Fatigue and Inhibitory Control: A Test of Key Implications of an Emerging Analysis of Behavioral Restraint Intensity (open access)

Fatigue and Inhibitory Control: A Test of Key Implications of an Emerging Analysis of Behavioral Restraint Intensity

Agtarap, Wright, Mlynski, Hammad, and Blackledge took an initial step in providing support for the predictive validity of a new conceptual analysis concerned with behavioral restraint - defined as active resistance against a behavioral impulse or urge. The current study was designed to partially replicate and extend findings from their study, employing a common film clip protocol and a procedure for inducing low- and high levels of fatigue. Analyses indicated that key cardiovascular (CV) responses rose with the evocativeness of the film clip among low fatigue participants but fell with the evocativeness of the film clip among high fatigue participants. This is consistent with the prediction that high fatigue participants would put forth more restrain intensity than low fatigue participants when confronted with the less evocative clip, but less restraint intensity than low fatigue participants when confronted with the more evocative clip. Behavioral restraint performance - quantified as duration of facial non-neutrality - was also consistent with predictions, being impaired by fatigue under high- but not low evocativeness conditions. Findings support the broad theoretical suggestion that fatigue influence on behavioral restraint is multifaceted, dependent on the perceived magnitude of the impulse or urge experienced and the importance of resisting it.

Depression, Religious Behaviors and Social Support as Predictors of Health-Related Quality of Life among HIV Positive Individuals

Access: Use of this item is restricted to the UNT Community
The goal of the current study was to evaluate the ways in which religious behaviors and perceived social support are associated with the relationship between depressive symptoms and health-related quality of life for this group. We hypothesized (1) that religious behaviors moderate the relationship between depressive symptoms and health-related quality of life, (2) perceived social support mediates the relationship between depressive symptoms and health-related quality of life and (3) that religious behaviors moderate the mediational indirect effect of perceived social support in the depression and health-related quality of life relationship. Findings from a sample of 244 HIV-positive individuals provided evidence to support direct, conditional, and indirect effects on the depressive symptoms and health-related quality of life relationship. A discussion of the findings, implications for future research and clinical practice are provided.

Survey of Psychology Professionals on Their Involvement in Sport and Performance Psychology Services (open access)

Survey of Psychology Professionals on Their Involvement in Sport and Performance Psychology Services

This study examined professional practice issues in sport psychology such as qualifications, credentialing, graduate training, and the scope of practice in order to address questions about who should be teaching and providing such services. We used frequencies, t-tests, and chi-square analyses to assess trends among licensed psychologists in the subdiscipline of sport psychology. Analyses show that 26.7% (n = 52) reported providing services to individual athletes and 17.9% (n = 35) to teams in which their work focused on directly improving sport performances. Additionally, 58.5% (n = 114) reported providing mental health services to individual athletes and 10.3% (n = 20) to sport teams. These results suggest services provided to individual athletes and groups/teams of athletes seem to emphasize mental health concerns. Regarding supervision, 18.5% (n = 36) indicated they had received supervision related to improving athletes' sport performance and 35.9% (n = 70) for mental health services they had provided. Another 17.5% (n = 34) indicated having provided supervision to other professionals who were working with athletes to improve their sport performance and 40.0% (n = 78) for those who were addressing athletes' mental health. Overall, 26 (13.3%) of the psychologists had published articles concerning sport and performance psychology …

Examining the Relationship between Bullying Experiences, Parental Partner Violence, and Partner Violence in Young Adulthood (open access)

Examining the Relationship between Bullying Experiences, Parental Partner Violence, and Partner Violence in Young Adulthood

The current study used secondary analysis of existing data to examine associations between bullying experiences, parental partner violence, and partner violence in young adulthood. We hypothesized that bullying in adolescence would be associated with witnessing parental IPV in adolescence and IPV in young adulthood. We believed that deficits in social information processing, particularly hostile attribution biases, would be associated with adolescent bullying. Lastly, we believed that decentering would act as a moderator, affecting the relationship between adolescent bullying and IPV in adulthood. We used correlational and moderation analyses to examine these hypotheses and found that relational bullying victimization was associated with witnessing parental IPV, and the frequency of bullying perpetration was associated with IPV perpetration in adulthood. We found that some aspects of bullying victimization were negatively associated with being unassertive, bullying perpetration was associated with hostile attribution biases, and the relationship between bullying and IPV was significant only at certain levels of decentering maturity.

