RESUMEN

INTRODUCTION: Veterans and active duty service members are significantly more likely to die by suicide using firearms compared to the general population. Not-secure firearm storage (e.g., keeping guns loaded/in an unlocked location) is associated with greater risk for suicide and a third of veteran firearm owners store at least 1 personal firearm unsecured. Veterans and active duty service members are also significantly more likely to be diagnosed with posttraumatic stress disorder (PTSD) than the general population. Symptoms of PTSD are divided into 4 criteria: reexperiencing, avoidance, negative affect, and hyperarousal. Research has suggested that endorsement of hyperarousal symptoms is positively associated with unsecure firearm storage and that avoidance symptoms might be negatively associated with unsecure storage practices. The present study examined the relationship between self-reported firearm ownership and storage practices among each item from the Primary Care PTSD Screening for DSM-IV-TR (PC-PTSD-IV) to explore associations between PTSD features and firearm ownership and storage. MATERIALS AND METHODS: Participants were recruited from primary care clinics across 5 military installations in the United States as part of a larger study (Mage = 45.4, SD = 16.9). Among participants (n = 2,685), most of our sample identified as male (51.3%) and white (67.3%) with 61.6% currently serving in the military, 16.8% retirees, and 21.6% family members. PTSD symptoms were assessed using the PC-PTSD-IV and a quarter met the clinical threshold for PTSD. Binomial and multinomial logistic regression analyses were used. RESULTS: Among completed responses, 989 (38.1%) people reported owning guns; among gun owners, 386 (39.0%) reported that they were loaded, and 352 (35.6%) reported they were loaded and unlocked. Endorsement of specific items on the PC-PTSD-IV, including those specific to hyperarousal and avoidance, was not significantly associated with storing firearms loaded and/or in nonsecure locations when controlling for military service. Non-responses to items around firearm storage practices were significantly associated with those individuals meeting the clinical threshold for PTSD according to the PC-PTSD-IV and participants currently serving had higher odds of storing at least 1 personal firearm loaded and both loaded and unlocked. CONCLUSIONS: Results from our study highlight similarities and departures from the previous literature on the connection between PTSD and non-secure firearm storage practices. Further research may examine (1) the relation between PTSD symptoms and firearm storage between active duty service members, retirees, and family members and (2) whether non-response to items regarding firearm ownership is systematic.

RESUMEN

The Suicide Cognitions Scale-Revised (SCS-R) is a unidimensional measure of suicidal cognitions theorized to assess the suicide belief system. Several solutions have been proposed for the Suicide Cognitions Scale and SCS-R (e.g., bifactor model with two specific factors, bifactor model with two specific factors, three correlated factors model). Research indicates the endorsement of thoughts of suicide and suicide-related cognitions varies across demographics. Thus, the current investigation tested the measurement invariance (MI) of the SCS-R across gender, race, and sexual orientation within these proposed solutions and a unidimensional model. A national sample of N = 10,625 adults completed an online survey that included the SCS-R and self-report measures of demographics. Results indicated that the bifactor model with three specific factors, the bifactor model with two specific factors, and the three correlated factors models achieved scalar invariance across gender, race, and sexual orientation; a unidimensional model was not scalar invariant by gender. Tests of latent mean differences revealed significant differences in the general factor (i.e., suicidal belief system) and the specific unlovability, unbearability, and unsolvability factors between a few demographic groups. Implications for theory, measurement, and modeling are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMEN

