"What drives self-affirmation effects? On the importance of differentiating value affirmation and attribute affirmation": Retraction of Stapel and van der Linde (2011)

Reports the retraction of "What drives self-affirmation effects? On the importance of differentiating value affirmation and attribute affirmation" by Diederik A. Stapel and Lonneke A. J. G. van der Linde ( Journal of Personality and Social Psychology, 2011[Jul], Vol 101[1], 34-45). This retraction follows the results of an investigation into the work of Diederik A. Stapel (further information on the investigation can be found here: https://www.commissielevelt.nl/). The Levelt Committee has determined data supplied by Diederik A. Stapel to be fraudulent. His co-author was unaware of his actions and was not involved in the collection of the fraudulent data. (The following abstract of the original article appeared in record 2011-06457-001.) In a series of studies, it is demonstrated that different types of self-affirmation procedures produce different effects. Affirming personally important values (value affirmation) increases self-clarity but not self-esteem. Affirming positive qualities of the self (attribute affirmation) increases self-esteem but not self-clarity (Study 1). As a consequence, attribute affirmation (which increases self-esteem) is more effective than value affirmation as a buffer against self-depreciating social comparison information. Attribute-affirmed participants more readily accept the self-evaluative consequences of threatening upward social comparisons than do value-affirmed participants (Study 2). However, value affirmation (which increases self-clarity) is a more effective buffer against dissonance threats. Value-affirmed participants showed less attitude change after writing a counterattitudinal essay than attribute-affirmed participants (Study 3).
