Evaluability and Feasibility of the eHOOD Intervention

Evaluability and Feasibility of the eHOOD: A Multi-Component Intervention to Promote Well-being, Healthy Weight, and Lifestyle Habits Among Adolescents in Vulnerable Positions Through Gaming, Physical and Social Activities, and Education

The goal of this feasibility study is to learn how to best evaluate the eHOOD intervention of-fered to adolescents in lower secondary education with psycho-social challenges. The main questions it aims to answer are:

1. What is an appropriate evaluation design for testing the eHOOD intervention?
2. Is the evaluation design feasible in terms of outcomes, measurements, instruments, data collection procedures, and participant acceptability?
3. Is the eHOOD intervention feasible and acceptable in terms of recruitment, retention of participants, and participant satisfaction and engagement? Participants will meet once a week in 25 weeks and take part in physical activity, communal cooking and dining, education in healthy lifestyle, and online gaming with instruction in a social community with peers. They will answer questionnaires and participate in interviews at the beginning and end of the intervention and their development will be assessed by the eHOOD coach.

Intervention / Treatment

Experimental: eHOOD intervention; Participants receive the eHOOD intervention consisting of one weekly four-hour meeting for 25 weeks.

Behavioral: eHOOD; Weekly meetings are hosted by the coach and one or two local pedagogues. Each meeting contains physical activity, preparation and intake of dinner, educational sessions, and gaming with instruction. Physical activities include ball games such as football, basketball, and table tennis, fitness training, traditional children's games, and coordination and reaction training. Educational sessions include teaching healthy dietary habits, sleeping habits, and exercise habits, focusing on the importance of taking care of one's body and staying fit to perform well in gaming. Gaming sessions contain training and gaming in teams. Additionally, partic-ipants are paired in teams and are given small assignments to be performed together between the weekly meetings. Communal cooking and dining are included as social and educational activities. Participants take turns preparing and serving dinner for their peers with supervi-sion from the pedagogue.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Proportion of fully completed questionnaires.	Feasibility of evaluation design - data completeness.	Baseline to end of intervention at 25 weeks.
Proportion of participants who participate in full interviews.	Feasibility of evaluation design - data completeness.	Baseline to end of intervention at 25 weeks.
Proportion of participants for whom complete accelerometer data are collected.	Feasibility of evaluation design - data completeness.	Baseline to end of intervention at 25 weeks.
Participants' experiences with instruments and data collection procedures.	Acceptability of evaluation design. Assessed via qualitative interviews at end of intervention.	End of intervention at 25 weeks
Number of weeks from recruitment start to enough participants are recruited.	Feasibility of intervention - recruitment rate.	Start of recruitment to baseline.
Percentage of participants who attend each meeting.	Feasibility of intervention - retention of participants. Assessed via registration of par-ticipants' weekly attendance in Impactly platform.	End of intervention at 25 weeks.

Participants' satisfaction with and self-rated benefits of eHOOD.	Acceptability of intervention. Assessed via qualitative interviews at end of intervention.	End of intervention at 25 weeks.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in mental wellbeing measured with the 5-item World Health Organization Well-Being Index (WHO-5) from intervention start to end of intervention	The WHO-5 includes five items each scored from 0 to 5. Raw scores range from 0 to 25 and are multiplied by 4 to transform it to a percentage scale from 0-100, where the max score equivalent to optimal wellbeing is 100, 50-70 points are equivalent to the normal range of wellbeing, and a score under 50 points is equivalent to a wellbeing below the normal range.	Baseline to end of intervention at 25 weeks
Change in loneliness measured with the Three-Item Loneliness Scale (T-ILS) from intervention start to end of intervention	The T-ILS includes three items each scored from 1 to 3. Total scores range from 3 to 9, where 9 is equivalent to the highest level of loneliness.	Baseline to end of intervention at 25 weeks
Change in level of physical activity and sleep length and quality from intervention start to end of intervention measured with SENS Motion accelerometers mounted on participants' thighs for seven consecutive days at baseline and end of intervention	The SENS Motion accelerometers measure movement and can distinguish between different types of movement and rest. In this study accelerometer data were categorized into the fol-lowing categories: inactivity (lying/sitting), moderate-intensity activity, high-intensity activ-ity, calm sleep, restless sleep, and number of steps. For each category, daily minutes were calculated, and weekly averages were derived for each participant.	Baseline to end of intervention at 25 weeks.
Change in number of days per week eating breakfast from intervention start to end of intervention.	Composite questionnaire is sent by text message to participants for seven consecutive days at baseline and end of intervention. The item was self-constructed and contains two options (yes/no). For each participant number of days with breakfast intake per week is calculated.	Baseline to end of intervention at 25 weeks.
Change in number of days per week eating fast-food from intervention start to end of intervention.	Composite questionnaire is sent by text message to participants for seven consecutive days at baseline and end of intervention. The item was self-constructed and contains two options (yes/no). For each participant number of days with fast-food intake per week is calculated.	Baseline to end of intervention at 25 weeks.
Change in number of days per week eating fruits and/or vegetables from intervention start to end of intervention.	Composite questionnaire is sent by text message to participants for seven consecutive days at baseline and end of intervention. The item was self-constructed and contains two options (yes/no). For each participant number of days with intake of fruits and/or vegetables per week is calculated.	Baseline to end of intervention at 25 weeks.
Change in number of days per week having meals together with one's family from intervention start to end of intervention.	Composite questionnaire is sent by text message to participants for seven consecutive days at baseline and end of intervention. The item was self-constructed and contains two options (yes/no). For each participant number of days with intake of one or more meals with one's family per week is calculated.	Time frame: Baseline to end of intervention at 25 weeks.
Change in number of days per week with morning sleepiness from intervention start to end of intervention.	Composite questionnaire is sent by text message to participants for seven consecutive days at baseline and end of intervention. Morning sleepiness is used as an indicator of unmet sleep needs. The item was self-constructed and contains three options (very sleepy/a little sleepy/not sleepy). For each participant number of days with morning sleepiness per week is calculated.	Baseline to end of intervention at 25 weeks.
Change in number of days per week with use of cigarettes/e-cigarettes from intervention start to end of intervention.	Composite questionnaire is sent by text message to participants for seven consecutive days at baseline and end of intervention. The item was self-constructed and contains two options (yes/no). For each participant number of days with cigarette use per week is calculated.	Baseline to end of intervention at 25 weeks.
Change in number of days per week with use of other nicotine products from intervention start to end of intervention.	Composite questionnaire is sent by text message to participants for seven consecutive days at baseline and end of intervention. The item was self-constructed and contains two options (yes/no).
