The construction and validation of the fullerton ontological confusion scale

Pasquarella, Fred Joseph 04 December 2015 (has links)
<p> The Fullerton Ontological Confusion (FOC) scale was constructed to address the issues of inconsistent theory and inadequate measurement regarding paranormal, superstitious, magical, and supernatural (PSMS) beliefs. For the FOC scale, PSMS beliefs were defined as confusions of ontology, or the misattribution of core knowledge belief categories. The FOC was empirically evaluated under an Item Response Theory framework using the nominal response model (NRM) to estimate item parameters and the Wald test to evaluate within-item category variation. Using the NRM and the Wald test, the FOC scale items were revised to yield a measure that was optimally formatted and informative. Correlational analysis was used to validate the FOC scale by testing the hypothesized relationships to theoretically related and unrelated constructs. The FOC scale was found to have a good degree of validity with most of the testable validation hypotheses being supported. Compared to the available existing measures, the FOC scale could be used as a more pure and informative measure for PSMS beliefs. </p>

Impact of gender, perception of being overweight and fat acceptance on personal agency| Establishing additional validity and reliability for the personal agency questionnaire

Lundquist, Simone 16 October 2015 (has links)
<p> The overarching goal of psychoanalytic and narrative therapies is to increase agency; however, few tools assess for agency. The Personal Agency Questionnaire (PAQ) was developed for this purpose and was found to be a valid and reliable instrument (Lundquist, 2012). The primary aims of this study were to (a) replicate past findings by performing correlations between the PAQ and scales measuring constructs thought to be part of agency (RSES for self-esteem; GSE for self-efficacy, and IPC for internal locus of control), (b) increase internal consistency and reliability of the PAQ through performing a factor analysis, and (c) establish additional validity by performing regressions to determine how three additional variables were related to agency: gender, perception of being overweight, and antifat attitudes. Females were expected to score lower than males on the PAQ because of the influence of gender norms on agency. Overweight status has shown a negative relation to agency, self-efficacy, and self-esteem; however, the fat- accepting individuals were expected to have greater agency compared to those who have internalized the culture&rsquo;s antifat messages. Participants accessed the online survey through postings on Craig&rsquo;s List and Yahoo discussion groups. Analyses were conducted with 280 participants, a majority of whom were White (65%), female (74%), employed (59%), highly educated (64% had college degree or greater, 33.20% attended some college), and had attended therapy (68%). Factor analysis revealed 4 factors underlying the PAQ (which replaced the previously hypothesized 6 subscales); items of the PAQ were reduced from 42 to 24, increasing reliability among the factors, with &alpha; = .78, &alpha; = .78, &alpha; = .72, &alpha; = .73, and the total reliability from &alpha; = .62 to &alpha; = .90. The new PAQ had stronger correlations than previously with the three scales that established its construct validity. Fat acceptance, age, education and therapy were significantly, positively correlated with agency. When looking at gender alone, or perceptions of being fat alone or in combination with gender, no differences in agency were evident. However when adding the antifat variable to gender and perceptions of being overweight, being female, significantly overweight, with antifat attitudes predicted reduced agency.</p>