Finding a Data-Driven Definition of Binge-Watching (open access)

Finding a Data-Driven Definition of Binge-Watching

Binge-watching, the act of watching large amounts of television at a time, has become a popular phenomenon internationally; however, it has yet to be sufficiently defined. In order to define binge-watching, data was collected on specific watching instances from 216 undergraduate students at a large research university. Hierarchical and k-means cluster analyses were conducted in Phase I to empirically determine how binge-watching should be defined. In Phase II, that definition was tested by correlating the number of instances of binge-watching in a one-week period, collected by seven days of daily diary logs, with several theoretically related measures including body mass index, dissociative tendencies, psychological distress, compulsion to watch, boredom proneness, and escapism through watching. The data-driven definition was found to be that eight hours or more of continuous watching was binge-watching, while anything less than that was not. In Phase II, the frequency of binge-watching through the seven-day period was calculated based on that new definition. The frequency of binge-watching was positively correlated with body mass index and dissociative tendencies with statistical significance at the alpha = .05 level. Compulsion to watch was not statistically significant; however, there was a positive correlation. These findings indicate that the proposed data-driven definition …

Exploring Predictors of Self-Forgiveness (open access)

Exploring Predictors of Self-Forgiveness

Self-forgiveness is a growing sub-field of the broader study of forgiveness, and initial research has linked self-forgiveness to positive mental and physical health outcomes. However, the extant literature on self-forgiveness is in its infancy, and there is a need for further research to understand the predictors of self-forgiveness and the clinical implications that might follow. The current study aimed to build on the extant literature by exploring two sets of predictors of self-forgiveness: (1) the four Rs as proposed in Cornish and Wade's four-R therapeutic model of self-forgiveness (i.e., responsibility, remorse, restoration, and renewal) and (2) personality as measured by the Big Five. This study also explored how responsibility for the offense and humility might moderate the relationship between self-forgiveness and well-being. Participants were undergraduates recruited from a large, public university in the southwestern United States. They were instructed to describe a recent interpersonal offense they had committed and complete a questionnaire. The overall results suggest that there is a negative cross-sectional relationship between responsibility, remorse, and restoration with self-forgiveness and that, when taken together, the four-Rs account for a significant amount of variance in self-forgiveness. Neuroticism was negatively associated with self-forgiveness while conscientiousness and extraversion were positively associated with …

An Alternative Operationalization of Betrayal Trauma using Perceived Betrayal (open access)

An Alternative Operationalization of Betrayal Trauma using Perceived Betrayal

There are many identified factors that correlate with whether an individual experiences adverse symptoms following a traumatic event. Research indicates that betrayal, where the victim is betrayed by another individual, may be one of these factors. Betrayal Trauma Theory (BTT) posits that betrayal during trauma increases the likelihood of developing adverse psychological symptoms. BTT objectively dichotomizes traumas as high betrayal or low betrayal traumas based on details of the event. Though literature finds those who experience high betrayals experience more severe symptoms of PTSD, depression, anxiety, and dissociation than those who experience low betrayals, this objective classification is limited as it is based solely on the circumstances of the trauma and does not give the victim the option of indicating whether they felt betrayed. We believe perceptions of betrayal, whether the event meets the objective criteria of betrayal put forth by BTT or not, is an important predictor of trauma-related outcomes. This study (N = 244) found that perceived betrayal predicts symptoms of PTSD and depression independently, as well as when controlling for objective betrayal, dependence on the perpetrator, event centrality, anxiety, and dissociation. These findings indicate perceived betrayal is a unique construct that should be included in the operationalization …

