Effectiveness of a self-help guide during a temporary alcohol abstinence challenge: a randomized controlled trial.

BACKGROUND: The popularity of temporary abstinence challenges (TACs) concerning alcohol consumption is increasing. Support is found to be essential for participants to help them get through a challenge. This study aimed to evaluate the additional effect of a self-help guide, based on health behaviour theories and behaviour change techniques, on (i) successful completion of a TAC and (ii) changes in drinking refusal self-efficacy (DRSE), behavioural automaticity, craving, and alcohol consumption. METHODS: A randomized controlled trial was performed (OSF registries: OSF.IO/B95VU). NoThanks participants received a questionnaire before the TAC (T0) and 8 months after the TAC (T1). Out of a subgroup of 1308 respondents who were interested in additional support, 652 were randomly assigned to receive the guide (experimental group), and 656 did not receive any additional support (control group). Logistic regressions and (generalized) linear mixed model analyses were used. RESULTS: After 8 months, all participants showed a significant decrease in behavioural automaticity, craving, and alcohol consumption, irrespective of group assignment. No significant changes were observed in the DRSE. This degree of change over time in behavioural automaticity, craving, and alcohol consumption did not differ between the experimental and control group. Sensitivity analyses with participants in the experimental group, who differed in exposure to the guide, did not show differences either. CONCLUSION: The self-help guide, and how it was designed, added no value to the TAC. Future research should focus on more bottom-up, customized support and explore what (different subgroups of) participants think they need as extra support during a TAC.

Towards a New Definition of the Typical Day in the Alcohol Use Disorder Identification Test-Consumption.

INTRODUCTION: The standard screening instrument for alcohol problems in the current primary care, the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C), contains a question about alcohol consumption "on a typical day." Since this is a term that leaves room for multiple interpretations and the differences between alcohol consumption on weekends and weekdays are not taken into account, this study examines whether the latter distinction improves the prediction validity of the screening instrument. METHODS: A subgroup of 852 participants of the Dutch version of Dry January ("NoThanks") 2022 got the annual "NoThanks" survey, including questions about their alcohol consumption on weekends and weekdays, and the original ten AUDIT questions. The full AUDIT was used as golden standard. Sensitivity, specificity, and receiver operating characteristic curves were calculated for the original and different versions of the AUDIT-C. RESULTS: Of all participants, 67 percent were hazardous drinkers (AUDIT ≥8) and 27 percent were harmful drinkers (AUDIT ≥16). For the original AUDIT-C, the cut-off score with the most balanced combination of sensitivity and specificity for hazardous drinking in men was 7 and in women was 6. For harmful drinking, this was 8 and 7, respectively. Certain versions performed equally well as the original. For harmful drinkers, the highest area under the receiver operating characteristic curve (AUROC) was 0.814 and 0.866 for the original AUDIT-C, for men and women, respectively. Only for hazardous drinking men, the AUDIT-C with weekend day (AUROC = 0.887) performed slightly better than the original. CONCLUSION: Distinguishing weekend- and weekday alcohol consumption in the AUDIT-C does not lead to better predictions of problematic alcohol use. However, the distinction between weekends and weekdays provides more detailed information for healthcare professionals and can be used without having to compromise too much on validity.

Examining preconditions for integrated care: a comparative social network analysis of the structure and dynamics of strong relations in child service networks.

BACKGROUND: To help ensure that children and families get the right support and services at the right time, strong and stable relationships between various child service organizations are vital. Moreover, strong and stable relationships and a key network position for gatekeepers are important preconditions for interprofessional collaboration, the timely and appropriate referral of clients, and improved health outcomes. Gatekeepers are organizations that have specific legal authorizations regarding client referral. However, it is largely unclear how strong relations in child service networks are structured, whether the gatekeepers have strong and stable relationships, and what the critical relations in the overall structure are. The aim of this study is to explore these preconditions for integrated care by examining the internal structure and dynamics of strong relations. METHODS: A comparative case study approach and social network analysis of three inter-organizational networks consisting of 65 to 135 organizations within the Dutch child service system. Multiple network measures (number of active organizations, isolates, relations, average degree centrality, Lambda sets) were used to examine the strong relation structure and dynamics of the networks. Ucinet was used to analyze the data, with use of the statistical test: Quadratic Assignment Procedure. Visone was used to visualize the graphs of the networks. RESULTS: This study shows that more than 80% of the organizations in the networks have strong relations. A striking finding is the extremely high number of strong relations that gatekeepers need to maintain. Moreover, the results show that the most important gatekeepers have key positions, and their strong relations are relatively stable. By contrast, considering the whole network, we also found a considerable measure of instability in strong relationships, which means that child service networks must cope with major internal dynamics. CONCLUSIONS: Our study addressed crucial preconditions for integrated care. The extremely high number of strong relations that particularly gatekeepers need to build and maintain, in combination with the considerable instability of strong relations considering the whole network, is a serious point of concern that need to be managed, in order to enable child service networks to improve internal coordination and integration of service delivery.

