Psychometric assessment of the Persian version of short clinical scale to measure chemotherapy-induced nausea and vomiting: the MASCC antiemetic tool

Psychometric Properties of the Persian Version of the Personal Meaning Profile in Iran

The Personal Meaning Profile (PMP) is a widely used instrument to measure people's perceptions of personal meaning in their lives. This study aimed to evaluate the psychometric properties of the Persian version of the PMP. First, the researchers developed the Persian version of this scale using the forward-backward procedure. Then, they examined the face and content validities by both qualitative and quantitative approaches. To evaluate the construct validity, researchers administered the instrument to a sample of 482 medical sciences students and performed exploratory and confirmatory factor analyses. The reliability was assessed using loading factors, Cronbach's alpha coefficients, and composite reliability. An average scale-level of content validity index of the PMP with 57 items was 0.80. The findings revealed that the Persian version of the PMP comprises five factors explaining 50.57% of the total variance. The confirmatory factor analysis indices showed a moderate fit for the data. Reliability of the Iranian version of PMP was demonstrated with a Cronbach's alpha of 0.893. Consistency was established with test-retest reliability with an interval of 2 weeks (Intracluster Correlation Coefficient = 0.983, p < 0.001). Moreover, the criterion validity demonstrated a significant inverse relationship between the PMP and General Health Questionnaire (r = - 0.34, p < 0.001). This study indicated that the Persian version of the PMP is an acceptable, reliable, and valid measurement to evaluate the meaning in life in Iranian medical sciences students.

Psychometric properties of the Persian version of Instrument of Professional Attitude for Student Nurses (IPASN)

Aim

To evaluate nursing students’ professionalism attitude, it is necessary to use a validated and reliable instrument.

Design

This study aimed to develop the Persian version of the eight‐dimensional professionalism attitude questionnaire for student nurses (Instrument of Professional Attitude for Student Nurses).

Methods

In this cross‐sectional study during March to April 2017, after being translated into Persian and receiving experts’ comments face, content, and construct validity of the questionnaire were sought among nursing students. Internal consistency reliability was examined by estimating the Cronbach's alpha coefficient and stability was estimated by calculating intraclass correlation coefficinet.

Results

A total of 750 students with an average age of 24.15 (SD = 1.32) years participated in the study. Both exploratory and confirmatory factor analyses confirmed the construct of the questionnaire. Cronbach's alpha coefficient for the entire instrument was 0.89 and more than 0.70 for all dimensions.

Also the intraclass correlation coefficient for the questionnaire was found to be 0.92, well above acceptable threshold. The findings approved that the Iranian version of Instrument of Professional Attitude for Student Nurses is a reliable and valid questionnaire. Hence, using this questionnaire to conduct studies is recommended.
