The reliability of measurement instruments underpins empirical research in psychology and psychiatry. As McNeish highlighted [1], our field’s persistent overreliance on Cronbach’s α as the default reliability metric persists despite the availability of superior alternatives. This letter presents a comprehensive argument for adopting more sophisticated reliability coefficients, particularly McDonald’s Omega (ω), to strengthen psychosomatic and mental health research.
