Some go without a cigarette: characteristics of cannabis users who have never smoked tobacco.

OBJECTIVES: To estimate the prevalence of youth who use cannabis but have never been tobacco smokers and to assess the characteristics that differentiate them from those using both substances or neither substance. DESIGN: School survey. SETTING: Postmandatory schools. PARTICIPANTS: A total of 5263 students (2439 females) aged 16 to 20 years divided into cannabis-only smokers (n = 455), cannabis and tobacco smokers (n = 1703), and abstainers (n = 3105). OUTCOME MEASURES: Regular tobacco and cannabis use; and personal, family, academic, and substance use characteristics. RESULTS: Compared with those using both substances, cannabis-only youth were younger (adjusted odds ratio [AOR], 0.82) and more likely to be male (AOR, 2.19), to play sports (AOR, 1.64), to live with both parents (AOR, 1.33), to be students (AOR, 2.56), and to have good grades (AOR, 1.57) and less likely to have been drunk (AOR, 0.55), to have started using cannabis before the age of 15 years (AOR, 0.71), to have used cannabis more than once or twice in the previous month (AOR, 0.64), and to perceive their pubertal timing as early (AOR, 0.59). Compared with abstainers, they were more likely to be male (AOR, 2.10), to have a good relationship with friends (AOR, 1.62), to be sensation seeking (AOR, 1.32), and to practice sports (AOR, 1.37) and less likely to have a good relationship with their parents (AOR, 0.59). They were more likely to attend high school (AOR, 1.43), to skip class (AOR, 2.28), and to have been drunk (AOR, 2.54) or to have used illicit drugs (AOR, 2.28). CONCLUSIONS: Cannabis-only adolescents show better functioning than those who also use tobacco. Compared with abstainers, they are more socially driven and do not seem to have psychosocial problems at a higher rate.

Zuckerman's reivsed alternative five-factor model: Validation of the Zuckerman-Kuhlman-Aluja Personality Questionnaire in four French-speaking countries

The aim of this study was to analyze the replicability of Zuckerman's revised Alternative Five-factor model in a French-speaking context by validating the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) simultaneously in 4 French-speaking countries. The total sample was made up of 1,497 subjects from Belgium, Canada, France, and Switzerland. The internal consistencies for all countries were generally similar to those found for the normative U.S. and Spanish samples. A factor analysis confirmed that the normative structure replicated well and was stable within this French-speaking context. Moreover, multigroup confirmatory factor analyses have shown that the ZKA-PQ reaches scalar invariance across these 4 countries. Mean scores were slightly different for women and men, with women scoring higher on Neuroticism but lower on Sensation Seeking. Globally, mean score differences across countries were small. Overall, the ZKA-PQ seems an interesting alternative to assess both lower and higher order personality traits for applied or research purposes.

Association between non-medical prescription drug use and personality traits among young Swiss men.

AIM: To investigate the relationships between six classes of non-medical prescription drug use (NMPDU) and five personality traits. METHODS: Representative baseline data on 5777 Swiss men around 20 years old were taken from the Cohort Study on Substance Use Risk Factors. NMPDU of opioid analgesics, sedatives/sleeping pills, anxiolytics, antidepressants, beta-blockers and stimulants over the previous 12 months was measured. Personality was assessed using the Brief Sensation Seeking Scale; attention deficit-hyperactivity (ADH) using the Adult Attention-Deficit-Hyperactivity Disorder Self-Report Scale; and aggression/hostility, anxiety/neuroticism and sociability using the Zuckerman-Kuhlmann Personality Questionnaire. Logistic regression models for each personality trait were fitted, as were seven multiple logistic regression models predicting each NMPDU adjusting for all personality traits and covariates. RESULTS: Around 10.7% of participants reported NMPDU in the last 12 months, with opioid analgesics most prevalent (6.7%), then sedatives/sleeping pills (3.0%), anxiolytics (2.7%), and stimulants (1.9%). Sensation seeking (SS), ADH, aggression/hostility, and anxiety/neuroticism (but not sociability) were significantly positively associated with at least one drug class (OR varied between 1.24, 95%CI: 1.04-1.48 and 1.86, 95%CI: 1.47-2.35). Aggression/hostility, anxiety/neuroticism and ADH were significantly and positively related to almost all NMPDU. Sociability was inversely related to NMPDU of sedatives/sleeping pills and anxiolytics (OR, 0.70; 95%CI: 0.51-0.96 and OR, 0.64; 95%CI: 0.46-0.90, respectively). SS was related only to stimulant use (OR, 1.74; 95%CI: 1.14-2.65). CONCLUSION: People with higher scores for ADH, aggression/hostility and anxiety/neuroticism are at higher risk of NMPDU. Sociability appeared to protect from NMPDU of sedatives/sleeping pills and anxiolytics.

