The current article details a position statement and recommendations for future research and practice on planning and implementation intentions in health contexts endorsed by the Synergy Expert Group. The Group comprised world-leading researchers in health and social psychology and behavioural medicine who convened to discuss priority issues in planning interventions in health contexts and develop a set of recommendations for future research and practice. The Expert Group adopted a nominal groups approach and voting system to elicit and structure priority issues in planning interventions and implementation intentions research. Fortytwo priority issues identified in initial discussions were further condensed to 18 key issues, including definitions of planning and implementation intentions and 17 priority research areas.Each issue was subjected to voting for consensus among group members and formed the basis of the position statement and recommendations. Specifically, the Expert Group endorsed statements and recommendations in the following areas: generic definition of planning and specific definition of implementation intentions, recommendations for better testing of mechanisms, guidance on testing the effects of moderators of planning interventions, recommendations on the social aspects of planning interventions, identification of the preconditions that moderate effectiveness of planning interventions, and recommendations for research on how people use plans.

The aim of this study was to assess the occurrence of post-concussion symptoms and post-concussion syndrome (PCS) in a large cohort of patients after complicated and uncomplicated mild traumatic brain injury (mTBI) at three and six months post-injury. Patients were included through the prospective cohort study: Collaborative European NeuroTrauma Effectiveness Research (CENTER-TBI). Patients enrolled with mTBI (Glasgow Coma Scale 13–15) were further differentiated into complicated and uncomplicated mTBI based on the presence or absence of computed tomography abnormalities, respectively. The Rivermead Post-Concussion Symptoms Questionnaire (RPQ) assessed post-concussion symptoms and PCS according to the mapped ICD-10 classification method. The occurrence of post-concussion symptoms and syndrome at both time points was calculated. Chi square tests were used to test for differences between and within groups. Logistic regression was performed to analyse the association between complicated versus uncomplicated mTBI and the prevalence of PCS. Patients after complicated mTBI reported slightly more post-concussion symptoms compared to those after uncomplicated mTBI. A higher percentage of patients after complicated mTBI were classified as having PCS at three (complicated: 46% vs. uncomplicated: 35%) and six months (complicated: 43% vs. uncomplicated 34%). After adjusting for baseline covariates, the effect of complicated versus uncomplicated mTBI at three months appeared minimal: odds ratio 1.25 (95% confidence interval: 0.95–1.66). Although patients after complicated mTBI report slightly more post-concussion symptoms and show higher PCS rates compared to those after uncomplicated mTBI at three and six months, complicated mTBI was only found a weak indicator for these problems.

Objective: To study psychological outcomes, knowledge, recall and understanding of test-results, satisfaction, and reproductive intentions among 97 Western and 46 non-Western participants in a unique preconceptional carrier screening study for both cystic fibrosis and hemoglobinopathies in a multiethnic population the Netherlands, in which a couple's eligibility for cystic fibrosis and/or hemoglobinopathies testing was based on both partners' ancestry. Methods: Questionnaires before and after pretest consultation, and 1 week and 3 months after receiving test-results. Three cystic fibrosis and seven hemoglobinopathy carriers were identified, but no carrier couples.Results: Overall, anxiety levels were low, knowledge improved after pretest consultation but decreased after 3 months. Ninety-four percent remembered their test-results. Western compared with non-Western participants had higher knowledge-scores and better understanding of test-results. None of the carriers felt less healthy, six felt relieved, and one felt disappointed. Four carriers were unaware of the residual risk of having an affected child.Participants intended to draw reproductive decisions from test-results, were satisfied, did not regret participation, and did not report major feelings of discrimination or stigmatization. Conclusions: Similar to previous studies, no major adverse psychological effects were demonstrated among the Western and non-Western participants in this study, and they would draw reproductive decisions on test-results. No arguments for rejecting a combined offer of preconceptional ancestry-based cystic fibrosis and hemoglobinopathies carrier screening were found. An extensive implementation study should be carried out, in which understanding of test-results needs further attention, to investigate whether or not this type of screening should be implemented on a large scale in the Netherlands.

This paper explores determinants of the intention to participate or not and of actual participation in preconceptional ancestry-based carrier couple screening for cystic fibrosis (CF) and haemoglobinopathies (HbPs). In total, 9453 individuals from a multi-ethnic population were invited. Invitees who had a partner and who were planning a pregnancy were the target population (33 -36%). Test participation was conditional on survey participation. Those who refrained from test participation were asked to participate in the survey only. The questionnaire was based on the Theory of Planned Behaviour, which explains behaviour through intention. It was completed by 418 survey participants: 171 who intended to participate in the testing, and 247 who refrained from test participation. Both test intenders and offer decliners generally had a positive attitude towards test participation, and perceived high behavioural control. This applied to Western and non-Western survey participants equally. Offer decliners, however, perceived less control in terms of the time and effort needed for participation. Still, 68% of them intended to participate in the future if the screening would be offered routinely. Test intenders more often would draw reproductive consequences from test results, perceived a higher risk of being a carrier, more benefits and less adverse psychological outcomes. Feelings of stigmatisation were not an important issue, but 14% thought that there would be discrimination against carriers: among them more were non-Western survey participants. Preconceptional ancestry-based CF and HbPs carrier screening was evaluated as positive and desirable among Western and non-Western survey participants. The effort and time needed for participation were important reasons for declining participation, which might be overcome by improving access to the screening.

Prospective parents in the Dutch population seem interested in newborn screening for untreatable childhood-onset disorders; therefore, we argue that additional debate of pros and cons is needed among policy makers, health care professionals, and consumers.
