perceptions
about
any
social, economic or cultural biases in their volunteer base. The final
theme (motivations and barriers) focused on: (1) procedures for
dealing with the results; (2) perceptions around the motivations
of participants; and, (3) perceptions concerning any bias in their
volunteer base. Interviewees were encouraged to elaborate within
and
beyond
the
themes
wherever
possible.
The
telephone
inter-
views were conducted by the same researcher (Sarah Hobbs) to
minimise error due to interviewer variability (Bryman, 2008).

pro-

At
the

of
each
interview,
the
outline
of the study was again explained, and verbal consent sought to
record the interview. Interviews were recorded using a digital voice
recorder and transcribed after the event. We coded the transcripts
from each interview according to the three major themes (objec-
tives for running the scheme, types of participant and motivations
and
barriers)
using

because of its suitability for working with small sample sizes (Barry,

also a useful analytical aid because of the flexibility to visually map
out themes in the data, reflect on emerging themes and code key
concepts, generating theory that is grounded within the data (Barry,
1989; Basit, 2003). Using a grounded theory approach within the
