5-week ACT Group Intervention based on the Self-Help Booklet by the World Health Organization "Doing What Matters in Times of Stress: An Illustrated Guide".

Waiting-list

A 90-120 minute 5-week group intervention for unaccompanied minors. Each week there will be a different focus. Week 1: Grounding, Week 2: Unhooking, Week 3: Values, Week 4: Self-compassion, Week 5: Making room for unwanted thoughts and feelings.

This is a 27-item instrument that consists of five dimensions of quality of life: physical well-being (5 items), psychological well-being (7 items), autonomy and relationship with parents (7 items), peers and social support (4 items), and school environment (4 items). The questions concern the last seven days and answers are given on a five-point Likert scale ('Not at all, slightly, moderately, very, extremely' or 'never, seldom, quite often, very often, always'). Higher scores on the KIDSCREEN-27 reflect higher quality of life and wellbeing. Internal consistency of this scale was considered satisfactory (Cronbach's alpha= >.70).

This scale includes 21 items and will be used to assess for symptoms of depression, anxiety and stress in our sample. The Depression scale assesses hopelessness, low self-esteem, and low positive affect. The Anxiety scale assesses autonomic arousal, physiological hyperarousal, and the subjective feeling of fear. The Stress scale items assess tension, agitation, and negative affect. There are seven items per scale and participants must rate their past week on a Likert-type scale (0-3). Higher scores indicate higher levels of depression, stress and anxiety. Cronbach's alphas indicating high internal consistency for Depression .94, Anxiety .84 and Stress .91.

This scale will be used to assess for any post-traumatic stress symptoms. The total number of items in the scale are 8 items. Four of the items assess intrusion (intrusive thoughts, feelings) and the remaining four items assess avoidance (avoidance of situations, feelings). The items are scored on a 4- point scale, where higher scores indicate higher levels of intrusion or avoidance. The CRIES-13 (Smith, Perrin, Dyregov, & Yule, 2003) was found to have high internal consistency (Cronbach's alpha= 0.80). Sensitivity (i.e., the probability that someone with a diagnosis of PTSD will screen positive) was found to be .94-1.0. Specificity (i.e., the probability that someone without a diagnosis of PTSD will screen negative) was found to be .59-.71. The overall efficiency rate of the CRIES-8 is 75-82.7%.

This is an 8-item self-report questionnaire which assesses the process of psychological flexibility. Each item is rated on a five-point scale from 1 (very often) to 5 (very rarely).

This questionnaire consists of 25 items which capture four key areas within ACT: Therapist Stance (7 items), Open Response Style (6 items), Aware Response Style (6 items) and Engaged Response Style (6 items). Within each area there are items to score the therapist's behaviour as ACT consistent and ACT inconsistent. Scoring is rated on a 4-point scale from 0-3 (0= 'This behaviour never occurred', 1= 'Therapist rarely enacts this behaviour', 2= 'Therapist sometimes enacts this behaviour', 3= 'Therapist consistently enacts this behaviour'). Within 'Engaged response style' for instance, "Therapist gives the client opportunities to clarify their own values" would be considered ACT consistent, "Therapist imposes their own, other's or society's values upon the client" would be considered ACT inconsistent. A total score can be calculated for each subscale as well as a total ACT consistent score and total ACT inconsistent score. Inter-rater reliability was deemed moderate to excellent.
