Purpose of the Study:

  • To describe the current landscape of addiction diagnosis and treatment in Spain.
  • To investigate the prevalence and patterns of psychiatric comorbidity (dual diagnosis) among addiction patients.
  • To explore factors associated with comorbidity and current treatment approaches.

  • Statistical analysis to identify relationships between variables.

    • Main Results:

    • 33.8% of patients presented with a dual diagnosis, most commonly depression (21.6%) and anxiety disorders (11.7%).
    • Comorbidity was linked to age, gender, marital status, and education level. Alcohol and drug abuse showed higher comorbidity rates than opiate addiction.
    • Treatment setting, medical specialty, and region did not influence comorbidity rates. Antidepressants were the most prescribed medication for comorbid patients.

    Conclusions:

    • Comorbidity is a significant clinical issue in Spanish addiction treatment services, impacting one-third of patients.
    • Affective and anxiety disorders are the most frequent comorbid conditions.
    • Dual diagnosis management is essential, with no significant variations observed across different healthcare settings or professional backgrounds.
