This study is part of a larger research project examining family attachment processes. The current study tests a family process model that postulates the mediating role of parent-child attachment and sibling relationship quality in the associations of parent psychopathology or marital adjustment to children's psychological dysfunction. A community sample of 86 families with at least one school-aged (8-12 years) child was recruited from area schools and organizations. Families came to the UNT Family Attachment Lab, where they participated in research tasks, including interviews, self-report instruments, and videotaped interaction tasks. Specific questionnaires used in this study included the Sibling Relationship Questionnaire, the Security Scale, the Behavior Assessment System for Children, the Symptom Assessment-45 Questionnaire, and the Dyadic Adjustment Scale. Using a single indicator for each variable, path analyses tested three paternal models, three maternal models, and three systemic models using different informants' (i.e., father, mother, child) reports of child functioning as the outcome variable. Results of this study highlight the positive relationship between parent marital adjustment and parent-child attachment security, as well as the inverse relationship between maternal psychopathology and mother-child attachment security. In addition, the inverse relationship between parent-child attachment security and child psychological dysfunction was significant across nearly all …

This study investigated the relationship among anxiety, depression, and sleep disturbances and the treatment of these three disorders through neurotherapy. Research suggests that these conditions commonly co-occur in the general population and that central nervous system (CNS) arousal may play a primary role in the development and maintenance of these disorders. Several recent studies suggested that neurotherapy, a biofeedback-based treatment for CNS dysregulation, might be an effective treatment for comorbid conditions, particularly the ones of interest here, depression, anxiety, and sleep disturbances. This investigation used a clinical case-series design to assess pre/post neurotherapy changes on objective measures of anxiety, depression, and sleep and to determine whether changes in anxiety and depression then predict improvements in sleep quality. Data for 23 participants (10 males) were obtained from files of adults (Mage = 40.22 years, SD = 16.20) who received at least 15 neurotherapy sessions (M = 47.83 sessions, SD = 22.23) the University of North Texas Neurotherapy Lab. Matched pair t-tests revealed that symptoms of sleep disturbance, depression, and anxiety showed significant improvements following neurotherapy. Neurotherapy treatment effect sizes generally ranged from moderate to large (d = .414 - .849). Multiple regression analysis found that changes in self-reported anxiety symptoms, but …

Freely choosing a life direction, or flexible valuing, is a core component of acceptance and commitment therapy (ACT). Initial research suggests that valuing behavior may contribute to psychological well-being, but has been stymied by a lack of an efficient measure. The current study examined the psychometric characteristics of a new measure of flexible valuing, the Meta-Valuing Measure (MVM), in a sample of 532 undergraduates. Exploratory factors analysis revealed 3 orthogonal factors, Valuing (α = .94), Freedom from Values Conflict (α = .92), and Flexibility in Valuing (α = .73). The majority of expected relationships with other constructs were significant including those with measures of values, mindfulness, quality of life, experiential avoidance, and psychological distress.

The current study aimed to examine the naturalistic relationship between physical activity and sleep by exploring frequency, type, and timing of exercise and their association with a variety of sleep variables (e.g., sleep onset latency, wake after sleep onset, sleep efficiency). Young adults (n = 1003) completed a variety of self-report questionnaires, including a week-long sleep diary and a survey of typical frequency, type, and timing of exercise completed in the past week. Increased frequency of physical activity was related to increased sleep efficiency (total sleep time/time in bed), decreased time in bed, and decreased time spent awake in bed in the morning. Greater amounts of exercise energy expenditure (i.e., metabolic equivalents) per week was related to increased sleep efficiency, and decreased time in bed and time spent awake in bed in the morning. After controlling for other factors, this relationship remained true only for time spent awake in bed in the morning. Early morning exercisers reported shorter total sleep time and time in bed than those who typically exercised at other times. No exercise differences were found between those who met the research diagnostic criteria for insomnia and those who did not. This study provides valuable information to help …

Deciding to exercise requires trade-offs between immediate and delayed benefits. These momentary decisions may be moderated by personality such that patterns of individual behavior emerge. The aim of the current study was to determine if higher levels of optimism and lower levels of delay discounting were related to exercise frequency. A sample of 360 undergraduate students completed a survey study related to understanding the choices made by undergraduates and how other factors relate to their decision-making. The survey included measures of optimism, delayed discounting, and self-reported exercise frequency in four domains: cardiovascular, resistance, sports, active lifestyle. Hierarchical linear regression was used to examine optimism and delay discounting as predictors of exercise frequency. Optimism and delay discounting were negatively correlated, but neither was related to exercise frequency. Furthermore, optimism and delay discounting were not significantly related to frequency spent in cardiovascular, resistance, or active lifestyle exercise. However, women scoring higher in delay discounting were more likely to participate in physical sports. The present study helps inform future research by showing potentially important psychosocial variables related to optimism, delay discounting, and exercise.

