RESUMEN
Objective: The objective of this study was to explore Swedish managers' and HR-officers' experiences and perceptions of skills training including a development and implementation of an alcohol policy. Methods: Semi-structured interviews were conducted with Swedish managers (n = 44) and HR-officers (n = 9) from nine different organizations whom had received skills training and an organizational policy implementation. The interviews were analyzed using thematic analyses. Results: In total, nine themes were identified as: The prevalence of alcohol problems: a wake-up call; a reminder to intervene immediately; an altered view of the responsibility of the employer; initiating conversations about alcohol: a useful toolbox; an imprecise, yet positive, memory; increased awareness of issues related to alcohol culture; I have not heard a word about a new alcohol policy; the alcohol policy: a mere piece of paper; and alcohol problem prevention: hardly a low-hanging fruit. Participants' experiences of the skills training were positive overall. Conclusion: Various aspects of the skills training were appreciated by managers and HR-officers, including insight of prevalence statistics and employer responsibilities. Participants emphasized the value of repeated skills training occasions for retaining knowledge. Future research may investigate further in what way skills training may affect managers' willingness to engage in workplace alcohol prevention. Since the implementation of any policy had gone unnoticed to participants, a reason for which could be related to the notion of the existing policy as "good enough" in its current condition, implementation and organizational issues, or a reluctance to address alcohol-related matters unless necessary; future research may focus on investigating in what manner alcohol policies are in fact utilized within organizations.
RESUMEN
ABSTRACT: The importance of personality traits for the outcome of psychiatric treatment, including treatment for alcohol use disorder (AUD), has been widely acknowledged. Also, research on autism spectrum disorders has evolved in recent years, emphasizing that the behavioral traits within these neuropsychiatric disorders exist on a dimension both within and outside the boundaries of psychopathology. In the present study, the relationship between personality traits associated with autistic functioning and level of alcohol use among patients before and after concluded AUD treatment was investigated. The participants (n = 165, diagnosed with AUD) were part of a longitudinal project on AUD treatment. Data from personality questionnaires (Structured Clinical Interview of Personality Disorders II and Temperament and Character Inventory) were used to assess autistic personality traits (APTs) based on behavior within Wing's triad, which were related to background and treatment outcome. The chosen APT items illustrated a personality functioning with an emphasis on social interaction and rigidity. Only certain included questions were indicative of still having a problematic drinking pattern 2.5 years after treatment entry, which adhered to phobic, obsessive-compulsive, and schizoid personality traits, as well as rigidity/stubbornness. Albeit with modest influence, the degree of APTs was associated with heavier drinking at treatment entry, and symptoms relating to social interaction and rigidity were associated with still having a problematic drinking pattern 2.5 years after treatment entry. A higher degree of such traits may result in having problems taking advice from others and establishing treatment alliance, important parts of treatment efficacy, making assessment of such traits relevant to clinicians.

BACKGROUND: To examine the relationship between treatment outcome, as measured according to change in alcohol consumption, and a history of childhood abuse (emotional, physical, sexual) in socially stable women undergoing treatment for alcohol use disorder (AUD). METHODS: Participants were assessed using the Addiction Severity Index and the Mini International Neuropsychiatric Interview at the beginning of treatment (n = 75), end of treatment (n = 59) and 12 month follow-up after treatment (n = 57). Self-report data on alcohol consumption were obtained at all three time-points using the Alcohol Habits Inventory-Revised 2. Self-report data on childhood maltreatment were obtained at the beginning of treatment using the Childhood Trauma Questionnaire-short form. Study outcomes were changes in alcohol consumption (grams of pure alcohol per week), risk-drinking and reported abstinence. RESULTS: Of the 75 women enrolled, 38 (50.7%) reported a history of childhood abuse and the rest did not. Both groups showed a significant improvement in all three outcomes at the end of treatment and at 12-month follow-up. At the end of treatment, a significant inter-group difference was found for reported abstinence (non-abused group, 39.3% vs abused, 12.9%; p < 0.05). At 12-month follow-up, significant inter-group differences were observed for all treatment outcomes, with superior outcomes being found for the non-abused group, including a higher proportion of women with reported abstinence (55.6% vs 13.3%; p < 0.01). CONCLUSION: The present findings suggest that an evaluation of a possible history of childhood abuse is warranted in all women seeking treatment for AUD, irrespective of social stability. In terms of clinical practice, the results suggest that additional interventions may be warranted in this population.

