Negative Affectivity And Its Impact On Role Conflict, Role Ambiguity, And Job Satisfaction, Amy Rachelle Cooper

FIU Electronic Theses and Dissertations

Of the nine meta-analyses conducted, correlational data were found in support of all hypothesized direct effects models, most mediational models, but no moderator or suppressor models.

The Genetic And Environmental Effects Of Parental Age On The Expression Of Psychopathology In Adoptees, Lyndon Joseph Aguiar

FIU Electronic Theses and Dissertations

Secondary analysis of 581 adoptees was utilized to determine if parental age is related, either genetically or environmentally, to the development of psychopathology.

The significant results showed that proband adoptees (with psychopathology in biologic relatives) with younger birthparents had increased alcohol abuse and those with younger birthfathers had increased antisocial personality while adoptees with older birthparents had increased depression. Analyses on control adoptees (with background free of known genetic disturbances) showed that those with younger adoptive mothers had increased antisocial personality and drug abuse and those with younger adoptive fathers had increased antisocial personality while adoptees with older adoptive fathers …
