Background. Although self-help interventions are effective in treating depression, less is known about the factors that determine effectiveness (i.e. moderators of effect). This study sought to determine whether the content of self-help interventions, the study populations or aspects of study design were the most important moderators.

BackgroundChildren of parents with mental disorder face multiple challenges.AimsTo summarise evidence about parental mental disorder and child physical health.MethodWe searched seven databases for cohort or case–control studies quantifying associations between parental mental disorders (substance use, psychotic, mood, anxiety, obsessive–compulsive, post-traumatic stress and eating) and offspring physical health. Studies were excluded if: they reported perinatal outcomes only (<28 days) or outcomes after age 18; they measured outcome prior to exposure; or the sample was drawn from diseased children. A meta-analysis was conducted. The protocol was registered on the PROSPERO database (CRD42017072620).ResultsSearches revealed 15 945 non-duplicated studies. Forty-one studies met our inclusion criteria: ten investigated accidents/injuries; eight asthma; three other atopic diseases; ten overweight/obesity; ten studied other illnesses (eight from low-and middle-income countries (LMICs)). Half of the studies investigated maternal perinatal mental health, 17% investigated paternal mental disorder and 87% examined maternal depression. Meta-analysis revealed significantly higher rates of injuries (OR = 1.15, 95% CI 1.04–1.26), asthma (OR = 1.26, 95% CI 1.12–1.41) and outcomes recorded in LMICs (malnutrition: OR = 2.55, 95% CI 1.74–3.73; diarrhoea: OR = 2.16, 95% CI 1.65–2.84). Evidence was inconclusive for obesity and other atopic disorders.ConclusionsChildren of parents with mental disorder have health disadvantages; however, the evidence base is limited to risks for offspring following postnatal depression in mothers and there is little focus on fathers in the literature. Understanding the physical health risks of these vulnerable children is vital to improving lives. Future work should focus on discovering mechanisms linking physical and mental health across generations.Declaration of interestNone.

Children's health policy has highlighted the need to develop self-care programmes. However, there is a lack of evidence on which to base the development of such programmes. This paper reviews the published research on the effectiveness of self-care support interventions for children and young people with asthma, cystic fibrosis and diabetes. A systematic search was conducted of a range of electronic databases, supplemented by searching the reference lists of retrieved papers and published reviews. Retrieved studies were assessed against quality and eligibility criteria by two independent reviewers. The results were narratively synthesized to examine the effectiveness of self-care support interventions on health status, psycho-social well-being, condition-related knowledge, health service use and participant satisfaction. The search strategy identified 4261 papers which were screened against the review inclusion criteria. A total of 194 papers were assessed as being potentially eligible for inclusion with 15 papers being judged as adequate to include in the review. There is strong evidence of the effectiveness of interventions that target children/young people; use e-health or group-based methods; that are delivered in community settings. There is no evidence that interventions that focus on parents alone or are delivered only in hospital settings are effective. While there is some evidence to inform the development of self-care support programmes, there is a need for well-designed trials of interventions that are feasible to transfer into real-life settings and which involve parents and children in their development.

Background: Current guidelines for the management of depression suggest the use of guided selfhelp for patients with mild to moderate disorders. However, there is little consensus concerning the optimal form and delivery of this intervention. To develop acceptable and effective interventions, a phased process has been proposed, using a modelling phase to examine and develop an intervention prior to preliminary testing in an exploratory trial. This paper (a) describes the modelling phase used to develop a guided self-help intervention for depression in primary care and (b) reports data from an exploratory randomised trial of the intervention.
