    The General Health Questionnaire (GHQ) effectively identifies minor psychiatric disorders in primary care. Early detection and treatment significantly shorten the duration of psychiatric episodes, improving patient outcomes.

    Area of Science:

    • Psychiatry
    • General Practice
    • Public Health

    Background:

    • Minor psychiatric disorders are prevalent in primary care settings.
    • Early identification and intervention are crucial for effective secondary prevention.
    • The General Health Questionnaire (GHQ) is a screening tool for psychiatric disorders.

    Purpose of the Study:

    • To evaluate the efficacy of the General Health Questionnaire (GHQ) in secondary prevention of minor psychiatric illness.
    • To assess the impact of case detection and treatment on psychiatric disorder duration in primary care.
    • To compare outcomes for treated and untreated groups with hidden psychiatric disorders.

    Main Methods:

    • Screening of 1093 consecutive general practitioner attenders using the GHQ.

  • Random assignment of patients with hidden disorders into treated and untreated control groups.
  • Assessment of disorder duration and consultation rates over one year.

    • Main Results:

    • 32% of patients had conspicuous and 11% had hidden psychiatric disorders.
    • Case detection and treatment led to immediate and beneficial effects, shortening episode duration.
    • Significant differences in outcomes were observed for more severe disorders at one year.
    • Mild disorders showed spontaneous recovery or later manifestation and treatment.
    • The 'detected' group showed increased consultations for emotional complaints but not overall consultation rates.

    Conclusions:

    • The GHQ is effective for identifying minor psychiatric disorders in primary care.
    • Early detection and treatment via GHQ screening improve patient outcomes by reducing disorder duration.
    • While beneficial for all, the impact is more pronounced for patients with severe psychiatric disorders.
