To test effectiveness of a parenting intervention, delivered in a community-based voluntary-sector organisation, for reducing conduct problems in clinically-referred children.
                Randomised controlled trial, follow-up at 6, 18 months, assessors blind to treatment status. Participants--76 children referred for conduct problems, aged 2-9, primarily low-income families, randomised to treatment vs. 6-month wait-list group. Retention was 93% at 6 months, 90% at 18 months. Interventions--Webster-Stratton Incredible Years video-based 14-week group programme, teaches cognitive-behavioural principles for managing behaviour, using a collaborative, practical, problem-solving approach. Primary outcomes--child problem behaviour by parent-report (Eyberg) and home-based direct observation; secondary outcomes--observed positive and negative parenting; parent-reported parenting skill, confidence and depression.
                Post-treatment improvements were found in child problem behaviour, by parent-report (effect size (ES) .48, p = .05) and direct observation (ES .78, p = .02); child independent play (ES .77, p = .003); observed negative (ES .74, p = .003) and positive (ES .38, p = .04) parenting; parent-reported confidence (ES .40, p = .03) and skill (ES .65, p =.01), using ANCOVA to control for baseline scores. Maternal depression did not change. Consumer satisfaction was high. At 18-month follow-up, although no randomised comparison was possible, changes appeared to maintain, with no significant change toward baseline level on any measure. Change in observed positive parenting appeared to mediate change in child problem behaviour (p < .025).
                Findings suggest that a group-based cognitive-behavioural parenting programme, delivered by well-trained and supervised staff, can be effective in a community voluntary-sector setting, for reducing conduct problems and enhancing parenting skills. Change in parenting skill appears to be a key mechanism for change in child behaviour. Findings have implications for feasibility of translating evidence-based programmes, even for clinically-referred conduct problems, into less specialised community settings, likely to have lower costs and be more accessible for families. Few attempts have been made to conduct randomised control trials (RCTs) of interventions for pre-school children with autism. We report findings of a pilot RCT for a parent training intervention with a focus on the development of joint attention skills and joint action routines. Twenty-four children meeting ICD-10 criteria for childhood autism (mean age = 23 months) were identified using the CHAT screen and randomised to the parent training group or to local services only. A follow-up was conducted 12 months later (mean age = 35 months). There was some evidence that the parent training group made more progress in language development than the local services group. However, the present pilot study was compromised by several factors: a reliance on parental report to measure language, non-matching of the groups on initial IQ, and a lack of systematic checking regarding the implementation of the parent training intervention. Furthermore, three parents in the local services group commenced intensive, home-based behavioural intervention during the course of the study. The difficulties encountered in the conduct of RCTs for pre-school children with autism are discussed. Methodological challenges and strategies for future well-designed RCTs for autism interventions are highlighted. Mothers of children randomly allocated to an experimental group attended fortnightly group parental language training sessions, over a 6-month period. Mothers of children allocated to a matched no intervention control group received no special attention. The results showed significantly greater gains in the expressive language skills of the experimental group compared to the control group. A second experiment was designed to compare the parental involvement approach with direct, individual treatment and to clarify the role of non-specific 'Hawthorne-type' effects. The experimental group mothers attended parental language training sessions, as above. The parental control group mothers also attended training sessions, with the emphasis on general learning skills rather than language. A third group of children received individual, direct speech and language therapy. Results showed significantly greater language gains in the parental language training group and in the individual group in comparison with the non-specific training group. The two former groups did not differ significantly, indicating that, for these groups and this methodology, parental language training is as effective as individual speech and language therapy. The results also indicate that the effectiveness of the parental involvement approach cannot be accounted for by non-specific factors. The research findings are discussed, together with the professional implications of the study and recommendations for further research. The objective of this study was to evaluate the efficacy of a home-based intervention targeted to parents with intellectual disability to promote child health and home safety in the preschool years. A total of 63 parents were recruited for the study with 45 parents (40 mothers and 5 fathers) from 40 families completing the project. The research design permitted comparison between the intervention and three alternative conditions with all parents receiving the intervention in an alternating sequence over the life of the project. The intervention consisted of 10 weekly lessons carried out in the parent's home focusing on child health and home safety. The program was adapted to suit the Australian context from the UCLA Parent--Child Health and Wellness Project (Tymchuk, Groen, & Dolyniuk, 2000). Outcome measures assessed parental health and safety behaviours. Standard measures included parental health, intelligence and literacy. The intervention improved parents' ability to recognize home dangers, to identify precautions to deal with these dangers and resulted in a significant increase in the number of safety precautions parents implemented in their homes with all gains being maintained at 3 months post-intervention. Parents' health behaviours including improved understanding of health and symptoms of illness, knowledge of and skills needed to manage life-threatening emergencies, knowledge about visiting the doctor, knowing when to call, what information to provide and what questions to ask, and how to use medicines safely significantly increased. Again, all gains were maintained 3 months post-intervention. The intervention was effective regardless of parental health, literacy skills, and IQ. This form of home-based intervention promotes a healthy and safe environment which is a prerequisite to continuing parental custody. The effectiveness of a parent training program for promoting positive parent-child relationships was examined among families of 2-year-olds. Forty-six mothers and fathers and their toddlers were assigned to either an intervention or comparison group. Intervention group parents participated in a 10-week program that focused on principles for effectively interacting with their toddlers. Parents completed measures of parenting self-efficacy, depression, stress, and perceptions of their toddler's behaviors and were videotaped playing with their toddlers preintervention, postintervention, and 3 months following the intervention. Repeated measures ANOVAs showed that the parent training program led to significant increases in maternal self-efficacy, decreases in maternal stress, and improvements in the quality of mother-toddler interactions. No significant effects were found among fathers. Explanations for obtaining different outcomes for mothers and fathers are discussed and directions for future research are recommended. To report acceptability, feasibility, and outcome data from a randomized clinical trial (RCT) of a brief intervention for caregivers of children newly diagnosed with cancer.
