Abstract

The impact of ISO/IEC 17025 accreditation in state public health laboratories (SPHLs) is understudied. There is a scarcity of research on SPHLs involving behavioral intent regarding ISO/IEC 17025 accreditation. The theory of planned behavior (TPB) was utilized to evaluate SPHL directors’ attitudes towards and intent to seek or maintain ISO/IEC 17025 accreditation. To test the questions of whether the three constructs of the TPB, attitude, subjective norms and perceived behavioral control are significant predictors of intent to seek or maintain ISO/IEC 17025 accreditation, and whether there are significant differences in these constructs towards the accreditation between SPHL directors based on accreditation status, an online survey was distributed to SPHL directors across the United States. Responses were analyzed using simple linear regression and multiple linear regression (n=37) and, Multivariate Analysis of Variance (MANOVA) and Analysis of Variance (ANOVA) (n=36). Results showed that there are significant differences between SPHL directors based on their accreditation status which is supported by the three constructs of TPB. These findings suggest that TPB constructs can play a positive and significant role in terms of SPHL directors’ intent to seek or maintain ISO/IEC 17025 accreditation, and SPHL directors who are involved in the accreditation have a favorable attitude toward it.
