E-Mergir: A Digital Psychosexual Intervention for the Promotion of Mental and Sexual Health of Prostate Cancer Survivors (E-Mergir)

4 augustus 2026 bijgewerkt door: Ana Luísa de Matos Dias Quinta Gomes, Universidade do Porto

E-Mergir: a Randomized Controlled Trial to Test the Efficacy of a Digital Psychosexual Intervention for the Promotion of Mental and Sexual Health of Prostate Cancer Survivors

Prostate cancer (PCa) survivors frequently experience enduring psychosexual challenges following treatment, including sexual dysfunction, emotional distress, and reduced quality of life. Despite these difficulties, access to tailored support remains limited, highlighting the need for scalable and accessible alternatives such as digital interventions. This study presents the protocol for a randomized controlled trial (RCT) evaluating the effectiveness of E-Mergir, a digital psychosexual intervention developed for PCa survivors. Grounded in cognitive behavioral therapy (CBT) and mindfulness strategies, the intervention aims to enhance both sexual and mental well-being. The trial employs a wait-list control design with randomized allocation. Participants will complete assessments at baseline, post-intervention, and follow-up, using validated measures related to sexual outcomes (sexual satisfaction, pleasure, function, distress, and beliefs) and mental health outcomes (quality of life, anxiety, depression, mindfulness, relationship satisfaction, and automatic thoughts). The study aims to determine whether E-Mergir is an effective digital intervention for improving psychosexual outcomes in PCa survivors, compared to a wait-list control group. It also aims to examine treatment predictors to illustrate the mechanisms through which improvements in mental and sexual health are achieved. If effective, E-Mergir could address a critical gap in supportive care for PCa survivors and serve as a model for culturally tailored digital psychosexual interventions globally.

Gedetailleerde beschrijving

This study was approved by the Ethical Board of Coimbra University Hospital. An online psychological intervention (e-Health app technology) specifically tailored to meet the needs of Portuguese men with prostate cancer was developed to promote participants' mental and sexual health. The intervention protocol was designed under Cognitive-Behavior Therapy (CBT) principles, featuring psychological and sexual health promotion strategies. The intervention program consists of 5 modules covering components of psychoeducation, sexual rehabilitation, mindfulness, cognitive restructuring, and relapse prevention. The modules will be delivered online (using text, videos, and graphics) along with therapeutic guidance and support provided by a certified Clinical Psychologist over eight weeks.

Participants will be recruited through medical doctors at the Urology department of Coimbra University Hospital and invited telephonically to participate in the present study. If the potential participant declares interest, a researcher will contact them telephonically to confirm the following inclusion criteria: i) bein a prostate cancer survivor; ii) 18 years old or older; iii) have the ability to give informed consent; iv) own a smartphone and have internet access; v) no other oncological diagnoses over the past five years, vi)no severe neurological or psychological disorders.

Participants will be randomly assigned to one of two conditions: 1) e-Health psychological intervention (n=53); 2) waiting list group, (n= 53). Participants will be clinically assessed before and after the intervention on different psychosexual dimensions (e.g., mental health, quality of life, sexual dysfunction). The experimental group is expected to improve regarding mental and sexual well-being outcomes compared to the control group. Furthermore, the experimental group is expected to show the program's acceptability. This study aims to inform a future a randomized control trial that aims to further test the e-Health intervention's efficacy. Pre, mid-term, (at 4 weeks) post-test, three-month and six-month follow-up assessments will be performed for both groups.

Primary outcomes: psychological distress, sexual distress, sexual satisfaction, sexual pleasure, mindfulness, and quality of life.

Secondary outcomes: Sexual function, relational satisfaction, sexual dysfunctional beliefs, and automatic thoughts.

Exploratory outcomes: post-traumatic growth All scales are validated and adapted to the Portuguese population. Furthermore, a semi-structured interview will be conducted with experimental group participants by the end of the study to collect further insight on how possible mental and sexual improvements were achieved.

Participants' data will be stored in an encrypted file, saved on a computer, and only accessible to the main researchers of this study. Confidentiality will be guaranteed by assigning an individual code to each participant. This code will be used to log into the digital intervention and complete psychometric scales. Interviews will be recorded and transcribed. Transcriptions will be marked with the same code to ensure the association of the collected data.

Statistical procedures will be performed using IBM SPSS and include i) descriptive analyses; ii) MANOVA to measure differences among groups and to compare assessment moments; iii) Multiple Regression Analysis to examine treatment predictors; iv) Structural Equation Modeling to illustrate the mechanisms by which improvement of mental and sexual health was achieved.

Experimenteel: Experimental: testing the digital intervention
Experimental: testing the digital intervention. Prostate cancer survivors (n=53) randomly assigned to this arm will complete a digital psychosexual intervention and will be accompanied weekly by a certified clinical psychologist to monitor progress (synchronous or asynchronous). Pre- midterm (4 weeks into intervention) and post testing involve questionnaires collecting data on psychosexual variables. At post-testing a 30-minute interview will be conducted to collect information on how possible mental and sexual health improvements were achieved.

Geen tussenkomst: Waiting list group: waiting to access the intervention after an eight-week waiting period.
Waiting list group: waiting to access the intervention after an eight-week waiting period. Prostate cancer survivors (n=53) randomly assigned to this arm will not be accompanied or get access to the intervention during the eight week period in which the experimental group is completing the intervention. Pre- midterm and post testing involve questionnaires collecting data on psychosexual variables. After post testing the waiting-list arm will gain access to the intervention.
