Profile of the Youth Self-Report Among South Texas Adolescents and the Potential Relationship to Pesticide Exposure (open access)

Profile of the Youth Self-Report Among South Texas Adolescents and the Potential Relationship to Pesticide Exposure

The potential for human exposure to pesticides exists particularly for agricultural workers (i.e. migrant workers) and individuals within close proximity to pesticide-sprayed crops (i.e. those living on or near agricultural farms). Children, through biology and behavior, may be more susceptible and vulnerable to exposure to pesticides than adults. The purpose of this study was to examine young populations particularly at-risk for occupational or accidental exposure to pesticides and determine associated behavioral, emotional, and physical symptoms. A total of 444 students from two South Texas school districts completed questionnaires assessing level of risk of exposure to pesticides and were categorized into at-risk and low risk categories. Physical, emotional, and behavioral symptoms were obtained using the Youth Self-Report. Children who were at-risk demonstrated significantly higher scores on the Youth Self-Report (YSR) in the areas of anxious/depressed, attention problems, social problems, somatic complaints, thought problems, withdrawal, internalizing behaviors, and total problem behaviors than children who were at lower risk of pesticide exposure. Odds ratios were obtained and suggested that children in the at-risk category were more five times more likely to score in the clinically significant range on the Attention Problems subscale, and three times more likely to score in the clinically significant …

Measuring Change in University Counseling Center Students: Using Symptom Reduction and Satisfaction with Services to Propose a Model for Effective Outcome Research

Access: Use of this item is restricted to the UNT Community
Abstract This study proposes a model for meeting increasingly mandated outcome research objectives in a university counseling center setting. It is proposed that counseling centers utilize their existing intake forms, along with an annual satisfaction survey to determine the effectiveness of counseling services. Effectiveness is defined as improvement and measured by the reduction of the symptoms or presenting concerns with which the client initially presented. It also introduces the Relative-Change Index (R-Chi) as an objective way to quantify intra-individual change occurring as a result of therapy. This new mathematical procedure allows for a more meaningful assessment of the client's degree of improvement, relative to their potential for improvement. By re-administering the problem checklist, routinely included as part of the initial paperwork for each client at intake, again post-therapy, it is possible to quantify improvement by measuring the difference in distressing concerns. Additionally, including a subjective, retrospective survey question asking the client to indicate their perceived rate if improvement at follow-up provides construct validity and allows for correlational comparisons with R-Chi. Results suggest that student/client ratings of the degree to which the services they received satisfactorily addressed their presenting concerns were significantly rated to their R-Chi score. This model suggests that …

Measurement of Adolescent Psychopathy: Construct and Predictive Validity in Two Samples of Juvenile Offenders (open access)

Measurement of Adolescent Psychopathy: Construct and Predictive Validity in Two Samples of Juvenile Offenders

The construct of psychopathy holds promise as a discriminating variable in the classification and explanation of childhood antisocial behavior. The new generation of psychopathy measures, designed to measure this construct in adolescent populations, must meet acceptable standards of reliability and validity prior to the clinical application of the construct with adolescent offenders. The purpose of this study is to examine the construct and predictive validity of adolescent psychopathy as measured by the PCL:YV, PSD, SALE, and SRP-II. Data from two samples of detained adolescent offenders (short-term and long-term detention) are utilized to investigate construct validity via MTMM. In addition, external validity indices including institutional violations (fighting, seclusions, and treatment refusals) and community supervision (probation contacts, drug testing, and re-arrests) are operationalized and measured in order to examine the predictive validity of adolescent psychopathy. Results of construct validity offer modest support for the two-factor model of psychopathy. For external validity, Factor 2 accounted for greater variance in the prediction of institutional infractions and subsequent placements in a secure facility; however, its overall predictive validity was low. The results suggest that the current measures assess psychopathic traits and behaviors which may be stable in adults but are likely to be normative and …

The Relationship of False Self Behavior to Object Relations, Attachment, and Adjustment (open access)

The Relationship of False Self Behavior to Object Relations, Attachment, and Adjustment

The focus of this investigation is to assess the relationship between false self behavior, object relations and attachment variables, and adjustment. Theory suggests that object relations and attachment are interrelated, and have been independently linked to psychological consequences. Theory also postulates a relationship between false self behavior and object relations theory. Given the interrelatedness of object relations and attachment theory it is possible that false self behavior may also be linked to attachment variables. While the relationship between object relations and false self behavior seems to have been established object relations theory and attachment theory have not been studied in tandem as related to false self behavior. In addition, this investigation will explore the relationship of adjustment variables to attachment and object relations variables. Undergraduate males and females will be solicited for participation, and will be asked to complete self-report questionnaires measuring false self behavior, object relations, attachment, and adjustment. The primary research hypothesis is that less false self behavior will be related to mature object relations, secure attachment, and fewer symptoms.

