Although change may be difficult to achieve, an intervention to improve the quality of maternity care could be rewarding, as observed in other studies in Uganda [ 25].
The most effective course of action emerges with time through experimentation and learning during which innovations are adapted locally in an active process of achieving an "intervention-system fit" [ 10].
One study with 96 overweight and obese children, which was based on a lifestyle intervention, achieved a treatment effect on the reduction of % BF (95 % CI = −3.31 to −1.55) [ 39].
In this paper, we take a first step toward addressing the challenging but important question of whether a positive impact on four specific student problem solving beliefs, which are common and counterproductive, can be achieved with an intervention of short duration.
Significant improvements were achieved with an intervention.
Similarly, Moffitt et al. [ 48] observed a change in behavior achieved by an intervention that targeted knowledge and attitude only.
Significant improvements were achieved with an intervention of environmental space reorganization and process management, access control, staff education and training, and encouraging ethics consultation.
Another limitation of the included studies is the lack of blinded interventions, but it is important to remember that the very nature of the behavioural interventions in many cases impede efforts to achieve a blind intervention.
Another problem that uses the concept of logical steady states is the identification of sets of interventions (an intervention representing logical values fixed to a certain value thus corresponding to knockouts or constitutive activations) to achieve a predefined intervention goal, for example, a certain phenotypic response of the cell [ 10, 98].
All six interventions that achieved an improvement in health outcome were multi-faceted in nature, delivering more than one component.
