BACKGROUND/AIMS
Adverse early life experiences are associated with the development of stroke, cancer, diabetes, and chronic respiratory and ischemic heart diseases. These negative experiences may also play a role in the development of irritable bowel syndrome (IBS)--a functional gastrointestinal disease. This review discusses the research to date on the parental, perinatal, and childhood risk and protective factors associated with the development of IBS.
METHODS
A literature search was completed for studies published between 1966 and 2018 that investigated premorbid factors occurring during the perinatal and childhood periods as well as parental factors that were associated with the development of IBS.
RESULTS
Twenty-seven studies fulfilled the review criteria. Risk factors that appeared in more than one study included: (1) parental IBS, substance abuse, parental punishment, and rejection as parental risk factors; (2) low birth weight as a perinatal risk factor; and (3) crowded living conditions in low-income families, childhood anxiety, depression, or child abuse as childhood risk factors. Protective factors for IBS were emotional warmth from the parents and being born to an older mother.
CONCLUSIONS
More effort is needed to identify what fetal and maternal factors are associated with low birth weight and IBS. A well-executed prospective birth cohort with a collection of bio-samples and functional data will provide a better understanding of how adversity and the interplay between genetics, epigenetics, and numerous risk factors affect the development of IBS.

Review
BACKGROUND
The negative impact of unnecessary diagnostic tests on healthcare systems and patients has been widely recognized. Medical researchers in various countries have been devoting effort to reduce unnecessary diagnostic tests by using different types of interventions, including information and communications technology-based (ICT-based) intervention, educational intervention, audit and feedback, the introduction of guidelines or protocols, and the reward and punishment of staff. We conducted a review of ICT based interventions and a comparative analysis of their relative effectiveness in reducing unnecessary tests.
METHOD
A systematic Boolean search in PubMed, EMBase and EBSCOhost research databases was performed. Keyword search and citation analysis were also conducted. Empirical studies reporting ICT based interventions, and their implications on relative effectiveness in reducing unnecessary diagnostic tests (pathology tests or medical imaging) were evaluated independently by two reviewers based on a rigorously developed coding protocol.
RESULTS
92 research articles from peer-reviewed journals were identified as eligible. 47 studies involved a single-method intervention and 45 involved multi-method interventions. Regardless of the number of interventions involved in the studies, ICT-based interventions were utilized by 71 studies and 59 of them were shown to be effective in reducing unnecessary testing. A clinical decision support (CDS) tool appeared to be the most adopted ICT approach, with 46 out of 71 studies using CDS tools. The CDS tool showed effectiveness in reducing test volume in 38 studies and reducing cost in 24 studies.
CONCLUSIONS
This review investigated five frequently utilized intervention methods, ICT-based, education, introduction of guidelines or protocols, audit and feedback, and reward and punishment. It provides in-depth analysis of the efficacy of different types of interventions and sheds insights about the benefits of ICT based interventions, especially those utilising CDS tools, to reduce unnecessary diagnostic testing. The replicability of the studies is limited due to the heterogeneity of the studies in terms of context, study design, and targeted types of tests.

Review
Decreased social functioning and high levels of loneliness and social isolation are common in schizophrenia spectrum disorders (SSD), contributing to reduced quality of life. One key contributor to social impairment is low social motivation, which may stem from aberrant neural processing of socially rewarding or punishing stimuli. To summarize research on the neurobiology of social motivation in SSD, we performed a systematic literature review of neuroimaging studies involving the presentation of social stimuli intended to elicit feelings of reward and/or punishment. Across 11 studies meeting criteria, people with SSD demonstrated weaker modulation of brain activity in regions within a proposed social interaction network, including prefrontal, cingulate, and striatal regions, as well as the amygdala and insula. Firm conclusions regarding neural differences in SSD in these regions, as well as connections within networks, are limited due to conceptual and methodological inconsistencies across the available studies. We conclude by making recommendations for the study of social reward and punishment processing in SSD in future research.

