Parental involvement is crucial as it shapes not only childhood development but also influences long-term psychological well-being and relational patterns in adulthood. This cross-sectional study delves into the intricate dynamics between parental involvement during childhood, adult attachment styles, and depression among a diverse sample of 120 adults aged 18 and above. Participants were recruited through various channels and administered the Parental Involvement Scale (PIS), Adult Attachment Scale (AAS), Beck's Depression Inventory (BDI), and a demographic form. Through rigorous data analysis, including correlation techniques, significant associations emerged, shedding light on the complex interrelationships among these variables. The findings underscore the enduring impact of parental involvement on adult attachment styles and mental health outcomes, emphasizing the importance of early familial influences in shaping individual psychological well-being. Nature of human development, informing future research endeavors and intervention strategies aimed at promoting healthy attachment patterns and mitigating depressive symptoms in adulthood are studied.