AIMS: To evaluate the long-term treatment outcome (up to 5 years) with respect to different drinking goals of patients. METHODS: Alcohol-dependent individuals (n = 349) were recruited from three alcohol treatment units. They were interviewed using the Addiction Severity Index (ASI). They were sub-grouped according to their goal at treatment entry: abstinence, low- risk drinking and no decided goal. RESULTS: Patients with abstinence as a goal at treatment entry reported at 2.5 years follow-up a higher abstinence rate, a more pronounced reduction in alcohol consumption, reduction in total number of DSM-IV criteria, higher frequency of low-risk drinking and fewer diagnoses of alcohol dependence compared to the groups who had low risk drinking as a goal or no decided goal. This improvement remained basically unchanged in all three groups at 5 years follow-up, suggesting long-term stability after the treatment interventions. CONCLUSIONS: The findings suggest that: (1) alcohol-dependent patients who have abstinence as their own drinking goal have a more favorable treatment outcome than those who have low-risk drinking as a goal or no decided goal. (2) Abstinence as a drinking goal should be considered for those who have a longer duration (for example more than 10 years) of their alcohol-related problems. (3) Patients who have no decided goal should be recommended abstinence as a drinking goal.

The aim of this study was to predict alcohol inebriation and mental health (internalizing and externalizing problems plus well-being), and potential gender-specific patterns among young adolescents, by a biopsychosocial model of personality traits. Self-reported data from 853 adolescents (479 girls) in Sweden, aged 13-15â¯years, from the Longitudinal Research on Development In Adolescence (LoRDIA) program were used. Predictions from personality to inebriation and mediating effects of mental health were estimated by means of logistic regression and generalized structural equation modelling. Separated gender analyses were performed throughout the study to reveal potential gender-specific patterns. Externalizing problems, Novelty Seeking and Cooperativeness had independent effects on alcohol inebriation for both genders as well as Harm Avoidance among girls and Internalizing problems among boys. Novelty Seeking and Self-Directedness had indirect effects through externalizing problems and Harm Avoidance and Self-Directedness had indirect effects through internalizing problems for boys. Self-directedness showed an indirect effect through externalizing problems for girls. The combination of an immature character (low Self-directedness and Cooperativeness) with an extreme temperament profile (high Novelty Seeking and low Harm Avoidance) was a predictor of inebriation across gender, both directly and indirectly through mental health. This study contributes with valuable information about gender-specific considerations when developing and conducting preventative interventions targeting psychological risk and resilience factors for early alcohol inebriation among young adolescents.

School absenteeism is a potent predictor of academic failure. Maltreated adolescents have been found to be more absent from school compared to their peers. However, it is scarcely studied in what degree a general population of students with high levels of school absenteeism has been exposed to child maltreatment. Furthermore, it is not known if maltreated school-absentees have specific characteristics compared to not-maltreated absentees. In this article, the first objective was to present and compare the prevalence of six types of child maltreatment in a general population of high school students reporting no, moderate or excessive absenteeism. The second objective was to compare maltreated and not-maltreated students who report absenteeism in respect to mental health, perceived school environment and peer victimization in school. Data from 667 girls and 649 boys (mean age 14.3) was used from the longitudinal multidisciplinary research program LoRDIA (Longitudinal Research on Development In Adolescence). Data was collected via self-report questionnaires in classroom settings. All six types of child maltreatment were overrepresented among absentees. Roughly 25% of absentees reported one subtype of maltreatment (16% in the total population) and a mean of 22% of absentees reported two or more types of maltreatment (11% in the total population). Maltreated absentees reported more mental health problems, personal harassment and worse relationship with their teachers than not-maltreated absentees. There might be specific correlates of school absenteeism among maltreated adolescents and professionals involved in preventing school-absenteeism should be made aware of the relationship between maltreatment and absenteeism.