Background: Hyperkatifeia describes amplified emotional and motivational withdrawal due to addiction-related sensitization of brain-stress-systems. Hyperkatifeia has been proposed as a target for addiction treatment development. However, translation of basic research in this area will require new tools designed to measure hyperkatifeia and related phenomena outside of laboratory settings.Objectives: We define a novel concept, withdrawal interference, and introduce a new tool - the Withdrawal Interference Scale (WIS) - which measures the impact of withdrawal on daily life among individuals with OUD or AUD.Methods: Described are the combined results of three separate cross-sectional studies. The structural validity, convergent validity, construct validity, trans-diagnostic (AUD/OUD) configural, metric, and scalar invariance, internal consistency, and composite reliability of WIS was tested among three independent samples of 1) treatment-seeking adults with OUD (n = 132), 2) treatment-seeking adults with AUD (n = 123), and 3) non-treatment-seeking adults with OUD (n = 140). Males numbered 218 and females were 163.Results: WIS exhibited structural validity (1 factor), convergent validity (average variance extracted .670-.676), construct validity, trans-diagnostic configural (χ2/df = 2.10), metric (Δχ2 = 5.70, p = .681), and scalar invariance (Δχ2 = 12.34, p = .338), internal consistency (α .882-928), and composite reliability (.924-.925).Conclusion: These results suggest WIS is a valid and reliable instrument for measuring withdrawal-related life disruption in AUD and OUD. Further, given our findings of transdiagnostic measurement invariance, WIS scores of individuals with AUD and OUD can be meaningfully compared in future statistical analyses.

RESUMEN

BACKGROUND: Clinician collaboration can help high-risk individuals to manage their suicidal crises. However, limited research has directly examined how higher patient-clinician collaboration during assessment and intervention can effectively reduce suicidal ideation. This novel randomized clinical trial compared a high vs. low level of patient-clinician collaboration by pairing commonly used assessment (Structured Interview vs. Narrative Assessment) and intervention approaches (Safety Planning Intervention vs. Crisis Response Planning). We hypothesized that the interventions involving higher (than lower) patient-clinician collaboration during assessment (Narrative Assessment) or intervention (Crisis Response Planning) would lead to larger reductions in suicidal ideation. METHODS: Eighty-two participants with a history of suicide ideation and/or attempts were randomly assigned to one of the four interventions varying in patient-clinician collaboration. After attrition, sixty-six participants completed the study. Suicidal ideation via ecological momentary assessment was measured 14 days before and 14 days after treatment. RESULTS: Although the severity of suicidal ideation decreased in all groups, the two groups that included highly collaborative assessment had larger pre-post reductions in suicidal ideation (Narrative Assessment+Safety Plan; dwithin = 0.26, and Narrative Assessment+Crisis Response Plan; dwithin = 0.19) than the groups that included a checklist-based assessment (Structured Interview). LIMITATIONS: Longer follow-up periods with a larger sample would have provided an understanding of the durability of intervention effects. CONCLUSION: Results suggest that the inclusion of higher patient-clinician collaboration techniques during suicide risk assessment can effectively reduce suicidal thoughts. Thus, clinician-led collaborative risk assessment approaches can enhance the effects of safety planning-type interventions among patients with elevated risk for suicide versus checklist-based assessment approaches.

RESUMEN

BACKGROUND: Veteran suicide remains a significant issue, as 17.5 Veterans die by suicide each day. The US Department of Veteran Affairs (VA) has implemented a robust suicide prevention program within its integrated behavioural health system. Further, the VA has increasingly contributed to suicide prevention in community settings, where a large proportion of Veterans receive health care and social services. One component integral to preventing suicide among Veterans receiving community services is ensuring that organisations are equipped with the latest evidence-based Veteran-specific suicide prevention strategies. METHODS: The Patient Safety Center of Inquiry-Suicide Prevention Collaborative piloted a Veteran suicide prevention learning collaborative in the Denver/Colorado Springs, CO region, spanning 16 months as a multimodal initiative to integrate community organisations and assist them in implementing Veteran suicide prevention strategies used within VA. Agencies completed social network analysis surveys at baseline (T1), year 1 (T2) and 16 months (T3) to examine social networks, partnerships and collaborations among community organisations and the VA over time. RESULTS: The quantity of learning collaborative relationships increased from 30 at T1 to 41 at T3 while the quality of relationships deepened over time from awareness and cooperative to more coordinated and integrated. CONCLUSION: Improvement in relationship quantity and quality facilitates community organisation engagement in collaborating to strengthen their Veteran suicide prevention programming. Learning collaboratives work with the individual organisation for intraorganisational facilitation of implementing suicide prevention strategies and engage and enhance interorganisational partnerships. This multimodal intervention can engage community organisations and provide a stronger safety net for Veterans at risk for suicide.