Determining the Diagnostic Accuracy of and Interpretation Guidelines for the Complex Trauma Inventory (CTI) (open access)

Determining the Diagnostic Accuracy of and Interpretation Guidelines for the Complex Trauma Inventory (CTI)

The work group in charge of editing the trauma disorders in the upcoming edition of the International Classification of Diseases (ICD-11) made several changes to the trauma criteria. Specifically, they simplified the criteria for posttraumatic stress disorder (PTSD) and added a new trauma disorder called complex PTSD (CPTSD). To assess the new and newly defined trauma disorders, Litvin, Kaminski and Riggs developed a self-report trauma measure called the Complex Trauma Inventory (CTI). Although the reliability and validity of the CTI has been supported, no empirically-derived cutoff scores exist. We determined the optimal CTI cutoff scores using receiver operating characteristic (ROC) analyses in a diverse sample of 82 participants who experienced trauma and were recruited from an inpatient trauma unit, student veteran organizations, and university classrooms. We used the Clinician-Administered Interview for Trauma Disorders (CAIT) to diagnose the presence of an ICD-11 trauma disorder, and we correlated the results of the CAIT with the Clinician-Administered PTSD Scale for the DSM-5 to establish the convergent validity of the CAIT, r = .945, p < .001. For the ROC analyses, the CTI was used as the index test and the CAIT was used as the criterion test. The area under the curve (AUC) …

Exploring Psychosocial Correlates of Disordered Eating among Male Collegiate Athletes (open access)

Exploring Psychosocial Correlates of Disordered Eating among Male Collegiate Athletes

In research on disordered eating in female collegiate athletes, psychosocial correlates including elevated scores on measures of body image concerns, weight pressures, sociocultural internalization, and mood state were found significantly more often in either the eating disorder or symptomatic group as opposed to the asymptomatic group. Unique or nuanced pressures exist for male athletes as well, specifically a different ideal for body image, often described by a drive for muscularity. I examined these effects in a sample of 698 male collegiate athletes. All participants completed questionnaires, which provided measures of drive for muscularity, social desirability, body satisfaction, negative affect, sociocultural pressures, sport weight pressures, and internalization and social comparison among other factors not pertinent for this analysis as part of a larger study. Exploratory factor analysis confirmed the existence of five factors (general and sport pressures, internalization, body dissatisfaction, negative affect and drive for muscularity) to which a sixth was added to reflect dietary intent, all of which are explained in the Petrie and Greenleaf sociocultural model. A logistic regression showed that dietary intent and drive for muscularity differentiated significantly between the symptomatic/eating disordered athletes and those who were asymptomatic.

Political Humility: Engaging Others with Different Political Perspectives (open access)

Political Humility: Engaging Others with Different Political Perspectives

The purpose of this study was to explore theorized predictors, intrapersonal effects, and interpersonal effects of political humility. Participants (N = 469) were adults recruited from Amazon's Mechanical Turk and undergraduate students who completed a series of measures online. First, I found that political humility is (a) positively associated with openness to experience, (b) negatively associated with political commitment, and (c) not significantly related to political diversity in one's social network. Second, regarding intrapersonal effects, I found that political humility was (a) positively associated with low emotional reactivity when presented with a different political perspective, (b) identifying positive aspects of the opposite political perspective, and (c) not significantly related to identifying negative aspects of one's own political perspective. Third, I found that both the self-reported political humility of the participant and the perceived political humility of the individual who hurt or offended the participant were positively associated with one's motivation to forgive the individual. Fourth, I found that the association between political humility and forgiveness was not significantly moderated by how close the participant felt to the offender before the hurt or offense. I conclude by discussing my findings in light of the present literature on humility.