HIGHLIGHTS: More than 80% of the organizations in the network has strong relations.Gatekeepers need to maintain an extremely high number of strong relations.Child service networks need to cope with major internal dynamics.These insights offer leads for optimizing how a network functions.

Stakeholder perspectives on primary school pupils and sickness absence - exploring opportunities and challenges.

School absenteeism and its underlying causes can have negative effects on the cognitive, psychosocial and health development of a child. Research in primary education shows high rates of sickness absence. Many stakeholders are involved in addressing school absenteeism, including primary school professionals, child and youth healthcare physicians, school attendance officers and parents. This study explores these stakeholders' perspectives, their approaches and what they envisage to be necessary in order to improve. It also aims to unveil opportunities and challenges in addressing sickness absence among primary school pupils. Qualitative research was performed with six semi-structured focus group interviews and involving 27 participants from the West-Brabant and Amsterdam regions of the Netherlands. Thematic analysis was used. The overarching theme was aiming for the child's wellbeing. Each focus group interview started with low awareness of sickness absence as a threat to this wellbeing, but awareness grew during the interviews. The participating stakeholders regarded problematic sickness absence as complex due to a wide variety of causes, and felt that each other's expertise was necessary to reduce sickness absence. Schools registered absence, but only occasionally used planned steps; they based the identification of problematic sickness on gut feeling rather than any agreed-upon criteria. To be able to systematically address sickness absence and thus improve the wellbeing of children, stakeholders felt the need for a clearly structured approach, including monitoring of sickness absence of all pupils, identifying problematic absence and promoting collaboration with other stakeholders. An approach should allow for tailoring solutions to the individual child.

Intersectoral collaboration at a decentralized level: information flows in child welfare and healthcare networks.

BACKGROUND: As needs of families with social and behavioral health problems often exceed the expertise and possibilities of a single professional, service or organization, cross-service collaboration is indispensable to adequately meeting those needs. Despite the progressive focus on organizing integrated care, service fragmentation and service duplication remain persistent problems in child welfare and healthcare service delivery systems. A crucial factor to overcome these problems is information exchange between organizations. This study explores and compares the development over time of structures of information exchange in networks, concerning both material and knowledge-based information. METHODS: A comparative case study and social network analysis of three inter-organizational networks of child welfare and healthcare services in different-sized municipalities in the Netherlands. The research population consisted of organizations from various sectors participating in the networks. Data were collected at two moments in time with a mixed method: semi-structured interviews with network managers and an online questionnaire for all network members. Density and degree centralization were used to examine the information exchange structures. Ucinet was used to analyze the data, with use of the statistical tests: Compare Density Procedure and Quadratic Assignment Procedure. RESULTS: This study shows that different structures of information exchange can be distinguished, concerning both material and knowledge-based information. The overall connectedness of the studied structures of the networks are quite similar, but the way in which the involvement is structured turns out to be different between the networks. Over time, the overall connectedness of those structures appears to be stable, but the internal dynamics reveals a major change in relationships between organizations in the networks. CONCLUSIONS: Our study yields empirical evidence for the existence of and the differences between structures and dynamics of both material and knowledge-based information exchange relationships. With a loss of more than a half of the relations in a year, the relationships between the organizations in the network are not very stable over time. The contrast between major internal dynamics and the stable overall connectedness is an important point of concern for network managers and public officials, since this impermanence of relations means that long-term integrated care cannot be guaranteed.

Survey of intention among public health nurses in providing solution-focused parenting support.

