Supporters of two Turkish professional basketball teams formed the sample of the study (n = 259). Spectators’ Participation Decision Scale was used to assess the factors that make participants decide to attend a match. Descriptive and Factorial MANOVA analyses were used in data analysis process and the analyses were conducted by IBM SPSS 22 package program. MANOVA results showed that there is a significant difference between attending type and factors (F (1, 212) = 2.83, p < .05), and two main effects were found between attending type variable and socialization opportunity (F (2, 215) = 7.19, p < .008). Results indicated that taking part in basketball organizations with friends is the most preferred attending type and spectators like to be with their friends in basketball matches. As a conclusion; in order to attract more spectators to the basketball venues, basketball managers should organize basketball venues in terms of spectators’ needs.