RESUMEN

BACKGROUND: U.S. military veterans may be reluctant to disclose suicidal thoughts and behaviors. Suicide-specific cognitions, which generally avoid direct mention of suicide, may be reliable indicators of risk among those reluctant to disclose such thoughts and behaviors. METHODS: Data from a population-based, cross-sectional study of 2,430 U.S. military veterans were analyzed to examine the associations between the Brief Suicide Cognitions Scale (B-SCS), suicidal ideation, and suicide planning. RESULTS: After adjusting for age, sex, number of adverse childhood experiences, cumulative trauma burden, depressive symptom severity, and lifetime history of suicide attempt, total scores on the B-SCS (excluding the item mentioning suicide) were uniquely associated with suicidal ideation (odds ratio [OR] = 1.23, 95% confidence interval [CI] = 1.15-1.32) and suicide planning (OR = 1.27, 95%CI = 1.18-1.37). Exploratory post-hoc analyses revealed that difficulties with solving and coping with one's problems were uniquely linked to these outcomes. CONCLUSIONS: Assessment of suicide-specific cognitions may help to enhance suicide detection and prevention in veterans, especially in those who may not directly disclose thoughts of suicide. Intervention efforts to bolster perceived deficits in coping and problem-solving may help mitigate suicide risk in this population.

RESUMEN

Neuroendocrine analyses of posttraumatic stress disorder (PTSD) have generally focused on hypothalamic-pituitary-adrenal (HPA) axis alterations. In the present analyses, we examine two additional neuroendocrine factors that have been previously implicated in biological stress responses: oxytocin (OT) and arginine vasopressin (AVP). Here we examined basal neuropeptide status in military veterans clinically diagnosed with PTSD (n = 29) and in two non-traumatized comparison groups with previous stress exposure (n = 11 SWAT trainees and n = 21 ultramarathon runners). PTSD patients showed low levels of plasma OT and high levels of AVP. The ratio of AVP/OT robustly related to PTSD status, and emerged as a statistically plausible mediator of relationships between the number of personal traumatic experiences and subsequent PTSD symptom burden. Over the course of behavioral therapy for PTSD, measures of OT showed a significant but modest normalization. Plasma cortisol levels were not statistically different among the three groups. This study suggests that AVP/OT ratios may represent a neuroendocrine predictor of severe PTSD, as well as a potential treatment response biomarker.

RESUMEN

OBJECTIVE: Suicide is a significant public health concern. About 48,000 individuals died by suicide in 2021 in the United States, and approximately one in 100 deaths globally are due to suicide. Continuing efforts in program development and evaluation are vital to preventing suicide. Multiple frameworks have been developed to reduce suicide rates, but they have not been compared to assess their comprehensiveness, nor have their components been classified. METHODS: In 2019, the authors conducted a narrative review of the literature and identified four major frameworks for suicide prevention: the U.S. Department of Veterans Affairs (VA) Suicide Prevention Program, the Defense Suicide Prevention Program of the U.S. Department of Defense, Zero Suicide in Health and Behavioral Health Care, and the technical package developed by the Centers for Disease Control and Prevention. Program components for these frameworks were identified and classified by using two prevention strategy classification systems: the National Academy of Medicine's (NAM's) continuum-of-care model and the Substance Abuse and Mental Health Services Administration's (SAMHSA's) prevention model. RESULTS: The cross-program comparison revealed that no single program included all components of suicide prevention programs. However, the VA program was the most comprehensive in terms of the number of components and their spread across prevention strategy classifications. The programs used few components categorized under NAM's promotion or selective prevention strategy classifications. The SAMHSA prevention strategy classifications of information dissemination, community-based processes, and positive alternatives were also used infrequently. CONCLUSIONS: Organizations, health care systems, and policy makers may use these findings as they develop, improve, and implement suicide prevention programs.

