DESIGN: Hayvaert et al.'s mixed methods research synthesis approach.
DATA SOURCES: The search process in the following databases, CINAHL, PsycINFO, and Scopus resulted in eight high-quality studies (5 qualitative and 3 quantitative) published between June 2016 and July 2021.
REVIEW METHODS: Descriptive statistics and instrument scores were provided in summary form. Themes were analysed using Krippendorff's content analysis. A joint display was provided to reveal a complementary relationship between two different data sets.
RESULTS: A total of 348 single mothers participated. Amongst the pooled sample, women identified as: Japanese (n = 174), Israeli (n = 147), Black African (n = 18), African American (n = 9), Native American (n = 5), Burundian-Australian (n = 8), UK British (n = 12), Asian (n = 3), South Korean (n = 7), Indian (n = 2), Malaysian (n = 44), Hispanic/Latina (n = 1) and Eastern European (n = 3). Four themes were identified: (1) Learning to let go of the past, (2) It takes a whole village: Importance of social support, (3) Seeking a self-reliant life: Challenges with balancing career & childcare and (4) Finding strength within: Personal growth. Only one intervention utilizing creative group counselling was found to significantly decrease depression (p = .008), anxiety (p = .005), and stress (p = .012) whilst increasing self-compassion (p = .013).
CONCLUSION: It is important for clinicians who care for single mothers, particularly if they recently immigrated, are multiparous, and an ethnic minority to encourage engagement in peer-initiated counselling and obtain mental health care as necessary.
IMPACT: This study identified and addressed the mental health issues that single mothers face worldwide. This is also the first mixed methods research synthesis to report single mothers' ethnicity in nursing and midwifery literature. Thus, findings from this mixed methods research synthesis can help nurses worldwide build culturally-concordant programs in their respective community organizations and partners (e.g. community health centres, mother-child enrichment clubs), inform health policies, and promote safer spaces for many single mothers, particularly for those who will immigrate to the Global North (i.e. UK, US, Canada) and become an ethnic minority.
