Assessing Heterogeneity In Meta-Analysis: Q Statistic Or I2 Index?, Tania Huedo-Medina, Julio Sanchez-Meca, Fulgencio Marin-Martinez, Juan Botella

CHIP Documents

In meta-analysis, the usual way of assessing whether a set of single studies is homogeneous is by means of the Q test. However, the Q test only informs meta-analysts about the presence versus the absence of heterogeneity, but it does not report on the extent of such heterogeneity. Recently, the I² index has been proposed to quantify the degree of heterogeneity in a meta-analysis. In this article, the performances of the Q test and the confidence interval around the I² index are compared by means of a Monte Carlo simulation. The results show the utility of the I² index as …

What Do Children Want To Know About Animals And Artifacts? Domain-Specific Requests For Information, M. L. Greif, Deborah G. Kemler Nelson, F. C. Keil, F. Gutierrez

Psychology Faculty Works

Children's questions may reveal a great deal about the characteristics of objects they consider to be conceptually important. Thirty-two preschool children were given opportunities to ask questions about unfamiliar artifacts and animals. The children asked ambiguous questions such as “What is it?” about artifacts and animals alike. However, they were more likely to ask about the functions of artifacts, but about category membership, food choices, and typical locations of animals. They never asked questions about either artifacts or animals that would be considered inappropriate by adults. The results indicate that children hold different expectations about the types of information important …

Adverse Impact Of A History Of Violence For Women With Breast, Cervical, Endometrial, Or Overian Cancer, Susan C. Modesitt, Alisa C. Gambrell, Hope M. Cottrill, Lon R. Hays, Robert J. Walker, Brent J. Shelton, Carol E. Jordan, James E. Ferguson

Office for Policy Studies on Violence Against Women Publications

The experience of physical and sexual violence (victimization) is common among U.S. women and is associated with adverse health consequences. The study objectives were to estimate the prevalence of victimization in women with cancer and to examine associations with demographics, cancer screening, and cancer stage.

METHODS:

From 2004 to 2005, 101 women with breast, cervical, endometrial, or ovarian cancer were interviewed to collect demographics, cancer screening history, health care access/use, and violence history. Chisquare and Fisher exact tests were used test risk-factor associations. A multinomial logistic regression model was used for multivariable analysis.

The prevalence of a history of …

Chronic Pain In A Couples Context: A Review And Integration Of Theoretical Models And Empirical Evidence, Michelle T. Leonard, Annmarie Cano, Ayna B. Johansen

Psychology Faculty Research Publications

Researchers have become increasingly interested in the social context of chronic pain conditions. The purpose of this article is to provide an integrated review of the evidence linking marital functioning with chronic pain outcomes including pain severity, physical disability, pain behaviors, and psychological distress. We first present an overview of existing models that identify an association between marital functioning and pain variables. We then review the empirical evidence for a relationship between pain variables and several marital functioning variables including marital satisfaction, spousal support, spouse responses to pain, and marital interaction. On the basis of the evidence, we present a …

The Attribution Of Intentionality In Relation To Culture And Self, Gangaw Zaw

Loma Linda University Electronic Theses, Dissertations & Projects

The attribution of intentionality has received significant attention in the social cognition literature (Malle, 1999). Perceiving the intentions of others has several implications for how individuals judge and respond to others' behaviors in various social situations. The current study examined factors that predict attributions of intentionality. Studies by Jones and Davis (1965) have indicated the role of culture is involved in perceptions of intentionality. In addition, studies in philosophy have implicated the self as influential in the perception of intentionality. The self is also a product of culture and cultural value orientations (e.g. individualism and collectivism). Markus and Kitayama (1991) …

Using The Outcome Questionnaire 45.2 In Obesity Treatment, Adam L. Arechiga

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: The purpose of this study was to determine if the Outcome Questionnaire 45.2 (OQ-45) can be used in the treatment of obesity to predict participant dropout and initial treatment success, in terms of weight loss (Lambert et. al, 2002a). The OQ-45 has been used with success to predict dropout from psychotherapy in clinical populations. It was hypothesized that higher pretreatment OQ-45 scores would be associated with less program completion and less weight loss by the end of treatment.

