      Adults with high anxiety sensitivity (AS) and a mental health diagnosis of anxiety,&#xD;
      depression, or posttraumatic stress will be recruited and will be randomly assigned to either&#xD;
      transdiagnostic cognitive behavioural therapy (CBT) for AS or disorder-specific CBT for their&#xD;
      primary mental health problem. The study outcomes - AS, anxiety, mood, and substance use&#xD;
      symptoms, and functional impairment - will be assessed at pre-and post-treatment and 6 and 12&#xD;
      months post-treatment via standardized self-report measures completed by participants and a&#xD;
      standardized diagnostic interview.&#xD;

  <detailed_description>
    <textblock>
      While our previous work has provided some evidence that cognitive behavioural therapy (CBT)&#xD;
      for anxiety sensitivity(AS) reduces mental health symptoms, the current study aims to&#xD;
      determine whether this treatment works as well as traditional disorder-specific CBT (which&#xD;
      aims to treat the specific disorder a person presents with, such as CBT for panic disorder&#xD;
      for someone with panic disorder) in treating anxiety and depression. This will be the first&#xD;
      study to have looked at this question.&#xD;
&#xD;
      Our objectives are to determine:&#xD;
&#xD;
        1. if there is a difference in the extent to which CBT for AS vs. disorder-specific CBT&#xD;
           reduces, in the short- and long-term, a) AS, b) symptoms of a person's primary and&#xD;
           secondary mental health problems, and c) functional disability (i.e., a person's ability&#xD;
           to function in day-to-day life);&#xD;
&#xD;
        2. if the two treatments lead to differences in the number of participants who no longer&#xD;
           meet the requirements for a diagnosis (of their primary or secondary mental health&#xD;
           problems) in the short- and long-term; and&#xD;
&#xD;
        3. if the treatments are seen as similarly satisfactory by participants.&#xD;
&#xD;
      Eligible participants will be randomly assigned (via online random number generator) to&#xD;
      either transdiagnostic CBT for AS or disorder-specific CBT for their primary mental health&#xD;
      problem. Both CBT interventions are evidence-based, guided by treatment manuals/workbooks&#xD;
      (provided to participants), and involve 12 weekly therapy sessions. The AS intervention will&#xD;
      also involve a physical exercise component (i.e., running/brisk walking 3x/week starting on&#xD;
      week 5) and participants will be provided with a wearable fitness device designed to provide&#xD;
      physiological indices of arousal and track physical activity. The study outcomes - AS,&#xD;
      anxiety, mood, and substance use symptoms, and functional impairment - will be assessed at&#xD;
      pre-and post-treatment and 6 and 12 months post-treatment via standardized self-report&#xD;
      measures completed by participants and a standardized diagnostic interview.&#xD;

    <description>The ASI-3 is an 18-item self-report measure that indexes the amount of fear an individual experiences with respect to anxiety-related body sensations. Participants indicate the extent to which they agree or disagree with each item (e.g., &quot;It scares me when my heart beats rapidly&quot;) on a 5-point Likert-type scale.</description>

    <description>Administered by a trained researcher blind to treatment condition. The SCID-5 has been widely used in numerous research studies and is well empirically validated.

    <description>The Depression Anxiety Stress Scales - 21. The DASS-21 is a shortened version of the 42-item DASS and is composed of three subscales: Depression, Anxiety, and Stress. Individuals indicate the extent to which a particular negative emotional state (e.g., &quot;I found it difficult to relax&quot;) has applied to them over the past week on a 4-point Likert-type scale (0 = Did not apply to me at all to 3 = Applied to me very much or most of the time).</description>

    <time_frame>baseline (i.e., start of study), 12 weeks, 6 months, and 12 months follow-up</time_frame>
    <description>Clinical Outcomes in Routine Evaluation (CORE-10) is a brief, 10-item self-report measure designed to assess common presentations of symptoms of psychological distress. Participants are asked to indicate how often in the past week they have felt a series of symptoms (e.g., &quot;I have felt tense, anxious, or nervous&quot;) on a 5-point Likert-type scale.</description>

    <description>The Sheehan Disability Scale will be used to measure functional impairment in three domains: work/school, family life, and social. Using a 10-point visual analogue scale, participants rate the extent to which their general mental health symptoms disrupt their work/school, family life/responsibilities, and social life. Participants also indicate the number of days their mental health symptoms caused them to miss school/work as well as the number of days their symptoms had caused their performance to be reduced during the past week. The SDS is well-validated and widely used with a range of populations.</description>

    <description>Despite being designed as a screening tool, the AUDIT is commonly used to assess alcohol use problems pre- and post-treatment. The AUDIT is a 10-item self-report measure that asks participants to report on their frequency of alcohol use, binge drinking, and alcohol-dependent behaviours. Responses are scored on 5-point Likert-type scales. Finally, participants report if they have experienced problems caused by alcohol use on a 3-point Likert-type scale.</description>
