Background
Levitas [1998] distinguished among several discourses about persons outside the labour market. The moral underclass discourse (MUD) implies a view of social assistance recipients as lazy. If the welfare benefits are too generous, they will have no motivation to seek employment. This discourse is closely tied to a paternalistic discourse (PAD) in which the welfare bureaucracy must impose strict work requirements [Dahl, 2003]. It also blames the welfare recipiency on the individual client. In Europe, there has been more recognition of structural causes of welfare recipiency, such as lack of jobs. The state has an obligation to provide jobs, and the clients are expected to take the available jobs. So the relationship between the individual and the state is one of reciprocity. Levitas labelled this the social integrationist discourse. Seen from this perspective, the compulsory work programs, sanctioning, and time limits on cash assistance that are studied in the present review, imply that the problem of long-term social recipiency is described using the MUD and the solution is described using the PAD [Dahl, 2003].
There are at least three theories about mediating variables: (1) maintenance and teaching of skills (vocational and social); (2) strengthening of motivation and work morale; and (3) strengthening of self-efficacy. It is difficult to compare effects of interventions across different countries. Generally, effects vary not only with the nature of the intervention, but also who participate, the conditions of the local labour market, and how other welfare institutions are shaped and organised.
Objectives of this review
To study the effects of work programmes for welfare recipients on work status, earnings, welfare receipt, and total income To explore subgroup differences. The review will try to identify approaches that appear to be more or less effective overall and, to the exent that adequate data are available, for subgroups. To identify any adverse effects of such programmes (e.g. displacement or negative effect in income or work status).
Methods
Criteria for inclusion and exclusion of studies for this review
Study design
Studies using the following designs are eligible for a quantitative review on the effects and impacts of work programmes for welfare recipients: Randomised controlled trials (RCTs) Cluster randomised trials Quasi randomised trials
Studies using the following designs will be collected, listed, and described in an explorative review of associations among participation in work programmes and various outcomes: Non-randomised concurrently controlled studies (two groups assigned by the investigators and dependent variables measured on both groups before and after the intervention) Cohort studies (two groups defined by the interventions and dependent variables measured on both groups before and after the intervention).
We will not restrict country of publication. There will be no language restrictions.
Participants
Welfare recipients who are potentially able to take part in some kind of work. We will exclude persons entitled to unemployment benefit and persons with pensions of any kind. If only some participants in the study are welfare recipients, the study is only included if at least 50% receive welfare benefit.
Interventions
Interventions intended to help welfare recipients become self-sufficient typically come as “packages” involving several components. Therefore, it is usually not possible to measure the effect of work experience apart from the effect of the other components of the program. We include interventions that offer
The term “time limited work experience” needs some clarification. First, the work experience is not a steady job. The duration of the work must be explicitly stated. This duration will be recorded for each study. Second, the work must not involve a job acquired through channels external to the program under evaluation. In other words, the job must be program generated.
Control/comparison groups
The main control comparison would be a group of persons receiving ordinary (passive) social economic assistance. If possible, the relative efficacy would be considered by comparing two different work programmes.
Outcome measures
All outcomes will involve a comparison between different groups. The comparisons will be either post intervention measures or change scores (difference between post- and pre scores). Accepted sources of outcome data will be register data, recordings by program personnel or employers and self-reports. Each data source has strengths and limits. Whereas register data are relatively free from recall- and expectancy biases, they will miss e. g. employment in jobs that are not reported to the authorities. The type of data source will be recorded for each study.
PRIMARY OUTCOMES
proportion of attendants who obtain competitive work (= work with standard wages and which anyone can apply for). duration of employment during a given time interval. elapsed time until obtained work duration on welfare benefit during a given time interval (as above)
mean or median earnings at different time points total individual earnings (e.g., income + social insurance + social assistance + welfare benefit) total household earnings
SECONDARY OUTCOMES
quality of life social skills self confidence social activity, participation and integration
crime drug and alcohol use displacement (when program participants get jobs, this worsens the chances of non-participants to get jobs) decrease in combined income other
Because duration of follow-up is expected to vary across studies, the exact duration of follow-up will be recorded for each study. After data collection is finished, duration times can be analysed based on the available data. They can for example be grouped into short, medium and long follow-up durations.
Search strategy for identification of relevant studies
We will search the following databases: C2-SPECTR, CENTRAL, MEDLINE, EMBASE, PsycINFO, Sociological Abstracts, Cinahl, Caredata, BIBSYS, SIGLE (for grey literature), IBSS, and Social Science Citation Index, with no restriction on publication date.
We will use the same text words across all databases and use the specialised controlled vocabularies for each database. The search strategy will be iterative, i.e. new search terms will surface as the reports accumulate.

