A Multiple Baseline Feasibility Trial of Social Management Training for People With Sex Chromosome Aneuploidies (TRICXY-SMT)

July 14, 2026 updated by: Krister W Fjermestad, University of Oslo
We will examine is Social Management Training, a 10-session group-based psychosocial intervention will improve the primary outcome mental health, and secondary outcomes executive functions and autism symptoms, in a multiple baseline design with 3 pre-measurement points and 3 post-measurement points spanning 30 weeks, including the 10 weeks of intervention. Participants will be adults (16-65 years) with sex chromosome aneuploidies.

Detailed Description

Background: Persons with sex chromosome aneuploidies (SCAs, i.e., a number of sex chromosomes that is different from the most common 46,XX and 46,XY), often struggle with social interactions. A Dutch pilot study examined Social Management Training (SMT), an intervention designed to help people develop their abilities to navigate interactions with others in men with Klinefelter syndrome (KS; 47,XXY). SMT was adapted to target executive functions, emotion regulation, and social cognition in a novel neurocognitive-behavioral program tailored to the specific vulnerabilities of men with KS, and showed promising outcomes. The current study aims to expand on the Dutch pilot study by (1) Adapting SMT to Norwegian individuals with SCAs in an online-delivered format enabling wide geographic reach; (2) Testing the feasibility, acceptability, and potential benefits of SMT; and (3) Examine the use of SMT on SCAs beyond KS. Methods: The intervention comprises 10 group sessions. Through a single-group multiple baseline design, measures are collected at six time points; three pre- and three post-intervention. The main effect to be examined is the difference between pre- and post-intervention. The primary outcome is mental health, and the secondary outcomes are social and executive functioning. Participants are recruited through the Norwegian National Center for Rare Diseases, the Norwegian Klinefelter association, and endocrinologists. We plan to include 20-30 participants by the end of 2028. Discussion: SMT aims to evaluate the feasibility of a digitally based psychosocial intervention designed to improve mental health, as well as social, emotional and executive functioning among individuals with SCAs. The findings will inform intervention refinement and the design of a future definitive randomized controlled trial. The development of such interventions can lead to socio-economic benefits in the form of long-term improved health outcomes for people by improving overall functioning.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
30

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

The inclusion criteria are: (a) Proficiency in a Scandinavian language. Participants must state that they have satisfactory skills to participate in group discussions, and answer questionnaires in Norwegian; (b) Age 16 to 69 years. The age range is set to include adults of the age of consent for participation in health research. The upper age limit was set to prevent measurements from being affected by age-related factors; (c) Access to a computer (or smartphone) with internet connection - but note that we can lend a computer to participants who may require this; (d) Genetically confirmed SCA. Participants provide medical confirmation of diagnosis, unless participants are recruited via Frambu (where medical confirmation is available in the user registry for KS 47,XXY karyotype; Jacobs 47,XYY karyotype; Triple X, 47,XXX karyotype; and Turner 45,X karyotype).

There are no explicit exclusion criteria. Ongoing assessments are made during eligibility screening and when conducting training program regarding appropriateness of the training program, both individually and in groups. If the group leader becomes aware of information that indicates the need for specialist health services (e.g., indication of severe mental illness or acute suicidality), this is handled on a case-by-case basis, and the person concerned is then put in contact with the appropriate health care services.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Symptom Checklist 25 (SCL-25)
Time Frame: Measured three times during 8 weeks prior to the intervention and then three times during 8 weeks after the intervention
The SCL-25 is a 25 item measure of mental health that compiles into an anxiety and a depression dimension (compared to nine dimensions in the full 90-item version).
Measured three times during 8 weeks prior to the intervention and then three times during 8 weeks after the intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The Social Responsiveness Scale - Second edition (SRS-2).
