INTRODUCTION: Insecure attachment styles are associated with mental health problems and may influence reality perception. This study investigated the link between attachment styles and reality-testing impairment in individuals with schizophrenia. A cross-sectional survey with 200 participants diagnosed with schizophrenia assessed their attachment styles (Psychosis Attachment Measure) and reality-testing abilities (Bell Reality Testing Inventory). A significant positive correlation emerged between insecure attachment and poorer reality testing (r = .394, p < .001). Avoidant attachment was most prevalent (mean scores: 17.01, SD = 3.71), followed by anxious attachment (16.53, SD = 4.20). Reality-testing impairment manifested across all three domains: uncertainty of perception (7.16, SD = 2.45), reality distortion (3.52, SD = 1.21), and hallucinations/delusions (26.63, SD = 5.83). Interestingly, specific demographics (male, unmarried, 40-50 years old) and those with a duration of illness of less than 5 years had higher mean scores (27.35, SD = 5.61). Insecure attachment styles, notably anxious and avoidant, are dominant among clients with schizophrenia, who also struggle with reality distortion, perceptual uncertainty, and hallucinations/delusions in all three domains. Healthcare providers and nurses should understand the psychological dynamics of clients with insecure attachment styles to establish effective therapeutic relationships. A secure, structured, and consistent environment is vital to modifying insecure attachment styles and promoting reality orientation. Secure Attachment Style Oriented Psycho-Educational Program, Mentalization, Cognitive Interpersonal Therapy, and Cognitive Analytic Therapy can help reduce reality-testing impairment. Fostering Maternal and Child Health (MCH) centers on empathizing secure bonds between mothers (and mothers-to-be) and their children to promote healthy attachment styles as a preventive measure.
