Dear Michael,

try the following dissertation:

Barbara Brown (2003): Employees’ Organizational Commitment and Their Perception of Supervisors’ Relations-Oriented and Task-Oriented Leadership Behaviors.

This research study deals with "employees organizational commitment". Three types of organizational commitment are identified, namely affective, continuance and normative commitment (see pp. 30ff.). Research work, involving affective, continuance and normative commitment is described (see pp. 31ff.). One aim of this dissertations exists in examining these different types of organizational commitment.

For this purpose several Organizational Commitment Questionnaires (OCQ) are described (see pp. 40ff.), for example:

Porter’s et al. (1974) Organizational Commitment Questionnaire (OCQ) and

Meyer & Allen’s (1997) Organizational Commitment Questionnaire (OCQ)

I assume, if you've got a look at these questionaires, you'll find general items and scales, in order to measure organizational commitment. Research findings are also represented (see pp. 50ff.)

For your thorough overview, try:

With Marianne Milmeister I developped a well-being indicator using HBSC data. You find a presentation I made in 2009 at a Conference in Amsterdam, see my publications on ResearchGate.

I see variations on the topic of how to create a scale so frequently that I've just created a new thread that will hopefully collect resources in this area:

https://www.researchgate.net/post/How_to_help_people_create_simple_scales

And I do like the DeVellis book for those who want to learn both "why to" create scales and "how to" do it, but it is a bit conceptual for someone who simply needs to create one scale for a specific study.

Research Methodology by Douglas & Lind, Even Blacks book is good
