Social Desirability in Intimate Partner Violence and Relationship Satisfaction Reports: An Exploratory Analysis:

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.

SCAN as an investigative tool

Scientific content analysis (SCAN) is a technique that claims to enable the detection of deception in written statements. The underlying assumption is that statements of self-experienced events differ in several ways – such as liveliness and concreteness – from imaginary statements. It is used in many countries as an investigative tool. Nevertheless, little research on the reliability and validity of the SCAN technique is available. In this paper, two studies are presented. The first study focuses on the accuracy of SCAN to detect deception by three groups of raters with a different level of experience. This study shows a lack of validity of SCAN. Study 2 investigated the inter-rater reliability as a possible explanation for the poor validity results, and found little agreement between raters in identifying SCAN criteria. Overall, results indicate that the psychometric qualities of SCAN as an investigative tool is insufficient for use in police practice.

Exploring the indirect effect of preference discrepancy on intimate partner violence

Preference discrepancy is the difference between partners’ ideal and real relationship, and is assumed to have a negative effect on the relationship. This study examines its effect on psychological and physical intimate partner violence perpetration and victimization, and hypothesizes this effect will be mediated through relationship satisfaction, communication quality and/or conflict resolution ability. A sample of 156 respondents participated in this study. Bias-corrected bootstrap analyses revealed indirect effects of preference discrepancy on psychological and physical violence victimization through conflict resolution. People with high preference discrepancy scores report lower conflict resolution abilities, and in turn, higher victimization rates. There was also a significant total effect of preference discrepancy on physical violence perpetration, suggesting high preference discrepancy increases the chance of using physical violence against one’s partner. Further investigation is thus recommended, to assess if preference discrepancy could function as an additional anchor in the prevention of IPV within couples.
