Issues In Contrasting Conservative And Considered Estimation: A Reply To Bobko Et Al. (2024), Paul R. Sackett, Christopher M. Berry, Filip Lievens, Charlene Zhang

Research Collection Lee Kong Chian School Of Business

Bobko et al. (2024) responded to Sackett et al.'s (2022) compilation of meta-analytic evidence for the validity of a wide variety of measures used as predictors of overall job performance, offering a set of alternative methodological choices which they term “considered estimation” to counter the Sackett et al. approach of “conservative estimation.” Here we offer a rebuttal to Bobko et al. A primary concern is that Bobko et al. apply the label “conservative estimation” to the full range of methodological choices made by Sackett et al. Yet, we clarify the narrow and specific meaning of “conservative estimation,” and note that …

The purpose of this research project is to gain rehabilitation therapists’ perspectives on AI/ML in post-stroke assessment and intervention.Design: This ongoing study uses a mixed methods design with surveys and focus groups. Participants engaged in a 30-minute webinar to learn …

The Acute Effects Of Tetrahydrocannabivarin (Thcv) On Appetite, Caroline M. Sokol

Masters Theses, 2020-current

The purpose of the current study was to assess the acute effects of tetrahydrocannabivarin (THCV) on appetite. Participants (N = 28) experienced 12.5 mg THCV, 25mg THCV, and placebo in counterbalanced order across three, 3-hr experimental sessions. Following baseline procedures, participants consumed THCV or placebo and completed self-report measures every 30 minutes. A series of repeated measures factorial ANOVAs were conducted to examine potential differences in study outcomes across THCV dosing conditions as well as within session (i.e., baseline, every 30 minutes after dosing (5), end of session) with respect to self-reported hunger, mood, and perceived drug effects (e.g., …

Subjective Socioeconomic Status Moderates Self-Esteem Reactivity To Daily Stressor Exposure: Evidence From A Daily Diary Approach, Yi Jing Chua, Nadyanna M. Majeed, Verity Yu Qing Lua, Chi-Ying Cheng, Andree Hartanto

Research Collection School of Social Sciences

Research on self-esteem reactivity has demonstrated that self-esteem fluctuates in response to daily stressor exposure, and the strength of this relationship varies between individuals. Drawing upon the positive link between objective socioeconomic status (SES) and self-esteem, how subjective SES influences self-esteem reactivity to daily stressor exposure was explored. Using a 7-day daily diary study, the current study (N-participants = 243, N-days = 1651) adopted a multilevel analysis to demonstrate that subjective SES attenuated the within-person association between daily stressor exposure and daily self-esteem, even after controlling for demographics and objective indicators of SES. The interactions were also consistent across social …

I See Sick People: Beliefs About Sensory Detection Of Infectious Disease Are Largely Consistent Across Cultures, Joshua M. Ackerman, Theodore Samore, Daniel M. T. Fessler, Norman P. Li, Et Al

Research Collection School of Social Sciences

Identifying cues to contagious disease is critical for effectively tracking and defending against interpersonal infection threats. People hold lay beliefs about the types of sensory information most relevant for identifying whether others are sick with transmissible illnesses. Are these beliefs universal, or do they vary along cultural and ecological dimensions? Participants in 58 countries (N = 19,217) judged how effective, and how likely they were to use, cues involving each of the five major sensory modalities in an imagined social interaction during a flu outbreak. Belief patterns were strongly consistent across countries (sight > audition > touch > smell > taste), suggesting a largely …

Efficacy Of Digital Mental Health Interventions For Attention-Deficit Hyperactivity Disorder: A Meta-Analytic Review Of Randomised Controlled Trials, K. T. A. Kasturiratna, Andree Hartanto, Angel Khaterina Lee, Charmaine Jiali Koh, Nadyanna M. Majeed

Research Collection School of Social Sciences

Attention-Deficit Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder that significantly impacts various facets of life. While traditional treatments such as medication and behavioural therapy are effective, they often fall short due to limited access and undesirable side effects. In response to these limitations, digital mental health interventions have emerged as a transformative approach in alleviating ADHD symptoms. The current meta-analysis investigates the effectiveness of digital mental health interventions for ADHD synthesising data across 23 randomised controlled trials, with 99 effect sizes across 1,472 participants. Results showed small, significant effects of digital mental health interventions in reducing overall ADHD symptoms …

Socioeconomic Status Shapes Dyadic Interactions: Examining Behavioral And Physiologic Responses, Jacinth J. X. Tan, Tessa V. West, Wendy B. Mendes

