Outcome Measures

Primary Outcomes (17)

  • Reach as measured by absolute number and proportion of individuals who participate

    Reach outcomes will be: Proportion of eligible stakeholders that register to use the app (players, coaches, club administrators, caregivers), consent to participate (coaches, club administrators), attend online education (coaches, club administrators), and/or respond to a questionnaire (players, coaches, club administrators).

    9-month follow-up

  • Effectiveness as measured by risk perception

    Risk perception (overall injury risk) is measured on a 7-point rating scale (from extremely low to extremely high) aligned with the Health Action Process Approach (HAPA) (players, coaches, club administrators)

    9-month follow-up

  • Effectiveness as measured by outcome expectancies

    Outcome expectancies (how preventable injuries are) is measured on a 7-point rating scale (from extremely not preventable to extremely preventable) aligned with the Health Action Process Approach (HAPA) (players, coaches, club administrators)

    9-month follow-up

  • Effectiveness as measured by perceived effectiveness

    Perceived effectiveness (whether intervention has improved condition/behavior) is measured on a 5-point rating scale (from strongly disagree to strongly agree) from the generic form of the theoretical framework of acceptability (TFA) questionnaire (players, coaches, club administrators)

    9-month follow-up

  • Adoption as measured by use

    Adoption is measured as having used any components and/or exercises (yes/no) (players, coaches, club administrators)

    9-month follow-up

  • Adoption as measured by affective attitude

    Affective attitude to intervention is measured on a 5-point rating scale (from strongly dislike to strongly like) from the TFA questionnaire (players, coaches, club administrators)

    9-month follow-up

  • Adoption as measured by intervention coherence

    Intervention coherence (participant understands how intervention works) is measured on a 5-point rating scale (from strongly disagree to strongly agree) from the TFA questionnaire (coaches, club administrators)

    9-month follow-up

  • Adoption as measured by self-efficacy

    Self-efficacy (confidence about using intervention) is measured on a 5-point rating scale (from very unconfident to very confident) from the TFA questionnaire (players, coaches, club administrators)

    9-month follow-up

  • Adoption as measured by burden

    Burden to use intervention is measured on a 5-point rating scale (from no effort at all to huge effort) from the TFA questionnaire (coaches, club administrators)

    9-month follow-up

  • Adoption as measured by opportunity costs

    Opportunity costs (whether intervention interfered with other priorities) is measured on a 5-point rating scale (from strongly disagree to strongly agree) from the TFA questionnaire (coaches, club administrators)

    9-month follow-up

  • Adoption as measured by ease of use

    Ease of use is measured on a 5-point rating scale (from strongly disagree to strongly agree) (players, coaches, club administrators)

    9-month follow-up

  • Implementation as measured by adherence

    Adherence (frequency) of using intervention (players, coaches, club administrators)

    9-month follow-up

  • Implementation as measured by fidelity to program

    Fidelity to program, i.e. the proportion and type of exercises (players, coaches)

    9-month follow-up

  • Implementation as measured by fidelity to implementation checklist

    Fidelity to implementation checklist, i.e. proportion of use (club administrators)

    9-month follow-up

  • Implementation as measured by coping planning

    Plan to deal with challenges is measured on a 7-point rating scale (from extremely disagree to extremely agree) aligned with the Health Action Process Approach (HAPA) (coaches, club administrators)

    9-month follow-up

  • Maintenance as measured by intention

    Intention to use intervention in the future is measured on a 7-point rating scale (from extremely not likely to extremely likely) aligned with the Health Action Process Approach (HAPA) (players, coaches, club administrators)

    9-month follow-up

  • Maintenance intention as measured by self-efficacy

    Maintenance self-efficacy (confidence about continuing to use intervention) is measured 7-point rating scale (from extremely not confident to extremely confident) aligned with the Health Action Process Approach (HAPA) (coaches, club administrators)

    9-month follow-up

Secondary Outcomes (1)

  • Implementation determinants

    After follow-up, approx. 10 months after study start

Study Arms (2)

I-PROTECT

EXPERIMENTAL

I-PROTECT includes physical and psychological injury prevention information and training (i.e., the intervention) and tailored support to implement it specifically developed for Swedish community youth handball.

Behavioral: I-PROTECT

Control group

ACTIVE COMPARATOR

Coaches of youth teams in the control group clubs will be offered currently available injury prevention training (i.e., "Redo för Handboll", English: "Ready for Handball"), accessible online through the Swedish Handball Federation's coach education material.

Behavioral: Control

Interventions

I-PROTECTBEHAVIORAL

I-PROTECT is based on existing research and knowledge of experts in sport medicine, sport psychology and implementation science, with the involvement of end-users throughout the process. The interdisciplinary intervention includes end-user-targeted information and injury prevention physical and psychological training, specifically tailored for youth handball. The intervention is delivered through a mobile application (I-PROTECT GO) specifically developed for the I-PROTECT project, including coach, player, club administrator, and caregiver modules. Tailored support to implement I-PROTECT is specifically developed for Swedish community youth handball.
