RESUMO

Problematic alcohol use is a serious threat to the behavioral health of active-duty Service Members (ADSM), resulting in numerous calls from governmental agencies to better understand mechanistic factors contributing to alcohol misuse within the military. Alcohol use motives are reliable predictors of alcohol-related behaviors and are considered malleable targets for prevention and intervention efforts. However, empirical research indicates that drinking motives vary across contextually distinct populations. Although some research has been conducted among veteran and reservist populations, limited work has been specifically focused on ADSM and no research has evaluated motives and alcohol metrics among ADSM based on military rank. Participants for the current study included 682 ADSM recruited from a large military installation in the U.S. Structural equation modeling evaluated associations between four drinking motives (i.e., enhancement, social, conformity, coping) and three alcohol misuse metrics (i.e., alcohol frequency, binge frequency, alcohol problems). Three models were evaluated: one full (combined) model and two separate models based on military rank - junior enlisted (i.e., E1-E4) and non-commissioned officers (NCOs) (i.e., E5-E9). Results for junior enlisted ADSM indicated that coping and enhancement motives were most strongly associated with all alcohol misuse metrics. However, among NCOs, results indicated that alcohol problems were only associated with coping motives. Notably, results also indicated that alcohol use motives accounted for substantively more variance across all alcohol-related metrics among NCOs. Findings generally support extant military-related literature indicating use of alcohol for coping (e.g., with anxiety) as the motivation most consistently associated with increased alcohol misuse. However, novel findings highlight enhancement motives - using alcohol to attain some positive internal reward - as another, often stronger, motivation impacting alcohol use outcomes. Further, findings highlight notable distinctions between alcohol use motives (i.e., coping vs. enhancement) and the impact of alcohol use motives (i.e., effect size) on alcohol metrics between junior enlisted and NCOs.

RESUMO

Subjective well-being is a positive psychological construct that has important implications for the U.S. Military's goal to develop service members' strengths and support their overall thriving and downstream resilience. Despite this, the concept of well-being has not been well studied in military populations who have unique work demands, stressors, and autonomy/agency in daily life compared to civilians. To address this shortcoming in the literature, the present study assessed Ryff's measures of psychological well-being (PWB) in 1,333 U.S. service members prior to the deployments in the Middle East. Various methods attempting to validate the theoretical model purported by Ryff were unsuccessful, and exploratory factor analyses did not result in a novel model for this population. Future research should continue to evaluate proposed models of soldier well-being and propose novel theories, as well as measures, to assess this important construct. Implications are discussed.

RESUMO

Prior theory and research suggest that both Cluster-B personality pathology and trait impulsivity are indirectly associated with alcohol use through positive alcohol expectancies. Yet, no prior study has investigated whether features of each of the Cluster-B personality disorders (PDs) (i.e., antisocial, borderline, histrionic, and narcissistic) and rash impulsiveness are indirectly associated with alcohol use severity through positive alcohol expectancies. In a cross-sectional design, social drinkers (N = 200; 51% female; Mage = 26 years) completed self-report measures of trait (rash) impulsivity, Cluster-B personality disorder (PD) traits, positive alcohol expectancies, and alcohol use severity. Simple and serial mediation analyses were used to test positive alcohol expectancies and the association between trait impulsivity and alcohol expectancies as potential mediators of personality disorder trait relations with alcohol use severity. Simple mediation analyses evidenced that trait impulsivity and traits specific to each of the Cluster-B (PDs) were indirectly associated with alcohol use severity through positive alcohol expectancies. Serial mediation analyses further evidenced that the Cluster-B (PD) traits were indirectly associated with alcohol use severity via positive alcohol expectancies both uniquely from and together with trait impulsivity. Current findings are novel and suggest that positive alcohol expectancies may be important to connecting the rashly impulsive aspects of Cluster-B (PDs) with greater alcohol use severity. However, current findings also suggest that features of the Cluster-B (PDs) probably increase risk for alcohol use disorder due to other reasons (e.g., other aspects of personality or forms of impulsivity).

