APIM analysis
The results of the APIM analysis are depicted in Fig. Results of APIM analysis. Time 0 is baseline data collection and time 1 is data collection immediately post-interventionIn an APIM model, the joint effect, or the additive effect of both actor and partner baseline HHI score on follow-up actor HHI score, differs depending on the level and direction of baseline scores. The mean HHI scores at baseline and follow-up of both caregivers and PLWS are displayed in Table Mean total Hopefulness score, by Time, in PLWS & CaregiversTable Model predicted follow-up HHI Total score values for hypothetical values of baseline actor and partner HHI Total scores for a PLWS in the intervention (KUPAA) trial armPartner effects for caregivers and patients. Predicted patient HHI Total score at post-intervention follow-up by changes in caregiver baseline score, holding patient baseline HHI Total score at its observed mean (left panel); and predicted caregiver HHI Total score at post-intervention follow-up by changes in patient baseline score, holding caregiver baseline HHI Total score at its observed mean (right panel)