Method: The study employed a non-experimental time series design. Seventy-eight participants were recruited from the three local obesity treatment programs, which …

Empirically And Clinically Useful Decision Making In Psychotherapy: Differential Predictions With Treatment Response Models, Wolfgang Lutz, Stephen M. Saunders, Scott C. Leon, Zoran Martinovich, Joachim Kosfelder, Dietmar Schulte, Klaus Grawe, Sven Tholen

Psychology Faculty Research and Publications

In the delivery of clinical services, outcomes monitoring (i.e., repeated assessments of a patient's response to treatment) can be used to support clinical decision making (i.e., recurrent revisions of outcome expectations on the basis of that response). Outcomes monitoring can be particularly useful in the context of established practice research networks. This article presents a strategy to disaggregate patients into homogeneous subgroups to generate optimal expected treatment response profiles, which can be used to predict and track the progress of patients in different treatment modalities. The study was based on data from 618 diagnostically diverse patients treated with either a …

Comparing Chemical Dependency And Mental Health Programs For The Dually Diagnosed, Kelly L. Hacker

Loma Linda University Electronic Theses, Dissertations & Projects

In order to better understand the needs of an increasing dually diagnosed population, this study compares the efficacy of integrated vs. nonintegrated treatment programs for a dually diagnosed population, residing at a Long Term Care facility in San Bernardino, California. Patients in this setting are diagnosed with chronic and acute mental illness and chemical dependency. This study tested the hypotheses that the nonintegrated treatment program would result in a higher frequency of assaults, PRNs, Q15s, and Code Reds; increase the duration of Q15s; and, increase the Addiction Severity Index’s (ASI) Family/Social and Psychiatric subscales’ scores, which would indicate lower levels …

Early Parenting And Children's Relational And Physical Aggression In The Preschool And Home Contexts, Juan F. Casas, Stephanie M. Weigel, Nikki R. Crick, Jamie M. Ostrov, Kathleen E. Woods, Elizabeth A. Jansen Yeh, Catherine A. Huddleston-Casas

Psychology Faculty Publications

This study investigated early parent- child relationships and how children's use of relational and physical aggression varies with aspects of those relationships during the preschool years. Specifically, parenting styles, parents' use of psychological control, and parents' report of their children's reunion behaviors were assessed. Analyses revealed significant associations between children's use of both relational and physical aggression and parents' reports of their own and their partner's parenting style, psychological control behaviors, and indicators of the attachment relationship. The results highlight the importance of investigating both mothers' and fathers' parenting and the sex of the child in studies of potential links …

Workplace, Household, And Personal Predictors Of Pesticide Exposure For Farmworkers, Sara A. Quandt, María A. Hernández-Valero, Joseph G. Grzywacz, Joseph D. Hovey, Melissa Gonzales, Thomas A. Arcury

Psychological Science Faculty Publications

In this article we identify factors potentially associated with pesticide exposure among farmworkers, grade the evidence in the peer-reviewed literature for such associations, and propose a minimum set of measures necessary to understand farmworker risk for pesticide exposure. Data sources we reviewed included Medline, Science Citation Index, Social Science Citation Index, PsycINFO, and AGRICOLA databases. Data extraction was restricted to those articles that reported primary data collection and analysis published in 1990 or later. We read and summarized evidence for pesticide exposure associations. For data synthesis, articles were graded by type of evidence for association of risk factor with pesticide …

Sex Differences In Regret: All For Love Or Some For Lust?, Neal J. Roese, Ginger L. Pennington, Jill Coleman, Maria Janicki, Norman P. Li, Douglas T. Kenrick

Research Collection School of Social Sciences

Few sex differences in regret or counterfactual thinking are evident in past research. The authors discovered a sex difference in regret that is both domain-specific (i.e., unique to romantic relationships) and interpretable within a convergence of theories of evolution and regulatory focus. Three studies showed that within romantic relationships, men emphasize regrets of inaction over action (which correspond to promotion vs. prevention goals, respectively), whereas women report regrets of inaction and action with equivalent frequency. Sex differences were not evident in other interpersonal regrets (friendship, parental, sibling interactions) and were not moderated by relationship status. Although the sex difference was …

A Biopsychosocial Perspective Of Gulf War Illness: A Structural Model, Katherine N. Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

Veterans deployed during the Persian Gulf War in 1990-1991 report significantly more nonspecific symptoms and poorer health than their nondeployed peers. This amalgamation of chronic, multisymptom health complaints is commonly referred to as Gulf War Illness. There are two major theoretical models within the medical/health field that may help explain these symptoms: 1) the traditional biomedical model, and 2) the more recently evolved (late 1970’s) biopsychosocial model. Theorists have proposed two major causal pathways in studying the etiology of health complaints of Gulf War veterans, the physical pathway and the psychosocial pathway. In the present study, the biopsychosocial model was …

An Ecological Momentary Assessment Of Retrospective Memory Accuracy In Patients With Obsessive-Compulsive Disorder, Andrew T. Gloster

