This study examined the relationship between microanalytic coding and global rating systems when coding maternal parenting behaviour in two contexts. Observational data from 55 mother--child interactions with two- to four-year-old children, in either a mealtime (clinic; N?=?20 or control; N?=?20) or a playtime context (community; N?=?15), were coded via both microanalytic and global systems. Results from the microanalytic coding and global rating demonstrated similar results, with both scales showing adequate psychometric properties. No difference was found in the sensitivity of the two systems in the control sample; however, the global method demonstrated more sensitivity in measuring behaviour in the playtime context. This finding may indicate that global ratings are more sensitive in a population with high base rates of positivity or in a playtime context. This study highlights the incongruence of different measurement methods and emphasises the importance of considering coding methodology for different types of populations.
