A Qualitative Study on the Content Validity of the Social Capital Scales in the Copenhagen Psychosocial Questionnaire (COPSOQ II)

The Copenhagen Psychosocial Questionnaire (COPSOQ II) includes scales for measuring workplace social capital. The overall aim of this article is to evaluate the content validity of the following scales: horizontal trust, vertical trust and justice based on data from cognitive interviews using a think-aloud procedure. Informants were selected to achieve variation in gender, age, region of residence, and occupation. A predetermined coding scheme was used to identify: 1) Perspective (reflection on behalf of oneself only or abstraction to a broader perspective), 2) Use of response options, 3) Contexts challenging the process of answering, and 4) Overall reflections included in the retrieval and judgement processes leading to an answer for each item.

The results showed that 1) the intended shift from individual to a broader perspective worked for eight out of eleven items. 2) The response option balancing in the middle covered different meanings. Retrieval of information needed to answer constituted a problem in four out of eleven items. 3) Three contextually challenging situations were identified. 4) For most items the reflections corresponded well with the intention of the scales, though the items asking about withheld information caused more problems in answering and lower content validity compared to the other items of the scales. In general, the findings supported the content validity of the COPSOQ II measurement of workplace social capital as a group construct. The study opens for new insight into how concepts and questions are understood and answered among people coming from different occupations and organizational settings.
