Determination of Validity and Reliability of the Mobbing Scale for Indoor Sports Referees

Purpose of this study is to conduct validity and reliability analyses of the scale prepared for determining the mobbing of indoor sports referees, who take active duties in different classes (basketball, handball and volleyball). In order to develop the scale, a trial scale made of 31 items in likert type was prepared and applied to referees and then factor analysis method was used, which converts many variables into meaningful and independent factors in fewer number. According to the data obtained from factor analysis, the scale has a structure of 14 articles and single component. It was determined that the total variance of scale items was 43.721 and factor load was between 0.48 and 0.76. The cronbach alpha internal coefficient of consistency was computed as 0.82. Based on the values obtained from the scale it could be said that the Mobbing Scale for Indoor Sports Referees is valid and reliable.
