The Q&A section produced several pointed methodological challenges. On three factors but five stages: a questioner asked why the structure measured three factors (action, contemplation, precontemplation) but identified five discrete stages of change. Coppin explained that one stage (maintenance) was inappropriate for the unemployment context (it presupposes already having and keeping a job), and that "preparation" emerged from intermediate scoring patterns rather than being a discrete factor.
On positive versus negative behaviour change: a questioner observed that most stage-of-change literature concerns getting people to stop doing something (smoking, drinking) rather than start doing something (jobseeking). Coppin acknowledged this as a significant theoretical issue the thesis would need to address.
On the active control problem: the most pointed challenge, to validate stage-specific intervention effects, the methodology needs to randomly assign people to interventions across different stages. Coppin acknowledged the design did not include this and that government partners would not permit randomisation across stages on ethical grounds (it would mean deliberately giving inappropriate interventions to some participants).
On the comparison with theory of planned behaviour: a questioner raised whether Ajzen's Theory of Planned Behaviour offered a more parsimonious framework. Coppin acknowledged the conceptual overlap, particularly around intention strength.
On integrating the Australian Job Seeker Classification Instrument: a questioner asked how Coppin's intrinsic measures would be combined with the existing extrinsic Australian government Job Seeker Classification. Coppin's response: the data systems track this and the extrinsic-intrinsic combination produced a striking finding, that 36% of jobseekers classified as "Stream 1" (closest to employment) were actually in precontemplation or contemplation, while 34% of "Stream 4" jobseekers (furthest from employment) were genuinely in action stage. The conventional government model was systematically misallocating intervention resources.
On training quality control across 200 advisors: Coppin acknowledged this as a real methodological constraint, mitigated through detailed scripts, recorded videos with end-of-training tests, observation guides for managers, and reliance on employment service providers to track delivery.
On reassessment over time: a questioner noted that participants' stage-of-change might shift over six months. Coppin acknowledged this as a study limitation imposed by the agreement with government partners, who would only fund a single assessment.