Performance of Adults With and Without Attention-Deficit/Hyperactivity Disorder (ADHD) on Measures of Response Inhibition and Frontal Lobe Functioning (open access)

Performance of Adults With and Without Attention-Deficit/Hyperactivity Disorder (ADHD) on Measures of Response Inhibition and Frontal Lobe Functioning

In this study 2 groups of adults, those with and without ADHD, were studied in terms of cognitive functioning and symptoms of ADHD, depression, anxiety, and substance abuse. Due to the difficulties in diagnosing ADHD in this population three methods of diagnosis were used and the resulting findings presented. The groups did not differ in measures of depression, anxiety, substance abuse or age. Those adults who met criteria for ADHD showed worse performance on a measure of response inhibition compared to those without ADHD. The patterns of correlations among the cognitive measures differed between the two groups. The conclusions from the findings are discussed in relation to Barkley's (1997) self-regulation model of ADHD.

Psychological and Sociodemographic Predictors of Psychological Distress in BRCA1 and BRCA2 Genetic Testing Participants within a Community Based Genetic Screening Program

Access: Use of this item is restricted to the UNT Community
Mutations in BRCA1 and BRCA2, the first two breast cancer susceptibility genes identified, carry as much as an 85% lifetime risk of developing breast, ovarian or other cancers. Genetic testing for mutations in these two genes has recently become commercially available. There have been varying amounts of psychological distress noted among women with a family history of breast cancer. Distress has been observed to impact psychological functioning, activities of daily living, and the practice of breast cancer surveillance behaviors. Within the genetic screening process, psychological distress has been shown to impact the decision to undergo genetic screening, the comprehension and retention of risk assessment information, as well as affecting the subject following the receipt of the genetic test results. Little work has been done to examine predictors of distress within at risk subjects. This study examines psychological distress among 52 community women presenting for BRCA1 and BRCA2 genetic mutation testing. Predictors of distress included family cancer history, education, age, Ashkenazi ethnicity, and Internality and Powerful Others Health Locus of Control. Vulnerable sub-groups of patients include younger women, women with higher levels of education and women of Ashkenazi ethnicity.

Assessment of the Effects of Interpersonal Openness and Coping Resources on the Psychological Sequelae of Traumatic Victimization (open access)

Assessment of the Effects of Interpersonal Openness and Coping Resources on the Psychological Sequelae of Traumatic Victimization

The present study tested a model addressing whether interpersonal Openness and interpersonal and intrapersonal Coping Resources mediated the relationship between interpersonal Victimization and the Psychological Symptoms women experience as a result of these traumas. Victimization indicators (physical violence, sexual assault, psychological abuse, and revictimization), Coping indicators (optimism, self-esteem, private self-consciousness, social network and therapy), Openness indicators (self-silencing, communal orientation, trust, self-monitoring, and network orientation), and Psychological Symptoms indicators (global distress, dissociation, and suicidal ideation) were examined separately for African American (n = 245), Euro-American (n = 185), and Mexican American (n = 202) women. Structural Equation Modeling revealed that for African American and Euro-American women, Openness partially mediated the victimization-distress relationship. The model for Mexican Americans was the most complex with Openness and intrapersonal Coping fully mediating the psychological effects of victimization. Approximately 50% of the variance in psychological symptoms resulting from victimization was predicted by this model for African American and Euro-American women; over 80% of the variance was predicted for Mexican Americans. Thus, the importance of Openness to relationships in alleviating the psychological sequelae following interpersonal victimization was underscored by the results. Similarities and differences between these models are discussed. Implications of the results for future research and …

Effects of Self-Monitoring and Monetary Reward on Fluid Adherence among Adult Hemodialysis Patients (open access)

Effects of Self-Monitoring and Monetary Reward on Fluid Adherence among Adult Hemodialysis Patients

The effects of a monetary reward and self-monitoring on reducing interdialytic weight gain (IWG) were compared for 6 hemodialysis patients in an outpatient setting. A single-subject experimental design (A-B-BC-B-BC) was used to examine each variable individually and in combination, with alternating phases to control for possible sequencing effects. Monetary reward (50 cents - $3) was administered in a titrated manner according to standardized criteria, ranging from 3 % and 4% of patients' dry weight on weekdays and weekends, respectively, to 3.5% and 4.5% for weekdays and weekends. Self-monitoring involved recording daily fluid and diet intake. Results indicated that by the end of the treatment program, the 6 participants averaged a 14% reduction in weekday IWG and a 15.45% reduction in weekend IWG; however, due to significant variability, it cannot be concluded that the reductions are treatment effects. Four out of 6 participants reduced their average IWG for both weekends and weekdays by .75 kg (1.65 lb.). The average weekend reduction for these 4 participants was .85 kg (1.87 lbs.) while the average weekday reduction was .65 kg (1.43 lb.). All 6 participants showed reductions in weekday IWG that averaged .53 kg (1.17 lb.). However, only 2 participants demonstrated IWG reductions …

