Personal development groups (PD groups) are widely employed in counsellor training with the aim of developing the self-awareness of trainee counsellors, and the intention of this paper is to open a discussion forum of the use of these groups and understand their use more fully. A quantitative and qualitative approach was employed in this study, using focus groups with a cross section of 88 trainees of counselling, at different points in their training, to establish those factors that were felt to contribute to developing self-awareness in the group. A questionnaire was used to measure both trainees' perceptions of their own self-awareness and the extent to which the contributory factors were felt to be both present and helpful in their current PD group (this is referred to as the "comfort fit"). Statistical findings, from the full cohort of 88 trainees, indicated that they were more comfortable in the PD group at the start of their training and less comfortable at the end, although there was no clear relationship between there being a better "comfort fit" and increased self-awareness. These findings are discussed in relation to alternative methods of facilitating the self-awareness of trainees of counselling (such as mandatory personal therapy) alongside the associated complexities of undertaking research of this kind.