In this study, the relationship between formal training opportunities and internal promotions in organizations was examined in order to support the value of organizations investing in employees through training opportunities, as training is often seen as an expense to be cut in difficult times. Differences between general and specific training topics on the impact of frequency of promotion in an organization were addressed, as well as assessing differences between employees and managers. Training allows for a more capable workforce and pool of employees to pull from when an organization needs to hire. Hiring from within can save time, money, and allow for a proven person-organization fit that hiring from the external workforce cannot provide. The archival data used in the study were from the National Organizations Survey, 1996-1997 which included organizations of all sizes and forms. The analyses produced mixed support for the hypotheses. Significant relationships were found between hours of formal training and frequency of promotions of employees, and between importance of training in promotions and frequency of promotions for managers. Multiple regressions revealed that the hypothesis predicting that increased hours of training focused on general skills would positively contribute to promotion rates was not supported for either employees …

Performance on the Spatial Span subtest of the Wechsler Memory Scale has been viewed as an indicator of working memory and visuospatial processing. A number of factors including age and gender have been posited to effect performance on Spatial Span by older adults. The current study examined the impact of various forms of cognitive impairment and severity of impairment on Spatial Span performance. Five hundred thirty-eight individuals between the ages of 65 and 89 were evaluated in a university memory disorders clinic using a battery of neuropsychological tests that included Spatial Span. Participants were grouped by consensus diagnosis into type of cognitive impairment (Alzheimer's disease, vascular disease, amnestic mild cognitive impairment or non-amnestic mild cognitive impairment) or cognitively normal. As expected, an increase in severity of impairment results in a decrease in Spatial Span Total Score. Other findings included a weak relationship between age and Spatial Span Total Score. Gender, as well as age, did not fully account for the decline in Spatial Span Total Score. Spatial Span Forward score was not as good a predictor of severity in that reduction in score for Spatial Span Forward remains relatively stable regardless of level of impairment. Spatial Span Backward performance was …

The purpose of this study was to explore the effects of participants' abused or nonabused status as it interacted with their age and gender in producing different patterns of Hand Test responses as a function of the age or gender of the card. Participants, 61 young adults (M age = 23) and 60 older adults (M age = 73), were presented with the original Hand Test cards, as well as four alternate versions (e.g., young male, young female, older male, and older female). Expected effects varying by age, gender, and abuse status were not found. Results indicated main effects for participant abuse status, which were largely consistent with previous Hand Test research. Significant interaction effects were also found for participant age by participant abuse status (p < .05), as well as participant age by participant gender by participant abuse status (p < .05). An interaction effect was also found for Hand Test version by participant abuse status (p < .05), Hand Test version by participant age by participant abuse status (p < .05), as well as Hand Test version by participant gender by participant abuse status (p < .05). These results suggest that the alternate forms of the cards may …

Headache pain impacts most of the population at some point in life, at an enormous cost to day-to-day functioning. Determination of the variables that are associated with prevalence and severity of headaches has been inconsistent. One area that deserves more attention is the relationship between headaches and sleep. For instance, several sleep parameters may precipitate or exacerbate headaches, but previous research often used inconsistent and limited assessments of both headaches and sleep, making results difficult to interpret and compare. The current study seeks to extend previous research by using more comprehensive and empirically validated assessment techniques to study the relationship between sleep and headaches in a healthy sample. Greater self-reported sleep quality is related to lower headache frequency and severity, and lower self-reported sleep quality is characteristic of individuals having migraine-type headaches. Greater sleep efficiency is related to lower headache severity and shorter headache duration. Greater sleep onset latency is related to longer headache duration and greater headache severity. Greater number of nighttime awakenings is related to greater headache severity and is characteristic of individuals having a diagnosable headache disorder (either tension-type or migraine-type). Stress appeared to be a partial mediator between self-reported sleep quality and headache severity. Further experimental …

