Booster effects and mechanisms of web-based personalised normative feedback alcohol intervention for college students: A pragmatic randomised controlled trial.

BACKGROUND: To evaluate the effects of booster and no booster versions of web-based alcohol Personalised Normative Feedback (PNF) and whether descriptive norms mediated and/or participant motivation moderated the effectiveness of the intervention in real world conditions (i.e. no financial incentives). METHODS: Pragmatic randomised controlled trial with 1-, 3-, and 6-month assessments. Brazilian college students reporting alcohol use in the last 12 months (N=931) were recruited from May/2020 to December/2022 and allocated to 1) No booster/single PNF(S-PNF); 2) Booster/multiple PNF(M-PNF); or 3) Assessment-only control. We applied Helmert coding [1: Any intervention (S-PNF or M-PNF) vs. Control; and 2: S-PNF vs. M-PNF]. PRIMARY OUTCOMES: typical number of drinks/week and maximum number of drinks/week; secondary outcomes: drinking frequency and number of consequences. Three-months assessment was the primary interval. Descriptive norms were tested as mediator. Interest, importance, and readiness to change were examined as moderators. RESULTS: Compared to control, any intervention did not influence primary outcomes at 3-months or 6-months, but did at 1-month, when reduced typical drinking (IRR:0.77, 95%CI:0.66;0.90) and maximum number of drinks (IRR:0.69, 95%CI:0.58;0.82). There was an intervention effect on the consequences at 3-months. No differences were observed between S-PNF and M-PNF. No mediation effects were found at 3-months. At 6-months, there was an indirect effect on typical drinking through norms at 3-months (b=-0.82, 95%CI:-2.03;-0.12) and effects on maximum drinks through norms at 1-month (b=-0.54, 95%CI:-1.65;-0.02). No support for moderation was found. CONCLUSIONS: Intervention reduced alcohol drinking at 1 month only and was not effective thereafter. Mechanisms of effect remain unclear.

Mental health and burnout during medical school: Longitudinal evolution and covariates.

BACKGROUND: Medical students' rate of depression, suicidal ideation, anxiety, and burnout have been shown to be higher than those of the same-age general population. However, longitudinal studies spanning the whole course of medical school are scarce and present contradictory findings. This study aims to analyze the longitudinal evolution of mental health and burnout from the first to the last year of medical school using a wide range of indicators. Moreover, biopsychosocial covariates that can influence this evolution are explored. METHOD: In an open cohort study design, 3066 annual questionnaires were filled in by 1595 different students from the first to the sixth year of the Lausanne Medical School (Switzerland). Depression symptoms, suicidal ideation, anxiety symptoms, stress, and burnout were measured along with biopsychosocial covariates. The longitudinal evolution of mental health and burnout and the impact of covariates were modelled with linear mixed models. RESULTS: Comparison to a same-aged general population sample shows that medical students reported significantly more depression symptoms and anxiety symptoms. Medical students' mental health improved during the course of the studies in terms of depression symptoms, suicidal ideation, and stress, although suicidal ideation increased again in the last year and anxiety symptoms remained stable. Conversely, the results regarding burnout globally showed a significant worsening from beginning to end of medical school. The covariates most strongly related to better mental health and less burnout were less emotion-focused coping, more social support, and more satisfaction with health. CONCLUSION: Both improvement of mental health and worsening of burnout were observed during the course of medical school. This underlines that the beginning and the end of medical school bring specific challenges with the first years' stressors negatively impacting mental health and the last year's difficulties negatively impacting burnout.

Young adults' change talk within brief motivational intervention in the emergency department and booster sessions is associated with a decrease in heavy drinking over 1 year.

