Treatment fidelity as a predictor of behaviour change in parents attending group-based parent training.

BACKGROUND: Change in parenting skills, particularly increased positive parenting, has been identified as the key component of successful evidence-based parent training (PT), playing a causal role in subsequent child behaviour change for both prevention and treatment of Conduct Disorder. The amount of change in parenting skills observed after PT varies and may be accounted for by both the content of the programme and by the level of PT implementer process skills. Such variation in implementer skills is an important component in the assessment of treatment fidelity, itself an essential factor in successful intervention outcome. AIMS: To establish whether the Leader Observation Tool, a reliable and valid process skills fidelity measure, can predict change in parenting skills after attendance on the Incredible Years PT programme. RESULTS: Positive leader skills categories of the Leader Observation Tool significantly predicted change in both parent-reported and independently observed parenting skills behaviour, which in turn, predicted change in child behaviour outcome. CONCLUSIONS: Delivering an intervention with a high level of treatment fidelity not only preserves the behaviour change mechanisms of the intervention, but can also predict parental behaviour change, which itself predicts child behaviour change as a result of treatment.

Efficacy of the Incredible Years Programme as an early intervention for children with conduct problems and ADHD: long-term follow-up.

BACKGROUND: This study examined the long-term efficacy of the Incredible Years (IY) BASIC Parenting Programme delivered as a preventive intervention with parents of pre-school children who display signs of attention deficit hyperactivity disorder (ADHD) and conduct problems. Families were followed up after the completion of a controlled trial with 11 Sure Start areas in North and Mid-Wales and North West England. METHODS: Participants in the study were 50 pre-school children whose parents had received the intervention. Child ADHD symptoms were assessed at baseline, at follow-up one (6 months after baseline); at follow-up two (12 months after baseline); and at follow-up three (18 months after baseline). Families in the original waiting-list control group were not assessed after follow-up one as they had subsequently received the same intervention. RESULTS: The significant post-intervention improvements in child ADHD symptoms evident at follow-up one were maintained over time, as demonstrated by statistical and clinical stability of measures. No significant differences were found for ADHD symptoms across each follow-up, indicating that the gains made post intervention were maintained for at least 12 months, with 57% of the sample maintaining scores below the clinical cut-off on the Conners. Eighty-six, 58, and 30 per cent respectively had maintained at least a modest, large, or very large improvement in ADHD symptoms at follow-up three. CONCLUSIONS: Findings from this study suggest that the IY psychosocial treatment programme is a valuable intervention in the longer term for many pre-school children displaying early signs of ADHD.

The Leader Observation Tool: a process skills treatment fidelity measure for the Incredible Years parenting programme.

BACKGROUND: Despite recognition of the need to deliver evidence-based programmes in the field of mental health, there is little emphasis on implementing such programmes with fidelity. Attempts by programme developers to ensure adherence to their programmes include the development of training, manuals and content scales, but these alone may be insufficient to ensure fidelity in replication. Observational measures lend themselves as a potentially useful assessment of intervention outcomes, providing accurate and objective accounts of the intervention process. AIM: To develop a reliable and valid observational treatment fidelity tool of process skills required to deliver the Incredible Years (IY) BASIC parenting programme effectively. METHODS: An objective observational fidelity measure was developed to assess adherence to the IY BASIC parenting programme protocol. Observations were conducted on 12 IY BASIC parenting programme groups, attended by parents of pre-school children displaying signs of early onset conduct disorder. RESULTS: The Leader Observation Tool (LOT) achieved high internal reliability and good code-recode and inter-rater reliability. Evidence of concurrent validity was also obtained. CONCLUSIONS: Having demonstrated that the LOT is a reliable and valid measure of implementation fidelity, further research is necessary to examine the relationship between LOT scores and intervention outcome.

Exhaled nitric oxide; relationship to clinicophysiological markers of asthma severity.

