MI is more effective when delivered across a series of sessions, rather than as a one-off intervention; the 2012 review by Carney and Myers (2012) included nine studies of MI in adolescent populations, concluding that individual interventions across multiple sessions had the strongest effect.
Lifestyle risk factors need to be tackled at multiple levels including individual intervention provided by health professionals as well as through population health approaches.
Evidence from previous systematic reviews included in the scoping of this project supports high effectiveness of structural [ 43] and multifaceted interventions focusing on multiple targets, compared to single and individual interventions [ 44].
The most effective interventions were postpartum (instead of antenatal) individual interventions (instead of group interventions) aimed at women with multiple risk factors (instead of offering it to all women).
Culturally sensitive screening and intervention approaches for marijuana use among adolescent girls should address multiple individual, relationship and community factors, in order to prevent unwanted pregnancy as well as to reduce marijuana use during this vulnerable time.
Multiple interventions will combine to produce incremental benefit in outcomes, such as those seen in the EPICure studies, 16 but individual interventions may produce benefits that are undetectable in terms of 2-year outcomes.
Numerous studies of successful individual interventions to manage communicable disease determinants in various types of communities have been published, but few have applied multiple interventions in an integrated, coordinated manner.
Also, multiple simultaneous interventions are more likely to be effective than any individual intervention alone [7].
Of note, older adults with type 2 diabetes showed greater improvement in the group interventions than in the individual intervention over time, with Bonferroni correction used for multiple test comparison (P = 0.011).
Multiple loci are sequenced for multiple individuals and species.
