Multimedia versus written information for nocturnal enuresis education: a cluster randomized controlled trial.

OBJECTIVE: This study evaluated the impact of child-focused information provision using a multimedia software package 'All About Nocturnal Enuresis' and written leaflets containing the same information for bedwetting children. DESIGN: A stratified cluster randomized controlled trial with data on 270 children collected longitudinally. SETTING: Fifteen school nurse-led community enuresis clinics in Leicestershire, UK. MAIN OUTCOME MEASURES: The outcome measures were becoming and remaining dry and time to dry, non-attendance and dropout rates. The psychological measures completed by children were the impact of bedwetting and Coopersmith self-esteem scales. Parents completed the maternal tolerance scale. RESULTS: No significant intervention effect was found for any of the outcome measures recorded during treatment, at discharge or six-months post discharge. CONCLUSIONS: Multimedia educational programs and written leaflets are widely used to enable children to learn more about their health-related conditions. However, our result suggests that multimedia is no more effective than traditional materials at effecting health-related behavioural change.

An investigation of the impact of nocturnal enuresis on children's self-concept.

OBJECTIVE: This study sought to evaluate the relationship between the self-esteem and the self-image of children with nocturnal enuresis and to examine these in relation to various aspects of clinical and demographic variables. Previous studies investigating the self-esteem of bedwetting children have had mixed findings. Some studies report that children with nocturnal enuresis have a lower self-esteem than their non-bedwetting peers, but other studies report that children with nocturnal enuresis perceive themselves similarly to non-bedwetting children. However, what have not been studied to date are the self-perceptions of bedwetting children treated in community clinics. MATERIAL AND METHODS: A total of 114 bedwetting children treated in community clinics provided the sample. School nurses conducted a routine first-visit assessment, collected baseline demographic and social information and invited children to complete the Butler Self-Image Profile and the Coopersmith Self-Esteem Inventory. RESULTS: Age and extent of wetting were not significantly related to self-concept measures. Girls had significantly (p = 0.008) higher scores on positive self-image compared with boys. Children with secondary enuresis also scored higher on positive self-image compared with those with primary nocturnal enuresis (p = 0.02). The Butler self-image scores indicated a number of significant links between positive self-image and enuresis variables, whereas the Coopersmith self-esteem scores generally failed to distinguish between the enuresis variables and closely reflected those of the negative self-image scores. CONCLUSIONS: These findings suggest that amongst children with nocturnal enuresis, the most vulnerable in terms of self-image are male, those with primary enuresis and those with a greater number of wet nights a week.

The Data Protection Act (1998): implications for health researchers.

AIMS: This paper reports on the methods used in two studies to obtain access to subjects to comply with the common law duty of confidence laid out in the Data Protection Act (1998) and discusses the researchers' problems in interpreting the procedures. RATIONALE: The amendments to the United Kingdom (UK) Data Protection Act (1998) are causing confusion within the health service and academic institutions. There is a need to balance patient confidentiality with the requirement to conduct vital, unbiased research in which health service professionals are not subject to ethical dilemmas. This paper examines the recruitment methods used in two studies in which the researchers' attempts to adhere to the requirements lengthened the study costs and may have produced less reliable results. METHODS: The methodological difficulties in two studies are presented. In Study 1, the difficulties encountered when the Multicentre Research Ethics Committee refused permission for researchers to recruit patients directly to a multicentre randomized controlled trial are discussed. In Study 2, the method used to compile a sampling frame for a national questionnaire survey following the eight principles of the Act are described. FINDINGS: Our experience has shown that health care professionals are increasingly required to recruit patients to intervention trials, and that researchers are not allowed access to the names of patients or other subjects to ask them for consent to participate in a study. The requirement for researchers to use "intermediaries" to obtain consent from and recruit subjects to studies increases the risk of selection bias, may expose the practitioner to ethical difficulties and may compromise the external validity of trial results. There is also a danger that research costs will soar when the Data Protection Act (1998) is fully realized. CONCLUSION: The Data Protection Act (1998) is currently being interpreted in a number of different ways. We conclude there is an urgent need for consensus within the health service and academic communities.

Bedwetting, behaviour and self-esteem: a review of the literature.

AIM: The aim of this review was to examine the empirical evidence on the impact of bedwetting and its treatment on a child's self-esteem and behaviour. INCLUSION CRITERIA: The inclusion criteria for this review were empirical studies conducted on children, aged 5-16 years old, with primary nocturnal enuresis using measures of self-esteem or behaviour. Studies utilizing psychological measurement scales completed by children were the main focus although those that used scales completed by parents were also included. SEARCH STRATEGIES: The electronic databases from 1981 to 1999 were searched, and hand searching of the literature dating back to 1973 was conducted using the reference lists of key papers. RESEARCH FINDINGS: Fifteen empirical studies matched the inclusion criteria. There was only one randomised-controlled trial and the rest of the studies were cohort, case-control or cross-sectional design. Evidence of sample bias predominantly due to the use hospital-based and/or 'volunteer' subjects was found in five studies. A further five studies used birth cohort data, which excludes important variables such as the impact of treatment. Four studies used single parent-reported measures, which may under or over-estimate the problem. No large cohort studies were available which compare the self-esteem of bedwetting children with matched controls. The most interesting line of enquiry is pursued by studies looking at whether self-esteem improves with successful treatment. However, the use of self-selected subject groups does not make the current evidence convincing and more work is required to determine outcomes for all children. There is empirical evidence for increased behavioural problems in bedwetting children. Studies conducted on younger children report less behavioural problems with more reported in studies conducted on older children with complex wetting disorders. This may point towards wetting being the primary problem, but more work is needed, as causation in any direction is difficult to ascertain from the literature.

Using multimedia for patient information--a program about nocturnal enuresis.

OBJECTIVES: To identify the information needs of children with nocturnal enuresis, and to design, produce and evaluate an interactive computer program to provide this information. SUBJECTS AND METHODS: The program was developed over an 18-month period using information provided by children, parents and professionals, and was evaluated in a hospital-based enuresis clinic in 65 children. Usability and knowledge gained were also evaluated in 43 healthy children aged 8-10 years attending a local inner-city primary school. RESULTS: An interactive program about nocturnal enuresis was developed, which runs on a personal computer and uses sound, voice, cartoon drawings and animation in a modular design. Knowledge scores increased in clinic attendees and in schoolchildren after using the program (Wilcoxon matched pairs test, P < 0.001). This improvement was maintained when the program was re-tested 6-10 months later. CONCLUSION: This interactive computer program holds children's attention and increases their understanding of enuresis. Interactive multimedia may be useful to complement the information provided by health professionals. This method of communication may be particularly useful for children with a low level of literacy.