OBJECTIVE: Parenting support has shifted from a problem-focused to a strengths-based solution-focused approach. This study surveyed public health nurses to explain their intention to provide solution-focused parenting support in their practice. DESIGN: The design of this study was cross-sectional. SAMPLE: The initial sample included 781 public health nurses who were employed with various youth healthcare organizations in the Netherlands. MEASUREMENTS: Based on the Theory of Planned Behavior, a questionnaire was developed and administered to measure (a) behavioral, normative, and control beliefs, (b) attitudes, subjective norm, and perceived behavioral control, and (c) intention. The data were subjected to structural equation modeling. RESULTS: A total of 449 (57.5%) public health nurses completed questionnaires. Associations as indicated by the Theory of Planned Behavior were confirmed with the exception of that between perceived behavioral control and intention. Statistically significant paths and correlations were added. The final model accounted for 53% of the variance in the intention to perform solution-focused parenting support. CONCLUSIONS: In this study, public health nurses strongly intended to provide solution-focused parenting support, thus indicating their acceptance of the approach. Their intention was predominantly associated with subjective norm.

Line managers' hiring intentions regarding people with mental health problems: a cross-sectional study on workplace stigma.

OBJECTIVES: Stigma may negatively affect line managers' intention to hire people with mental health problems (MHP). This study aims to evaluate line managers' knowledge and attitudes concerning job applicants with MHP, and to assess which factors are associated with the intention (not) to hire an applicant with MHP. METHODS: A sample of Dutch line managers (N=670) filled out a questionnaire on their knowledge, attitudes and experiences concerning applicants/employees with MHP. Descriptive analyses and multiple regression analyses were used. RESULTS: The majority (64%) was reluctant to hire a job applicant with MHP, despite the fact that only 7% had negative and 52% had positive personal experiences with such employees. Thirty per cent were reluctant to hire an applicant if they knew the applicant had past MHP. Associated with higher reluctance to hire an applicant with MHP were the concerns that it will lead to long-term sickness absence (ß (95% CI)=0.39 (0.23 to 0.55)), that the employee cannot handle the work (ß (95% CI)=0.16 (0.00 to 0.33)) that one cannot count on the employee (ß (95% CI)=0.41 (0.23 to 0.58)) and higher manager education level (ß (95% CI)=0.25 (0.05 to 0.44)). Conversely, associated with positive hiring intentions was being in favour of diversity and/or inclusive enterprise (ß(95% CI)=-0.64 (-0.87 to -0.41)). CONCLUSIONS: As the majority of managers were reluctant to hire applicants with MHP, and even 30% were reluctant to hire applicants who had past MHP, these findings have major implications for social inclusion in the Netherlands, where about 75% of employees would disclose MHP at work.

The prevalence of sickness absence among primary school pupils - reason to be worried?

BACKGROUND: Absence from school can lead to lower educational achievement and poor health. Little is known about school absence in primary education. This study's first aim was to examine the prevalence of school absence in primary schools and differing types of absence, including sickness absence. The second aim was to determine which pupil characteristics and types of absence were associated with extensive sickness absence. METHODS: The school absence registries for the school year 2015-2016 were analysed retrospectively in eight mainstream primary schools with 2216 pupils, and six schools for special primary education with 1000 pupils in the West-Brabant region of the Netherlands. Descriptive analyses, χ2-tests, Mann-Whitney U tests and logistic regression analyses were performed. RESULTS: The one-year prevalence of school absence was 85% in mainstream primary schools and 79% in special schools. Sickness absence was the most prevalent type of absence, occurring in 75 and 71% of pupils, respectively The prevalence of extensive sickness absence was 13 and 23%, respectively. In mainstream schools, extensive sickness absence was associated with a young age, low parental educational level, more doctor's visits and unauthorised absence, and in special schools with more doctor's visits, other authorised absence, tardiness and unauthorised absence. CONCLUSIONS: The prevalence of extensive sickness absence was high, and as this was associated with other types of absence, these pupils missed even more days of school. Public health research, policy and practice should address sickness absence among primary school pupils, to prevent adverse effects on children's development.

Commitment Lotteries Promote Physical Activity Among Overweight Adults-A Cluster Randomized Trial.

