Internalising problems and the effects of peer ostracism on children's primary needs

The aim of this study was to examine associations between ostracism, internalising problems, and threat to primary needs (belonging, control, self-esteem, meaningful existence) in children (N = 165, M age = 9 years). Ostracism was simulated experimentally using the Cyberball paradigm - a computer-based ball-throwing game - and threats to primary needs were indexed using a modified version of the primary needs questionnaire (PNQ-C; Hawes et al., 2012). Overall, children with greater internalising problems reported greater need-threat following Cyberball. Importantly however, in the domain of 'belonging', the relationship between internalising problems and need-threat was moderated by inclusionary status. Specifically, children with high levels of internalising problems exhibited greater need-threat than children low in internalising problems when included by peers; yet following ostracism, children with high internalising problems were no longer distinguishable from those with low internalising problems in terms of threat to belonging.