Differences in Coping Strategies and Multifaceted Psychological Outcomes among Trauma Survivors (open access)

Differences in Coping Strategies and Multifaceted Psychological Outcomes among Trauma Survivors

The World Health Organization has proposed for the ICD-11 a differentiation of symptoms to distinguish separate disorders of PTSD and complex PTSD (CPTSD), rather than one disorder of PTSD as in the current DSM-5. In addition, the accuracy and usefulness of the borderline personality disorder (BPD) diagnosis has been debated for years due to this history of trauma often associated with the diagnosis. New instruments have been developed to assess CPTSD, allowing needed research to expand our understanding of CPTSD and how it may differ from PTSD. The present study explored the relationships between the three different patterns of symptom expression associated with these disorders and various coping strategies in a sample of trauma survivors. A canonical correlation analysis (CCA) showed a significant relationship between trauma symptoms and coping strategies and suggested that individuals with higher borderline personality disorder symptoms, and subsequently complex PTSD and PTSD symptoms, were more likely to cope using avoidant coping strategies- behavioral disengagement, denial, and substance use. This finding was similar to previous research findings that suggested high rates of negative psychological outcomes for adults cognitive and behavioral avoidant coping strategies. Contributions from other coping techniques, such as restraint and venting, also showed significant, but …

Prolonged Grief and Couple Functioning: The Role of Religious Coping and Social Support (open access)

Prolonged Grief and Couple Functioning: The Role of Religious Coping and Social Support

Our sample consisted of 116 adults aged 18 and older, recruited from college and community settings. Participants were currently in a romantic relationship and endorsed the sudden and/or violent death of a family member, close friend, or romantic partner. We hypothesized that: 1) prolonged grief is associated with poor dyadic functioning; 2) social support moderates the relationship between prolonged grief and dyadic functioning; 3) religious coping moderates the association between prolonged grief and dyadic functioning. Results indicated that prolonged grief was not significantly related to dyadic functioning, and neither social support nor religious coping moderated this association.

Bipolar Spectrum Traits in Day-to-Day Life: Ecological Momentary Assessment of Reward Sensitivity, Circadian Timing, and Experience of Reward in the Environment

Access: Use of this item is restricted to the UNT Community
The current study examined 236 undergraduate students in a week long twice-per-day ecological momentary assessment exploring the influence of baseline reward sensitivity and interactions between circadian variables (i.e., total sleep time, sleep quality) and daily measures of reward. Though primary study findings did not support reward sensitivity related moderation of sleep-reward pathways, a number of notable findings emerged. We found evidence of specific domains of reward sensitivity (anticipatory reward and reward responsiveness) which are uniquely related to daily experiences of reward. In addition, bidirectional circadian-reward pathways were found between sleep quality and daily rewards which suggests pathways towards reward-related engagement. Evidence also supported interactions between sleep quality and total sleep time on experience of daily reward, further highlighting the complexity of sleep-reward pathways and their relevance to mood symptoms.

Comparing Cognitive Functioning in White Mexican/Mexican Americans and non-Hispanic White Americans with and without Type 2 Diabetes

Access: Use of this item is restricted to the UNT Community
To better understand the impact of type 2 diabetes, the relationship between ethnicity, specifically Mexican/Mexican American ethnicity, and the disease must be further investigated. This study specifically examined the cognitive impact of type 2 diabetes. Data from the 2014 Health and Retirement Study was used to compare the cognitive functioning of non-Hispanic White (n = 10,658) and White Mexican/Mexican American (n = 847) individuals, age 50+ years, with and without type 2 diabetes. Serial 7's and immediate and delayed recall—hypothesized to be more negatively affected by type 2 diabetes and Mexican American status—was compared controlling for age, education, and depression. A multivariate analysis of covariance (MANCOVA) indicated significant main effects for race/ethnicity (F(3,11496) = 11.15, p < .001) and diabetes status (F(3,11496) = 3.15, p < .024), with Mexican Americans and those with diabetes having worse cognitive performance. There were significant effects for all covariates. A step-wise multiple regression indicated that education, age, depression, race/ethnicity and diabetes status accounted for a combined 28.4% of variance in a cognitive performance composite. Implications for assessment and treatment are discussed.

