| BRIEF NAME | |||
| 1. | Developing and evaluating an intergenerational movement program for grandchildren and their grandparents using the Behaviour Change Wheel in combination with a co-creation approach. The effects of this intergenerational movement program on co-PA, physical activity, cognitive functioning, psychosocial well-being, and quality of the family relationship in grandchildren and their grandparents will be measured. | p. 1 | ______________ |
| WHY | |||
| 2. | It is decided to develop an intergenerational movement program for grandchildren and grandparents to improve co-PA, physical activity, cognitive functioning, psychosocial well-being and the quality of the relationship in grandchildren and grandparents. First of all, many children and older adults do not meet the physical activity guidelines of the WHO. Secondly, this program will be developed using a co-creation approach together with a theoretical framework “Behaviour Change Wheel”, because it is really important to take needs and requirements of the target group into account and to develop an intervention in an evidence-based way. Thirdly, intergenerational programs are scarce in relatives and the quality of the family relationship between grandchildren and grandparents has not yet been investigated while doing organized activities together. Lastly, the combination of physical activity and cognitively enriched activities has never been used in intergenerational research. Therefore, developing a cognitively enriched, intergenerational movement program for grandchildren and their grandparents is innovative. | pp. 19–20 | _____________ |
| WHAT | |||
| 3. | Materials: All the variables (physical activity, cognitive functioning, psychosocial well-being and quality of the family relationship) will be measured pre (at baseline, before the start of the sessions), post (after 24 weeks, right after the RCT ends), and for the third period at follow-up (after 36 weeks). To objectively measure physical activity, grandchildren and grandparents will have to wear Axivity AX3 accelerometers (wrist of the non-dominant hand) or ActiGraph wGT3X-BT (right hip). Grandparents and grandchildren also have to wear these accelerometers during certain sessions to measure the intensity of the activities that they do together. A seven-day diary will be used to study the context of co-PA. Cognitive functioning will be objectively quantified with the validated neuropsychological test battery (i.e., CANTAB) (cambridgecognition.com) using an iPad 10.2. Psychosocial well-being will be measured by several questionnaires that administer well-being indicators relevant for children and older adults. For children: PEDs-QL (Pediatric health-related Quality of Life scale). For older adults: Warwick-Edinburgh Mental Well-Being Scale (WEMWBS), Four-Dimensional Symptom Questionnaire (4DSQ), Social and Emotional Loneliness scale for Adults (SELSA). Quality of the family relationship will be measured in children with the Grandparent-grandchild Relationship Questionnaire. For older adults, this will be measured with a self-report questionnaire, based on previous investigations of Farneti & Battistelli. | pp. 16–17 | _____________ |
| 4. | Procedure: Convenience sampling will be used to recruit participants for the RCT. A first strategy will be to reach out to children via schools in the city of Ghent and contact their grandparents (via their parents). All children of the first and the second grade (class 1 till 4 of the primary school) of 2 schools will receive an information letter about the goal of the study and some explanation about the RCT. In case of too low respondents, additional schools or GRAY will be addressed. If both children and their grandparents are interested to participate (parents must ask the grandparents), they can fill in their contact information using a paper strip attached to the information letter. Of those that responded to be interested to join, the researcher will call the parents and grandparents to ask some questions to administer sociodemographic characteristics (i.e., age, gender) and inclusion criteria (i.e., language, physical, cognitive and psychological health status) of grandchildren and grandparents. Before participation in the RCT, participants will be asked to sign an informed consent. Grandchildren will need parental consent and will also be asked for an informed assent themselves; grandparents will sign an informed consent for themselves. | p. 10 | _____________ |
| WHO PROVIDED | |||
| 5. | The co-creation sessions will be led by researchers and facilitators (background in movement and sports sciences, psychology and health promotion) who will have received a training in co-creation. This information is given, because the co-creation sessions are an important element for the development of the movement program and for the intervention itself. The intergenerational movement sessions will be worked out by experts in movement and sports sciences together with organizations who work with children and older adults (MOEV, Family Sports Flanders, GRAY). The intergenerational movement sessions itself will be led by students and experts in movement and sports sciences. |
