Friendlessness and theory of mind: A prospective longitudinal study

Chronic friendlessness in childhood predicts adverse mental health outcomes throughout life, yet its earliest roots are poorly understood. In theory, developing a theory of mind (ToM) should help children gain mutual friends and one preschool study (Peterson & Siegal, 2002. Br J Dev Psychol, 20, 205) suggested a cross‐sectional connection. We therefore used a 2‐year prospective longitudinal design to explore ToM as a predictor of mutual friendship in 114 children from age 5 to 7 years after controlling potential confounds including language ability and group popularity. Confirming friendship's distinctiveness from group sociometric status, numerous group‐rejected children (53%) had a mutual friend whereas 23% of those highest in group status did not. Five‐year‐olds with a mutual friend significantly outperformed their friendless peers on a comprehensive ToM battery (basic and advanced false belief). Longitudinally, chronically friendless 7‐year‐olds (no friends at either testing time) stood out for their exceptionally poor Time 1 ToM understanding even after controlling for group popularity, age, and language skill. Extending previous evidence of ToM's predictive links with later social and cognitive outcomes, these results for mutual friendship suggest possible interventions to help reduce the lifelong mental health costs of chronic friendlessness.     

Interattitude Structure and Attitude Dynamics

Theories of attitude change have failed to identify the architecture of interattitudinal structures and relate it to attitude change. This article examines two models (a hierarchical and a spatial–linkage model) of interattitudinal structure that explicitly posit consequences for attitude change. An experiment (N= 391) was conducted that manipulated type of hierarchy (explicit versus implicit), whether the hierarchy was primed or not, and the location in the hierarchy to which a message was directed. Whereas the hierarchical model predicts only top–down influence of attitudes on each other, a spatial–linkage model predicts that linked attitudes may influence each other regardless of hierarchical position. The results support the spatial–linkage model in that interattitudinal change is constrained less by a concept's relative position in a hierarchical structure than by the concept's association with other concepts in that structure. Furthermore, within these interattitudinal structures, concepts directly targeted by a persuasive message often exhibit less attitude change than related concepts to which the focal concept appears to be linked. Finally, an explicit hierarchy of concepts appears to facilitate interattitudinal influence much more than an implicit hierarchy of concepts does; the key to this facilitation seems to be the mental accessibility of the organizational structure.     

Friends,friendlessness, and the social consequences of gaining a theory of mind

Fink, Begeer, Peterson, Slaughter, and de Rosnay (2014) conducted a prospective longitudinal study showing that theory‐of‐mind (ToM) development at school entry (mean age 5.61 years) significantly predicted friendlessness both concurrently and 2 years later. Friendlessness (defined as lacking any friendship that is mutually reciprocated) is conceptually and empirically distinct from group popularity and independently predicts adverse mental health outcomes throughout life. Here, we respond to the thoughtful commentaries by Wellman (Brit. J. Dev. Psychol, 2015; 33, 24–26), Mizokawa and Koyasu (Brit. J. Dev. Psychol, 2015; 33, 21–23), and Lerner and Lillard (Brit. J. Dev. Psychol, 2015; 33, 18–20) with a focus on three key issues, namely (a) the definition and measurement of friendship, (b) the measurement of advanced ToM development beyond the preschool years, and (c) the exciting future potential for ToM‐based training and intervention studies to combat chronic friendlessness.     

An Examination of the Interpersonal Psychological Theory of Suicidal Behavior in Physicians

Physicians are commonly reported to die by suicide more frequently than individuals in the general population. Thus far, few reasons for this elevated suicide risk have been empirically investigated. Although the interpersonal psychological theory of suicidal behavior (IPTS) has been suggested as a fruitful means of explaining physician suicidality, it has yet to be examined quantitatively. Four hundred nineteen Pennsylvania physicians were assessed on a number of demographics, as well as all components of the IPTS. Findings indicated that physician scores on IPTS components are comparable to other groups displaying increased suicidality (e.g., military populations, prior attempters). Perceived burdensomeness was a significant predictor of suicidal ideation, while thwarted belongingness predicted prior suicide attempts. Acquired capability did not distinguish between prior attempters and nonattempters. Preliminary findings indicate the IPTS may be a useful framework for understanding and predicting physician suicidality.
