160 | Part 3 Lifestyle intervention
the lifestyle intervention program received questionnaires to evaluate the intervention program (tables 3.5.3-3.5.5), including the Patient Satisfaction Questionnaire (PSQ-18)274.

Additionally, a qualitative semi-structured interview was conducted among women in the intervention group (table 3.5.6).
Statistical analysis
Primary outcome of feasibility was the proportion of eligible women who completed the intervention. This best represents how many women who could receive lifestyle intervention were actually motivated to complete the intervention. The higher this proportion, the more feasible it would be to plan larger-scale studies to test effect of postpartum lifestyle intervention after complicated pregnancy and to offer lifestyle intervention – if effective - as usual care. The proportion of eligible women who completed the intervention was defined as:
nComnpleted study = ∗ h = ∗ (1 − ) Eligible
Participation rate was defined by the number of women who agreed to participate in the study divided by the total of women who were eligible for participation. Based on other studies in primary lifestyle interventions275 276, a participation rate of 15% was expected. Adherence was defined by the number of women who attended the 13-months visit divided by the number of women who agreed to participate in the study. Based on other studies in primary lifestyle interventions in fertile women60 an adherence of 75% was expected. Based on these numbers, the lifestyle intervention was found to be feasible if the
