A pilot study on the feasibility and acceptability of a text message-based aftercare treatment programme among alcohol outpatients.

AIMS: To test the feasibility, acceptability and initial effectiveness of a text message-based aftercare treatment programme among alcohol outpatients. METHODS: Clients treated for alcohol use disorders from three Swiss outpatient alcohol treatment centres were invited by their counsellors to participate in a study testing an interactive aftercare programme employing the use of text messages and personal phone calls. Fifty study participants were randomly assigned to either the 6-month aftercare programme (n = 25) or treatment as usual (n = 25). The intervention consisted of (a) monitoring of self-selected drinking goals at regular intervals, (b) motivational text messages to stick to self-selected drinking goals and (c) proactive telephone calls from counsellors when participants neglected to stick to their drinking goals or expressed a need for support. Follow-up interviews were conducted 6 months after randomization. RESULTS: Throughout the programme, participants received a total of 421 text message prompts. Out of these, participants provided valid replies to 371 (88.1%) within 48 h. Out of the 25 participants in the intervention group, 11 (44.0%) sent at least one call-for-help reply. Based on complete case data, at risk alcohol use at follow-up was 41.7% in the control group and 28.6% in the intervention group (OR = 0.56, 95% CI = 0.16-1.95, P = 0.36). CONCLUSIONS: The interactive low-intensive aftercare programme was well accepted by the participants. Testing its efficacy within an adequately powered randomized controlled trial might be reasonable.

A surveillance tool using mobile phone short message service to reduce alcohol consumption among alcohol-dependent patients.

BACKGROUND: In public health settings, short message service (SMS) appears to be a promising low-cost modality for reducing alcohol consumption. Here, we test a simple interactive SMS-based helpline with detoxified alcohol-dependent patients to extend findings to curative settings. METHODS: This controlled, prospective, 2-group before-after block-assignment, open pilot study tested the feasibility and efficacy of an 8-week outpatient interactive mobile phone SMS intervention (n = 42) against treatment as usual (TAU; n = 38) after inpatient detoxification. Patients were asked whether they needed any help via an automatically generated text message twice a week. A therapist called the individual back when notified. Alcohol consumption was assessed using the telephone version of Form-90 4 and 8 weeks after discharge from inpatient detoxification. The primary end point was defined as attaining low-risk consumption (males ≤30 g or 3.75 units per drinking day (DDD); females ≤20 g or 2.5 units per DDD) 8 weeks after discharge. Missing data were replaced by multiple imputation. RESULTS: Among all messages sent, 20.5% were followed by a phone call. Feasibility and acceptability were good, as indicated by successful implementation of the SMS procedure and the rapid inclusion of patients. Adherence was satisfactory with 57.14% of the participants replying to at least 50% of the prompts. Patients reported a typical preadmission DDD of 281.25 ± 244.61 g. In the SMS group, 55.7% of 42 patients, and 40% of 38 patients in the TAU group, achieved low-risk consumption (risk diff: 0.16; 95% CI -0.06 to 0.37; p = 0.122). CONCLUSIONS: In detoxified alcohol-dependent patients, relapse prevention based on SMS was well received and implemented efficiently and rapidly. An adequately powered multicenter study is currently being conducted to test the nonsignificant but encouraging findings of this exploratory study with more rigorous trial methods (ISRCTN78350716).

Associations between the oxytocin receptor gene (OXTR) and "mind-reading" in humans--an exploratory study.

BACKGROUND/AIMS: The application of intranasal oxytocin enhances facial emotion recognition in normal subjects and in subjects with autism spectrum disorders (ASD). In addition, various features of social cognition have been associated with variants of the oxytocin receptor gene (OXTR). Therefore, we tested for associations between mind-reading, a measure for social recognition and OXTR polymorphisms. METHODS: 76 healthy adolescents and young adults were tested for associations between OXTR rs53576, rs2254298, rs2228485 and mind-reading using the "Reading the Mind in the Eyes Test" (RMET). RESULTS: After Bonferroni correction for multiple comparisons, rs2228485 was associated with the number of incorrect answers when subjects evaluated male faces (P =0.000639). There were also associations between OXTR rs53576, rs2254298 and rs2228485 and other RMET dimensions according to P <0.05 (uncorrected). CONCLUSION: This study adds further evidence to the hypothesis that genetic variations in the OXTR modulate mind-reading and social behaviour.

