Background Women diagnosed with breast cancer (BC) receiving chemotherapy have reported various side effects, which adversely affect their psychological state. Evidence suggests that psychoeducational interventions (PEIs) delivered through mobile phones might effectively provide psychoeducational support for this population. However, there is a lack of evidence on Nigerian women’s perception of mobile health (mHealth) PEI, which prompted this study. Method A qualitative study was conducted among women with BC who had completed chemotherapy at two tertiary hospitals in Nigeria. Face-to-face focus group discussions were conducted at the oncology clinics. Data were collected using focus groups until data saturation was reached. Data were analyzed using thematic analysis. Results In total, 32 women were recruited, with seven focus group discussions conducted. The participants were between 22 and 75 years old and mostly diagnosed with Stage III BC. Four main themes emerged from the data analysis, including experiences of BC diagnosis and treatment phase, patients’ needs during chemotherapy, coping with chemotherapy, and perception of mHealth intervention for psychoeducational support. BC diagnosis was devastating, and psychological disturbances were experienced while receiving chemotherapy, but the participants indicated that mHealth intervention was acceptable as it could provide psychological and informational support. The suggested contents include information on chemotherapy, how to deal with the fear of chemotherapy, nutritious diet locally available, and information on exercise. Conclusion This study has shown that the participants perceived a mHealth PEI is feasible and acceptable in providing psychoeducational support for Nigerian women diagnosed with BC receiving chemotherapy. It is hoped that the unmet needs of this population will be addressed while receiving chemotherapy.

Face-to-face focus group interviews were conducted at the oncology clinics. Data were collected using a semi-structured interview guide until data saturation was reached. Data were analysed using thematic analysis. Results Thirty-two women were recruited, with seven focus group interviews conducted. The participants were between 22 and 75 years old and mostly diagnosed with Stage III BC. Four main themes emerged from the data analysis, including experiences of BC diagnosis and treatment phase, patients’ needs during chemotherapy, coping with chemotherapy and perception of mHealth intervention for psychoeducational support.

This study will help design a culturally appropriate mHealth PEI for this population.
