Appendix D Gaps in the evidence
The Programme Development Group (PDG) identified a number of gaps in the evidence related to the programmes under examination based on an assessment of the evidence. These gaps are set out below.
1. There is little UK evidence about the effectiveness of interventions in this field.
2. There is little evidence about the effectiveness of services and interventions for socially deprived young people, or evidence that searches for a differential effect among different groups of young people.
3. There are few UK data about the cost effectiveness of contraceptive service provision.
The Group made 5 recommendations for research. These are listed in section 5.