RESUMEN

Recent studies have suggested that owning a firearm for the purpose of protection and intending to acquire a firearm within the next year are associated with disrupted cognitive-affective processes that may increase firearm suicide risk. Prior studies were limited by self-report measures and would benefit from the utilization of objective indicators of cognitive functioning to clarify associations between firearm ownership and cognitive-affective states. The present study examined objective cognitive performance in a sample of U.S. adults in relation to firearm ownership variables. Based on prior studies, we hypothesized that protective owners and individuals with the intention to acquire a firearm within the next year would demonstrate reduced performance on decision-making, mental flexibility, and emotional bias tasks. A total of 112 participants (61% female, 79% white) completed objective cognitive tasks following completion of a larger survey study through ResearchMatch. Results indicated that intention to purchase a firearm within the next year was not associated with cognitive functioning but was associated with an array of heightened psychiatric symptoms. Owning a firearm for the purpose of protection was associated with decreased mental flexibility relative to non-owners, but no differences were seen for decision-making or emotional bias. These findings represent the first attempt to examine underlying objective cognitive processes related to firearm ownership, and implications for future research are discussed.

RESUMEN

Background: Discovery of modifiable factors influencing subjective withdrawal experience might advance opioid use disorder (OUD) research and precision treatment. This study explores one factor - withdrawal catastrophizing - a negative cognitive and emotional orientation toward withdrawal characterized by excessive fear, worry or inability to divert attention from withdrawal symptoms.Objectives: We define a novel concept - withdrawal catastrophizing - and present an initial evaluation of the Withdrawal Catastrophizing Scale (WCS).Methods: Prospective observational study (n = 122, 48.7% women). Factor structure (exploratory factor analysis) and internal consistency (Cronbach's α) were assessed. Predictive validity was tested via correlation between WCS and next-day subjective opiate withdrawal scale (SOWS) severity. The clinical salience of WCS was evaluated by correlation between WCS and withdrawal-motivated behaviors including risk taking, OUD maintenance, OUD treatment delay, history of leaving the hospital against medical advice and buprenorphine-precipitated withdrawal.Results: WCS was found to have a two-factor structure (distortion and despair), strong internal consistency (α = .901), and predictive validity - Greater withdrawal catastrophizing was associated with next-day SOWS (rs (99) = 0.237, p = .017). Withdrawal catastrophizing was also correlated with risk-taking behavior to relieve withdrawal (rs (119) = 0.357, p < .001); withdrawal-motivated OUD treatment avoidance (rs (119) = 0.421, p < .001), history of leaving the hospital against medical advice (rs (119) = 0.373, p < .001) and buprenorphine-precipitated withdrawal (rs (119) = 0.369, p < .001).Conclusion: This study provides first evidence of withdrawal catastrophizing as a clinically important phenomenon with implications for the future study and treatment of OUD.

RESUMEN

OBJECTIVES: To examine rankings of credible sources for discussing secure storage within a representative sample of firearm-owning service members, and examine how combinations of demographic variables impact the ranking of credible sources. METHODS: The probability-based sample was collected with the help of Ipsos. Participants were US service members who owned a firearm at the time of the survey (n = 719). RESULTS: The total sample ranked service members, Veterans, and members of law enforcement as the most credible sources and faith leaders, casual acquittances, and celebrities as the least credible sources. Black men ranked the NRA as a highly credible source whereas Black females ranked the NRA as one of the least preferred sources. Regardless of political preference, those who lived in non-metropolitan rural environments ranked members of law enforcement as highly credible sources. Those who lived in non-metropolitan rural and urban settings and identified as liberal ranked the National Shooting Sports Foundation as a highly credible source. CONCLUSIONS: Law enforcement officers, military members, and Veterans are ranked as highly credible sources by most subgroups of firearm-owning service members. Leveraging these voices in firearm safety conversations is necessary, may increase adherence to secure storage recommendations, and ultimately reduce suicide.

