Table 2 An overview of validation methodology and data used
Type of validity | Data source | Analytical approach |
|---|---|---|
Construct validity | • Qualitative interviews with maternal and newborn health workers (MNHWs) • Quantitative survey with MNHWs | • 10 qualitative interviews with MNHWs who appeared satisfied with their jobs, and five qualitative interviews with MNHWs who appeared dissatisfied. • Comparison of job satisfaction scores with the qualitative data. |
Content validity | • Qualitative interviews with MNHWs • Quantitative survey with MNHWs | • 10 qualitative interviews with MNHWs who appeared satisfied with their jobs, and five qualitative interviews with MNHWs who appeared dissatisfied. • Calculating the degree to which the items in each of the dimensions of the Job Satisfaction Survey were related to each other, using the Spearman’s rank correlation |
Reliability and internal consistency | • Quantitative survey with MNHWs | Calculating: • Cronbach’s alpha (α) coefficient of internal consistency • Theta (θ) coefficient (special case of Cronbach’s alpha) to specifically account for multidimensionality in an item set |
Sensitivity |  | • Created quartiles of the JSI to distinguish between different degrees of job satisfaction. • Tabulated the average JSI by socio-demographic characteristics of the MNHWs to see how this average score varied by different characteristics. |
