ADHD Symptomology and Overweight Among College Men (open access)

ADHD Symptomology and Overweight Among College Men

Attention deficit/hyperactivity disorder (ADHD) is a childhood disorder that often persists into adulthood. Among adults, ADHD is highly comorbid with addictive behaviors (e.g., substance abuse and dependence), and depressive disorders. Recently, an association between ADHD and obesity has been reported in the literature; emotional and binge eating may be “addictive behaviors” that contribute to weight gain in this population. The purpose of this study was to test competing models of the hypothesized link between ADHD symptomology and overweight. Specifically, in Model 1, symptoms of depression are expected to mediate the relationship between symptoms of impulsivity and inattention and emotional and binge eating which, in turn, leads to weight gain (i.e., increased BMI). In Model 2, however, the impulsive symptoms have direct relationships with emotional and binge eating in addition to being mediated by depressive symptoms. Structural equation modeling (SEM) was employed to test how the models fit the data of 790 college men. Both models fit the data well, with Model 2 being preferred because of its greater connection to theory. All paths were significant indicating that increased impulsive and inattentive symptoms predicted increased symptoms of depression that, in turn, predicted increased emotional/binge eating, which has a direct and positive …

Effects of Defensiveness on the Reporting of Personality Disorder Symptoms (open access)

Effects of Defensiveness on the Reporting of Personality Disorder Symptoms

Personality disorders are not granted the same clinical attention accorded Axis I disorders despite their instrumental role in treatment and outcome. Even when standardized assessments are used, their clinical utility may be limited by an overly favorable self-presentation. The current study focused on defensiveness, the intentional denial of symptomatology, by examining individuals’ ability to minimize their presentation on personality disorder diagnostic measures. Using a within-subjects simulation design, dually diagnosed inpatients were assessed under both honest and defensive conditions. The study used self-report (Structured Clinical Interview for DSM-IV – Axis II – Personality Questionnaire, SCID-II-PQ) and interview-based (Structured Interview for DSM-IV Personality, SIDP-IV) diagnostic measures and a self-report measure of favorable self-presentation (Paulhus Deception Scales, PDS). The inpatients were quite capable of hiding maladaptive personality traits on diagnostic measures, with similarly large effect sizes on both the SCID-II-PQ and SIDP-IV. In addition to the PDS, two new detection strategies for identifying defensiveness showed promise.

The Effects of Priming, Culture, and Context on Perception of Facial Emotion, Self-representation and Thought: Brazil and the United States (open access)

The Effects of Priming, Culture, and Context on Perception of Facial Emotion, Self-representation and Thought: Brazil and the United States

Individualist and collectivist cultural approaches describe the relationship between an individual and his or her social surroundings. the current study had a two-fold purpose. the first was to investigate whether Brazilians, like other collective peoples, displayed more group self-representations, categorized items more relationally and paid more attention to context than Americans. the second purpose of this study was to investigate if counter-cultural primes played a role in activating either collective or individual selves. Both American (n = 100) and Brazilian (n = 101) participants were assigned either to a no-prime condition or a counter-cultural prime condition and then were asked to rate emotion cartoons, categorize items, complete the Twenty Statement Test (TST), and choose a representative object. As expected, unprimed Brazilian participants displayed more collectivist patterns on emotional (F[1,196] = 10.1, p = .001, ?²= .049; F[1,196] = 7.9, p = .006, ?²= .038; F[1,196] = 9.0, p = .005, ?²= .044) and cognitive (F[1, 196] = 6.0, p < .01, ?² = .03) tasks than Americans. However, Brazilians offered more individualist self-representations (F[1, 195] = 24.0, p < .001, ?² = .11) than American participants. Priming only had a marginal effect on item categorization (F[1,194] = 3.9, p = …

Intuitive Eating Scale: An Examination Among Adolescents (open access)

Intuitive Eating Scale: An Examination Among Adolescents

Intuitive eating assesses the degree to which individuals eat based on physiological cues rather than emotional or situational cues. The Intuitive Eating Scale was initially developed using college women. This study extends the work of Tylka and reports on the psychometric evaluation of the Intuitive Eating Scale (IES) in a sample of 515 middle school boys and girls. Exploratory factor analysis uncovered 4 factors: unconditional permission to eat, eating for physical rather than emotional reasons, trust in internal hunger/satiety cues and awareness of internal hunger/satiety cues; confirmatory factor analysis suggested that this 4-factor model adequately fit the data after 4 items with low factor loadings were deleted. Supporting its construct validity, IES scores were negatively related to body mass index, body dissatisfaction, negative affect, pressure for thinness, and internalization of the thin ideal, and were positively related to satisfaction with life, and experiencing greater positive affect.

