Development and initial psychometric evaluation of the sport interference checklist

The Sport Interference Checklist (SIC) was developed in 141 athletes to assist in the concurrent assessment of cognitive and behavioral problems experienced by athletes in both training (Problems in Sports Training Scale, PSTS) and competition (Problems in Sports Competition Scale, PSCS). An additional scale (Desire for Sport Psychology Scale, DSPS) was developed to assess the degree to which athletes desire sport psychology assistance in areas that are determined to be problematic. Factor analysis of PSCS items reveals six factors (Dysfunctional Thoughts and Stress, Academic and Adjustment Problems, Injury Concerns, Lack of Motivation, Overly Confident/Critical, Pain Intolerance), accounting for 64% of the total variance. PSTS and DSPS items yield four factors (Dysfunctional Thoughts and Stress, Academic Problems, Injury Concerns, Poor Team Relationships), accounting for 59% and 63% of total variance, respectively. Scores from these scales demonstrate acceptable internal consistency and convergent and discriminative validity. Response patterns of SIC scales are not influenced by gender or athlete type.