The purpose of this study was to examine whether Psychological Well-Being (comprised of self-esteem, optimism, satisfaction with life, and self-determination), perfectionism, body surveillance, and neuroticism moderated the relationship between body dissatisfaction and bulimic symptoms after controlling for social desirability and actual physical size. 847 female undergraduate students participated in the study. Participants completed an online questionnaire packet. An exploratory factor analysis determined that self-determination, optimism, self-esteem, and satisfaction with life loaded on to one factor representing Psychological Well-Being. Hierarchical moderated regression (HMR) was used to control for the influences of social desirability and body mass index on bulimic symptoms and then determine the main and interactive effects of body dissatisfaction and each moderator. Four variables (neuroticism, body surveillance, concern over mistakes, and doubts about actions) strengthened the relationship between body dissatisfaction and bulimic symptomatology, whereas Psychological Well-Being weakened the relationship. Parental expectations, parental criticism, and personal standards did not moderate the relationship between body dissatisfaction and bulimic symptomatology.

The study investigated an organized semantic fluency task, (the Controlled Animal Fluency Task - CAFT) as a measure of executive functioning (EF) in adults, and the relationship with instrumental activities of daily living (IADL). Participants (N = 266) consisted of a clinical sample (n = 142) utilizing neuropsychological assessment data collected at an outpatient psychological center, and a community sample (n = 124). The clinical sample was a heterogeneous mixed neurological group including a variety of health conditions and comorbid anxiety and depression. The CAFT Animals by Size demonstrated a significant positive correlation with Category Fluency (r = .71, n = 142, p < .001) , Animal Fluency (r = .70, n = 142, p < .001), and with other, established neuropsychological measures. The CAFT Animals by Size condition demonstrated a significant moderate negative correlation with IADL for the sample as a whole (r = -.46, n = 248, p < .001), and for the clinical sample (r = -.38, n = 129, p < .001), but not for the community sample. In a hierarchical regression analysis, CAFT Animal by Size explained additional variance in IADL (&#916;R2 = .15). In a hierarchical regression analysis predicting IADL with the control variables …

Malingering is the deliberate production of feigned symptoms by a person seeking external gain such as: financial compensation, exemption from duty, or leniency from the criminal justice system. The Test Translation and Adaptation Guidelines developed by the International Test Commission (ITC) specify that only tests which have been formally translated into another language and validated should be available for use in clinical practice. Thus, the current study evaluated the psychometric properties of a Spanish translation of the Structured Interview of Reported Symptoms (SIRS). Using a simulation design with 80 Spanish-speaking Hispanic American outpatients, the Spanish SIRS was produced reliable results with small standard errors of measurement (SEM). Regarding discriminant validity, very large effect sizes (mean Cohen's d = 2.00) were observed between feigners and honest responders for the SIRS primary scales. Research limitations and directions for future research are also discussed.

The acquirement of a disability (e.g., spinal cord injury, traumatic brain injury, amputation, multi trauma) is a risk factor for psychological disturbance (e.g., depression). Research has established that social support and secure attachment are protective factors against psychological disturbance. Attachment patterns have also been associated with differences in perceived social support. Secure attachment and higher perceived social support have been implicated in greater levels of resilience but need to be validated with a population of individuals who have acquired a disability. The Experiences in Close Relationships, Social Provisions Scale, Connor-Davidson Resilience Scale, Personal Health Questionnaire - 9 Depression Scale, and a Demographic were administered to 102 adult inpatients at a rehabilitation hospital undergoing an individualized rehabilitation program. Two MANOVAs were conducted to examine the direct associations of attachment classifications with the major dependent variables, as well as the various social support subscales. Path analysis tested two mediational models suggested by literature. Model 1 assessed the mediating role of attachment anxiety and attachment avoidance on the effect of social support on depression and resilience. Model 2 assessed the mediating role of social support on the effect of attachment anxiety or attachment avoidance on depression and resilience. Partial support was obtained for …

Structural equation modeling was used to examine how childhood sexual abuse (and other associated variables, such as family functioning and experiencing multiple forms of abuse) relates to revictimization and psychological distress. Participants were women who participated in Project HOW: Health Outcomes of Women interviews, a longitudinal study that spanned six waves of interviews. Only women with a history of childhood sexual abuse were included in the present study (n=178). Experiencing nonsexual child maltreatment in addition to childhood sexual abuse appears directly related to adult sexual and physical revictimization and indirectly related to psychological distress. Childhood sexual abuse alone was not predictive of revictimization or psychological abuse. This suggests that other mediating factors may explain the relation between CSA and revictimization found in other research. Clinical implications based on the results of the present study emphasize the importance of identifying children who have experienced multiple forms of abuse as particularly at risk for future victimization. In addition, providing interventions with a focus on education and empowerment might decrease risk for future violence and subsequent emotional maladjustment. Potential future research could examine the treatment outcomes and efficacy of these interventions as well as identify those mediating factors that increase the risk for …

