“…For instance, siblings who grew up in the same household have been demonstrated to provide both concordant and corroborating retrospective accounts of the family environment and abuse exposure (Bifulco et al, 1997; Brown, Craig, Harris, Handley & Harvey,_2007). However, other types of corroboration are often required, for example where siblings were separated in childhood, or where they are difficult to track down for assessment, or when they are unaware of some aspects of family adversity (e.g., hidden parental discord or secretive sexual abuse to only one child) or for example if they were very young at the time of the experience (Brown et al, 1997; Platt, 1980). Therefore, obtaining alternative corroborative accounts from older family members who were present for the majority of the target person’s childhood would be an advantage in producing valid data.…”
