Effect of personal disclosure and mutual sharing intervention on cohesion in sports teams

The aim of this thesis is to examine the effects of the Personal Disclosure and Mutual Sharing (PDSM) intervention program, which is based on communication, on engagement in sports teams. A total of 78 players from 8 teams [Volleyball (n=6), Basketball (n=2)] aged between 13-19 years, playing at junior and star levels were included in the study. Scale for Effective Communication in Team Sports (SECTS) and the The Youth Sport Environment Questionnaire (YSEQ) were used to measure communication and cohesion variables. In the current study, the experimental condition received a seven-session PDSM intervention, while the control condition did not. According to the findings of the repeated measures Multivariate Analysis of Variance (MANOVA), the Distinctiveness and Negative Conflict subscale scores decreased in the experimental group , while they increased in the control group. There was a statistically significant increase in the experimental group in the Task Cohesion sub-dimension. The scores show that the intervention program had a positive effect on reducing the negative aspects of communication in sports teams and increasing task cohesion in teams.
