Interventions for promoting reintegration and reducing harmful behaviour and lifestyles in street-connected children and young people

Background
Numbers of street-connected children and young people run into many millions worldwide and include children and young
people who live or work in street environments. Whether or not they remain connected to their families of origin, and despite many strengths and resiliencies, they are vulnerable to a range of risks and are excluded from mainstream social structures and opportunities.

Objectives
To summarise the effectiveness of interventions for street-connected children and young people that promote inclusion
and reintegration and reduce harms. To explore the processes of successful intervention and models of change in this area, and to understand how intervention effectiveness may vary in different contexts.

Selection criteria
The review included data from harm reduction or reintegration promotion intervention studies that used a comparison group
study design and were all randomised or quasi-randomised studies. Studies were included if they evaluated interventions
aimed to benefit street-connected children and young people, aged 0 to 24 years, in all contexts.

Data collection and analysis
Two review authors independently extracted data and assessed the risk of bias of included studies. Data were extracted on intervention delivery, context, process factors, equity and outcomes. Outcome measures were grouped according to whether they measured psychosocial outcomes, risky sexual behaviours or substance use. A meta-analysis was conducted for some outcomes though it was not possible for all due to differences in measurements between studies. Other outcomes were evaluated narratively.

Main results
We included 11 studies evaluating 12 interventions from high income countries. We did not find any sufficiently robust
evaluations conducted in low and middle income countries (LMICs) despite the existence of many relevant programmes.
Study quality overall was low to moderate and there was great variation in the measurement used by studies, making
comparison difficult. Participants were drop-in and shelter based. We found no consistent results on a range of relevant
outcomes within domains of psychosocial health, substance misuse and sexual risky behaviours despite the many
measurements collected in the studies. The interventions being evaluated consisted of time limited therapeutically based programmes which did not prove more effective than standard shelter or drop-in services for most outcomes and in most studies. There were favourable changes from baseline in outcomes for most particpants in therapy in terventions and also in standard services. There was considerable heterogeneity between studies and equity data were inconsistently reported. No study measured the primary outcome of reintegration or reported on adverse effects. The review discussion section included consideration of the relevance of the findings for LMIC settings.

Authors' conclusions
Analysis across the included studies found no consistently significant benefit for the 'new' interventions compared to standard services for street-connected children and young people. These latter interventions, however, have not been rigorously evaluated, especially in the context of LMICs. Robustly evaluating the interventions would enable better recommendations to be made for service delivery. There is a need for future research in LMICs that includes children who are on the streets due to urbanisation, war or migration and who may be vulnerable to risks such as trafficking.