pp. 9, 13 | _____________ |
| HOW | |||
| 6. | The intergenerational movement sessions will be provided in a group. Approximately 20 to 30 grandchildren and grandparents per group will be able to participate in the sessions (but group size also depends on preferences of the participants) and 1 or 2 experts in movement and sports sciences will lead these sessions. | p. 13 | _____________ |
| WHERE | |||
| 7. | The intervention will take place in Ghent, where the researchers are situated. Depending on the preferences of grandchildren and grandparents, the sessions will take place indoor or outdoor. It will also depend on the topics and needed materials whether some sessions will take place outside or not. | p. 13 | _____________ |
| WHEN and HOW MUCH | |||
| 8. | Grandchildren and their grandparents will participate in a cognitively enriched movement program, which will be developed by themselves together with the researchers (co-creation). The preferences and needs of the target group will determine what the program will look like. A total of 12 (or 24) sessions (one/two session(s) every (two) week(s) per group will take place during 24 weeks on a preferred time during the week (e.g., Wednesday afternoon, Tuesday evening, Thursday evening…). There will be two arms, arm 1 will receive only movement activities, arm 2 will receive cognitively enriched movement activities. The content of the sessions (duration, topics, format, materials) will be refined after the pilot study. Intervention groups will receive a brochure with (cognitively enriched) movement activities they can perform at home after the follow-up measurement to create a long-term effect. This part of the checklist will be refined after the pilot study, when there is more information available about the movement sessions. | p. 16 | _____________ |
| TAILORING | |||
| 9. | If the intervention was planned to be personalised, titrated or adapted, then describe what, why, when, and how. Not applicable for this intervention. | _____________ | |
| MODIFICATIONS | |||
| 10. ǂ | If the intervention was modified during the course of the study, describe the changes (what, why, when, and how). This will be described when the RCT has ended. | _____________ | |
| HOW WELL | |||
| 11. | To assess intervention adherence and fidelity, a protocol study has been written out to think about different aspects (participants, sample size, measurement instruments) in order to reduce bias. Furthermore, providers of the intervention will have received a training or will be experts in what they have to perform. The measurement instruments that will be used during the intervention are all validated and reliable for children and older adults. | pp. 13, 16–17 | _____________ |
| 12. ǂ | Actual: If intervention adherence or fidelity was assessed, describe the extent to which the intervention was delivered as planned. This will be described when the RCT has ended. | _____________ | |
** Authors—use N/A if an item is not applicable for the intervention being described. Reviewers—use ‘?’ if information about the element is not reported/not sufficiently reported. † If the information is not provided in the primary paper, give details of where this information is available. This may include locations such as a published protocol or other published papers (provide citation details) or a website (provide the URL). ǂ If completing the TIDieR checklist for a protocol, these items are not relevant to the protocol and cannot be described until the study is complete. Note 1: We strongly recommend using this checklist in conjunction with the TIDieR guide (see BMJ 2014; 348: g1687) which contains an explanation and elaboration for each item. Note 2: The focus of TIDieR is on reporting details of the intervention elements (and where relevant, comparison elements) of a study. Other elements and methodological features of studies are covered by other reporting statements and checklists and have not been duplicated as part of the TIDieR checklist. When a randomised trial is being reported, the TIDieR checklist should be used in conjunction with the CONSORT statement (see www.consort-statement.org) as an extension of Item 5 of the CONSORT 2010 Statement. When a clinical trial protocol is being reported, the TIDieR checklist should be used in conjunction with the SPIRIT statement as an extension of Item 11 of the SPIRIT 2013 Statement (see www.spirit-statement.org). For alternate study designs, TIDieR can be used in conjunction with the appropriate checklist for that study design (see www.equator-network.org).
