Facilitating Effective Eating With DoddleBags: A Single-Arm Acceptability Study Of DoddleBags to Assess Impact on Self Feeding Behaviours in a Huntington's Disease Population

Overview

Primary Objectives * To assess the acceptability of using the DoddleBags feeding aid in people with HD, by using a food diary to track food intake and using semi-structured interviews to ask questions about how easy or difficult it was to use a DoddleBag for each meal compared to not using one, and learn more about the impact of using DoddleBags on self-feeding behaviours. * To review the impact of using DoddleBags during mealtimes on the weight and BMI of each participant. * To review the impact of using DoddleBags during mealtimes on episodes of choking of each participant. Secondary Objectives * To evaluate the impact of using DoddleBags on participants' attitudes towards mealtimes and eating, using a short battery of mood and eating questionnaires. * To measure how incorporating DoddleBags into mealtimes affects participants' perceived quality of life, using a short battery of mood and eating questionnaires. * To assess the acceptability of the short battery of mood and eating questionnaires within a population of people with HD.

Study Procedure * Design: Participants will be interviewed, complete questionnaires and use a food diary for a week to establish a baseline. Participants will then complete a food diary while using the DoddleBags for 11 weeks before completing the questionnaires and being interviewed again. * Methods of data collection: The study makes use of a small battery of mood and eating questionnaires, as well as two semi-structured interviews and a food diary. The following questionnaires are proposed to form the battery: * Adult Eating Behaviours Questionnaire (AEB-Q) * Eating Attitude Test (EAT-26) * HD Quality of Life Scale (HDQoL) * HD-specific Eating Questionnaire (HD-EAT) * Procedure: Participants will undergo a pre-intervention semi-structured interview with the research after completing the participants' ICF, participants will also be asked to complete the questionnaire battery. Participants, with the aid of carers if appropriate, will then be asked to complete a food diary for one week to provide a baseline of the participants' daily experiences. After this baseline week, participants will be asked to use the DoddleBags products in the preparation and execution of as many mealtimes as the participant reasonably can, while completing the food diaries for a further 11 weeks. After both 1 and 4 weeks of using the DoddleBags the study team will contact the participants to check in with how the participants are finding incorporating the DoddleBags into mealtimes. As with every contact, it should be established that the participant is still happy to participate in the study and as part of the researchers' duty of care, researchers should explore if participants would like to withdraw from the study if the participant strongly believes the participant is receiving no significant benefits from the DoddleBags. The post-intervention semi-structured interview and questionnaire battery will be completed in a study visit arranged as soon as reasonably possible, and ideally within the following week after the 11 week intervention period, to ensure the participants experiences are still fresh. After this the participants will be debriefed and participation will be considered complete. • Analysis: The semi-structured interviews will be transcribed and fed into NVivo, software designed to facilitate thematic analysis. the researchers will conduct a reflexive thematic analysis on the transcripts to identify commonalities between the responses of participants both before and after the intervention. The AEBQ, HD-EAT, and HDQoL are quantitative measures, so the researchers will use a variety of explorative quantitative analyses to analysis the pre/post-intervention differences. End of Study The study will be closed to recruitment after completion of informed consent for the final participant. The study team anticipates that participant involvement in the study will last around 12-13 weeks depending on how quickly the post-intervention semi-structured interview can be arranged at a convenient time for the participant. The study will be considered complete as a concept upon publication and submission of study results.