Master's Theses and Doctoral Dissertations

Numerous studies have demonstrated the pervasiveness of inaccuracies in patients’ retrospective recall of their symptoms (e.g., Stone, Broderick, Shiffman, & Schwartz, 2004). Assessment methods that rely heavily on retrospective recall may lead to faulty clinical inferences should a patient’s recall be biased or inaccurate. Despite lingering concerns about the accuracy of retrospective recall in a variety of clinical and nonclinical populations, investigators have not studied individuals diagnosed with obsessive-compulsive disorder (OCD). This is troubling given findings from laboratory studies that OCD patients may have deficits in episodic memory (Muller & Roberts, 2005). This study investigated memory accuracy in OCD patients …

Conceptualizing And Measuring The Self In Chronic Illness And Its Relationship To Adjustment, Jessica Marie Morea

Dissertations and Theses

This research sought to clarify the role of the self in chronic illness by developing and evaluating several new constructs, which intend to describe the extent to which illness permeates the self-concept. Following the works of Lewin and Asch, the concepts of central and peripheral regions of the self were elaborated to describe the state of illness within the self, termed "illness self-concept".

Three subsidiary constructs were introduced to further depict illness self-concept: directionality, pervasiveness, and illness self-consciousness. Directionality refers to whether illness drives the self or self drives illness. Pervasiveness refers to whether illness affects many or few regions …

Representation Of Head-Centric Flow In The Human Motion Complex., Jeroen Goossens, Sean P Dukelow, Ravi S Menon, Tutis Vilis, Albert V Van Den Berg

Brain and Mind Institute Researchers' Publications

Recent neuroimaging studies have identified putative homologs of macaque middle temporal area (area MT) and medial superior temporal area (area MST) in humans. Little is known about the integration of visual and nonvisual signals in human motion areas compared with monkeys. Through extra-retinal signals, the brain can factor out the components of visual flow on the retina that are induced by eye-in-head and head-in-space rotations and achieve a representation of flow relative to the head (head-centric flow) or body (body-centric flow). Here, we used functional magnetic resonance imaging to test whether extra-retinal eye-movement signals modulate responses to visual flow in …

The Efficacy Of Cbt In Treating Co-Morbid Anxiety And Depression In An Adolescent Client, Ryan J. Fischer

Theses and Dissertations

The goals of this exploratory investigation were to, (a) determine the efficacy of CBT in treating an adolescent client (n = 1) with co-morbid anxiety and depression, and (b) to examine whether or not the treatment of the anxiety disorder had an impact on the co-morbid depressive disorder. The investigation implemented quantitative measures such as the OQ-45.2, Y-OQ 2.0 and the WAI to evaluate the client's symptom impairment and the strength of the therapeutic alliance throughout treatment. The data indicated that the client's anxiety decreased over the course of treatment. In addition, the data indicated that the client's depressive symptoms …

Female Hormonal Influences On Stress- And Drug-Induced Reinstatement Of Extinguished Amphetamine-Induced Conditioned Place Preference, Melissa Elaine Bleile

Dissertations

One Animal paradigm used to study addiction is conditioned place preference. CPP is achieved when an animal develops a preference for environmental stimuli previously paired with subjective effects of a rewarding drug. Women may experience greater drug sensitivity than men, most likely due to estrogen levels. The purpose of this experiment was to assess the effects of female sex hormones on drug sensitivity and their interaction with the primary factors causing relapse, stress or drug re-exposure. Female rats were ovariectomized and received replacement hormones to control circulating hormone levels. These groups of animals were tested for amphetamine (AMPH)-induced CPP and …

Violence From Self-Love: Narcissism And Aggression In The Face Of Ego Threat, Ashley Girgis

Psychology Honors Theses

The current study examines the relationship between narcissism and aggression. The link between narcissistic personalities and heightened aggressive response to ego threat has been substantiated in the literature (Twenge & Campbell, 2003), but it is unclear whether this response is driven by a self-repairing mechanism to restore damaged self-esteem or by an ego-promoting mechanism to vent frustration at not being admired. These mechanisms were tested by giving narcissists either mistaken public ego threats or negative feedback. Results replicate the link between narcissism and aggression but do not point to one mechanism over the other; additional data, however, provide information about …

Stress And Health Behavior Among College Students, Lindsey Dorflinger

Honors Theses

The effect of stress and gender on health behavior, as well as the association amongst health behaviors, was examined. Past research has shown that stress can lead to higher levels of abnormal eating behaviors and attitudes, lower levels of exercise participation, and increased risk of smoking; studies have shown some gender differences as well. Seventy-eight college students completed questionnaires about stress, disordered eating, physical activity, and smoking status. Results showed that higher levels of stress were associated with higher levels of disordered eating, and that females have more abnormal eating attitudes and behaviors than males. Higher levels of exercise are …