This quasi-experimental study investigates neuropsychological functioning differences between 63 active duty soldiers who were placed into three groups (MTBI, PTSD, control) to provide better information for differentiating PTSD and MTBI. The ANAM and MicroCog were utilized to measure psychomotor speed, memory, and attention. Participants with PTSD performed worse on most measures of psychomotor speed and attention, and endorsed more symptoms of depression and anxiety when compared to MTBI and control participants. Further, attention appears to be the best cognitive domain for differentiating PTSD from MTBI, whereas memory variables did not differentiate these groups. Clinical and research implications of these findings are discussed.

Video game addiction often leads to a tremendous burden on those afflicted with the condition, draining their time, resources, and life away until they have nothing left. To further elucidate the problem of video game addiction, the current research examines the level of video game addiction of 111 participants, along with their motivation for their addictive behaviors, the quality of life of addicted individuals, and possible relations between video game addiction and other forms of addiction. Results of the current research indicate a correlation between addictive video game use and depression, alcohol use, a desire for escapism, a need for social interaction, and lack of self-control. The results of a multiple regression indicate that, amongst the various research factors, depression is the factor with the most significant link to addictive video game use, implying a dangerous correlation between mental health and an addictive behavior that some erroneously disqualify as a true addiction.

The efficacy of multidisciplinary inpatient and outpatient treatment for transitioning children with severe pediatric feeding disorders from gastrostomy tube dependency to oral nutrition was investigated utilizing caloric and fluid intakes as an outcome measure. The study involved 29 children ages 12 months to 5 years of age with gastrostomy tube dependency. Treatments were provided by speech therapists, occupational therapist, dietician and psychologist for a 30 day period. Four treatment groups were evaluated and average intakes compared at 4 observation periods including pretreatment, initiation of treatment, completion of treatment at 30 days and 4 month follow-up. Children receiving inpatient treatment for feeding disorders evidenced significant differences in oral caloric intake from pretreatment to discharge than outpatient treatment (p < .01) and wait list control group (p = .04). Oral caloric intake from discharge to 4 month follow up yielded no significant differences indicating treatment gains were maintained. Change in environment and caretaker showed a significant effect for the inpatient group (d = 1.89). Effects of treatment by age and weight at 4 month follow up were also analyzed.

About 8.3% of individuals diagnosed with diabetes mellitus (DM) are diagnosed with comorbid depression, a higher rate than the general adult population. This project examined the differences of depression symptoms experienced between diabetic and matched non-diabetic individuals and the relationship of daily activity and nutrition behaviors with depression between these groups. The 2005-2006 National Health and Nutrition Examination Survey (NHANES) was utilized to assess: depression symptoms, diabetic glycemic control as measured by glycoginated hemoglobin (HbA1c), amount of physical activity, percentage of macronutrients, daily frequencies of foods consumed, and the use of nutritional food labels to make food choices. A sample of diabetic (n = 451) and non-diabetic individuals (n = 451) were matched to on age, gender, ethnicity, and education. The diabetic individuals experienced greater depression on both continuous and ordinal diagnostic variables. Counter to expectation, there was no relationship observed between depression and HbA1c in diabetic individuals, r = .04, p > .05.

Despite high levels of exposure, firefighter posttraumatic stress disorder (PTSD) rates are unclear. Likewise, questions remain regarding how social interactions and beliefs about emotion might interact to influence PTSD in firefighters. In this study, U.S. urban firefighters (N = 225) completed measures of social support, negative social interactions, and fear of emotion which were then used via regression analyses to predict PTSD symptoms. Each independent variable predicted PTSD beyond variance accounted for by demographic variables. Additionally, fear of emotion emerged as the strongest individual predictor of PTSD and a moderator of the relation between social interactions and PTSD symptoms. These findings emphasize the importance of beliefs about emotion; both in how these beliefs might influence the expression of PTSD symptoms, and in how the social networks of trauma survivors might buffer distress.

