The deviation from social norms definition of abnormality

Every society operates with a set of unwritten rules or norms that guide acceptable behaviour. When individuals behave in ways that contradict these norms, their actions are considered abnormal. This definition helps distinguish between behaviours deemed desirable and those seen as undesirable, often labelling those who stray from societal expectations as social deviants. It also justifies interventions to support individuals or protect society.

Key aspects of deviation from social norms

• Contextual variation - Norms differ across cultures, situations, ages, and genders, meaning behaviour acceptable in one setting may be viewed as abnormal in another.
• Degree of deviation - The extent to which a behaviour violates a norm, and the importance society places on that norm, determines whether it is classified as abnormal.

Strengths of this definition

• Guidance on behaviour - Social norms provide a framework for understanding acceptable conduct in various contexts, making it easier to evaluate whether a behaviour is appropriate.
• Protection and support - This approach enables interventions that safeguard society from the negative impacts of abnormal behaviour while offering help to those who may not be able to help themselves.

Weaknesses of this definition

• Subjectivity of norms - Social norms are often shaped by the views of dominant groups rather than the majority, potentially being used to control or suppress those perceived as threats to social order. Non-conformists may simply be individualistic or eccentric, not abnormal.
• Changing standards - Norms evolve with societal attitudes and moral values, making them an unstable basis for defining abnormality. For instance, behaviours once classified as abnormal, such as homosexuality, have been re-evaluated over time and are no longer listed as disorders in modern classifications.

The failure to function adequately definition of abnormality

This definition identifies abnormality based on an individual's inability to manage everyday life. When behaviour disrupts personal functioning, such as maintaining work or relationships, it is considered abnormal. This approach emphasises personal distress and the lived experience of mental health challenges.

Features of personal dysfunction

Rosenhan and Seligman (1989) outlined seven characteristics that indicate personal dysfunction. The more of these features a person exhibits, the more likely they are to be classified as abnormal.

• Personal distress - A central sign of abnormality, often seen in conditions like depression or anxiety.
• Maladaptive behaviour - Actions that prevent achieving life goals, whether social or occupational.
• Unpredictability - Behaviours that are sudden or uncontrolled, such as unexpected reactions to minor setbacks.
• Irrationality - Behaviours that lack logical explanation or reasoning.
• Observer discomfort - Actions that cause unease or discomfort to those witnessing them.
• Violation of moral standards - Behaviours that go against societal ethical norms.
• Unconventionality - Displaying behaviours that are outside typical societal expectations.

Assessment tool

Clinicians often use the Global Assessment of Functioning Scale (GAF) to evaluate an individual's level of social, occupational, and psychological functioning, providing a measurable way to determine the severity of dysfunction.

Strengths of this definition

• Measurable assessment - The GAF offers a continuous scale to gauge the extent of abnormality, helping clinicians prioritise those in need of psychiatric support.
• Observable focus - By concentrating on visible behaviours, this definition provides a practical checklist for individuals and others to assess levels of functioning.

Weaknesses of this definition

• Not always dysfunctional - Some individuals with harmful conditions, such as certain personality disorders, may appear to function normally despite posing risks to others.
• Subjective interpretation - The features of dysfunction can be subjective, and tools like the GAF may not fully account for an individual's personal perspective. For example, what seems abnormal to one person, like wearing bold clothing, may be normal for someone with a different personality.

The deviation from ideal mental health definition of abnormality

This approach views mental health similarly to physical health, defining abnormality as a lack of psychological well-being. Any shortfall from an ideal state of mental health suggests abnormality, focusing on positive traits rather than negative ones.

Characteristics of ideal mental health

Jahoda (1958) proposed six key traits that indicate normality. The absence of these traits, or the degree to which they are not met, points to abnormality.

• Positive attitude towards oneself - Possessing self-respect and a healthy self-concept.
• Self-actualisation - Achieving personal growth and reaching one's full potential.
• Autonomy - Being independent and capable of making decisions without reliance on others.
• Resisting stress - Having strategies to manage anxiety and cope with daily challenges.
• Accurate perception of reality - Viewing the world realistically and without distortion.
• Environmental mastery - Being adaptable and competent in handling life's varying demands.

Strengths of this definition

• Positive outlook - Unlike other definitions, this one focuses on achievements and desirable traits rather than distress or failure, promoting an optimistic view of mental health.
• Goal setting - It highlights areas for improvement, enabling individuals to set personal targets for growth and work towards normality.

Weaknesses of this definition

• Unrealistic standards - Most people fail to meet all these ideals consistently, meaning this definition might label the majority as abnormal. These criteria may represent aspirations rather than realistic benchmarks.
• Measurement challenges - Many of these characteristics are vague and hard to quantify, making objective assessment of mental health difficult.

The statistical infrequency definition of abnormality

This definition classifies behaviours as abnormal if they are statistically rare within a population. Using the concept of normal distribution, it identifies individuals who fall outside the typical range of characteristics or behaviours as abnormal.

Understanding normal distribution

Normal distribution is often represented as a bell-shaped curve, where most people cluster around the average (mean) for a given trait or behaviour. The further from the mean, the fewer individuals exhibit those characteristics. Typically, those outside approximately 5% of the population (two standard deviations from the mean) are considered abnormal.

Strengths of this definition

• Objective approach - Once a cut-off point for rarity is established, this method provides an impartial way to identify abnormality, free from personal bias.
• Relevant in specific cases - It can be useful for certain conditions, such as intellectual disability, where rarity aligns with clinical definitions of abnormality.

Weaknesses of this definition

• Ambiguity in deviation - It remains unclear how far a behaviour must stray from the norm to be considered abnormal, especially for disorders like depression, which vary widely in severity.
• Misleading frequency - Some common behaviours, such as experiencing depression (affecting around 10% of people at some point), are frequent but still considered abnormal, challenging the reliability of this definition.

Cultural relativism and its impact on defining abnormality

Cultural relativism refers to the idea that what is considered 'normal' varies across different cultures, and each perspective is equally valid. This concept significantly influences how abnormality is defined and diagnosed.

Cultural considerations in definitions of abnormality

• Variation in social norms - Social expectations differ within and between cultures, complicating the identification of when norms are breached. Diagnoses often reflect the norms of the majority culture, which can lead to over-representation of ethnic minorities in abnormal classifications.
• Cultural differences in functioning - What is seen as adequate functioning or ideal mental health varies culturally. For instance, autonomy is highly valued in individualistic societies but less so in collectivist ones.
• Statistical norms and culture - Judging individuals by the statistical norms of a different culture can be problematic, as what is rare or common differs across cultural contexts.

This highlights the importance of considering cultural backgrounds when applying definitions of abnormality to avoid misdiagnosis or bias.
