Behavioral: Short-Term Psychodynamic Group Therapy
Participants assigned to this arm did not receive the psychodynamic group therapy intervention during the study period.
The intervention consisted of 16 online psychodynamic group therapy sessions, each lasting approximately 90 minutes. Sessions were conducted in a group format via Google Meet. The intervention focused on psychodynamic exploration of problematic pornography use, including associated emotions, interpersonal patterns, internal conflicts, and difficulties in emotion regulation.
Pornography Craving Questionnaire (PCQ) Score
Pornography craving was assessed using the Pornography Craving Questionnaire (PCQ). Higher scores indicate greater pornography craving.
Time frame: Baseline, Week 8, and 3-month follow-up
Difficulties in Emotion Regulation Scale-16 (DERS-16) Score
The Difficulties in Emotion Regulation Scale-16 (DERS-16) was used to assess difficulties in emotion regulation. The scale consists of 16 items rated from 1 to 5, yielding a total score ranging from 16 to 80. Higher scores indicate greater difficulties in emotion regulation and therefore a worse outcome.
Time frame: Baseline, Week 8, and 3-month follow-up
Trait Shame and Guilt Scale - Shame Subscale Score
Shame was assessed using the shame subscale of the Trait Shame and Guilt Scale (TSGS). The mean subscale score ranges from 1 to 5, with higher scores indicating greater levels of shame and therefore a worse outcome.
Time frame: Baseline, Week 8, and 3-month follow-up
Plan to share: No — Individual participant data will not be publicly shared due to the sensitive nature of the data and participant confidentiality considerations.
