Friendship Quality Over Time in Youth With Spina Bifida Compared to Peers.

Objective: Examine friendship qualities (i.e., control, prosocial skills, positive affect, support, companionship, conflict, help, security, and closeness) and perceived self-efficacy in friendships of children with spina bifida (SB) and chosen peers over time through observed behaviors and self-report.

Methods: Families of children with SB (aged 8-15) were asked to invite the child's "best friend" to participate in-home assessment visits; 127 friendship dyads were included in the current study. Mixed-effects models were used to examine children with SB and their peers across age on observed behaviors and self-reported data about their friendships.

Results: For observed behaviors, peers displayed more control (p = .002) and prosocial behaviors (p = .007) with age than youth with SB. Male peers displayed higher control in their interactions as they aged (p = .04); and males with SB maintained their level of prosocial behaviors with age, compared to an increase in prosocial behaviors with age for all other groups (p = .003). For self-reported data, there was no evidence to suggest significant differences in friendship qualities across age (ps ≥ .2), with the exception of increased help (p = .002). Female peers reported increases in companionship across age compared to the other groups (p = .04).

Conclusions: Differing from previous examinations of social characteristics in SB, most longitudinal trends in friendship qualities did not differ for youth with SB compared to their peers. Promotion of this existing social strength may be a key intervention target for future strategies that promote positive outcomes for youth with SB.