RESUMO

BACKGROUND: Veterans often use cannabis for sleep despite limited evidence of its efficacy. Moreover, how sleep disturbances impact cannabis use longitudinally is unclear. We applied a behavioral economic framework to examine whether sleep disturbances and cannabis demand (i.e., relative value) were related risk-factors for future cannabis use and problems. METHODS: Veterans deployed post-9/11/2001 who reported past 6-month cannabis use at baseline (n = 126) completed surveys on their sleep disturbances, demand via the Marijuana Purchase Task (MPT), and cannabis use. Mediation analyses using Hayes' PROCESS Macro and zero-inflated negative binomial models tested indirect effects of baseline sleep disturbances on 12-month cannabis use frequency, quantity, and problems via 6-month cannabis demand (i.e., intensity, Omax, Pmax, and breakpoint). RESULTS: Only Omax (i.e., maximum expenditure for cannabis) was a significant mediator for 12-month cannabis use quantity and problems when examined concurrently with other demand indices after controlling for covariates. Intensity (i.e., purchase at zero cost) was a significant mediator for 12-month cannabis use frequency when examined concurrently with other demand indices in models controlling for lifetime cannabis use, but not past 30-day use at baseline. CONCLUSION: Cannabis demand, specifically intensity and Omax, may help to identify Veterans with sleep disturbances who are at increased risk for escalating their cannabis use. Subsequent research should assess the extent that sleep disturbances impact cannabis demand in the context of withdrawal, which will inform novel prevention and intervention strategies geared toward reducing negative cannabis-related outcomes among Veterans.

RESUMO

OBJECTIVE: Impulsivity is an established etiological risk factor for alcohol- and cannabis-related outcomes. However, limited work has focused on longitudinal associations between multiple trait impulsivity facets and indices of alcohol and cannabis use among military veterans-a contextually distinct population that evidence unique impulsive personality traits and substance use patterns. METHOD: A structural equation model (SEM) examined longitudinal associations between five UPPS-P impulsivity facets measured at baseline and six indices of alcohol and cannabis use (i.e., frequency, quantity, and problems) measured at 1-year follow-up among 361 returning Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND) veterans. RESULTS: Findings indicated baseline sensation seeking was significantly positively associated with 1-year alcohol use frequency (ß = .18); baseline negative urgency was positively associated with alcohol use problems (ß = .31); and baseline lack of perseverance (ß = .25) and sensation seeking (ß = .21) were positively associated with 1-year cannabis use problems. None of the baseline impulsivity facets were associated with 1-year alcohol use quantity, cannabis use frequency, or cannabis use quantity. CONCLUSIONS: Results provide preliminary support that impulsivity may play a unique role in understanding alcohol- and cannabis-related problems over time among veterans. Further, results suggest that specific impulsivity facets are prospectively associated with cannabis problems (i.e., lack of perseverance and sensation seeking) and alcohol problems (i.e., negative urgency). Findings reinforce the importance of differentially evaluating impulsivity-substance use associations within contextually distinct populations (e.g., adolescent, veteran), and highlight potentially meaningful intervention targets among veterans. However, replication is needed with stronger temporal controls and more diverse veteran subsamples. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

Although the Marijuana Problems Index (MPI) is widely used in studies with college student samples to reflect a unidimensional measure of cannabis-related problems, no studies have assessed the psychometric properties of the MPI in a college student population. The present study sought to resolve this gap in a sample of 879 college students reporting past-year cannabis use. Confirmatory factor analyses were used to test the factor structure of the unidimensional 23- and 18-item MPI and measurement invariance across gender. Bivariate correlations between the final factors, cannabis use history/frequency, and other substance use outcomes were used to examine concurrent and discriminant validities (i.e., vs. noncannabis outcomes). The 18-item (but not the 23-item) MPI demonstrated good model fit, measurement invariance across gender, adequate internal reliability, as well as concurrent and discriminant validities. Results support the use of the 18-item MPI over the 23-item MPI for conceptualizing problematic cannabis use, including the testing of gender-specific differences, among college students. Findings also reinforce the importance of evaluating the psychometric properties of widely used measures across samples. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