AIMS: To investigate the influence of the A1 allele of the TAQ1A polymorphism in the dopamine D2 receptor (DRD2) gene region on mortality in adult individuals with alcohol dependence. METHODS: The study sample consisted of 359 alcohol-dependent individuals treated for severe alcohol withdrawal symptoms in 1997. Years of survival was studied in an 18-year follow-up. In the analyses, gender and age were controlled for. RESULTS: At the 18-year follow-up, 53% individuals had deceased. The analyses showed that older age (P < 0.001), male gender (P < 0.05) and carrying the A1 allele (P < 0.01) all significantly and independently contributed to shorten years of survival. Among the deceased individuals, the genotype A1+ was the only significant contributor to shorten years of survival. CONCLUSIONS: An important contribution of the present study is that in alcohol dependence the Taq1A1 allele of the DRD2 gene region is a risk factor for premature death of similar importance as the well-known risk factors of age and gender. SHORT SUMMARY: We investigated the influence of A1 allele of the TAQ1A polymorphism in DRD2 receptor gene region on mortality in alcohol-dependent individuals in an 18-year follow-up. Age, gender and the A1 allele contributed to shorten years of survival. Among the deceased, the A1+ was the only contributor to shorten years of survival.

AIMS: The influence of tobacco use in alcohol-dependent individuals is not well understood, especially the role of snuffing, which is common in Northern Europe. The aim was therefore to investigate the influence of smoking and snuffing on the progression, severity and treatment outcome in alcohol-dependent individuals. The hypotheses were that concomitant tobacco use (i.e. smoking or snuffing) would enhance the progression and severity of alcohol dependence and be less beneficial for treatment outcome, relative to tobacco non-users. METHODS: Alcohol-dependent individuals (n = 347) were recruited from three treatment units specialized in alcohol use disorders. Participants were interviewed about their current and past alcohol and tobacco use at treatment entry and at a follow-up interview 2.5 years thereafter. RESULTS: The tobacco users (smokers and snuffers) had an earlier alcohol debut compared to the tobacco never-users. Snuffers reported regular alcohol consumption and inebriation at an earlier age in contrast to smokers and tobacco never-users. There were no difference between the groups regarding treatment outcome. CONCLUSIONS: This study highlights the importance of studying not only the influence of smoking but also of snuffing on the progression, severity and treatment outcome in individuals with alcohol dependence.

BACKGROUND: Alcohol-dependent patients have different treatment goals when entering treatment. Furthermore, different treatment settings advocate different treatment goals. Earlier studies have pointed out that treatment goal is important for treatment outcome, both in the treatment setting as well as in the patients themselves. However, to our knowledge, no study has so far investigated the interaction between patient's goal and the goal of the treatment setting. The aim of the study was therefore to study the interaction between these 2 factors on treatment outcome. METHODS: Patients' (n = 201) goals from 2 treatment settings-one that had an abstinence-oriented goal and one with a low-risk drinking goal-were investigated. The patients were followed up 2.5 years after treatment entry and effectiveness of congruent treatment goals on treatment outcome was investigated. RESULTS: There was no significant association between congruent goals and treatment outcomes (p = 0.060). However, when comparing the effectiveness of congruent treatment goal between the 2 treatment settings, the abstinence-oriented treatment setting was significantly more effective (p < 0.01). CONCLUSIONS: The major finding was that there appeared to be no association between congruence itself and treatment outcome. On the other hand, we found that the treatment outcome was more successful if the patient as well as the treatment setting had abstinence as a goal (i.e., congruent goals of abstinence).

BACKGROUND: Reduced central serotonergic neurotransmission has been demonstrated in individuals with excessive alcohol consumption and/or alcohol dependence. Childhood maltreatment has also been found to have a negative impact on central serotonergic neurotransmission. The aim of this study was to evaluate the impact of childhood maltreatment on central serotonergic dysfunction in alcohol-dependent individuals. METHODS: Adult men with a diagnosis of alcohol dependence (n = 18) were recruited from outpatient treatment units for alcoholism. Central serotonergic neurotransmission was assessed by a neuroendocrine method, that is, the prolactin (PRL) response to the selective 5-HT reuptake inhibitor citalopram. Childhood maltreatment was assessed retrospectively by the Childhood Trauma Questionnaire. RESULTS: Alcohol-dependent individuals with childhood experience of emotional abuse had significantly lower PRL response compared with those without such abuse (3 ± 5 and 64 ± 24 mU/l, respectively; t = 6.51, p < 0.001). Among those who reported childhood emotional abuse, 4 of 7 individuals had flat PRL responses in comparison with none in those with no report of such abuse (p < 0.01). CONCLUSIONS: This is the first study to show that self-reported childhood maltreatment, in particular emotional abuse, in male alcohol-dependent individuals is associated with a quite dramatic (more than 90%) reduction in central serotonergic neurotransmission. It should, however, be noted that the number of individuals is relatively small, and the results should therefore be considered as preliminary.