Research Collection School of Social Sciences

With more opportunities for diverse interactions, little is known about how social interactions involving people of different socioeconomic status (SES) may unfold. We investigated social attunement patterns in dyadic interactions involving SES. Unacquainted individuals recruited from the community interacted with similar-or-different-SES partners in the lab (Ndyads = 130). Attunement was assessed throughout the interaction by examining physiological linkage—how much a person’s physiological change is predicted by another’s physiological change, over time. Overall, low-SES participants showed stronger physiological linkage—indicating greater attunement—to partners across SES. Participants also appeared more comfortable when interacting with low-SES partners. There were no SES differences in dominance …

A Lifespan Perspective On Positive Affect Fluctuations On Purpose In Life: Findings From A 9-Year Longitudinal Study, Jonathan L. Chia, Verity Y. Q. Lua, Andree Hartanto

Research Collection School of Social Sciences

Existing research has examined how static or average levels of positive affect (PA) influence purpose in life (PIL), but theoretical work suggests PA fluctuations may also play a role, potentially undermining PIL, especially in older adulthood. To this end, the present study examined the longitudinal association of PA fluctuations on PIL and the moderating role of age among 1,294 midlife and older adults in the United States, over a 9-year period (between 2004 and 2014). Results revealed a conditional effect of PA fluctuations on PIL – particularly among older individuals, and greater PA fluctuations were associated with a poorer sense …

Longitudinal And Bidirectional Relations Between Problematic Social Media Use And Cognitive Failures, K. T. A. Sandeeshwara Kasturiratna, Andree Hartanto

Research Collection School of Social Sciences

With social media becoming increasingly pervasive in our daily lives, there have been heightened concerns that the distractions caused by compulsive and problematic social media use may lead to cognitive failures. While some preliminary work have explored the link between problematic social media use and cognitive functioning, most are cross-sectional, leaving it uncertain whether cognitive failures are a precursor or consequence of problematic social media use. To address this gap, the current study examines the bidirectional relationship between problematic social media use and cognitive failures. A sample of 252 young adults completed the Problematic Social Media Use Scale and the …

Understanding The Physical Health Associations Of Intra-Individual Variability In Life Satisfaction Among Older Adults, Frosch Y. X. Quek, Kenneth Tan, David Chan

Research Collection School of Social Sciences

It is well established that inter-individual differences in life satisfaction positively predict health, but it is less clear how intra-individual variability in life satisfaction across time could influence health, particularly across individuals with different satisfaction levels. To address this gap, we analysed a large panel dataset from a national sample of 8,674 older adults, aged 50–70 (M = 59, SD = 5.42) in Singapore who completed surveys over 53 consecutive months. Results from multi-level modelling showed an interaction between variability in life satisfaction and life satisfaction mean on physical health. Specifically, there was no association between variability and health among …

Language Brokering Conditions The Indirect Association Between Mexican‐Origin Adolescents’ Academic Discrimination And Educational Expectations, Su Yeong Kim, Yayu Du, Chantal Alvarado, Wei Xiang Sim, Wen Wen, Tianlu Zhang, Jingyi Shen

Research Collection School of Social Sciences

Mexican‐origin adolescents, a significant portion of the US Latino population, often experience a decline in educational expectations from early to late adolescence. Contextual factors such as academic discrimination and language brokering for parents may contribute to this decline. This study investigates the indirect effect of academic discrimination experienced in middle school on educational expectations in young adulthood through high school grades and engagement, and the moderating role of language brokering experiences in these relations. Data were collected from 604 Mexican‐origin adolescents across four waves from 2012 to 2023. Academic discrimination experiences in middle school were negatively associated with school grades …

More Arguments For The Weakness Of The Empirical Evidence Used To Support Spanking Bans: Rejoinder To Afifi Et Al. (2025) And Kraus De Camargo (2025), Marjorie Lindner Gunnoe, Robert E. Larzelere, Christopher J. Ferguson, Ronald B. Cox Jr.