Cognitive Deficits and Changes in Ethanol Intake in Offspring of Male Alcoholics

Pappas, Jessica 14 March 2018 (has links)
<p> Alcoholism and alcohol use disorders are a major problem worldwide. Excessive alcohol consumption has been associated with cognitive impairment not only in drinkers but also in their offspring. Previous clinical reports have suggested that inherited drug use behavior in individuals, including the overall amount of alcohol consumed, originates from parents who engage in the consumption of alcohol both during and prior to conception. For example, mothers exposed to alcohol during pregnancy have been shown to produce offspring with neurodevelopmental, physiological, and behavioral deficits, in rodents. Additionally, several studies now support the idea that fathers exposed to alcohol prior to mating produce male offspring with developmental, physiological, and cognitive deficits as well. With this said, alcohol exposed fathers appear to pass different phenotypes to their sons than they do their daughters. To date, little research has been dedicated to examining cognitive deficits associated with paternal alcohol exposure or the volume of alcohol intake in daughters of male alcoholics. The purpose of this set of experiments is to explore possible changes in cognitive function and alcohol acceptance in both male and female offspring of alcohol-exposed fathers. Adult male rats were exposed to a repeated binge dose of alcohol and later mated with non-manipulated females. Offspring of exposed fathers were assessed for levels of alcohol consumption via Intraoral Cannulation, followed by a series of cognitive function tests via T-maze task performance. Accuracy percentage within the T- maze and volume of alcohol accepted were compared and analyzed using an ANOVA. Our findings suggest that paternal binge doses of ethanol exposure prior to breeding results in offspring that consume significantly more ethanol than controls, exhibit greater latency time to reach criterion in a T-maze, and having significantly fewer percent correct responses in T-maze task performance when including all trials. The results presented here add to the growing body of literature aimed at understanding the consequences of paternal pre-conception ethanol exposure and the effects on subsequent generations.</p><p>

A Quantitative Descriptive Study Using the Theoretical Domains Framework to Investigate and Compare the Psychotropic Medication Prescribing Behavior of Primary Care Prescribers

Sever, Renae Sandin 13 April 2018 (has links)
<p> Psychotropic medications rank among the most widely prescribed, largest-selling, and fastest-growing classes of drugs in the U.S. today. Largely attributed to the role of primary care providers in mental health care and the use of psychotropic medications for non-psychiatric conditions, the prevalence of psychotropic medication prescribing is a problem due to side effects, drug-to-drug interactions, and withdrawal effects. Previous research has not reliably explained why practitioners vary in prescribing behavior. This non-experimental cross-sectional quantitative research investigation compared the psychotropic medication prescribing behavior of primary care prescribers from the perspective of the theoretical domains framework (TDF), a validated theoretical framework for identifying factors influencing clinical behavior. The inquiry was guided by four research questions that explored prescribing behavior between primary care physicians (MDs, DOs), physician assistants (PAs), and nurse practitioners (NPs), between high and low prescribers, among high prescribers, and among low prescribers. The Determinants of Implementation Behavior Questionnaire: Psychotropic Medication Prescribing Behavior (DIBQ: PMPB), a unique psychotropic medication prescribing behavior version of the TDF-based Determinants of Implementation Behavior Questionnaire (DIBQ) template was administered to 49 Pennsylvania primary care MDs, DOs, PAs, and NPs. Due to low sample size, the groups were aggregated and compared between MDs/DOs and PAs/NPs. Data were analyzed with the non-parametric Kruskal-Wallis H test. Results revealed that mean ranks were significantly different only among low prescribers in which MDs/DOs were significantly higher than PAs/NPs in Socio-political context and Innovation strategy. However, PAs/NPs were higher than MDs/DOs in Social/professional role and identity and Intentions. Findings suggest that differences may be related to division of labor, primary care setting, and age and gender of provider. MDs/DOs may focus more on protocol, organization, and practice-based aspects of running a business, whereas PAs/NPs may have a holistic mindset that is more flexible, accommodating, and sensitive to the patient. These factors should be thoroughly investigated in randomized controlled trials to more fully understand a provider&rsquo;s motivation and pattern for prescribing psychotropic medications, particularly in situations where safer evidence-based treatments exist.</p><p>

Modeling Dyadic Attunement: Physiological Concordance in Newly Married Couples and Alliance Similarity in Patient-Therapist Dyads