Meta-Analysis Review
Just as happy people see the proverbial glass as half-full, 'optimistic' or 'pessimistic' responses to ambiguity might also reflect affective states in animals. Judgement bias tests, designed to measure these responses, are an increasingly popular way of assessing animal affect and there is now a substantial, but heterogeneous, literature on their use across different species, affect manipulations, and study designs. By conducting a systematic review and meta-analysis of 459 effect sizes from 71 studies of non-pharmacological affect manipulations on 22 non-human species, we show that animals in relatively better conditions, assumed to generate more positive affect, show more 'optimistic' judgements of ambiguity than those in relatively worse conditions. Overall effects are small when considering responses to all cues, but become more pronounced when non-ambiguous training cues are excluded from analyses or when focusing only on the most divergent responses between treatment groups. Task type (go/no-go; go/go active choice), training cue reinforcement (reward-punishment; reward-null; reward-reward) and sex of animals emerge as potential moderators of effect sizes in judgement bias tests.

Pica is the persistent consumption of non-nutritive, nonfood substances and is associated with adverse health complications. However, there is limited research on interventions for pica in youth. The objective of this study is to systematically review the empirical evidence for the effectiveness of behavioural interventions for pica in children and adolescents and to generate treatment recommendations. A systematic search yielded 823 articles extracted from five databases: CINALH, Family and Society Studies Worldwide, Medline, PsycINFO, and Web of Science. Two reviewers completed initial sorting based on article titles and abstracts. Five reviewers completed sorting based on full article review. Thirty articles were included and double coded for demographic information, co-morbid conditions, and intervention characteristics. These studies were case studies involving behavioural treatments for pica. Seventeen behavioural interventions were categorized into four treatment approaches: reinforcement-based, response interruption, "other" interventions, and punishment-based procedures. Interventions that resulted in near-zero rates of pica were deemed effective. Findings showed support for contingent reinforcement, discrimination training as part of a combination treatment, physical restraint, time out, and contingent aversive stimulus. No evidence supported the effectiveness of response interruption procedures, including response blocking and visual facial screen. Other coded procedures did not appear effective. We recommend that the least restrictive procedures are implemented first, including a combination treatment with contingent reinforcement and discrimination training. As needed, more restrictive procedures can be added to the treatment package. This review will facilitate future empirical work and assist clinicians with treatment options for pica in youth. High-quality trials are needed.

Models of anorexia nervosa (AN) posit that symptoms are maintained through deficient reward and enhanced punishment processing. However, theoretical and empirical inconsistencies highlight the need for a more nuanced conceptualization of this literature. Our goal was to comprehensively review the research on reward and punishment responding in AN from a cue-specific lens to determine which stimuli evoke or discourage reward and punishment responses in this population, and, ultimately, what properties these rewarding and punishing cues might share. A systematic review interrogating reward and punishment responses to specific cues yielded articles (n = 92) that examined responses to disorder relevant (e.g., food) and irrelevant (e.g., money) stimuli across self-report, behavioral, and biological indices. Overall, in most studies individuals with AN exhibited aversive responses to cues signaling higher body weights, social contexts, and monetary losses, and appetitive responses to cues for weight loss behaviors and thinness. Findings were more mixed on responses to palatable food and monetary gains. Results highlight that reward and punishment responding in AN are context specific and may be affected by varied stimulus qualities (e.g., predictability, controllability, delay, effort). Increasing specificity in future research on reward and punishment mechanisms in AN will better inform development of precisely-targeted interventions.

Despite global shifts toward prevention of school corporal punishment, the practice remains widespread. This systematic review focused on (a) prevalence, (b) associated mental health and behavioral factors, and (c) correlates that may be risk or protective factors. Studies included in this review were peer-reviewed, published in English between 1980 and July 2017, and quantitative in design. Fifty-three papers met the inclusion criteria. All were cross-sectional surveys, predominantly of moderate quality and conducted in the United States (US) and on the African continent. Results indicated that school corporal punishment is prevalent across the globe (including where bans are in place) and does not appear to be decreasing over time, although measurement differences preclude firm conclusions. It is associated with physical, academic, mental health, and behavioral problems for children. Boys, Black students (in the US), and students exposed to violence at home were most at risk of corporal punishment. It is unclear whether disability puts a student at risk. Schools with high rates of other disciplinary practices were more likely to use corporal punishment, while those who employed a mental health professional and trained staff in safety procedures were less likely to use corporal punishment. Teacher attitudes favoring corporal punishment, and their use of violence in other contexts, increased risk. Low socioeconomic status (of the student or the school environment) increased risk, while high levels of state social capital reduced risk. Future research must include areas where corporal punishment is banned and focus on developing effective interventions to prevent school corporal punishment.

