitative data will be collected as the parental stress level using the Chinese version of the Parenting Stress Index (PSI-SF) (4th version) through pre- and post-training surveys and analysed using descriptive statistics and t-test to measure changes in carers motivation and behaviour before and after the CAT programme intervention. Expected Outcomes and implications Integration of findings will provide a comprehensive understanding of the training's impact. If the programme is effective, carers will gain improved capability through targeted training, leading to greater confidence in delivering person-centred care. Besides, by addressing motivational factors and creating supportive opportunities, carers can reduce parental stress and burnout as well as improving wellbeing of both carers and children with physical disability. For the population, children with physical disability will benefit from more consistent, empathetic, and responsive care, which can enhance their overall health, wellbeing, and dignity.