University Faculty Publications and Creative Works

In this rejoinder we address 13 concerns elicited by our invited commentary “An update on the scientific evidence for and against the legal banning of disciplinary spanking.” In addition to defending assertions made in the initial commentary, we make several new substantive arguments. In response to dissenters’ equating of non-experimental evidence against spanking with nonexperimental evidence against smoking, we demonstrate that the two are very dissimilar. We question the purpose of spanking bans, providing stronger evidence that they do not seem to prevent child abuse. We review Canada’s association with the UN’s Convention on the Rights of the Child (CRC) …

Resilience Redefined: Exploring The Impact Of Childhood Trauma On The Value Systems Of High-Achieving Corporate Men, Lana B. Henry

Graduate Theses and Dissertations

This qualitative study employed Interpretive Phenomenological Analysis (IPA) to explore how childhood trauma influences the value systems of high-achieving corporate men. In contemporary corporate culture, where stoicism, performance, and independence are often rewarded, little attention is paid to how early adversity informs internal frameworks of meaning, leadership, and success. Semi-structured interviews were conducted with six high-achieving men, all executives and leaders in high-performing industries, who self-identified as having experienced childhood trauma. Data were analyzed using a six-step IPA process and interpreted through the lens of Schwartz’s Theory of Basic Human Values and social constructivism. Findings revealed that childhood trauma deeply …

Seeking Existential Meaning In The “Sea Of Trees:” A Qualitative Exploration In The Depths Of Japan’S Aokigahara “Suicide” Forest, Sophia Bates

Masters Theses, 2020-current

This thesis explores the intercultural perceptions of suicidality and the role that these perceptions have on meaning of life in Japanese culture through an exploratory, autoethnographic analysis of my journey walking through Japan’s Aokigahara “suicide” Forest. In June 2024, I traveled to Fujikawaguchiko, Japan to conduct an autoethnographic analysis of my experiences walking through Aokigahara Forest using shinrin-yoku and mindful walking (Jung, 2014) as supplemental research methodologies to make empirical observations and take notes on my journey walking through suicide forest as an embodied sensory experience. Drawing upon the research and ideas of cultural anthropologist and existential philosopher Ernest Becker, …

Monitoring And Understanding Momentary Affect Intensity From Smartphone Sensors: Investigating The Role Of Time Resolutions And Semantic Locations, Yiqin Zhu

Arts & Sciences Graduate Student Theses and Dissertations

Momentary affect intensity refers to the momentary strength or intensity of emotional experience and shows wide associations with critical psychological and behavioral phenomena. Traditional self-report approaches to assess affect intensity require people’s attention and are prone to missingness and recall bias. Wide and cheap smartphone access offers opportunities to monitor and understand real-time affect intensity. This study had three specific aims: (a) To evaluate the potential for a state-of-the-art explainable artificial intelligence (AI) algorithm to predict momentary affect intensities without active inputs, we tested how well Temporal Fusion Transformers (TFTs) can predict momentary affect intensity in an unseen test sample; …

Psychology Faculty Research and Publications

Objective

Prenatal glucocorticoids (e.g., cortisol) are a widely proposed prenatal programming mechanism, yet few studies directly measure fetal cortisol. Neonatal hair provides a non-invasive method to assess fetal cortisol. The current studies test the association between maternal exposure to discrimination and fetal cortisol, as measured in neonatal hair, in two cohorts.

Methods

Study 1: Pregnant individuals (N = 65) and their neonates (61.8 % female) participated in study 1 between 2017 and 2021. Participants self-identified as Asian (6.2 %), Black (21.5 %), Latinx (35.4 %), Multiracial or Multiethnic (35.4 %), and Native Hawaiian or Pacific Islander (1.5 %). Experiences …

Testing An Ironic Process Model Of Emotion Expression In Daily Life, Laura B. Kenneally

Psychology Theses & Dissertations

Expressive suppression, or suppressing the expression of an emotion, is a common emotion regulation approach that has been found to have substantial negative implications for one’s mental health, physical health, and relationship functioning. However, expression of emotion, and of negative emotion in particular, has not consistently been found to be beneficial for mood or relationships. Moreover, the social expression of emotion that is culturally valued among Black-identifying Americans is different in White-identifying Americans, particularly in regard to expression of negative affect. However, it is unknown whether this cultural context mitigates the potential consequences of expressive suppression and emotion expression.

