Psychometric Properties of the Persian Version of the Offspring Cancer Needs Instrument (OCNI)

Abstract

Aim: The offspring cancer needs instrument (OCNI) was developed specifically for assessing unmet psychosocial<br />needs of adolescents and young adults who have a parent with cancer. The aim of this study is to examine the<br />psychometric properties of the Persian version of this instrument. Methods: For this methodological study, translation<br />of OCNI into Persian was conducted using translation and back-translation and revision in line with the developer<br />of the instrument. Then, face and content validity, construct validity, internal consistency and stability of the Persian<br />version of the instrument were examined with a population of 188 adolescents and young people having a parent with<br />cancer in five hospitals in Tehran, Iran. Data were analyzed using SPSS version 16 and LISREL 8.5. Results: The final<br />Persian version of the instrument demonstrated face and content validity proven by expert and participant reviews.<br />Confirmatory factor analysis confirmed construct validity of the instrument and its seven subscales. Cronbach's alpha<br />was 0.96 for the total instrument and 0.76-0.93 for its seven subscales. The intraclass correlation coefficient (ICC)<br />calculated to evaluate the test-retest reliability, was 0.83. Conclusions: The Persian version of OCNI has acceptable<br />psychometric properties. It can be used for measuring psychosocial unmet needs in adolescents and young adults in<br />Persian language populations who have a parent with cancer
