Life Skills Training for Anxiety and Football Performance in Adolescent Players (LST-Football)
Life Skills Training and Athletic Performance of Non-Elite Adolescent Football Players: The Mediating Role of Reduced Cognitive Anxiety
연구 개요
상세 설명
The study will use a two-arm parallel longitudinal randomized design with three assessment points: T0 at baseline, T1 immediately after completion of an eight-week intervention, and T2 four weeks after T1. Participants will be 160 non-elite football players aged 14-17 years from 16 teams. Individual randomization will be conducted within team-by-gender strata using a computer-generated random sequence, targeting 80 participants per condition.
The life skills intervention will consist of 16 sessions delivered over eight weeks (two sessions per week; 45-60 minutes per session; approximately 8-10 players per small group). Content will include goal setting, self-management, emotional regulation, problem solving, decision making, communication, teamwork, time management, coping with mistakes, and transfer of skills beyond sport. Control participants will continue usual football training without the structured life skills program during the study period. Attendance, possible control contamination, and concurrent psychological training will be recorded.
Cognitive sport anxiety will be assessed using the 15-item Sport Anxiety Scale-2. Worry will comprise items 3, 5, 8, 9, and 11; Concentration Disruption will comprise items 1, 4, 7, 13, and 15; Somatic Anxiety will comprise items 2, 6, 10, 12, and 14. Cognitive Anxiety will be defined as Worry plus Concentration Disruption. Football performance will be assessed using passing accuracy, shooting accuracy, dribbling time, and agility time. These components will be standardized using fixed baseline reference parameters, with time-based measures reverse-directed, and combined into a T-score Football Performance Index in which higher values indicate better performance.
Primary intervention effects will be evaluated with linear mixed-effects models using condition, time, and condition-by-time fixed effects, while accounting for repeated observations within participants and clustering within teams. Secondary outcome contrasts will be adjusted using the Holm procedure. The longitudinal indirect pathway will be evaluated as intervention allocation → T1 cognitive anxiety reduction → T2 football performance. The indirect effect will be estimated with 5,000 team-cluster bootstrap resamples. Sensitivity analyses will include per-protocol attendance, control contamination, concurrent psychological training, complete T2 cases, multiple imputation with 20 imputed datasets, and alternative FPI scoring.

실험적: Life Skills Training
Participants will receive a structured eight-week life skills training program consisting of 16 small-group sessions delivered twice weekly.
Each session will last 45-60 minutes and will involve approximately 8-10 players.
Training will address goal setting, self-management, emotional regulation, problem solving, decision making, communication, teamwork, time management, coping with mistakes, and transfer of skills beyond sport.

An eight-week behavioral life skills program delivered in 16 small-group sessions (2 sessions/week; 45-60 minutes/session; approximately 8-10 players/group).
The program will include goal setting, self-management, emotional regulation, problem solving, decision making, communication, teamwork, time management, coping with mistakes, and transfer of skills beyond sport.
Attendance will be recorded.
Per-protocol adherence will be defined as attendance at ≥80% of sessions (at least 13 of 16 sessions).

간섭 없음: Usual Training Control
Participants will continue their usual football training during the eight-week study intervention period and will not receive the structured life skills training program.
Potential exposure to intervention content and concurrent psychological training will be monitored.

Change in Cognitive Anxiety Score
기간: Baseline (T0), immediately post-intervention at 8 weeks (T1), and 4-week post-intervention follow-up (T2; approximately 12 weeks after baseline)
|
Cognitive Anxiety will be calculated as the sum of the Worry and Concentration Disruption subscales of the 15-item Sport Anxiety Scale-2.
Each subscale contains five items scored from 1 to 4; therefore the Cognitive Anxiety composite will range from 10 to 40, with lower scores indicating less cognitive sport anxiety.
The primary analysis will evaluate differential change between groups over time.

Change in Baseline-Referenced Football Performance Index
기간: Baseline (T0), immediately post-intervention at 8 weeks (T1), and 4-week post-intervention follow-up (T2; approximately 12 weeks after baseline)
|
The Football Performance Index will combine passing accuracy, shooting accuracy, dribbling time, and agility time.
Each component will be standardized using fixed baseline reference parameters; dribbling and agility time will be reverse-directed so higher standardized values represent better performance.
The composite will be transformed to a T-score metric, with higher scores indicating better football performance.