OBJECTIVE: Investigate the effect of change talk (CT) within successive brief motivational interventions (BMIs) as a mechanism of change for alcohol use. METHOD: We conducted a secondary analysis of data from a randomized controlled trial in which 344 young adults (18-35 years old) admitted to a Swiss emergency department with alcohol intoxication received either BMI (N = 171) or brief advice (N = 173). Participants with a baseline audio-recorded BMI were included (N = 140; median age 23 [Q1-Q3: 20-27], 72.9% men). Up to three booster sessions by phone were offered at 1 week, 1 month, and 3 months. Percent CT and CT Average Strength were used as predictor variables. The outcome was the number of heavy drinking days (HDD) over the 30 days prior to research assessments at 1-, 3-, 6-, and 12-month follow-up. A latent growth curve modeling framework was first used to estimate predictor and outcome variable growth parameters (i.e., intercept and slope) over time, and then to regress HDD growth parameters on CT growth parameters. RESULTS: CT increased specifically from baseline to the 1-week booster session and thereafter remained stable. Higher baseline CT was associated with lower HDD at 1 month (Percent CT: b = -0.04, 95% confidence interval [-0.06, -0.01]; Average Strength: b = -0.99 [-1.67, -0.31]). An increase in CT from baseline to the 1-week booster session was related to a decrease in HDD from 1 month to 12 months (Percent CT: b = -0.08 [-0.14, -0.03]; Average Strength: b = -2.29 [-3.52, -1.07]). CONCLUSIONS: Both baseline CT and CT trajectory over the first week are meaningful predictors of HDD. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Substance use and its association with mental health among Swiss medical students: A cross-sectional study.

BACKGROUND: Studies on mental health and substance use among medical students indicated worrying prevalence but have been mainly descriptive. AIM: To evaluate the prevalence of substance use in a sample of medical students and investigate whether mental health variables have an influence on substance use. METHODS: The data were collected as part of the first wave of the ETMED-L, an ongoing longitudinal open cohort study surveying medical students at the University of Lausanne (Switzerland). N = 886 students were included and completed an online survey including measures of mental health (depression, suicidal ideation, anxiety, stress, and burnout) and use of and risk related with several substances (tobacco, alcohol, cannabis, cocaine, stimulants, sedatives, hallucinogens, opioids, nonmedical prescription drugs, and neuroenhancement drugs). We evaluated the prevalence of use of each substance and then tested the association between mental health and substance use in an Exploratory Structural Equation Modeling framework. RESULTS: Statistical indices indicated a four-factor solution for mental health and a three-factor solution for substance use. A factor comprising risk level for alcohol, tobacco, and cannabis use - which were the most prevalent substances - was significantly associated with a burnout factor and a factor related to financial situation and side job stress. There was a significant association between a factor comprising depression, anxiety, and suicidal ideation and a factor related to the use of sedatives, nonmedical prescription drugs and neuroenhancement drugs. Although their use was less prevalent, a factor comprising the risk level of stimulants and cocaine use was significantly but more mildly related to the burnout factor. A factor comprising stress related to studies and work/life balance as well as emotional exhaustion was not related to substance use factors. CONCLUSION: In this sample of medical students, the prevalence of substance use was substantial and poorer mental health status was related with higher substance use risk levels.

Mediational Analyses of the Effects of Social Behaviour and Network Therapy on Alcohol Use.

INTRODUCTION: Social behaviour and network therapy involves an active participation of the practitioner in recruiting a supportive network to change the client's alcohol use. Despite achieving beneficial effects on alcohol consumption, its possible mechanisms of change are a relatively under-studied topic compared to those of other alcohol treatment interventions. This study aimed to explore therapist skills through which social behaviour and network therapy may achieve effects on alcohol consumption in comparison with motivational enhancement therapy. METHODS: This study was secondary analysis of data from the UK Alcohol Treatment Trial, a multicentre, pragmatic, randomized controlled trial. The sample comprised 376 participants randomized to motivational enhancement therapy or social behaviour and network therapy. We used the UK Alcohol Treatment Trial Process Rating Scale to assess therapist skills. Outcomes drinks per drinking day and percentage of days abstinent were assessed 12 months after treatment initiation. Analyses were conducted in a simple mediation framework. RESULTS: Therapist skills score (combining frequency and quality) for involving others in behaviour change mediated social behaviour and network therapy effects on percentage of days abstinent (b = 0.06, 95% CI: 0.02; 0.10, p = 0.01). The frequency with which therapists acted as an active agent for change also mediated the effects of social behaviour and network therapy on percentage of days abstinent (b = 0.03, 95% CI: 0.003; 0.05, p = 0.03). The frequency with which the therapist stressed social support as a key factor in achieving change unexpectedly mediated an increase in drinks per drinking day (b = 0.10, 95% CI: 0.01; 0.18, p = 0.02). The two latter mediation effects were not sustained when quality was considered. All other indirect effects tested were non-significant. DISCUSSION/CONCLUSIONS: How social behaviour and network therapy exerts effects on alcohol outcomes is not yet well understood and in this study was not attributable to observed ratings of therapist treatment-specific skills. Therapist skill in planning the involvement of others during treatment, however, warrants further study. We suggest that the present findings should be regarded as hypothesis generating as it identifies specific targets for further investigation in alcohol treatment process studies.

