The effect of basic psychological needs satisfaction on intrinsic regulation is moderated by hedonic and eudaimonic motives: a longitudinal investigation among youth athletes in Japan

The current study was conducted to examine the interactive effects of basic psychological needs satisfaction (BPNS), hedonic and eudaimonic motives on intrinsic regulation. To assess the causal relationship, two-wave time-lagged data collection was employed. A total of 159 youth athletes in Japan participated in online surveys twice (three-month time lag between two data points). The results indicated that the effect of BPNS on intrinsic regulation was moderated by hedonic and eudaimonic motives. Interestingly, BPNS negatively affected intrinsic regulation among youth athletes with low hedonic motives. This negative impact was further augmented when the level of eudaimonic motives was higher. Conversely, BPNS positively influenced intrinsic regulation among youth athletes with high hedonic motives. This positive impact of BPNS was more prominent when eudaimonic motives were lower. Overall, the findings suggest that when intrinsic regulation is the central concern, youth athletes should focus more on seeking enjoyment while putting self-development aside to maximize the positive impact of BPNS.