RESUMEN

OBJECTIVE: The present study seeks to add to the existing literature by determining if having a plan for suicide, is associated with an individual's self-reported likelihood of attempting suicide in the future. METHOD: Data came from a sample of 97 United States Army personnel with past week ideation or lifetime attempt history. Assessments were collected at baseline, 1-month, 3-month, and 6-months. RESULTS: Self-reported likelihood of attempting suicide in the future was not associated with the presence of a plan for suicide overall or a plan with a specific method (i.e., firearm, cutting/scratching, and medication). DISCUSSION: Although a plan for suicide is commonly thought to indicate elevated risk our findings suggest that presence or absence of suicide plans is not associated with more self-reported likelihood of a future suicide attempt.


The self-reported likelihood of attempting suicide in the future was not associated with the presence of a plan for suicide among service members.Findings suggest that presence or absence of suicide plans is not associated with self-reported likelihood of suicidal behavior among service members.Clinicians and researchers working with a military population may benefit from a broader approach to risk assessment and safety planning that does not rely too heavily on an individual's self-reported plans for suicide.

RESUMEN

INTRODUCTION: The US Department of Defense recommends lethal means safety counseling (LMSC) to promote firearm injury prevention via secure storage of personal firearms. We describe the rollout of a universal, peer-delivered adaptation of Project Safe Guard (PSG)-a brief, single-session LMSC discussion-at a US Space Force installation. METHOD: Program evaluation data were collected via anonymous, voluntary, and online surveys. Of approximately 862 eligible active-duty service members and embedded civilians, 324 completed the preprogram survey and 68 and 37 completed the 1- and 2-month follow-ups, respectively. RESULTS: At preprogram, 69.1% agreed that peer-delivered LMSC is appropriate. After rollout, 100% of the 222 firearm locking devices available to service members were requested from the on-base Violence Prevention Integrator. The effectiveness of PSG was indeterminable due to the low survey response rates. CONCLUSIONS: Despite strong preprogram support for peer-delivered LMSC and behavioral indicators of secure firearm storage (e.g., firearm locking device requests), several challenges limited the uptake and evaluability of the PSG program in this naturalistic environment, including military survey fatigue and competing mission priorities. Additional work is needed to determine the effectiveness of peer-delivered LMSC in a military context. Sustained base support and military-civilian collaborations will be critical.

RESUMEN

BACKGROUND: Suicide, especially by firearm, remains a leading cause of death in military populations in the USA. Reducing access to firearms, especially during high risk times, may help prevent suicide and other forms of violence. The purpose of this study was to adapt a promising existing lethal means safety intervention (Project Safe Guard, PSG) for cross-cutting violence prevention and peer support in active-duty service communities using community engagement methods. METHODS: A two-pronged community-engaged research approach was employed, including the Community Translation (CT) process that engaged 15 Service Members from one installation to help adapt PSG successfully. In addition, qualitative data was collected from 40 active-duty service members and military violence prevention specialists through in-depth interviews and focus group discussions. RESULTS: Qualitative data and CT feedback led to site-specific PSG adaptations. Participants emphasized the importance of peer-to-peer discussions and highlighted resource allocation, leadership support, and stigma on firearm ownership as potential implementation challenges. CONCLUSIONS: Findings demonstrate the feasibility of community-engaged research to adapt lethal means safety interventions within military populations. PSG implementation should consider resource allocation, leadership support, and addressing stigma. This study has implications for future policies and standards for performing research on sensitive topics, particularly among military populations.