The uninvestigated factors: Dimensions of personality and psychopathology in sex offenders

Understanding the relation between personality characteristics, psychopathology, and sexual offenses can contribute to developing more effective treatment interventions. Previous research with sex offenders has focused on general personality traits or inconsistently classified sex offenders based on psychopathology. It was hypothesized that combining personality and psychopathological traits can assist in understanding sex offenders. The current study evaluated 88 male sex offenders in a court-mandated outpatient treatment program utilizing the NEO-PI-R and the MMPI-2. Three clusters of child molesters were examined for differences in personality characteristics and number of offenses. A second-order principle axis factor (PAF) analysis of personality and psychopathology traits revealed three factors: Psychological Distress, Excitement-Seeking, and Social Desirability. The potential clinical utility of these dimensions in predicting treatment compliance is examined.

Response Guided Errorless Learning with Normal Elderly (open access)

Response Guided Errorless Learning with Normal Elderly

This study investigates the use of response guidance for errorless learning of a perceptual motor task in normal elderly. It provides normative data for a study with stroke patients using this technique for cognitive rehabilitation. While errorless learning has been shown to be more effective on most tasks than trial and error learning for people with memory impairments, its use with normal individuals has received limited attention. The questions of interest were whether errorless training of the perceptual motor task was more effective for improving and retaining accuracy; and whether both accuracy and response speed were more resistant to the effects of increased cognitive demands. A sample of 43 normal elderly in the United Kingdom, ranging in age from 60 to 77, completed an assessment of intelligence, memory, and attention. They then received training, over two sessions one week apart, to mark the midpoint of Judd Arrows presented on a computer screen using a cross cursor moved by an active force feedback joystick (AFF). During training the errorless group received AFF guidance to the correct midpoint, while the errorful group received none, and both received auditory and visual knowledge of results. There was no AFF during baseline or post test …

Multiple Predictors of College Adjustment and Academic Performance for Undergraduates in Their First Semester (open access)

Multiple Predictors of College Adjustment and Academic Performance for Undergraduates in Their First Semester

College success, as defined by adjustment to college and academic performance, is a multidetermined with a number of contributing influences, including academic factors, personality variables, family characteristics, and environmental factors. This study attempted to provide an organizing model of the college success literature that was based on previous research (e.g., Aspinwall & Taylor, 1994) and current stress-coping theory (Moos & Swindle, 1990). Structural equation modeling analyses indicated that the hypothesized model did not fit the data well. However, subsequent regression analyses did validate the view that college success is multidetermined. Specifically, academic performance was predicted by a combination of academic factors (SAT score and class rank) and academic adjustment. In turn, academic adjustment was predicted by locus of control, perceived social support, and high school class rank. Personal adjustment was predicted by coping strategies employed, parents who fostered autonomy, locus of control, self-esteem, and high school class rank. Finally, social adjustment was predicted by optimism, coping strategies employed, and locus of control. Treatment implications as well as directions for future research were discussed.

Masculine Gender Role Conflict and Psychological Well- Being: A Comparative Study of Heterosexual and Gay Men

Masculine gender role conflict (MGRC) occurs when externally-imposed male gender role expectations have a negative impact on and consequences for men. The purpose of this study was to examine how men in a homogeneous setting (i.e., a college campus) compare on MGRC and psychological well-being, based on their self-identified sexual orientation. Utilizing canonical correlation analysis, 96 heterosexual men and 102 gay men were compared on four factors of MGRC (conflict between work and family, restrictive emotionality, restrictive affectionate behavior between men, and success, power, and competition) and five factors of psychological well-being (anger, anxiety, depression, self-esteem, and attitudes toward seeking psychological help). Findings for the heterosexual men were highly consistent with previous studies on MGRC and psychological well-being in a college-age population. Findings for the gay men indicated they had more problems with MGRC and psychological well-being than college-age and older gay men surveyed in the one published study on gay men and MGRC. Gay men who were single also reported more problems with restrictive emotionality, anger, anxiety, and depression, and had lower self-esteem, than gay men who were in a relationship. Between group differences were few, with gay men reporting significantly less restrictive affectionate behavior between men than heterosexual …

