Assessing Item And Scale Sensitivity To Therapeutic Change On The College Adjustment Scales: Working Toward A Counseling Center Specific Outcome Questionnaire, Christian L. Wimmer

Theses and Dissertations

Many college counseling centers use outcome measures to track therapeutic change for their clientele. These questionnaires have traditionally looked primarily at a client's symptom distress (e.g. depression, anxiety, suicidality, etc.) and are used to detect changes in the client's life that are due to therapy. Unfortunately, there is no measure that has been exclusively created and validated for use with college students. The College Adjustment Scales (CAS) form a multidimensional psychological measure designed specifically for use in college and university settings. Even though the CAS was created as a screening tool, it contains items that provide insight into changes that …

Is Talking Online To Unknown People Always Risky? Distinguishing Online Interaction Styles In A National Sample Of Youth Internet Users., Janis Wolak, David Finkelhor, Kimberly J. Mitchell

Sociology

Abstract

We examined the risk of unwanted online sexual solicitations and characteristics associated with four online interaction styles among youth Internet users. The interaction styles took into account the people with whom youth interacted online (people known in person only, unknown people met through face-to-face friends, unknown people met in chatroom, and other places online) and high- and low-risk patterns of online behavior. The aim was to provide a basis for identifying which youth may be most at risk from interacting online with unknown people.

The Effect Of Poverty On Child Development And Educational Outcomes, Patrice L. Engle, Maureen M. Black

Psychology and Child Development

Poverty affects a child’s development and educational outcomes beginning in the earliest years of life, both directly and indirectly through mediated, moderated, and transactional processes. School readiness, or the child’s ability to use and profit from school, has been recognized as playing a unique role in escape from poverty in the United States and increasingly in developing countries. It is a critical element but needs to be supported by many other components of a poverty alleviation strategy, such as improved opportunity structures and empowerment of families. The paper reviews evidence from interventions to improve school readiness of children in poverty, …

Are Maximizers Really Unhappy? The Measurement Of Maximizing Tendency, Scott Edward Highhouse, Dalia L. Diab, Michael A. Gillespie

Psychology Faculty Publications

Recent research suggesting that people who maximize are less happy than those who satisfice has received considerable fanfare. The current study investigates whether this conclusion reflects the construct itself or rather how it is measured. We developed an alternative measure of maximizing tendency that is theory-based, has good psychometric properties, and predicts behavioral outcomes. In contrast to the existing maximization measure, our new measure did not correlate with life (dis)satisfaction, nor with most maladaptive personality and decision-making traits. We conclude that the interpretation of maximizers as unhappy may be due to poor measurement of the construct. We present a more …

Effects Of Acute Ethyl Alcohol Consumption On A Psychophysical Measure Of Lateral Inhibition In Human Vision., Kevin D Johnston, Brian Timney

Brain and Mind Institute Researchers' Publications

Acute consumption of ethyl alcohol affects a variety of visual functions. However, there have been few systematic attempts to investigate the neural mechanisms underlying these effects. Here, we employed the Westheimer paradigm to investigate the hypothesis that alcohol reduces lateral inhibition within human "perceptive fields", the psychophysical analogue of physiological receptive fields. Westheimer functions obtained under alcohol and no-alcohol conditions at photopic, mesopic, and scotopic levels of adaptation showed changes consistent with an alcohol-induced decrease in lateral inhibition. We conclude that this decrease in lateral inhibition may be responsible for some of the changes in visual perception that result from …

The Contribution Of The Dorsal Root Reflex And The Sympathetic Nervous System In Formalin-Evoked Neurogenic Inflammation, Lara A. Kachlic

Psychology Theses - Archive

The present study investigated the role of dorsal root reflex (DRR), which is characterized as antidromic firing via primary afferent fibers towards the periphery, and the sympathetic nervous system in neurogenic inflammation. Neurogenic inflammation is defined as inflammation that is caused by substances released from sensory nerve terminals (Willis Jr., 1999). The first objective of the study was to determine bilateral blood perfusion, a measure of redness, one of the cardinal signs of inflammation, following a formalin injection with the use of laser Doppler imaging. The hypothesis stated that there would be a bilateral increase in blood perfusion, following formalin. …

A Short Form Of The Maximization Scale: Factor Structure, Reliability And Validity Studies, G. Y. Nenkov, M. Morrin, Andrew Ward, Barry Schwartz, J. Hulland

