The influence of primary care physicians' mental health knowledge, attitudes and self-efficacy on referrals to specialised services: findings from a longitudinal pilot trial.

Background: Training based on the Mental Health Gap Action Programme (mhGAP) is being increasingly adopted by countries to enhance non-specialists' mental health capacities. However, the influence of these enhanced capacities on referral rates to specialised mental health services remains unknown.

Aims: We rely on findings from a longitudinal pilot trial to assess the influence of mental health knowledge, attitudes and self-efficacy on self-reported referrals from primary to specialised mental health services before, immediately after and 18 months after primary care physicians (PCPs) participated in an mhGAP-based training in the Greater Tunis area of Tunisia.

Method: Participants included PCPs who completed questionnaires before (n = 112), immediately after (n = 88) and 18 months after (n = 59) training. Multivariable analyses with linear mixed models accounting for the correlation among participants were performed with the SAS version 9.4 PROC MIXED procedure. The significance level was α < 0.05.

Results: Data show a significant interaction between time and mental health attitudes on referrals to specialised mental health services per week. Higher scores on the attitude scale were associated with more referrals to specialised services before and 18 months after training, compared with immediately after training.

Conclusion: Findings indicate that, in parallel to mental health training, considering structural/organisational supports to bring about a sustainable change in the influence of PCPs' mental health attitudes on referrals is important. Our results will inform the scale-up of an initiative to further integrate mental health into primary care settings across Tunisia, and potentially other countries with similar profiles interested in further developing task-sharing initiatives.