Who benefits from brief motivational intervention among young adults presenting to the emergency department with alcohol intoxication: A latent-class moderation analysis.

BACKGROUND: Research has not identified which patients optimally benefit from brief Motivational Interviewing (bMI) for heavy drinking when delivered to young adults in the Emergency Department (ED). METHODS: We conducted secondary analyses of data from a randomized controlled trial in which 344 young adults (18-35 years) presenting to the ED with alcohol intoxication received either bMI or Brief Advice (BA, control group). We used Latent Class Analysis to derive participants' profiles from baseline characteristics (i.e., sex, age, severity of alcohol use disorder, attribution of ED admission to alcohol use, importance, and confidence to change, cognitive discrepancy, anxiety, depression, and trait reactance). We then conducted a moderation analysis to assess the number of heavy drinking days at short-term (1-month) and long-term (12-month) follow-up using negative binomial regressions with interactions between the intervention and derived classes. RESULTS: Fit statistics indicated that a 4-class solution best fit the data. Class 3 (high severity, importance and discrepancy, and low confidence and anxiety) benefitted more from bMI than BA at short- and long-term follow-up than Class 1 (younger; lowest severity, importance, discrepancy, reactance, anxiety and depression, and highest confidence). Class 2 (older; highest severity, importance, discrepancy, reactance, anxiety and depression, and lowest confidence) also benefitted more from bMI than BA than did Class 1 at short-term follow-up. In these significant contrasts, Class 1 benefitted more from BA than bMI. There were no significant interactions involving Class 4 (more likely to be women; low severity; high levels of anxiety, depression, and reactance). CONCLUSIONS: This study identified the patient profiles that benefitted more from bMI than BA among nontreatment-seeking young adults who present intoxicated to the ED. The findings have implications for intervention design and argue for the importance of research aimed at developing intervention content tailored to patient profiles.

Effect of a Novel Brief Motivational Intervention for Alcohol-Intoxicated Young Adults in the Emergency Department: A Randomized Clinical Trial.

Importance: Heavy drinking among young adults is a major public health concern. Brief motivational interventions in the emergency department have shown promising but inconsistent results. Objective: To test whether young adults receiving a newly developed brief motivational intervention reduce their number of heavy drinking days and alcohol-related problems over 1 year compared with participants receiving brief advice. Design, Setting, and Participants: This randomized clinical trial was conducted at an emergency department of a tertiary care university hospital in Lausanne, Switzerland. Recruitment ran from December 2016 to August 2019. Follow-up was conducted after 1, 3, 6, and 12 months. All adults aged 18 to 35 years presenting for any cause and presenting with alcohol intoxication were eligible (N = 2108); 1764 were excluded or refused participation. Follow-up rate was 79% at 12 months and 89% of participants provided follow-up data at least once and were included in the primary analyses. Statistical analysis was performed from September 2020 to January 2021. Interventions: The novel intervention was based on motivational interviewing and comprised in-person discussion in the emergency department and up to 3 booster telephone calls. The control group received brief advice. Main Outcomes and Measures: Primary outcomes were the number of heavy drinking days (at least 60 g of ethanol) over the previous month and the total score on the Short Inventory of Problems (0-45, higher scores indicating more problems) over the previous 3 months. Hypotheses tested were formulated before data collection. Results: There were 344 young adults included (median [IQR] age: 23 [20-28] years; 84 women [24.4%]). Among the 306 participants providing at least 1 follow-up point, a statistically significant time × group interaction was observed (ß = -0.03; 95% CI, -0.05 to 0.00; P = .02), and simple slopes indicated an increase of heavy drinking days over time in the control (ß = 0.04; 95% CI, 0.02 to 0.05; P < .001) but not in the intervention group (ß = 0.01; 95% CI, -0.01 to 0.03; P = .24). There was no effect on the Short Inventory of Problems score (ß = -0.01; 95% CI, -0.03 to 0.02; P = .71). Conclusions and Relevance: This randomized clinical trial found that a brief motivational intervention implemented in the emergency department provided beneficial effects on heavy drinking, which accounts for a substantial portion of mortality and disease burden among young adults. Trial Registration: ISRCTN registry: 13832949.

