Sponsored by Centre Hospitalier Esquirol · Observational
This is a prospective observational psychology study on a non-clinical population, involving the use of questionnaires (non-interventional research).
This study involves the collection of data associated with High Intellectual Potential characteristics, sensory profile, and includes clinical measures such as anxiety anxiety, autistic traits and coping in High Intellectual Potential and control participants.
7,201 studies on the registry are indexed under Anxiety Disorders; 1,682 are open to participants now.
This study's planned enrollment of 160 is close to the median of 168 across 977 observational studies indexed under Anxiety Disorders.

This observational study consists of data collection using a structured questionnaire based on an e-CRF, distributed by e-mail. Four questionnaires were administered : the Revised Ritvo Autism and Asperger Diagnostic Scale (RAADS-R-Fr), the Adolescent/Adult Sensory Profile (AASP), the Coping Inventory for Stressful Situations (CISS) and the State-Trait Anxiety Inventory (STAI-Y). Socio-demographic and treatments were collected.
For participants with High Intellectual Potential, the total Intelligence Quotient (IQ) or General Ability Index (GAI), along with the index scores from the Wechsler scales (Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, and Processing Speed Index), will be extracted from the cognitive assessment previously completed by the participant prior to study enrollment.
Sensory profile from the Adolescent and Adult Sensory Profile according to each group.
Sensory profile scores is obtained using the self-report questionnaire Adolescent and Adult Sensory Profile (AASP) after the participant has been included in the study. Subscores for sensory sensitivity, low registration, sensation seeking, and sensation avoidance are collected. For each subscore, the minimum and maximum values range from 15 to 75. A high score indicates high sensory sensitivity.
Time frame: At enrollment
Sensory profile from the Adolescent and Adult Sensory Profile according to the cognitive profile of the High Intellectual Potential group.
Sensory profile scores will be obtained using the Adolescent and Adult Sensory Profile (AASP) scale during an individual interview after the participant has been included in the study. Subscores for sensory sensitivity, low registration, sensation seeking, and sensation avoidance will be collected. For each subscore, the minimum and maximum values range from 15 to 75. A high score indicates high sensory sensitivity.
Time frame: At enrollment
Scores for anxiety from the State and Trait Anxiety Inventory according to each group
Anxiety scores will be obtained using the State and Trait Anxiety Inventory (STAI-Y) scale during an individual interview after the participant has been included in the study. Subscores for State Anxiety and Trait Anxiety will be collected. For each subscore, the minimum and maximum values range from 20 to 80. A high score indicates high anxiety
Time frame: At enrollment
Scores for task coping drawn from the Coping Inventory for Stressful Situations according to each group
Coping scores will be obtained using the Coping Inventory for Stressful Situations (CISS) scale during an individual interview after the participant has been included in the study. The task-oriented coping subscore, emotion subscore, avoidance subscore, distraction subscore, and social diversion subscore will be collected. The minimum and maximum values range from 16 to 90. A high score indicates high oriented coping.
Time frame: At enrollment
Description of the frequency of autistic traits for each group
The frequency of autistic traits will be obtained using the Revised Ritvo Autism and Asperger Diagnostic Scale (RAADS-R-Fr) during an individual interview after the participant has been included in the study. The minimum and maximum values range from 0 to 240. The generally accepted threshold for significant autistic traits is 70. A high score indicate high autistic traits.

Started Apr 2025 (actual). Primary completion is estimated for Apr 2027, 24 months after the start.
Of 411 non-industry observational studies under Anxiety Disorders, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 49. This study's planned 24 months is above that.
Counting every sponsor, half of 439 studies reached it within 19 months; a quarter within 6 and three quarters within 48.
