Item A critical review of front-loading: A maladaptive drinking pattern driven by alcohol's rewarding effects(Wiley, 2022) Ardinger, Cherish E.; Lapish, Christopher C.; Czachowski, Cristine L.; Grahame, Nicholas J.; Psychology, School of ScienceFront‐loading is a drinking pattern in which alcohol intake is skewed toward the onset of reward access. This phenomenon has been reported across several different alcohol self‐administration protocols in a wide variety of species, including humans. The hypothesis of the current review is that front‐loading emerges in response to the rewarding effects of alcohol and can be used to measure the motivation to consume alcohol. Alternative or additional hypotheses that we consider and contrast with the main hypothesis are that: (1) front‐loading is directed at overcoming behavioral and/or metabolic tolerance and (2) front‐loading is driven by negative reinforcement. Evidence for each of these explanations is reviewed. We also consider how front‐loading has been evaluated statistically in previous research and make recommendations for defining this intake pattern in future studies. Because front‐loading may predict long‐term maladaptive alcohol drinking patterns leading to the development of alcohol use disorder (AUD), several future directions are proposed to elucidate the relationship between front‐loading and AUD.Item A Global Survey on Changes in the Supply, Price, and Use of Illicit Drugs and Alcohol, and Related Complications During the 2020 COVID-19 Pandemic(Frontiers Media, 2021-08-06) Farhoudian, Ali; Radfar, Seyed Ramin; Ardabili, Hossein Mohaddes; Rafei, Parnian; Ebrahimi, Mohsen; Zonoozi, Arash Khojasteh; De Jong, Cornelis A. J.; Vahidi, Mehrnoosh; Yunesian, Masud; Kouimtsidis, Christos; Arunogiri, Shalini; Hansen, Helena; Brady, Kathleen T.; ISAM Global Survey Consortium (ISAM-GSC); Potenza, Marc N.; Baldacchino, Alexander Mario; Ekhtiari, Hamed; Psychology, School of ScienceBackground and Aims: COVID-19 has infected more than 77 million people worldwide and impacted the lives of many more, with a particularly devastating impact on vulnerable populations, including people with substance use disorders (SUDs). Quarantines, travel bans, regulatory changes, social distancing, and “lockdown” measures have affected drug and alcohol supply chains and subsequently their availability, price, and use patterns, with possible downstream effects on presentations of SUDs and demand for treatment. Given the lack of multicentric epidemiologic studies, we conducted a rapid global survey within the International Society of Addiction Medicine (ISAM) network in order to understand the status of substance-use patterns during the current pandemic. Design: Cross-sectional survey. Setting: Worldwide. Participants: Starting on April 4, 2020 during a 5-week period, the survey received 185 responses from 77 countries. Measurements: To assess addiction medicine professionals' perceived changes in drug and alcohol supply, price, use pattern, and related complications during the COVID-19 pandemic. Findings: Participants reported (among who answered “decreased” or “increased”) a decrease in drug supply (69.0%) and at the same time an increase in price (95.3%) globally. With respect to changes in use patterns, an increase in alcohol (71.7%), cannabis (63.0%), prescription opioids (70.9%), and sedative/hypnotics (84.6%) use was reported, while the use of amphetamines (59.7%), cocaine (67.5%), and opiates (58.2%) was reported to decrease overall. Conclusions: The global report on changes in the availability, use patterns, and complications of alcohol and drugs during the COVID-19 pandemic should be considered in making new policies and in developing mitigating measures and guidelines during the current pandemic (and probable future ones) in order to minimize risks to people with SUD.Item A meta-analytic review of the effectiveness of mood inductions in eliciting emotion-based behavioral risk-taking and craving in the laboratory(American Psychological Association, 2023) Um, Miji; Revilla, Rebecca; Cyders, Melissa A.; Psychology, School of ScienceUrgency research supports the role of emotions in risk-taking and craving. However, much of this work is based in self-report. It is not yet known whether existing experimental methods can effectively induce emotion-based risk-taking and craving. The present meta-analysis quantified the effectiveness of mood inductions in inducing risk-taking and craving in the laboratory. We also examined potential moderators, including participant factors, changes in emotional arousal, and study design factors. For negative mood inductions, the degree of changes in risk-taking (k = 35, Hedge’s g (SE) = 0.12 (0.04), 95% CI [0.04 – 0.21]) and craving (k = 37, Hedge’s g (SE) = 0.30 (0.06), 95% CI [0.19 – 