INTRODUCTION: Alcohol consumption on college campuses is a major public health concern. Extant literature has identified trauma exposure as a robust risk factor for problematic alcohol use in this at-risk population. However, the mechanisms underlying this association are less well-studied. Research indicates that bodily arousal is a fundamental feature of trauma exposure, and posits that internal stimuli (e.g., heart pounding) at the time of trauma may manifest into conditioned cues that can trigger posttraumatic responding and related symptomatology, including alcohol use. However, past work supporting these assertions has used paradigms purposefully designed to evoke memories of the trauma, making it difficult to ascertain whether the mechanism driving subsequent alcohol craving is the explicit memory cue or the associated bodily arousal. METHODS: The current study examined whether an implicit, trauma-relevant cue of bodily arousal (via voluntary hyperventilation) - independent of any explicit memory cue - would elicit increased desire to drink among 104 (Mage = 20.30; 61.5% female) trauma-exposed undergraduates. RESULTS: Results found no statistically significant difference in change in alcohol craving between the hyperventilation and control tasks. However, secondary analyses indicated that trauma type (i.e., interpersonal/non-interpersonal) may play an influential role in this relationship. More specifically, individuals reporting interpersonal trauma as their most traumatic event evidenced a significantly greater increase in desire to drink following hyperventilation compared to the non-interpersonal index trauma group. DISCUSSION: Generally, these findings suggest that bodily arousal may only serve as an implicit, trauma-relevant interoceptive cue that increases desire to drink within a specific subset of trauma-exposed college students (i.e., individuals indexing interpersonal trauma). Replication and extension are needed to further understand the influence of bodily arousal on subsequent alcohol use behavior, which will be critical to PTSD-alcohol use modeling and, ultimately, help in informing prevention- and treatment-oriented intervention efforts aimed at reducing problematic alcohol use on college campuses.

RESUMO

OBJECTIVE: Evidence suggests that social anxiety (SA) is a risk factor for problematic alcohol and cannabis use, particularly during states of social stress. Unfortunately, laboratory studies to date have overlooked decision-making mechanisms (e.g., use willingness) and contextual features of commonly used social stress tasks that may clarify what is driving these links. The current study begins to address this gap by testing the effects of SA and laboratory-induced peer rejection on acute alcohol and cannabis use willingness within a simulated party setting. METHOD: 80 emerging adults (18-25 years; 70% women) endorsing lifetime alcohol and cannabis use were randomly assigned to experience rejection or neutral social cues. They rated their willingness to use alcohol and cannabis before and after cue exposure within the simulated party. A hierarchical regression tested the main and interaction effects of SA symptoms and experimental condition (Rejection vs. Neutral) on alcohol and cannabis use willingness, controlling for past-year use frequency and willingness to accept any offers (e.g., food and nonalcoholic drinks). RESULTS: There were statistically significant main (but not interaction) effects of SA and experimental condition on cannabis use willingness. Higher SA and Rejection exposure were each associated with greater cannabis use willingness. There were neither main nor interaction effects on alcohol willingness. CONCLUSIONS: Results suggest that elevated SA increases cannabis use willingness across social contexts, regardless of Rejection exposure, while Rejection exposure increases use willingness similarly across levels of SA. Together, findings reinforce the need to consider social-contextual factors and polysubstance use in laboratory settings. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMO

BACKGROUND: Alcohol-related motor vehicle crashes are a major preventable cause of death in the United States. One potential factor that may modulate the influence of alcohol on driving-related cognitions and decision-making is trauma-related stress. Indeed, in addition to compelling research indicating that both acute trauma-related stress and acute alcohol consumption may independently affect driving-related risky decision-making, there is reason to believe that the combination of these antecedents may have an exacerbating effect. METHODS: The current study evaluated the influence of induction of acute trauma-related stress (via script-driven imagery) after alcohol consumption (0.06% Breath Alcohol Concentration [BrAC]) on driving-related cognitions - perceived likelihood of negative consequences and willingness to drive - among 25 trauma-exposed (currently symptomatic) adult drinkers from the community (M = 24.08; 36.0% female). RESULTS: Participants who were acutely exposed to trauma-related stress after alcohol consumption evidenced lower perceived likelihood of being pulled over by a police officer (ηp2 = 0.38, large effect size) and lower perceived likelihood of getting in an accident (ηp2 = 0.17, medium-to-large effect size) relative to participants exposed to a neutral cue; conversely, participants exposed to trauma-related stress after alcohol consumption evidenced greater willingness to drive (d = 1.16, large effect size) than participants exposed to a neutral cue. CONCLUSIONS: Generally, findings suggest that individuals with a trauma history that are acutely exposed to trauma-related stressors (e.g., reminders of their traumatic experience) may be particularly vulnerable to poorer driving-related decision-making after alcohol consumption. Results provide a meaningful target for the development of intoxicated driving prevention and intervention efforts geared specifically for individuals with trauma history.