Laws, Holly 01 January 2014 (has links)
Mutual influence within relationships is theorized as central to human development and functioning across the lifespan. Multiple theories posit a process of progressive bidirectional influence that results in greater similarity between dyad members over time, termed attunement. Yet attunement processes, from dyadic synchrony in healthy child development to partner influence within romantic relationships, are difficult to measure and model. One difficulty is that capturing information from both members of a relationship pair, or dyad, requires statistical modeling that appropriately accounts for the interdependence between them. The present study addressed this issue by putting forward a framework for modeling attunement processes between relationship members over time, and applied this framework to two distinct studies. The studies both tested whether attunement occurred in two large-scale dyadic samples, the first in a sample of newly-married couples, the second in a sample of psychotherapy dyads. Attunement was modeled both as an outcome (in Study 1) and a predictor (in Study 2), providing interested researchers with an analytic framework for using measures of dyadic attunement as either an independent or a dependent variable. Findings from Study 1 showed significant attunement in the stress hormone cortisol over the early years of marriage in newlywed couples. This finding is suggestive of bidirectional spousal influence over a longer term than previously tested, as other studies have only inferred attunement processes by finding covariation in spousal cortisol over a matter of days. This study also disaggregated cortisol fluctuations into discrete parts, allowing for tests of spousal attunement not only in cortisol level, but also in physiological response to a stressor. Findings from Study 2 also found significant attunement processes within patient-therapist dyads. Specifically, patient-therapist alliance attunement over time was predictive of better outcome for patients receiving psychotherapy for chronic depression. A major contribution of these studies was that they modeled theorized relationship processes at the level of the dyad, rather than emphasizing individual outcomes. This dyadic-level modeling of bidirectional influence in turn related to outcomes relevant to psychological health, which may have been obscured or undetectable with other modeling techniques.

Assessing situations on social media| Temporal, demographic, and personality influences on situation experience

Serfass, David G. 14 October 2016 (has links)
<p> Social media posts are used to examine what people experience in their everyday lives. A new method is developed for assessing the situational characteristics of social media posts based on the words used in these posts. To accomplish this, machine learning models are built that accurately approximate the judgments of human raters. This new method of situational assessment is applied on two of the most popular social media sites: Twitter and Facebook. Millions of Tweets and Facebook statuses are analyzed. Temporal patterns of situational experiences are found. Geographic and gender differences in experience are examined. Relationships between personality and situation experience were also assessed. Implications of these finding and future applications of this new method of situational assessment are discussed.</p>

Reliability and validity of a sociometric picture rating scale for preschoolers

Kalesnik, Joanne Frances 01 January 1990 (has links)
The purpose of this study was to investigate the degree to which preschool children are able to provide reliable and valid sociometric data pertaining to their classroom peers. The applicability of a sociometric picture rating scale was assessed by examining its concurrent validity using the Kohn Social Competence Scale, a teacher rating instrument designed to provide an indication of the classroom social behavior of preschool children based on teacher observation. Reliability of the sociometric rating scale was investigated through a test-retest procedure over a six-week interval. Subject were thirty-two 3 and 4 year olds (16 male; 16 female) attending public school preschool programs in a rural community in Western Massachusetts. The data obtained included two sets of sociometric scores for each subject (test, retest) as well as scores from the rating scales teachers completed for each subject. Analysis of the data involved investigation of the strength of association between teacher rating scale scores and sociometric scores, as well as stability of the sociometric scores over the six-week test-retest interval. Additionally, analyses were undertaken to determine if there were statistically significant differences in the sociometric scores due to a subject's age, gender, prior socialization experiences, or Special Education status. Results indicated fairly good reliability of the sociometric picture rating scale (correlation between the test and retest sets of scores =.71, p $<$.01). Significant relationships were also found between the sociometric scores and those obtained from the teacher rating scale. Therefore, concurrent validity of the sociometric measure was demonstrated. The only differences of statistical significance found in the sociometric scores were those related to a subject's gender. In this study, females were more likely to receive high sociometric ratings from peers and males were more likely to receive low ratings. Based on the findings, it was concluded that the picture rating scale technique represents a valid and reliable sociometric measure for preschoolers. It was suggested that sociometrics always be used in conjunction with other measures of social functioning, namely direct observations of behavior or teacher rating scales.
