Seven preregistered experimental studies investigated a potential mediator (self-blame) and moderator (the perceived responsibility of the helper for the help recipient's behavior) of Weiner's attribution-emotion-action model. When participants considered a nonchild close other experiencing depression, higher perceived controllability was related to lower sympathy, which correlated with less willingness to provide support; however, among parents considering their child experiencing depression, perceived controllability was either positively associated with sympathy (study 1) or did not influence sympathy (study 2). Offering an explanation, studies 3a/3b indicated a significantly weaker relationship between controllability and responsibility attributions when the target of help was the participant's child. Study 4 investigated the underlying mechanism. Parents experienced self-blame when the cause was controllable, which lowered the association between controllability and responsibility attributions. Studies 5 and 6 revealed this pattern was not specific to the parent-child relationship but occurred whenever the potential helper felt responsible for the help recipient's behavior.