Background: The World Health Organization has identified physical inactivity as the fourth leading risk factor for global mortality. People often intend to engage in physical activity on a regular basis, but have trouble doing so. To realize their health goals, people can voluntarily accept deadlines with consequences that restrict undesired future behaviors (i.e., commitment devices). Purpose: We examined if lottery-based deadlines that leverage regret aversion would help overweight individuals in attaining their goal of attending their gym twice per week. At each deadline a lottery winner was drawn from all participants. The winners were only eligible for their prize if they attained their gym-attendance goals. Importantly, nonattending lottery winners were informed about their forgone prize. The promise of this counterfactual feedback was designed to evoke anticipated regret and emphasize the deadlines. Methods: Six corporate gyms with a total of 163 overweight participants were randomized to one of three arms. We compared (i) weekly short-term lotteries for 13 weeks; (ii) the same short-term lotteries in combination with an additional long-term lottery after 26 weeks; and (iii) a control arm without lotteries. Results: After 13 weeks, participants in the lottery arms attained their attendance goals more often than participants in the control arm. After 26 weeks, we observe a decline in goal attainment in the short-term lottery arm and the highest goal attainment in the long-term lottery arm. Conclusions: With novel applications, the current research adds to a growing body of research that demonstrates the effectiveness of commitment devices in closing the gap between health goals and behavior. Clinical Trial information: This trial is registered in the Dutch Trial Register. Identifier: NTR5559.

E-cigarette and waterpipe use in two adolescent cohorts: cross-sectional and longitudinal associations with conventional cigarette smoking.

Alternative tobacco products are increasing in popularity. An important question is whether their use is associated with or even leads to conventional smoking, but large-scale (European) studies are scarce. In two cohorts of Dutch adolescents (Cohort I n = 6819, mean age = 13.8 SD = 1.1, 48.2% female; Cohort II n = 2758, mean age = 17.3 SD = 1.8, 61.3% female), we investigated use of electronic (e)-cigarettes with nicotine, e-cigarettes without nicotine and waterpipe. Generalized estimating equation modelling was conducted with ever conventional smoking as the dependent variable (0 = no, 1 = yes) and ever alternative tobacco use as the independent variable, correcting for clustering within schools, age, sex and education in both cohorts. In a subsample (n = 2100), the association between alternative tobacco use at baseline and conventional smoking 6 months later was tested, taking into account smoking propensity (based on personality, susceptibility to peer pressure and smoking intentions). Ever use prevalence was 13.7% for e-cigarettes with nicotine, 29.4% for e-cigarettes without nicotine and 22.1% for waterpipe in Cohort I and 12.3, 27.6 and 45.3% respectively in Cohort II. Ever smokers had tried alternative tobacco products more often than never smokers. Among never-smoking adolescents at baseline, alternative tobacco use predicted ever smoking 6 months later (e-cigarettes with nicotine OR 11.90 95% CI 3.36-42.11; e-cigarettes without nicotine OR 5.36 95% CI 2.73-10.52; waterpipe OR 5.36 95% CI 2.78-10.31). This association was strongest for adolescents with a low baseline risk of smoking. Experimenting with alternative tobacco products is common among Dutch youth. Alternative tobacco use predicts (future) smoking, especially among adolescents with a low smoking propensity.

Physical activity after commitment lotteries: examining long-term results in a cluster randomized trial.

To overcome self-control difficulties, people can commit to their health goals by voluntarily accepting deadlines with consequences. In a commitment lottery, the winners are drawn from all participants, but can only claim their prize if they also attained their gym-attendance goals. In a 52-week, three-arm trial across six company gyms, we tested if commitment lotteries with behavioral economic underpinnings would promote physical activity among overweight adults. In previous work, we presented an effective 26-week intervention. In the present paper we analyzed maintenance of goal attainment at 52-week follow-up and the development of weight over time. We compared weight and goal attainment (gym attendance ≥ 2 per week) between three arms that-in the intervention period- consisted of (I) weekly short-term lotteries for 13 weeks; (II) the same short-term lotteries in combination with an additional long-term lottery after 26 weeks; and (III) a control arm without lottery-deadlines. After a successful 26-week intervention, goal attainment declined between weeks 27 and 52 in the long-term lottery arm, but remained higher than in the control group. Goal attainment did not differ between the short-term lottery arm and control arm. Weight declined slightly in all arms in the first 13 weeks of the trial and remained stable from there on. Commitment lotteries can support regular gym attendance up to 52 weeks, but more research is needed to achieve higher levels of maintenance and weight loss.

Emotional responses to behavioral economic incentives for health behavior change.

