The social desirability bias can be considered a two-dimensional construct, consisting of impression management and self-deception. Although social desirability is often considered a threat to the validity of intimate partner violence (IPV) reports, little is known about which dimension is most responsible for this distortion. Furthermore, it is unclear whether social desirability distorts the report of relationship satisfaction. In this study, two instruments that claim to measure social desirability are investigated on their ability to measure impression management and self-deception. Afterward, which dimension (if any) is responsible for a distortion in IPV and relationship satisfaction reports is examined. The survey consisted of the following measures: the Revised Conflict Tactics Scales for IPV, the Couples Satisfaction Index for relationship satisfaction and the Balanced Inventory of Desirable Responding, the Limited Disclosure Scale, and the Idealistic Distortion Scale for social desirability. The Limited Disclosure Scale was found to predominantly measure impression management. The Idealistic Distortion Scale did not measure social desirability well and appeared to be a bad measure for relationship satisfaction. Both the reports of IPV and relationship satisfaction were influenced by impression management, but not by self-deception. However, impression management and self-deception only accounted for a small portion of the variance in IPV and relationship satisfaction reports. These results indicate that the social desirability bias, when reporting IPV and relationship satisfaction, is a conscious process, but that its influence on IPV and relationship satisfaction reports might be overrated.
