NCT06404684

Brief Summary

The goal of this randomized study is to learn if a psychological intervention can treat help-seeking patients with paraphilic disorders. The main questions it aims to answer are:

  1. 1.Is psychological therapy helpful for the reduction of problematic sexual behaviors among patients with paraphilic disorders?
  2. 2.Is psychological helpful for the reduction of psychiatric symptoms and risk factors for sexual violence and improving quality of life among patients with paraphilic disorders?
  3. 3.How do patients with paraphilic disorders describe pathways to care (e.g. perceived obstacles to seeking care) and how do they experience the treatment?

Outcome Measures

Primary Outcomes (6)

  • Questions about sexual behaviors ("diary")

    Three questions about time spent on problematic sexual behaviors or fantasies, level of desire and sex as coping. Each question is scored 0-4. The main outcome measure is the total score of these three questions (0-12 points). A higher score indicates more severe problems.

    From date of randomization until the date of end of treatment (week 12), and a follow-up assessement 3 months after end of treatment.

  • Questions about sexual behaviors ("diary")

    Three questions about time spent on problematic sexual behaviors or fantasies, level of desire and sex as coping. Each question is scored 0-4. The three problem areas described under main outcome are handled as separate items and analyzed separately. A higher score indicates more severe problems.

    From date of randomization until the date of end of treatment (week 12), and a follow-up assessement 3 months after end of treatment.

  • Frotteuristic Disorder:Current Assessment Scale (FD: CAS)

    The questionnaire will be used if the participant has a diagnosis of frotteuristic disorder. The questionnaire assesses frotteuristic behaviors. The questionnaire is scored 0-32. A higher score indicates more severe problems.

    start of randomization (phase A), start of treatment (phase B), in the middle of treatment (week 6), at end of treatment (week 12), and follow-up 3 months after treatment.

  • Voyeuristic Disorder: Current Assessment Scale (VD: CAS)

    The questionnaire will be used if the participant has a diagnosis of voyeuristic disorder. The questionnaire assesses voyeuristic behaviors. The questionnaire is scored 0-32. A higher score indicates more severe problems.

  • Exhibitionistic Disorder: Current Assessment Scale (ED: CAS),

    The questionnaire will be used if the participant has a diagnosis of exhibitionistic disorder. The questionnaire assesses exhibitionistic behaviors. The questionnaire is scored 0-32. A higher score indicates more severe problems.

    start of randomization (phase A), start of treatment (phase B), in the middle of treatment (week 6), at end of treatment (week 12), and follow-up 3 months after treatment.

  • Coercive Sexual Sadism Disorder: Current Assessment Scale (CSSD: CAS)

    The questionnaire will be used if the participant has a diagnosis of Coercive Sexual Sadism Disorder. The questionnaire assesses coercive and sadistic (sexual) behaviors. The questionnaire is scored 0-32. A higher score indicates more severe problems.

    start of randomization (phase A), start of treatment (phase B), in the middle of treatment (week 6), at end of treatment (week 12), and follow-up 3 months after treatment.

Secondary Outcomes (11)

  • A question about general well-being

    From date of randomization until the date of end of treatment (week 12), and a follow-up assessement 3 months after end of treatment.

  • Hospital Anxiety and Depression Scale (HADS)

    start of randomization (phase A), start of treatment (phase B), in the middle of treatment (week 6), at end of treatment (week 12), and follow-up 3 months after treatment.

  • The Brief version of the Difficulties in emotional regulation scale (DERS-16)

    start of randomization (phase A), start of treatment (phase B), in the middle of treatment (week 6), at end of treatment (week 12), and follow-up 3 months after treatment.

  • Brunnsviken Brief Quality of Life Inventory (BBQ)

    start of randomization (phase A), start of treatment (phase B), in the middle of treatment (week 6), at end of treatment (week 12), and follow-up 3 months after treatment.

  • Perceived Social Support (PSS-14)

    start of randomization (phase A), start of treatment (phase B), in the middle of treatment (week 6), at end of treatment (week 12), and follow-up 3 months after treatment.

Other Outcomes (2)

  • Qualitative interview (research question c)

    After completion of treatment (week 12)

  • Quality assurance of the manual after each module

    After each treatment module (i.e., 10 times under a time-period of 12 weeks)

Study Arms (1)

Cognitive behavioral therapy (CBT)

EXPERIMENTAL

The current CBT-manual is based on the CBT-manual used for hypersexual disorder, which was developed by ANOVA and evaluated scientifically, (Hallberg 2017, 2019, 2020), but has now been adapted to better meet the current target group. The CBT manual addresses specific sexual problematic behaviors but also contains interventions to deal with comorbidity (e.g. depression and anxiety). The treatment consists of 10 modules and is given by a psychologist (face to face or video).

Behavioral: Cognitive behavioral therapy (CBT)

Intervention Model
SINGLE GROUP
Model Details: we will use a multiple baseline single-case experimental design (SCED) with phase A (baseline) and phase B (treatment). Participants are randomized to different lengths of phase A; 15-21 days, so-called open randomization. Phase B is the CBT treatment. The B phase aims to last 84 days (12 weeks). Seven participants will be included with the main diagnosis of voyeurism, exhibitionism and/or frotteurism, and seven participants with coercive-sexual sadism disorder. The participants in each group will be randomized to seven lengths of phase A. These two groups of seven participants will be treated and analyzed separately.
