User Information

Acronym:

SD-TC

Author/Developer / Address:

Universidad Autónoma de Barcelona. Departamento de Psicología de la Salud y de Psicología Social. Edificio B. 08193 Bellaterra (Barcelona). Spain

Publication dates:

Unpublished Doctoral Dissertation (1998). School of Psychology. UAB.

Description / Type of Assessment:

SD-TC is an adaptation of the Semantic Differential (Osgood) for residential programs (therapeutic Communities). It is a self-reported instrument. Each domain evaluated is scored on several bipolar adjectives. These adjectives are scored ranging 1- to -7, where one is the most favourable position and 7 is the most unfavourable position.

Primary use / Purpose:

SD-TC was designed to provide information useful for structure and process evaluation in residential therapeutic communities for substance misusers.

Domains measured / Life Areas / Problems Assessed:

  • Treatment (18 adjectives),
  • Services (24 adjectives),
  • Professionals -staff (20 adjectives),
  • Users (17 adjectives).

Population:

SD-TC is designed to be used with Residents (version for residents) and Staff and Directives (Version for the Technical team).

Administration / Completion Time:

25-30 minutes

Scoring Procedures:

The adjectives for each domain are averaged to obtain a whole score for these domains.

Scoring Time:

5 minutes.

Credentials/Training:

Psychologists, Social Workers, Qualified staff.

Source of Psychometrics:

SD-TC has content and face validity and internal consistency. (See relevant studies).

Languages:

Spanish

Price:

Cost-free. The authors permit the use of the SD-TC with no costs for not-for-profit applications. Users are asked to cite the following reference when using the instrument:Gutiérrez-Rosado, T. (1998) Evaluación de programas de Comunidades Terapéuticas para drogodependientes: estructura, procesos y resultados. Departamento de Psicología de la Salud y de Psicología Social. Facultad de Psicología. Universidad Autónoma de Barcelona. Spain.

Practicability / usefulness:

To obtain a generalised feedback from clients and staff of residential therapeutic communities on the treatment, services, human resources and residents. SD-TC is useful as a first approach in the evaluation process, when it may indicate the need of conducting a more detailed evaluation.

Comments:

The SD-TC should be applied once the residents know the program functioning. The moments most suitable are after four months of residential treatment and at the end of treatment.

Psychometric properties of the Semantic Differential for Therapeutic Communities: reliability and validity.

Psychometric properties of the SD-TC were explored initially with a sample of 55 individuals (8 staff members and 44 users of a therapeutic community). In a first step, the scales with a non-adequate discriminant capability were eliminated from the instrument.

Reliability of the SD-TC was assessed by two methods: split-half reliability and internal consistency (alpha coefficient). Alpha coefficients ranged from 0.76 to 0.93, with all coefficients but one higher than 0.85. Split - half correlation coefficients (Spearman - Brown) also achieved a mean value higher than 0.80.

Validity of the SD-TC was assessed by analysing correlations between SD-TC and scores on a related measure: The Evaluation Interview for Therapeutic Communities (Gutiérrez-Rosado, 1998). Scores obtained with these two instruments were closely related, and no significant differences were found between them for all these four dimensions but for "residents" domain.

In resume, scores obtained with the Semantic Differential for Therapeutic Communities showed sound psychometric properties in this study. SD-TC may be used as useful measure for treatment evaluation research in therapeutic communities for substance misusers.