Expressive …

Exploring The Relationship Between Cannabis Use Motives And Readiness To Change Among Young Adult College Students, Emma Kathryn Rawls

Psychology Theses & Dissertations

Cannabis use among young adult college students has risen steadily over the past decade, raising concerns about the associated health, academic, and psychological consequences. While cannabis use motives and readiness to change have each been linked to use patterns and outcomes, limited research has examined how these factors interact. The current study investigated whether readiness to change, based on the Transtheoretical Model (TTM), moderates the relationship between cannabis use motives and cannabis-related consequences as well as past-30-day use frequency. A sample of 100 college students 18-25 years old (M_age = 20.08, SD = 2.12; 67% female; 55.0% Black or …

Drinking To Compensate: Expanding Upon The Motivational Model Of Alcohol Use, Douglas J. Glenn

Psychology Theses & Dissertations

The motivational model of alcohol use identifies four key drinking motives – coping, conformity, social, and enhancement – as important proximal antecedents of problematic drinking. However, applications of this model have been inconsistent in explaining drinking outcomes. Specifically, it is unclear under which conditions each drinking motive can be a risky or benign indicator of drinking behaviors. The current study theorized that a problematic drinking to compensate behavior could emerge across all drinking motives when alcohol is used to counteract a psychosocial (i.e., nondrinking) deficit. It was hypothesized, at the cross-sectional and daily level, that the associations between each drinking …

The Relationship Between Perceived Racial Discrimination And Psychological Distress: The Role Of Psychological Inflexibility, Kyrah Breann Frank

Electronic Theses, Projects, and Dissertations

Research has shown that marginalized groups experience perceived racial discrimination as traumatic, humiliating, and hurtful (Brown-Iannuzzi et al., 2014). Multiple studies have associated perceived racial discrimination with physical and mental health outcomes such as depression (Brown-Iannuzzi et al., 2014.; Shallcross & Spruill, 2017; Zapolski et al., 2018), cardiovascular problems (Watson-Singleton et al., 2019; Zapolski et al., 2018), anxiety (Zapolski et al., 2018), and stress (Graham et al., 2013; Watson-Singleton et al., 2019). Studies have also shown that mindfulness buffered/moderated the relationship between perceived racial discrimination and health outcomes (Brown-Iannuzzi et al., 2014; Graham et al., 2013; Shallcross & Spruill, 2017; …

Building Safer Spaces:Exploring Supportive Leadership And Remote Work As Strategies Against Lgbtqia+ Mistreatment, Saray Valenzuela Jaime

Electronic Theses, Projects, and Dissertations

Organizations worldwide are undergoing significant transformations driven by employees’ demands for healthier, more inclusive workplaces (Mercer, 2022). This shift amplified by the influx of Gen Z and Millennial workers, whose higher rates of lesbian, gay, bisexual, transgender, queer/questioning, intersex, and asexual (LGBTQIA+) identification have nearly doubled the proportion of sexual- and gender-minority employees over the past decade, reshaping work dynamics. Yet, nearly half of all LGBT employees experience unfair treatment based on their gender identity or sexual orientation (Sears et al., 2021). LGBTQIA+ identity and hostile workplace climates, marked by mistreatment and discrimination, negatively impact organizational effectiveness by undermining employee …

Clocking Out: Experiences Of Customer Sexual Harassment, Coping, And Psychological Well-Being Among Waitresses, Paola Lopez

Electronic Theses, Projects, and Dissertations

Workplace sexual harassment (WSH) is an ongoing issue which has been growing in literature especially when looking at the effects of WSH on employees. Yet, few studies have looked at workplace sexual harassment that occurs from customers towards employees known as customer sexual harassment (CSH). The current study investigates the role of coping strategies as a moderator when responding to CSH and the effects on employees' short- and long-term psychological well-being in terms of anxiety and depression.

How Was Rehab? A Follow-Up To A Randomized Effectiveness Control Trial Of A Brief Acceptance And Commitment Therapy Protocol For Inpatient Detoxification Patients, Alexander J. Twohy

Dissertations

Residential treatment for Substance Use Disorders (SUD) is a common treatment modality. However, the literature is sparse on modifiable predictors that affect change during the residential treatment stay. Acceptance and Commitment Therapy (ACT) has been shown to be an effective treatment for SUDs. Weststrate et al. (2023), in a randomized controlled effectiveness trial, compared ACT plus medication management to medication management during detoxification. The addition of ACT increased consumer satisfaction and ACT skills use, while decreasing psychological inflexibility and reducing withdrawal symptoms.