RESUMO

OBJECTIVE: There is a lack of research on primary prevention of posttraumatic stress disorder (PTSD) symptoms and substance use among trauma-exposed populations. To guide the development of more effective prevention efforts, the current study sought to identify underlying coping mechanisms that impact PTSD-substance use co-occurrence. METHOD: A person-centered analytic approach (latent class analysis) examined PTSD-substance use co-occurrence typologies (classes) and identified theoretically adaptive (e.g., active coping) and maladaptive (e.g., denial) coping strategies that differentiated between classes among a sample of 1,270 trauma-exposed participants (Mage = 20.71, 73.5% female, 45.7% White). RESULTS: Latent class analysis identified five distinct typologies, reflective of extant epidemiological and etiological work. Generally, behavioral disengagement and self-blame coping increased the likelihood of being in more severe PTSD-illicit substance use (e.g., cocaine) comorbidity classes. Positive reframing and planning differentiated between low and moderate illicit substance typologies with moderate PTSD severity. Venting, acceptance, and self-distraction differentiated between asymptomatic and moderate PTSD severity typologies with low illicit substance use. CONCLUSIONS: Findings identify general coping strategies associated with increased likelihood of being in more severe comorbidity typologies, as well as several unique coping strategies associated with risk of transitioning between low/moderate PTSD and illicit substance use classes. Relevant interventions (e.g., trauma psychoeducation, guilt-reduction therapy, psychological first aid) that may be targets for future prevention-oriented work are discussed.

RESUMO

BACKGROUND AND OBJECTIVES: Research consistently demonstrates a link between social anxiety and alcohol-related problems; however, the majority of work has been retrospective, and conducted with adults. Despite an extensive literature highlighting coping-related motives as an underlying mechanism, real-time work presents mixed findings, and no published research has examined an adolescent sample using experimental psychopathology techniques. METHODS: The current study tested whether (1) history of social anxiety symptoms positively correlated with alcohol-related cognitions following laboratory-induced social stress, (2) state anxiety was positively correlated with alcohol-related cognitions, and (3) whether the nature of the stressor (performance versus rejection) impacted the strength of identified relations, in a sample of community-recruited adolescents reporting recent alcohol use. Participants (n = 114; Mage = 16.01; 64% girls) were randomly assigned to either a performance- or rejection-oriented task. RESULTS: Findings indicated that history of social anxiety symptoms was positively correlated with state anxiety elicited by both tasks. Further, history of social anxiety symptoms was not related to change in desire to drink, but was positively related to the belief that alcohol 'would make me feel better.' State anxiety was positively related to both desire to drink and relief outcome expectancies across both tasks. Finally, the nature of the task did not moderate responding. LIMITATIONS: Single site, community sampling confines interpretations, and the tasks did not fully perform as expected. CONCLUSIONS: Further study is needed; however, the current findings support the contention that socially-oriented distress may be a developmentally-relevant, malleable target for prevention efforts aimed at problematic alcohol use among adolescents.

RESUMO

Background and Objectives: Most individuals experience multiple potentially traumatizing events (PTEs); hence, it is important to consider count and types of PTEs (polytraumatization) in relation to post-trauma health. Notably, no research has examined polytraumatization typologies in relation to positive memory count and phenomenology. We examined (1) latent subgroupings of individuals based on PTE endorsements; and (2) relation of the optimal latent class solution to positive memory count and phenomenology. Design: Participants were 203 trauma-exposed adults (Mage = 35.40; 61.10% females); we used PTEs endorsed on the Life Events Checklist for DSM-5 as indicators for analyses. Results: Latent class analyses indicated a three-class solution differing in quantity and quality of PTE types: Low Experience, Predominant Interpersonal PTEs, and Predominant Non-Interpersonal PTEs. Further, more positive memories predicted membership in the Low Experience vs. other classes; greater sensory details of a positive memory predicted membership in the Low Experience vs. the Predominant Interpersonal PTEs Classes; and greater accessibility of a positive memory predicted membership in the Predominant Interpersonal PTEs vs. the Predominant Non-Interpersonal PTEs Classes. Conclusions: Results indicated three meaningful subgroups endorsing differing levels/types of PTEs; count, sensory details, and accessibility of positive memories, pending further investigation, may differentiate these subgroups.

