In the current study, I examined the efficacy of mindful self-compassion, imagery, and goal-setting (i.e., treatment as usual) interventions on athletic identity, knee self-efficacy, subjective knee functioning, and perceived injustice, following ACL surgery. Twenty-nine adolescent and young adult athletes participated in the interventions and completed self-report measures assessing each of these constructs prior to their surgery and over seven weeks post-ACL surgery. HLM analyses demonstrated significant decreases in athletic identity and increases in subjective knee functioning from pre-surgery through seven weeks post-surgery. Intervention group further explained these decreases, though no one intervention clearly emerged as more or less beneficial. No significant changes were observed for athletes' ratings of knee self-efficacy or perceived injustice. Limitations and areas for future research are discussed.

The current study used a sample of service members and veterans to explore the association of combat exposure and perceptions of the family system using a moderated mediation model. Combat veterans over the age of 18 with a family of creation (N = 154) completed an online survey through which they were administered a background information questionnaire, the Combat Experiences subscale of the Deployment Risk and Resilience Inventory – 2, the Moral Injury Events Scale, the PTSD Checklist for DSM-5, the Patient Health Questionnaire, the Beck Anxiety Inventory, the McMaster Family Assessment Device, and the Dyadic Adjustment Scale – Revised. Results of six moderated mediation analyses revealed that exposure to potentially morally injurious events (pMIEs) moderated the relationship between (1) combat exposure and couple relationship satisfaction and (2) combat exposure and family functioning, both via PTSS, anxious symptoms, and depressive symptoms. To our knowledge, the empirical models presented in this paper are the first to model the role of pMIEs in SMV literature, and provide a foundation for other models to emerge moving forward. Implications and limitations are discussed.

Tears to the anterior cruciate ligament (ACL) represent a serious sport injury that can be physically and psychologically debilitating for athletes. Recovery from ACL surgery is a six to nine month process, though the first four months of rehabilitation represents the key time of recovery. Thus, psychological interventions should occur during these first four months, but then examine athletes' psychological and physical functioning over the longer term. Past research has supported the efficacy of goal setting and imagery in helping athletes during their ACL recovery, and MSC has been shown to help athletes regulate emotions and improve their sport performance. MSC-based interventions, however, have not been examined in relation to injured athletes' psychological functioning and physical recovery. Thus, I examined the relative effects of three psychological interventions (i.e., GS, IM, and MSC) on athletes' post-ACL responses. Overall, I found no significant differences in the effects of GS, IM, or MSC on athletes' athletic identity, confidence in returning to sport, reinjury anxiety, stress related to sport injury, perceptions of ability to cope with injury, and subjective knee functioning. Although non-significant, athletes in the GS group showed slightly larger rates of change in their reinjury anxiety and cognitive appraisal compared to athletes …

This study examined the direct and indirect associations of the perceived coach-created motivational climate, athletes' implicit theory, and athletes' achievement goal orientation in relation to their levels of grit. Five hundred twenty-three Division I and II collegiate student-athletes (male = 246, female = 277) from five institutions across the south-central and southeast areas of the United States completed self-report measures assessing the previously described constructs. The measurement model fit the data well (SRMR = .055; CFI = .938; RMSEA = .067) and demonstrated invariance across the male and female athletes. The structural model demonstrated adequate fit (SRMR = .088; CFI = .918; RMSEA = .068). All direct and indirect paths in the model were significant in the expected direction, with the exception of the direct path from entity theory to ego goal orientation and the indirect path from ego-involving climate to ego goal orientation through entity theory, which were both non-significant. The mastery-incremental constructs accounted for 65% of the variance in grit. Results indicate that achievement motivation theory is an appropriate framework through which to examine grit, and achievement motivation constructs may be significant antecedents of grit's development. Limitations and future directions are discussed.

Many religious/spiritual (R/S) individuals receive meaning from R/S and utilize R/S to help them cope with stressful life events. However, natural disasters can disrupt the R/S meaning-making process (e.g., positive R/S coping strategies) because natural disasters can elicit cognitive dissonance between one's core R/S beliefs and personal disaster experience. R/S individuals suffering from a disaster experience could benefit from interventions that allow them to process their R/S experiences. The purpose of this dissertation is to fill a gap in the literature by exploring the effectiveness of a spiritually-oriented expressive writing intervention on positive psychological outcomes (e.g., meaning in life, satisfaction with life) in 132 R/S individuals that have experienced a natural disaster (i.e., survivors of the 2016 Baton Rouge, Louisiana flood). Quantitative results indicated the spiritually-oriented intervention was effective in promoting increased meaning in life but not life satisfaction. Survivors with lower pre-intervention positive attitudes toward God evidenced the strongest positive impact on their meaning in life. Qualitative analyses, using the constant comparative method from Corbin and Strauss's grounded theory approach, revealed six themes in the experimental group's written responses: (a) R/S growth, (b) R/S struggle, (c) R/S cognitive dissonance, (d) R/S reappraisals, (e) R/S proximity-seeking, and (f) spiritual support …

Although the overall quantity of international research has increased, existent studies tend to adopt an instrument developed in one culture to use in the other, leading to measurement bias. In addition, previous cross-cultural research mainly focuses on comparisons between collectivist and individualistic backgrounds (e.g., American vs. Chinese) without considering the similarities and differences within the collectivist societies (e.g., China vs. Mexico). This dissertation project has two purposes, with Study 1 aiming to examine measurement equivalence of two widely used instruments while Study 2 investigating if an attachment-based two-serial mediation model remained constant among three cross-cultural samples collected from the US, Mexico, and China. A total of 1211 participants, including 360 American university students, 441 Mexican students, and 410 Chinese students participated in the study. Differential item functioning (DIF) in lordif package in R and structural equation modeling (SEM) in Mplus 8.1 were adopted for Study 1 and 2, respectively. The results of Study 1 indicated the proposed instruments were culturally invariant in English, Spanish, and Chinese with some modifications. Study 2 showed that assertiveness/self-conscious emotions mediated the association between adult attachment and depression/aggression only in the US group. However, the two-serial mediation model in which the link between adult attachment …

Childhood maltreatment by a caregiver can occur in many forms, ranging from overt abuse to more subtle neglect. Amidst a primary focus on the outcome of posttraumatic stress disorder (PTSD), less research attention has been given to understanding the impact of maltreatment on one's developing sense of self, internal working model (IWM) of relationships, and emotion regulation capacities. Difficulties experiencing, regulating, and enjoying a full range of affect are common transdiagnostic features among adult survivors of child maltreatment, who frequently display emotional reactivity (e.g., mood swings, anger) and/or disengagement (e.g., numbing, dissociation). What makes the difference between individuals who lash out in emotional outbursts, those who tend to withdraw or dissociate, and those who frequently alternate between these two affective poles? In a mixed college and community sample of 417 adults, we explored two covert forms of childhood emotional maltreatment (e.g., chronic emotional disengagement and frightened/helpless parenting) as potentially linked to adult psychological and relational functioning. Controlling for the effects of childhood physical and sexual abuse, path analysis indicated that these types of maltreatment were significantly associated with insecure attachment patterns, emotional reactivity, and dissociation in adulthood. These findings inform therapeutic work with survivors of childhood trauma, signifying the importance …
