Cognitive And Psychiatric Predictors To Psychosis In Velocardiofacial Syndrome: A 3-Year Follow-Up Study, Kevin Antshel, Robert Shprintzen, Wanda Fremont, Anne Higgins, Stephen Faraone, Wendy Kates

Robert J. Shprintzen

Objective: To predict prodromal psychosis in adolescents with velocardiofacial syndrome (VCFS). Method: 70 youth with VCFS, 27 siblings of youth with VCFS and 25 community controls were followed from childhood (Mean age = 11.8 years) into mid-adolescence (mean age 15.0 years). Psychological tests measuring intelligence, academic achievement, learning/memory, attention and executive functioning as well as measures of parent and clinician ratings of child psychiatric functioning were completed at both time point. Results: Major depressive disorder, oppositional defiant disorder, and generalized anxiety disorder diagnoses increased in the VCFS sample. With very low false positive rates, the best predictor of adolescent prodromal …

Explaining The Longitudinal Association Between Puberty And Depression: Sex Differences In The Mediating Effects Of Peer Stress, Colleen Conley, Karen Rudolph, Fred Bryant

Colleen S. Conley

This research investigated whether exposure to peer stress serves as one pathway through which pubertal development contributes to depression over time, differentially for girls and boys. Youth (N = 149; 9.6–14.8 years) and their caregivers provided information at two waves, 1 year apart, on puberty (Wave 1), peer stress (occurring between Waves 1 and 2), and depression (Waves 1 and 2). Structural equation modeling analyses examined sex differences in the extent to which peer stress mediated the impact of pubertal status and timing on subsequent depression (i.e., tests of moderated mediation). Significant sex-moderated mediation was found for both pubertal status …

Measurement Invariance Of The Kidney Disease And Quality Of Life Instrument (Kdqol-Sf) Across Veterans And Non-Veterans, Karen Saban, Fred Bryant, Dominic Reda, Kevin Stroupe, Denise Hynes

Fred B. Bryant

Background Studies have demonstrated that perceived health-related quality of life (HRQOL) of patients receiving hemodialysis is significantly impaired. Since HRQOL outcome data are often used to compare groups to determine health care effectiveness it is imperative that measures of HRQOL are valid. However, valid HRQOL comparisons between groups can only be made if instrument invariance is demonstrated. The Kidney Disease Quality of Life-Short Form (KDQOL-SF) is a widely used HRQOL measure for patients with chronic kidney disease (CKD) however, it has not been validated in the Veteran population. Therefore, the purpose of this study was to examine the measurement invariance …

A Client-Based Description Of Reflecting Team-Work In Family Therapy , David Brown

David C. Brown

Though the practice of reflecting team-work has a strong theoretical base there has been little research examining its actual use. What has been written is primarily based on the therapist's and/or supervisor's experience, rather than the client's. This dissertation describes clients' perceptions of two different strategies of reflecting team-work that emerged from interviews conducted and analyzed using a moderately structured ethnographic interview methodology. The primary results suggested that reflecting team-work was helpful in providing clients with different perspectives; that in-room teams should be used sparingly during early therapy; that teams should reflect at least twice in-session; and that a three-person …

Positive State Mindfulness: A Multidimensional Model Of Mindfulness In Relation To Positive Experience, Timothy Ritchie, Fred Bryant

Fred B. Bryant

The present research tested Langer’s theory of mindfulness in the context of positive experiences: positive state mindfulness. In Study 1 (N1 = 586, N2 = 415) confirmatory factor analyses indicated that a three-factor model (Focused Attention, Novelty Appreciation, Open-Ended Expectations) fit the data well and explained responses better than a one-factor model. In support of construct validity, Study 2 (N3 = 239, N4 = 126) suggested that each dimension had a different pattern of associations with unidimensional trait measures of mindfulness, savoring beliefs, trait absorption, uncertainty tolerance, need for structure, and need for cognition. Study 3 (N5 = 46) revealed …

Gene X Environment Effects Of Serotonin Transporter, Dopamine Receptor D4, And Monoamine Oxidase A Genes With Contextual And Parenting Risk Factors On Symptoms Of Oppositional Defiant Disorder, Anxiety, And Depression In A Community Sample Of 4-Year-Old Children, John Lavigne, Laura Herzing, Edwin Cook, Susan Lebailly, Karen Gouze, Joyce Hopkins, Fred Bryant

