Explaining the changeability and temporal stability of PAHCO
SECONDARY
The results of the analysis confirm the first research goal, which assumed changeability and temporal stability of PAHCO, by displaying a moderate to strong increase over the course of the WHPP as well as no decrease over the follow-up period of a total of 18 months.Our findings are in line with results on the changeability of PAHCO in a sample of secondary school students, which demonstrated a moderate effect for the increase of PAHCO following a physical education intervention [The findings of our study on temporal stability of PAHCO agree with theoretical research on PAHCO [With respect to the longer follow-up period in comparison with previous PAHCO interventions, our findings are supported by a meta-analysis of interventions addressing PA motivation, which showed stable intervention effects at follow-up time points beyond 6 months [In summary, the findings of our study on PAHCO’s changeability and temporal stability substantiate the theoretical assumptions of this model, largely in line with the existing literature and extend the current knowledge on PAHCO. These results might be of particular importance for future WHPPs, as interventions on PAHCO could lead to temporarily stable changes in PAHCO, which consequentially could promote HEPA and HRQOL in OWs. The potential of temporarily stable changes in PAHCO might present a specific benefit for OWs, as this target group is prone to insufficient levels of PA at low and moderate intensity and to longer periods of sedentary, work-related activities [
