When participating in population-based screening for cervical cancer, women experience great anxiety during the weeks of waiting since they learn that they have an altered screening result until the colposcopy is performed. In this study we want to verify how anxiety decreases when the information is improved and an audiovisual support is added when giving it.

This study is designed as a double-blind clinical trial. Candidate patients for this study are women referred to a colposcopy consultation after an altered result of the screening test. Those women who have previously been in the colposcopy consultation or have had this test performed in a private center are excluded.

The initial recruitment is done by telephone. If they accept, they are given an appointment at the hospital one day where, after being informed again and signing the informed consent, they are randomized and assigned a group. There are 2 groups, in one they receive an envelope with the information in writing that was created in Osakidetza and is available on the website of said organization, and the other group receives a sheet with the links to the videos created for this study in the same envelope. In this way, both groups assume that they are receiving information and we avoid bias. The principal investigator is the one who carries out this phase and distributes the envelopes, but is unaware of their contents. Previously, a collaborator fills in the envelopes according to the randomization code and indicates outside the envelope the order in which they should be delivered. Only she knows the randomization code and she will not reveal it until the end of the study.

To analyze the level of anxiety, the participants will fill out 2 scales before receiving the information, and they will return them on the day of the colposcopy before performing it. The scales used are the Spielberger´s State-trait anxiety inventory (STAI) and the Cohen´s PerceivedStress Scale 14 (PSS14). The STAI scale has 40 items, scored from 0 (never) to 3 (very much) points. The final result can range between 0 and 60, higher scores are related to a higher level of anxiety. The PSS14 scale consists of 14 items with a five-point scale response format (0 is never and 4 is very often). The scale scores from 0 to 56; higher scores indicate higher perceived stress.

It will also be analyzed whether the waiting time until the colposcopy and the level of academic studies influence the level of anxiety. And the perception of the colposcopy will be analyzed, with the VAS scale, according to their level of anxiety and the way they received the information.

Inclusion Criteria:

• Patients who participate in the Osakidetza cervical cancer screening program and are referred to the colposcopy consultation of the Hospital Universitario Donostia due to an altered screening test.

Exclusion Criteria:

• Patients who have previously been in the colposcopy consultation or have gone to a private center to receive information about their altered result or to undergo colposcopy.

This clinical trial is aimed at all people with a cervix, regardless of the gender that represents them. Although the vast majority are women, men with a cervix can participate.

The randomization code is only known to a collaborator who fills the envelopes according to said code. The envelopes are distributed in order of arrival at the study, the researcher in charge of distributing them and recording the information does not know the randomization code. At the end of the study and registering all the data, the collaborator who has the code will deliver it to the principal investigator of the study.

In all the envelopes there is some type of information so that the patients are also blind. The experimental group is given a sheet with the links to the videos and the other group is given written information, which is available on the health organization's website. In this way, no group feels that it does not receive information and we control said bias.
