“…The obtained findings indicating the absence of significant age differences in self-efficacy are supported by the results of previous studies (Gresham et al, 1988;Payne & Jahoda, 2004). Similarly, the results which refer to sense of relatedness are consistent with the findings of other authors according to which, in persons with ID, there were no significant age differences in social skills (Adeniyi & Omigbodun, 2016;Heiman & Margalit, 1998), peer acceptance and relations (Heiman & Margalit, 1998;Wendelborg & Kvello, 2010), and perceived social support (Lunsky & Benson, 2001). In interpreting these findings, Nota and colleagues (2007) made a significant observation that the limited experiences and opportunities that hinder individual qualities of people with ID override any age-related effects.…”
