The beginning of college is a period in which increased alcohol use often coincides with greater involvement in romantic relationships. Existing literature yields inconsistent findings regarding the influence of different relationship statuses on drinking behavior, perhaps because these studies have not accounted for recent changes in the way college students engage in dating/sexual relationships. In the current college environment, many students who define themselves as non-daters are nonetheless sexually active, a phenomenon referred to as the 'hook up' culture. The present study sought to address this issue by examining the effects of both relationship status and sexual activity on heavy episodic drinking (HED) among 1,467 college students over the course of their first three semesters. Results indicated that the effects of relationship status depended on whether or not an individual was sexually active. Non-dating but sexually active students reported rates of heavy drinking comparable to students who defined themselves as casual daters, but non-dating students who were not sexually active reported drinking behavior similar to those involved in committed relationships. Further, transitions between low and high risk relationship/sexual activity statuses were associated with corresponding changes in HED. Transitioning into a high risk status was associated with greater levels of heavy episodic drinking, whereas transitioning into a low risk status was associated with decreases in this behavior. Together, results indicate that engaging in nonexclusive dating or sexual relationships may play an important role in the development of problematic patterns of alcohol use during the early college years. These findings have potentially important implications both for future research and for prevention and intervention efforts targeting high risk college drinkers.

Research has suggested that lonely people demonstrate distinct differences from nonlonely people in their behaviors, mood, and interpersonal experiences. Lonely people who are also enduring a chronic pain condition may be at an especially high risk for negative outcomes because of simultaneous issues such as stigma, mood disturbances, and pain-related disability. The current study examined chronic and transitory loneliness in a sample of 123 chronic pain patients. Participants completed daily diaries assessing the occurrence of positive and negative interpersonal events, appraisals of interpersonal events, pain, and mood. Multilevel modeling was used to examine effects of being a lonely person as well as having a lonely episode on daily life. Results indicated that both chronic and transitory loneliness were associated with more frequent negative and less frequent positive interpersonal events, higher levels of pain, more negative and less positive affect, and more stress and less enjoyment from social interactions. Loneliness did not affect reactivity to negative interpersonal events, but did influence responsivity to positive interpersonal events such that lonely people had greater boosts in enjoyment when experiencing more positive interpersonal events than usual. These findings suggest that both lonely people and individuals experiencing a lonely episode experience more negative consequences in their daily lives than nonlonely people. However, they can benefit from engaging in more frequent positive interpersonal events, which can help to inform future clinical interventions for lonely, chronic pain patients.

Introduction: Edibles, THC-infused food products, are a popular type of cannabis. However, there is limited research on how acute effects of edibles differ from more traditional cannabis types, such as smoked flower (e.g., dried bud). The current study examined the subjective response of cannabis between smoked flower and edibles using a two-week long ecological momentary assessment (EMA). Sex differences were also examined.Method: Individuals (n=101) using both edibles and flower at least once weekly completed a cannabis report within 30 minutes (T1) of first cannabis use each day as well as two follow-up reports sent 1.5 (T2) and 3 hours (T3) after initial use. Participants additionally completed assessments throughout the day for fourteen consecutive days to examine daily affect. Multi-level models examined whether overall high, low-arousal negative effects, high-arousal negative effects, and general positive effects differed by edibles and flower. Given time differences in effects between cannabis types, subjective effects were examined at T1, T2, and T3, as well as for the peak effects across the three-hour time window. Covariates included demographics, variant- and invariant- cannabis use characteristics, and daily affect. Results: At T1, edibles produced lesser positive effects (b=-0.60, S.E.=0.16, p=0.001) and overall high (b=-2.00, S.E.=0.27, p<0.001) relative to flower. At T2, edibles produced greater positive effects (b=0.52, S.E.=0.21, p=0.01) relative to flower. At T3, edibles produced greater low-arousal negative effects (b=0.63, S.E.=0.23, p=0.01) relative to flower. Edibles produced greater peak low-arousal effects relative to flower (b=0.59, S.E.=0.21, p=0.01), With respect to sex differences, there was an interaction between sex and cannabis type at T1 for positive effects (b=-0.99, S.E.=0.31, p=0.001), such that males reported greater positive effects for flower. Males additionally reported lesser low-arousal effects at T1 (b=-0.60, S.E.=0.30, p=0.05) and greater overall high at T3 relative to females (b=1.24, S.E.=0.56, p=0.03). Discussion: Smoked flower produced greater effects immediately and edibles produced greater delayed effects. Edibles appear to have greater peak levels of low-arousal effects (e.g., sluggish, drowsy, slow) relative to smoked flower. Males may be more sensitive to the rewarding effects of cannabis, particularly when smoking flower.

Over 35% of multiracial college students fail to earn a degree, which can have significant economic and health costs over their lifespan. This study aimed to better understand college and psychological adjustment among multiracial college students of Hispanic/Latinx and White non-Hispanic descent by examining students’ racial identities and use of resilience resources. Latent profiles of identity were identified to better understand how different aspects of racial identity are clustered in this population. Multiracial college students (N=221) reported on racial identity as measured on multiple dimensions: Hispanic/Latinx identity, Hispanic/Latinx cultural orientation, White identity, identity integration, shifting expressions of identity, and identity malleability. Students also reported on their use of multiple resilience resources (personal mastery, social competence, perspective taking, coping flexibility, familism support values) and both college and psychological adjustment. Through regression and SEM analyses, results indicated that, of the resilience resources, only personal mastery was positively related to both college and psychological adjustment, while social competence was positively related to college adjustment. More shifting expressions of identity was related to poorer college and psychological adjustment, which was partially mediated via personal mastery. Stronger Hispanic/Latinx identity was related to higher perspective taking and coping flexibility, while stronger White identity was related to higher familism support values. Latent profiles of identity indicated a four-class solution, consisting of 1) “low identity”, 2) “integrated, low shifting”, 3) “integrated, shifting”, and 4) “high shifting, low integration”. Findings highlight the need for person-centered and ecological approaches to understanding identity development and resilience among multiracial college students, and can inform prevention and intervention efforts for multiracial college students of Hispanic/Latinx and White non-Hispanic descent. Results also demonstrate the importance of assessing multiracial identity via multiple dimensions including factors such as identity integration, shifting expressions of identity, and identity malleability.

Research on self-regulatory variables like mindfulness and effortful control proposes strong links with physical and mental health outcomes across the lifespan, from childhood and adolescence to adulthood and old age. One pathway by which self-regulation may confer health benefits is through individual differences in reports of and emotional responses to daily negative and positive events. Mindfulness is broadly defined as non-reactivity to inner experiences, while effortful control is broadly defined as attentional and behavioral regulation. Mindfulness and effortful control have both been conceptualized to exert their beneficial effects on development through their influence on exposure/engagement and emotional reactivity/responsiveness to both negative and positive events, yet few empirical studies have tested this claim using daily-diary designs, a research methodology that permits for examining this process. With a sample of community-dwelling adults (n=191), this thesis examined whether dispositional mindfulness (i.e., non-reactivity of inner experience) and effortful control (i.e., attention and behavioral regulation) modulate reports of and affective reactivity/responsiveness to daily negative and positive events across 30 days. Results showed that mindfulness and effortful control were each associated with reduced exposure to daily stressors but not positive events. They also showed that mindfulness and effortful control, respectively, predicted smaller decreases in negative affect and smaller increases in positive affect on days that positive events occurred. Overall, these findings offer insight into how these self-regulatory factors operate in the context of middle-aged adults’ everyday life.
