This paper aims to determine if single-item (SI) needs' and values' measures have similar reliability and validity values to multi-item (MI) measures of the same constructs and thus could be substituted by sport marketers to predict internal motivating aspects of sport consumer attitudes and behavior. In addition, the authors wish to determine whether a small subset of needs and values listed in current measures are sufficient to predict sport consumer attitudes and behavior.

In this two-study design, the first study was a national sample (N = 439) comparing reliability and validity of single-item scales to multi-item scales. In the second study the authors collected data from fans and spectators of four different teams (N1 = 583; N2 = 1164; N3 = 213; N4 = 404) to determine the impact of needs and values on sport consumer attitudes and behavior.

The authors determined that in 89% of the scales, single-item measures of needs and values were just as reliable and valid as their associated multi-item measures. The authors also found that a small subset of the needs and values explain a meaningful amount of variance in sport consumer attitudes and behaviors.

The authors show that as motives for sport consumption, single-item measures of personal needs and values are equivalent to multi-item measures and not all needs and values used in previous sport research are necessary because they do not predict a meaningful amount of variance in sport consumer attitudes and behaviors. The authors identified a small number of single-item measures that practitioners can easily use in short surveys that will predict a statistically meaningful amount of variance in sport consumer attitudes and behaviors.
