The main purpose of the study was to evaluate a psychological skills training intervention at group level aiming to prevent injuries, separated in traumatic and overuse, in male and female elite floorball players.
Twenty-three teams in the premiere leagues for males and females were volunteered, and the teams were allocated to an intervention group (n = 11, males n = 94, females n = 99) and a control group (n = 12, males n = 109, females n = 99). The teams in the intervention group participated in a psychological skills training programme consisting of six meetings with each team. The control group received no substitute. All injuries were registered and documented according to the time-loss definition and classified into either traumatic or overuse.
In total, 142 players (35 %) out of the 401 players sustained 197 injuries, 0.49 injury/player: in the intervention group 0.45 injury/player and in the control group 0.53 injury/player. The analyses revealed no significant differences in injuries between intervention groups and control groups. The effect size of the influence of the psychological skills training in overuse injuries was considered to be small, Cohen's d 0.2.
This study comprised the whole team for a group intervention and did not screen for at-risk athletes, e.g. scoring high in anxiety or low in coping skills, which might have influenced the result. A psychological injury prevention intervention forward to a whole team might not influence the injury occurrence significantly. Thus, this psychological intervention decreased the injury incidence which is of clinical interest.

本研究的主要目的是评估一项针对男女精英地板球运动员的团体心理技能训练干预措施，该干预旨在预防创伤性和过度使用性损伤。
男女顶级联赛中的23支队伍自愿参与，这些队伍被分为干预组（n = 11，男性n = 94，女性n = 99）和对照组（n = 12，男性n = 109，女性n = 99）。干预组的队伍参加了一个心理技能训练项目，该项目包括与每支队伍进行六次会面。对照组未接受替代干预。所有损伤均根据失能定义进行登记和记录，并分为创伤性或过度使用性损伤。
401名运动员中共有142名（35%）遭受了197次损伤，每名运动员损伤0.49次：干预组每名运动员损伤0.45次，对照组每名运动员损伤0.53次。分析显示干预组和对照组在损伤方面无显著差异。心理技能训练对过度使用性损伤影响的效应量被认为较小，科恩d值为0.2。
本研究对整个团队进行了团体干预，未对有风险的运动员进行筛选，例如焦虑得分高或应对技能得分低的运动员，这可能影响了结果。对整个团队进行的心理损伤预防干预可能不会显著影响损伤的发生。因此，这种心理干预降低了损伤发生率，这具有临床意义。
