Study summary

The goal of this cluster randomized controlled trial is to evaluate and compare the effects of different testicular self-examination (TSE) training methods on university students' health beliefs and self-examination behaviors regarding testicular cancer (TC) and TSE.

The main questions it aims to answer are:

  • Does receiving brochure-based education or brochure plus audio recordings of TC patient experiences improve students' health beliefs (perceived susceptibility, seriousness, benefits, self-efficacy, and reduced barriers)?
  • Which educational method is more effective in increasing the frequency and performance of testicular self-examination behaviors compared to a control group?

Researchers will compare three groups:

  • Intervention Group 1: Receives an educational brochure on TC and TSE.
  • Intervention Group 2: Receives an educational brochure combined with audio recordings of testicular cancer survivor/patient experiences.
  • Control Group: Receives no specific educational intervention during the study period.

Participants will:

  • Complete baseline questionnaires regarding demographic information, TC/TSE knowledge, health beliefs, and baseline examination practices.
  • Receive the assigned educational material/session according to their randomized cluster.
  • Complete follow-up evaluations at 3 months post-intervention to assess changes in health beliefs, knowledge, and TSE behaviors.

Exclusion criteria

Exclusion Criteria:

  • Previous clinical diagnosis of testicular cancer or any other testicular/scrotal
  • Having undergone major scrotal or testicular surgery (e.g., orchiectomy)
  • Prior formal or professional training on testicular self-examination (TSE) within the last 6 months
  • Inability to complete the educational intervention or follow-up assessments due to sensory or cognitive impairments
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

At the end of the sixth week following the pre-test, the educational brochure group received their respective protocol, followed by post-tests comprising the TSE Behavior Determination Form and the TSE Behavior and Educational Tool Satisfaction Form.

What researchers measure

Primary outcomes

  1. Change in Testicular Self-Examination (TSE) Behavior

    Measured using the TSE Behavior Determination Form to evaluate whether the students perform regular testicular self-examination.

    Time frame: At baseline and at 6 weeks post-intervention

Secondary outcomes

  1. Change in Champion's Health Belief Model Scale Scores

    Evaluated using Champion's Health Belief Model Scale to assess changes in students' health beliefs regarding testicular self-examination between the intervention groups and the control group. Champion's Health Belief Model Scale (CHBMS), consisting of 26 items across five subscales (Perceived Susceptibility, Perceived Severity, Perceived Benefits, Perceived Barriers, and Perceived Self-Efficacy) scored on a 5-point Likert scale (1 to 5). The scale does not yield a total score; each subscale is evaluated separately with varying score ranges depending on the number of items, where higher scores indicate a higher level of each specific health belief.

    Time frame: At baseline and at 6 weeks post-intervention