An Examination of Risk and Resilience Factors Predicting Executive Functioning in Women following Psychological Trauma (open access)

An Examination of Risk and Resilience Factors Predicting Executive Functioning in Women following Psychological Trauma

Psychological trauma may affect higher-order executive functions, which include selective attention, inhibition, and task-switching processes. Difficulty in these executive processes can in turn influence individuals' daily functioning and may also negatively affect the psychological treatment of post-trauma symptoms. Women may be most at risk for developing problems with executive functioning following trauma, consistent with their overall greater risk of developing post-trauma symptoms. Yet, little is understood about the influence of psychological variables, premorbid functioning, and specific trauma factors in determining post-trauma cognitive functioning in women. Additionally, individual variability in susceptibility to psychological distress and neuropsychological deficits following trauma remains an open area of study. The present study investigated the relationship between psychological and trauma factors with neuropsychological outcomes in women with trauma histories as well as individual variability in risk for poor neuropsychological outcomes. In total, 60 participants' data (age M = 29.73, SD = 10.91) were included in analyses. The final sample consisted of 33 community members recruited from the UNT Psychology Clinic and the UNT student body and 27 veterans recruited from the Veterans Affairs North Texas Healthcare System (VANTHCS). Regression and path analysis identified premorbid intellectual functioning as a predictor of better neuropsychological outcomes and anxiety and …

Are You a Good Witch or a Bad Witch? The Importance of Object Relations in Modern Assessment (open access)

Are You a Good Witch or a Bad Witch? The Importance of Object Relations in Modern Assessment

The Social Cognition and Object Relations Scale—Global (SCORS-G) is a relatively new scoring system for the Thematic Apperception Test (TAT) that provides information about an individual's functioning in a variety of domains, including intrapsychic and interpersonal. Participants in this archival study had been administered a variety of measures as part of a routine clinical assessment, including the TAT, Rorschach, Minnesota Multiphasic Personality Inventory-2, and the Wechsler Adult Intelligence Scale. Selected TAT stories were rescored using current SCORS-G scoring criteria. This dissertation evaluated the factor structure of the SCORS-G in an outpatient sample with a principal component analysis (PCA), finding support for a two-component solution. The SCORS-G was then compared to well-established measures of personality functioning, social cognition, and object relations using correlational analyses, with mixed results. Lastly, support was found for using the SCORS-G as a tool for discriminating individuals with a history of violent or problematic relationships from those without such a history. Implications for card selection based on card pull and the impact of bland protocols were explored.

Self-Efficacy and Competence: A Physical Activity Experimental Comparison (open access)

Self-Efficacy and Competence: A Physical Activity Experimental Comparison

Sedentary behavior has been shown to lead to overweight and obesity, which are risk factors for chronic diseases such as cardiovascular heart diseases (CHD) and type 2 diabetes mellitus. Two constructs have been used to attempt to enhance motivation in order to promote long-term physical activity behavior change: self-efficacy (from Self-Efficacy Theory) and competence (from Self-Determination Theory). Though these constructs are from two different theories and purportedly measure two different concepts, they have been used interchangeably in physical activity research. This project examined similarities and differences in the theoretical explanations of self-efficacy and competence. Participants were college students ages 18 to 53 (n = 194, 65.8% female) who were randomized to one of two intervention groups (competence vs. self-efficacy) or an attention control group, with an overall attrition rate of 0.6%. Repeated measures ANCOVAs controlling for strenuous exercise and BMI showed no within groups or between-groups differences in competence or self-efficacy. Measures of competence and self-efficacy were strongly correlated (r = .74). Further inspection showed both measures were tapping into a third variable: confidence. Additionally complicating the findings is documented evidence of college students over-reporting high confidence levels. Recommendations include incorporating items measuring growing mastery into competence scales and examining …