Bronchial asthma is an airway disorder associated with bronchial hyperresponsiveness, variable airflow obstruction and elevated levels of nitric oxide (NO) in exhaled air. The variables all reflect, in part, the underlying airway inflammation in this disease. To understand their interrelationships we have investigated the relationship between exhaled NO levels and clinicophysiological markers of asthma severity. Twenty-six steroid naive atopic asthmatics participated in the analysis. All were given diary cards and were asked to record their peak expiratory flow (PEF) rates twice daily together with their asthma symptom scores and beta-agonist use. Diary cards were collected 2 weeks later and measurements of exhaled NO levels, FEV1 and histamine bronchial hyperreactivity (PC20 histamine) were undertaken. Exhaled NO levels were significantly higher in our study population than in normal control subjects and correlated negatively with PC20 histamine (r = -0.51; P = 0.008) and positively with PEF diurnal variability (r = 0.58; P = 0.002), but not with symptom scores, beta-agonist use of FEV1 (%). We conclude that a significant relationship exists between exhaled NO levels and the two characteristic features and markers of asthma severity, namely bronchial hyperreactivity and PEF diurnal variability. The lack of correlation between symptom score and beta-agonist use, of FEV1 (%) predicted and exhaled NO suggests that these measures are reflective of differing aspects of asthma.

The impact of group leaders' behaviour on parents acquisition of key parenting skills during parent training.

BACKGROUND: Parent training (PT) is identified as the most effective intervention for the treatment of conduct disorder (CD). Intervention observational outcomes are often reported as summarised composite scores, providing an overview of overall construct change. METHODS AND AIMS: Parents of children aged 3-5 years identified 'at risk' of developing CD were randomly allocated to either PT intervention or waiting list control group. Parent and child behaviours were assessed before and after the intervention period. The current paper aims to establish which individual observed parenting categories change as a result of PT, and which specific observed leader categories predict these changes. RESULTS: Controlling for baseline scores, ANCOVA demonstrated changes in parent praise and reflective behaviours as significant post-intervention. One-way ANOVAs demonstrated higher levels of leader praise and reflective behaviours resulted in greater change in parental praise and reflective behaviours respectively. Regression analyses indicated these leader behaviours predict positive change in parental praise and reflective behaviours for intervention families. CONCLUSIONS: Composite observational scores provide an account of behaviour constructs, whereas individual behaviour categories provide an insight into the core components of these constructs. The results suggest praise and reflection as key leader behaviours that influence the mechanisms of change in parenting behaviours as a result of PT.

Efficacy of the Incredible Years Basic parent training programme as an early intervention for children with conduct problems and ADHD.

BACKGROUND: The efficacy of the Incredible Years (IY) Basic parent training (PT) programme for a community-based sample of families with pre-school children at risk of developing both conduct problems and attention deficit hyperactivity disorder (ADHD) was examined. METHODS: Pre-school children displaying signs of both early-onset conduct problems and ADHD were randomly allocated to either IY PT intervention, or to a waiting list (WL) control group. Child symptoms were assessed before and after the intervention. RESULTS: Post intervention, the intervention group was associated with significantly lower levels of parent-reported inattention and hyperactive/impulsive difficulties, even after controlling for post-intervention changes in child deviance. In addition, 52% of those in the intervention condition, compared with 21% in the control condition, displayed clinically reliable improvements post intervention, giving an absolute risk reduction of 31% and a number needed to treat of 3.23. CONCLUSIONS: Findings from this study indicate that the IY PT programme is a valuable intervention for many pre-school children displaying early signs of ADHD.

Increasing access to clinical information on hospital wards.

Medical library information resources can make a positive contribution to the clinical information needs of health care professionals. To increase availability of knowledge-based information and transfer information to its point of use, a CD-ROM resource library was networked and interfaced with the existing hospital information system at Children's Hospital of Michigan in Detroit, Michigan. Clinicians in 21 patient care areas now have access to the patient record, full-text pediatric journal information and the Micromedex CCIS database at one location.