This study explored whether the brief ACT intervention had impacts during participants' subsequent residential stay. Forty out of …

Historically Minoritized Racial Groups At A Midwestern University: Behaviors, Attitudes, And Beliefs Toward Mental Health And Well-Being, Kemmel Palmer

Dissertations

The rising prevalence of mental health concerns among college students, especially those from historically minoritized racial groups, underscores persistent disparities and substantial barriers encountered within Predominantly White Institutions (PWIs). This qualitative inquiry examined the mental health behaviors, attitudes, and beliefs of college students from five historically minoritized racial groups—Black/African American, Latino/Hispanic, Asian Pacific Islander Desi American, Middle Eastern/Middle Eastern American, and Indigenous/Native American—at a midwestern university. Utilizing a phenomenological methodology, the study employed five focus groups comprising 51 participants representing a wide range of academic levels, gender identities, and sociocultural backgrounds.

The findings from this study reveal deeply embedded and …

Examination Of The Association Between Parent Beliefs About Injury And Supervision Behavior, Felicia Acelia Diaz

Dissertations

Unintentional Injuries are the leading cause of death for children in the United States (Centers for Disease Control and Prevention, National Center for Injury Prevention and Control, 2021). Several studies have indicated that caregiver beliefs (such as locus of control) are associated with children’s injury risk (Damashek et al., 2005), but few studies have examined whether caregiver beliefs about injury are related to caregiver’s injury prevention behaviors, such as caregiver supervision. Examination of caregiver beliefs regarding supervision revealed that caregiver’s degree of belief in the preventability of childhood injuries predicted self-report scores on several measures of supervision. Caregiver’s degree of …

"It Can Be Hard To Stand Up Straight In A Crooked Room:" Examining The Mediating Effects Of Black Women's Gendered Racial Identity On The Relationship Between The Strong Black Woman/Superwoman Schema And Collective Coping, Devin Willis

Dissertations

Prior research on the Strong Black Woman (SBW)/Superwoman (SW) schema has produced mixed findings. Both positive and negative outcomes of Black women’s internalization of this schema have been identified. These mixed findings may be linked to the measurement of the SBW/SW schema and the relationship with other culturally relevant variables. There have been significant positive relationships identified between Black women’s gendered racial identity (GRID) and the internalization of gendered racial stereotypes (i.e., the SBW/SW). Methods for coping with stereotypes have also been identified as influential when considering Black women’s coping behaviors.

The purpose of this study is to examine the …

Cognitive Behavioral Therapy Complemented With Emotion Regulation Training For Patients With Somatic Symptom Disorder: 3-Year Follow-Up To A Randomized Controlled Trial, John Barr

All Graduate Theses and Dissertations, Fall 2023 to Present

This manuscript is a 3-year follow-up analysis of a multicenter, randomized, parallel group, controlled trial (N = 254) employed with individuals struggling with somatic symptom disorder (SSD; Kleinstäuber et al., 2019) comparing the effects of cognitive behavioral therapy (CBT) alone and enriching cognitive behavioral therapy with emotion regulation training (ENCERT). Results from Kleinstäuber et al. (2019) suggested that both of these interventions were similarly efficacious for SSD for symptom severity (primary outcome), with moderate to large effects at post treatment and 6-month follow-up. Further analysis of secondary outcomes and moderation effects demonstrated results suggesting ENCERT was superior to CBT-SOMA …

Exploring The Long-Term Impact Of Dating And Family Violence On American Indian Youth And Adults: The Role Of Belongingness In Moderating Negative Effects, Racheal M. Killgore

All Graduate Theses and Dissertations, Fall 2023 to Present

Exposure to violence during childhood and adolescence is an important issue, particularly among Native Americans, who experience violence at higher rates compared to other racial/ethnic groups. This early exposure to violence can significantly affect future physical and mental health outcomes—including depression, substance abuse, suicide attempts, obesity, and premature death—while also shaping subsequent relationships in adulthood. Though widely studied in the general population, research focused on American Indians is lacking, with cultural contexts and factors uniquely shaping the experiences of those affected. In AI/AN communities, belongingness is important for well-being and, as such, is a relevant cultural factor that calls for …

Protecting The Dreams Of Indigenous Psychology Trainees: Stories Of Culturally Competent Supervision, Erica Ficklin

All Graduate Theses and Dissertations, Fall 2023 to Present

Supervision is the process through which current psychologists pass on important lessons about providing clinical services to the community. Through supervision, psychology trainees learn how to make therapy beneficial to as many people as possible, how to balance their work as therapists with their personal lives, and how to continue learning new skills throughout their careers. Because supervision is vitally important to the field of psychology and future psychologists, it is important that supervision support trainees from all cultural backgrounds. Currently, little research exists on culturally congruent supervision for Indigenous psychology trainees. This study aimed to add to the literature …