Controversies about the enhanced vulnerability of the adolescent brain to develop addiction.

Adolescence, defined as a transition phase toward autonomy and independence, is a natural time of learning and adjustment, particularly in the setting of long-term goals and personal aspirations. It also is a period of heightened sensation seeking, including risk taking and reckless behaviors, which is a major cause of morbidity and mortality among teenagers. Recent observations suggest that a relative immaturity in frontal cortical neural systems may underlie the adolescent propensity for uninhibited risk taking and hazardous behaviors. However, converging preclinical and clinical studies do not support a simple model of frontal cortical immaturity, and there is substantial evidence that adolescents engage in dangerous activities, including drug abuse, despite knowing and understanding the risks involved. Therefore, a current consensus considers that much brain development during adolescence occurs in brain regions and systems that are critically involved in the perception and evaluation of risk and reward, leading to important changes in social and affective processing. Hence, rather than naive, immature and vulnerable, the adolescent brain, particularly the prefrontal cortex, should be considered as prewired for expecting novel experiences. In this perspective, thrill seeking may not represent a danger but rather a window of opportunities permitting the development of cognitive control through multiple experiences. However, if the maturation of brain systems implicated in self-regulation is contextually dependent, it is important to understand which experiences matter most. In particular, it is essential to unveil the underpinning mechanisms by which recurrent adverse episodes of stress or unrestricted access to drugs can shape the adolescent brain and potentially trigger life-long maladaptive responses.

Personality and repeated suicide attempts in dependent adolescents and young adults.

This study compared personality characteristics of subjects with dependence disorders who had previously made a suicide attempt. The population, recruited in France, Belgium, and Switzerland, was composed of 570 subjects (225 females, 345 males, mean age = 27.3, SD = 8.5). The subjects' psychological dimensions were investigated by means of several self-report questionnaires including: BDI-13 (Beck), Sensation-Seeking Scale (Zuckerman), Toronto Alexithymia Scale (Taylor), Interpersonal Dependency Inventory (Hirschfeld), MMPI-2, and some additional scales. For most dimensions, repeat attempters, both past and recent, but more specifically the recent repeaters, had a more severe psychological profile compared to the other suicide attempters.

Predictors of onset of cannabis and other drug use in male young adults: results from a longitudinal study.

BACKGROUND: The use of cannabis and other illegal drugs is particularly prevalent in male young adults and is associated with severe health problems. This longitudinal study explored variables associated with the onset of cannabis use and the onset of illegal drug use other than cannabis separately in male young adults, including demographics, religion and religiosity, health, social context, substance use, and personality. Furthermore, we explored how far the gateway hypothesis and the common liability to addiction model are in line with the resulting prediction models. METHODS: The data were gathered within the Cohort Study on Substance Use Risk Factors (C-SURF). Young men aged around 20 years provided demographic, social, health, substance use, and personality-related data at baseline. Onset of cannabis and other drug use were assessed at 15-months follow-up. Samples of 2,774 and 4,254 individuals who indicated at baseline that they have not used cannabis and other drugs, respectively, in their life and who provided follow-up data were used for the prediction models. Hierarchical logistic stepwise regressions were conducted, in order to identify predictors of the late onset of cannabis and other drug use separately. RESULTS: Not providing for oneself, having siblings, depressiveness, parental divorce, lower parental knowledge of peers and the whereabouts, peer pressure, very low nicotine dependence, and sensation seeking were positively associated with the onset of cannabis use. Practising religion was negatively associated with the onset of cannabis use. Onset of drug use other than cannabis showed a positive association with depressiveness, antisocial personality disorder, lower parental knowledge of peers and the whereabouts, psychiatric problems of peers, problematic cannabis use, and sensation seeking. CONCLUSIONS: Consideration of the predictor variables identified within this study may help to identify young male adults for whom preventive measures for cannabis or other drug use are most appropriate. The results provide evidence for both the gateway hypothesis and the common liability to addiction model and point to further variables like depressiveness or practising of religion that might influence the onset of drug use.

