Motive Arousal Without Pictures? An Experimental Validation of a Hybrid Implicit Motive Test

Pictures are widely used as stimuli in implicit motive tests. Hybrid forms of such tests present pictures and declarative statements underneath pictures. Some authors have argued that explicitly declaring agreement with motive-related statements presented underneath pictures might shift the validity of such tests from capturing less implicit motives to more explicit motives. If that is the case, pictures as elicitors of implicit motives might become less relevant. Adopting the views on validity presented by Borsboom, Mellenbergh, and van Heerden (2004 Borsboom, D., Mellenbergh, G. J., &; van Heerden, J. (2004). The concept of validity. Psychological Review, 111, 1061–1071. doi:10.1037/0033-295X.111.4.1061[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and Bornstein (2011 Bornstein, R. F. (2011). Toward a process-focused model of test score validity: Improving psychological assessment in science and practice. Psychological Assessment, 23, 532–544. doi:10.1037/a0022402[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), as well as item generation theory, we investigated whether the availability of pictures in hybrid motive tests causally affects test scores. To this end, we administered the Multi-Motive Grid (MMG; Sokolowski, Schmalt, Langens, &; Puca, 2000 Sokolowski, K., Schmalt, H.-D., Langens, T. A., &; Puca, R. M. (2000). Assessing achievement, affiliation, and power motives all at once: The Multi-Motive-Grid (MMG). Journal of Personality Assessment, 74, 126–145. doi:10.1207/S15327752JPA740109[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]), as an example of a hybrid motive test, either with or without pictures to 108 participants. Results revealed that the availability of pictures had no effect on 3 out of 6 test scores. Furthermore, eliminating pictures had only inconsistent effects on correlations with a test of explicit motives. We conclude that pictures might not unanimously elicit motives in implicit motive tests that use declarative statements as response options.     

Etiological Contributions to the Covariation Between Children’s Perceptions of Inter-Parental Conflict and Child Behavioral Problems

Prior work has suggested that inter-parental conflict likely plays an etiological role in child behavior problems. However, family-level measurement of inter-parental conflict in most traditional child twin studies has made it difficult to tease apart the specific causal mechanisms underlying this association. The Children’s Perception of Inter-parental Conflict scale (CPIC) provides a child-specific measurement tool for examining these questions, as its subscales tap multiple dimensions of conflict assessed from the child’s (rather than the parent’s) perspective. The current study examined (1) the degree of genetic and environmental influence on each of the CPIC subscales, and (2) etiological contributions to the covariation between the CPIC scales and parental reports of child behavioral problems. The CPIC was completed by 1,200 child twins (aged 6–11 years) from the Michigan State University Twin Registry (MSUTR). Parents completed the Child Behavior Checklist (CBCL) to assess child internalizing and externalizing behavior problems. Multivariate models were examined to evaluate the relative contributions of genetic and environmental factors to both the CPIC scales and to their overlap with child behavioral outcomes. Modeling results indicated no significant moderation of sex or age. Significant environmental overlap emerged between the CPIC conflict properties scale and child internalizing and externalizing problems. By contrast, significant genetic correlations emerged between the CPIC self-blame scale and externalizing problems as well as between the CPIC threat scale and internalizing problems. Overall, findings suggest that the subscales of the CPIC are somewhat etiologically diverse and may provide a useful tool for future investigations of possible gene-environment interplay.
