Background: This study, grounded in self-determination theory, examined how satisfaction of the needs for autonomy, relatedness and competence in people with mild to borderline intellectual disability (MBID) changed over a 4.5-year period. Additionally, it explored the association between life events across various domains (i.e. health, support and living situation, crime, relationships and freedom and finance) and these changes and explored the prospective associations between these needs, perceptions of support from direct support staff and the well-being and ill-being of people with MBID. Methods: Based on a sample of 117 adults with MBID, multiple regression analyses were conducted to determine correlations between constructs at both time points and the impact of autonomy support on need satisfaction and motivation, taking into account life events. Results: The analyses showed that, at both time points, most constructs were statistically significantly correlated and remained so despite a time lag of 4.5 years. Autonomy support emerged as a significant positive predictor, of medium size, for satisfying autonomy and relatedness needs. Its association with competence need satisfaction was not statistically significant after Bonferroni correction. For type of motivation, autonomy support statistically predicted increased autonomous motivation, irrespective of life events. Conclusions: Findings underline the potential of autonomy supportive direct support in the lives of individuals with MBID. Some unexpected null findings underscore the need for further study into the interplay between autonomy support, life events and the well-being of people with MBID.