Measuring alcohol-related consequences in school surveys: alcohol-attributable consequences or consequences with students' alcohol attribution.

In alcohol epidemiology surveys, there is a tradition of measuring alcohol-related consequences using respondents' attribution of alcohol as the cause. The authors aimed to compare the prevalence and frequency of self-attributed consequences to consequences without self-attribution using alcohol-attributable fractions (AAF). In 2007, a total of 7,174 Swiss school students aged 13-16 years reported the numbers of 6 alcohol-related adverse consequences (e.g., fights, injuries) they had incurred in the past 12 months. Consequences were measured with and without attribution of alcohol as the cause. The alcohol-use measures were frequency and volume of drinking in the past 12 months and number of risky single-occasion (> or =5 drinks) drinking episodes in the past 30 days. Attributable fractions were derived from logistic (> or =1 incident) and Poisson (number of incidents) regression analyses. Although relative risk estimates were higher when alcohol-attributed consequences were compared with nonattributed consequences, the use of AAFs resulted in more alcohol-related consequences (10,422 self-attributed consequences vs. 24,520 nonattributed consequences determined by means of AAFs). The likelihood of underreporting was higher among drinkers with intermediate frequencies than among either rare drinkers or frequent drinkers. Therefore, the extent of alcohol-related adverse consequences among adolescents may be underestimated when using self-attributed consequences, because of differential attribution processes, especially among infrequent drinkers.

Evidence for an overestimated vulnerability of adolescent rats to develop signs of drug addiction