RESUMO

OBJECTIVE: We examined predictors of clinically significant levels of psychological distress among individuals with upper limb loss (ULL). DESIGN: A multisite, cross-sectional study completed at six prosthetic rehabilitation centres throughout the United States. METHODS: Oral administration of a brief assessment battery to 307 participants with ULL including demographic variables, injury information, screening instruments for PTSD and depression, pain interference, and activity restriction measures. Hierarchical multinomial logit models were conducted. Outcome groups were created using recommended cut-off scores on brief screening measures of depression and PTSD. Final models were assessed including relative risk ratios and marginal effects. RESULTS: Over half of the sample screened positive for depression, PTSD, or both. Eight individuals exceeded the recommended cut-off score indicative of PTSD only (2.6%), and 106 participants (34.5%) screened positive for depression only. Moreover, 64 participants (20.8%) reported co-occurring PTSD and depression. Subsequent models revealed women and ethnic minority participants were more likely to have clinically significant levels of depression and PTSD. Greater restriction in activity and increased pain interference also predicted psychological distress. CONCLUSIONS: These findings indicate a significant number of individuals with ULL experience clinically significant levels of psychological distress, and routine clinical assessment of depression and PTSD is warranted. Women and individuals from ethnic minorities may be particularly at risk, regardless of the severity and cause of ULL. Restrictions in preferred and goal-directed activities and persistent pain are also contributing factors. Psychological interventions that address these issues are indicated. Statement of contribution What is already known on this subject? Research investigating psychological reactions and adjustment after limb loss has primarily focused on lower limb loss. Little research has investigated psychological adjustment or distress following upper extremity loss. Lower extremity limb loss is more likely to be from a disease process while upper extremity limb loss is more likely to be due to traumatic injuries. Upper extremity limb loss possesses a qualitatively different experience as upper limb amputation is more readily apparent to others, impacts activities of daily living, and limits instrumental function in social and non-verbal communication. What does this study add? A significant percentage of individuals with upper limb loss report significant levels of depression, PTSD, and mixed depression and PTSD. Moreover, women and minority clients were more likely to report clinically significant levels of depression and mixed PTSD and depression. Activity restriction and pain interference's contributions in the final model helped to elucidate the clinical picture of psychological distress for persons with upper extremity limb loss. Greater activity restriction and limitations from pain interference increased the likelihood of reporting clinically significant levels of psychological distress.

RESUMO

Background: Given that marijuana use is often associated with detrimental physical and mental health problems, research examining motives for its use is critical for effective remedial and preventive treatment. To date, the majority of research on marijuana use motives has used variable-centered analyses, which overlooks potentially meaningful heterogeneous response patterns and the associations of those patterns with other risk/protective factors. Methods: To address this gap, in the current study, we conducted a person-centered analysis (latent profile analysis) to identify subgroups of participants based on endorsed marijuana use motives, and examined the construct validity of the optimal class solution (covariates included sociodemographic (e.g., age), psychiatric (e.g., depression), and marijuana-use indices (e.g., use-frequency, use-related problems). Participants were 898 college students (Mage = 20.93, SDage = 3.10; 68.9% female) who completed an anonymous online survey examining substance use and psychological well-being, were 18 years or older, and endorsed lifetime marijuana use. Data were collected November 2016 through February 2018. Results: Results identified four unique classes of coping, conformity, social, and enhancement marijuana use motives: (a) "Low Motives" (37.6%), (b) "High Conformity" (4.9%), (c) "Low Conformity" (45.8%), and (d) "High Motives" (11.7%). In terms of covariates, higher motive classes tended to report more frequent and problematic use. The two classes uniquely characterized by conformity motives only differed on past-month marijuana use frequency. Conclusions/Importance: The current findings provide evidence that specific classes of motives were not only associated with marijuana use frequency and problems but other risk and protective factors, such as anxiety sensitivity and social support.

