About this trial
The goal of this study is to examine the effectivity of two self-esteem interventions (COMET (Korrelboom) and CBT (De Neef)) in a general psychiatric population.
The main questions it aims to answer are:
* is there a difference between the two interventions in effectiveness on increasing self-esteem? * is there a difference between the two interventions in effect on levels of anxiety, depression and general mental health? * are found effects on levels of anxiety, depression and general mental health associated with changes in self-esteem? * is the ability to use imagination a moderator for outcomes in both conditions?
Participants are randomised over both conditions. At baseline (T0), end of treatment (T1) and follow-up at 6 months (T2) several outcome measures are conducted, such as RSES, DASS and MHC-SF.

Rosenberg self-esteem scale (RSES)

The DASS consists of three subscales of 14 items: Depression, Anxiety and Stress. Total scores on the subscales range from 0 up to 42, with higher scores indicating a higher levels of distress.
Mental Health Continuum - Short Form (MHC-SF)
Mental Health Continuum - Short Form is a 14 item questionnaire with items to be rated on a 6-point Likert scale, ranging from 0 (never) to 5 (every day). Higher scores mean a better outcome. Total score intends to measure positive mental health as a distinct indicator of mental well-being. Three subscales are Emotional well-being (presence of positive feelings), Psychological well-being (positive functioning in individual life) and Social well-being (positive functioning in community life). Higher scores indicate more well-being.
Plymouth Sensory Imagery Questionnaire (PsiQ-NL-35)
Plymouth Sensory Imagery Questionnaire is a 35 item questionnaire. It assesses mental imagery vividness on 5 items for 7 modalities (i.e., vision, sound, smell, taste, touch, bodily sensation and emotion). Each of the 7 modalities have a heading such as 'imagine the smell of…', followed by 5 items such as 'a rose' or 'burning wood'. Items are to be rated on a 11-point scale (0-10), ranging from 0 (no image at all) to 10 (as vivid as real life).