Drug addiction is a multi-etiological disorder to which some individuals are more vulnerable an others. Whereas converging clinical and epidemiological studies report a peak of drug use ring adolescence, many behavioral traits characterizing teenagers have been proposed to contribute to this vulnerability, including a heightened sensation-seeking, an enhanced impulsivity d a larger influence exerted by peers. By many aspects, juvenile rodents display behavioral traits at resemble those of teenagers. However, the concept of increased vulnerability to drug addiction juvenile rats remains in debate. Indeed, only a few studies directly compared juvenile and adult fdents regarding behavioral predictors of drug abuse. Moreover, some key features of drug diction have never been investigated in juvenile rats yet. For this very reason, we conducted a arge-scale behavioral comparison of adult and adolescent rats with the aim of dissecting their espective behavioral traits and vulnerabilities to drug addiction. We first have shown that juvenile rats exhibited an enhanced motor impulsivity, and a loss of control over reward seeking assessed by a persistent reward taking despite adverse consequences mild electric footshocks]. We also report that juvenile rats displayed a higher anxiety profile, ind we discuss why these behaviors might represent key underpinning mechanisms leading to an enhanced vulnerability to drug abuse. Meanwhile, we collected clear cut observations that do not support such an interpretation. In Articular, juvenile and adult rats displayed identical novelty-induced habituation and preference at are considered to represent two potent predictors of cocaine initiation and compulsive intake, "pre strikingly, juvenile rats were less attracted by cues predicting reward in a Pavlovian utoshaping task, suggesting a lower propensity for cues or context to trigger the reinstatement of a^previously extinguished reward seeking behavior. Finally, using a paradigm assessing schedule- ciuced polydipsia, juvenile and adult rats exhibited similar compulsive drinking, under control conditions and following a chronic cocaine treatment as well. Hence, these observations call for a cautious interpretation of adolescent vulnerability to drug use. In particular, we underlined that even the most compulsive young rats did not consume ärger amounts of cocaine than adults, nor exhibited larger efforts in a cue-induced relapse aradigm, despite a transient increased motivation for lever-pressing. And further, despite a higher ensitivity to the behavioral effects of cocaine, juvenile rats did not differ from adults in their ropensity to constantly prefer saccharin over cocaine in a discrete-choice procedure, even after a ?'Id chronic stress procedure. Altogether, our results shape an objective overview of the juvenile rats' behavior in relation to oth drug and non-drug rewards, suggesting a heterogeneous and task-specific profile. Despite elements potentially underlying a real risk for substance use, adolescent rats do not exhibit a ehavioral repertoire suggesting increased vulnerability for compulsive drug abuse. Our conclusions strongly encourage deeper neurobiological investigations of the developing brain, and also open a debate on a possible overestimation of juvenile rats' and teenager's risk to develop aladaptive behaviors and drug addiction. - L'addiction aux drogues est une pathologie d'origine multifactorielle, à laquelle certains individus sont plus vulnérables que d'autres. De nombreuses études cliniques et épidémiologiques suggèrent une consommation excessive de drogues pendant l'adolescence, et plusieurs explications ont été avancées pour justifier cette tendance, parmi lesquelles on note une augmentation de la recherche de sensation, une impulsivité plus marquée et une plus forte influence de l'entourage. Le rat juvénile présente de nombreuses caractéristiques développementales similaires à l'adolescence humaine. En revanche, la vulnérabilité des rats juvéniles à l'abus de drogue est encore sujette à caution. En effet, peu d'études ont directement comparé des traits de comportements pouvant refléter un accroissement du risque d'abus chez les rats juvéniles par comparaison aux rats adultes. En outre, certaines caractéristiques fondamentales de l'addiction chez l'homme n'ont pas encore été étudiées chez le rat adolescent. Ce travail de thèse s'est donc donné pour objectif de comparer le comportement de rats adultes vis-à-vis de celui de rats adolescents, afin d'évaluer dans quelle mesure ces derniers seraient plus vulnérables à l'abus de drogues. Nos résultats indiquent que les rats juvéniles présentent une augmentation des comportements impulsifs, ainsi qu'une plus grande persistance à rechercher de manière compulsive une récompense en dépit de légers chocs électriques. Les rats juvéniles présentent également un profil anxieux plus élevé, ce qui peut constituer une autre source de vulnérabilité. Cependant, certaines caractéristiques comportementales ne suggèrent pas de vulnérabilité chez les rats juvéniles. Aucune différence entre rats adultes et adolescents n'a été trouvée pour l'habituation et la préférence pour la nouveauté, deux traits prédisant l'initiation et la prise compulsive de drogue. De plus, nous avons montré que les rats adolescents attribuent moins d'intérêt à des stimuli prédisant la disponibilité d'une récompense, suggérant une vulnérabilité plus faible à la rechute induite par les stimuli associés à la prise de drogue. Une étude complémentaire des comportements compulsifs indique une absence de différence entre rats adultes et adolescents, à la fois en condition basale ou après un traitement chronique à la cocaïne. L'étude des comportements de prise de drogue ne va pas non plus dans le sens d'une vulnérabilité des rats adolescents. Bien que les rats compulsifs sélectionnés pendant la période juvénile présentent une plus grande motivation à prendre de la cocaïne, ils ne diffèrent ni dans la quantité de cocaïne consommée, ni dans la rechute induite par les stimuli environnementaux. En dépit d'une sensibilisation comportementale plus importante, les rats adolescents présentent la même préférence que les adultes face à un choix entre une drogue et une récompense alternative, suggérant une résilience à la cocaïne comparable à celle des adultes. Enfin, cette résilience pour la cocaïne n'est pas affectée par un stress chronique lors de l'adolescence. En résumé, cette étude dresse un regard objectif sur les comportements en lien avec une vulnérabilité à l'abus de drogues chez le rat juvénile, suggérant que celle-ci est hétérogène et spécifique au protocole utilisé. En dépit de certains éléments de vulnérabilité, les rats adolescents ne présentent pas d'attirance excessive pour la cocaïne, ni de prédisposition à la consommation compulsive de cette drogue. L'ensemble de ces éléments pourra constituer une base solide pour l'investigation neurobiologique du cerveau en développement, et ouvre un débat sur une possible surestimation de la vulnérabilité des rats juvéniles et de leurs homologues humains aux pathologies psychiatriques telles que l'addiction aux drogues.

Violent adolescents and their educational environment: a multilevel analysis.

OBJECTIVE: This study examined the respective roles of personal and environmental factors in youth violence in a nationally representative sample of 7548 postmandatory school students and apprentices ages 16-20 years in Switzerland. METHODS: Youth violence was defined as having committed at least one of the following in the previous 12 months: attacking an adult, snatching something, carrying a weapon, or using a weapon in a fight. Different ecological levels were tested, resulting in a three-level model only in males (individual, classroom, and school) as the low prevalence of female violence did not allow for a multilevel analysis. Dependent variables were attributed to each level. For males, the classroom level (10%) and the school level (24%) accounted for more than one third in interindividual variance. RESULTS: Factors associated with violence perpetration in females were being a victim of physical violence and sensation seeking at the individual level. In males, practicing unsafe sex, sensation seeking, being a victim of physical violence, having a poor relationship with parents, being depressed, and living in a single-parent household at the individual level; violence and antisocial acts at the classroom level; and being in a vocational school at the school level showed a correlation with violence perpetration. CONCLUSION: Interventions at the classroom level as well as an explicit school policy on violence and other risk behaviors should be considered a priority when dealing with the problem of youth violence. Furthermore, prevention should take into account gender differences.

