Dear Wendy,
the only comment that springs to my mind is that convenience samples, as
based on working mothers' preferences, may misrepresent 2. managers and 3.
other employee working in the same office/workspace or sharing
responsibilities with the nursing woman.

However, I do not know how much this problem will affect your research, for
which I wish you all the best.

Kindest regards,
Carlo

Dear Statalist member:

I am working on my thesis proposal regarding breastfeeding in the workplace.

I will be collecting data from three three different groups. I will be
interviewing women (probabilistic sample) and then asking them to provide a
name to build the other two groups (convenience sample). Groups to obtain
data from: 1. working mothers; 2. managers; 3. other employee working in the
same office/workspace or sharing responsibilities with the nursing woman.

Working mothers sample will be obtained from a database provided by a HR
department in the academic setting I am working at. Then I will ask the
mothers in the sample to recommend their immediate manager name and also the
closest employee working with her (example: sharing office).

Hypothesis: Is workplace support influencing the breastfeeding intention and
also the breastfeeding duration?

Variables: sociodemographic, manager support, colleagues support,
institutional policies, etc.

Questionnaires: I will be sending a separate self-administered questionnaire
to the groups. One designed for women (it was already validated). Managers
and colleagues will be receiving another one.

What is the best approach to integrate the three sets of data into one
analysis? Is the proposed sampling ok?

Thank you in advance,
