Validity and reliability analysis of the planned behaviour theory scale related to the testicular self-examination in a Turkish context

OBJECTIVE - This study aimed to determine the validity and reliability levels of the Planned Behaviour Theory Scale as related to a testicular self-examination.

METHODS - The study was carried out in a health-profession higher-education school in Ankara, Turkey, from April to June 2012.

The study participants comprised 215 male students. Study data were collected by using a questionnaire, a planned behaviour theory scale related to testicular self-examination, and Champion's Health Belief Model Scale (CHBMS).

RESULTS - The sub-dimensions of the planned behaviour theory scale, namely those of intention, attitude, subjective norms and self-efficacy, were found to have Cronbach's alpha values of between 0.81 and 0.89. Exploratory factor analysis showed that items of the scale had five factors that accounted for 75% of the variance. Of these, the sub-dimension of intention was found to have the highest level of contribution. A significant correlation was found between the sub-dimensions of the testicular self-examination planned behaviour theory scale and those of CHBMS (p < 0.05).

CONCLUSIONS - The findings suggest that the Turkish version of the testicular self-examination Planned Behaviour Theory Scale is a valid and reliable measurement for Turkish society.