Fred B. Bryant

Genetic factors can play a role in the multiple level of analyses approach to understanding the development of child psychology. The present study examined gene-environment correlations and Gene x Environment interactions for polymorphisms of three target genes, the serotonin transporter gene, the D4 dopamine reactor gene, and the monoamine oxidase A gene in relation to symptoms of anxiety, depression, and oppositional behavior. Saliva samples were collected from 175 non-Hispanic White, 4-year-old children. Psychosocial risk factors included socioeconomic status, life stress, caretaker depression, parental support, hostility, and scaffolding skills. In comparison with the short forms (s/s, s/l) of the serotonin transporter …

How The Rat Turned White, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

This is the first in a three-part series on the use of animals in psychological research. In it, I describe how animals got into laboratories in the first place, and their purpose and life there. In the second, I will describe animal model research, the strategy whereby psychologists' develop nonhuman animal models to study human psychopathology. In the concluding piece, I will present a critique of this enterprise, using original data I gathered. The three articles are based on a forthcoming book, Animal Models of Human Psychology: Science, Ethics, and Policy.

A Rodent For Your Thoughts: The Animal Model Strategy In Psychology, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

In this second of three essays, I describe how the early modern psychologists adopted the strategy of further transforming rats and other species into models of human thought, feeling, and behavior, and, particularly, of disorders of these - in effect taking "a rodent for your thoughts." In the third essay I will provide a critique and empirically-based evaluation of animal model research. Here I indicate what the model strategy in the biomedical sciences, properly understand, is intended to achieve and how, by contrast, particular models are presented to the public and funding agencies. Finally, I describe how they are utilized …

Psychology's Use Of Animals: Current Practices And Attitudes, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

In this chapter, I present a psychology primer for the uninitiated, with special emphasis on psychology's uses of animals. After sketching the scope of the field generally, I review available data on present numbers and species of animals used in psychological research, level of suffering induced and current trends. I also provide several concrete examples of psychological research involving animals. Finally, the chapter concludes with a presentation of attitudes of psychologists toward animals and these practices.

The Ingrown World Of Animal Model Research In Psychology, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

In the previous essay, I described the proper function of models in science as heuristic, as a way of generating hypotheses about the actual object of study. Turning to animal models in psychology, I offered a general characterization of that enterprise using sham feeding, an animal model of the eating disorder called bulimia, as an example. In this final of three essays, I offer an evaluation of this animal model strategy that largely employs the tools of social science. I close with a recommendation and a prediction.

Understanding Dogs Through Kinesthetic Empathy, Social Construction, And History, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

The term, "come into animal presence," she takes from the title of a Denise Levertov poem. The poem, which reads, in part, "What joy when the insouciant armadillo glances at us and doesn't quicken his trotting across the track into the palm bush. What is this joy?" This joy is the possibility of our being in the presence of animals for "(t)he armadillo has some intention to pursue in the palm forest." This joy, to which I invite you here, consists in dwelling in that presence, in inhabiting that intention, that armored but guileless world of the armadillo. I will …

Social Motivation Is Associated With Elevated Salivary Cortisol In Boys With An Asd, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

Because social communication difficulties and stress are common in children with an ASD, and because it has been hypothesised that the two are related, the association between these two variables was investigated in a sample of 90 boys with an ASD and who were aged between 6 years and 12 years of age. The Social Responsiveness Scale (SRS) was completed by the parents of these boys about their sons, plus salivary cortisol samples were collected from the boys. Results indicated that only one aspect of the boys' SRS was significantly correlated with cortisol—Social Motivation (SM). Factor analyses revealed two discrete …

Age-Related Differences In The Association Between Stereotypic Behaviour And Salivary Cortisol In Young Males With An Autism Spectrum Disorder, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

To identify if age influenced the relationship between one of the central symptoms of Autism Spectrum Disorder (ASD) and physiological stress, the association between stereotypic behaviour (SB) and stress-related cortisol concentrations was examined in a sample of 150 young males with an ASD. Parent-rated SB was significantly correlated with cortisol concentrations for boys aged 6 years to 12 years but not for adolescents aged 13 years to 18 years. This age-related difference in this association was not a function of cortisol concentrations but was related to differences in SB across these two age groups. IQ did not have a significant …

Which Aspects Of Sensory Features Are Associated With Elevated Cortisol Concentrations In Boys With An Autism Spectrum Disorder?, Vicki Bitsika, Christopher Sharpley, Nicholas Andronicos, Linda Agnew, Richard Mills

