Chronically Ill Children: Maternal Stress and Psychological Symptomatology (open access)

Chronically Ill Children: Maternal Stress and Psychological Symptomatology

This study used a parenting stress and coping model to identify predictors of symptomatology for 13 8 mothers of medically compromised children. This model proposed that: child characteristics (severity of the chronic illness and child related parenting stressors); parent characteristics (self-esteem, sense of competence, and parents' perceived stress/distress); and environmental characteristics (social support, general life stressor events, and demographic variables) contribute to psychological symptomatology for these mothers. Multiple regression analysis found a relationship between general life stressor events, severity of the children's chronic conditions, lower satisfaction with social support, lower self-esteem, and younger mothers' ages and greater symptomatology. Trends toward significance were found for more parenting stress and lower parenting sense of competence predicting greater symptomatology. Predicted relationships between family socioeconomic status and parenting daily hassles and symptomatology were not supported.

The Prediction of Adjustment in Institutionalized Juvenile Offenders (open access)

The Prediction of Adjustment in Institutionalized Juvenile Offenders

Predictors of institutional adjustment for juvenile offenders were examined using a sample of 120 males in a detention facility. While demographic information failed to differentiate between well and poorly adjusted juveniles, psychological measures appeared to be more effective. Several MMPI-A clinical scales were useful predictors with the overall elevation in clinical scales being one of the strongest predictors. In addition, the Psychopathy Checklist - Clinical Version (PCL-CV) was a strong predictor of adjustment. Major ethnic differences occurred in the prediction of adjustment, with the MMPI-A and PCL-CV scales predicting infraction rates for the African American group but not Anglo American or Hispanic American groups.

The Relationship Between the Grief Process and the Family System: The Role of Affect, Communication, and Cohesion (open access)

The Relationship Between the Grief Process and the Family System: The Role of Affect, Communication, and Cohesion

Sixty-six people who had recently experienced the death of a parent or a spouse completed a questionnaire packet to assess their current grief symptomatology and some characteristics of the relationships within their family. Participants were asked to fill out a questionnaire 4-5 weeks after the death and then again six months later. The present study compared two competing models to explain whether the grief process affects the characteristics of relationships within the family system or that family characteristics affect the experienced grief symptoms.

Correlates and Predictors of Medication Noncompliance in Patients with Schizophrenia (open access)

Correlates and Predictors of Medication Noncompliance in Patients with Schizophrenia

The treatment of schizophrenia today consists of a multi-component system of services. Mental health professionals generally agree that anti-psychotic medications are an essential treatment for schizophrenia. However, adherence to medication regimens by patients with schizophrenia is notoriously poor. To identify correlates and predictors of medication compliance, the Schedule for Affective Disorders and Schizophrenia (SADS), a semi-structured diagnostic interview, was administered to 90 outpatients with schizophrenia. The results suggest that there are specific variables (i.e., mood symptoms, psychotic symptoms, and socio-demographic variables) that predict medication compliance. In addition, the confirmation of these variables was effective (90.0%) at identifying non-compliant patients. The results suggest that schizophrenia is a complex disorder composed of heterogeneous symptoms. However, a specific group of symptoms is proposed which may provide a screening measure for predicting patients who are likely to be non-compliant with their medications.

Family Rituals and Resilience: Relationship Among Measures of Religiosity, Openness to Experience, and Trait Anxiety (open access)

Family Rituals and Resilience: Relationship Among Measures of Religiosity, Openness to Experience, and Trait Anxiety

Rituals are an integral part of society. The focus of research on rituals has been shifting to highlight the effect rituals may produce on individual resilience and ability to function. This study examined the relationships between participation in family rituals and several conceptually related facets of the human experience, including religiosity, openness to experience, and anxiety. Participants responded to questions on an assessment instrument (Family Ritual Questionnaire) designed to measure participation in a broad variety of identified family rituals; they were grouped according to responses on that questionnaire, and the resulting groups were compared on their responses to questionnaires addressing religiosity (Religious Background and Behavior Questionnaire), openness to experience (Revised NEO Personality Inventory Openness to Experiences scale), and anxiety (State-Trait Anxiety Inventory). The four-group classification system did not produce significant differences on measures of religiosity, openness to experience, or trait anxiety. Nor were there any significant differences noted when the groups were examined on the basis of the demographic characteristics of age, gender, separation time from family of origin, or academic status. The demographic descriptive which was associated with specific group differences related to adult composition of family of origin: participants described the adults present in their families of origin, …

