Understanding the relationship between family income and conduct problems: findings from the mental health of children and young people survey.

BACKGROUND: Children from low-socioeconomic backgrounds exhibit more behavioural difficulties than those from more affluent families. Influential theoretical models specify family stress and child characteristics as mediating this effect. These accounts, however, have often been based on cross-sectional data or longitudinal analyses that do not capture all potential pathways, and therefore may not provide good policy guidance. METHODS: In a UK representative sample of 2399 children aged 5-15, we tested mediation of the effect of household income on parent and teacher reports of conduct problems (CP) via unhealthy family functioning, poor parental mental health, stressful life events, child physical health and reading ability. We applied cross-lagged longitudinal mediation models which allowed for testing of reciprocal effects whereby the hypothesised mediators were modelled as outcomes as well as predictors of CP. RESULTS: We found the predicted significant longitudinal effect of income on CP, but no evidence that it was mediated by the child and family factors included in the study. Instead, we found significant indirect paths from income to parental mental health, child physical health and stressful life events that were transmitted via child CP. CONCLUSION: The results confirm that income is associated with change in CP but do not support models that suggest this effect is transmitted via unhealthy family functioning, parental mental health, child physical health, stressful life events or reading difficulties. Instead, the results highlight that child CP may be a mediator of social inequalities in family psychosocial functioning.

Prospective evaluation of quality of life in children treated in UKALL 2003 for acute lymphoblastic leukaemia: A cohort study.

BACKGROUND: Health-related quality of life (HRQoL) from diagnosis until end of treatment for children with acute lymphoblastic leukaemia was investigated, examining effects of age, gender, risk-stratified treatment regimen, and therapy intensity (one vs. two 'delayed intensifications' [DIs]). METHOD: In a multi-centre prospective study, parents reported their child's generic and disease-specific HRQoL and their own care-giving burden at five time points. From 1,428 eligible patients, 874 parents completed questionnaires at least once during treatment. RESULTS: At each time point, generic HRQoL was significantly lower than equivalent norm scores for healthy children. HRQoL decreased significantly at the start of treatment, before recovering gradually (but remained below pre-treatment levels). Parents reported that older children worried more about side effects and their appearance, but showed less procedural anxiety than younger children. Concern for appearance was greater among girls than boys. Compared to Regimen B (i.e. additional doxorubicin during induction and additional cyclophosphamide and cytarabine during consolidation chemotherapy), patients receiving Regimen A had fewer problems with pain and nausea. There were no statistically significant differences in HRQoL by number of DI blocks received. INTERPRETATION: HRQoL is compromised at all stages of treatment, and is partly dependent on age. The findings increase understanding of the impact of therapy on children's HRQoL and parental care-giving burden, and will contribute to the design of future trials.

Psychometric properties of the Hospital Survey on Patient Safety Culture: findings from the UK.

BACKGROUND: Patient safety culture is measured using a range of survey tools. Many provide limited data on psychometric properties and few report findings outside of the US healthcare context. This study reports an assessment of the psychometric properties and suitability of the American Hospital Survey on Patient Safety Culture for use within the UK. METHODS: A questionnaire survey of three hospitals within a large UK Acute NHS Trust. 1437 questionnaires were completed (37% response rate). Exploratory factor analysis, confirmatory factor analysis and reliability analyses were carried out to assess the psychometric performance of this survey instrument and to explore potential improvements. RESULTS: Reliability analysis of the items within each proposed scale showed that more than half failed to achieve satisfactory internal consistency (Cronbach's α<0.7). Furthermore, a confirmatory factor analysis carried out on the UK data set achieved a poor fit when compared with the original American model. An optimal measurement model was then constructed via exploratory and confirmatory factor analyses with split-half sample validation and consisted of nine dimensions compared with the original 12 in the American model. CONCLUSION: This is one of the few studies to provide an evaluation of an American patient safety culture survey using data from the UK. The results indicate that there is need for caution in using the Hospital Survey on Patient Safety Culture survey in the UK and underline the importance of appropriate validation of safety culture surveys before extending their usage to populations outside of the specific geographical and healthcare contexts in which they were developed.

Use of a safety climate questionnaire in UK health care: factor structure, reliability and usability.

AIM: To explore the factor structure, reliability, and potential usefulness of a patient safety climate questionnaire in UK health care. SETTING: Four acute hospital trusts and nine primary care trusts in England. METHODS: The questionnaire used was the 27 item Teamwork and Safety Climate Survey. Thirty three healthcare staff commented on the wording and relevance. The questionnaire was then sent to 3650 staff within the 13 NHS trusts, seeking to achieve at least 600 responses as the basis for the factor analysis. 1307 questionnaires were returned (36% response). Factor analyses and reliability analyses were carried out on 897 responses from staff involved in direct patient care, to explore how consistently the questions measured the underlying constructs of safety climate and teamwork. RESULTS: Some questionnaire items related to multiple factors or did not relate strongly to any factor. Five items were discarded. Two teamwork factors were derived from the remaining 11 teamwork items and three safety climate factors were derived from the remaining 11 safety items. Internal consistency reliabilities were satisfactory to good (Cronbach's alpha > or =0.69 for all five factors). CONCLUSIONS: This is one of the few studies to undertake a detailed evaluation of a patient safety climate questionnaire in UK health care and possibly the first to do so in primary as well as secondary care. The results indicate that a 22 item version of this safety climate questionnaire is useable as a research instrument in both settings, but also demonstrates a more general need for thorough validation of safety climate questionnaires before widespread usage.

Quality of life implications as a consequence of surgery: limb salvage, primary and secondary amputation.

Purpose. We investigated self-reported quality of life (QoL), body image and daily competence of patients as a consequence of limb salvage surgery (LSS), primary or secondary amputation, and the views of patients following secondary amputation.Patients. Patients (n=37) had all been treated for osteosarcoma or Ewing's sarcoma in the lower limb.Methods. QoL was measured by questionnaire. A separate interview to determine satisfaction with decision-making was conducted with those treated for secondary amputation.Results. For the total group, QoL was below that expected from population norms. There were no differences in QoL between those undergoing LSS surgery compared with amputation. However, LSS reported better daily competence and were less likely to use a walking aid. For the total group, body image and daily competence were associated with better QoL.Discussion. All these patients are at risk of compromised QoL following surgery. Our data are in line with previous work suggesting outcomes may be better for LSS compared with amputation. Following secondary amputation, most patients (80%) did not regret initial LSS treatment, but felt that the time gained allowed them to come to terms with subsequent surgery.
