The Association of Beliefs About Heredity with Preventive and Interpersonal Behaviors in Communities Affected by Podoconiosis in Rural Ethiopia

Little is known about how beliefs about heredity as a cause of health conditions might influence preventive and interpersonal behaviors among those individuals with low genetic and health literacy. We explored causal beliefs about podoconiosis, a neglected tropical disease (NTD) endemic in Ethiopia. Podoconiosis clusters in families but can be prevented if individuals at genetically high risk wear shoes consistently. Adults (N = 242) from four rural Ethiopian communities participated in qualitative assessments of beliefs about the causes of podoconiosis. Heredity was commonly mentioned, with heredity being perceived as (1) the sole cause of podoconiosis, (2) not a causal factor, or (3) one of multiple causes. These beliefs influenced the perceived controllability of podoconiosis and in turn, whether individuals endorsed preventive and interpersonal stigmatizing behaviors. Culturally informed education programs that increase the perceived controllability of stigmatized hereditary health conditions like podoconiosis have promise for increasing preventive behaviors and reducing interpersonal stigma.     

Personality Characteristics of Patients Showing Suboptimal Cognitive Effort

This study examined the relationship between performance on the Portland Digit Recognition Test (PDRT) and the MMPI-2 in a group of veterans who were suspected of having motivation to exaggerate cognitive and/or psychiatric symptoms. Number correct on “easy” trials on the PDRT correlated inversely with MMPI-2 measures of psychopathology, whereas number correct on “hard” trials positively correlated with the same scales. Some individuals performed poorly across both types of PDRT trials and had significant MMPI-2 elevations, whereas others performed poorly only on “hard” PDRT trials and had less extreme MMPI-2 elevations. This study reinforces the need to assess the validity of both cognitive and psychiatric symptom complaints.
