Cascade training for scaling up care for perinatal depression in primary care in Nigeria.

Background: Task-shared care is a demonstrated approach for integrating mental health into maternal and child healthcare (MCH) services. Training and continued support for frontline providers is key to the success of task sharing initiatives. In most settings this is provided by mental health specialists. However, in resource constrained settings where specialists are in short supply, there is a need to explore alternative models for providing training and supportive supervision to frontline maternal care providers. This paper reports on the impact of a cascade training (train-the-trainers) approach in improving the knowledge and attitudes of primary healthcare workers (PHCW) to perinatal depression.

Methods: Senior primary health care providers selected from across participating local government areas were trained to provide training to other PHCWs. The training sessions facilitated by these trainers were observed and rated for fidelity by specialist trainers, while the trainees provided their impression of and satisfaction with the training sessions using predesigned assessment forms. Training outcomes assessed included knowledge of depression (using mhGAP training questions and knowledge of depression questionnaire) and attitude towards providing care for depression (revised depression attitude questionnaire (R-DAQ)) measured pre and post training as well as six months after training.

Results: Trainees were 198 PHCWs (94.4% female), who routinely provide MCH services in 28 selected primary care clinics and had between 6- and 34-years' experience. Training was provided by 11 trained trainers who were general physicians or senior nurses. Training sessions were rated high in fidelity and on training style. Sessions were rated excellent by 77.8% of the trainees with the trainers described as knowledgeable, effective and engaging. Knowledge of depression mean score improved from a pre-training level of 12.3 ± 3.5 to 15.4 ± 3.7, immediately post-training and 14.7 ± 3.2, six months post-training (both comparisons: p < 0.001). The proportion of PHCW workers endorsing statements indicative of positive attitudes on the professional confidence and the generalist perspective modules of the R-DAQ also increased with training.

Conclusion: Our findings suggest that cascade training can be an effective model for rapidly providing training and upskilling frontline PHCWs to deliver care for women with perinatal depression in resource limited settings.