RESUMO

A growing body of work links posttraumatic stress disorder (PTSD) symptoms and substance use. Unfortunately, much of the literature has examined associations in isolation (e.g., alcohol only). Failure to account for simultaneous or concurrent substance use may limit conclusions that can be drawn from existing research, including the extent to which specific substances contribute differentially to PTSD symptom patterns. The current study examined differences in PTSD symptom profiles between individuals using one or both of the most commonly co-administered psychoactive substances - alcohol and marijuana. Trauma-exposed participants (N = 533; Mage = 21.15) comprised two mutually-exclusive groups: past-month alcohol-only use (n = 334) or past-month alcohol and marijuana use (n = 199). Cluster-level and symptom-level profile analyses evaluated mean differences and shape (parallelism) of PTSD symptom severity profiles between the groups. Follow-up analyses examined symptom-specific difference in PTSD symptom endorsement and severity. Overall, individuals using marijuana and alcohol evidenced greater PTSD negative cognition (30.8% greater) and hyperarousal (26.4% greater) symptom severity. Alcohol and marijuana users were more likely to endorse, and report greater severity of, mood-related PTSD negative cognition symptoms (e.g., anhedonia, negative affect) and externalizing hyperarousal symptom (e.g., irritability/aggression, risky behaviors) than alcohol-only users. Findings highlight important PTSD differences between individuals that are often lumped into homogenous categories of isolated substance users. Findings provide preliminary support for an 'additive' self-medication model between PTSD and polysubstance use. Lastly, findings indicate that mood-related negative cognition symptoms and externalizing hyperarousal symptoms may be important targets for PTSD-polysubstance use intervention.

RESUMO

Purpose: Examining the relationship between posttraumatic stress disorder and posttraumatic stress disorder symptom clusters (re-experiencing, avoidance, hyperarousal, emotional numbing) on three substance use measures among individuals with upper limb amputation due to traumatic injury - an understudied population with high rates of posttraumatic stress disorder.Methods: Multi-site, cross-sectional design. Participants (N = 236) were recruited from seven prosthetic rehabilitation centres across the USA and completed measures of PTSD, alcohol use, prescription medication overuse, and illicit drug use.Results: Twenty-six percent of participants screened positive for posttraumatic stress disorder, 39% for problematic alcohol use, 12% for prescription medication overuse, and 7% for illicit drug use. No association was found between posttraumatic stress disorder or posttraumatic stress disorder symptoms clusters on problematic alcohol use. However, hyperarousal symptoms increased odds of overusing prescription medication (odds ratio = 3.30); further, a positive screen for posttraumatic stress disorder increased odds of illicit drug use (odds ratio = 2.95).Conclusions: These findings demonstrate the importance of assessing psychological well-being and a variety of substance use behaviours following amputation from traumatic injury. These findings may also provide clinically-relevant targets for prevention and intervention regarding prescription medication and illicit substance use, such as incorporating evidence-based treatment for posttraumatic stress disorder hyperarousal symptoms (e.g., prolonged exposure) and/or integrated treatment for posttraumatic stress-substance misuse (e.g., Seeking Safety) into patients' long-term inpatient/outpatient rehabilitation plans.Implications for rehabilitationPosttraumatic stress disorder hyperarousal symptoms increased odds of overusing prescription medication among individuals with upper limb amputation due to traumatic injury; a positive screen for posttraumatic stress disorder increased odds of illicit drug use.Psychological assessments should be incorporated into treatment and rehabilitation plans following amputation from traumatic injury.Rehabilitation specialists should consider adding or integrating evidence-based treatment for posttraumatic stress disorder into patients' long-term rehabilitation plan to reduce risk for problematic substance use.Findings support calls by the Centre for Disease Control and Prevention to overhaul prescription medication guidelines, including the need to assess risk and address harms concerning overuse of prescription medication.

