Item Open Access Published version Peer-reviewed Developmental Aspects of Schizotypy and Suspiciousness: a Review.(Springer Science and Business Media LLC, 2018) Wong, Keri K; Raine, Adrian; Wong, Keri [0000-0002-2962-8438]PURPOSE OF THE REVIEW: This review identifies the early developmental processes that contribute to schizotypy and suspiciousness in adolescence and adulthood. It includes the most recent literature on these phenomena in childhood. RECENT FINDINGS: The early developmental processes that affect schizotypy and paranoia in later life are complex. In contrast to existing studies of psychiatric patients and clinical/nonclinical adult populations, the study of schizotypy and suspiciousness in young children and adolescents is possible due to new child-appropriate dimensional assessments. New assessments and the advancement of technology (e.g., virtual reality in mental health) as well as statistical modeling (e.g., mediation and latent-class analyses) in large data have helped identified the developmental aspects (e.g., psychosocial, neurocognitive and brain factors, nutrition, and childhood correlates) that predict schizotypy and suspiciousness in later life. SUMMARY: Prospective longitudinal designs in community youths can enhance our understanding of the etiology of schizophrenia-spectrum disorders and, in the future, the development of preventive interventions by extending adult theories and interventions to younger populations.Item Open Access Suspiciousness(Springer International Publishing, 2017-09-01) Wong, KK; Zeigler-Hill, V; Shackelford, TK; Wong, Keri [0000-0002-2962-8438]Paranoia, or persecutory delusions, is a quintessential symptom of psychotic disorders such as schizophrenia. Individuals suffering from paranoid ideations become increasingly isolated, avoidant of social situations, and unhappy. These unfounded fixed suspicions that others are out to harm the individual exist on a continuum of severity across clinical and community populations, with 1–3% of nonclinical populations having delusions of clinical severity, a further 5–6% having a delusion but of less severity, and 10–15% reporting regular paranoid thoughts. This dimensional approach has recently been applied to children and to groups from different countries. Much progress has been made on the causes and treatments of paranoia, and these remain significant areas of research and clinical interest. Understanding paranoia and its correlates developmentally continues to be critical to our understanding of the etiology of schizophrenia-spectrum disorders.