Risk perception, emotion regulation and impulsivity as predictors of risk behaviours among adolescents in Switzerland

The purpose of this study was to explore the frequency of risk behaviours among Swiss adolescents and their links with risk perception, impulsivity and emotion regulation abilities, operationalized with the concepts of alexithymia and emo- tional openness. We recruited 144 subjects (aged 14-20), who completed the Risk Involvement and Perception Scale (RIPS-R), the UPPS Impulsive Behavior Scale, the 20-item Toronto Alexithymia Scale (TAS-20), and the 20-item Dimensions of Openness to Emotional Experiences (DOE-20) questionnaire. Findings revealed that a greater perception of benefits and a higher level of sensation seeking were associated with more involvement in risk behaviours, which are essentially socially accepted behaviours. Notably, the path model indicated that the perception of benefits was a mediator in the relationship between sensation seeking and risk behaviours. The results add to the psychological understanding of factors associated with risk behaviours in adolescence. The limitations and implications of these results for developmental theories, research, and prevention are stated.

Liberal alcohol legislation: does it amplify the effects among Swiss men of person-related risk factors on heavy alcohol use?

AIM: To estimate the statistical interactions between alcohol policy strength and the person-related risk factors of sensation-seeking, antisocial personality disorder and attention-deficit/hyperactivity disorder related to heavy alcohol use. DESIGN: Cross-sectional survey. SETTING: Young Swiss men living within 21 jurisdictions across Switzerland. PARTICIPANTS: A total of 5701 Swiss men (mean age 20 years) participating in the Cohort Study on Substance Use Risk Factors (C-SURF). MEASUREMENTS: Outcome measures were alcohol use disorder (AUD) as defined in the DSM-5 and risky single-occasion drinking (RSOD). Independent variables were sensation-seeking, antisocial personality disorder (ASPD), attention-deficit/hyperactivity disorder (ADHD) and an index of alcohol policy strength. FINDINGS: Alcohol policy strength was protective against RSOD [odds ratio (OR) = 0.91 (0.84-0.99)], while sensation-seeking and ASPD were risk factors for both RSOD [OR = 1.90 (1.77-2.04); OR = 1.69 (1.44-1.97)] and AUD [OR = 1.58 (1.47-1.71); OR = 2.69 (2.30-3.14)] and ADHD was a risk factor for AUD [OR = 1.08 (1.06-1.10)]. Significant interactions between alcohol policy strength and sensation-seeking were identified for RSOD [OR = 1.06 (1.01-1.12)] and AUD [OR = 1.06 (1.01-1.12)], as well as between alcohol policy strength and ASPD for both RSOD [OR = 1.17 (1.03-1.31)] and AUD [OR = 1.15 (1.02-1.29)]. These interactions indicated that the protective effects of alcohol policy strength on RSOD and AUD were lost in men with high levels of sensation-seeking or an ASPD. No interactions were detected between alcohol policy strength and ADHD. CONCLUSION: Stronger alcohol legislation protects against heavy alcohol use in young Swiss men, but this protective effect is lost in individuals with high levels of sensation-seeking or having an antisocial personality disorder.

Parent-adolescent relationship in youths with a chronic condition.

BACKGROUND: Suffering from a chronic disease or disability (CDD) during adolescence can be a burden for both the adolescents and their parents. The aim of the present study is to assess how living with a CDD during adolescence, the quality of parent-adolescent relationship (PAR) and the adolescent's psychosocial development interact with each other. METHODS: Using the Swiss Multicenter Adolescent Survey on Health 2002 (SMASH02) database, we compared adolescents aged 16-20 years with a CDD (n = 760) with their healthy peers (n = 6493) on sociodemographics, adolescents' general and psychosocial health, interparental relationship and PAR. RESULTS: Bivariate analyses showed that adolescents with a CDD had a poorer psychosocial health and a more difficult relationship with their parents. The log-linear model indirectly linked CDD and poor PAR through four variables: two of the adolescents' psychosocial health variables (suicide attempt and sensation seeking), the need for help regarding difficulties with parents and a highly educated mother that acted as a protective factor, allowing for a better parent-adolescent with a CDD relationship. CONCLUSION: It is essential for health professionals taking care of adolescents with a CDD to distinguish between issues in relation with the CDD from other psychosocial difficulties, in order to help these adolescents and their parents deal with them appropriately and thus maintain a healthy PAR.