The inverse link between genetic risk for schizophrenia and migraine through NMDA (N-methyl-D-aspartate) receptor activation via D-serine.

Schizophrenia has a considerable genetic background. Epidemiological studies suggest an inverse clinical association between schizophrenia and migraine. However, it is unclear to what extent this inverse comorbidity can be explained by genetic mechanisms or by schizophrenia-related behavioral factors. For both disorders hypotheses of glutamate N-methyl-D-aspartate (NMDA) receptor dysfunction have been developed in the past. We hypothesized that both conditions share common genetic factors with inverse effects, primary in the glutamatergic system and genes involved in NMDA activation. Data from the population based Study of Health in Pomerania (N=3973) were used. Based on the results from the recent genome-wide association study for schizophrenia, we calculated polygenic scores (PRS) for subsets of SNPs with different p-value cutoffs and for biological sub-entities. These scores were tested for an association of distinct biological pathways with migraine. The PRS for schizophrenia was inversely associated with migraine in our sample. This association was exclusively based on the genome-wide hits and on single nucleotide polymorphisms near or within genes encoding proteins involved in glutamatergic neurotransmission. This association could be attributed to a single intronic variant rs4523957 in SRR encoding serine-racemase. Additional expression quantitative trait loci analyses of functional variants in SRR and gene-by-gene interaction analyses further supported the validity of this finding. SRR represents the rate limiting enzyme for the synthesis of D-serine, an important co-agonist of the NMDA receptor. According to our results, a decreased versus increased activation of NMDA receptors may play a role in the etiology of schizophrenia, as well as in migraine.

Changes in the perception of alcohol-related stigma in Germany over the last two decades.

BACKGROUND: Alcohol dependence is a severely stigmatized disorder. Perceived stigma may deter help-seeking and is associated with higher co-morbidity and self-stigma in persons with alcohol dependence. We assess changes in the perception of alcohol-related stigma over 21 years in the general population. METHODS: Two representative population surveys using identical methodology were conducted in Germany in 1990 and 2011 (n=1022 and n=967), eliciting the perceived discrimination and devaluation of someone with a history of alcohol problems as measured with an adoption of Link's Perceived Discrimination and Devaluation Scale (aPDDS), and perceived negative stereotypes of an "alcoholic." RESULTS: Both on item level and using factor scores, attitudes changed significantly between 1990 and 2011. Perceived discrimination and devaluation of someone with a history of alcohol dependence decreased considerably by 0.44 standard deviations (SD). Perceived negative stereotypes related to unpredictability of an "alcoholic" increased slightly by 0.15 SD, while perceived stereotypes related to strangeness decreased (-0.23 SD). CONCLUSIONS: Our findings suggest that particularly the image of someone who has received treatment for alcohol dependence has improved in Germany. This parallels increasing acceptance of professional treatment for alcohol dependence among the general population over the last twenty years, and contrasts with overall unchanged negative attitudes toward persons who actually suffer from alcohol problems.

Associations between the oxytocin receptor gene (OXTR) and affect, loneliness and intelligence in normal subjects.

Associations of oxytocin receptor gene (OXTR) variants and autism spectrum disorders (ASD) have been reported in earlier studies; in one of the studies associations with IQ and daily living skills were found additionally. Variations of the oxytocin receptor gene might also regulate affect, attachment and separation beyond the diagnostic borders of autism. We tested hypotheses of associations between positive and negative affects and social and emotional loneliness (285 adults), IQ (117 adolescents) and polymorphisms of the oxytocin receptor gene (OXTR rs53576, rs2254298 and rs2228485) in normal subjects. Individuals with the oxytocin OXTR rs53576 A/A genotype showed lower positive affect scores (F=5.532, df=1; p=0.019). This effect was restricted to males (F=13.098, df=1; p=0.00047). Haplotypes constructed with the three markers were associated with positive affect (p=0.0012), negative affect (p<0.0001) and emotional loneliness (p<0.0001). Non-verbal intelligence was significantly reduced in rs53576 A/A adolescents (T=2.247, p=0.027). Our findings support a role for the oxytocin receptor haplotypes in the generation of affectivity, emotional loneliness and IQ.