Previous research suggests there are a number of variables that are associated with the expression of schizotypal personality disorder (SPD) symptoms. Such variables include childhood trauma, depression and anxiety, substance use, normal-range personality traits, ethnicity, and gender. However, research to date has not examined all of these variables in a single study to determine how they may be interrelated or differentially related to SPD symptom domains. Of particular interest is the association of these variables as explained by the diathesis-stress model. This study utilized a convenience sample of 298 undergraduate students to examine a continuous range of scores for symptoms of SPD and how the interrelation of biological factors such as gender and ethnicity and psychosocial factors and stressors such as childhood trauma and personality traits, specifically neuroticism and extroversion, influence the expression of SPD symptoms. It was predicted that anxiety, depression, stress, and childhood trauma would positively correlate to SPD symptoms. It was also hypothesized that neuroticism and substance use would positively correlate to schizotypal traits and extroversion would be negatively correlated to schizotypal traits as measured by the Schizotypal Personality Questionnaire-Brief. It was further hypothesized that psychosocial stressors would be moderated by the aforementioned biological factors.

Differences in Mexican American ethnicity, family and friend social support, and importance of diabetes self-management as related to diabetes management in the older adult population were evaluated with the University of Michigan Health and Retirement Study (HRS) 2003 Diabetes Study. Comparisons were made between Mexican Americans with Type II diabetes and similar non-Hispanic Caucasian and African American individuals with Type II diabetes. Neither family/friend social support nor importance of diabetes self-management were significant predictors of HbA1c levels. Results did not support the idea that perception of receiving support from family/friends or placing importance on diabetes self-management covaried with lower HbAlc level (family/friend: beta = -.13, t = -1.47, p = .143; self management: beta = .08, t = .55, p = .584).

The purpose of this study was to investigate psychological mechanism by which four intra- and inter-personal characteristics of an individual (anxious and avoidant adult attachment patterns, images of self, and religious faith) mediate the relationship between childhood trauma and each of three affect-behavior regulation problems in adulthood (symptoms of depression, disordered eating behaviors, and substance abuse). A total of 401 college student participants completed a packet of 18 surveys including 10 surveys used in the present study. Structural equation modeling was used to test each of three hypothesized structural models (Depression, Eating Disturbances, and Substance Abuse). A series of multi-group analyses conducted to test if each of three hypothesized models is invariant across gender indicated no significant difference between females and males. Thus, the data were combined across gender to test for mediated effects in each of three hypothesized models. The results indicated: (a) for the hypothesized model for depression, anxious attachment patterns, avoidant attachment patterns, and negative self-images, but not religious faith, fully mediated the relationship between childhood trauma and symptoms of depression; (b) for the model for eating disturbances, anxious attachment and negative images of self, but not avoidant attachment and religious faith, fully mediated the association between …

The accurate determination of malingering relies on the use of validated and clinically relevant assessment measures. Simulation design is the most often-used research design to accomplish this. However, its external validity is sometimes questioned. The goal of the thesis was to systematically evaluate these major elements: situation, incentives, and coaching. The situation in simulation studies can vary from relevant (academic failure in a college population) to irrelevant (capital murder) for the samples being studied. Incentives refer to the external motivation given to improve simulators' performance and can be positive (extra credit and monetary reward) or negative (extra time and effort). Finally, coaching refers to whether the participant receives any information on detection strategies that are designed to identify feigners. Using a large undergraduate sample in a factorial design, results indicate that a scenario familiar to the participants generally improved the believability of their responses. Coaching also improved the ability to feign convincingly, while incentive type was not associated with any change in scores. The implications of these findings for future research designs and the connection to practice are discussed.

Research indicates that victims of childhood abuse are at increased risk for transmitting violence in adulthood-a phenomenon known as the intergenerational transmission of abuse (ITA). Adult survivors of childhood victimization (i.e., child abuse or witnessed parental violence) are at increased risk for becoming abusive parents, perpetrators of intimate partner violence, and victims of intimate partner violence. The current study examined the latter form of ITA, in which a survivor of childhood victimization is re-victimized in adulthood by intimate partner violence. Attachment theory has been used to explain the ITA by positing that abuse is transmitted across generations via insecure attachment. The purpose of this study was to use structural equation modeling to test the attachment theory of ITA by examining the role of childhood and adult attachment in predicting re-victimization and symptoms of distress in adulthood. In the hypothesized model, childhood victimization by one's parents was hypothesized to predict adult intimate partner violence victimization through insecure attachment relationships in childhood (with one's parents) and adulthood (with one's partner). Furthermore, adult romantic attachment anxiety and attachment avoidance were hypothesized to predict different symptoms of distress. Self-report measures from 59 adult woman seeking services for intimate partner victimization at a domestic violence …