Female Psychopathy Predictors: Cluster B Traits and Alexithymia (open access)

Female Psychopathy Predictors: Cluster B Traits and Alexithymia

Psychopathy has long been lauded as a premier predictor of negative behavioral outcomes because of its demonstrated associations with violence, antisocial conduct, and institutional maladjustment. Traditional conceptualizations of psychopathy highlight the relatively equal importance placed on personality features (i.e., a grandiose, deceitful interpersonal style and deficits in affective experience) and behavioral elements (i.e., an impulsive and irresponsible lifestyle marked by social deviance) of the syndrome. However, little research to date has investigated psychopathy dimensions in female samples, particularly as they relate to maladaptive behaviors beyond forensic settings. The current study comprehensively examined personality (i.e., Axis II Cluster B traits and alexithymia) and behavioral (i.e., suicide-related behavior and aggression) expressions of psychopathy in a sample of female inpatients recruited from trauma and dual-diagnosis units at a psychiatric hospital in Dallas, Texas. Contrary to expectations, the essential components of psychopathy in female psychiatric patients emphasized APD and NPD traits over features of HPD and BPD, which were relatively similar to elements traditionally highlighted in male psychopathy. On this point, two latent dimensions comprehensively addressed female psychopathy in the current sample: impulsive antisociality and narcissistic and histrionic interpersonal style. Interestingly, psychopathy (M r = .01) and Cluster B traits (M r = .05) …

Correlates Between Adult Romantic Attachment Patterns and Dimensional Personality Pathology (open access)

Correlates Between Adult Romantic Attachment Patterns and Dimensional Personality Pathology

Previous research has suggested that adult attachment disturbance is related to maladaptic interaction patterns and personality disorder constructs. Specifically, research indicates that those with attachment disturbance are significantly more likely to meet criteria for a number of personality disorders, including borderline personality disorder, narcissistic personality disorder, and antisocial personality disorder. The purpose of this study was to investigate the associations between adult attachment and the new dimensional model of personality disorders scheduled to be released in the Diagnostic and Statistical Manual for Mental Health Diosrders (5th ed.) in spring 2013. Participants completed the Schedule for Adaptive and Nonadaptive Personality (SNAP) to measure dimensional personality functioning and the Experiences in Close Relationships (ECR-R) and the Attachment Prototypes to measure adult attachment patterns. Additionally, select scales from the Personality Assessment Inventory (PAI) and the Five Factor Model (FFM) will be utilized as secondary measures of personality patterns. The results suggest strong associations between adult attachment orientations and specific maladaptive personality characteristics.

An Examination of Resnick's Model of Malingering: a Pai Study of Feigned Ptsd (open access)

An Examination of Resnick's Model of Malingering: a Pai Study of Feigned Ptsd

Malingered posttraumatic stress disorder (PTSD) poses a formidable clinical challenge in personal injury and disability cases because of the apparent ease in feigning PTSD and the supposed link (proximate cause) to the claimed damages. The effective assessment of feigned PTSD is particularly challenging because this diagnosis is both easier to fake than other Axis I disorders and more difficult to detect. As an additional confound, some patients with genuine PTSD produce highly variable, elevated profiles on multiscale inventories that are difficult to distinguish from feigned PTSD. The current study examined whether the Personality Assessment Inventory (PAI) can effectively differentiate between genuine and feigned PTSD in 109 inpatients from a trauma unit. The two most effective scales were the MAL and the NDS scales. As a primary focus, the current study was the first empirical investigation of Resnick's model of malingered PTSD that is comprised of three subtypes: pure malingering (pure-M), partial malingering (partial-M), and false imputation (false-I). The primary goal was to evaluate whether each feigning group was able to (a) effectively simulate PTSD symptoms and diagnoses and (b) avoid being classified as feigning. The partial-M group proved to be the best feigning group in achieving these two goals. Furthermore, …

Values and Valuing in a College Population (open access)