Age Group And Gender Differences In Fears Of Aging, Vicky C. Tomlin

Theses and Dissertations

The purpose of this study is to investigate differences in fears of aging in two age groups (M=20 years and M=30 years) and gender differences in fears of aging. Two hundred twenty-two undergraduate (n=156) and graduate students (n=66) responded to three questionnaires, the Anxiety about Aging Scale (AAS), the Brief Life Satisfaction Scales (BLSS), and an open-ended questionnaire allowing participants to write in their five greatest personal fears of aging. The older age group had significantly higher Anxiety about Aging Psychological Concerns subscale scores. Males scored significantly higher than females in AAS total …

Self-Deception And Other-Deception In Personality Assessment: Detection And Implications, Mary Lynn Starke

Dissertations

The present study utilized multiple methods of detecting self-deception and other-deception and explored potential implications for organizations hiring individuals exhibiting these tendencies. Participants were 242 undergraduate business students who completed self-ratings of extraversion and agreeableness under both ¿answer honestly¿ instructions and ¿answer as if you are applying for a job¿ instructions. Additionally, they completed the impression management and self-deceptive enhancement scales of the BIDR, the fake good scale and the good impression scale of the CPI, and took part in a role play with a trained observer. Individuals who knew the participants well provided ratings of participants¿ adjustment, integrity, interpersonal …

The Effects Of Speech Rate On Comprehension, Jamilah Adams, Michelle Weber

Undergraduate Psychology Research Methods Journal

There is a perception that the rate of speech affects the level of comprehensibility of a listener. If the rate of a speaker during a speech or lecture does in fact affect the level of comprehension, then the speaker would have to modify his/her rate of speech in order to benefit the ears of all his/her listeners. In the present study, 40 participants listened to four passages, taken from www.testpreview.com all recorded at varying speeds, after which they answered 10 questions that corresponded with the passages. Results found that speech rate had no effect on comprehension. However, findings based on …

An Examination Of The General Mobility Of Older Adults Based On Late-Life Depression And Its Treatment, Heather Kossick

Masters Theses & Specialist Projects

Older adults experience a variety of cognitive and physical declines as they age. Consequently, these changes can impact mobility and mental health (i.e., depression). Studies have suggested a relationship between driving habits changes (in particular, driving cessation) and depression (Fonda, Wallace & Herzog, 2001; Marottoli et al., 1997). Very little research has been conducted to examine the relationship between depression and other mobility changes in treated and untreated community dwelling older adults. Older drivers who ranged in age from 65 to 91 with a mean age of 73 completed the Center for Epidemiologic Studies Depression Scale (CES-D) (Radloff, 1977), Life …

Developmental And Gender Patterns In Social Information Processing: Social Problem-Solving And Social Goals, April Bowersox

Masters Theses & Specialist Projects

The purpose of this study was to examine patterns of development and gender in first- through fifth-grade children's (N = 514) social information processing, as well as the role emotion plays in these patterns. Developmental patterns and goal selection have been relatively understudied in past social information processing literature. Videotaped ambiguous provocations were presented in which provocateur's emotion displays were manipulated (two each of happy, angry, and sad); children imagined being the provocateur's victim. Results revealed age and gender differences in children's goal selection and social problem-solving. Provocateur's emotion displays were also found to Influence goal selection and problem-solving in …

Gender, Occupational Position, And Incivility: The Role Of Status On Rude Behaviors At Work, Sherri Settle

Masters Theses & Specialist Projects

This study examined the role of status (i.e., occupational position and gender) in the frequency and experience of workplace incivility. Participants were 89 university students over the age of 20 who currently were employed and completed measures assessing their experiences of incivility at work, the instigator of the incivility, and jobrelated outcomes (i.e., turnover intent, job satisfaction, and organizational commitment). Consistent with hypotheses, supervisors were more likely to be instigators of incivility than coworkers. Participants also reported lower job satisfaction when the instigator was a supervisor, and lower organizational commitment and higher turnover intent when the instigator was male. These …

Possible Undue Stress Factors On Graduating Seniors, Steven L. Hahne

Undergraduate Psychology Research Methods Journal

The purpose of this study is to determine whether the hypothesis of the experiment is true, which was to find if the student body thinks that a policy to which the graduating seniors must turn in all graded work two weeks before the final exam is fair. It also offers a chance for the student body to voice opinions or suggestions in an open and anonymous questionnaire format. Fifty students chose to partake in a questionnaire that included questions about the university’s policy. They were divided into two groups: one group had twenty-three students [freshman and sophomores] of Human Subject …
