BACKGROUND: The Maslow's hierarchy of needs (Maslow's pyramid) and the Mental Health and Psychosocial Support (MHPSS) pyramid are integral frameworks in humanitarian settings whose aim is to address individual and community needs. However, confusion often arises among non-governmental organization (NGO) workers about the application and differentiation of these models. AIM: This study aims to investigate the extent of confusion among NGO workers in Iraq as regards the Maslow's and MHPSS pyramids, identify the causes of this confusion, and explore its implications in the context of humanitarian mental health support. METHODS: A pilot descriptive study was conducted in December 2023 through an online survey involving 61 local NGO workers from MHPSS components in Iraq. We created a measure to assess the participants’ familiarity with both models, their perceived differences, and their views on the models’ applicability in humanitarian contexts. RESULTS: Male participants represented 55.7% (n=34) of the sample, while females accounted for 44.3% (n=27). Most participants were aged 25–34 (57%, n=35) and 35–44 (34%, n=21). A majority held bachelor’s degrees (67.2%, n=41), with 21.3% (n=13) holding master’s degrees. In terms of occupation, 49.2% (n=30) were engaged in the protection sector (gender-based violence and child protection), followed by health (19.7%, n=12), education (4.9%, n=3), and MHPSS staff roles in other sectors (26.2%, n=16). The study revealed that 54.1% (n=33) of the participants struggled to understand or differentiate between Maslow's and MHPSS pyramids. The causes of this confusion were related to perceived structural similarities (18.03%, n=11), lack of awareness and knowledge about the MHPSS pyramid (63.93%, n=39), and a combination of both (18.03%, n=11). CONCLUSION: The study underscores the importance of better training and education for NGO workers to improve their understanding of the Maslow's and MHPSS pyramids. Addressing this knowledge gap can increase efficacy in humanitarian aid provision, ensuring that individual and community needs are adequately met in crisis situations.
