Return to Sport: Improving Athletes' Confidence and Mindset Post-ACL Surgery (open access)

Return to Sport: Improving Athletes' Confidence and Mindset Post-ACL Surgery

This study explored the impact of three psychological interventions over seven weeks - goal setting (GS), GS and imagery (IM), and GS and mindful self-compassion (MSC) - on 20 athletes' (Mage = 16.75 years) pain, cognitive appraisal, depression reinjury anxiety, psychological readiness to return to sport, and range of motion (ROM). IM and GS interventions have demonstrated initial effectiveness; however, no study has examined MSC in relation to post-ACL recovery. All athletes experienced significant decrease in pain (F(2) = 97.30, p = .000) from Week 1 to Week 7 and a significant increase in ROM from Week 2 to Week 7 (F(1) = 77.93, p = .000). All athletes experienced significantly higher depression at Week 1 compared to both Week 2 and Week 7 (F(2) = 9.01, p = .001), and significantly higher difficulty coping with their injury at Weeks 1 and 2 compared to Week 7 (F(2) = 6.32, p = .005). There were no statistically significant effects found between the intervention groups at Weeks 1, 2, and 7. However there were moderate effect sizes between interventions which suggest MSC and IM could help athletes cope with their injury during the first few weeks after surgery, and GS may …

The Effects of Multicultural Discussions and Supervisory Working Alliance on Multicultural Counseling Competence (open access)

The Effects of Multicultural Discussions and Supervisory Working Alliance on Multicultural Counseling Competence

This study examined the influence of multicultural training, multicultural discussions in supervision, and the supervisory working alliance on multicultural counseling competence. The sample consisted of 57 doctoral counseling interns, doctoral graduate students and post-doctoral students in counseling and clinical psychology. Participants completed several instruments including a demographic questionnaire, the Supervisory Working Alliance Inventory - Trainee, and the Multicultural Counseling Inventory. They filled out two questionnaires created for this study, one assessing multicultural discussions in supervision and another quantifying their multicultural training experience. Data analyses included multiple hierarchical regression, utilizing the Hayes PROCESS macro. Multicultural discussions in supervision moderated the relationship between the supervisory working alliance and multicultural counseling competence, but did not significantly moderate the relationship between multicultural training and multicultural counseling competence. Findings suggest that when multicultural discussions in supervision are positive, they significantly increases the strength of the relationship between good supervisory working alliance and multicultural counseling competence in psychology trainees. The findings may inform supervision practices and improve multicultural counseling competence in psychology graduate student trainees.

Co-Occurrence of Rape Myth Acceptance and Intolerant Attitudes in a Military Sample (open access)

Co-Occurrence of Rape Myth Acceptance and Intolerant Attitudes in a Military Sample

Sexual trauma within the military is a widespread issue, and rape myth acceptance has been shown to contribute to its prevalence. Given that the military culture has been shown to lend itself to hypermasculinity and traditional gender role adherence, both of which facilitate aggression toward women, this effect warrants investigation within a military sample. The present study replicated and expanded upon Aosved and Long's (2006) study examining 85 veteran and active duty military members' responses on the Illinois Rape Myth Acceptance Scale, Attitudes Toward Women Scale (short form), Neosexism Scale, Male Role Norms Inventory (short form), Modern and Old Fashioned Racism Scale, Modern Homophobia Scale, a modified version of the Economic Belief Scale, Fraboni Scale of Ageism, Religious Intolerance Scale, and the Marlowe–Crowne Social Desirability Scale (short form). Findings provide support for the co-occurrence of rape myth acceptance with intolerant attitudes, including sexism, hypermasculine gender role ideology, racism, sexual prejudice, classism, ageism, and religious intolerance, both individually and collectively. These results provide insight into the functioning of intolerant attitudes within a military sample, and provide important insight for future research addressing the association between rape myth acceptance and rape proclivity and the perpetration of military sexual assault.

Examination of a Bi-Directional Relationship between Urgency and Alcohol Use (open access)

Examination of a Bi-Directional Relationship between Urgency and Alcohol Use

The proposed study examined whether negative urgency and positive urgency are dynamic traits that hold bi-directional relationships with binge and prolonged alcohol use across time. Individuals between the ages of 18-30 were recruited from Amazon Mechanical Turk (MTurk; n = 179) and university student (n = 66) pools. Participants completed three batteries of self-report assessments approximately 30 days apart, each containing measures assessing negative and positive urgency, as well as drinking frequency and binge behavior during the prior month. Latent variable cross-lagged panel models examined the effects of alcohol use from the previous month on negative and positive urgency while controlling for concurrent and autoregressive effects. Results of the current study indicated that for the full sample, there was not an effect for the influence of binge/prolonged drinking on either negative or positive urgency during the subsequent month. However, when examined separately by sample (Turkers vs. university) and gender (male vs. female), significant effects were found more for individuals who were Turkers, male, and/or heavy drinkers, suggesting that increases in positive and negative urgency at Time 2 could be partially explained by variance in drinking patterns at Time 1 for these individuals. However, these relationships were not replicated again between …