The relationship between medical students' empathy, mental health, and burnout: A cross-sectional study.

OBJECTIVE: To investigate how medical students' empathy is related to their mental health and burnout. METHODS: This cross-sectional study included 886 medical students from curriculum years 1-6. The cognitive, affective, and behavioural dimensions of empathy were measured with self-report questionnaires and an emotion recognition test. Regressions were used to test the relationship between the empathy dimensions, depressive symptoms, anxiety, and burnout as well as the influence of curriculum year and gender. RESULTS: Cognitive and behavioural empathy were significantly related to less mental health issues and burnout, whereas affective empathy was related to more mental health issues and burnout. Students in later curriculum years reported less mental health issues and burnout than students in earlier years, whereas no systematic difference could be observed for empathy. Female students reported more mental health issues and burnout as well as higher empathy, except for behavioural empathy for which male students scored higher. CONCLUSIONS: The cognitive, affective, and behavioural dimensions of empathy were differently related to the mental health and burnout of medical students. Students presenting mental health issues or burnout might have more difficulty to adapt their behaviour in social situations and keep a certain distance when taking others' perspective.

Behavioral economics indices predict alcohol use and consequences in young men at 4-year follow-up.

BACKGROUND AND AIMS: The alcohol purchase task (APT), which presents a scenario and asks participants how many drinks they would purchase and consume at different prices, generates indices of alcohol reward value that have shown robust associations with alcohol-related outcomes in numerous studies. The aim was to test its prospective validity at 4-year follow-up. DESIGN: Prospective cohort study. SETTING: General population sample of young Swiss men. PARTICIPANTS: A total of 4594 Swiss young men (median age = 21, 25th - 75th quartiles = 20.5 - 21.5) completed baseline questionnaires; among those, 4214 (91.7%) were successfully followed-up 4 years later. MEASUREMENTS: Alcohol reward value parameters (i.e. intensity, the planned consumption when drinks are free; breakpoint, the price at which consumption would be suppressed; Omax , the maximum alcohol expenditure; Pmax , the price associated with Omax ; and elasticity, the relative change in alcohol consumption as a function of the relative change in price) were derived from the APT at baseline and used to predict self-reported weekly drinking amount, monthly binge drinking, alcohol-related consequences and DSM-5 alcohol use disorder criteria. FINDINGS: Regression analyses, adjusting for the baseline alcohol measure, age, linguistic region and socio-economic indicators showed that intensity, breakpoint, Omax and elasticity significantly predicted all tested outcomes in the expected direction (e.g. standardized incidence rate ratio [95% confidence interval] = 1.11 [1.07-1.15], 1.07 [1.03-1.10], 1.08 [1.04-1.11], and 0.92 [0.89-0.95], respectively, for weekly drinking amount, all P < 0.001). Pmax did not significantly predict any outcomes. Non-adjusted correlations, baseline adjusted regression and ancillary analyses using (1) latent alcohol variables, (2) multiple imputation for missing data and (3) replications in training and testing subsamples to evaluate predictive accuracy provided consistent findings. CONCLUSIONS: The alcohol purchase task demand curve measures of alcohol reward value are useful in characterizing alcohol-related risk in young men and have long-term predictive utility.

Serial mediation analysis of treatment-specific processes in two contrasting alcohol treatments.