Values and Valuing in a College Population

Values and valuing behavior have many conceptualizations. Despite how they are defined, values have a significant impact on behavior and are idiosyncratic in nature. The present study reviewed values research and sought to explore values identification and successful valued living among an archived sample of university students. Specifically, in a convenience sample of 282 undergraduate students, variables that affect values identification and behavior such as ethnicity, gender, psychological distress, and psychological flexibility were identified. Results indicated that university students identified with more than one valued living domain (as measured by the PVQ) and that contextual factors such as ethnicity, gender, age, and religiosity/spirituality were associated with specific values endorsed. Furthermore, psychological distress, including depression and anxiety (as measured by the DASS) was negatively correlated with values purity – the extent to which values are freely chosen. Finally, psychological flexibility (low experiential avoidance as measured by the AAQ-2), predicted values purity and successful living in accordance with identified values, and the relationship between these two variables was mediated by psychological flexibility.

Precocious Ego Development in Physically Abused Children (open access)

Precocious Ego Development in Physically Abused Children

The Rorschach records and Wechsler Intelligence Scale scores of sixty-six children between the ages of 5 and 13 were compared. Subjects in each group were from one of three conditions: children who have documented histories of physical abuse, children referred for clinical intervention with no history of abuse, and a community sample of children with no documented history of abuse or psychological treatment. Data from the groups were analyzed to examine evidence of increased reliance on ego functions related to motor activity and concurrent deficits in other areas of ego function by subjects in the physical abuse group. Results revealed that the physical abuse group showed a greater tendency toward color-dominant responses on the Rorschach than the comparison groups and that the Community control group produced records with lower extended form quality than the clinical groups. No significant differences were found for Performance/Verbal IQ split, EB style, Cooperative Movement or Aggressive content.

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits (open access)

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits

Semantic clustering has been used as a measure of learning strategies in a number of clinical populations and has been found to be deficient in individuals with Schizophrenia, but less attention has been paid to the dynamic use of this strategy over the course of fixed-order learning trials. In the current study, we examined this pattern of clustering use over trials in a sample of individuals with Schizophrenia, and explored whether the addition of this dynamic information would help us to better predict specific executive deficits. Results suggested that a decrease in semantic clustering across trials was associated with some executive deficits in the predicted manner. Nonetheless, the overall semantic clustering index generally proved more effective for the purposes, suggesting that in this population, the addition of dynamic information in strategy use is not likely to add considerably to clinical prediction and understanding.

Spirituality, health locus of control, and wellness in organizational health promotion and wellness programs

The relationship between an individual's level of spirituality, health locus of control, and participating in wellness activity was investigated. The relationship between spirituality, health locus of control on physical health was also investigated. The research question was based on prior studies that reported people who are more spiritual are healthier. Does their spirituality lead to increased levels of health, or are individual's who are more spiritual more likely to proactively take control of their health and engage in health promoting behaviors? One hundred and fifteen male and female employees completed The Spiritual Involvement and Beliefs Scale (SIBS), a spirituality measure, The Multidimensional Health Locus of Control Scale, a measure of locus of control related to health and healthcare, and The Center for Disease Control's (CDC) Health Risk Appraisal, a self-report measure of participation in health behaviors. Physical measures of health were obtained by obtaining Body Mass Index, blood pressure readings, and a cholesterol screening. The current study looked at level of spirituality (internal, external), level of health locus of control (internal, powerful other, chance) and participation in wellness/health promoting behaviors and health. Correlational analyses were performed on the relationship between spirituality and health locus of control. Hierarchical multiple regressions were …

Sexual orientation self-label, behavior, and preference: College students in Taiwan and the USA