Relationships Among Self-esteem, Psychological and Cognitive Flexibility, and Psychological Symptomatology (open access)

Relationships Among Self-esteem, Psychological and Cognitive Flexibility, and Psychological Symptomatology

Previous findings on the relationship between self-esteem and psychological outcomes are inconsistent. Therefore it appears that self-esteem, while related to crucial variables, does not provide a clear, direct, and comprehensive prediction of psychological symptoms. Thus, it was hypothesized that the relationship between self-esteem and symptomatology would be moderated by broader measures of how one interacts with emotional and cognitive stimuli.The purpose of this study was to examine the influence of self-esteem, psychological flexibility, and cognitive flexibility on psychological symptomatology. A sample of 82 undergraduate students at the University of North Texas completed self-report questionnaires measuring low self-esteem, psychological flexibility, measured inversely as inflexibility, cognitive flexibility, and psychological symptoms. Results of the study suggest that self-esteem (?= -0.59, p < 0.001) and flexibility (both psychological (?= 0.36, p = 0.001) and cognitive (?= 0.21, p < 0.05) are significant predictors of psychological symptoms. In other words, self-esteem is positively correlated with psychological symptoms, while psychological and cognitive flexibility are negatively correlated with psychological symptoms. Neither form of flexibility moderated the relationship between self-esteem and psychological symptoms in this sample. The findings of the current study are discussed as well as suggestions for further research related to self-esteem, psychological and cognitive flexibility, …

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) …

The Role of Attachment in Perceptions of Interparental Conflict and Behavior Problems in Middle Childhood (open access)

The Role of Attachment in Perceptions of Interparental Conflict and Behavior Problems in Middle Childhood

The current study investigated the association of interparental conflict, parent-child attachment, and children's behavior problems in middle childhood. Although the effects of interparental conflict have been studied extensively, there has been little research done in the developmental period of middle childhood. This study examined the potential mediating role of the attachment relationship between parents and children in a community sample consisting of 86 two-parent families with at least one child between the ages of 8-11. Path modeling procedures indicated that attachment security serves as a mediator between interparental conflict and child behavior problems based on child reports. In particular, child-reported attachment security to the mother significantly mediated the association between children's perceptions of threat from interparental conflict and child-reported internalizing and inattentive/hyperactive symptoms. Child-reported attachment security to the father was not a significant mediator and mediation was not supported in parent-report models. The current findings have implications for families experiencing conflict and speak to the importance of attachment in the parent-child relationship when explaining the association between instances of interparental conflict and child behavioral outcomes. In particular, parents who engage in conflict can prevent the damaging effects of that conflict by making the conflict less overt, explaining to children the …

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.

Early and Current Family Environment Among Inpatient Trauma Survivors: Associations with Multi-type Abuse and Sexual Orientation (open access)

Early and Current Family Environment Among Inpatient Trauma Survivors: Associations with Multi-type Abuse and Sexual Orientation

The present study is an exploratory analysis of associations among sexual orientation, childhood abuse, and characteristics of both early and current family environment in a sample of 80 inpatient trauma survivors. Participants were administered a background information questionnaire, Dissociative Disorders Interview Schedule, the Family Environment Scale and other instruments not analyzed in the current study. Multi-type abuse was significantly associated with low expressiveness and independence and high control in the early family, but no associations emerged with current family characteristics. Results suggest that the intergenerational transmission of family organization and moral-religious orientation occurred in the entire sample, and the transmission of family conflict patterns occurred only in the L/G/B group. Overall, participants perceived improvements in their current family environments compared to their early family environments. Findings yield support for the sexual minority stress model and mixed support for the intergenerational transmission of family characteristics.

The Influence of Extraversion, Religiosity, and Spirituality on Health Behaviors

Religion and spirituality are thought to be of great importance for the meaning and quality of life for many individuals, and research suggests that there may be important health benefits associated with religion and spirituality. Religion and spirituality should be related to health behaviors for a number of reasons. Health behaviors are important contributors to an individual's overall health, illness and mortality. Major negative health behaviors related to health outcomes are smoking, excessive alcohol consumption, obesity, risky driving, and high risk sexual behaviors. Health behaviors may also be linked to personality traits. The key trait examined for this study was extraversion. It includes adjectives such as being active, assertive, energetic, outgoing, and talkative. In this thesis, I take several hypotheses and explore the influence of extraversion, religiosity, and spirituality on health behaviors.