0.40]) were small. Increases in emotional arousal were significantly related to increases in craving (B* = 0.26). For positive mood inductions, there was no significant change in risk-taking (k = 18, Hedge’s g (SE) = 0.17 (0.11), 95% CI [−0.04 – 0.38]) nor craving (k = 8, Hedge’s g (SE) = −0.10 (0.10), 95% CI [−0.31 – 0.10]); however, false positive feedback produced the largest increase in risk-taking. Study samples using guided imagery produced a moderate decrease in risk-taking. Overall, existing negative mood inductions increased risk-taking and craving in the laboratory to a small degree. Existing positive mood inductions failed to elicit risk-taking or craving, although the literature in this domain was sparser. We suggest that there is a great need to develop and optimize mood induction methods to better study emotion-based risk-taking and craving in the laboratory.Item A Pilot Randomized Controlled Trial Investigating MBSR for Parkinson’s Disease Patients and Their Caregiving Partners: Effects on Distress, Social support, Cortisol, and Inflammation(Springer, 2022) Siwik, Chelsea J.; Phillips, Kala; Litvan, Irene; Salmon, Paul; Rodgers, Allison; Jablonski, Megan; Sephton, Sandra E.; Psychology, School of ScienceObjectives: To examine the preliminary effects of the mindfulness-based stress reduction (MBSR) program in the management of biopsychosocial stress–related changes associated with Parkinson’s disease (PD) among patient/caregiving-partner dyads. Methods: PD patient/caregiving-partner dyads (N = 18) early in the disease trajectory were recruited from a university-affiliated movement disorders clinic and were randomized (1:1) to either the MBSR intervention or the control condition (treatment as usual [TAU]). Mixed methods ANOVAs were conducted to examine primary outcomes (disease-specific distress, perceived social support, circadian rhythmicity [cortisol], and markers of inflammation [IL-6, TNF-alpha, IL-1beta]) between groups (MBSR vs. TAU) among patients and caregiving partners separately. Results: No participants were lost to follow-up. Given the pilot nature of the current investigation, findings should be interpreted as exploratory opposed to confirmatory. Following MBSR, PD patients reported an increase in disease-specific distress and intrusive thoughts and demonstrated a decrease in mean bedtime cortisol and IL-1beta from baseline to follow-up compared to TAU. Caregiving partners who received MBSR reported an increase in perceived social support and demonstrated improved rhythmicity of diurnal cortisol slopes from baseline to follow-up compared to TAU. Conclusions: Both patients and caregiving partners who received MBSR demonstrated improvements in biomarkers of circadian function, and patients evidenced a decrease in a biomarker of systemic inflammation, pointing to an important area of further investigation. Given that patients reported an increase in disease-specific distress and intrusive thoughts, the salutary effects of MBSR may be experienced physiologically prior to, or in lieu of, psychological effects, although this should be explored further, especially given the improvement in perceived social support reported by caregiving partners.Item A Systematic Approach to Developing Virtual Patient Vignettes for Pediatric Health Equity Research(Mary Ann Liebert, 2022-11-22) Mulchan, Siddika S.; Miller, Megan; Theriault, Christopher B.; Zempsky, William T.; Hirsh, Adam; Psychology, School of ScienceObjective: The aim of this study was to describe a systematic approach to developing virtual patient (VP) vignettes for health equity research in pediatric pain care. Methods: VPs were initially developed to depict the body posture and movements of actual children experiencing pain. Researchers and clinicians with expertise in pediatric pain worked closely with a professional animator to portray empirically supported pain expression in four, full-motion, virtual male characters of two races (i.e., White and Black). Through an iterative process, VPs were refined to (1) appear realistic in a clinical setting and (2) display archetypal pain behavior and expression during a 1-min video clip without sound. Text vignettes were developed with consultation from experts in pain care and presented alongside VPs to assess clinical decision-making. VP vignettes were piloted in a sample of pediatric providers (N=13). Results: Informed by the literature and expertise of stakeholders, several revisions were made to improve VPs' facial grimacing and realism before piloting. VPs appeared to accurately capture important aspects of pain expression and behavior common among pediatric patients with pain disorders. Additional refinements to the text vignettes were made based on provider feedback to improve clarity and clinical relevance. Conclusions: This article presents a working framework to facilitate a systematic approach to developing VP vignettes. This framework is a first step toward advancing health equity research by isolating psychosocial and interpersonal factors affecting provider behavior and decision-making. Future research is needed to validate the use of VP vignettes for assessing provider behavior contributing to health inequities for youth with pain disorders.Item Acceptance and commitment therapy for fatigue interference in advanced gastrointestinal cancer and caregiver burden: protocol of a pilot randomized controlled trial(BMC, 2021-04-20) Mosher, Catherine E.; Secinti, Ekin; Kroenke, Kurt; Helft, Paul R.; Turk, Anita A.; Loehrer, Patrick J., Sr.; Sehdev, Amikar; Al-Hader, Ahmad A.; Champion, Victoria L.; Johns, Shelley A.; Psychology, School of ScienceBackground: Fatigue interference with activities, mood, and cognition is one of the most prevalent and bothersome concerns of advanced gastrointestinal (GI) cancer patients. As fatigue interferes with patient functioning, family caregivers often report feeling burdened by increasing responsibilities. Evidence-based interventions jointly addressing cancer patient fatigue interference and caregiver burden are lacking. In pilot studies, acceptance and commitment therapy (ACT) has shown promise for addressing symptom-related suffering in cancer patients. The current pilot trial seeks to test a novel, dyadic ACT intervention for both advanced GI cancer patients with moderate-to-severe fatigue interference and their family caregivers with significant caregiving burden or distress. Methods: A minimum of 40 patient-caregiver dyads will be randomly assigned to either the ACT intervention or an education/support control condition. Dyads in both conditions attend six weekly 50-min telephone sessions. Outcomes are assessed at baseline as well as 2 weeks and 3 months post-intervention. We will evaluate the feasibility, acceptability, and preliminary efficacy of ACT for improving patient fatigue interference and caregiver burden. Secondary outcomes include patient sleep interference and patient and caregiver engagement in daily activities, psychological flexibility, and quality of life. We will also explore the effects of ACT on patient and caregiver physical and mental health service use. Discussion: Findings will inform a large-scale trial of intervention efficacy. Results will also lay the groundwork for further novel applications of ACT to symptom interference with functioning and caregiver burden in advanced cancer.Item Acceptance and commitment therapy for patient fatigue interference and caregiver burden in advanced gastrointestinal cancer: Results of a pilot randomized trial(Sage, 2022) Mosher, Catherine E.; Secinti, Ekin; Wu, Wei; Kashy, Deborah A.; Kroenke, Kurt; Bricker, Jonathan B.; Helft, Paul R.; Turk, Anita A.; Loehrer, Patrick J., Sr.; Sehdev, Amikar; Al-Hader, Ahmad A.; Champion, Victoria L.; Johns, Shelley A.; Psychology, School of ScienceBackground: Fatigue often interferes with functioning in patients with advanced cancer, resulting in increased family caregiver burden. Acceptance and commitment therapy, a promising intervention for cancer-related suffering, has rarely been applied to dyads coping with advanced cancer. Aim: To examine the feasibility, acceptability, and preliminary efficacy of acceptance and commitment therapy for patient-caregiver dyads coping with advanced gastrointestinal cancer. Primary outcomes were patient fatigue interference and caregiver burden. Design: In this pilot trial, dyads were randomized to six weekly sessions of telephone-delivered acceptance and commitment therapy or education/support, an attention control. Outcomes were assessed at baseline and at 2 weeks and 3 months post-intervention. Setting/participants: Forty patients with stage III-IV gastrointestinal cancer and fatigue interference and family caregivers with burden or distress were recruited from two oncology clinics and randomized. Results: The eligibility screening rate (54%) and retention rate (81% at 2 weeks post-intervention) demonstrated feasibility. At 2 weeks post-intervention, acceptance and commitment therapy participants reported high intervention helpfulness (mean=4.25/5.00). Group differences in outcomes were not statistically significant. However, when examining within-group change, acceptance and commitment therapy patients showed moderate decline in fatigue interference at both follow-ups, whereas education/support patients did not show improvement at either follow-up. Acceptance and commitment therapy caregivers showed medium decline in burden at 2 weeks that was not sustained at 3 months, whereas education/support caregivers showed little change in burden. Conclusions: Acceptance and commitment