Validation of the Dutch Translation of the Tobacco, Alcohol, Prescription Medication and Other Substances (TAPS)-Tool

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to investigate the reliability and validity of the Dutch version of the TAPS-tool. This will be investigated in 2 groups: patients without intellectual disabilities treated in Flexible Assertive Community Treatment (FACT) teams and patients with intellectual disabilities. For the later group, an adjusted version of the TAPS-tool will be developed. For both groups the TAPS outcome will be compared to a golden standard.

Detailed Description
-----------------
All FACT teams in the participating organization (GGZ Oost Brabant) work through a standardized care pattern which implicates screening and assessment on several areas. At the start of the treatment all patients are assessed for intellectual disabilities, trauma related symptoms, addiction, quality of life, level of psychiatric complaints, social functioning, and phase of recovery. Subsequently quality of life and the level of psychiatric complaints is measured yearly. For this research question a small golden standard instrument was added to the standard screening and assessment. For people with intellectual disabilities (ID) who get an extensive assessment of substance use problems in their (standard) treatment, permission to participate on the TAPS (version for ID) was asked.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| TAPS | The TAPS-tool is a 2-phase screening instrument to detect substance use problems which can be used as an interview or as a self-administered questionnaire. TAPS 1 has a score from 0-4 (higher is more substance use). For a score of 1 or higher, TAPS 2 is also taken. TAPS 2 has a total score from 0-3 (higher is indication of more problematic use) for all of the 8 substances. Cut off score is +2. | one assessment at the start of the treatment | 
| Measurement of Addiction for Triage and Evaluation (MATE) | MATE is an instrument, developed in Europe to determine patient characteristics for the indication of care for people with addiction problems on a valid and reliable way. The MATE will be used for participants without intellectual disabilities. Modules 1, 4, and Q1 are used in this study. Module 1 (interview about substance use) for alcohol, nicotine, cannabis, opiates, cocaine, stimulant drugs, extacy, other drugs, sedative medicines and gambling. For every substance there is a cut off point for excessive use. There are no scores for module 1. Module 4: 11 binary questions (yes/no) about dependency and misuse of the problem area. The scoring range is 0 to 9 (cut off = 8). the higher the score, the worse the dependency. Module Q1: five questions about desire, based on a five point Likert-scale (score 0-4). Cut off = sum score > 12. higher scores stand for more problematic desire. | At the start of FACT treatment, only for participants of this study | 
| Substance use measurement for people with intellectual disabilities (SumID-Q) | The SumID-Q is an extensive Dutch assessment instrument (interview) on substance use problems for people with intellectual disabilities. There are no total scores. | Standard assessment at the start of the treatment, or when substance use problems are suspected | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Health of the Nation Outcome Scales (HoNOS) | The Health of the Nation Outcome Scales (HONOS] is a scaling device routinely used by the mental health services in Anglo-Saxon countries in order to map a patient's mental state and any changes that may have occurred in it. The 12 questions are scored from 0-4. 0 = no problems; 4 = very serious problems. Psychometric properties of the HoNOS are satisfactory to good (Mulder et al., 2004). There is a total sum score available (and reference group: patients with severe mental illness).. | Once at start of FACT treatment | 
| Manchester abbreviated quality of life measure (MANSA) | Self administered questionnaire on quality of life. The MANSA is a multi-dimensional questionnaire which consists of 16 items. Twelve items determine patient satisfaction with their life as a whole, employment, financial situation, number and quality of friendships, leisure activities, accommodation, personal safety, social network, sex life, relationship with family, physical health and mental health. Satisfaction on these items is rated on a seven-point rating scale (1 = extremely negative, 7 = extremely positive). Four objective items assess the existence of a 'close friend', whether there was contact with a friend in the last week, accusation of a crime, and victimization of physical violence (yes / no). These objective items do not count in the calculation of the total score. In this research, the summed scores were used. | Once, at start of FACT treatment |