Oh G-d, A Borderline: Clinical Diagnostics As Fundamental Attribution Error (open access)

Oh G-d, A Borderline: Clinical Diagnostics As Fundamental Attribution Error

Researchers raise concerns that the diagnostic approach can create stigma and lead to clinical inferences that focus on dispositional characteristics at the expense of situational variables. From social cognitive theory to strict behavioral approaches there is broad agreement that situation is at least as important as disposition. The present study examined the clinical inferences of graduate student clinicians randomly presented a diagnosis (borderline PD) or no diagnosis and either randomly given context information or no context information before watching a videotaped clinical interaction of a fabricated client. Responses to a questionnaire assessing dispositional or situational attributions about the client’s behavior indicated a diagnosis of borderline personality disorder did not significantly increase dispositional attributions and did not significantly moderate the importance of contextual factors. A notable difference between the attributions made by psychodynamic and third wave behavioral respondents was observed. Conceptual and experimental limitations as well as future directions are discussed.

Predicting The Impact Of Abuse: Is Experiential Avoidance A Mediator? (open access)

Predicting The Impact Of Abuse: Is Experiential Avoidance A Mediator?

Intimate partner violence (IPV) occurs between two individuals who have formerly been or are currently in an intimate relationship. IPV includes physical violence, sexual violence, threats of physical or sexual violence, and emotional abuse (Kernic, Wolf, & Holt, 2000; Rennison & Welchans, 2000). Experiencing IPV is associated with a serious impact on psychological health (Afifi, MacMillan, Cox, Asmundson, Stein, & Sareen, 2008; Calvete, Corral , & EstΘvez, 2008). Research on other forms of trauma indicates that experiential avoidance (EA) plays an important role in psychological distress and psychopathology. Thus, it was hypothesized that EA would play a key role in the impact of IPV. Using the Baron and Kenny (1986) method, the current study examined whether EA was a mediator between IPV severity and psychological distress, and whether EA was a mediator between IPV severity and PTSD symptomology, more specifically. In addition, mediational analyses were run to determine if suppression changed the relationships between IPV severity and psychological distress, or IPV severity and PTSD symptomology. Using the same methods, EA and suppression were both also examined as mediators between psychological/verbal abuse severity and psychological distress, and between psychological/verbal abuse severity and PTSD symptomology. No significant results were found in a …

Quantitative EEG Analysis of Patients with Chronic Pain: An Exploratory Study (open access)

Quantitative EEG Analysis of Patients with Chronic Pain: An Exploratory Study

This study examined quantitative EEGs of six individuals with chronic pain and compared them to an age- and gender-matched normative database of healthy control subjects in an attempt to discern whether a particular pattern of resting state EEG activity is associated with chronic pain. In the chronic pain group, significantly reduced absolute power was seen in delta and theta bandwidths at frontal sites in the eyes-closed condition. In the eyes-open condition, significantly reduced absolute power was seen in delta, theta, and alpha bandwidths at frontal, central, and temporal sites, and increased relative high beta power was seen in the parietal region. Reduced theta/high beta and delta/high beta ratios were seen in the parietal region. Quantitative EEG neuromarkers of chronic pain are suggested.

Terror Management Theory and Body Image (open access)

Terror Management Theory and Body Image

Research has not explicitly examined the link between key components of terror management theory (TMT) and body image without the use of mortality salience. This project explored the link between cultural worldview, self-esteem, body image, and death anxiety. Multiple measures were used to create a structural equation model examining relationships between body image and death anxiety as mediated by body image in the context of TMT. The proposed model did not fit the data. Minor modifications were made to the model keeping within the proposed theoretical perspective. In the modified model the relationships between cultural worldview and death anxiety as mediated by body image were either non-existent or weak. Hierarchical regression analyses did suggest that some aspects of body image indeed did predict some, but not all dimension of death anxiety in this sample of young adults.