Many people aim to change their lifestyle, but have trouble acting on their intentions. Behavioral economic incentives and related emotions can support commitment to personal health goals, but the related emotions remain unexplored. In a regret lottery, winners who do not attain their health goals do not get their prize but receive feedback on what their forgone earnings would have been. This counterfactual feedback should provoke anticipated regret and increase commitment to health goals. We explored which emotions were actually expected upon missing out on a prize due to unsuccessful weight loss and which incentive-characteristics influence their likelihood and intensity. Participants reported their expected emotional response after missing out on a prize in one of 12 randomly presented incentive-scenarios, which varied in incentive type, incentive size and deadline distance. Participants primarily reported feeling disappointment, followed by regret. Regret was expected most when losing a lottery prize (vs. a fixed incentive) and intensified with prize size. Multiple features of the participant and the lottery incentive increase the occurrence and intensity of regret. As such, our findings can be helpful in designing behavioral economic incentives that leverage emotions to support health behavior change.

Addressing medical absenteeism in pre-vocational secondary students: effectiveness of a public health intervention, using a quasi-experimental design.

BACKGROUND: Students' health and school absenteeism affect educational level, with adverse effects on their future health. This interdependence is reflected in medical absenteeism. In the Netherlands, a public health intervention has been developed to address medical absenteeism in pre-vocational secondary education. This study aims to investigate the effectiveness of this intervention on students' medical absenteeism, compared to "medical absenteeism policy as usual". METHODS: A quasi-experimental design with an intervention group (493 students) and a control group (445 students) was applied. Multilevel analysis was used to study differences in the development of the level of a student's medical absence over time (after 3 and 12 months). RESULTS: In the intervention group, the level of absenteeism decreased from 8.5 days reported sick in 12 school weeks to 5.7 days after 3 months, and to 4.9 days after 12 months. The number of absence periods fell from 3.9 in 12 school weeks to 2.5 after 3 months, and to 2.2 after 12 months. In the control group, the absence days initially decreased from 9.9 days reported sick in 12 school weeks to 8.4 days after 3 months, after which an increase to 8.9 days was measured. The number of absence periods initially decreased from 4.5 in 12 school weeks to 3.5, after which an increase to 3.7 was measured. The number of absence days per period remained about the same in both groups. CONCLUSIONS: The study provides first indications for the intervention to be effective for Dutch pre-vocational secondary students with increased medical absence rates. The intervention, which consists of personalised management of medical absenteeism by systematic identification of students with extensive medical absenteeism and consistent referral to youth health care physicians, appears to reduce the absence rates more effectively than "medical absenteeism policy as usual". The effectiveness of the intervention is shown primarily by a decrease in the number of periods reported sick.

Effect of an intervention to enhance guideline adherence of occupational physicians on return-to-work self-efficacy in workers sick-listed with common mental disorders.

BACKGROUND: Since a higher level of self-efficacy in common mental disorders is associated with earlier return-to-work (RTW), it is important to know if work related self-efficacy can be increased by occupational health care. The primary aim of this study was to evaluate whether an intervention to enhance guideline adherence of occupational physicians lead to an increase in RTW self-efficacy in workers three months later. The secondary aim was to evaluate whether the intervention modified the association between RTW self-efficacy and return-to-work three months later. METHODS: A total of 66 occupational physicians participated in the study. They were randomized into two groups; the intervention group received a training, the control group did not. The training aimed to enhance adherence to a mental health guideline that contained strategies that are supposed to enhance RTW self-efficacy. In 128 sick-listed workers guided by these occupational physicians, RTW self-efficacy, RTW, and personal, health-related and work-related variables were measured at baseline and three months later. Generalized linear mixed models analysis and linear mixed models analysis were used for the evaluations. RESULTS: In workers whose occupational physicians had received the training RTW self-efficacy increased significantly more than in workers whose occupational physicians had participated in the control group (t = -2.626, p ≤ .05). Higher baseline RTW self-efficacy scores were significantly more often associated with full RTW than with no RTW three months later (OR 2.20, 95 % CI 1.18-4.07), but the intervention did not affect this association. CONCLUSIONS: This study showed that a training to enhance guideline adherence of occupational physicians leads to increased RTW self-efficacy in workers sick-listed with common mental disorders during the first months of sickness absence in a real-life occupational health care setting. This insight is helpful for optimizing the recovery and RTW process, and for understanding the role of RTW self-efficacy in this process. TRIAL REGISTRATION: ISRCTN86605310.

Alcohol segment-specific associations between the quality of the parent-child relationship and adolescent alcohol use.