The Effects of Suggestibility, Compliance, and Situational Stress on Miranda Abilities, Waiver Decisions, and False Confessions (open access)

The Effects of Suggestibility, Compliance, and Situational Stress on Miranda Abilities, Waiver Decisions, and False Confessions

Miranda abilities, individual characteristics, and contextual factors are critical elements to evaluate in determining the validity of Miranda rights waivers and confessions. Research indicates that many individuals waive their Miranda rights without adequate comprehension or reasoning. In addition, personality characteristics of suggestibility and compliance are key factors influencing waiver decisions. Furthermore, scholars found that situational anxiety likewise impairs Miranda abilities and waiver decisions. Previous research has investigated the effects of Miranda abilities, individual characteristics, and contextual factors on Miranda waivers and confessions by utilizing confession paradigms. A methodological limitation of these paradigms is the lack of volition and autonomy in committing the accused acts of wrongdoings. The current study of undergraduate students advances previous research through examining the detrimental impact of false accusations of wrongdoings committed independently and intentionally using a novel paradigm. This thesis sought to further the understanding of the effects of Miranda abilities (i.e., comprehension and reasoning), personality characteristics (i.e., suggestibility and compliance), and situational factors (i.e., false accusation) in relation to Miranda waivers and confession decisions. The final sample included 87 undergraduate students, of whom approximately 97% waived their rights and 40% falsely confessed to the wrongdoing. The results indicate that Miranda reasoning, suggestibility, and compliance …

Universal Suicide Risk Screening in the Parkland Health and Hospital System: Evaluation of the Parkland Algorithm for Suicide Screening

Access: Use of this item is restricted to the UNT Community
Suicide is a significant public health issue in the US. Despite national and international prioritization since 1996, little definitive progress has been made in terms of identification and intervention in cases of elevated suicide risk. Forty percent of those who died by suicide attended an emergency department within a year of death. Therefore, universal suicide risk screening in emergency departments could prove a vital component to a national suicide prevention strategy. The present study empirically evaluated the universal suicide risk screening program recently implemented at Parkland Health and Hospital System. The sample consisted of patients over 18 years of age (N=333,855; Mage=42.7, 32% male) screened as part of routine clinical care from May 4th, 2015, through November 3rd, 2015. The Parkland Algorithm for Suicide Screening (PASS) is part of a clinical decision support system for responses to Columbia - Suicide Severity Rating Scale Clinical Practice Screener (C-SSRS) items, leading to an automated clinical response via three suicide risk stratification levels: no action for no risk identified, psychiatric social worker assessment for moderate risk identified, and psychiatrist/psychologist interview for high risk identified. The present study used receiver operating characteristic (ROC) curve analysis, which found the PASS predicted disposition (z=30.46, p<.001, AUC=.78, …

Therapeutic Assessment as Preparation for Psychotherapy (open access)

Therapeutic Assessment as Preparation for Psychotherapy

This study examined the impact therapeutic assessment (TA) had on participants recruited from the UNT Psychology Clinic's waiting list. Using a pretest-posttest design, participants completed measures prior to and following their assessment. UNT Psychology Clinic archive data was used to compare this sample to clients who received traditional information gathering assessments with implicit measures, those receiving assessments relying on only self-report measures, and those who did not receive an assessment before beginning psychotherapy. The findings of this study vary based on the criteria being examined. Due to the small sample in the experimental group, no statistical significance was found through null hypothesis testing. However, the TA group's scores on the Outcome Questionnaire – 45 (OQ) and the Working Alliance Inventory (WAI) indicated better outcomes than those without a TA, with large effect sizes. Furthermore, those who received a TA were more likely than those without a TA to score below the clinically significant cutoff levels on the OQ. The study raises issues for consideration in what is deemed "effective" in therapeutic efficacy research.