Validation Of The Facet Satisfaction Scale (Fss): An Evaluative Approach To Assessing Facet Job Satisfaction (open access)

Validation Of The Facet Satisfaction Scale (Fss): An Evaluative Approach To Assessing Facet Job Satisfaction

Job satisfaction has, and continues to be an important construct of interest to researchers and practitioners alike. However, conflicting operational definitions and inconsistent measurement systems have reduced the efficacy of the construct in predicting important job-related outcomes for organizations and their employees. The Facet Satisfaction Scale (FSS) was designed to overcome these deficiencies by creating a facet-based measure that assesses job satisfaction in accordance with recent definitions of the construct. Reliability and validity analyses were conducted on both the complete and shortened version of the scale. The FSS exhibited evidence of reliability (ranging from .52 to .93 for the shortened FSS, and .53 to .96 for the complete FSS). Evidence of scale validity was also obtained through the use of construct, content, and criterion-related validity measures. Implications of the study on future research on job satisfaction are discussed.

Anticipating Work and Family: Experience, Conflict, and Planning in the Transition to Adulthood (open access)

Anticipating Work and Family: Experience, Conflict, and Planning in the Transition to Adulthood

The purpose of this study was to examine the development of work and family plans in young adults, and to clarify the long-term stability, prevalence, and consequences of anticipated work-family conflict. The study utilizes Super’s model of career development and social cognitive career theory, as well as research on current work-family interface, as a framework for understanding the period of anticipating and planning for multiple role integration that occurs between adolescence and adulthood. A sample of 48 male and 52 female college students assessed two years prior completed self-report questionnaires measuring work, marriage, and parenting experience; anticipated work-family conflict; and multiple-role planning. Results of this study suggest that students desire both a career and a family, and recognize potential challenges of a multiple-role lifestyle. Such recognition of anticipated work-family conflict varies by conflict domains and measurement methods, but remains stable over two years. Results also suggest that anticipated work-family conflict does not mediate the relationship between experience and planning; instead, marriage experience predicts planning directly. Implications for the findings are discussed as are suggestions for directions of new research concerning anticipated work-family conflict and planning for multiple roles.

Bipolar Disorder in the Family: Impact on Functioning and Adjustment to College (open access)

Bipolar Disorder in the Family: Impact on Functioning and Adjustment to College

Bipolar disorder is a serious mental disorder, affecting anywhere from 2 to 4 percent of Americans. Though research has indicated that this disorder can be devastating for patients, less is known about how the disorder impacts family members. There is no research that has considered impacts on family members adjusting to college. The purpose of the current study was to determine the extent to which having a family member with bipolar disorder impacts adjustment to college, as well as factors that might account for worse functioning. Two groups were recruited: students with a bipolar family member (n = 25) and students with no family history of the disorder (n = 50). Participants were interviewed regarding their own histories of a mood disorder, as well as mood disorder histories in their immediate families. They then completed surveys assessing adjustment to college, functioning, caregiving burden, parental relationship, and attachment style. Students with a family history of bipolar disorder had significantly lower social adjustment scores, lower personal-emotional adjustment scores, and lower financial functioning scores than students without this history. Lower scores were found even after controlling for psychopathology. Avoidant attachment behaviors, anxious attachment behaviors, and aspects of the paternal relationship were identified as …

Chronic Insomnia and Healthcare Utilization in Young Adults (open access)

Chronic Insomnia and Healthcare Utilization in Young Adults

Chronic insomnia is a highly prevalent disorder in general and young adult populations, and contributes a significant economic burden on society. Previous studies have shown healthcare utilization (HCU) is significantly higher for people with insomnia than people without insomnia. One limitation with previous research is accurate measurement of HCU in people with insomnia is difficult due to a high co-morbidity of medical and mental health problems as well as varying operational definitions of insomnia. Assessing HCU in people with insomnia can be improved by applying research diagnostic criteria (RDC) for insomnia, using a population with low rates of co-morbid medical/mental health problems, and measuring HCU with subjective, objective, and predictive methods. The current study found young adults with chronic insomnia had greater HCU than normal sleepers, specifically on number of medications, and chronic disease score (CDS) estimates of total healthcare costs, outpatient costs, and predicted number of primary care visits. The presence of a medical and/or mental health problem acted as a moderating variable between chronic insomnia and HCU. Simple effects testing found young adults with chronic insomnia and a medical/mental health problem had the greatest HCU followed by normal sleepers with a medical/mental health problem, chronic insomnia, and normal …