Latent Class Analysis of Gambling Activities in a Sample of Young Swiss Men : Association with Gambling Problems, Substance Use Outcomes, Personality Traits and Coping Strategies.

The study aimed to identify different patterns of gambling activities (PGAs) and to investigate how PGAs differed in gambling problems, substance use outcomes, personality traits and coping strategies. A representative sample of 4989 young Swiss males completed a questionnaire assessing seven distinct gambling activities, gambling problems, substance use outcomes, personality traits and coping strategies. PGAs were identified using latent class analysis (LCA). Differences between PGAs in gambling and substance use outcomes, personality traits and coping strategies were tested. LCA identified six different PGAs. With regard to gambling and substance use outcomes, the three most problematic PGAs were extensive gamblers, followed by private gamblers, and electronic lottery and casino gamblers, respectively. By contrast, the three least detrimental PGAs were rare or non-gamblers, lottery only gamblers and casino gamblers. With regard to personality traits, compared with rare or non-gamblers, private and casino gamblers reported higher levels of sensation seeking. Electronic lottery and casino gamblers, private gamblers and extensive gamblers had higher levels of aggression-hostility. Extensive and casino gamblers reported higher levels of sociability, whereas casino gamblers reported lower levels of anxiety-neuroticism. Extensive gamblers used more maladaptive and less adaptive coping strategies than other groups. Results suggest that gambling is not a homogeneous activity since different types of gamblers exist according to the PGA they are engaged in. Extensive gamblers, electronic and casino gamblers and private gamblers may have the most problematic PGAs. Personality traits and coping skills may predispose individuals to PGAs associated with more or less negative outcomes.

Quelle assistance psychologique pour les couples requérant une aide médicale à la procréation [Which psychological support for couples seeking medical assistance for procreation?]

OBJECTIVES: The objective of our qualitative study was to define modalities of psychological support to be offered to couples seeking medically assisted procreation. MATERIAL AND METHODS: Forty couples participated in a semi-structured videotaped interview, which touched on themes such as personal and family histories, the couple's relationship, etc. We focused on the "narrative mobility", that is the way in which the couples transmit their personal and family history during the interview and the interviewer's impression that he may or may not share this with the couples. RESULTS: Observed differences in narrative mobility led us to distinguish three groups of couples and to propose various types of psychological support. DISCUSSION AND CONCLUSION: This exploratory study, with its interest for the narrative mobility, concerns the couples' capacity to stand back from their own story as responsible interlocutors. We made the hypothesis that this capacity is linked to their capacity to handle their emotional stress, to act as partners to the medical team and to prepare themselves for their future parenthood.

A preliminary evaluation of the validity of at-risk criteria for bipolar disorders in help-seeking adolescents and young adults.

INTRODUCTION: We have developed ultra-high risk criteria for bipolar affective disorder (bipolar at-risk - BAR) which include general criteria such as being in the peak age range of the onset of the disorder and a combination of specific criteria including sub-threshold mania, depressive symptoms, cyclothymic features and genetic risk. In the current study, the predictive validity of these criteria were tested in help-seeking adolescents and young adults. METHOD: This medical file-audit study was conducted at ORYGEN Youth Health (OYH), a public mental health program for young people aged between 15 and 24years and living in metropolitan Melbourne, Australia. BAR criteria were applied to the intake assessments of all non-psychotic patients who were being treated in OYH on 31 January, 2008. All entries were then checked for conversion criteria. Hypomania/mania related additions or alterations to existing treatments or initiation of new treatment by the treating psychiatrist served as conversion criteria to mania. RESULTS: The BAR criteria were applied to 173 intake assessments. Of these, 22 patients (12.7%) met BAR criteria. The follow-up period of the sample was 265.5days on average (SD 214.7). There were significantly more cases in the BAR group (22.7%, n=5) than in the non-BAR group (0.7%, n=1) who met conversion criteria (p<.001). CONCLUSIONS: These findings support the notion that people who develop a first episode of mania can be identified during the prodromal phase. The proposed criteria need further evaluation in prospective clinical trials.
