Posttraumatic stress disorder and retrospectively reported stressor exposure: a longitudinal prediction model

There has been recent concern about the degree to which posttraumatic stress disorder (PTSD) symptomatology influences reports of prior exposure to highly stressful life events. In this longitudinal study of 2,942 male and female Gulf War veterans, the authors documented change in stressor reporting across 2 occasions and the association between change and PTSD symptom severity. A regression-based cross-lagged analysis was used to examine the relationship between PTSD symptom severity and later reported stressor exposure. Shifts in reporting over time were modestly associated with PTSD symptom severity. The cross-lagged analysis revealed a marginal association between Time 1 PTSD symptom severity and Time 2 reported stressor exposure for men and suggested that later reports of stressor exposure are primarily accounted for by earlier reports and less so by earlier PTSD symptomatology.     

Mother–Daughter Relationship Quality and Body Image in Preadolescent Girls

Research suggests that mothers may play a role in girls’ body image development. The “interactive” hypothesis specifies that qualities of the mother–daughter relationship, as opposed to maternal modeling alone, predict daughter’s body image. We sought to understand how maternal relationship quality, from the perception of both daughters and mothers, was associated with preadolescent girls’ body image. The relationship between mother–daughter relationship quality and daughters’ body image was examined in 152 girls (ages 8–12) and their mothers. Mothers and daughters primarily identified as non-Hispanic white or Hispanic. Hierarchical linear regression analyses indicated that daughters’ perception of mother–daughter relationship quality was associated with daughters’ body esteem and body dissatisfaction, adding a small, but significant, amount of variance above the larger effect of child z-BMI and age. In contrast, maternal perception of mother–daughter relationship quality was not associated with any child body image measures. Young girls who perceived their relationships with their mothers more positively had healthier body images. Although effect sizes were relatively small and the cross-sectional design precludes conclusions regarding causality, these results support the “interactive” model of body image development whereby the characteristics of the mother–daughter relationship (as perceived by the daughter) are related to body image. Our findings support the notion that daughters’ perceptions of strong mother–daughter relationships are associated with healthy child body image, and fall in line with family-based prevention efforts that attempt to enhance parent–child relationships.     

The patenting process,innovation, and size

This paper focuses on the U.S. patenting process and how large and small entity inventors respond to it. In particular, a framework of patenting process events and activities related to success is developed and evaluated empirically, with a factor analysis revealing similarities and differences in the priorities of the two groups. The results have implications for both the conduct of the new product process under the law and for review and examination of public policy regarding patents.