Coaches’ Influence on Male Adolescents’ Achievement Motivation, Psychological Factors, and Sport Participation

The motivational climate, as created by coaches, and athletes’ goal orientations are key constructs in understanding children’s experiences with sport. In this study, the relationship between the perceived motivational climates, male adolescents’ goal orientation, and their experiences of self-esteem, sport competence, enjoyment, and ultimately, intention to continue participating in sport was examined. Participants were 405 male adolescents (Sample A: n = 200; Sample B: n = 205) aged 13-15 years old. Structural equation modeling indicated an overall good fit to the structural model for both data sets. A task goal orientation was predicted by higher levels of coach-created task climate. Participants with higher task goal orientation had greater sport competence, self-esteem, and more enjoyment in sport; enjoyment was the only significant predictor of their intention to continue playing the sport they believe is most important over the next three years.

The Development of Disordered Eating Among Female Undergraduates: A Test of Objectification Theory (open access)

The Development of Disordered Eating Among Female Undergraduates: A Test of Objectification Theory

Objectification theory (Fredrickson & Roberts, 1997) has been used to explain how mechanisms related to socialization, sexual objectification, and psychological variables interact to predict mental health difficulties. Among a sample of 626 undergraduate women (age 18-24), this study empirically tested components of Moradi and Huang’s (2008) model and extended it by including additional socialization experiences (i.e., sexual abuse, societal pressures regarding weight and body size). Structural equation modeling analyses suggested that the model provided a good fit to the data and the model was tested in the confirmatory sample. Across the two samples, high levels of Body Shame and low levels of Internal Bodily Awareness directly led and high levels of Societal Pressures Regarding Weight and Body Size, Internalization of Cultural Standards of Beauty, and Self-objectification indirectly led to increased Bulimic Symptomatology and accounted for 65 to 73% of the variance in Bulimic Symptomatology. A history of sexual abuse and sexual objectification were not consistently supported within the model and do not appear to be as salient as the experience of societal pressures regarding weight and body size in understanding women’s experience of bulimic symptomatology. Implications for practice and future research are discussed.

Evaluating Process Variables in Acceptance and Commitment Therapy (open access)

Evaluating Process Variables in Acceptance and Commitment Therapy

Acceptance and commitment therapy (ACT) was developed to specifically target experiential avoidance (EA) rather than any specific diagnostic category. A functional ACT manual was presented and used to treat diagnostically diverse clients in a large sliding fee-for-service training clinic. A multiple baseline across participants and behaviors research design was used to evaluate session-by-session changes in EA, values identification, valued action, and clinical distress. The Acceptance and Action Questionnaire-2 (AAQ2), Valued Living Questionnaire (VLQ), and Outcome Questionnaire (OQ-45) were given to measure processes and outcomes given the functional ACT model presented in the introduction to the paper. Baseline included the Structured Clinical Interview for DSM-IV Axis I and II Disorders given across 2-5 50- minute sessions. The treatment phase consisted of 7-10 50-minute sessions. Participants were 10 clients. Four participants completed sufficient treatment sessions (4-9) to test the study hypotheses. Participants generally improved across time, but most improvements could not be attributed to the functional application of ACT due to changes during baseline for AAQ, VLQ-Consistency, and OQ-45. VLQ-Importance significantly improved for all participants given ACT.

Evaluating the Effectiveness of a Parent training Protocol Based on an Acceptance and Commitment Therapy Philosophy of Parenting

Thirty-four parents were referred by their CPS caseworkers to participate in one of two ACT for Parenting workshops. These workshops followed a 12 hour treatment protocol based on an acceptance and commitment therapy philosophy of parenting. Briefly, an ACT philosophy of parenting maintains that effective parenting requires awareness and acceptance of thoughts and feelings as they occur in the context of the parent-child relationship. An ACT philosophy of parenting also relies heavily on the identification and commitment to parenting values. Participants were asked to track acceptance and valuing behavior on a daily basis for 25 days prior to the intervention and 25 days post-intervention, as well as to complete a package of self-report instruments designed to measure both ACT specific and general psychological processes, at three different points (pre-, post- and follow-up). Nineteen parents received the treatment, and of those, seventeen provided follow-up data 3-4 months post-intervention. Results indicate statistically significant changes in the expected directions for scores on the BASC-2 Externalizing Composite as well as on the Meta-Valuing Measure. A total of 10 parents also evidenced clinically significant change in the expected directions on a variety of outcome measures.

