This Cochrane‐Campbell systematic review examines the effects of group‐based parenting programmes on parents' psychosocial health. The review summarise findings from 48 studies conducted in various countries and settings including the USA, Canada, Australia, U.K., China, Germany, Japan, New Zealand and The Netherlands. The participants were adult parents with the parental responsibility for day‐to‐day care of children. A total of 4,937 participants were included in the studies. What are the main results? Parent training has positive short‐term effects on depression, anxiety, stress, anger, guilt, confidence and partner satisfaction. There was no effect on self‐esteem and none of the trials reported on aggression or adverse effects. However, after six months there are positive effects on only two outcomes (stress and confidence), and after one year there are no significant effects on any outcomes. The data refer primarily to mothers as there are limited data on fathers. Only one meta‐analysis was conducted for fathers, showing a statistically significant short‐term improvement in parental stress. There was no significant different in effects according to the type of programme or intervention duration. Abstract BACKGROUNDParental psychosocial health can have a significant effect on the parent‐child relationship, with consequences for the later psychological health of the child. Parenting programmes have been shown to have an impact on the emotional and behavioural adjustment of children, but there have been no reviews to date of their impact on parental psychosocial wellbeing. OBJECTIVESTo address whether group‐based parenting programmes are effective in improving parental psychosocial wellbeing (for example, anxiety, depression, guilt, confidence). SEARCH METHODSWe searched the following databases on 5 December 2012: CENTRAL (2011, Issue 4), MEDLINE (1950 to November 2011), EMBASE (1980 to week 48, 2011), BIOSIS (1970 to 2 December 2011), CINAHL (1982 to November 2011), PsycINFO (1970 to November week 5, 2011), ERIC (1966 to November 2011), Sociological Abstracts (1952 to November 2011), Social Science Citation Index (1970 to 2 December 2011), metaRegister of Controlled Trials (5 December 2011), NSPCC Library (5 December 2011). We searched ASSIA (1980 to current) on 10 November 2012 and the National Research Register was last searched in 2005. SELECTION CRITERIAWe included randomised controlled trials that compared a group‐based parenting programme with a control condition and used at least one standardised measure of parental psychosocial health. Control conditions could be waiting‐list, no treatment, treatment as usual or a placebo. DATA COLLECTION AND ANALYSISAt least two review authors extracted data independently and assessed the risk of bias in each study. We examined the studies for any information on adverse effects. We contacted authors where information was missing from trial reports. We standardised the treatment effect for each outcome in each study by dividing the mean difference in post‐intervention ...

Systematic reviews often provide recommendations for further research. When meta-analyses are inconclusive, such recommendations typically argue for further studies to be conducted. However, the nature and amount of future research should depend on the nature and amount of the existing research. We propose a method based on conditional power to make these recommendations more specific. Assuming a random-effects meta-analysis model, we evaluate the influence of the number of additional studies, of their information sizes and of the heterogeneity anticipated among them on the ability of an updated meta-analysis to detect a prespecified effect size. The conditional powers of possible design alternatives can be summarized in a simple graph which can also be the basis for decision making. We use three examples from the Cochrane Database of Systematic Reviews to demonstrate our strategy. We demonstrate that if heterogeneity is anticipated, it might not be possible for a single study to reach the desirable power no matter how large it is. Copyright © 2012 John Wiley & Sons, Ltd.