Healthy Eating in College Students: 24-Hour Dietary Recall and the Theory of Planned Behavior (open access)

Healthy Eating in College Students: 24-Hour Dietary Recall and the Theory of Planned Behavior

The transition to college is marked by poorer eating behaviors. The Theory of planned behavior (TPB) represents a promising tool for predicting eating behaviors through the examination of attitudes (ATT), subjective norms (SN), perceived behavioral control (PBC), and intention (INT). Despite prior application of the TPB, there exist several key methodological issues in the literature addressing eating behaviors. The present study utilized an enhanced dietary assessment methodology, the ASA24 dietary recall, and a short-term prospective design to assess the healthy eating behaviors of emerging adults in college. Dietary recalls of 68 participants (average age = 20.76 years; 70.6% female; 70.6% non-Hispanic, 48.5% White, 22.10% Black/African American, 13.20% Asian) were analyzed using the Healthy Eating Index (HEI)-2010 scoring system. Results revealed that very few college students are meeting recommended dietary guidelines. Linear regression indicated that the indirect TPB variables (ATT, SN, and PBC) were related to INT (F[3,64] = 19.67, p < .001), although SN did not account for unique variance. Further, the direct TPB variables (INT and PBC) were related to HEI-2010 scores (F[2,65] = 4.00, p = .023); however, only PBC accounted for significant variance. Overall, findings suggest that more favorable attitudes relate to intention, but only perceived behavioral …

Adult Attachment, Cultural Orientation and Sacrifice in Couples: A Comparison between American and Chinese Samples

The present study examined the effects of adult attachment and cultural orientation on sacrifice behaviors and the corresponding emotional reactions, using a cross-cultural sample in the U.S. and China. Strain-tests protocol was utilized in this study, in which an individual (i.e., the asker) was asked to share with their romantic partner a personal goal that required a major sacrifice from their partner (i.e., the responder), and then entered a discussion to process their plan of carrying out this goal. The final sample included 115 couples from the U.S. and 99 couples from China. Results indicated that responder's attachment avoidance was negatively associated with sacrifice offered to their partners and they reported more positive emotions as a result. The interaction between attachment anxiety and nationality was significant. Specifically, in the U.S. sample, individuals with high attachment anxiety were more likely to offer sacrifice for their partners, but this effect was reversed in the Chinese sample. In addition, interdependent self-construal (ISC) was a significant moderator for the relation between attachment anxiety and sacrifice behavior. Individuals who endorsed higher ISC and higher anxious attachment were less likely to make sacrifice for their partner. Furthermore, when individual offered more sacrifice, they reported more positive …

Accuracy of Three Assessments of Sleep Timing, Duration and Efficiency Compared to a Single-Channel EEG Device (open access)

Accuracy of Three Assessments of Sleep Timing, Duration and Efficiency Compared to a Single-Channel EEG Device

Poor sleep measured across many dimensions has been linked to adverse physical and mental health outcomes including cardiovascular disease, diabetes, cancer, increased mortality, depression, and anxiety. Current research typically relies upon brief, subjective, inadequately validated methods to assess limited dimensions of sleep, resulting in inaccurate measurements and possibly faulty conclusions. Specifically, research validating objective (e.g., actigraphy) and subjective (e.g., sleep diaries, retrospective surveys) measurement methods against the gold standard of polysomnography (PSG, an overnight sleep study) is primarily limited by a) a lack of reliability based on too short (e.g., 24 or 48 hours) of an assessment period to capture night-to-night variability, b) a lack of ecological validity (e.g., full PSG in a laboratory setting), and c) a lack of generalizability due to limited or special populations (e.g., individuals with insomnia). Barriers such as prohibitive cost, extensive setup time, and personnel training requirements diminish the ability of researchers to conduct measurement comparison studies using gold standard measures like traditional PSG. These barriers can be circumvented with the use of low-cost, minimally invasive single-channel EEG devices (e.g., Zmachine), but to date few studies have employed these devices. The current study evaluated the accuracy of retrospective surveys, sleep diaries, and actigraphy compared …
