We assessed risk groups for excessive infant crying using 10 published definitions, in 3179 children aged 1-6 months (response: 96.5%). Risk groups regarding parental employment, living area, lifestyle, and obstetric history varied by definition. This may explain the existence of conflicting evidence on the occurrence and cause of excessive crying.

Child abuse and neglect are important causes of child morbidity and death. We assessed potentially detrimental parental actions induced by infant crying in 3259 infants aged 1-6 months, in the Netherlands. In infants aged 6 months, 5·6% (95% CI 4·2-7·0) of parents reported having smothered, slapped, or shaken their baby at least once because of its crying. The risks of detrimental actions were highest for parents from non-industrialised countries, those with either no job or a job with short working hours, and those who judged their infant's crying to be excessive. Clinicians should be aware of the risks of abuse in children known to cry a lot and should target interventions at parents to help them cope with this crying.

Objective. To estimate the prevalence of parental actions to stop infant crying that may threaten infant health, and to determine specific risk groups regarding these actions. Design. Descriptive. Method. Before their visit to a well-baby clinic in the Netherlands, parents of 3345 infants aged 1-6 months (96.5% response) filled out an anonymous questionnaire on actions that they undertook to stop their child crying. Results. At 6 months, 5.6% (95% confidence interval: 4.2-7.0%) of all the parents reported having smothered, slapped, or shaken their infant at least once because of its crying. The highest risks for detrimental parental actions were run by infants of parents from non-industrialised countries, of parents with no or only a part-time job, and of parents who had judged their infant's crying as excessive. Conclusion. Clinicians should be aware of the observed risk factors for abuse of young children known to cry a lot, in order to help parents to cope with this crying.

Objective: To investigate whether false-positive outcomes on neonatal hearing screening cause long-lasting parental concerns. Methods: A general population of parents whose children had participated in the universal neonatal hearing screening (UNHS) programme were examined. Parents filled out a questionnaire 6 months after UNHS. Outcomes were compared for all parents whose child tested positive or inconclusive in at least one of three tests but afterwards proved not to have hearing impairment (cases, n = 154| and a random sample of parents whose child passed the first test (controls, n = 288). Parental anxiety as measured with the State-Trait Anxiety Inventory (STAI), attitude towards the child (child health rating and experienced problems) and sensitivity to hearing problems were measured. Results: Median STAI score was equal for cases and controls. Parental attitudes toward the child also did not differ. The difference in the proportion of parents who worried about their child's hearing was statistically significant between cases and controls (p = 0.001) and varied with the number of screens; 4% of controls were worried about the child's hearing, as compared to 10% of cases whose children were tested twice, and 15% of cases whose children were tested three times. Conclusions: False-positive UNHS test results do not cause long-term general parental anxiety. However, 6 months after screening, a considerable proportion of parents continued to experience hearing-specific worries regarding their child.

Health-related quality of life (HRQoL), conceptualized as patients' own evaluations of their health status, is an important criterion in evaluating health and health care and in the treatment of individual patients. Until now, few systematic attempts have been made to develop instruments to assess the HRQoL of children using such a conceptualization. This article describes the conceptualization and results of a study aiming to develop such an instrument for children aged 6-15 years using their parents as a proxy. The feasibility and psychometric performance of the instrument were evaluated in a study of 77 patients of the paediatric out-patient clinic of Leiden University Hospital. For each of the a priori-defined domains, a parent form scale could be constructed with satisfactory reliability and moderate correlations with the other scales. Only some of the parents indicating health status problems also signalled negative reactions to these problems. This is, in our view, a strong argument for the distinction between health status and quality of life (QoL). The correlation coefficients between the parent form and a children's questionnaire were low. Overall, the psychometric performance of the TACQOL parent form looks promising, which suggests that this instrument - with some modifications - can indeed be used to assess group differences in HRQoL in children. The results, however, should be replicated in larger samples, currently under study. The relation between parents' proxy reports on the HRQoL of their children and children's self-reports needs further investigation.

Background. The objective of this study was to determine the importance of parental factors possibly related to dietary control in early and continuously treated patients with phenylketonuria (PKU). Methods. A questionnaire was disseminated among parents of 238 patients with PKU born after the nationwide introduction of newborn screening for PKU (1 September 1974) until 31 December 1995. The questionnaire was based on a behavioural model measuring people's attitudes, subjective norms, and self-efficacy. Dietary control was defined on the basis of mean phenyl-alanine (Phe) concentration of the PKU patients measured between 1 January 1994 and 31 December 1996. Results. Response rate was 71%. Attitudes: children of parents who believed that their child adheres well to the diet, even if his or her Phe concentrations are sometimes too high, had lower Phe concentrations than children of parents who disagree with this statement (adjusted difference -103 μmol/L, p < 0.001). Subjective norm: Phe concentrations were higher when parents answered that their relatives did not approve when their child deviates from the diet (p = 0.004). Self-efficacy: children of parents who reported difficulties in having their child eat the synthetic protein substitute three times a day had higher Phe concentrations than those of parents who did not have such difficulties (adjusted difference 156 μmol/L, p = 0.007). Conclusion. More attention should be given to parents having their child eat the synthetic protein substitute at least three times a day and to teaching parents to keep strictly to the diet without being too rigid. These factors were strongly associated to dietary control and may be amenable to change. © SSIEM and Springer 2005.