An Examination of Contextual and Process Variables Influencing the Career Development of African-American Male Athletes and Non-Athletes

The purpose of this study was to examine the career development of African-American male athletes and non-athletes. The study utilizes Gottfredson’s circumscription and compromise model of career development as a framework for understanding the way individuals go about selecting different career paths based on various contextual variables and career development processes. A sample of 71 African-American male college students completed self-report questionnaires measuring different aspects of their background make-up, relevant career development processes, and career development outcome variables. Results of the study suggest that non-athlete students have a more developmentally appropriate approach to careers. Results also suggest that perceived career barriers and career locus of control mediate the relationship between athletic status and maturity surrounding careers. Career development is a complicated process and further study on this population is very important, especially when considering athletes. Implications for the findings are discussed as are suggestions for directions of new research concerning African-American career development.

An Examination of Maternal Acceptance among Mothers and their Children with ADHD Symptomatology

The current study examined the role of self-reported and child-reported maternal lack of acceptance in increasing the likelihood of developing internalizing and externalizing symptoms among children with ADHD symptomatology. The effects of a social desirability bias on mother’s self-reports of rejection were controlled for. Mother-child agreement about parenting behaviors like warmth/affection, hostility/aggression and indifference/neglect was also investigated. In addition, variables with the potential to affect agreement (i.e., parents’ social desirability bias, child age, child sex) were examined. Participants included 120 boys and 90 girls, 6 to 11 years old (M = 8.25, SD = 1.18) with and without ADHD and their primary parent/guardian (N = 209). Parent and child participants completed self-report instruments separately. Results indicate that the relationship between mother-and-child-reported ADHD symptoms and internalizing symptoms is strongest when mothers exhibit low levels of rejection. Among the ADHD subsample, maternal lack of acceptance acts as a risk factor by strengthening the relationship between hyperactive/impulsive symptoms and externalizing symptoms. In addition, mothers and their children report significantly different levels of parenting behaviors. Child age and child sex were significant predictors of parent-child disagreement.

An Examination of the Relationship Between Values, Family Environment, and Risk Behaviors Among College Students

The purpose of this study was to examine the roles that values and the family environment play in young adult engagement in risky behavior. One hundred seventy-two male and female college students between the ages of 18-25 completed a demographics questionnaire, the Aspirations Index which measures seven life-goal contents that represent different values, the Cognitive Appraisal of Risky Events that assesses young adults’ perceptions of the risks and benefits associated with involvement in risky activities as well as past involvement in risky behaviors and the Family Environment Scale to assess participants' perceptions of their current family environment. A series of regression analyses were then used to assess the relationship between three dimensions of the family environment and risky behavior involvement and the relationship between participants' intrinsic and extrinsic values and perceived positive consequences and negative consequences of risky behavior. Results from this study supported the idea that certain dimensions of the family environment are related to risk-taking behavior in emerging adults; however, contrary to previous research, the relationship dimension of the family environment was not predictive of young adult risk-taking. Moreover, family activities that communicate family values did not contribute any additional information to the prediction of risk-taking behavior. Findings …

Family Variables in the Cultural and Psychological Adjustment of Third Culture Kids (open access)

Family Variables in the Cultural and Psychological Adjustment of Third Culture Kids

Third culture kids are children raised in globally mobile families who have left their culture of origin to reside in a host culture. As this relocation occurs during childhood, the child combines the values, traditions, and norms of both cultures thereby creating a third culture, a unique culture created by the parent’s integration of the home culture, the host culture, and the domains of the organizational culture. Emotional Stability was found to mediate the relationship between family of origin Expression and Composite distress. Though this was the only hypothesized model that was supported, other interesting findings include that when participants were categorized by industry, statistically significant differences were found between Military, Missions, and the Other group on all of the scales. These differences are likely due to a cohort effect, given that the military family mean age was as much as twenty years higher than the other groups.