therapy showed strong feasibility, acceptability, and promise and warrants further testing.Item Acceptance and Commitment Therapy for Symptom Interference in Advanced Lung Cancer and Caregiver Distress: A Pilot Randomized Trial(Elsevier, 2019) Mosher, Catherine E.; Secinti, Ekin; Hirsh, Adam T.; Hanna, Nasser; Einhorn, Lawrence H.; Jalal, Shadia I.; Durm, Gregory; Champion, Victoria L.; Johns, Shelley A.; Psychology, School of ScienceContext Advanced lung cancer patients typically have a poor prognosis and many symptoms that interfere with functioning, contributing to high rates of emotional distress in both patients and family caregivers. There remains a need for evidence-based interventions to improve functional outcomes and distress in this population. Objectives This pilot trial examined the feasibility and preliminary efficacy of telephone-based Acceptance and Commitment Therapy (ACT) for symptomatic, advanced lung cancer patients and their distressed family caregivers. Primary outcomes were patient symptom interference with functioning and patient and caregiver distress. Methods Symptomatic, advanced lung cancer patients and distressed caregivers (n = 50 dyads) were randomly assigned to six sessions of ACT or an education/support condition. Patients completed measures of symptom interference and measures assessing the severity of fatigue, pain, sleep disturbance, and breathlessness. Patients and caregivers completed measures of distress and illness acceptance and struggle. Results The eligibility screening rate (51%) and retention rate (76% at six weeks postintervention) demonstrated feasibility. No group differences were found with respect to patient and caregiver outcomes. Both groups showed a small, significant decrease in struggle with the illness over the study period, but did not show meaningful change in other outcomes. Conclusion Findings suggest that telephone-based ACT is feasible for many advanced lung cancer patients and caregivers, but may not substantially reduce symptom interference and distress. Low baseline levels of certain symptoms may have contributed to null findings. Next steps include applying ACT to specific, clinically meaningful symptom interference and varying intervention dose and modality.Item Acceptance and commitment therapy for symptom interference in metastatic breast cancer patients: a pilot randomized trial(Springer Nature, 2018-06) Mosher, Catherine E.; Secinti, Ekin; Li, Ruohong; Hirsh, Adam T.; Bricker, Jonathan; Miller, Kathy D.; Schneider, Bryan; Storniolo, Anna Maria; Mina, Lida; Newton, Erin V.; Champion, Victoria L.; Johns, Shelley A.; Psychology, School of SciencePURPOSE: Breast cancer is the leading cause of cancer mortality in women worldwide. With medical advances, metastatic breast cancer (MBC) patients often live for years with many symptoms that interfere with activities. However, there is a paucity of efficacious interventions to address symptom-related suffering and functional interference. Thus, this study examined the feasibility and preliminary efficacy of telephone-based acceptance and commitment therapy (ACT) for symptom interference with functioning in MBC patients. METHODS: Symptomatic MBC patients (N = 47) were randomly assigned to six telephone sessions of ACT or six telephone sessions of education/support. Patients completed measures of symptom interference and measures assessing the severity of pain, fatigue, sleep disturbance, depressive symptoms, and anxiety. RESULTS: The eligibility screening rate (64%) and high retention (83% at 8 weeks post-baseline) demonstrated feasibility. When examining within-group change, ACT participants showed decreases in symptom interference (i.e., fatigue interference and sleep-related impairment; Cohen's d range = - 0.23 to - 0.31) at 8 and 12 weeks post-baseline, whereas education/support participants showed minimal change in these outcomes (d range = - 0.03 to 0.07). Additionally, at 12 weeks post-baseline, ACT participants showed moderate decreases in fatigue and sleep disturbance (both ds = - 0.43), whereas education/support participants showed small decreases in these outcomes (ds = - 0.24 and - 0.18 for fatigue and sleep disturbance, respectively). Both the ACT and education/support groups showed reductions in depressive symptoms (ds = - 0.27 and - 0.28) at 12 weeks post-baseline. Group differences in all outcomes were not statistically significant. CONCLUSIONS: ACT shows feasibility and promise in improving fatigue and sleep-related outcomes in MBC patients and warrants further investigation.Item Accuracy of Electronic Health Record Food Insecurity, Housing Instability, and Financial Strain Screening in Adult Primary Care(American Medical Association, 2023) Harle, Christopher A.; Wu, Wei; Vest, Joshua R.; Psychology, School of Science