INTRODUCTION: This study explored whether treatment-specific processes linking therapist behaviors, post-session client ratings, and 3-month proximal outcomes (i.e., end of treatment) can explain 12-month outcomes for two contrasting alcohol treatment conditions with equivalent overall outcomes. METHODS: This study is a secondary analysis of the UK Alcohol Treatment Trial (UKATT), a multi-center randomized controlled trial of treatment for alcohol problems comparing 3-session motivational enhancement therapy (MET) to 8-session social behaviour and network therapy (SBNT). Among 742 adult clients included in UKATT, 351 had one treatment session recorded and coded and were followed-up 3 and 12 months after baseline. The study team conducted serial mediation analyses to test whether the frequency and quality of MET and SBNT skills were related to 12-month alcohol outcomes (drinks per drinking day) through postsession client ratings of treatment progress (Processes of Change Questionnaire, PCQ), readiness to change (RTC) and social support for drinking after 3-months. RESULTS: Higher quality of MET skills was related to higher PCQ scores, which were in turn related to greater post-treatment RTC, and subsequently to better alcohol outcomes. Total indirect effect was consistently significant. In contrast, only PCQ was predictive of treatment outcome in the SBNT portion of the model. CONCLUSIONS: This study provides evidence from a large pragmatic trial that the quality of MET skills positively influences alcohol outcomes in part through improvements in motivation during treatment and actively trying to change when treatment ends. Research should explore the ways in which SBNT secured outcomes that were equivalent to MET.

Impact of physician empathy on patient outcomes: a gender analysis.

BACKGROUND: Empathy in primary care settings has been linked to improved health outcomes. However, the operationalisation of empathy differs between studies, and, to date, no study has concurrently compared affective, cognitive, and behavioural components of empathy regarding patient outcomes. Moreover, it is unclear how gender interacts with the studied dimensions. AIM: To examine the relationship between several empathy dimensions and patient-reported satisfaction, consultation's quality, and patients' trust in their physicians, and to determine whether this relationship is moderated by a physician's gender. DESIGN AND SETTING: Analysis of the empathy of 61 primary care physicians in relation to 244 patient experience questionnaires in the French-speaking region of Switzerland. METHOD: Sixty-one physicians were video-recorded with two male and two female patients. Six different empathy measures were assessed: two self-reported measures, a facial recognition test, two external observational measures, and a Synchrony of Vocal Mean Fundamental Frequencies (SVMFF), measuring vocally coded emotional arousal. After the consultation, patients indicated their satisfaction with, trust in, and quality of the consultation. RESULTS: Female physicians self-rated their empathic concern higher than their male counterparts did, whereas male physicians were more vocally synchronised (in terms of frequencies of speech) to their patients. SVMFF was the only significant predictor of all patient outcomes. Verbal empathy statements were linked to higher satisfaction when the physician was male. CONCLUSION: Gender differences were observed more often in self-reported measures of empathy than in external measures, indicating a probable social desirability bias. SVMFF significantly predicted all patient outcomes, and could be used as a cost-effective proxy for relational quality.

Study protocol for the ETMED-L project: longitudinal study of mental health and interpersonal competence of medical students in a Swiss university using a comprehensive framework of empathy.

INTRODUCTION: Physician interpersonal competence is crucial for patient care. How interpersonal competence develops during undergraduate medical education is thus a key issue. Literature on the topic consists predominantly of studies on empathy showing a trend of decline over the course of medical school. However, most existing studies have focused on narrow measures of empathy. The first aim of this project is to study medical students' interpersonal competence with a comprehensive framework of empathy that includes self-reported cognitive and affective empathy, performance-based assessments of emotion recognition accuracy, and a behavioural dimension of empathy. The second aim of the present project is to investigate the evolution of mental health during medical school and its putative link to the studied components of interpersonal competence. Indeed, studies documented a high prevalence of mental health issues among medical students that could potentially impact their interpersonal competence. Finally, this project will enable to test the impact of mental health and interpersonal competence on clinical skills as evaluated by experts and simulated patients. METHODS AND ANALYSIS: This project consists of an observational longitudinal study with an open cohort design. Each year during the four consecutive years of the project, every medical student (curriculum years 1-6) of the University of Lausanne in Switzerland will be asked to complete an online questionnaire including several interpersonal competence and mental health measures. Clinical skills assessments from examinations and training courses with simulated patients will also be included. Linear mixed models will be used to explore the longitudinal evolutions of the studied components of interpersonal competence and mental health as well as their reciprocal relationship and their link to clinical skills. ETHICS AND DISSEMINATION: The project has received ethical approval from the competent authorities. Findings will be disseminated through internal, regional, national and international conferences, news and peer-reviewed journals.