Influences on Grief Among Parentally Bereaved Adults

The parent-child relationship is significant throughout the life course, although both positive and negative changes occur as children reach adulthood and develop an identity independent of their family of origin. Grief resulting from parental loss during this time may be a product of many variables including age, relationship quality, and sex roles. The current study examined several variables potentially influencing grief after the death of a parent. As part of a larger study, adults (n = 180) completed measures assessing parental involvement, personal grief and adjustment, as well as sex role preferences. The archival data were subjected to analyses of covariance, taking into account time since the death and children’s sex role preferences (traditional or egalitarian). Female sex of the child was significant in predicting several aspects of grief, suggesting that women have a stronger emotional experience of grief. This may be a result of young women’s stronger emotional bonds with parents when compared to men, feelings of exclusion from college peers during bereavement, or vulnerability for rumination. Sex role preferences were also influential in several aspects of grief. Sex of the parent was not significant, although the interaction for sex of the parent and sex of the child was, …

Intimate Partner Violence Among Female Undergraduates: The Role of Language in the Development of Posttraumatic Stress

Research findings across a variety of samples (e.g., clinical, shelter, hospital) estimate that 31% to 84% of women who have experienced intimate partner violence (IPV) exhibit symptoms of posttraumatic stress disorder (PTSD). The current study sought to further investigate the abuse-trauma link by examining the relationship between lifetime trauma exposure, type of abuse (i.e., physical, psychological), and perspective-taking abilities (i.e., here-there, now-then). The role of experiential avoidance in the development of PTSD symptoms was also examined. Results indicated that lifetime trauma exposure (β = .31) and psychological abuse (β = .34) were significant predictors of PTSD symptomatology. Additionally, analyses revealed that experiential avoidance (β = .65) was a significant predictor of PTSD symptoms that partially mediated the relationship between IPV and PTSD symptomatology. Implications of findings are discussed as well as future suggestions for research examining type of IPV and PTSD.

Is Mind Wandering the Mechanism Responsible for Life Stress Induced Impairments in Working Memory Capacity?

The relationship between life stress and working memory capacity (WMC) has been documented in college students and older adults. It has been proposed that intrusive thoughts about life stress are the mechanism responsible for the impairments seen in WMC. To examine the mechanism responsible for these impairments the current study attempted to induce intrusive thoughts about personal events. The current study allowed for a test of predictions made by two theories of mind wandering regarding the impact of these intrusive thoughts on WMC task performance. One hundred fifty undergraduates were assigned to a control group, positive event group, or negative event group. Participants in the positive and negative event groups completed a short emotional disclosure about an imagined future positive or negative event, respectively, to induce positive or negative intrusive thoughts. WMC measures were completed prior to and following the emotional writing. Results indicated a significant relationship between WMC and mind wandering, however the writing manipulation did not result in any consistent changes in intrusive thoughts or WMC. The results suggest a causal relationship between WMC and mind wandering. The emotional valence of the intrusive thought altered the impact on WMC. No relationship was seen between the measures of stress …

Managing HIV: Self-Efficacy, Mindfulness, Optimism, and Meaning

The purpose of the current study is to investigate the extent to which mindfulness (observing and describing), dispositional optimism and personal meaning are associated with self-efficacy for managing a chronic disease (SEMCD) among 57 people living with HIV in the DFW Metroplex. Several statistical analyses, including a hierarchical linear regression analysis, were conducted. Results indicate, after controlling for age and gender, the overall model accounted for a significant proportion of the variance (adjusted R2 = .39) in self-efficacy for managing chronic disease, F (6, 50) = 5.80, p < .01. Both subscales of mindfulness were significantly related to self-efficacy. However, observing was negatively, associated with SEMCD (β = -0.44, p < .05), and describing was positively associated with self-efficacy (β = 0.60, p < .01). As a result, incorporating these mindfulness skills into self-efficacy based self-management programs may greatly improve self-management, thus positively influencing psychological and physiological health outcomes that are essential to the health and wellbeing of people living with HIV/AIDS. Future research should investigate methods of manipulating observing and describing, and determine what proficiency in these skills is most beneficial to improve self-efficacy.