                Eighty-one families were randomly assigned following collection of baseline data to Intervention or Treatment as Usual (TAU). Recruitment and retention rates and progression through the protocol were tracked. Measures of state anxiety and posttraumatic stress symptoms served as outcomes.
                Difficulties enrolling participants included a high percentage of newly diagnosed families failing to meet inclusion criteria (40%) and an unexpectedly low participation rate (23%). However, movement through the protocol was generally completed in a timely manner and those completing the intervention provided positive feedback. Outcome data showed no significant differences between the arms of the RCT.
                There are many challenges inherent in conducting a RCT shortly after cancer diagnosis. Consideration of alternative research designs and optimal timing for interventions are essential next steps. Malnutrition is common among children aged 6-24 months in developing countries. It increases the risk of mortality. Interventions to improve infant-feeding hold the promise of reducing malnutrition among these children. A study in Brazil has shown the success of training in communication and counselling skills among health workers in improving the nutritional status of young children. Questions were raised whether the method used in the study in Brazil would also be effective when applied in other countries. The aim of the present study was to reduce growth faltering in young children through proper nutrition-promotion techniques. The objective of the study was to determine the efficacy of training health workers in nutrition counselling in enhancing their communication skills and performance, improving feeding practices, and reducing growth faltering in children aged 6-24 months. A cluster-randomized controlled trial was carried out. The method used in this study was a replica of the method in a similar study in Pelotas, Brazil. Forty health centres were paired, and one centre of each pair was randomly allocated to the intervention group, and the other to the control group. The Integrated Management of Childhood Illness (IMCI) module-'Counsel the mother'-was used for training health workers in the health centres in the intervention group. Data from 36 paired health centres and 375 mothers and their children aged 6-24 months recruited from these health centres following consultation with health workers were included in analysis. Independent observers, masked to the intervention status, examined the performance of health workers within the first month after training. Mother-child pairs were visited at home within two weeks, 45 days, and 180 days after recruitment. Information was recorded on the feeding practices, recall of the recommendations of health workers, and sociodemographic variables at these home-visits. Weight and length of the child were measured at each contact. The communication skills and consultation performance of health workers were significantly better in the intervention group than in the control group. The mothers' recall of the recommendation of health workers and reported infant-feeding practices were also significantly better in the intervention group than in the control group, even 180 days after the recruitment consultation. Growth faltering was less in the intervention group, with the largest effect observed among children in the age-group of 12 + months. These results indicate that training in IMCI feeding counselling can enhance the communication skills and performance of health workers. Improved feeding practices of counselled mothers can, in turn, reduce growth faltering in their children. Despite recognition of the need for parenting interventions to prevent childhood behavioral problems, few community programs have been evaluated. This report describes the randomized controlled evaluation of a four-session psychoeducational group for parents of preschoolers with behavior problems, delivered in community agencies.
                In 1998, 222 primary caregivers, recruited through community ads, filled out questionnaires on parenting practices and child behavior. Parents were randomly assigned to immediate intervention or a wait-list control. The intervention comprised three weekly group sessions and a 1-month booster, the focus being to support effective discipline (using the video 1-2-3 Magic) and to reduce parent-child conflict.
                Using an intent-to-treat analysis, repeated-measures analyses of variance indicated that the parents who received the intervention reported significantly greater improvement in parenting practices and a significantly greater reduction in child problem behavior than the control group. The gains in positive parenting behaviors were maintained at 1-year follow-up in a subset of the experimental group.
                This brief intervention program may be a useful first intervention for parents of young children with behavior problems, as it seems both acceptable and reasonably effective. The goal was to assess the risk of bias among pediatric, randomized, controlled trials (RCTs) reported in 8 high-impact journals.
                We searched PubMed for all pediatric RCTs reported between July 1, 2007, and June 30, 2008, in 8 journals with high impact factors. Using Cochrane Collaboration methods for risk assessment, we evaluated all reports for risk of bias according to domain (ie, randomized sequence generation, allocation concealment, masking, incomplete outcome data, selective outcome reporting, and other). We used multiple logistic regression to test for associations between the presence of a high risk of bias according to domain and funding source, intervention type, trial registration, and multicenter status.
                Industry-funded RCTs were more likely to show a high risk of bias for sequence generation, compared with government-funded RCTs (adjusted odds ratio [aOR]: 6.1 [95% confidence interval [CI]: 1.70- 21.89]), and behavioral/educational trials were more likely to show a high risk of bias for sequence generation (aOR: 2.8 [95% CI: 1.06-7.36]) and allocation concealment (aOR: 4.09 [95% CI: 1.69-9.90]), compared with drug trials. Registered trials were less likely to have a high risk of bias for sequence generation, compared with nonregistered trials (aOR: 0.33 [95% CI: 0.15-0.71]).
                Overall, we found a large proportion of pediatric RCT reports with a high risk of bias for sequence generation and allocation concealment. Factors associated with a high risk of bias included industry funding and assessment of behavioral/educational interventions, whereas trial registration was associated with a lower risk of bias.
There is some risk of bias in the included studies, with limited information available to assess possible bias and to fully assess the findings of one included study. Whilst the evidence presented here does seem promising with regard to the ability of such interventions to improve parenting knowledge and skill in this population, there is a need for larger RCTs of interventions before conclusions can be drawn about the effectiveness of parent training for this group of parents.