Reinforcement Sensitivity Theory and Proposed Personality Traits for the Dsm-v: Association with Mood Disorder Symptoms (open access)

Reinforcement Sensitivity Theory and Proposed Personality Traits for the Dsm-v: Association with Mood Disorder Symptoms

The current work assesses the relationship between reinforcement sensitivity theory (RST) and Personality Traits for the DSM-5 (PID-5), to explore the degree to which they are associated with mood disorder symptoms. Participants (N = 138) from a large public university in the South were administered a semi-structured interview to assess for current mood disorder and anxiety symptoms. They were also administered self-report inventories, including the Behavioral Inhibition System (BIS) and Behavioral Approach System (BAS) scales and the Personality Inventory for DSM-5 (PID-5). Results indicate that both the BIS/BAS scales and the PID-5 scales were strongly associated with current mood symptoms. However, the maladaptive personality traits demonstrated significantly greater associations with symptoms compared to the BIS/BAS scales. Results also indicated support for using a 2-factor model of BIS as opposed to a single factor model. Personality models (such as the five factor model) are strongly associated with mood symptoms. Results from this study add to the literature by demonstrating credibility of an alternative five-factor model of personality focused on maladaptive traits. Knowledge of individual maladaptive personality profiles can be easily obtained and used to influence case conceptualizations and create treatment plans in clinical settings.

Masturbation and Relationship Satisfaction (open access)

Masturbation and Relationship Satisfaction

Relationship satisfaction often declines after marriage or cohabitation and between 40-50% of marriages end in divorce. Furthermore, many couples who stay together report feeling unsatisfied in their relationships. Thus, it is important to examine factors that contribute to enduring and satisfying relationships. One factor that has been closely linked to relationship satisfaction is the sexual relationship of the couple. One aspect of the sexual relationship that has received little attention is masturbation. Although most psychologists hold positive views about masturbation, and recommend masturbation in many instances, the empirical data examining the association between masturbation and relationship satisfaction has mixed findings, with the majority of studies reporting a small negative relationship between these variables. The purpose of the present study was to further explore the association between masturbation and relationship satisfaction, focusing on possible moderators and mediators of this relationship including: masturbation guilt, openness with an individual's partner about masturbation, gender, object of arousal during masturbation, and reason for masturbating. Overall, masturbation frequency did not have a significant association with relationship satisfaction. However, the object of arousal during masturbation and openness about masturbation moderated the association between masturbation frequency and relationship satisfaction. Specifically, individuals who (a) used objects of arousal other …

Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory Approach (open access)

Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory Approach

Flashbulb memories are highly vivid and long-lasting memories for events that are emotionally significant and personally important. These memories are held in very high confidence in accuracy over an extended period. In particular, individuals believe that they can remember the personal details surrounding the event such as where they were and what they were doing at the time the event occurred. Evidence from research, however, indicates that this may not be the case. The study of flashbulb memories has typically been confined to negative events such as September 11, 2001. In the current study, we employ the methods of Talarico and Rubin (2003) to investigate flashbulb memory formation to a positive event. The event is the assassination of Osama bin Laden, which resonated as a highly positive event for many Americans evidenced by the thousands of people flooding the streets of Washington, D.C. and New York City to celebrate. We examined various memory properties over a one-year period, including vividness, rehearsal, belief in accuracy, and consistency. Results confirm the formation of flashbulb memories to the assassination event, but results did not support many of the proposed hypotheses. Some differences were found for different testing groups (i.e., immediate versus one week …

Attention Biases Associated with Vulnerability to Bipolar Disorder (open access)

Attention Biases Associated with Vulnerability to Bipolar Disorder

Bipolar disorder is associated with significant social and occupational impairments, as well as increased risk for substance abuse and suicide. More research is needed to identify potential mechanisms associated with vulnerability to the disorder. Previous research has identified altered processing of emotional information in bipolar and bipolar-prone individuals, including attentional biases which appear to differ based on the current affective state of the individual. The current study applied a sensitive measure of attention (i.e., eye-tracking) to assess whether vulnerability to bipolar disorder, as indexed by hypomanic personality traits, would be correlated with biases in attention to emotional facial stimuli, independent of mood state. Hypomanic personality traits were hypothesized to be associated with greater attention to happy and angry faces, as indexed by faster initial orientation, more frequent gazes, and longer gaze duration for these stimuli. Participants completed self-report measures assessing current mood symptoms, positive and negative affect, and hypomanic personality traits. They then completed two tasks assessing attention for emotional faces. The first was an eye-tracking task, which measured latency to first fixation, total gaze duration and total number of gazes for each emotional face category. The second was a spatial cueing task which assessed both attentional engagement with emotional …