Motivational interviewing technical and relational skills, change talk, and alcohol outcomes-A moderated mediation analysis.

Objective: Change talk has been proposed as a mechanism of change in motivational interviewing (MI) by mediating the link between MI technical skills and behavioral outcomes. We tested the influence of therapists' relational skills on this mediation model. Method: Secondary analysis of a randomized controlled trial of individual brief MI for heavy drinking among 20-year-old-Swiss young men, where the MI group (n = 179) significantly reduced drinking compared to an assessment-only control. We coded MI sessions and derived: therapists' MI technical skills, clients' change talk (CT) and sustain talk (ST), and global relational ratings (empathy and MI spirit). We tested moderated mediation models with technical skills as the independent variable, CT and ST as parallel mediators, predicting drinking at 3-month follow-up (controlling for baseline drinking), and relational skills as moderators of the path from technical skills to client mediators. Results: Conditional indirect effects were significant for overall MI technical skills, open questions, and simple reflections (i.e., more of these behaviors related to more ST, which was related to more drinking) when relational skills were low. In contrast, there was a significant conditional indirect effect for complex reflections when relational skills were high (i.e., more complex reflections related to less ST). Conclusions: This study provides partial support for the MI technical and relational process models. Interestingly, support was found regarding the negative side of client ambivalence (ST) in this highly precontemplative sample. Accordingly, MI therapists should work cautiously with ST when clients are at early stages of motivational readiness. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Evolution of the Illegal Substances Market and Substance Users' Social Situation and Health during the COVID-19 Pandemic.

The outbreak of the COVID-19 pandemic and the measures taken for tackling it had the potential to lead to deep modifications in the supply of illegal drugs and to impact substance users' health and social situation. To investigate this, we used mixed methods, i.e., quantitative data collected with a brief questionnaire from substance users receiving opioid agonist treatment in a treatment centre in Switzerland (N = 49), and qualitative data obtained using semi-structured phone interviews among a sub-group of participants (N = 17). We repeated data collection twice over four weeks to investigate trends over time (N = 51 and 14 at wave 2). Findings consistently showed the limited impact of the COVID-19 outbreak on the illegal substance market. Over the two waves, the supply, price and purity of three main illegal substances did not significantly vary. Substance use was estimated as usual by most, trending toward a decrease. The impact of the pandemic on participants' social situation and health was appraised as low to medium. Nevertheless, a minority of participants reported higher impact and multivariate analyses showed a more important impact for those who were female, younger, and not using multiple substances. This process was implemented quickly and provided an understanding of the short-term impact of the pandemic on drug markets and users.

Developing a brief motivational intervention for young adults admitted with alcohol intoxication in the emergency department - Results from an iterative qualitative design.

BACKGROUND: Unhealthy alcohol use among young adults is a major public health concern. Brief motivational interventions for young adults in the Emergency Department (ED) have shown promising but inconsistent results. METHODS: Based on the literature on brief intervention and motivational interviewing efficacy and active ingredients, we developed a new motivational intervention model for young adults admitted in the ED with alcohol intoxication. Using an iterative qualitative design, we first pre-tested this model by conducting 4 experimental sessions and 8 related semi-structured interviews to evaluate clinicians' and patients' perceptions of the intervention's acceptability and feasibility. We then conducted a consultation meeting with 9 international experts using a nominal group technique. The intervention model was adjusted and finally re-tested by conducting 6 new experimental sessions and 12 related semi-structured interviews. At each round, data collected were analyzed and discussed, and the intervention model updated accordingly. RESULTS: Based on the literature, we found 6 axes for developing a new model: High level of relational factors (e.g. empathy, alliance, avoidance of confrontation); Personalized feedback; Enhance discrepancy; Evoke change talk while softening sustain talk, strengthen ability and commitment to change; Completion of a change plan; Devote more time: longer sessions and follow-up options (face-to-face, telephone, or electronic boosters; referral to treatment). A qualitative analysis of the semi-structured interviews gave important insights regarding acceptability and feasibility of the model. Adjustments were made around which information to provide and how, as well as on how to deepen discussion about change with patients having low levels of self-exploration. The experts' consultation addressed numerous points, such as information and advice giving, and booster interventions. DISCUSSION: This iterative, multi-component design resulted in the development of an intervention model embedded in recent research findings and theory advances, as well as feasible in a complex environment. The next step is a randomized controlled trial testing the efficacy of this model.