BACKGROUND: There is much evidence that parents have an influence on the alcohol use of their children. However, in general the relationship is rather weak. A reason for this small association may be due to the fact that adolescents are a heterogeneous group and that, consequently, the association between the quality of the parent-child relationship and alcohol use varies for diverse subgroups, resulting in an overall small effect. In an earlier study we found five different segments for adolescents regarding their attitude towards alcohol. This article reports on a study into the differences between these segments with respect to the quality of the parent-child relationship and parental attitudes to alcohol. Moreover, we examined segment-specific associations of the quality of the parent-child relationship and alcohol use. METHODS: This study used data from a survey held among adolescents aged 12 to 18. A random sample of 59,073 adolescents was drawn from 67 municipalities in the south of the Netherlands. To assign respondents into one of the five segments, a questionnaire of 28 items concerning alcohol and approval from others from the original segmenting study was included in the internet version. Therefore, only the results of the internet version (N = 12,375 adolescents) were analysed. RESULTS: Both the quality of the parent-child relationship and the attitude of the parents towards the drinking behaviour of their children differed between the segments. Significant associations were found between the quality of the parent-child relationship and life-time and recent alcohol use and binge drinking. The interaction between the quality of the parent-child relationship and the segments was only significant for binge drinking. CONCLUSIONS: The quality of the parent-child relationship seemed to be most strongly associated with life-time alcohol use, suggesting that parents appear to play the most important role in the prevention of alcohol use. Moreover, the results showed segment-specific associations between the quality of the parent-child relationship and binge drinking, indicating that the role of parents in heavy drinking is different for the various segments.

Exploring barriers and facilitators to addressing hazardous alcohol use and AUD in mental health services: a qualitative study among Dutch professionals.

BACKGROUND: Hazardous alcohol use and alcohol use disorder (AUD) are highly prevalent among clients in mental health services, yet significant gaps remain in the adequate assessment of alcohol use and provision of appropriate alcohol interventions. The aim of this study was to conduct an exploration of (i) alcohol intervention elements used in mental health services and (ii) professionals' reported barriers and facilitators in identifying and intervening with hazardous alcohol use and AUD. METHODS: Qualitative data were obtained by conducting semi-structured interviews among a purposive sample of 18 professionals from 13 different Dutch mental health services organizations (i.e., five integrated mental health organizations with addiction services, five mental health organizations without addiction services, and three addiction services organizations without mental health services). Transcripts were qualitatively analyzed using inductive thematic analysis. RESULTS: Identified alcohol intervention elements included conducting assessments, brief interventions, treatment, referrals of clients, collaborations with other parties, and providing information to professionals. Professionals mentioned nine barriers and facilitators in the identification and intervention with hazardous alcohol use and AUD, including three aspects of professionals' behavior (i.e., professionals' agenda setting, knowledge and skills, and attitudes), actions related to identification and intervening, client contact, collaboration with other parties, and three factors in a wider context (i.e., organizational characteristics, organizational resources, and governmental aspects). CONCLUSIONS: Although diverse alcohol intervention elements are available in Dutch mental health services, it remains unclear to what extent these are routinely implemented. To better address hazardous alcohol use and AUD in mental health services, efforts should focus on enhancing alcohol training, improving collaboration with addiction services, providing appropriate tools, and facilitating support through organizational and governmental measures.

An empirically based typology of temporary alcohol abstinence challenge participants using latent class analysis.

INTRODUCTION: Identifying subgroups of Temporary (alcohol) Abstinence Challenge (TAC) participants may offer opportunities to enhance intervention effectiveness. However, knowledge about such subgroups is missing. This study aimed to (i) describe a TAC population; (ii) identify subgroups of participants based on determinants of changes in drinking behaviour; and (iii) characterise subgroups in terms of sociodemographic and other characteristics. METHODS: Data from 3803 Dutch TAC participants were analysed to identify subgroups using three-step Latent Class Analysis. Classes were based on determinants of changes in drinking behaviour (i.e., drinking refusal self-efficacy, craving and behavioural automaticity) and were characterised by sociodemographic characteristics, drinking behaviour, previous participation in TACs, self-reported health and life satisfaction. RESULTS: The majority of TAC participants were female, highly educated, employed, 53 years old on average, participated in previous TACs and reported relatively high alcohol use. Four classes of participants were identified: (i) 'ordinary drinkers' (49.0%); (ii) 'drinkers in control' (21.4%); (iii) 'habitual drinkers with perceived control to refuse' (18.4%); and (iv) 'drinkers not in control' (11.2%). Class 2 drank least often and non-excessive volumes, while other classes typically drank 4 or more days per week and 3 to 4 glasses per drinking day, with the highest alcohol use found in class 4. DISCUSSION AND CONCLUSIONS: Different configurations of determinants in this study's four subgroups may require different intervention approaches and might inform personalised support. Future research is needed to examine the predictive value of these subgroups on post-challenge drinking behaviour to assess support needs and participation value.

