Plain English Summary

Background and study aims
Cross-sectional studies show positive correlations between psychological wellbeing and religiosity. Most religious patients prefer to discuss religious topics during their therapy. However, it is virtually unknown whether addressing religious issues in psychotherapy increases the effectiveness of psychotherapy of religious patients, as are potential moderating and mediating mechanisms. The main aim of the study is to investigate the influence of discussing religious issues during therapy on treatment outcome, both 6 months after the start of treatment and 1.5 years after the start of treatment. In addition, the study will take possible mediating variables into account, such as cognitive schemas, image of God, and therapeutic alliance. Structural features of personality pathology will be investigated as moderator variables.

Who can participate?
Patients aged from 18 to 65 years who apply for psychotherapy at a mental health institute that is involved in this study and who have been assigned to psychotherapy of 1 to 12 months duration with about 5 to 40 sessions

What does the study involve?
Patients are randomly allocated to:
1. Regular therapy including approximately 15 minutes of talking about religious or spiritual themes each session
2. Regular therapy without talking about religious or spiritual subjects
All patients fill in questionnaires before treatment, 6 months after the start of treatment, and at follow-up 1.5 years after the start of treatment.

What are the possible benefits and risks of participating?
Participants will contribute to expanding and deepening scientific knowledge about the effectiveness of psychological treatments for religious patients. Filling in the questionnaires can make some patients emotionally upset. Clinical experience however shows that these emotional reactions do not frequently occur or are of short duration. Furthermore, there is a risk of disappointment for patients depending on the group they are assigned to.

Scientific titleThe influence of attention to religion in psychological therapy in the short- and long-term on the change in psychological functioning, and the contribution of the possible mediating variables: cognitive schemes, the image of God, and therapeutic alliance and the possible moderating variable: structural personality traits
Study acronymR/S therapy
Study hypothesisThe main aim of the study is to investigate the influence of discussing religious issues during therapy on treatment outcomes, both 0.5 and 1.5 years after starting treatment.

In addition, the study will take possible mediating variables into account, such as cognitive schemas, image of God, and therapeutic alliance. Structural features of personality pathology will be investigated as a moderator variable.

Hypothesis: Treatment where religion/spirituality is part of the therapy is slightly more effective than treatment as usual, especially for depressed patients.

Approved 18/03/2009, Leiden University Medical Center, METC (Albinusdreef 2, Leiden, 2333 ZA, Netherlands; +31 (0)71 - 5265106; metc-ldd@lumc.nl), ref: P08.107/DT/ib

ConditionMental disorders
InterventionThe method of randomisation was per participating institution by order of enrollment. The first subject was assigned to the 'yes group' and the second to the 'no group', and so on.

Patients are randomized into:
1. R/S based therapy. An R/S-based therapy is a regular therapy including approximately 15 minutes of talking about religious or spiritual themes each session.
2. Non-R/S based therapy. A non-R/S-based therapy is a regular therapy without talking about religious or spiritual subjects.

After each session, the therapist records the number of minutes spent on R/S subjects and the type of intervention. (http://geloofintherapie.nl/index.php?option=com_bfsurvey_basictrial&view=onepage&catid=1&Itemid=5)

To measure the influence of desirability, before the start of treatment each patient is asked the question: 'It is possible that religious themes are discussed in your treatment. How desirable do you think that is on a scale of 1 (absolutely not) - 8 (absolutely yes).'

At three times, all patients fill in questionnaires: (T0) before treatment; (T1) 6 months after the start of treatment; and (T3) at follow-up 1.5 years after the start of treatment.

Patients complete the following questionnaires:
1. Brief Symptom Inventory
2. Rand-36
3. Spiritual Well-Being Scale
4. Dutch Abbreviated MMPI (NVM)
5. Young Schema Questionnaire (YSQ)
6. God Image Questionnaire (VGB)
7. Working Alliance Inventory (WAI)

The total duration of interventions depends on the overall duration of treatment. It is tailored to the individual patient and can vary. In the intervention group, the 'intervention' (talking about religion/spirituality) is applied for between 10 and 15 minutes per session and this time is recorded by the psychologist.
Intervention typeBehavioural
Primary outcome measureChange in psychological functioning:
1. Self-reported clinical relevant psychological symptoms measured using the Brief Symptom Inventory
2. Overall well-being self-reported using Rand-36
3. Spiritual well-being self-reported using the Spiritual Well-Being Scale
All measured at T0 before treatment; T1 6 months after the start of treatment; and T2 at follow-up 1.5 years after the start of treatment
Secondary outcome measuresChanges in variables that could mediate or moderate changes in psychological functioning after psychotherapy:
1. Personality traits measured using the self-report Dutch Abbreviated MMPI (NVM) at T0 only
2. Self-reported maladaptive schemas that lead to unhealthy life patterns assessed using the Young Schema Questionnaire (YSQ) at T0, T1 and T2
3. Feelings experienced in relation to God and how a person perceives God's actions, self-reported using Dutch VGB (God Image Questionnaire) at T0, T1 and T2
4. Evaluation of the collaborative relationship between the patient and therapist measured by the Working Alliance Inventory (WAI) and completed by both the patient and therapist at T1 only
