Item Is disgust proneness prospectively associated with influenza vaccine hesitancy and uptake?(Springer Science and Business Media LLC, 2022-05) Shook, Natalie J.; Fitzgerald, Holly N.; Oosterhoff, Benjamin; MacFarland, Eva; Sevi, BarışAlthough various demographic and psychosocial factors have been identified as correlates of influenza vaccine hesitancy, factors that promote infectious disease avoidance, such as disgust proneness, have been rarely examined. In two large national U.S. samples (Ns = 475 and 1007), we investigated whether disgust proneness was associated with retrospective accounts of influenza vaccine uptake, influenza vaccine hesitancy, and eventual influenza vaccine uptake, while accounting for demographics and personality. Across both studies, greater age, higher education, working in healthcare, and greater disgust proneness were significantly related to greater likelihood of previously receiving an influenza vaccine. In Study 2, which was a year-long longitudinal project, disgust proneness prospectively predicted influenza vaccine hesitancy and eventual vaccine uptake during the 2020–2021 influenza season. Findings from this project expand our understanding of individual-level factors associated with influenza vaccine hesitancy and uptake, highlighting a psychological factor to be targeted in vaccine hesitancy interventions.Item Surgency: a holistic model(Montana State University - Bozeman, College of Letters & Science, 2017) Canen, Mara June; Chairperson, Graduate Committee: Rebecca BrookerPrevious examinations of the temperamental trait surgency have largely focused on single facets of the global construct rather than attempting to identify how- or if- individual facets truly converge to comprise a global trait. The current project tested a holistic model of surgency based on temperament theory (Rothbart & Derryberry, 1981) that used a multi-trait multimethod approach to integrate multiple domains of regulation and reacitivity. Four models were tested that included measures of physiological regulation, behavioral regulation, emotion regulation, and parent-reported temperament. A single model emerged that accounted for biological, behavioral, affective, and parent-reported, domains of surgency in 3.5 year old children. This model comprised high levels of positive affect, fidgeting, impulsivity, and RSA suppression loading onto a single latent factor of high surgency. This work contributes to the temperament literature by providing initial evidence for a holistic composite of surgency during early childhood that is consistent with classic temperament definitions of surgency.Item Cult experience : abuse, psychological distress, close relationships, and personality characteristics(Montana State University - Bozeman, College of Letters & Science, 1997) Gasde, IreneCultic groups distinguish themselves from benign groups through their use of unethical means of persuasion, control, and exploitation. Most people view those who join cults as different from the norm and attribute their psychological problems after leaving cults to personal deficiencies. This study investigated 61 former members of the controversial Church Universal and Triumphant (CUT), evaluating their perceptions of the group’s abusiveness, their level of psychological distress and personality characteristics, as well as changes in the quality of their close personal relationships. Although responses to the Group Psychological Abuse Scale revealed non-abusive pre-involvement perceptions of CUT, current perceptions reflected higher abusiveness, suggesting changes in the interpretations of events for these two time frames, possible misrepresentation on the part of the group, or both. On the revised Symptom Check List-90, many respondents reported high levels of psychological distress, which were influenced by spousal relationships during and after CUT involvement and which decreased since leaving CUT. Respondents’ scores on the Eysenck Personality Questionnaire fell mostly within the normal range, except for extroversion, which fell below the norm. Respondents reported that personal relationships deteriorated during CUT involvement. Similar studies investigating other controversial groups are needed. Research focused on the development of instruments and methodologies permitting the study of children with cult histories would contribute to expanding current understanding of the impact of cults.Item Duration estimates and behavioral measures as a function of sex and personality(Montana State University - Bozeman, College of Letters & Science, 1985) Warner, Donald James