RESUMEN

According to SAMHSA (2023), approximately 16,600,000 American adults and teens reported having serious thoughts of suicide in 2022. While suicide prevention has primarily focused on suicide deaths and attempts, we contend that suicidal ideation (SI) deserves more in-depth investigation and should be an essential intervention target on its own. In support of this point, we provide three examples of ways to improve specificity in understanding of SI through the study of controllability of SI, the language used to assess SI, and measuring SI in real time. We also consider qualitative work on the content of SI, its treatment, and definitional considerations. We thus call for an increased general focus on SI within research, clinical care, and policy.

RESUMEN

OBJECTIVE: The connections among posttraumatic stress disorder (PTSD), depression, and suicidal ideation are elusive because of an overreliance on cross-sectional studies. In this secondary analysis of pooled data from three clinical trials of 742 military personnel, we examined the dynamic relationships among PTSD, depression, and suicidal ideation severity assessed repeatedly during and after outpatient treatment for PTSD. METHODS: We conducted dynamical systems analyses to explore the potential for coordinated change over time in psychotherapy for PTSD. RESULTS: Over the course of psychotherapy, PTSD, depression, and suicidal ideation severity changed in coordinated ways, consistent with an interdependent network. Results of eigenvalue decomposition analysis indicated the dominant change dynamic involved high stability and resistance to change but indicators of cycling were also observed, indicating participants "switched" between states that resisted change and states that promoted change. Depression (B = 0.48, SE = 0.11) and suicidal desire (B = 0.15, SE = 0.01) at a given assessment were associated with greater change in PTSD symptom severity at the next assessment. Suicidal desire (B = 0.001, SE < 0.001) at a given assessment was associated with greater change in depression symptom severity at the next assessment. Neither PTSD (B = -0.004, SE = 0.007) nor depression symptom severity (B = 0.000, SE = 0.001) was associated with subsequent change in suicidal ideation severity. CONCLUSIONS: In a sample of treatment-seeking military personnel with PTSD, change in suicidal ideation and depression may precede change in PTSD symptoms but change in suicidal ideation was not preceded by change in PTSD or depression symptoms.

RESUMEN

BACKGROUND: Suicide is theorized to be connected to social interactions and feelings of belongingness. Those with suicide-related cognitions (SRCs) demonstrate attentional bias toward negative or suicide-related words, which can lead to increased feelings of rejection or alienation. As social interactions employ both verbal and nonverbal cues, there exists a gap in understanding how perception of emotional expressions can contribute to the development or exacerbation of suicidal ideation. METHODS: The current sample (N = 114, 60.5 % female, 74.6 % white) completed the Suicide Cognitions Scale-Revised (SCS-R) and Patient Health Questionnaire (PHQ-9) to assess SRCs and depression severity. The Emotional Bias Task (EBT) was used to assess emotional response latency. RESULTS: Multiple regression analyses on EBT results showed that endorsement of SRCs and depression severity were not associated with any particular emotional response bias. However, presence of SRCs showed an association with longer latencies to identify ambiguous emotional expressions, even when controlling for depressive symptoms and age LIMITATIONS: Measures were self-completed online. Relative homogeneity of the sample and cross-sectional design limits interpretation of the results. CONCLUSIONS: Those with more severe SRCs take longer to recognize positive, nonverbal cues. Irregular processing of positive emotional stimuli combined with bias toward negative verbal cues could worsen feelings of rejection or alienation in social interactions, therefore increasing risk of developing SI. This suggests that interventions focusing on allocation of attentional resources to process positive social cues may be beneficial for those with SRCs to reduce severity and risk of suicide.