Components evaluation of a web-based personalized normative feedback intervention for alcohol use among college students: a pragmatic randomized controlled trial with a dismantling design.

AIMS: To evaluate the effects of the two main components of a personalized normative feedback (PNF) [normative feedback only (NFO); and consequences feedback only (CFO)] compared with the full intervention (PNF) in reducing alcohol use and consequences. DESIGN: Three-arm pragmatic randomized controlled trial with dismantling design and 1-, 3- and 6-month follow-ups. SETTING: Web-based among Brazilian college students. PARTICIPANTS: College students (aged 18-30 years) who reported alcohol use in the last 3 months (n = 5476). INTERVENTIONS: (1) Full PNF (a) drinking profile; (b) normative comparisons; (c) practical costs; (d) alcohol consequences; (e) strategies to decrease risks; (2) NFO components (a), (b) and (e); or (3) CFO components (c), (d) and (e). MEASUREMENTS: The primary outcome was change in Alcohol Use Disorders Identification Test (AUDIT) score; secondary outcomes were the number of alcohol consequences, drinking frequency and typical/maximum number of drinks. We used mixed models with multiple imputation and a pattern-mixture model to account for attrition. Subgroup analyses considered participant motivation to know more about their drinking (less motivated versus motivated). FINDINGS: Dismantled components reduced rather than increased AUDIT score compared to full PNF, with significant effects for NFO at 1 month [b = -0.23, 95% confidence interval (CI) = -0.46; -0.002] and for CFO at 3 months (b = -0.33, 95% CI = -0.62; -0.03). Compared with PNF, NFO reduced the number of alcohol consequences at 1 month (b = -0.16, 95% CI = -0.25; -0.06) and drinking frequency at 3 months (b = -0.42, 95% CI = -0.79; -0.05), but increased the number of typical drinks at 6 months (b = 0.38, 95% CI = 0.04; 0.72). CFO reduced drinking frequency at 3 months (b = -0.37, 95% CI = -0.73; -0.01). Attrition models confirmed all results, except for the NFO effect on typical drinks and drinking frequency. Subgroup analyses indicated superiority of dismantled components among the students less motivated in knowing more about their drinking. CONCLUSIONS: There was no evidence that either the normative or the consequences components of a web-based personalized normative feedback intervention to reduce alcohol use and its consequences contributed to intervention effects. There was some evidence of adverse effects of personalized normative feedback, and these results were driven by 20% of participants who were less motivated in knowing more about their drinking.

Modeling empathy as synchrony in clinician and patient vocally encoded emotional arousal: A failure to replicate.

Empathy is a well-defined active ingredient in clinical encounters. To measure empathy, the current gold standard is behavioral coding (i.e., trained coders attribute overall ratings of empathy to clinician behaviors within an encounter), which is labor intensive and subject to important reliability challenges. Recently, an alternative measurement has been proposed: capturing empathy as synchrony in vocally encoded arousal, which can be measured as the mean fundamental frequency of the voice (mean F0). This method has received preliminary support by one study (Imel, Barco, et al., 2014). We aimed to replicate this study by using 2 large samples of clinical interactions (alcohol brief motivational interventions with young adults, N = 208; general practice consultations, N = 204). Audio files were segmented to identify respective speakers and mean F0 was measured using speech signal processing software. All sessions were independently rated by behavioral coders using 2 validated empathy scales. Synchrony between clinician and patient F0 was analyzed using multivariate multilevel models and compared with high and low levels of empathy derived from behavioral coding. Findings showed no support for our hypothesis that mean F0 synchrony between clinicians and patients would be higher in high-empathy sessions. This lack of replication was consistent for both clinical samples, both behavioral coding instruments, and using measures of F0 synchrony occurring at both the session-level and minute-level. We considered differences in culture and language, patients' characteristics, and setting as explanations for this failure to replicate. Further replication testing and new developments regarding measurement methods and modeling are needed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