Criteria for evaluating eligibility of retrieved studies
Two reviewers will independently scan the abstracts and titles of retrieved reports for eligibility, according to the inclusion criteria above. Full copies of all those deemed eligible by one of the reviewers will be retrieved for closer examination (item 3 below). Consensus will be reached by discussion and consultation with a third reviewer, if necessary. All studies which initially appeared to meet the inclusion criteria but, based on the full text reports, do not meet the inclusion criteria will be detailed in the table of excluded studies (item 7 below).
Quality assessments
We will assess components that contribute to the measured effectiveness of interventions. Two reviewers will independently assign each selected study to quality categories described below. Uncertainty or disagreement is solved by discussion with a third reviewer.
Generation of allocation sequence
Concealment of allocation sequence
Control of initial difference in prognostic factors between groups
In a properly randomised study, all initial differences between groups will be caused by chance. This applies to all prognostic variables, both known and unknown. But in non-randomised designs, there may be important initial differences between groups. These differences can be systematic, and they can appear in unmeasured variables as well as in the measured ones. It is generally possible to control for the latter but not the former. Matching can be used before the intervention to make groups more similar, and regression methods can be used after the intervention to control for initial differences, but all these methods may introduce bias in the results [
Prevention of Performance Bias
Prevention of Detection Bias
MET = Assessor unaware of the assigned treatment when collecting outcome measures. Also score as met if outcome is questionnaire data or register data.
Prevention of Attrition Bias
Intention-to-treat
Data management and extraction
Two reviewers will independently extract information from the full text report on study characteristics using a specially designed pretested data extraction form. For cases in which outcome information is missing from the original reports, attempts will be made to retrieve the necessary data for the analysis from the original investigators. Inter-rater agreement (i. e. coding reliability) will be assessed and reported as Kappas. The rate of agreement will be reported separately for all items to avoid inflation with study characteristics that generally achieve perfect agreement (e. g. year of publication). Disagreements will be resolved by meeting and discussing coded items. Data will be entered into Comprehensive Meta-Analysis [Borenstein & Rothman, 1999].
Data synthesis
Continuous data
Continuous measures (e.g., earnings) will be calculated as weighted mean differences if all outcomes are reported on the same scale of measurement and standardised mean differences when results are reported on different scales. We will report the 95% confidence intervals for all of the above.
Discrete outcomes
We will express binary outcome measures (e.g., employed/unemployed) as risk ratios (relative risks). In some cases, it might also be feasible to report the number needed to treat (NNT).
Identifying heterogeneity
We will use the following methods to assess heterogeneity Common sense (e. g. are the interventions, participants or outcomes so different that they cannot be combined?) This will be based on a synthesis of the process elements. Chi-square test for heterogeneity (p<0.10) and I-Squared. Visual examination of graphs for outliers and between study differences.
Exploring heterogeneity
If heterogeneity is judged to be large on the basis of (1)-(3), we will examine potential sources using the following steps: Subgroup analysis Meta-regression Sensitivity analysis
Subgroup analysis
We will consider subgroup analysis across the following factors: unemployment level in the study area, placement in the private or public sector, direct placement or prevocational training, type, intensity or length/period of the intervention.
Meta-regression
If useful, and after consultation with a statistician, we will conduct meta-regression to look at the relation of size of effect to characteristics of the trials.
Sensitivity Analysis
Sensitivity analysis will be used to evaluate whether the pooled effect sizes are robust across components of methodological quality. For methodological quality, we will consider sensitivity analysis for each major component of the quality checklists.
Fixed vs. Random Effects Models
We will use random effects models when heterogeneity cannot be explained by subgroup analysis or meta-regression, and when we also want to be able to generalise the findings to a universe of similar (unobserved) studies as the obtained sample. Fixed effects models will be used either if heterogeneity is ignorable or when we only want to summarise the data for the obtained studies (i.e. we do not aim to generalise).
Criteria for determination of independent findings
In many instances, several different outcome data are measured on the same subjects in the primary studies (e.g. employment status and earnings). Sometimes the same outcome is measured at multiple points in time. Because these data are from the same sample of participants, and, therefore, are not independent estimates of treatment effect, we will analyse the data in such a way that any one analysis will contain a single outcome from a single point in time.
Details of study coding categories
Statistical procedures and conventions
Results will be analysed using Comprehensive Meta-Analysis software [Borenstein & Rothman, 1999]. Prognostic variables will be used in analyses if there are less than or equal to 20% missing data. Graphical presentations of effects will be produced using Comprehensive Meta-Analysis.
Timeframe
Plans for updating the review
Searches will be performed every two years after publication of the full review. Results of searches will be published and classified either as (1)
