Brief Summary

Anxiety problems are a major concern of youth mental health given that the prevalence of anxiety disorders in Dutch children aged up to 12 is approximately 4 to 8 percent. In this group, specific phobias are among the most common. Cognitive Behavioral Therapy (CBT) with exposure as its key ingredient, takes a prominent place in national guidelines for the treatment of anxiety disorders. These guidelines are based on empirical support that exposure is effective in the treatment of specific phobia. Yet, despite the empirical evidence of its efficacy, a gap between theory and practice remains, with exposure-based CBT being underused in clinical practice. For example, a recent Dutch survey found that exposure was mostly practiced outside the formal therapy sessions as homework assignment. It is questionable whether this is effective, given that it might be hard for children to do these assignments independently (e.g., without the help of a therapist or their parents). This study therefore proposes to evaluate the effectiveness of different degrees of therapist and parent involvement during exposure, comparing therapist supported exposure with self-supported exposure with and without the use of parents as co-therapists.

Outcome Measures

Primary Outcomes (1)

  • Change in specific phobia severity (Interference, number of symptoms and general impression of the psychologist)

    Specific phobia severity in children will be measured with a clinical semi-structured interview using the Anxiety Disorder Interview Schedule for Children and Parents (ADIS-IV-C/P). The study will only include the section of specific phobia. Severity of the specific phobia will be rated on a 0-8 interval scale by an independent psychologist on the ADIS-IV (see above). This rating is based on the level of interference, number of symptoms and general impression of the psychologist. A rating 0, 1, 2 or 3 is labelled as no specific phobia, a rating of 4 or 5 is labelled as a mild specific phobia, whereas a rating of 6, 7 or 8 means the specific phobia is labelled as severe. This rating is used to randomize the participants to one of the conditions. The ADIS-IV has good test-retest reliability and concurrent validity.

    At intake (T0), four weeks later at pre-intervention assessment (T1), another four weeks later at post-intervention assessment (T5) and another four weeks later at follow-up assessment (T6)

Secondary Outcomes (3)

  • Change in level of anxiety (Subjective level of fear, Fearful cognitions, Bodily tension, Avoidance and Coping)

    During the first intervention week (T2), the second week (T3), and the third week (T4), and one week later at post-intervention assessment (T5), and four weeks later at follow-up assessment (T6)

  • Change in approach behaviour towards phobic stimulus (Time and distance)

    At pre-intervention assessment (T1), four weeks later at post-intervention assessment (T5) and another four weeks later at follow-up assessment (T6)

  • Change in self-efficacy (Academic, Social and Emotional)

    At pre-intervention assessment (T1), four weeks later at post-intervention assessment (T5) and another four weeks later at follow-up assessment (T6)

Other Outcomes (9)

  • Cost-effectiveness (Healthcare costs and In quality adjusted life years)

    At pre-intervention assessment (T1) and eight weeks later at follow-up assessment (T6)

  • Change in specific phobia diagnosis (Interference, number of symptoms and general impression of the psychologist)

    At intake (T0), four weeks later at pre-intervention assessment (T1), another four weeks later at post-intervention assessment (T5) and another four weeks later at follow-up assessment (T6)

  • Change in comorbid anxiety and depression symptoms

    At pre-intervention assessment (T1), four weeks later at post-intervention assessment (T5) and another four weeks later at follow-up assessment (T6)

  • +6 more other outcomes

Study Arms (3)

Therapist-guided in-session

EXPERIMENTAL

The participants will engage in 2 x 45 minutes of exposure exercises conducted together with the therapist in the mental health care centre. In addition, they will conduct 2 x 45 minutes of exposure exercises by themselves out of session as a homework assignment.

Behavioral: Cognitive Behavioral Therapy

Self-guided out-session

EXPERIMENTAL

The participants will prepare and discuss the exposure exercises together with the therapist in the mental health care centre, and conduct 2 x 2 x 45 minutes of exposure exercises by themselves out of session as a homework assignment.

Behavioral: Cognitive Behavioral Therapy

Parent-guided out-session

EXPERIMENTAL

The participants and one of their parents will prepare and discuss the exposure exercises together with the therapist in the mental health care centre, and conduct 2 x 2 x 45 minutes of exposure exercises together with their parent out of session as a homework assignment.

Behavioral: Cognitive Behavioral Therapy

Interventions

. Each intervention will contain a 60-minute psycho-education session (PE) and two 60-minute exposure sessions (EX), conducted by a mental health professional together with a master student in psychology, who are both weekly supervised by a CBT certified psychologist. In the first (PE) session, participants learn about anxiety, specific phobias and exposure. During this session they will create a fear hierarchy, formulate their cognition about the feared object or situation and determine what they want to achieve during treatment (e.g. goal situation). The next two sessions consist of exposure exercises.