Associations between environmental characteristics and active commuting to school among children: a cross-sectional study.

BACKGROUND: Active commuting to school can contribute to active living among children, and environmental characteristics might be related to transportation mode to school. PURPOSE: The purpose of this study is to explore the association between physical and social environmental characteristics in the home, neighborhood, and school environment and walking and bicycling to school. METHOD: Data were collected among parents (n = 5,963) of children of primary schools in four Dutch cities. Parents reported mode of transportation to school, and individual, home environmental, neighborhood, and school environmental characteristics. Social as well as physical characteristics were included for the home and neighborhood environment. Multilevel multinomial logistic regression analyses were conducted to quantify the association between environmental characteristics and walking and bicycling to school. RESULTS: Three quarter of all children usually commute to school by active transportation, but age and distance from home to school were important prerequisites. Besides home environmental characteristics, lower neighborhood socioeconomic status was negatively associated with walking [odds ratio (OR) = 0.51] and bicycling (OR = 0.86). Perceived social safety was positively related to walking and bicycling (OR = 1.04 for both), as was perceived social cohesion (OR = 1.04 and 1.02 for walking and bicycling). Living in the city center was positively associated with walking (OR = 1.91), whereas living in a city green neighborhood was negatively associated with walking and bicycling (OR = 0.48 and 0.76, respectively). Traffic safety as perceived by school boards was positively associated with bicycling (OR = 1.25). CONCLUSION: This study shows that there is a relation between several characteristics in the home, neighborhood, and school environment and walking and bicycling to school among Dutch primary school children. Especially the social neighborhood characteristics were related to active commuting. Therefore, apart from providing a physical infrastructure that facilitates safe and convenient active commuting to school, policy makers should be aware of opportunities to facilitate active commuting by social initiatives in local communities.

When opinions differ: the development of a reflection tool for youth professionals to support shared decision-making with parents.

The importance of shared decision-making (SDM) in youth care is increasingly emphasised. Professional reflection on the decision-making process is an important means to improve the use of SDM in practice. In this study, we report on the development of a reflection tool for youth professionals primarily to use when they hold a different opinion then parents about referral to specialised youth care services. In co-creation with local youth professionals and parent representatives from the South of the Netherlands, the tool was developed and tested in practice. This process was guided by a three-stage cyclical research project. First, reflective group discussions provided an initial understanding of professionals' needs, interests and experiences. This input then was analysed and documented into a draft tool with reflective questions. Next, this tool was tested on fictive and real life cases and adjusted with input from youth professionals and parents. This process resulted in an online reflection tool covering 16 overarching reflective questions to support youth professionals' reflection on their shared decision-making in practice. The tool can be used and adapted by others in the field of youth care to improve the process of making shared decisions with parents in complex cases.

Actors' awareness of network governance in Child Welfare and Healthcare service networks.

To ensure that families with social and behavioral health problems get the support they need, organizations collaborate in child service networks. These networks are generally lead-organization governed. It is assumed that network members have relatively accurate information about the governance mode. However, discrepancies between the formally administered and perceived governance mode could raise legitimacy questions and lead to conflicts, and ultimately affect network effectiveness. Therefore, we investigated to what extent such discrepancies exist and how they might be explained. Hereby, the focus was on the concepts level of trust, interaction, and strength of relationship with the lead organization in the network. A comparative case study was conducted of three inter-organizational networks of child services in different-sized municipalities in the Netherlands in 2018 and 2019. A multiple generalized linear mixed model analysis was used. We found that only a minority of the network members had an accurate perception of the governance mode. This awareness did improve over time. The level of interaction and relationship strength with the lead organization were independently associated with an accurate perception of the governance mode. Trust of a network member in the network, however, had no significant association. These insights underline the necessity to consider network information accuracy as an important variable for understanding network behavior and as crucial for the effective delivery of child services.
