    Abstract:
    AIMS: We investigate reasons for persistent medication refusal in schizophrenia spectrum disorders and test whether factors that speak for a rational decision, such as negative experiences with medication or low symptom distress predict medication refusal, even after taking differences in insight into account. METHOD: We included 45 participants with schizophrenia spectrum disorders, of which 20 had refused antipsychotic medication for at least three months and assessed reasons for taking or not taking medication, labeling condition as mental disorder ("insight"), experiences with the previous treatments, symptoms and symptom distress, positive and negative consequences and experiences of psychosis, causal beliefs, therapeutic relationships with previous clinicians and attitudes towards medication. RESULTS: Groups did not differ in symptom severity but medication refusers reported significantly less insight, less satisfaction with their most-recent psychiatrist and with previous medication, and more negative beliefs about harmful effects of medication. They also felt less informed about medication. After controlling for insight, the perceived helpfulness of the previous treating psychiatrist (OR=0.30, z=5.58, p=0.018) and of previous medication (OR=0.27, z=6.87, p=0.009) and feeling insufficiently informed about medication (OR=0.53, z=3. 85, p=0.050) significantly predicted medication discontinuation. CONCLUSIONS: Building rapport with patients with a different view of the nature of their condition and encouraging informed decisions on medication are likely to improve medication adherence. However, the findings also suggest that refusing medication after a phase of initial adherence is also the consequence of negative experiences with medication and could result from weighing the pros against the cons.