OBJECTIVE
Serious health games might have the potential to prevent tobacco smoking and its health consequences, depending on the inclusion of specific game elements. This review aimed to assess the composition of serious games and their effects on smoking initiation prevention and cessation and behavioral determinants.
MATERIALS AND METHODS
We systematically searched MEDLINE, Embase, PsycINFO, and Web of Science for publications that evaluated serious games aimed at changing smoking behavior or behavioral determinants. A taxonomy by King et al was used to classify game elements.
RESULTS
We identified 15 studies, evaluating 14 unique serious games. All games combined multiple game elements (mean 5.5; range, 3-10). Most frequently used were general and intermittent rewards, theme and genre features, and punishments. Six studies on smoking prevention together assessed 20 determinants and found statistically significant positive effects for 8 determinants (eg, attitude, knowledge, intention). Of 7 studies on smoking cessation, 5 found positive, statistically significant effects on smoking cessation or status. These studies found statistically significant positive effects for 6 of 12 determinants (eg, self-efficacy, attitude, intention). The majority of included studies had poor or fair methodological quality, lacked follow-up measures, and had fixed (as opposed to free, on-demand) play sessions.
CONCLUSIONS
Serious games included multiple types of game elements. The evidence from a number of studies suggests that games may have positive effects on smoking-related outcomes, particularly smoking cessation. However, as most studies had important methodological limitations, stronger designs are needed to demonstrate, quantify, and understand the effects of serious games.

Comparative Study
In order to improve the demand-supply-mismatch in transplantation medicine, policy makers have to think about adapting existing legal frameworks for donor organ allocation. This study aims to systematically review preferences of physicians as well as patients in the field of transplantation medicine. PubMed, Web of Science, EBSCO and PsycINFO were searched from January 2000 to December 2018 without language restrictions. Fourteen publications were identified, six aiming at physicians, seven focusing on patients and one on both groups. The criteria used in these studies to elicit preferences can be grouped into six different main categories, all deriving from the general principle of equality: "Effectiveness/Benefit", "Medical urgency", "Own fault", "Social value", "Medical background" and "Socio-demographic status". Whilst patients on the one hand show a high demand for equal access, outcome maximization and punishment for damaging behaviors, they would still allocate organs to people with very low survival chances. Physicians decide against equal access to transplantation in cases where clinical evidence is weighed more heavily, e.g. in the cases of ethnicity and sex. Also, they seem more informed regarding the involvement of medical factors and give less importance to those with uncertain effects on transplantation outcome, such as tissue or blood group match. It is important to continuously monitor preferences of all involved stakeholders in order to achieve fair and accessible transplantation systems.

OBJECTIVE
We aimed to systematically review recidivism rates in individuals given community sentences internationally. We sought to explore sources of variation between these rates and how reporting practices may limit their comparability across jurisdictions. Finally, we aimed to adapt previously published guidelines on recidivism reporting to include community sentenced populations.
METHODS
We searched MEDLINE, PsycINFO, SAGE and Google Scholar for reports and studies of recidivism rates using non-specific and targeted searches for the 20 countries with the largest prison populations worldwide. We identified 28 studies with data from 19 countries. Of the 20 countries with the largest prison populations, only 2 reported recidivism rates for individuals given community sentences.
RESULTS
The most commonly reported recidivism information between countries was for 2-year reconviction, which ranged widely from 14% to 43% in men, and 9% to 35% in women. Explanations for recidivism rate variations between countries include when the follow-up period started and whether technical violations were taken into account.
CONCLUSION
Recidivism rates in individuals receiving community sentences are typically lower in comparison to those reported in released prisoners, although these two populations differ in terms of their baseline characteristics. Direct comparisons of the recidivism rates in community sentenced cohorts across jurisdictions are currently not possible, but simple changes to existing reporting practices can facilitate these. We propose recommendations to improve reporting practices.
