This study aimed to assess current levels of knowledge, opinions and attitudes regarding mental health among the local cohort of general practitioner trainees (n = 45) working in Malta. A questionnaire adapted from the Mental Health Literacy Scale was used. Data were analysed using one-way analysis of variance and Pearson correlation tests.

All participants had scores equal to or more than the mean score in their knowledge and confidence assessments; 51% of the participants achieved the maximum score for a very positive attitude towards mental health, with such scores found particularly among female trainees. Increased levels of knowledge are associated with a more positive attitude, which can in turn lead to greater acceptance and reduce stigma.

Knowledge is a powerful tool for reducing stigma and improving the doctor–patient relationship, indicating that regular training initiatives are necessary to equip budding general practitioner specialists with the necessary skills and confidence.

Improvements are greatest in the earlier weeks of antipsychotic treatment of patients with non-resistant schizophrenia.

To address the early time-line for improvement with antipsychotics in treatment-resistant schizophrenia.

Randomised double-blind trials of antipsychotic medication in adult patients with treatment-resistant schizophrenia were investigated (last search June 2010). A series of meta-regression analyses were carried out to examine the effect of time on the average item scores in the Positive and Negative Syndrome Scale (PANSS) or Brief Psychiatric Rating Scale (BPRS) at three or more distinct time points within the first 6 weeks of treatment.

Study duration varied from 4 weeks to 1 year and the definitions of treatment resistance as well as of treatment response were not necessarily consistent across 19 identified studies, resulting in highly variable rates of response (0–76%). The mean standardised baseline item score in the PANSS or BPRS was 3.4 (s.e. = 0.06) in the five studies included in the meta-regression analysis, with the average baseline Clinical Global Impression – Severity score being 5.2 (marked illness). For the pooled population treated with a range of antipsychotics (n = 1019), significant reductions in the mean item scores occurred during the first 4 weeks; improvements observed in later weeks were smaller and non-significant. In contrast, weekly improvement with clozapine was significant throughout (n = 356).

Our findings provide preliminary evidence that the majority of improvement with antipsychotics may occur relatively early. More consistent improvements with clozapine may be associated with a gradual titration. To further elucidate response patterns, future studies are needed to provide data over regular intervals during earlier stages of treatment.