Assessment of Psychopathy in Incarcerated Females (open access)

Assessment of Psychopathy in Incarcerated Females

Psychopaths constitute only an estimated 1% of the population, yet they are responsible for a disproportionately large number of violent and nonviolent crimes. The literature addressing this syndrome among male offenders is quite extensive. In contrast, psychopathy and its underlying factor structure remains understudied among female offenders. Research has suggested marked gender differences in the prevalence, clinical characteristics, and underlying dimensions of psychopathy. This study examined the dimensions of psychopathy in a female offender sample. The Psychopathy Checklist-Revised and the Self Report Psychopathy-II (SRP-II) were administered to 119 female inmates at Tarrant County Jail in Fort Worth, TX. Confirmatory factor analyses of the Psychopathy Checklist-Revised (PCL-R) did not support the use of the traditional two factor male model or a recently proposed two- factor female model. This thesis also addressed females' self-appraisal of PCL-R Factor 1 characteristics as well as the usefulness of the self-administered Self-Report Psychopathy-II as a screen for psychopathy.

Psychological Hardiness and Biochemical Markers of Acute Stress (open access)

Psychological Hardiness and Biochemical Markers of Acute Stress

The establishment of physiological norms for psychologically hardy vs. non-hardy individuals was attempted by examination of levels of salivary cortisol and urinary norepinephrine before and after a mid-term examination stressor. Normative data was collected on the reported frequency of stressors and their severity one week prior to the examination, and self-reported ratings of stress immediately prior to the examination. Performance on the examination as a function of hardiness was explored. Associations between demographic variables and psychological hardiness were also studied. Results from this study were inconclusive in establishing physiological norms for psychologically hardy individuals. Associations were found between: 1) hardiness and frequency of stressors; 2) hardiness and age; and 3) self-reported ratings of stress and anxiety as measured by the State-Trait Anxiety Inventory (STAI).

Differentiating Connectedness and Neediness as Two Forms of Dependency (open access)

Differentiating Connectedness and Neediness as Two Forms of Dependency

The Depressive Experiences Questionnaire Dependency scale has been used extensively by researchers to measure a personality style vulnerable to depression. However, subsequent studies have demonstrated that the DEQ-Dependency is composed of two distinct forms of dependency, "Connectedness" and "Neediness", which may have different implications for mental health. While Connectedness may represent a more mature form of dependency than Neediness, it may not represent an entirely "healthy" form of relatedness as previously suggested. Although these scales are being used in current research, it is not yet clear what they represent. One goal of the present study was to further examine the construct validity of Connectedness and Neediness in order to differentiate these constructs. Gender, self-efficacy, relationship quality, and interpersonal behavior were chosen because of their proposed significance in differentiating forms of dependency. 265 undergraduates completed the DEQ, Beck Depression Inventory (BDI), the Mutual Psychological Development Questionnaire (MPDQ), and the Inventory of Interpersonal Problems (IIP). Overall, results supported the importance of distinguishing between these two factors of dependency. Neediness was associated with more maladaptive correlates for both genders. The picture is more complex for Connectedness, however, and it appears that Connectedness is less healthy for women than for men.

Relations between Child Molesters' Self-Perceptions and Treatment Engagement (open access)

Relations between Child Molesters' Self-Perceptions and Treatment Engagement

Researchers emphasize the role of cognitions in sex offenders' molesting behaviors. Although cognitions are important, little research has examined child molesters' thoughts about themselves in relation to their engagement in treatment. In this study, the NEO-Personality Inventory (NEO-PI-R) was administered to 67 child molesters. Child sexual offenders rated themselves and their view of a typical child molester using two NEO-PI-R versions. The degree to which child sex offenders identify themselves with their view of a typical child molester, and this agreement's relation with engagement in treatment, were investigated. The view that child sex offenders hold about themselves in relation to a typical child molester showed no relation to treatment engagement or length of time in treatment. However, this self-perception was related to the number of children abused.

The relationships between insight, psychopathological symptoms, and neurocognitive function in psychotic disorders.

Many psychotic patients fail to admit they are mentally ill. The current study evaluated the associations between insight, specific symptoms, and neurocognitive impairments. Thirty-three acute inpatients with a schizophrenia, schizoaffective disorder, or psychotic disorder NOS diagnosis were rated on the SAIE, Birchwood's IS, and the BPRS. Neurocognitive assessments of attention and frontal lobe functioning were also conducted. Stepwise multiple regression analyses found composites representing delusions, disorganization, and anxiety/depression, as well as CPT-IP shapes hit rate, served as significant predictors of total insight or the specific insight dimensions. At least for acute patients, symptoms tended to have stronger relationships with and were more regularly predictive of insight than neurocognitive measures, though the attentional task associated with right hemisphere functioning, contributed significantly.

