About this study

Official title: How do You Feelee? Does an Ordinary Question a Day Supports Youth in a Forensic Outpatient Setting to Become More Emotional Balanced? A Multiple Case Experimental Design

This intervention study aims to explore the addition of the Feelee app (using active emoji data with passive behavioral data through phone sensing) in treatment as usual for adolescents in the forensic outpatient setting.

Participants will use Feelee for 4 weeks, which means specifying an emoji each day and collecting the passive data on the background. The collected active and passive data will be discussed through the clinicians during the participants' weekly treatment sessions.

Read the detailed description

Participants will be subjected to a ABA baseline design: including a 2-weeks baseline phase (A), 4-weeks intervention phase (B) and 2-weeks follow-up phase.

During the baseline phase (A), participants will fill in a daily questionnaire that measures different aspects of their emotion regulation skills. The use of the Feelee app is not allowed yet. After 2-weeks, the intervention phase starts, meaning participants will use the Feelee app every day during a 4-weeks period. The use of the Feelee app includes specifying an emoji and collecting the passive data on the background. Furthermore, the collected active and passive data will be discussed through the clinicians during the participants weekly treatment sessions. Participants will also be continuing to complete the daily questionnaire. After 4-weeks, the follow-up phase starts. Participants need to remove the Feelee app and will follow their treatment as usual. However, participants still need to complete the daily questionnaire. After 2-weeks the follow-up phase and main study part has ended.

Throughout the ABA baseline, pre-measurement (T0), post-measurement (T1) follow-up measurement (Tf1) will be conducted before and after the intervention and during follow-up. Last, a 3-months follow-up will be conducted to identify possible long-term effects.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Feelee appDevice

    Adolescents uses the Feelee app for 4-weeks in addition to treatment as usual in the forensic outpatient setting. The use of Feelee involves: submitting one emoji every day and allow the Feelee app to read the following passive data from the health app on the smartphone: number of steps and number of hours of sleep. The collected Feelee data will be presented in a dashboard in the Feelee app itself which will be discussed by the clinician in the weekly treatment session (in case the adolescents agreed to show the Feelee data to the clinician).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Emotion regulation: measured by a composite of items from the Difficulties in Emotional Dysregulation Scale (DERS-36) and Regulation of Emotion Systems Survey for daily usage (RESS-EMA)

    Emotion regulation involves the ability to recognize, comprehends and manage emotions.

    The first 2 items are from the DERS-36 scale and measure construct recognize (clarity) and manage (impulse) of emotion regulation. Answers on these scales can be given on a 5-point Likert-scale (0= almost never too 5= almost always).

    The other 4 items are from the RESS-EMA survey The RESS-EMA questionnaire consists of different aspects of the emotion regulation systems and strategies that are suitable for daily usage. The items included in the daily questionnaire are: comprehends (rumination), comprehends (reappraisal), manage (distraction) and manage (suppression). Answers can be given from 0 = not at all to 10 = very much.

    Measured: Daily questionnaire (24 hour interval). From Day 0 (Week 1) up to Day 56 (Week 8).

Secondary outcomes (3)
  1. Emotional differentiation: Positive and Negative Affect Schedule (PANAS)

    Emotional differentiation includes the ability to recognize and distinct different emotional expressions.

    Participants will be asked to rate the extent they experienced one of the 20 items that describes different emotions. The instruments consist of 2 subscales: positive affect and negative affect. These concepts will be scored on a 5-point Likert scale, using the following options: 1 = 'Very slightly/not at all', 2 = 'A little', 3 = 'Moderately', 4 = 'Quite a bit' and 5 = 'Extremely'.

    Measured: Pre-measurement (T0) at Week 1, post-measurement (T1) at Week 6 and follow-up-measurement at Week 8

  2. Self-reflection: Self-Reflection and Insight Scale for Youth (SRIS-Y)

    Self-reflection involves the process of looking back at experiences, emotions and behavior in order help individuals to clarify a meaning to it and gain more self-awareness.

    The SRIS-Y is a 17-item self-report questionnaire, answered with a 6-point Likert scale ranging from 1 = 'disagree strongly' to 6= 'agree strongly'. The instrument consists of two subscales self-reflection and and insight resulting in two separate scores. A higher score represents a higher degree of self-reflection and self-insight.

    Measured: Pre-measurement (T0) at Week 1, post-measurement (T1) at Week 6 and follow-up-measurement at Week 8.

  3. Emotional awareness: Emotional awareness subscale of the Multidimensional Assessment of Interoceptive Awareness (MAIA)

    Emotional awareness involves a subjective understanding of the emotional states and ability to recognize possible causes underlying the emotional states.

    In this study, only the emotional awareness subscale of the MAIA will be used. Answers can be given on a 6-point Likert scale ranging from 0 = 'never' to 5 = 'always'. Scores of the subscale can easily been calculating the total score and dividing it by the number of items belonging to the subscale. A higher score represents a higher degree of emotional awareness.

    Measured: Pre-measurement (T0) at Week 1, post-measurement (T1) at Week 6 and follow-up-measurement at Week 8.
