Results: As a group, the participants experienced statistically significant improvements in time (x 2 = 144.25, px 2 = 38.00, px 2 = 207.08, pZ = -8.50, pd = 0.92), frequency (Z = -4.07, pd = -2.60), and level of assistance (Z = -9.39, pd = -2.44). Results calculated for individual participant performance mirrored group results. Conclusion: The findings of this study suggest that the intervention effectively improved the participants' shopping performance. Further research is warranted. Comments The authors report no potential conflicts of interest.