Psychology Faculty Works

We conducted an analysis of the 13-item Maximization Scale (Schwartz et al., 2002) with the goal of establishing its factor structure, reliability and validity. We also investigated the psychometric properties of several proposed refined versions of the scale. Four sets of analyses are reported. The first analysis confirms the 3-part factor structure of the scale and assesses its reliability. The second analysis identifies those items that do not perform well on the basis of internal, external, and judgmental criteria, and develops three shorter versions of the scale. In the third analysis, the three refined versions of the scale are cross-validated …

Stepping Up The Pressure: Arousal Can Be Associated With A Reduction In Male Aggression, Andrew Ward, T. Mann, E. H. Westling, J. D. Creswell, J. P. Ebert, Matthew Richard Wallaert , '05

Psychology Faculty Works

The attentional myopia model of behavioral control [Mann and Ward, 2007] was tested in an experiment investigating the relationship between physiological arousal and aggression. Drawing on previous work linking arousal and narrowed attentional focus, the model predicts that arousal will lead to behavior that is relatively disinhibited in situations in which promoting pressures to aggress are highly salient. In situations in which inhibitory pressures are more salient, the model predicts behavior that is relatively restrained. In the experiment, 81 male undergraduates delivered noise-blasts against a provoking confederate while experiencing either high or low levels of physiological arousal and, at the …

Disruptive Effects Of Aβ Oligomers To The Radial-Arm Maze Performance Of Rats, Kineta Lynn Morgan-Paisley

Dissertations

Converging lines of research have implicated a causal relationship between oligomers of amyloid-β and the cognitive impairments associated with Alzheimer's disease (AD); however, very few studies have provided direct experimental evidence of this relationship and none of those studies have used an established model of working memory. The present study used an established model of working memory, the radial-arm maze, to examine the effects of amyloid-β oligomers on the memory of two groups of rats. The experimental group received ICV injections of the culture media (CM) of Chinese Hamster Ovary (CHO) cells transfected with a human mutation of APP containing …

A Comparison Of Three Training Methods On The Acquisition And Retention Of Automotive Product Knowledge, Rhiannon M. Fante

Dissertations

The purpose of this study was to compare the effects of a traditional (non-fluency) web-based training program with and without study objectives with a web-based fluency-building training program on the acquisition and retention of automotive product knowledge. The effects of the training conditions were assessed by how accurately and quickly participants responded on a product knowledge test immediately after training, four weeks after training, and eight weeks after training. A three-group between subjects design was used with 20 college students in each group. Results indicated that participants in the fluency training group were more accurate and fluent immediately after training, …

A Qualitative Study Of Buddhist Informed Psychotherapists, Michael Sean Harris

Dissertations

The field of psychology has a history of distancing itself, if not outright dismissing, both religion and spirituality. In recent years, however, psychology has come to move more toward an embrace of religious and spiritual experience. Buddhism, often expressed as a philosophical system without regard to theistic or nontheistic underpinnings, has been integrated with psychological theory in recent scholarly literature. This dissertation is an exploratory study regarding howBuddhist psychological perspectives are applied in actual psychotherapeutic practice. A participant pool of ten psychotherapists who self-identified as utilizing Buddhism in their work was studied along a variety of dimensions. Demographic questionnaires, audiotaped …

The Development Of Day-Night Differences In Sleep And Wakefulness In Norway Rats And The Effect Of Bilateral Enucleation, Andrew J. Gall, William D. Todd, Baisali Ray, Cassandra M. Coleman, Mark S. Blumberg

Faculty Publications

The suprachiasmatic nucleus (SCN) exhibits circadian rhythmicity in fetal and infant rats, but little is known about the consequences of this rhythmicity for infant behavior. Here, in Experiment 1, we measured sleep and wakefulness in rats during the day and night in postnatal day (P)2, P8, P15 and P21 subjects. As early as P2, day-night differences in sleep-wake activity were detected. Nocturnal wakefulness began to emerge around P15 and was reliably expressed by P21. We hypothesized that the process of photic entrainment over the first postnatal week, which depends upon the development of connectivity between the retinohypothalamic tract (RHT) and …

Ptsd Symptoms And Self-Rated Recovery Among Adult Sexual Assault Survivors: The Effects Of Traumatic Life Events And Psychosocial Variables, Cynthia J. Najdowski, Sarah E. Ullman

