Notably, studies on high-risk...

Introduction to Psychological Disorders

1.7K
Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

    Area of Science:

    • Psychiatry and Public Health
    • Epidemiology of Mental Disorders

    Context:

    • Suicidal behavior is a significant public health concern.
    • Chile has experienced a notable increase in suicide rates between 1992 and 2009.

    Purpose:

    • To determine the prevalence of suicidal behavior in Chile.
    • To investigate the association between suicidal behavior and sociodemographic factors and psychiatric conditions.

    Summary:

    • A study of 2,978 Chilean participants using the Composite International Diagnostic Interview (CIDI) found a 14.3% lifetime prevalence of suicidal ideation and a 7.7% prevalence of suicide attempts.
    • Suicide attempts were linked to demographic factors (sex, age, education), lifestyle (smoking), relationship status, and psychiatric diagnoses including depressive disorders, dysthymia, and substance dependence.

    Impact:

    • Findings indicate that Chilean prevalence rates for suicidal behavior exceed international averages.
    • Effective intervention strategies should address mood disorders and substance use disorders concurrently with suicide prevention efforts.