BACKGROUND: Previous reviews of the PTSD and cigarette smoking literature showed high PTSD-smoking comorbidity and problematic smoking outcomes (Feldner et al., 2007, Clinical Psychology Review, 27, 14-45; Fu et al., 2007, Nicotine & Tobacco Research, 9, 1071-1084). However, past reviews also noted several prominent gaps in the literature, including a lack of etiological work examining underlying mechanisms and research on specialized PTSD-smoking treatments. The present review summarizes an extensive body of research conducted since the previous reviews targeting these areas of need. METHODS: Literature searches identified 66 empirical studies specific to smoking and PTSD. RESULTS: Smokers were approximately twice more likely to have PTSD than nonsmokers in the general population, and individuals with PTSD were approximately twice as likely to be current smokers. Smokers with PTSD evidenced more negative affect, trauma history, and comorbid psychiatric history, as well as quit attempts and higher relapse rates. PTSD symptoms were associated with expectations that smoking would reduce negative affect, which, in turn, was associated with increased smoking rate and nicotine dependence. Male sex was associated with nicotine dependence and PTSD avoidance, while the relationship between PTSD and smoking relapse due to withdrawal was stronger in females. Specialized, integrated PTSD and smoking cessation treatments showed promise in increasing quit success relative to standard care in randomized trials. CONCLUSIONS: Rates of PTSD-smoking co-occurrence remain high. Notable gains have been made in relevant epidemiological and etiological research, although more work is needed in trauma-specific subpopulations. Several promising specialized treatments for comorbid smoking-PTSD have been developed and empirically tested but require replication.

RESUMO

Caffeine is the most widely available and consumed psychoactive substance in the United States. Extant work indicates that across substances, use expectancies play a marked role in the development and maintenance of consumption patterns. Despite a burgeoning line of etiological and intervention-oriented research focused on expectancies (e.g., alcohol), there is a limited literature regarding caffeine use effect expectancies, specifically. To facilitate this work, the Caffeine Expectancy Questionnaire (CaffEQ) was developed and psychometrically validated; however, the length of the CaffEQ (i.e., 47 items) may hinder widespread adoption of this tool. As such, the current study provides an initial psychometric validation of a brief, 20-item version-the Brief-Caffeine Expectancy Questionnaire (B-CaffEQ)-in a multiethnic sample of undergraduate students (N = 975). Results showed that the B-CaffEQ replicated the 7-factor structure of the original CaffEQ using both constrained (confirmatory factor analysis) and less constrained (exploratory structural equation modeling) structural models and evidenced good internal consistency across subscales. The B-CaffEQ also demonstrated concurrent validity with caffeine use frequency indices, replicated and extended convergent validity between caffeine expectancy subscales and related behavioral and psychological constructs, and demonstrated discriminant validity with other related, but notably distinct, stimulant use metrics (e.g., cocaine, Ritalin). Lastly, the B-CaffEQ appears to provide an invariant measure of expectancies across types of caffeine users. These findings indicate that the B-CaffEQ is a reliable assessment of caffeine use effect expectancies, with acceptable-to-good psychometric properties-comparable in length to other substance use expectancies measures-that may be more readily incorporated into research and clinical settings.

RESUMO

OBJECTIVES: (1) To develop a performance-based measure for adult upper limb (UL) prosthetic functioning through broad (ie, overall performance) and functional domain-specific (eg, control skills) assessment of commonplace activities; (2) to conduct initial psychometric evaluation of the Capacity Assessment of Prosthetic Performance for the Upper Limb (CAPPFUL). DESIGN: Internal consistency of CAPPFUL and interrater reliability for task, functional domain, and full-scale (sub)scores among 3 independent raters were estimated. Known-group validity was examined comparing scores by amputation level. Convergent validity was assessed between CAPPFUL and 2 hand dexterity or function tests; discriminant validity was assessed against self-reported disability. SETTING: Six prosthetic rehabilitation centers across the United States. PARTICIPANTS: Subjects (N=60) with UL amputation using a prosthesis. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Not applicable. RESULTS: Interrater reliability was excellent for scoring on the task, domain, and full-scale scores (intraclass correlation coefficients=.88-.99). Internal consistency was good (α=.79-.82). Generally, subjects with higher UL amputation levels scored lower (worse) than subjects with lower UL amputation levels. CAPPFUL demonstrated strong correlations with measures of hand dexterity or functioning (rs=-.58 to .72) and moderate correlation with self-reported disability (r=-.35). CONCLUSIONS: CAPPFUL was designed as a versatile, low-burden measure of prosthesis performance for any UL functional prosthetic device type and any UL amputation level. CAPPFUL assesses overall performance and 5 functional performance domains during completion of 11 tasks that require movement in all planes while manipulating everyday objects requiring multiple grasp patterns. Psychometric evaluation indicates good interrater reliability, internal consistency, known-group validity, and convergent and discriminant validity.
