How does over-diagnosis in psychology affect perceptions of normal behavior?
November 13, 2024
Over-diagnosis in psychology presents several significant challenges that impact perceptions of normal behavior. Primarily, over-diagnosis can lead to the pathologization of everyday experiences, thereby altering societal perceptions of normality and health. The practice is prevalent in areas such as ADHD (4, 27), where teacher assessments may contribute to over-diagnosis due to socio-demographic biases and stereotypes (48). These practices may result in unnecessary exposure to medications, leading to perceptions of dependency or lack of resilience in what might otherwise be considered typical developmental behavior.
Financial incentives and insurance reimbursement practices further complicate the issue, potentially encouraging clinicians to diagnose patients inaccurately (1). The pressure for categorization can also create societal stigma, as observed with conditions like ADHD and autism (3, 28). Diagnoses not only label individuals but can also lead to social and self-stigmatization, influencing personal relationships and self-worth (2, 44). Additionally, inaccurate diagnoses burden healthcare systems, misguide treatment, and exacerbate misunderstandings about mental health prevalence and severity (9, 11).
The expansion of diagnostic criteria—known as "concept creep"—is another contributing factor, wherein concepts of harm and pathology progressively widen, capturing increasingly broader behaviors under clinical scrutiny (18, 35). This expansion enables a greater degree of mental experiences to be classified as disorders, contributing to public misconceptions about mental health prevalence and perceptions of normal behavior as pathological.
In summary, the over-diagnosis of mental health conditions can result in the misrepresentation of normal human experiences as clinical pathology, fostering societal mistrust and stigma while potentially leading to unnecessary treatment and care misdirection. To alleviate these issues, defining clear diagnostic parameters and promoting awareness about the consequences of over-diagnosis are critical. Moreover, enhancing training programs to encompass cultural competence and individual variability would ensure more accurate diagnostic practices, reducing the incidence of over-diagnosis and its subsequent societal impacts.