The relationships among self-labeled sexual orientation, sexual preferences, and sexual behaviors were examined in samples from Taiwan and the USA. Subsamples matched on gender, age, and marital status were created to reduce sexual orientation cell size discrepancies and demographic differences. Sexual orientation self-label, the Kinsey Scale of Sexual Orientation, and a modified version for preference were used to assess participants' sexual orientation, behavior, and preference, respectively. Additional measures included an adaptation of the Early Sexual Experiences Checklist, and the Hopkins Symptom Checklist for psychological distress. For both Taiwan and USA subsamples, heterosexual participants reported significantly greater congruence between sexual orientation identity and preference than did nonheterosexual participants. A high proportion of the Taiwan sample were celibate, precluding analyses of congruence between sexual orientation identity and sexual behavior. Congruence between sexual behavior and preference in the USA sample was negatively correlated with psychological distress. In a cross-cultural comparison between the Taiwan and USA women (n = 176), the two samples reported similar congruence between sexual orientation identity and preference. Exploratory analyses revealed that heterosexual participants' sexual orientation label was more “public, ” (more categories of people who knew the participants' sexual orientation), than was nonheterosexuals' in both Taiwan and the USA. …

Developmental Stressors and Associated Coping Skills in the Development of Disordered Eating in College Females

Access: Use of this item is restricted to the UNT Community
There is a lack of clarity in the current literature in how potential etiological factors interact and result in disordered eating. The purpose of this study was to examine an expanded model of Personality, Social Support, Appraisal/Coping Processes, Abuse History, Internalization of Sociocultural Standards, Psychological Disturbances, and Body Disparagement in the development of disordered eating. The current model was evaluated using 276 women in their transition to college, a time period highly associated with symptoms believed to increase a woman's risk for the development of disordered eating including perceived difficulty coping, weight gain, and negative affect. Structural equation modeling was used to allow simultaneous examination of the causal relationships between the factors. Structural analyses confirmed that college women with previous stressful experiences appraised the adjustment to college as more stressful and reported feeling less able to cope with the transition. Those women who identified the transition as overwhelming were also aware of increased negative mood and psychological states since beginning the school semester. Further, women with previous traumatic sexual experiences appeared to be at additional risk for increased negative affective symptoms. The resulting model confirmed that those women who experience negative mood states and those that endorse strong internalization of …

Is Mattering what Matters: A Validation Study of the Meta-Valuing Measure of Flexible Valuing

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.

Organized Semantic Fluency and Executive Functioning in an Adult Clinical Sample and a Community Sample

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.

Factors Affecting Revictimization in Survivors of Childhood Sexual Abuse (open access)

Factors Affecting Revictimization in Survivors of Childhood Sexual Abuse

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 …

First Impressions of Therapists: the Effect of Therapist Gender, Gaze, Smiling and Subject Gender

Conceptualization psychotherapy as an interpersonal influence process emphasizes how a therapist is perceived by a client. Factors affecting a client's early impressions of a therapist could influence therapeutic interactions since first impressions are relatively stable. The study investigated effects of nonverbal behavior and gender during a simulated initial meeting between a therapist and client. Undergraduates (N = 466) viewed a male or female therapist interviewing with a new female client. Therapist gaze .(100%, 80%, 40%) and smiling (high, low) were manipulated. After subjects viewed one of 12 videotapes, they completed questionnaires rating therapist expertness, trustworthiness, attractiveness, masculinity and femininity. A comparison of the therapist with subjects' expectations of a therapist in general was obtained by pre- and post-testing utilizing a measure of client expectations. MANOVAs were performed on all ratings except expectation scores, where an ANCOVA was utilized. Main effects for therapist gender indicated the female therapist was rated as significantly more expert, attractive, trustworthy and feminine than the male (ps < .81). For ratings of masculinity, subject gender interacted with therapist gender (p < .001). Wain effects showed that high smiling was rated as more attractive and more feminine (ps < .01).

Relationships of Sex-Role Identification, Self-Esteem and Attitudes Toward Women to Responses on a Scale of Sexist Humor

Theories and research in the field of disparaging humor were reviewed, and sexist humor was studied as representative of this field. The relationships of sex-role identification, self-esteem, and attitudes toward women to the judgement of humor in sexist material were investigated. The Scale of Sexist Humor, developed for this investigation, utilized a set of 50 cartoons and jokes devised to approximate overlapping standard curves on the dimensions of sexist content and humor. Subjects were 57 males and 70 female undergraduate students. Each subject performed a forced Q^-sort of the cartoons and jokes, thereby rating them on a five-point scale of funniness, then completed instruments designed to evaluate sex-role identification (the Personal Attributes Questionnaire), self-esteem (The Texas Social Behavior Inventory), and attitudes toward women (the Attitudes Toward Women Scale), A demographic information sheet was also obtained from each subject to utilize in ancillary analysis.

