Labelling theory
Labelling theory matters because it explains how the label 'mentally ill' can itself change a person's behaviour and identity, not just describe an existing problem. Labelling theory proposes that deviance, behaviour that breaks social norms, is not an inherent quality of an act but something conferred by how society reacts to it. For example, imagine two teenagers who both shoplift once: one is quietly cautioned by a shopkeeper, while the other is formally arrested and labelled a 'young offender' by the system. In practice, the labelled teenager is more likely to be treated differently by others and to start seeing himself through that same label, which can shape his future behaviour.
Lemert distinguished primary deviance, an initial rule-breaking act that has little effect on a person's self-concept, from secondary deviance, further deviance that occurs after a person accepts a deviant label as part of their identity. Once secondary deviance sets in, the label can become a self-fulfilling prophecy, since being treated as 'deviant' pushes the person toward further deviant behaviour, reinforcing the very label that was applied. Scheff applied this idea to psychiatry, arguing that being formally diagnosed and treated as 'mentally ill' can itself shape a person's long-term identity and behaviour, beyond the effect of the underlying symptoms. Say a patient is discharged after a first psychiatric admission and is then excluded from a job because of their diagnosis: that social exclusion can worsen their functioning independently of their original illness. In practice, clinicians should be alert that diagnosis and hospitalisation carry a social cost, the label itself, on top of any direct clinical effect.
