About this study
Official title: Just ACT: School-Based Program Using Acceptance and Commitment Therapy (ACT) to Promote Student Well-being
Most psychological conditions start developing during adolescent years. This makes adolescence an ideal and critical window for prevention efforts that help enhance stress management and mental health among the younger generations. This pilot study aims to develop a brief prevention program that focuses on youths' well-being and living as guided by their personal values.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Acceptance and Commitment TherapyBehavioural
Also called ACT
The current program is based on ACT and consists of four one-hour sessions covering the six core components of psychological flexibility. The four sessions respectively focus on Cognitive Defusion, Being Present and Acceptance, Self-as-Context and Values, and Committed Action. All sessions involve experiential learning activities and reflective discussions. Each participant also receives a workbook to facilitate post-session home practice.
| Study group | Role | What they receive |
|---|---|---|
| Treatment | Experimental | Group-based Acceptance and Commitment Therapy for youth delivered across four one-hour sessions Receives: Behavioral: Acceptance and Commitment Therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Attendance
Attendance across four sessions in percentage
Measured: At the end of treatment
Change in psychological flexibility as measured with the Multidimensional Psychological Flexibility Inventory
The Multidimensional Psychological Flexibility Inventory (MPFI; Rolffs et al., 2018) is the only validated measure that provides separate ratings on the six core processes of ACT (see Barrett et al., 2019). Items are rated on a 6-point Likert scale, from 1 - Never True to 6 - Always True, and averaged to obtain a score for each of the dimensions.
Measured: Before treatment, between the second and third session, within one week after treatment, and one month after treatment
Secondary outcomes (5)
Treatment retention
Percentage of participants staying in treatment through the end
Measured: At the end of treatment
Change in well-being as measured with the Flourishing Scale
The Flourishing Scale (FS) is an 8-item rating scale that measures sociopsychological prosperity, in terms of social relationships, purposeful or meaningful living, self-respect, and feeling of competence. Items are rated on a 7-point Likert scale, from 1 - Strong Disagreement to 7 - Strong Agreement.
Measured: Before treatment, within a week after treatment, and one month after treatment
Change in depressive symptoms as measured with Patient Health Questionnaire (PHQ-9)
The nine-item Patient Health Questionnaire (PHQ-9; Kroenke \& Spitzer, 2002) is a gold-standard measure of depressive symptoms an individual experienced in the prior two-week period. Items are rated on a 4-point Likert scale, from 0 - Not at All to 3 - Nearly Every Day. Total score on the PHQ-9 ranges from 0 to 27, with higher scores indicating more severe impact of depressive symptoms on an individual's life.
Measured: Before treatment, within a week after treatment, and one month after treatment
Change in anxiety symptoms as measured with the Generalized Anxiety Disorder (GAD-7)
The seven-item Generalized Anxiety Disorder (GAD-7; Spitzer et al., 2006) is a gold-standard measure of anxiety symptoms an individual experienced in the prior two-week period. Items are rated on a 4-point Likert scale, from 0 - Not at All to 3 - Nearly Every Day. Total score on the GAD-7 ranges from 0 to 21, with higher scores indicating more severe impact of anxiety symptoms on an individual's life.
Measured: Before treatment, within a week after treatment, and one month after treatment
Treatment satisfaction
Participants are invited to rate on a 5-point Likert scale, from 1 - Strongly Disagree to 5 - Strongly Agree, designed specifically to assess their level of satisfaction with the intervention received in the current study. They are also asked in an open-ended way to provide qualitative feedback on the program, including their overall or any specific experience with the program not otherwise captured by the pre-set prompting questions.
Measured: Within a week after treatment