Vicki Bitsika

Difficulties in Sensory Features (SF) have been included in the most recent diagnostic processes for Autism Spectrum Disorder (ASD) and are more common in children with an ASD than their non-ASD peers. In addition, these difficulties with SF have been suggested as causing elevated stress and concentrations of salivary cortisol in young people with an ASD. However, previous studies have not examined the specific aspects of SF that are associated with elevated cortisol and that was the focus of this study with 135 boys with an ASD aged 6–18 years. The boys’ mothers assessed their sons’ SF with the Sensory …

Differences In The Prevalence, Severity And Symptom Profiles Of Depression In Boys And Adolescents With An Autism Spectrum Disorder Versus Normally Developing Controls, Vicki Bitsika, Christopher Sharpley

Vicki Bitsika

The prevalence, severity and symptom profiles for major depressive disorder (MDD) were compared in samples of boys and adolescents with and without an autism spectrum disorder (ASD). Self-reports were obtained on the Depression subscale of the Child and Adolescent Symptoms Inventory (CASI-D) with 70 ASD and 50 non-ASD male participants between the ages of 8 and 18 from Queensland, Australia who were matched for age and IQ. Results indicated that the ASD participants had significantly higher total CASI-D scores, a greater proportion of participants who qualified for a diagnosis of MDD, and over 50% higher scores for 8 of the …

Eight-Month Test-Retest Agreement In Morning Salivary Cortisol, Self- And Parent-Rated Anxiety In Boys With An Autism Spectrum Disorder, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

The agreement over time in morning salivary cortisol concentrations and also self- and parent-rated anxiety was investigated in a sample of 16 boys with an ASD. Cortisol and anxiety data were collected eight months apart. Results indicated that there were significant correlations between each pair of measures from the two occasions, suggesting that cortisol concentrations and anxiety did not vary much at all over that time, challenging the assumption that cortisol needs to be measured over multiple days to obtain reliable data from children with an ASD. Implications for research into the ways these children respond to chronic stressors are …

Religiosidad Y Felicidad En Alumnos Universitarios: ¿Es Mejor Trabajar Con Los Ancianos?, T. L. Brink

T. L. Brink

Reports on self-estimated life satisfaction and religiosity (present and future projected) in different populations of Mexican university students. Student levels of life satisfaction were comparable to the national norms (Mitofsky) but were lower than the national norms for religiosity. Unlike in the U.S., there was no correlation between religiosity and life satisfaction. Students in a gerontology program showed higher levels of religiosity than those in another university.

A Dyadic And Longitudinal Investigation Of Adjustment In Couples Coping With Multiple Sclerosis. Research In Developmental Disabilities, Christina Samios, Kenneth Pakenham, Jill O'Brien

Christina Samios

Background Multiple sclerosis (MS) can affect adjustment at both the individual and couple level. Purpose This study examined differences and associations between MS patient and spouse adjustment, and whether one partner’s adjustment predicts the other partner’s adjustment over time. Methods A total of 160 couples at Time 1 and 98 couples at Time 2 completed questionnaires. Results Mixed-model ANOVAs found that patients reported poorer adjustment than their spouse on a range of adjustment indicators and that positive affect and relationship satisfaction declined over time for both patients and spouses. Intraclass correlations found that patient and spouse scores on all adjustment …

Pain In Aquatic Animals, Lynne U. Sneddon

Lynne Sneddon, PhD

Recent developments in the study of pain in animals have demonstrated the potential for pain perception in a variety of wholly aquatic species such as molluscs, crustaceans and fish. This allows us to gain insight into how the ecological pressures and differential life history of living in a watery medium can yield novel data that inform the comparative physiology and evolution of pain. Nociception is the simple detection of potentially painful stimuli usually accompanied by a reflex withdrawal response, and nociceptors have been found in aquatic invertebrates such as the sea slug Aplysia. It would seem adaptive to have a …

What Do Zebrafish Want? Impact Of Social Grouping, Dominance And Gender On Preference For Enrichment, Paul Schroeder, Soffia Jones, Iain S. Young, Lynne U. Sneddon

Lynne Sneddon, PhD

Although environmental enrichment is known to improve laboratory rodent wellbeing and enhance scientific data collection, relatively little is known with regards to the type of enrichment that might be useful for zebrafish (Danio rerio). Therefore, this study explored if zebrafish displayed preferences for a range of enrichments, including substrates, artificial plants, combinations thereof and airstones. Tanks divided into two compartments containing different enrichment cues were used to determine the preferences of zebrafish housed in pairs and groups of eight. When comparing time spent in enriched versus barren compartments, dominant individuals in a pair displayed a preference for substrate and behaviourally …