Exploring Psychopathic Personality Traits and Moral Development in a Non-criminal Sample

This study explored psychopathic personality traits among a non-criminal, college undergraduate sample. Much research has been done on conceptualizing the construct of psychopathy, but this work has been conducted primarily with incarcerated individuals using a structured interview, The Psychopathy Checklist – Revised (PCL-R; Hare, 1991, 2003). The goal of the current study was to assess psychopathic traits among non-criminal individuals using The Self-Report Psychopathy Scale - Version Four (SRP-IV; Paulhus, Neumann, & Hare, in press), and compare how SRP-IV scores were associated with a well recognized semi-structured interview for psychopathy, The Psychopathy Checklist – Screening Version (PCL: SV; Hart, Cox, & Hare, 1995). The study also examined whether psychopathic personality traits could be predicted using a measure of normal-range personality, based on the five-factor model (FFM; Digman, 1990), and a measure developed by Loevinger (1976) related to ego development. Five-Factor Model Rating Form (FFMRF; Mullins-Sweat, Jamerson, Samuel, Olson, & Widiger, 2006) scores and Total Protocol Ratings (TPR score) on the Washington University Sentence Completion Test (WUSCT; Hy & Loevinger, 1996) were used to predict psychopathy scores.

Miranda Reasoning and Competent Waiver Decisions: Are Models of Legal Decision Making Applicable? (open access)

Miranda Reasoning and Competent Waiver Decisions: Are Models of Legal Decision Making Applicable?

Miranda understanding, appreciation, and reasoning abilities are essential to courts' determinations of knowing and intelligent Miranda rights waivers. Despite the remarkable development of Miranda research in recent decades, studies have generally focused on understanding and appreciation of Miranda rights, but have not examined Miranda reasoning and waiver decisions. Therefore, examining the nature of defendants' decisional capacities constitutes a critical step in further developing theoretical and clinical models for competent Miranda waiver decisions. The current study evaluated Miranda waiver decisions for 80 pretrial defendants from two Tulsa-area Oklahoma jails. Previously untested, the current study examined systematically how rational decision abilities affect defendants' personal waiver decisions. Components from general models of legal decision making, such as decisional competence and judgment models, were examined to determine their applicability to Miranda waiver decisions.

Impact of Clinician Expectations on Termination Status and Therapeutic Outcome (open access)

Impact of Clinician Expectations on Termination Status and Therapeutic Outcome

Given the high rates of premature termination in training clinics, research aimed at understanding client attrition is urgently needed. Recent investigations in this area have implicated expectations of psychotherapy as a strong predictor of premature termination; however, this phenomenon has only been studied from the perspective of client expectations to date. There is reason to believe clinician expectations for the duration and effectiveness of psychotherapy may further impact the likelihood of their clients terminating prematurely. This study sought to address this gap in the literature by examining the association of clinicians' expectations to clients' psychotherapy outcomes and termination status in a training clinic setting. Clinicians were found to hold significantly higher expectations for client improvement than would be expected, and these high expectations were found to be positively correlated with clinically significant change in clients. Implications for improving client retention and treatment outcome in training clinics are discussed.

This study is part of a larger research project examining family attachment processes. The current study tests a family process model that postulates the mediating role of parent-child attachment and sibling relationship quality in the associations of parent psychopathology or marital adjustment to children's psychological dysfunction. A community sample of 86 families with at least one school-aged (8-12 years) child was recruited from area schools and organizations. Families came to the UNT Family Attachment Lab, where they participated in research tasks, including interviews, self-report instruments, and videotaped interaction tasks. Specific questionnaires used in this study included the Sibling Relationship Questionnaire, the Security Scale, the Behavior Assessment System for Children, the Symptom Assessment-45 Questionnaire, and the Dyadic Adjustment Scale.

Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy

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

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 (&#945; = .94), Freedom from Values Conflict (&#945; = .92), and Flexibility in Valuing (&#945; = .73). The majority of expected relationships with other constructs were significant including those with measures of values, mindfulness, quality of life, experiential avoidance, and psychological distress.

The Relationship between Physical Activity and Sleep

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

Optimism, Delay Discounting, and Physical Exercise: The Role of Delay Discounting on Individual Levels of Exercise

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