Psychology Faculty Scholarship

Prior research has demonstrated that self-blame is predictive of more PTSD symptoms and poorer recovery (Frazier, 2003; Koss, Figueredo, & Prince, 2002), and perceived control over recovery is associated with less distress (Frazier, 2003) in adult sexual assault (ASA) survivors. A structural equation model was tested to examine the role of traumatic events, self-blame, perceived control over recovery, and coping strategies on PTSD symptoms and self-rated recovery in women ASA survivors. Adaptive coping partially mediated the effects of other traumas, self-blame, and perceived control over recovery on PTSD symptoms, and showed a small positive association with increased PTSD symptoms. As …

Day Length And Estradiol Affect Same-Sex Affiliative Behavior In The Female Meadow Vole, Annaliese K. Beery, Theresa J. Loo, Irving Zucker

Neuroscience: Faculty Publications

Non-sexual social bonding between adult mammals remains poorly understood, despite its importance in many species. Female meadow voles are territorial and nest alone in long summer day lengths when circulating estradiol concentrations are high, but cohabit in groups in short winter photoperiods when estradiol secretion is low. The influence of day length and estradiol on same-sex huddling behavior was assessed in adult female pairs housed together in long day lengths (LDs) or short day lengths (SDs) from weaning. The behavior of intact, ovariectomized, and estradiol-treated ovariectomized females from each photoperiod was assessed during 3 hour partner preference tests. Intact SD …

Child Sexual Trauma: Testing The Robustness Of Browne & Finkelhor's Theory, Jose Mauricio Ramirez

Loma Linda University Electronic Theses, Dissertations & Projects

Trauma has received great attention in the last three decades and a major societal issue today is child sexual abuse. Twelve percent of victims of maltreatment every year are victims of child sexual abuse (CSA). Several studies have suggested that the prevalence of CSA in women is in the range of 6% to 62% depending on how the data was collected (e.g., interviews, surveys) and the nature of the population sampled (e.g., general population, clinical population). Because of CSA, victims are impacted by the experience and encounter a change in the way they perceive the world on both the way …

Predicting Long-Term Memory In Adult Brain Injury Patients Using Mr Spectroscopy, Herminia De La Rosa-Trujillo

Loma Linda University Electronic Theses, Dissertations & Projects

Accurate outcome prediction has proven to be somewhat elusive for patients with traumatic brain injury (TBI). The difficulty is due to the sometimes inaccurate methods of prediction currently available. Despite the advances seen in radiological technology, the traditional methods of x-rays, CT scans and MRIs are not always accurately able to predict patient functional outcome. These radiological methods are adequate in determining gross structural anatomical disturbances, however, they unable to detect more diffuse cellular damage believed to be responsible for the functional impairments evidenced in patients sustaining TBI. Magnetic Resonance Spectroscopy (MRS) is an imaging technique which measures brain metabolites …

Factors That Affect Performance On Executive Functioning After Coronary Artery Bypass Grafting, Sapna Mahesh Patel

Loma Linda University Electronic Theses, Dissertations & Projects

Research suggests that individuals who undergo coronary artery bypass grafting (CABG) experience declines in neuropsychological functioning post-operatively. This decline has been observed in up to 80% of patients early after surgery, and in up to 30% of patients after six months. Many studies have examined the potential effects of CABG on neuropsychological functioning in general, and numerous studies have found that executive functions are impaired in particular. However, none have examined what factors contribute to observed executive dysfunction after CABG. This study investigated the role of memory functions on executive functions in a selected sample of patients undergoing CABG. This …

Parental Readiness For Change And Involvement In Treating Children With Obesity, Aileen Arratoonian Vedda

Loma Linda University Electronic Theses, Dissertations & Projects

Several studies have demonstrated benefits of parental involvement in intervention programs for Childhood Obesity. However, limited research is available on Parent Readiness for Change. This study utilized archival data from the LLU Growing Fit Obesity Clinic to assess Parent Readiness for Change (PRC) and involvement in a 12- week multidisciplinary program for obese children, as a predictor of medical and psychological outcomes. Data from forty-nine children aged 6-16 (M= 10.47) were eligible and included. Their caregivers who participated in the program included; 86% mothers, 7 % fathers, and 7 % relatives. The caregiver mean age was M=39.6. PRC was assessed …

Cultural Beliefs About Health Professionals, Attributions For Mistreatment, And Continuity Of Cancer-Related Care, Jennifer Anne Tucker