BACKGROUND: Alcohol dependence has been associated with reduced function of serotonin, dopamine as well as noradrenaline activities in several neuroendocrine studies. To our knowledge, there is, however, no study investigating all these 3 systems with the use of neuroendocrine methods in one and the same alcohol-dependent individual. METHODS: Alcohol-dependent individuals (n = 42) and controls (n = 28) participated in the neuroendocrine test series. Central serotonergic neurotransmission was assessed by the prolactin (PRL) response to citalopram (CIT). The postsynaptic DRD2 function was measured by the growth hormone (GH) response to apomorphine (APO) and the postsynaptic α2-adrenoceptor function by GH response to clonidine (CLON). RESULTS: In the alcohol-dependent individuals, the PRL concentrations were significantly lower at the time points 240 minutes and 300 minutes after CIT administration and mean delta PRL value was significantly reduced by 45% in comparison with controls. There were no significant differences in APO-GH and CLON-GH concentrations at any time points or in mean delta GH values between the groups. An impaired monoaminergic profile, including all 3 systems, was significantly more frequent in alcohol-dependent individuals than controls (43% vs. 6% respectively). CONCLUSIONS: The monoaminergic dysfunction was restricted to an impairment of the serotonergic system, suggesting that this system is especially vulnerable to long-term and excessive alcohol consumption. Moreover, impaired monoaminergic profiles, including low responses in 2 or 3 systems, were more frequently observed in alcohol-dependent individuals than in controls. Such impaired profiles may be of clinical importance, but further studies are needed.

Components of the brain reward system, i.e. the mesolimbic dopamine, laterodorsal cholinergic and ghrelin signaling systems, have been implicated in alcohol reward in preclinical studies. Genetic variants of these systems have previously been linked to alcohol dependence. Here, we genotyped 31 single nucleotide polymorphisms (SNPs): 1 SNP in the dopamine D2 receptor (DRD2) gene, 20 SNPs in 5 different nicotinic acetylcholine receptor subunit (CHRN*) genes, and 10 SNPs in the genes encoding pro-ghrelin (GHRL) and its receptor (GHSR), in a pilot study of type 1 alcoholics (n = 84) and healthy controls (n = 32). These individuals were characterized using the Temperament and Character Inventory. None of the SNPs were associated with risk of alcohol dependence in this population. The GG genotype of SNP rs13261190 in the CHRNB3 was associated with increased novelty seeking, while SNPs of the ghrelin signaling system were associated with decreased self-directedness (AA of rs495225, GHSR) and alterations in self-transcendence (AA of both rs42451 and rs35680, GHRL). In conclusion, this pilot study suggests that reward-related genes are associated with altered personality scores in type 1 alcohol dependence, which warrants future studies of these associations in larger study samples.

AIMS: The TaqIA polymorphism of the dopamine D2 receptor (DRD2) gene has been extensively studied in relation to alcoholism, and the TaqI A1 allele appears to be over-represented in alcohol-dependent individuals. In a recent study, this allele has also been associated with a highly increased mortality rate in alcohol-dependent individuals. In the present study, we investigated whether the TaqI A1 allele of the DRD2 gene region was associated with a higher relapse rate in alcohol-dependent individuals. METHODS: Adult women (n = 10) and men (n = 40) with a diagnosis of alcohol-dependence were recruited from two Swedish 12-step treatment units for alcoholism. Subjects were genotyped for the TaqIA polymorphism. On average, 1½ year after the end of the treatment program, subjects were re-interviewed by using the alcohol-related items from the Addiction Severity Index follow-up version. RESULTS: Thirty-three (66%) subjects self-reported relapse and 17 (34%) abstinence during the follow-up period. Thirty-sex percent (18/50) were carriers of the A1 allele of the DRD2 gene region, and 64% (32/50) were non-carriers. Among the carriers of the A1 allele, 89% (16/18) reported relapse in contrast to 53% (17/32) in the non-carriers (P = 0.01; odds ratio = 7.1). CONCLUSION: The present study is, to our knowledge, the first report of an association between the TaqI A1 allele and a substantially increased relapse rate. It should be emphasized that the number of subjects is relatively small, and this investigation should therefore be considered as a pilot study.

