Weakness - original phase model outlined by Rollie and Duck is incomplete
Rollie and Duck states the process of breakdown of a relationship doesn't stop after grave-dressing.
there's a further step by which we move on to a new relationship, learning from previous one, trying not to do same things again.
named the 'resurrection phase'
ex-partners turn their attention to future relationships using experience gained from previous relationships.
Rollie and Duck make it clear progression from one phase to the next isn't inevitable and partners may return to an earlier phase.
Weakness - suggests Duck's model is a limited explanation as it doesn't account for dynamic nature of breakups with their uncertainty and complexity. Therefore, overall power of Duck's model is reduced.
Weakness - methodological issues within Duck's phase model
most research is retrospective.
ppts generally give their experiences of breakdown process, using interviews or questionnaires sometime after relationship has ended.
issue because giving feedback after breakup means what they recall may be inaccurate or unreliable.
some facts may be distorted or changed, or forgotten altogether.
Weakness - model doesn't necessarily describe how break-up happens IRL, weakening model's ability to present an accurate picture of relationship breakdown. Therefore validity and reliability of model is reduced.
Moghaddam et al suggests relationships in individualist cultures are mostly voluntary and end quite often.
However relationships in collectivist cultures are more frequently less easy to end, involve wider family and some cases are arranged with little involvement of partners.
Weakness - model assumes the breakup process is universal, which isn't the case. Therefore the model lacks validity.