Automaticity and Hemispheric Specialization in Emotional Expression Recognition: Examined using a modified Stroop Task

The main focus of this investigation was to examine the automaticity of facial expression recognition through valence judgments in a modified photo-word Stroop paradigm. Positive and negative words were superimposed across male and female faces expressing positive (happy) and negative (angry, sad) emotions. Subjects categorized the valence of each stimulus. Gender biases in judgments of expressions (better recognition for male angry and female sad expressions) and the valence hypothesis of hemispheric advantages for emotions (left hemisphere: positive; right hemisphere: negative) were also examined. Four major findings emerged. First, the valence of expressions was processed automatically (robust interference effects). Second, male faces interfered with processing the valence of words. Third, no posers' gender biases were indicated. Finally, the emotionality of facial expressions and words was processed similarly by both hemispheres.

Psychological correlates of eating disorders: Exploring the continuum perspective.

Psychological and behavioral characteristics of female undergraduates with varying levels of disordered eating, as measured by the Questionnaire for Eating Disorder Diagnoses (Q-EDD; Mintz, O'Halloran, Mulholland, & Schneider, 1997), were investigated. Results suggest that the Q-EDD is an appropriate instrument for measuring eating disorder symptomatology. Greater disordered eating was associated with more bulimic, dieting, and weight fluctuation symptoms, higher impression management and approval-seeking needs, more dichotomous thinking, self control, and rigid weight regulation, and increased concern with body shape and dissatisfaction with facial features. Eating-disordered and symptomatic women evidenced more severe eating disorder behaviors and psychological distress than asymptomatic women. Findings are congruent with a redefined discontinuity perspective of eating disorder symptomatology. Treatment implications and campus-wide preventions are suggested.

Adolescent Psychopathy in an Adjudicated Male Population: The Role of Sensation Seeking, Impulsivity, and Externalizing Disorders (open access)

Adolescent Psychopathy in an Adjudicated Male Population: The Role of Sensation Seeking, Impulsivity, and Externalizing Disorders

Psychopathy, as conceptualized by Cleckley (1941), describes a constellation of psychological and behavioral correlates including superficial charm, untruthfulness, lack of remorse or shame, poor judgment, and failure to learn from experience. Based on Cleckley's initial work, Hare (1991) developed a two-factor model of psychopathy. The purpose of this study was to investigate the roles that sensation seeking, impulsivity, ADHD, conduct disorder, and oppositional defiant disorder have on adolescents classified as psychopaths. The participants consisted of 79 adjudicated male adolescents in a maximum-security facility. As hypothesized, adolescent male psychopaths had higher levels of sensation seeking, impulsivity, conduct disorder and oppositional defiant disorder. A discriminant function analysis found that sensation seeking, impulsivity, ADHD, Conduct Disorder, and Oppositional Defiant Disorder was moderately useful in classifying adolescent psychopathy. The results suggest that behavioral dysregulation is an important aspect of adolescent psychopathy. The relationship of these data to theories of adolescent psychopathy is discussed.

The relationship of personality traits to depression in a geriatric population. (open access)

The relationship of personality traits to depression in a geriatric population.

In later life, adverse life events, disability, health problems, inadequate social support, and personality traits hypothesized to be important risk factors for depression. Sample included 35 older (65-84) physical rehabilitation patients in a large metropolitan hospital. Statistical analysis included Pearson Product Moment correlations and multiple regression results. Perceived physical health, instrumental ADLs, life satisfaction, extraversion, and conscientiousness are inversely related to depressive symptom severity; neuroticism is positively related to depressive symptom severity. Regression models predicted depressive symptom severity, PANAS negative effect and PANAS positive affect. Neuroticism, insrumental ADLs, and age are significant predictors of depressive symptom severity; neuroticism and age are signficant predictors of PANAS negative affect, while extraversion is a significant predictor of PANAS positive affect. Personality factors, level of functioning, and age are important factors relating to mood. Limitations of this study include: small sample size with special characteristics (high level of SES); incomplete personal and family history of psychiatric problems; and lack of clinical comparison sample.

The study examined the extent to which various cognitive dimensions are tapped by this battery in a heterogeneous geriatric sample of 114 patients with cognitive impairments. The proposed six-factor model of cognitive functioning has not been supported. Further exploratory factor analysis arrived at a five-factor solution. Factor pattern of the 23 tests supported the following five dimensions: memory, executive control, attention, visuospatial abilities, and cognitive flexibility.