Use Of Complementary Therapies By Registered Psychologists: An International Study, Peta Stapleton, Hannah Chatwin, Emma Boucher, Sue Crebbin, Sandra Scott, Dean Smith, Gail Purkis

Peta B. Stapleton

Complementary and alternative medicine (CAM) is a category of diverse medical and health care systems, practices, and products that are not generally considered part of conventional medicine. However, the use of CAM by lay people is increasing worldwide. This study investigated the utilization pattern of CAM among registered psychologists, and level of training in delivering a CAM service. Psychologists (N = 193) participated from Australia, the United States, the United Kingdom, and New Zealand. Almost all (99.6%) respondents reported using at least 1 CAM service in the past, and 64.2% indicate they were trained to deliver at least 1 area …

Body Image Avoidance, Body Dissatisfaction, And Eating Pathology: Is There A Difference Between Male Gym Users And Non–Gym Users?, Peta Stapleton, Timothy Mcintyre, Amy Bannatyne

Peta B. Stapleton

With research highlighting the increasing prevalence and severity of body image and eating disturbances in males, particularly athletes and regular gymnasium users, the current study examined body image and eating disturbances in a sample of male gym users and non–gym users (N = 180). Based on previous research, it was predicted that male gym users would report greater body image disturbance (e.g., body image avoidance and body dissatisfaction) and eating pathology, compared with non–gym users. Results of the study partially supported hypotheses, revealing body dissatisfaction and eating pathology were significantly increased in male gym users. However, no significant differences were …

Psychosocial Moderators Of Perceived Stress, Anxiety And Depression In University Students: An International Study, Aileen Pidgeon, Stephanie Mcgrath, Heide Magya, Peta Stapleton, Barbara Lo

Peta B. Stapleton

Extensive research shows university students experience high levels of stress, which can lead to the development of mental health problems such as anxiety and depression. Preliminary evidence supports the role of psychosocial factors such as perceived social support (PSS) and campus connectedness (CC) as protective factors in the development of mental health problems in university students. However, research conducted on the potential ameliorating effects of social support on stress applying Cohen and Wills’ (1985) stress-buffering hypothesis produced weak, inconsistent, and even contradictory results. In addition, little attention has been given to examining the protective role of CC in the relationships …

Examining Characteristics Of Resilience Among University Students: An International Study, Aileen Pidgeon, Natasha Rowe, Peta Stapleton, Heidi Magyar, Barbara Lo

Peta B. Stapleton

Attending university is a particularly stressful time due to unique emergent stressors such as changes in environment, loss or diminishment of social support networks, academic pressures, developing peer relationships, and financial management. There is growing recognition that these common stressors may have deleterious effects on the mental health of students. Resilience, a personality characteristic that moderates the negative effects of stress and promotes adaptation, has been associated with increased psychological well-being. Despite a growing body of research on resilience and its clinical significance in preventing mental health problems, relatively little is known about contributing factors for resilience in well-adjusted university …

Should Educators Be ‘Wrapping School Playgrounds In Cotton Wool’ To Encourage Physical Activity? Exploring Primary And Secondary Students’ Voices From The School Playground, Brendon P. Hyndman, Amanda Telford

Dr Brendon P Hyndman

Physical activity in school playgrounds has changed considerably over recent decades to reflect a climate of ‘surplus safety’. A growing culture of surplus safety can be attributed to a desire of parents and teachers responsible for children to protect school students from danger. The aim of this research was to examine students’ perceptions of playground safety influences on physical activity during school breaks from the perspectives of the ‘users’ of school playgrounds. Data collection consisted of seven focus groups (4 primary school & 3 secondary school) conducted across four schools (2 primary & 2 secondary). During this study, the focus …

Pain Perception In Fish: Evidence And Implications For The Use Of Fish, Lynne U. Sneddon

Lynne Sneddon, PhD

Pain assessment in fish is particularly challenging due to their evolutionary distance from humans, their lack of audible vocalization, and apparently expressionless demeanour. However, there are criteria that can be used to gauge whether pain perception occurs using carefully executed scientific approaches. Here, the standards for pain in fish are discussed and can be considered in three ways: neural detection and processing of pain; adverse responses to pain; and consciously experiencing pain. Many procedures that we subject fish to cause tissue damage and may give rise to the sensation of pain. Fish are popular as pets, in animal exhibits, and …