The existence of an "addictive" personality has been extensively debated. The current study investigated personality in male individuals with excessive alcohol consumption (n=100) in comparison to a population-based control group (n=131). The individuals with excessive alcohol consumption were recruited by advertisements in a regional daily newspaper and controls from a population based Swedish Twin Registry. Personality was assessed by the Karolinska Scales of Personality (KSP). Comparisons were made with normative data. Furthermore, by using a multivariate projection-based approach (Principal Component Analysis; PCA), hidden structures of traits and possible relationships among the individuals with excessive consumption and the controls was investigated. The individuals with excessive alcohol consumption as well as the controls had mean values within the normative range in all scales of the KSP. Moreover, the PCA analysis revealed no systematic between-group separation. Taken together, this result demonstrates that male individuals with excessive alcohol consumption do not have a personality different from that of a general population, which supports the notion of no "addictive personality".

AIMS: Because the TAQ1 A1 allele may be associated with alcohol-related medical illnesses, and medical illnesses in alcohol-dependent individuals are associated with increased mortality, we test the hypothesis that the TAQ1 A1 allele of the DRD2 gene is associated with increased mortality in alcohol-dependent individuals. METHODS: Following an index treatment episode, a 10-year follow-up study in 366 alcohol-dependent individuals was performed. The TAQ1 A1/A2 DRD2 genotype and allele frequencies were compared between those deceased and those still living at the 10-year point. In addition, the genotype and allele frequencies of these alcohol-dependent individuals were compared to that in 578 control subjects. RESULTS: The prevalence of the A1 allele differed between the deceased and living patients and the controls: 47% of the deceased were A1+, compared to 37% of the living patients and 32% of the controls. The frequency of the TAQ1 A1/A2 genotype also differed between the groups. Thus, 43% had the A1/A2 genotype in comparison with 32% in the living patients and 29% in the controls. The TAQ 1 A1 allele frequency differed between the groups. The frequency of A1 allele was 25% in the deceased patients compared to 21% in the living patients and 17% in the controls. CONCLUSION: The TAQ I A1 allele of the DRD2 gene (or DRD2 gene region) was associated with increased mortality over a 10-year period in alcohol-dependent individuals.

Serum gamma-glutamyltransferase (GGT) is recommended as a marker for alcohol use disorders by the Swedish National Guidelines for Addiction, although it has a low sensitivity and specificity. GGT is inexpensive and easily accessible but additional knowledge is required on how to use the marker in patients with various levels of alcohol intake. Levels of GGT were obtained from 37 male social drinkers (< 100 grams pure alcohol weekly) and 18 former alcohol-dependent males with long-term (6 +/- 5 years) abstinence. Reproducibility was calculated through repeated blood samplings. Mean serum activity of GGT, in former alcohol-dependent males, was 0.26 microkat/L with an intra-class correlation coefficient of 0.85. In social drinkers, these figures were 0.34 microkat/L and 0.92, respectively. In treatment of males, with the goal of abstinence, upper reference limit is suggested to be 0.40 microkat/L. Goals of non-harmful drinking (< 100 grams weekly) suggest higher limits (0.62 microkat/L). Thirty percent increase of GGT should be suggestive of relapse.

AIMS: In several studies, possible risk factors/predictors for severe alcohol withdrawal syndrome (AWS), i.e. delirium tremens (DT) and/or seizures, have been investigated. We have recently observed that low blood platelet count could be such a risk factor/predictor. We therefore investigated whether such an association could be found using a large number of alcohol-dependent individuals (n = 334). METHODS: This study is a retrospectively conducted cohort study based on data from female and male patients (>20 years of age), consecutively admitted to an alcohol treatment unit. The individuals had to fulfil the discharge diagnoses alcohol dependence and alcohol withdrawal syndrome according to DSM-IV. RESULTS: During the treatment period, 3% of the patients developed DT, 2% seizures and none had co-occurrence of both conditions. Among those with DT, a higher proportion had thrombocytopenia. Those with seizures had lower blood platelet count and a higher proportion of them had thrombocytopenia. The sensitivity and specificity of thrombocytopenia for the development of DT during the treatment period was 70% and 69%, respectively. The positive predictive value (PPV) was 6% and the negative predictive value (NPV) was 99%. For the development of seizures, the figure for sensitivity was 75% and for specificity 69%. The figures for PPV and NPV were similar as those for the development of DT. CONCLUSIONS: Thrombocytopenia is more frequent in patients who develop severe AWS (DT or seizures). The findings, including the high NPV of thrombocytopenia, must be interpreted with caution due to the small number of patients who developed AWS. Further studies replicating the present finding are therefore needed before the clinical usefulness can be considered.
