We studied the reliability of a Dutch version of the Social Support for Exercise Behaviors Scale, originally developed by Sallis, Grossman, Pinski, Patterson, and Nader, using a sample of 461 older adults between 55 and 65 years of age. Cronbach alpha for the three subscales was calculated, respectively, as .69, .71, and .26, which are lower than the alphas reported in the original study. This may be due to the cultural differences between The Netherlands and the United States and differences between the samples of the two studies.
