participants’ names and addresses, which they printed on to postal labels. The researcher then visited the department and sent out a participant pack to all potential participants. At no point did the researcher take any client identifiable information out of the LA social care buildings. Participant packs included an information letter (appendix 8), two consent forms (appendix 9) and one of each of the research questionnaires described above. Participants were asked to return the completed questionnaires in a pre-paid envelope or via their social worker/support staff. Four packs were returned without the consent forms having been completed, however as the participant had completed and returned all the remaining questionnaires, their consent to their data being included in the present research study was assumed. Five weeks after posting the original research packs to participants, the researcher returned to the social care department and sent out a reminder letter (appendix 10) to all potential participants. Again this was achieved by the LA preparing the relevant postage labels. Effect Size Calculation Assuming a medium effect size of f2 = 0.15, a significance of 0.05, 3 tested predictors (secure, avoidant and ambivalent attachment styles), an estimated total sample size of 77 is required to achieve 80% power. A large effect size f2 = 0.35 would require an estimated sample size of 36 to achieve 80% power.
