Description / Type of Assessment:

TSR is a structured interview that assesses the nature and frequency of treatment services provided for a client in the following domains.

Primary use / Purpose:

The TSR was designed to fill the need for measures that identify the nature and quantify the amount of treatment services provided to clients in substance abuse treatment programs.

Domains measured / Life Areas / Problems Assessed:

Treatment services are assessed in the following problem domains:

  • Medical problems.
  • Substance use (alcohol and drug) problems.
  • Employment and support problems.
  • Family problems.
  • Legal problems.
  • Psychological / emotional problems.

Each domain of the instrument is composed of three sections. The first section requires a report on the number of days that a target behaviour or problem occurred. The second section inquires about the number of times (during a week) that a professional has provided services. The third section records the number of significant sessions that occurred for a particular problem domain during the previous week.

The services provided in each problem area include treatment in the index treatment program (in-program) and from other providers (out-program).


Adults. The TSR may be administered weekly to an individual or to a small group of individuals as an interview or as a supervised self-report when the patient has accrued repeated experience in the use of the instrument.

Administration / Completion Time:

The TSR interview requires approximately 10 minutes when administered by a skilled and trained technician, whether in person or over the phone.

Scoring Procedures:

Scores are obtained by calculating unweighted summary or composite scores for the total number of services provided and for the significant discussions received during each week of treatment.

Scoring Time:

1-2 minutes.


A minimum number of training sessions is recommended.

An administration manual accompanies the instrument to help train interviewers and serve as a resource during actual administration of the interview.

Availability / Inquiries:

The TSR is in the public domain.

Practicability / usefulness:

The TSR can be a useful instrument to obtain:

  1. An ongoing record of the number and types of services provided to substance abuse clients during treatment. This can be useful to make cost-effectiveness determinations and as a means of monitoring the proportion of the patient population that actually receives the available services.

  2. A during-treatment evaluation of the extent to which the problems identified at admission are actually addressed over the course of treatment; and the rate at which these identified problems show change during treatment.


The TSR is designed for use in conjunction with the Addiction Severity Index (ASI). While the ASI assesses treatment needs of clients in each of it problem domains, the TSR assesses the nature and frequency of services provided in the same domain.