The aim of the present study is to assess the attitudes of parents toward vaccination as well as their risk perception of disease and vaccination. We interviewed 1763 parents of different ethnic groups (among others, Dutch, Turkish, Moroccan, and Surinamese parents). Results show that there were large differences in knowledge about disease and risk perception of disease and vaccination among parents of different ethnic backgrounds. Generally, people largely overestimated the risk of contracting the disease and the risk of dying after contracting the disease. Dutch parents were best informed, least worried, had the most critical attitude toward the campaign, and the lowest vaccination level compared to other parents. The differences in knowledge about vaccination and the more critical attitude of Dutch parents emphasize the need to take more into account parents' perspectives when designing information leaflets or other information media. © 2005 Elsevier Ltd.

Background. We examined the association of area deprivation with the occurrence of psychosocial problems among children aged 4-16 in a representative national sample of children based on standardised measures of parent-reported problems and diagnoses made by doctors and nurses working in child healthcare (child health professionals, CHPs). Methods. The study comprised 4480 children aged 4-16 years, eligible for a routine health assessment (response: 90.1 %), in 19 Child Healthcare Services across the Netherlands that routinely provided preventive child healthcare to nearly all school-aged children. Parents completed the Child Behaviour Checklist (CBCL). CHPs examined the child and interviewed parents and child during their routine health assessments. Main outcome measures concerned psychosocial problems as reported by parents (i. e. a clinical score on the CBCL) and as identified by CHPs. Results. Prevalence rates of psychosocial problems were 8.6% for parent-reported problems and 10.1 % for CHP-identified problems. They were much higher in the most deprived third of the areas. Odds ratios (95 % confidence intervals) compared with the least deprived third were 1.93 (1.41-2.64) regarding parent-reported problems and 1.76 (1.30-2.38) regarding CHP-identified problems. Regarding parent reports, associations were slightly stronger for behavioural problems than for emotional problems. Less than a quarter of the area differences could be explained by individual and family characteristics. Conclusions. Child psychosocial problems occur more frequently in deprived areas. Both preventive and curative health services should be better equipped for this concentration of child and adolescent morbidity in deprived areas. © Steinkopff Verlag 2005.

Background: In the Netherlands, preventive child health service (CHS) screening plays an important role in the early detection of congenital, developmental, physical, and mental disorders. Objective: To obtain insight into the referral patterns of children from CHS to general practitioners and from general practitioners to medical specialists. Methods: Prospective study over 6 months in a semi-urban area in the Netherlands. All correspondence from the participating doctors was sticker marked and, after each contact, a registration card was sent to a central secretariat. The referral stream between general practitioners and specialists or allied health professionals was extracted from a central database. The general practitioners and the participating paediatricians were asked to complete a questionnaire about the quality and necessity of the referral. Results: Out of an estimated 2600 examinations, 45 children were referred to their general practitioners for further examination. The problems of eight children were settled by the GP, 10 children were referred to allied health professionals, and 24 children were referred to specialists. The median time span of showing up at the GP's office was 6.5 days. Sixteen per cent showed up long after having been referred by the CHS. The parents of three children did not comply. Of the 397 referrals from GPs to medical specialists and allied health professionals, 8.5% were initiated by the CHS. Conclusion: The amount of referrals from the CHS to GPs and of referrals from GPs to medical specialists and allied health professionals initiated by the CHS is low in terms of absolute percentages. Most referrals by the CHS were considered useful.

The aim of this case-control study was to explore the relationship between parenting practices, parent-child interaction and childhood dental caries, using a sample of 5-8-year old children from the Netherlands. Cases were defined as children with four or more decayed, missing or filled teeth and controls were caries free. Cases (n=28) and controls (n=26) were recruited from a referral centre for paediatric dental care and a general dental practice, respectively. Parenting practices and parent-child interactions of the child's primary caregiver were observed using Structured Interaction Tasks and subsequently rated on seven dimensions: positive involvement, encouragement, problem-solving, discipline, monitoring, coercion and interpersonal atmosphere. All Structured Interaction Tasks were videotaped, and coded by trained and calibrated observers blind to the dental condition. Differences in parenting dimensions between cases and controls were analysed using multivariate analysis of variance, independent samples T-tests, χ2-tests and multiple logistic regression analyses. Controls had significantly higher scores on the dimensions positive involvement, encouragement, problem-solving and interpersonal atmosphere, compared to cases. Parents of controls were also less likely to show coercive behaviours. These associations remained statistically significant after adjustment for the mother's education level, tooth brushing frequency and the frequency of consuming sugary foods and drinks, except for coercion. There was no significant difference in discipline between cases and controls. In conclusion, this case-control study found a significant relationship between parenting practices, parent-child interaction quality and childhood dental caries. Our findings suggest that parenting practices may be an important factor to consider in caries preventive programs. © 2014 Elsevier Ltd.