Imaginative Involvement and Hypnotic Susceptibility (open access)

Imaginative Involvement and Hypnotic Susceptibility

J. Hilgard (1970, 1972, 1974, 1979), utilizing an interview format, asserted that a personality variable, namely, an individual's capacity to become imaginatively involved in experiences outside of hypnosis, was significantly correlated with his or her hypnotic susceptibility. Tellegen and Atkinson (1974) operationalized the imaginative involvement variable in a 37-item questionnaire, the Tellegen Absorption Scale (TAS) that correlated significantly with hypnotic susceptibility (e.g., Crawford, 1982). However, Council, Kirsch, and Hafner (1986) suggested that the relationship between the TAS and hypnotic susceptibility is a context-mediated artifact in that the two correlate only when the TAS is administered within a context clearly identified as involving hypnosis. As the interviews conducted by J. Hilgard (1970, 1972, 1974, 1979) were done within a context clearly identified as involving hypnosis, the possibility exists that the relationship between imaginative involvement and hypnotic susceptibility is also a context-mediated artifact. In a test of this possibility, 86 subjects were interviewed concerning their imaginative involvements. Forty-three subjects were interviewed within a context defined as "research investigating hypnosis" and 43 subjects were interviewed within a context defined as "research investigating imagination." Hypnotic susceptibility was assessed in sessions separate from the interviews. In the present study, an individual's hypnotic susceptibility was not …

Computer Games: Psychomotor Sequelae and Personological Covariates

This study investigated the relationship between the degree of involvement with video games of 72 male university students with performance on pilot screening tests of psychomotor abilities, perceptual abilities, and cognitive style, and also with several personological variables, school performance, locus of control, sociability, and social presence. Additionally, the effects of experience with a video game on the learning of perceptual and psychomotor skills was examined for different levels of previous computer game involvement. It was found that those students who began playing at earlier ages and who more recently played the most demonstrated increased psychomotor abilities, and those abilities appeared to be enhanced by video game play. Greater amounts of time per week spent with computer games were found to correlate with increased facility in learning perceptual skills on computerized instrumentation, and with relative underachievement in school. No systematic relationship was found between degree of video game involvement and measures of sociability, social presence, and field dependence-independence. The study concluded that computer games may have effects upon those individuals who play them, but the effects may not be as negative as many people believe.

Genotypic Handedness, Memory, and Cerebral Lateralization

The relationship of current manual preference (phenotypic handedness) and family history of handedness (genotypic handedness) to memory for imageable stimuli was studied. The purpose of the study was to test the hypothesis that genotypic handedness was related to lessened cerebral lateralization of Paivio's (1969) dual memory systems. The structure of memory was not at issue, but the mediation of storage and retrieval in memory has been explained with reference to verbal or imaginal processes. Verbal mediation theories and supporting data were reviewed along with imaginal theories and supporting data for these latter theories. Paivio's (1969) dual coding and processing theory was considered a conceptual bridge between the competing positions.

Judgment of Contingency and the Cognitive Functioning of Clinical Depressives

Twenty-four psychiatric staff, 24 clinically depressed inpatients, and 24 nondepresssed schizophrenic patients at a state psychiatric facility completed five tasks under either reward or punishment conditions. Each task consisted of 30 trials of pressing or not pressing a button to make a light appear. Monetary reinforcement was contingent on light onset for the final ten trials of each task. Cash incentives for judgment of control accuracy were added for Tasks 3, 4, and 5. Cognitive functioning was evaluated on each task by measuring expectancy, judgment of control, evaluation of performance, and attribution. Mood and self- esteem were measured before and after the procedure. No significant differences were observed across mood groups for expectancy of control or judgment of control accuracy. Subject groups also did not differ in the attributions they made or in how successful they judged their performances to be. They set realistic, attainable criteria for success which were consistent with relevant conditional probabilities. Subjects in reward gave themselves more credit for task performance than subjects in punishment gave themselves blame for comparable performances. Punishment subjects demonstrated more stable, external attributions than those in reward. Across tasks, subjects overestimated when actual control was low and underestimated when actual control …