Loma Linda University Electronic Theses, Dissertations & Projects

This research examined attributions for health care mistreatment, related emotions, and the role of cultural beliefs about health care professionals as determinants of cancer-related continuity of care among Anglo and Latino women in Southern California. This research was guided by Betancourt’s model of culture adapted for the study of health behavior (Betancourt & Flynn, 2008) and Weiner’s (1996) attribution theory of motivation and emotion. As predicted, higher levels of negative cultural beliefs about health professionals resulted in lower intentions for continuity of care indirectly through mediating psychological perceptions of intentionality for mistreatment, controllability of its causes, and anger toward the …

Identifying The Most Effective Stimulus To Promote Wayfinding In Elders With Dementia, Allison A. Jay

Masters Theses

When nursing home residents with dementia experience difficulty locating their bedroom, it can create problems for other residents and staff. This study investigated the ability of four elders with severe dementia to recognize various self-referent stimuli (i.e., young adulthood photograph, middle adulthood photograph, current photograph, and printed name). Two of the three participants who were able to complete the assessment recognized their photographs from earlier in life and their printed names but were not able to recognize their current photograph. These two residents then participated in an intervention in which the recognized stimuli were posted outside their bedroom doorway during …

The Role Of Self-Consciousness In The Experience Of Alcohol-Related Consequences Among College Students, Joseph W. Labrie, Eric R. Pedersen, Clayton Neighbors, Justin F. Hummer

Heads Up!

Heavy drinking among college students is a well-established national concern. An in-depth look at the characteristics and traits of heavy drinking students is an essential precursor to the development of successful targeted interventions with at-risk students. The current study examines the role self-consciousness (private, public, social anxiety) plays in the experience of alcohol-related consequences among a sample of 1,168 student members of campus organizations. Male gender predicted drinking in the sample, while both private self-consciousness and social anxiety predicted less drinking. Public self-consciousness predicted alcohol-related consequences over and above the variance explained by drinking for both males and females. Additionally, …

Self-Solicited Feedback: Effects Of Hourly Pay And Individual Monetary Incentive Pay, Julie M. Slowiak

Dissertations

The frequency of feedback solicitation under hourly pay and individual monetary incentive pay conditions was examined. A two-group between-subjects design was used with 30 college students in each group. Participants attended three experimental sessions and entered the cash value of simulated bank checks presented on a computer screen. Results indicated that (a) participants who were paid individual monetary incentives did not self-solicit feedback more often than those who were paid an hourly wage, (b) feedback solicitation was not related to individual differences in levels of competition with one's self or competition with others, (c) task performance was higher for individuals …

Sustainability From The Perspectives Of Indigenous Leaders In The Bioregion Defined By The Pacific Salmon Runs Of North America, David Edward Hall

As the evidence mounts and more people awaken to this reality, increased attention is being dedicated to the pursuit of answers for a just and sustainable future. This dissertation grew from the premise that effectively moving towards sustainability requires change at all levels of the dominant Western culture, including deeply held worldviews. The worldviews of many indigenous cultures offer alternative values and beliefs that can contribute to addressing the root causes of problems related to sustainability. In the bioregion defined by the Pacific Salmon runs of …

Fire/Emergency Medical Services And Coping Methods: Mitigating Traumatic Stress Symptomatology, William Mark Holland

Doctoral Dissertations and Projects

Firefighters and Emergency Medical Services (EMS) professionals must cope with a variety of job-related stressors. One significant stressor for fire/EMS providers involves exposure to personally disturbing incidents (PDIs). To manage the untoward effects of exposure to PDIs, fire/EMS professionals use a variety of coping methods. In this study, the effectiveness of various coping methods utilized by fire/EMS professionals for mitigating the negative effects of exposure to PDIs was examined. This study provides some clarity by identifying the subjective distress associated with certain PDIs and pinpointing detrimental coping methods of fire/EMS personnel through scores on the 28-item General Health Questionnaire and …

Mindfulness In Childbirth: An Investigation Of The Effects Of Mindfulness Training On Maternal Satisfaction With Childbirth And Obstetric Outcomes, Brenda L. Bratton

Dissertations

This study investigated the effects of mindfulness training on obstetric outcomes and maternal satisfaction with childbirth. We were interested in whether mindfulness training was more effective than a control group receiving psychoeducation on stress reduction. The goal of the intervention group was to increase participants' moment-to-moment awareness of thoughts, feelings, and body sensations during childbirth so that they would respond to these experiences rather than react to them in an automatic manner. These strategies were hypothesized to help a laboring woman minimize fear or anxiety associated with pain and complications and be more adaptive to whatever circumstances arose. Repeated measures …