RESUMEN

SLK controls the cytoskeleton, cell adhesion, and migration. Podocyte-specific deletion of SLK in mice leads to podocyte injury as mice age and exacerbates injury in experimental focal segment glomerulosclerosis (FSGS; adriamycin nephrosis). We hypothesized that adhesion proteins may be substrates of SLK. In adriamycin nephrosis, podocyte ultrastructural injury was exaggerated by SLK deletion. Analysis of a protein kinase phosphorylation site dataset showed that podocyte adhesion proteins-paxillin, vinculin, and talin-1 may be potential SLK substrates. In cultured podocytes, deletion of SLK increased adhesion to collagen. Analysis of paxillin, vinculin, and talin-1 showed that SLK deletion reduced focal adhesion complexes (FACs) containing these proteins mainly in adriamycin-induced injury; there was no change in FAC turnover (focal adhesion kinase Y397 phosphorylation). In podocytes, paxillin S250 showed basal phosphorylation that was slightly enhanced by SLK; however, SLK did not phosphorylate talin-1. In adriamycin nephrosis, SLK deletion did not alter glomerular expression/localization of talin-1 and vinculin, but increased focal adhesion kinase phosphorylation modestly. Therefore, SLK decreases podocyte adhesion, but FAC proteins in podocytes are not major substrates of SLK in health and disease.

RESUMEN

Posttraumatic stress disorder (PTSD) is associated with suicidal thoughts and behaviours. Decision-making processes and risk-taking are prominent for coping in both, but the implications for guaranteed and probabilistic reward discounting, important components in behavioural decision-making processes, are unclear. This study explored the relationships between PTSD and suicide risk with tendencies towards devaluing guaranteed rewards that are larger but delayed (i.e., delay discounting; DD) and devaluing larger but uncertain rewards (i.e., probability discounting; PD) for immediate but smaller rewards. The current study evaluated 498 participants (majority male [51.4%] and white [63.8%]; 33.3% screening positive for probable PTSD; 19.2% with lifetime suicide attempts; 30.8% with recent suicide ideation) on both delayed discounting and PD tasks. Provisional PTSD diagnosis, but not suicide attempts or ideation, was associated with increased PD (i.e., more devaluation of uncertain rewards). Conversely, PTSD interacted with both attempt history and ideation to predict increased delayed discounting (i.e., more devaluing of greater but delayed rewards). These results highlight how those with PTSD symptoms assign valuations to rewards, as well as how the addition of suicide risk interacts to impact these decision-making processes. While further research is needed, this suggests potential implications for treatment as they may benefit from structuring progress in smaller, more immediate goals.

RESUMEN

Heavy chronic alcohol use may produce pain amplification through neurochemical and neuroplastic changes at multiple levels of the nervous system. Similar changes are thought to underlie nociplastic pain. The American College of Rheumatology Fibromyalgia Survey has been used as a surrogate for nociplastic pain, including among individuals with alcohol use disorder (AUD). However, studies linking nociplastic pain to pain-motivated drinking are lacking. The present study aimed to determine if nociplastic pain is associated with pain-motivated drinking in AUD. To achieve this aim, a new scale-the Pain-Motivated Drinking Scale (PMDS)-was developed to measure how often participants were motivated by pain to drink alcohol. Measurement properties of this new scale were determined, including its factor structure, internal consistency reliability, and construct validity. In this cross-sectional observational study, participants with AUD (n = 138) were consecutively recruited from the patient pool at an academic addiction treatment facility. Seventy-two percent (95, 72.0%) reported they drank alcohol "to get relief from physical pain" at least some of the time, and over forty-two percent (56, 42.4%) reported pain relief motivated their drinking at least half of the time. PMDS had a single-factor structure, strong internal consistency reliability, and construct validity. A multiple hierarchical linear regression was run to determine if nociplastic pain was associated with pain-motivated drinking. Nociplastic pain was associated with PMDS even after controlling for potential confounders and pain severity. These findings suggest nociplastic pain is uniquely associated with pain-motivated drinking in AUD. PERSPECTIVE: Nociplastic pain is independently associated with pain-motivated drinking in alcohol use disorder (AUD). The Pain-Motivated Drinking Scale (PMDS) is a new scale to measure how often people drink to cope with pain. PMDS has promising psychometric properties. Nociplastic pain may be uniquely associated with pain-motivated drinking in AUD.
